organisation, an association of nine institutions with research and development in the field of Telecommunications: • Instituto Superior Técnico (IST); • Universidade de Aveiro (UA); • Universidade de Coimbra (UC); • Portugal Telecom Inovação, (PTIn) • Nokia Solutions and Networks S.A • Universidade da Beira Interior (UBI) • Universidade do Porto (UP) • ISCTE – Instituto Universitário de Lisboa (ISCTE-IUL) • Instituto Politécnico de Leiria (IPL) it is organised around three sites: • Aveiro, in the University Campus, • Coimbra, in Site II of the University of Coimbra, • Lisbon, in Instituto Superior Técnico, and four branches: • Leiria, in the “Escola Superior de Tecnologia e Gestão” of the Leiria Polytechnic (IPL), • Covilhã, in the University of Beira Interior (UBI), • Porto, shared by the Faculty of Engineering (FEUP) and the Faculty of Sciences of the University of Porto (FCUP), • Lisboa, in (ISCTE-IUL). Setting up of it was the result of a 1.5 billion escudos (about 7.5 million Euros) grant from Programme CIENCIA, through three contracts signed in 1991. This investment enabled new infrastructures to be built and research laboratories to be equipped at each site. Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994. Since 1993, it activities proceed regularly. 6 ANNUAL REPORT 2015 – KEY IT INDICATORS it bylaws were first approved in 1992, modified in 1997, 2003, 2011, 2014 and 2015. New Site regulations deriving from it bylaws were approved and implemented in 2011. Key developments in 2015 are highlighted ahead. Details are included in the sections dealing with each of the research areas. 1.2 Management it is managed by a Board of Directors, elected by the General Assembly, and by Site Management Boards, which include the site members of the Board of Directors. Site Management Boards enjoy ample freedom to deal with current affairs and usually meet weekly. The Board of Directors meets at least once a month. it scientific activities are overseen by the Scientific Board, which includes all it researchers holding a Ph.D. degree. The Scientific Board meets in Plenary or in Committees, both permanent and temporary. There are two permanent committees: the Science and Technology Committee and the Research Group Coordination Committee. it Work Plan and the Annual Report are discussed with the Advisory Committee, formed by three independent experts in the field of telecommunications (Prof. Sir John O’Reilly, Prof. Touradj Ebrahim and Prof. Thomas Brazil) acting in a personal capacity, and together with the Accounts Report (after legal certification) are subsequently submitted to the General Assembly for approval.1 The General Assembly met formally twice in 2015. The first meeting was held on March 25th, at ISCTEIUL premises, Building II, to discuss and approve the 2014 Annual Report and Accounts and to discuss and approve an amendment to it statutes. The second meeting took place on December 22th, again in the Meeting Room of the Aveiro site, to discuss and approve the Work Plan and Budget for 2016 and to discuss and to approve a further amendment to it Bylaws required by law. The Research Group Coordination Committee also met twice during 2015. On the first meeting, held on March 18th, at ISCTE-IUL premises, Building II, Room B103, Lisboa, the Draft Proposal of the 2014 Annual Report was discussed and received a favourable opinion and the intermediate reports of the first batch of internal projects were presented and discussed. 1 it would like to pay tribute to Prof. Martin Tomlinson, for all the help, support and friendship since 1998 7 ANNUAL REPORT 2015 – KEY IT INDICATORS On the second meeting, held on December 16th, Meeting Room of the Aveiro site, the Work Plan and Budget for 2016 was discussed and received a favourable opinion. The proposal for an Engagement Index was thoroughly discussed and rejected while its main ideas should be included in a Code of Practice to be discussed in the next meeting. 1.3 Highlights of 2015 In 2015, in spite of serious reduction of funding, mainly from FCT strategic funding, the momentum built in previous years enabled achieving a significant scientific output: • 11 books; • 61 book chapters; • 387 papers in international refereed scientific journals; • 545 papers in refereed conferences, with published proceedings; • 9 patents where the forecast was: • 15 books; • 50 book chapters; • 250 papers in international refereed scientific journals; • 450 papers in refereed conferences, with published proceedings; • 8 patents Achieved scientific output exceeded by far our forecast, namely in the number of papers in international refereed scientific journals. The small reduction in the number of books may be attributed to the reduction in funding. Fostering advanced education was also maintained at very high levels: • 34 PhD theses, submitted and approved, • 262 MSc theses, submitted and approved, where the estimated numbers for 2015 were: • 35 PhD theses, submitted and approved, • 200 MSc theses, submitted and approved. 8 ANNUAL REPORT 2015 – KEY IT INDICATORS The number of PhD theses submitted and approved decreased significantly from the previous year when it reached an all time high (62). The number of MSc theses submitted and approved exceeded significantly our forecast. This may be due to the fact that during 2015 we checked far more thoroughly the number of MSc theses and the current value should be much closer to the real value than in previous years. The number of scholarships decreased significantly in 2015 with respect to 2014, not only due to the reduction FCT strategic funding (as explained in more detail below), but also and mainly because of the decrease in the number of scholarships funded by FCT: • 224 Ph.D. scholarships, funded by FCT, • 143 other scholarships, funded by it as follows: • 24 post-doc scholarships; • 26 scholarships for BSc graduates; • 84 scholarships for MSc graduates; • 8 R&D starting grants; • 1 S&T management; During 2015, 155 projects, of which 126 nationally funded and 29 internationally funded projects were active, as shown in section 2.2. It is particularly noteworthy the fact that on the 31st of December it was involved in running 18 FP7 projects and 14 projects funded by industry (2 of which international). It should be noted that not all projects mentioned in section 2 are funded through it. In the past few years, FCT strategic funding, ie. funding for the IT - Laboratório Associado contract, in addition to a sharp decrease was never timely. Strategic funding for the period 2011- 2012 was 3.0 M€/year, for the period 2013-2014 to 1.6 M€/year (100 % execution rate) and for the 2015 to 1.2 M€. In spite of the fact that the first payments for the period 2013-14 came in with a 9 month delay (August 30th, and October 31st 2013) FCT imposed the 31st of December 2014 as the closing date for the contract. Later this date was postponed (albeit with a penalty) to the 31st of March 2015. In effect the 9 ANNUAL REPORT 2015 – KEY IT INDICATORS penalty meant a delay in the execution of the 2015 funding, that run from April 1st, 2015 to March 31st, 2016. With the delay and the new procedures introduced by our General Director, it managed to execute 100 % of the 2014 funding. Due to the fact the 2015 strategic funding may be used up to March 31st, 2016, the execution rate for the 2015 strategic funding is not yet available. As mentioned in the Annual Report for 2013, during 2013 FCT decided to organize an evaluation of all Portuguese R&D units making it possible for these units to adopt configurations other than the current one. Although the funding rules favored smaller units, it, faithful to its principles, decided to keep the same structure. The proposal was submitted on the 30th of December 2013. The proposal evaluation ran in two phases. For the first phase the proposals were evaluated in four criteria (with grades from 1 to 5 in each item): A. Scientific productivity and contribution to the National Scientific and Technological System; B. Scientific and technological merit of the research team; C. Scientific and innovative merit of the strategic program; D. Feasibility of the work plan and reasonability of the requested budget. The results of the first phase were made public on the end of June 2014. Most surprisingly it got very low marks (15/25), distributed as follows: A=4, B=4, C=3 and D=4. Even if the total (15/20) would allow access to the second phase, the 3 in item C would forbid it. In addition to many factual errors and mocking phrases that should never be used in an evaluation report (according to FCT published guidelines), the evaluation report showed hints of manipulation to achieve a pre-defined result. It suffices to say that C=3 was not the average grade of the (supposed) 3 evaluators. The average grade of 3 was in item D a situation that would not bar it from the second phase. 10 ANNUAL REPORT 2015 – KEY IT INDICATORS In the first phase rebuttal it appeal was successful and the overall marks was amended to 16/20, A=B=C=D=4. The visit, the major item of the second phase of the evaluation, had strict rules (imposed by FCT) that did not take into account neither the number of sites nor the number of researchers or students involved in the research unit. The visit had to be restricted to one site and 3 hour duration (1 hour with the directors, 1 hour lab visit and1 hour meeting with researchers and students. For the second phase a further item of evaluation was added: E. Impact of the scientific, technological and cultural output. it decided to stage the visit in the Aveiro site and to prepare a rather imposing poster and demo session (with 107 posters, 20 demos and about 200 researchers and students). It was pretty obvious after the visit that three evaluators were well impressed. And surely the evaluation report bear it out. The overall grade was 22/25 (VERY GOOD), with A=4, B=4, C=5, D=4, E=5. So, for the second time, it strategy was re-evaluated, now to the maximum (further confirming our initial suspicions). According to the law it appealed again, on the 19th of January 2015, this time after having had access to the evaluation forms of the other research units in the area, in particular the only one that had been graded higher than it. The appeal resulted in an increased from 22/25 to 22.5/25 (VERY GOOD), 0.5 points short of the Excellent label it we believe is due. On June 8th, 2015, it appealed yet again, now on the basis of unfair comparison with research units in the same scientific area, with higher marks. On February 26th, 2016, as the result of the last appeal it was finally graded EXCELLENT (23/25). As a consequence it funding would get a significant boost. On September 17th and 18th it organized the 10th edition of its international conference Conftele 2015. This time the conference was embedded in a technology fair, TECHDAYS, organized together with the Universidade de Aveiro, INOVARIA, TICE.pt and the Aveiro Municipality held at Aveiro EXPO. The conference had 157 participants. The technology fair included 54 exhibitors in addition to it own 11 ANNUAL REPORT 2015 – KEY IT INDICATORS prototypes and demonstrations. The number of participants (1127) is a tribute to the growing public interest in it research and development products. The Advisory Committee visited the Aveiro site, on the 16th of September and Conftele 2015 and TECHDAYS, on the following 2 days. During this visit the Advisory Committee had the opportunity to examine in detail some of the latest it research work and held most fruitful discussion with the Management Committee and with many researchers. The Advisory Committee report has already been sent to the associates and to FCT. During 2015 one it researcher, Prof. Mário Silveirinha was elevated to the grade of Fellow of the IEEE (Institute of Electric and Electronic Engineers) and three it researchers, namely Prof. Dr. Fernando Pereira, Dr. Jonatan Rodriguez and Prof. Dr. Rafael Caldeirinha were elected to the grade of Fellows of the IET (Institution of Engineering and Technology). Also in 2015, two it researchers, Prof. Dr. José Bioucas Dias and Prof. Dr. Mário Figueiredo were named Thomson Reuters Highly Cited Researchers 2015, the latter for the second time in a row. It is also worth while mentioning the “Outside Team Award”, from Hauwei Technologies Sweden, for outstanding collaboration in the design of microwave frequency power amplifiers. In addition to the above during 2015 it researchers were awarded the following prizes: - 1 “ANACOM-URSI Portugal 2015 Award”; - 1 EuMC Microwave Prize; - 1 Award Abreu Faro, for the best PhD Thesis submitted to IST; - 1 Best Iberian Thesis on Information Systems and Technologies; - 2 Young Engineers Innovation Award (1st and 2nd place); - 1 “Novas Fronteiras da Engenharia” prize from “Ordem dos Engenheiros”; - 4 Fraunhoffer Challenge 2015, 1st and 3rd place PhD, 2nd and 3rd place MSc; - 1 iUP25k 2015 prize, 1st place; - 1 Bresimar “Ideas Contest for Electronic Products 2015”, 1st prize; - 1 Siemens Innovation and Excelence Award; - 1 IEEE Communications Letters “Exemplary Reviewer Award; - 1 Pattern Recognition Letters “Top Reviewer 2011-2012”; - 10 “Best Paper Award”, of which 1 are “Best Student Paper Award”. 12 ANNUAL REPORT 2015 – KEY IT INDICATORS During 2015 it hosted the following national and international events (details in each scientific area): - 18 Seminars; - 5 Talks; - 1 Colloquium; - 2 Workshops; - 2 One-week short courses for secondary school (20 pupils each); - 2 Winter/Summer Schools; - 1 Technology Fair (TECHDAYS); - 4 major International Conferences. it is a member of the CIENCIA VIVA, the National Agency for Scientific and Technological culture and cooperates in some of its events. Sponsored by CIENCIA VIVA, it organised a one-week, from June 30 to July 4, hands-on introductory course on telecommunications for 10th, 11th an 12th grade high school pupils with 20 enthusiastic participants and an open-lab two hour session for a similar audience. Also in cooperation with IST, it organised visits and demonstrations for high school pupils, involving about 800 pupils (in 2015). During 2015 it continued the regular publication of its monthly newsletter, which is distributed electronically to all researchers and PhD students, and also continued its presence in social networks (Facebook, YouTube and Flickr). 13 ANNUAL REPORT 2015 – KEY IT INDICATORS 2 Key IT Indicators 2.1 Human Resources In December 2015 it human resources included 761 people distributed as follows: • 306 researchers (of which 24 were it grantees); • 224 PhD students • 119 other it grantees (84 MSc, 26 BSc, 8 R&D starting grants, 4 R&D integration and 1 R&D management); • 11 technical; • 18 administrative. All researchers but 2, hold a PhD degree. As a result of the application of it quality policy, out from the 304 researchers holding a PhD Degree, this is equivalent to 141 FTE (full time equivalent). The distribution of all human resources between the three sites is represented graphically in Figure 1. It is obvious from this figure that the ratios between PhD students and researchers and grantees and researchers is much higher in Aveiro than in Lisbon a fact that is partly explained by the much higher involvement of Aveiro in FP7 projects. 160 140 120 100 80 60 Lisbon 40 Coimbra 20 Aveiro 0 Figure 1: Distribution of it human resources between the three sites 14 ANNUAL REPORT 2015 – KEY IT INDICATORS The distribution of researchers PhD students and grantees between sites is shown in Figure 2. 200 150 Researcher 100 PhD Student Grantees 50 0 Lisbon Coimbra Aveiro Figure 2: Distribution of researchers students and grantees per site In Figure 3 we plot the distribution of researchers and PhD students among associated universities. 90 80 70 60 50 40 30 20 10 0 Researcher PhD Students Figure 3: Distribution of it researchers and PhD students among associated universities 15 ANNUAL REPORT 2015 – KEY IT INDICATORS The distribution of it technical and administrative staff is shown on Figure 4. 10 9 8 7 6 5 4 3 2 1 0 Technical Administrative Figure 4: Distribution of it technical and administrative staff The distributions of foreign post-docs (34) and PhD students (48) per nationality are shown in figures 5 and 6.

Researchers Male Female Figure 7: Distribution of researchers per gender 17 ANNUAL REPORT 2015 – KEY IT INDICATORS PhD Students Male Female Figure 8: Distribution of Phd students per gender The scientific productivity in 2015 was 1.6 journal papers per researcher holdind a PhD (or 2.74 journal papers per FTE). Counting each book, bookchapter and journal paper as one publication, the ratio becomes 1.5 publications per eligible researcher (3.25 per FTE). It is interesting to compare the distribution of the number of researchers per Site and Branch with the number of number of published works (papers in international journals and communications to refereed conferences). One should note that the sum of the number of publications per Site and/or Branch is higher than the number of publications for it because a significant number of publications (about 30 %) are authored by researchers from more than one Site and/or Branch. This fact in itself is an important indicator that it is increasingly operating as a unity rather than as a collection of research units. In the following, it and CIENCIA paid researchers and their publications are not included. 18 ANNUAL REPORT 2015 – KEY IT INDICATORS Researchers Lisbon Coimbra Aveiro Figure 9: Distribution of it researchers per site in 2015 PhD students Lisbon Coimbra Aveiro Figure 10: Distribution of it PhD students per site in 2015 Staff (technical) Lisbon Coimbra Aveiro Figure 11: Distribution of it staff (technical) per site in 2015 19 ANNUAL REPORT 2015 – KEY IT INDICATORS Staff (administrative) Lisboa IST Lisboa ISCTE Porto Covilhã Coimbra Aveiro Figure 12: Distribution of it staff (administrative) per site/branch in 2015 PhD students Lisboa IST Lisboa ISCTE Porto Coimbra Covilhã Aveiro U.

Differences are considerable at the number of patents (as would be expected given the small number of patents involved). Major differences are at Covilhã and Lisboa ISCTE, the former with more journals papers and the latter with fewer journal papers than their number of researchers. As far as conference papers, Lisboa ISCTE stands out with a higher share of output compared to its share of researchers. Networks and Synergies it has been trying hard to improve networking not only between its researchers but also with external researchers. Using it database of journal and conference publications in 2015 figures 18 and 19 were produced representing it co-authorship network in 2015. In this figure each researcher is represented by a symbol whose colour indicates the researcher scientific area according to the following colour code: • Red — Wireless Communications; • Blue — Optical Communications; • Orange — Networks and Multimedia; • Green — Basic Sciences and Enabling Technologies; • White – External Author. The nodes´symbol shape is different according to the researcher´s Site. The node size is proportional to the number of connections originated by each node. The existence of a paper authored by two or more researchers is represented by a line linking the nodes involved. The networking strength is apparent in Figure 19. Although most connections involve researchers in the same scientific area, there is a significant number of connections between researchers of different scientific areas, a clear indicator of the synergies it is fostering. On the other hand networking outside the same scientific area is almost non-existing in journal papers (Figure 18) an indication that long term collaboration between researchers of different areas and or sites is not yet widespread. However these links start to appear when we carry out the same exercise accumulating data from more than one year (not shown in this report), an indication that out of the scientific area collaboration in Journal papers is sporadic but it exists. 22 ANNUAL REPORT 2015 – KEY IT INDICATORS Figure 18: Graph showing journal papers co-authorships in 2015 23 ANNUAL REPORT 2015 – KEY IT INDICATORS Figure 19: Graph showing conference papers co-authorships in 2015 24 ANNUAL REPORT 2015 – KEY IT INDICATORS 2.2 Projects Funding Agency Number ADI 6 Ciência Viva 2 COST 10 CAPES 3 COMPETE 1 EDP 1 ESA 3 EU 21 FCT 56 FCT/CMU 3 Internos 28 Ministério Defesa 4 Outros - nacionais 2 Outros - internacionais 3 PT Inovação 2 QREN 8 Serviços – empresas nacionais 9 Serviços – empresas internacionais 2 Total 164 Table 1 – Number of active projects in 2015, according to funding source 2.3 Publications Books Book Chapters Journals Conferences Patents MSc Thesis PhD Thesis 11 61 387 438 9 262 34 Table 2 – Number of published works in 2015 "Books"- Fully authored books, Editor books, "Journals"- Papers in International refereed journals "Conferences"- Communications in International and National refereed conferences; "Patents" - Patent applications; "MSc and PhD Theses"- Concluded dissertations.; 25 ANNUAL REPORT 2015 – FINANCIAL OUTLINE 3 Financial Outline Operational income during 2015 totalled 6.302k€, with its main items distributed in Table 1.

Acron / Ref PROENERGY-WSN PTDC/EEA-TEL/122681/2010 Title Prototypes for Efficient Energy Self-sustainable Wireless Sensor Networks Funding FCT/PTDC Descript. The main challenge is the development of an energy self-sustainable wireless sensor network formed by nodes with energy scavenging capabilities. Body and movement energy scavenging will be considered whilst maximizing the energy efficiency. One of the bottlenecks of the wireless sensor devices performance is the batteries and energy storage. For indoor environments, rechargeable batteries may be the solution, although recharging the batteries may be burdensome especially for the elderly people. As solar cells are not viable with body-worn sensor nodes (because sensors are preferred to be placed under the clothing), motion and body heat based energy harvesting techniques should be investigated for healthcare and body monitoring systems.

Besides these Wireless Body Area Network (WBAN) aspects, contributions will be given on the development and experimental verification of a hardware solution for WSN protocol performance evaluation. This study relates to the modelling and experimental evaluation of WSN routing and link layer protocols with no degradation in the sensor nodes performance. Two contention-based WSN MAC protocols will be compared via modelling, simulation and hardware experimental measurement approaches. Not only will the energy spending be addressed, but also throughput, packet delivery rate, and end-to-end delay. Routing protocols that save energy are also aimed at, and different QoS metrics will also be considered, trying to reach a solution that uses the least energy possible, while delivering all the packets with a very low latency. Aspects of hybrid energy storage will be considered both in the simulations and hardware verification, envisaging the improvements to be achieved for the network protocol proposal.

Acron / Ref VTL PTDC/EIA-CCO/118114/2010 Title Semáforos Virtuais Funding FCT/PTDC Descript. Urban transportation is one of the grand challenges of our times. Car journeys are by far the main player in this transportation, comprising 72% of all passenger kilometers in the European Union (EU) [1]. Traffic congestion on the road is thus a common reality of the major EU cities, and has been estimated to cost as much as 1% of the GDP. In its present form, the use of Traffic Lights (TL) to control and regulate this road traffic has proven to be very costly and inadequate in terms of scalability. Leveraging the new vehicle-tovehicle (V2V) communication capability of modern cars we propose to design and validate an alternative scheme of urban traffic control that envisions TL as in-vehicle virtual signs, enabling ubiquity of signalized intersections, and defining the synchronization of light phases, cycle durations and green splits based on distributed and self-organization techniques that govern a vehicular ad hoc network (VANET). The nonscalability of TL, and in particular the non-scalability of an adaptive and intelligent citywide system of TL (a recent survey reports that 70-90% of the deployed TL are nonadaptive [2]) is a key aspect that we shall address through the alternative approach 40 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS proposed in this project. Even New York City only has 10,800 of its 45,000 intersections managed by TL [3]. In other cities this percentage is typically smaller. In addition to traffic flow improvement, TL have also a significant impact on road safety, as studies report a 33% decrease in vehicle crashes at intersections that have been equipped with traffic signals [4]. Our approach in this project will take advantage of the mandatory adoption by the automotive industry of the Wireless Access for Vehicular Environments (WAVE) protocol, and the ability of vehicles to communicate with each other, thus creating a distributed and highly reliable system of in-vehicle virtual traffic lights (VTL). Our preliminary simulations of this self-organizing traffic paradigm show a potential to increase the average flow rates substantially (up to 60%, compared with a city-level physical TL system [5]), in addition to rendering traffic control and management more ubiquitous and cost-effective. Our basic idea is relatively simple: use the core characteristics of VANET, namely periodic beaconing, location tables and appropriate transport and MAC protocols to perceive crossing conflicts and elect a leading vehicle that works as a temporary virtual infrastructure, stopping under a virtual red light at the entrance of the intersection and broadcasting virtual traffic light messages that are listened by the vehicles approaching the intersection. Local optimization of cycle duration, phase layout and green splits are computed based on the number of vehicles in each approach. City-level optimization of traffic flow can resort to the synchronization of leaders in adjacent intersections or even to a traffic information system that also leverages on VANET communication. Devices on each vehicle interpret the VTL messages and display the respective color to the driver. We envision the computing, communication and display device to be possible to retrofit on the existing car park, and the project will produce such devices. By providing unequivocal evidence of the envisioned approach on the mitigation of traffic congestion, its economical and environmental impact, and increased road safety, the project intends to pave the way for the adoption of EU legislation towards the equipping of all vehicles with VTL. Our project is a natural follow-up of the DRIVE-IN (Distributed Routing and Infotainment through Vehicular Inter-Networking) project, funded by the Portuguese Science and Technology Foundation and involving an international partnership with Carnegie Mellon University in the US. DRIVE-IN has been designing VANET communication protocols and developing high-scale traffic models and simulators that will support the design and validation of the in-vehicle VTL system. DRIVE-IN has also deployed a prototype VANET in the city of Porto, resorting to 450 taxis where carPCs with windshield displays are installed, together with 802.11p wifi cards for V2V and vehicle-to-infrastructure (V2I) communication. This test-bed constitutes a major asset for the research herein proposed and shall be used for proof-of-concept field experiments in closed areas of the city. The project is structured in the following four main tasks: 1 – Design of the VTL communication protocol and distributed optimization of traffic flow. 2 - Security and reliability of the VTL system. 3 - Human-machine interface of the VTL system and usability evaluation. 4 - Hardware design for retrofitting and field trial experiments. Our 41 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS team includes experienced researchers with different backgrounds, including computer science, computer engineering, civil engineering and mechanical engineering. We leverage on specific expertise in vehicular networks, intelligent transportation systems, vehicular human-machine interfaces, wireless networking security and traffic management. Acron / Ref COST IC1104 IC1104 Title ICT COST Action IC1104 - Random Network Coding and Designs over GF(q) Funding EC Descript. Random network coding emerged through an award-winning paper by R. Koetter and F. Kschischang in 2008 and has since then opened a major research area in communication technology with widespread applications for communication networks like the internet, wireless communication systems, and cloud computing. It allows transmitting information through a network by disregarding any of its topological features. As in traditional algebraic coding theory, two main research directions in random network coding are: 1- existence and construction of good and optimal network codes, 2efficient encoding and decoding schemes for a given network code. Restriction to the so-called Grassmannian codes has proven to be advantageous and leads to the theory of designs over GF(q). Worldwide, there exists a larger number of workgroups focusing on this topic, which includes several groups located in Europe. This COST Action will set up a European research network and establish network coding as a European core area in communication technology. Its aim is to bring together experts from pure and applied mathematics, computer science, and electrical engineering, who are working in the areas of discrete mathematics, coding theory, information theory, and related fields. Acron / Ref COPWIN PTDC/EEI-TEL/1417/2012 Title Coordinated MultiPoint Strategies for Future Wireless Networks Funding FCT/PTDC Descript. The main technical objectives of the project are to design, implement and validate techniques exploring BSs collaboration for future wireless systems. The aim is to design and demonstrate practical multicell transmission and reception techniques that improve user’s fairness and throughput, namely at the cell-edges. To reach the above main goals, specific research objectives are: 42 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS • Design of practical precoders for the downlink of multicell MIMO-OFDM based networks. Initially, we will focus on the intra cluster interference. Two approaches are considered: full centralized, which requires that CSI and data of all UTs are available at the CU; distributed, where the precoding vectors and power allocation are computed in a distributed fashion on each BSs. In the second phase a joint precoding approaches will be designed to remove both intra and inter cluster interference by exploiting the promising concept of IA. • Design of efficient multiuser detection techniques for the uplink of multicell MIMO SCFDMA based networks. These receivers will be implemented in the frequency-domain, based on the IB-DFE concept, eventually taking advantage of the channel decoder output. The multiuser decoder will be designed taking into account nonlinear effects in the transmission chain and can involve the estimation and cancellation of those effects. • Designing of efficient signalling strategies both for the feedback of wireless link information and distribution among the cooperating network elements, aiming to optimize the trade-off between achieved performance and signalling overhead. Moreover, particular emphasis will be placed on inter-cluster feedback and quantization strategies. • Design and optimization of medium access control protocols for the considered clustered multicell architecture with joint scheduling and dynamic link adaptation. The framework of multi-objective optimization, will be used to find the algorithms that efficiently allocate radio resources (power, carriers) among the different tiers. • Assessment and validation of the proposed downlink and uplink algorithms under realist scenarios, trough a system level simulator based on LTE specification. • Development of an FPGA based testbed allowing to experimentally show the feasibility of the proposed algorithms. The most promising algorithms (with good complexity/performance trade-off) will be integrated and characterized in this testbed. Acron / Ref mm-SatCom PTDC/EEI-TEL/0805/2012 Title Millimeter Wave Antennas for Next-Generation Satellite Mass Services Funding FCT/PTDC Descript. 1) Research of new compact Ka-band satellite antenna solutions capable of operating simultaneously in both uplink and downlink bands. The antennas will be based on the aperture overlap concept. In one approach an adequate frequency-selective multi-layer slab is placed above an array of feeds in order to produce multiple overlapping apertures, each one ensuring adequate reflector illumination. In another approach of the project, integrated shaped lens antennas with multiple feeds attached to its base will be 43 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS explored with the same objectives. 2) Design of compact low-cost Ka-band antennas for terrestrial terminals, either fixed or installed on moving platforms like cars, trains or ships. These antennas must have a single steerable beam constantly pointing towards the satellite as the terminal moves. This will evolve from a previous concept proposed by the project team, where a steerable shaped dielectric lens pivots in front of a stationary feed requiring no rotary joints which are expensive and prone to faults. New lens configurations will be researched, including flat lens made of inhomogeneous metamaterial. Acron / Ref RFMLI 4000106436/12/NL/NR Title Thermal Blanket with Low RF Reflectivity Funding HPS-Portugal Descript. The primary objective of this study is to propose a series of concepts based on metamaterials in combination with the typical materials used in thermal blankets in order to reduce the blanket’s RF reflectivity in specific frequency ranges. Concepts will be explored at the C-, Ku, Ka and Q/V bands. The new blankets are required to maintain their thermal and mechanical properties as much as possible and be designed with space flight in mind using space qualified clean-room compatible materials. Further requirements include cost effective fabrication compatibility, and reduced added mass compared to traditional multi-layer blankets. Acron / Ref TElectronics PDTC/2764/2012 Title Transformation Electronics and Optics Funding FCT Descript. We propose three major research lines: • Tailoring the electron mass and the transport properties – In a semiconductor the effective mass determines the inertia of the electron to an external stimulus. The finite value of the mobility ultimately limits the speed of integrated circuits and other devices. In most electronic circuits the electron flow is supposed to occur along a predetermined 44 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS path, e.g. down the passageway connecting two transistors. However, typically only a small fraction of the available free carriers responds effectively to an external electric field. We want to show that based on the superlattice concept it may be possible to engineer the electron mass tensor in such a way that (i) all the available electronic states contribute to the electron flow. (ii) the intrinsic electron resistance to movement is greatly reduced. In addition, these ideas may enable to boost the electrical conductivity. • Tailoring the nonlinearities in graphene and semiconductor superlattices and in electromagnetic metamaterials – Nonlinear electromagnetics (in particular nonlinear optics) has important applications in frequency multiplication or high-speed data transmission based on solitons. However, the nonlinear response of most natural materials is extremely weak. Previous studies have shown that by tailoring the electronic structure it is possible to enhance the nonlinear response. Here, we suggest boosting the nonlinear response by decreasing the intrinsic resistance of the electron to movement in engineered semiconductor or graphene superlattices. Our objective is to develop novel electronic materials with enhanced nonlinear response, and in addition to characterize the solitons supported both by these structures and by more conventional electromagnetic metamaterials based on metallic nanowire arrays. • Effective medium theory – Effective medium theories are of key importance in the study of “low energy” physical phenomena since they enable reducing the inherent microscopic complexity of a physical system to a few effective parameters. Despite the fundamental differences between photons and electrons, there are many formal similarities between photonics and electronics, which ultimately result from the waveparticle duality. However, the theoretical frameworks typically adopted to describe wave propagation in electromagnetic media and in semiconductors are usually rather different. As a generalization of our previous studies in the context of electromagnetic metamaterials, we propose to develop a general effective medium framework based on the Hamiltonian formalism that enables describing “macroscopic excitations” in both electromagnetic metamaterials and semiconductor and graphene superlattices. Such common framework will enable establishing straightforward analogies between electronics and photonics. Acron / Ref CREATION EXCL/EEI-TEL/0067/2012 Title Creation – Cognitive Radio Transceiver Design For Energy Efficient Data Transmission Funding FCT Descript. The next generation of wireless communication devices must achieve Gigabit data rates and low power consumption by making more efficient use of the radio-frequency 45 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS spectrum and taking advantage of device interoperability. To meet these requirements, the development of cognitive radio devices will be far more complex than that of their predecessors. Large, interdisciplinary development teams are required to cover areas such as analog RF hardware, digital hardware design, digital signal processing and system architecture. With the research team selected for this project we believe to have put together all the expertise required to face the design challenges of the radios of the future.

Power Amplifier Design for Space Applications based on GaN transistors Acron / Ref ADIN PTDC/EEI-TEL/2990/2012 Title Advanced PHY/MAC Design for Infrastructure-less Networks Funding FCT/PTDC Descript. This project aims to integrate MPR, IC, PHY-cooperation, CRD and AM technologies in a single architecture particularly tailored for ILWNs, which is itself a challenging task due to the lack of a central coordinator and the spatial distribution of the nodes. The main goal of the project is to investigate if the theoretical capacity of ILWNs can be achieved by practical communication systems, or at least evaluate how far an optimized solution, such as the one proposed in this project, is from the theoretical capacity bound. The communication systems’ architecture proposed for each node will be based on a crosslayering design between the physical and the MAC sub-layer. Acron / Ref COST TD1301 TD1301 Title Development of a European-based Collaborative Network to Accelerate Technological, Clinical and Commercialisation Progress in the Area of Medical Microwave Imaging Funding ESF 46 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS Descript. One of the most promising emerging medical imaging modalities is Microwave Imaging (MWI), which is a low-power, low-cost, non-ionising imaging modality and also has therapeutic capabilities. Most of this MWI research to date has been accomplished in simulation and laboratory studies, with only limited translational research into the clinical environment. European researchers have been at the forefront of the development of MWI. With respect to medical applications, these (mostly independent) efforts have lead to the design of several microwave-based imaging devices, most of which are currently undergoing or poised for clinical trials. Such a reserve of knowledge constitutes a unique opportunity for European researchers to leverage existing experience and expertise to streamline the transition from simulation/phantom testing to full clinical trials and clinical adoption of MWI devices. Collaboration will provide a valuable non-competitive framework which will provide European researchers with the necessary structure and support to overcome common challenges and bring MWI from “research bench to patient bedside” in a much shorter period of time, boosting the European Research Area and its excellence in a worldwide context. Experience in the commercial evaluation of MWI devices will also be shared amongst COST participants. Acron / Ref KALens AO/1-7493/13/NL/AD Title Compact Lens-Based Mechanically Steered Ka-Band user Terminal Antenna Funding ESA-ESTEC Descript. The main objective of the project is to develop a compact low-profile lens-based mechanically steered Ka-band antenna for satellite mobile user terminals. It is intended as a single aperture antenna to operate simultaneously in the downlink and uplink bands with circular polarization, the scanning being achieved by in-plane lens translation over a fixed feed. The pros and cons of translating the feed with fixed lens will be also addressed. Besides the feed design, it requires the identification of an adequate lens type, its fabrication technology and its design. Acron / Ref EnAcoMIMOC o EXPL/EEI-TEL/2408/2013 Title Enhanced Underwater Acoustic Receiver Design for MIMO Communications Funding FCT Descript. The underwater world offers an immense space with an enormous potential, especially for a country as is Portugal that has one of the biggest marine zones in Europe (Exclusive Economic Zone, the 3º largest in Europe and 11º largest in the world). A fundamental part for withdrawing the full potential of this natural resource is to solve the problem of 47 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS high-bandwidth underwater communications. This project aims to develop signal processing schemes that will enable for high bandwidth underwater acoustic (UWA) communications using aggregates of sources and hydrophones (Multiple Input, Multiple Output - MIMO) between mobile emitters and receivers. In radio communications, MIMO systems allows for considerable gains in the transmitted throughput and reliability, what has recently made several research groups to consider them for UWA. However, the propagation channel in UAC has characteristics substantially different than that of radio channels; since it has a high variability in both time and frequency (i.e., the channel is doubly selective). Besides that, the noise presents impulsive characteristics, for which the normal Gaussian model is inadequate. So being, the use of techniques for the normal radio channel without specific modifications would give rise to high performance degradation in UAC. This being, the main purpose of this project is to develop and assess the performance of transmission techniques for MIMO-UWA systems. The project will begin by selecting relatively simple channel models to account for the doubly selective specificities of the doubly selective UWA channel model. Adequate models to characterize the impulsive noise specifications of the channel will also be selected, in order to permit adequate analytical processing. Afterwards, special transmission techniques specially designed for MIMO-UWA will be developed. These techniques will be based on MIMO-OFDM (Orthogonal Frequency Division Multiplex) and MIMO SC-FDE (Single Carrier- Frequency Domain Equalization) [BFDT10], combined with IB-DFE (Iterative Block-Decision Feedback Equalizer) [Benvenuto_Dinis_ProceedingsIEEE2010]. The channel will be estimated by taking advantage of Delay-Doppler Spread Functions (DDSF) [ZGB10_2]. We will exploit the sparsity of DDSFs for the envisaged patterns of motion and their spatial correlation to derive fast MIMO estimation methods using basis pursuit, as well as techniques to compensate for deviations of the carrier’s frequency (CFO – Carrier Frequency Offset) [PDN10]. In the case of OFDM modulation, techniques to reduce the PAPR(Peak-toAverage Power Ratio) will be employed based on non-linear devices [DG04, DSA09], so that a greater amplification efficiency can be attained, as well as adequate receivers for non-linear systems [Guerreiro2012,Guerreiro2013]. The developed MIMO systems will be validated with realistic Matlab simulations, a program yet to be developed and adapted with blocks already implemented by the different persons of the research team. This program will serve as a demonstrator/ prototype for the project.

Even though fountain coding can be combined with collaborative network coding to reduce network overhead and improve bandwidth efficiency, there is great scope for tailoring transceiver designs to the requirements of content distribution and for developing radically new paradigms capable of supporting high quality media in next generation systems. The R2D2 project aims to: - Develop a mathematical framework to identify key relationships between various network parameters, contribute to the understanding of network dynamics and assist in the system-level optimisation of network-coded architectures. - Leverage the benefits of joint channel coding and network coding and propose joint transceiver designs for content delivery.

The main technical objectives of the project are to design, implement and validate a set of techniques that enables efficient coexistence of heterogeneous systems (macro and smallcells). The aim is to design and demonstrate practical joint cooperative and cognitive transmission/reception techniques to improve the user’s fairness and throughput of the entire network. The specific objectives include: •Design linear precoding techniques to mitigate both intra-system (on each smallcell or macro-cell) and inter-systems (smallcell/macrocell) interferences. We consider that some terminals are equipped with cognitive capabilities to efficient design the precoders, namely the ones used to mitigate the inter-system interference. •Design joint precoding and detection techniques for uplink to mitigate both intra/intersystem interferences. The aim is to combine the interference alignment with efficient equalization schemes (e.g. IB-DFE based ones). •Design efficient signaling strategies both for the feedback of wireless link information and distribution among the cooperating network elements, aiming to optimize the tradeoff between achieved performance and signaling overhead. Moreover, particular emphasis will be placed on inter-system feedback and quantization strategies. •Assessment and validation of the proposed downlink and uplink algorithms under realist scenarios, trough a multilink level simulator based on LTE specification. •Development of an FPGA based testing infrastructure allowing to experimentally show 50 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS the feasibility of the proposed algorithms.

Acron / Ref GALNC EXPL/EEI-TEL/1582/2013 Title Generalized Linear Amplification with Nonlinear Components for broadband wireless systems Funding FCT Descript. Broadband wireless systems require high power and spectral efficiencies, and transmission over severely time-dispersive channels. In this research theme we consider the design and implementation of digital transmission techniques with high power and spectral efficiency to be employed in the uplink of mobile systems or in satellite communications. We consider SC-FDE techniques (Single- Carrier with FrequencyDomain Equalization) combined with powerful IB-DFE (Iterative Block Decision Feedback Equalizer) receivers [Ben10]. Our main goal is to design signals with low PAPR (Peak-toAverage Power Ratio) or even quasi-constant envelope and high spectral efficiency and employ amplification techniques based on low-cost, highly efficient grossly NL (NonLinear) amplifiers (e.g., class D and E amplifiers), which are simpler and have higher amplification and output power than quasi-linear amplifiers [Rey06]. Two approaches will be followed. The first one uses LINC techniques (Linear amplification with Nonlinear Components) [Cox74], where a variable-envelope signal is decomposed as the sum of two constant-envelope signals, which are separately amplified without distortion by two NL amplifiers. Although LINC techniques seem an efficient solution for our problem, they have the following problems: -The power amplification efficiency reduces with the PAPR of the signals at the LINC input; -The LINC decomposition is performed on a sampled version of the signals and the oversampling requirements can be very high, mainly due to signals’ zero crossings; -The two amplifiers must be perfectly matched, since amplifiers’ unbalances lead to performance degradation and out-of-band radiation. To maximize amplification efficiency we use MM (Magnitude Modulation) techniques [Tom02, Gom09, Gom10] so as to reduce the PAPR of the signals at LINC input. Appropriate MM techniques will be developed so as to avoid zero-crossings and the IB- 51 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS DFE receiver will be designed taking into account the adopted MM schemes and eventual residual amplifier unbalances. The impact of phase and gain mismatches on performance and out-of-band radiation will be studied to define amplifiers’ matching requirements. The second approach is less orthodox and takes advantage of the following: -A given constellation can be decomposed as the sum of binary components [Din10]; -The complex envelope of OQPSK (Offset Quadrature Phase Shift Keying) signals at an appropriate frequency can be regarded as BPSK signals [Amo77]; -OQPSK signals can have quasi-constant envelope. Therefore, a given constellation can be decomposed as the sum of several constant-envelope BPSK (or OQPSK) components that can be separately amplified without distortion by different NL amplifiers, as in LINC transmitters, but without oversampling requirements. One problem with this approach is that the band of constant envelope BPSK/OQPSK signals is much wider than the minimum Nyquist bandwidth. For this reason, we replace each BPSK/OQPSK component by an OQPSK-type signal (which is also the sum of OQPSK terms) specially designed to have quasi-constant envelope and good spectral characteristics [Mon10]. This approach is suitable for somewhat loose spectral restrictions. If not, we separate different frequency channels to the minimum Nyquist band and design FDE receivers able to cope with strong ACI levels (Adjacent Channel Interference) by combining the techniques of [Din05,Luz09] with receivers specially designed for offset modulations [Mar09,Luz12]. With this approach, amplifiers’ unbalances do not lead to out-of-band radiation, however they can lead to performance degradation. The proposed techniques will be studied both analytically and by simulation, to check the potential and limitations of each one, taking into account achievable performance, spectral efficiency robustness and complexity issues. The main contributions of this project are the following: -Design of OQPSK-type signals with quasi-constant envelope and good spectral characteristics; Design of MM schemes specially designed to be combined with LINC-type techniques, namely to reduce the oversampling requirements; -Design MM schemes for offset modulations and different pulse shapes; -Design of linear amplification schemes for general constellations that employ multiple (more than two) grossly NL amplifiers; -FDE design of MM and OQPSK-type schemes, with or without ACI, eventually taking into account residual amplifiers’ mismatches; -Definition of matching requirements for multiamplifier techniques; -Validation and system simulation for most promising techniques; Acron / Ref L-DimM-NetCod P1275 Title Large-Dimensional MIMO Physical Layer Network Coding Funding IT/LA Descript.

Acron / Ref MEMCOPAs EXPL/EEI-TEL/0851/2013 Title Memory-Effects Compensation in GaN Power Amplifiers Funding FCT Descript. Nowadays, it is unquestionable that communication systems play a very important role in our daily routine. Wireless systems, in particular, are growing in such a way that people have difficulty living without the services already available. This being the case, any big change, or improvement, in terms of power consumption in these systems will certainly have a big impact on what the available resources usage is concerned. Moreover, it is not acceptable that technology uses more and more resources in an unthinkable way without trying to be as efficient as possible. This project comes exactly in this direction as it tries to push further state-of-the-art systems that, unfortunately, have their own problems inherent to their infancy. Having that in mind, this project is focused on the design and implementation of a memory-free wireless transmitter built with GaN transistors. It is undeniable that this technology was a breakthrough in what efficient and available power are concerned. Unfortunately, it still suffers from several 53 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS problems that are yet to be solved. Therefore, the above referred main objective of this project can be tackled according to the following different, but interrelated, goals: (i) It is recognized that, for understanding something in nature, first we need to carefully characterize it. In what memory-effects in GaN transistors are concerned the methodology has to be the same. So, the objective is to fully characterize them using a set of reference measurements such as: - static and dynamic AM/AM and AM/PM amplitude sweeps; - step-up and step-down output power and phase measurements going from small- into large-signal regimes; - S-parameters for the bias circuitry and matching networks characterization. (ii) Modeling memory-effects in commercial computer added design simulators making it possible to replicate, in a virtual environment, the real operation of the device and search, in a more flexible way, for the necessary solutions. (iii) Correct the memory-effects (short- and long-term) visible in todays’ power amplifiers and prove it with a complete prototype implementation.

The integration of the existing IF stage into a highly scalable RF stage would represent an incremental step and also a strategic extension of the RF measurement facilities available at IT, particularly for a multi-frequency measurement system capable of measuring channel impulse response, in addition to the dynamic effects, including Doppler spectra for each individual multipath component, of doubly selective propagation channels. The proposed topology for the channel sounder has the portability to be quickly and easily re-located to various measurement sites, as well as the flexibility to characterise a wide variety of frequencies, e.g. 18, 37 and 61 GHz.

Mobile networks are subject to an explosive increase in use, focusing on video and multimedia services, in a context of continued mobility, which imposes requirements to telecommunication networks in order to withstand this type of use, without any decrease on quality of service experienced. In order to ensure these requirements, the IT sector is developing mobile networks, mainly on the mobile segment, based on the increase of radio cells which will tend to be smaller in a coverage sense (small cells). On the other hand, in an attempt to maximize the utilization of network resources while 58 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS minimizing power consumption, the concept of ''Cloud RAN'', an architecture in which the component BBU (Base Band Unit) is shared by several RRH (Remote Radio Heads) is starting to be thinking off. This architecture will further re-use the resources, by allowing the BBU to be simultaneously used and to support various access technologies (2G, 3G and 4G). This functionality is achieved through the use of specific protocols, including CPRI and ORI. Although there is an evolution in network optimization with C-RAN, currently, looking ahead in order to go even further, network optimization can be promoted with the use of metro and access networks, including fixed ones (including SOPs) to support mobile backhaul networks. In order to overcome CPE/RRH current limitations, PT INOVAÇÃO and IT are launching this project that faces the challenge of joining the concepts of ''Small Cell'', ''Cloud RAN'' and ''infrastructure sharing'' in an integrated and unified architecture.

Acron / Ref WINCE C00356 Title Wireless Interference and Coding for Secrecy Funding IT/LA Descript. The main goal of this project is to advance the state-of-the art on physical-layer techniques to secure wireless networks under eavesdropper adversaries that aim to overhear unintended information. The almost-permanent connectivity of people and things to the Internet that we are currently approaching poses several security and privacy challenges, such as how to assure confidentiality in spontaneous networks of unknown users/devices, where key-exchange is deemed difficult. Physical-layer security is gaining interest as a means to provide an extra layer of security that does not depend on the traditional cryptographic key-exchange, but takes advantage of the inherent varying characteristics of wireless channels to establish secure communication. In this work, we plan to develop, implement and evaluate practical physical-layer security techniques based on coding and spread spectrum methods. In particular, we plan to develop interleaving for secrecy mechanisms, where the access to a degraded version of the interleaving key acts as the source of advantage over an adversary eavesdropper. Moreover, to provide periods of advantageous communication for interleaving key exchange, we shall develop spread spectrum frequency-hopping mechanisms combined with jamming over eavesdroppers and tailor the operation of such mechanisms to provide the highest possible advantage over the eavesdropper. The developed 60 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS techniques shall form the basis for more evolved physical-layer security schemes, such as combined with cognitive radios – intelligent radio interfaces that can be programmed and configured dynamically to react more intelligently to environment changes – to enable embedded security services in the next generation of spectrum efficient wireless networks.

Acron / Ref SPEED-5G Title SPEED-5G Funding EU Descript. The objective of SPEED-5G is to research and develop technologies that address the wellknown challenges of predicted growth in mobile connections and traffic volume. A major challenge is the cost of meeting the objective, in terms of both infrastructure and deployment. Today, lack of dynamic control across wireless network resources is leading to unbalanced spectrum loads and a perceived capacity bottleneck. These will be solved by SPEED-5G through eDSA (extended DSA), which is resource management with three degrees of freedom: densification, rationalized traffic allocation over heterogeneous wireless technologies, and better load balancing across available spectrum. SPEED-5G will investigate indoor and indoor/outdoor scenarios where capacity demands are the highest, but also where the eDSA will be the most effective at exploiting co-operation across technologies and bands. The project will focus on two major innovations which are currently missing: resource management techniques across technology ‘silos’, and medium access technologies to address densification in mostly unplanned environments. It will leverage flexible radio approaches expected in 5G (e.g. FBMC). SPEED-5G has a very strong consortium, with a mix of operators, industrial partners, SMEs and leading European research institutes. They bring considerable knowledge and technology background to the project in architecture, resource management, protocols, radios, standardization, trials and tests, along with the most advanced of trial facilities, like the 5GIC centre. The SPEED-5G innovations will be considered in an architectural framework consistent with the 5GPPP. They will be researched, implemented and trialled in SPEED5G in order to reach high level of maturity and confidence.

In this work we used a homemade Finite Difference in the Time Domain (FDTD) algorithm to characterize the propagation of electron waves in graphene. The algorithm was applied to study the dynamics of electrons in graphene superlattices, using both microscopic and 102 ANNUAL REPORT 2015 – WIRELESS COMMUNICATIONS effective medium approaches. In particular, it is shown that the time evolution of an electronic state and the propagation of stationary electronic states may be accurately predicted with the effective medium formalism, provided the initial state is less localized than the characteristic spatial period of the superlattice. Our results confirmed that electrons propagating in graphene superlattices with extreme anisotropy experience virtually no diffraction, 01-12-2015 Cunha, TC; Vieira, P.; Martins, A.; Energy Savings in 3G Using Dynamic Spectrum Access and Base Station Sleep Modes, URSI Atlantic Radio Science Conference - URSI AT-RASC , Maspalomas , Spain , Maio de 2015 (2nd Place, Best Student Paper Contest), 01-05-2015 Pedro, J.

The security of this protocol is based on the lack of long-term stable quantum memories. We used a polarization-encoding scheme and optical fibre as a quantum channel. The measurement probability for the commitment is obtained and the optimal cheating strategy demonstrated. Using a strict numerical validity criterion, we show that, for the obtained experimental values, the protocol is secure. 4.2.3.1.2 Numerical modeling and simulation • • Modeling of concentrating photovoltaic-thermal (PVT) using LTSPICE program has been accomplished. The effects of partial shading of cell strings and temperature have been analyzed, showing very good agreement with the results obtained experimentally either in the lab or under outdoor testing using similar receivers. The methodology for the design of the solar cell configuration has been emphasized as an important tool to optimize PV and PVT performances in the energy conversion process. The model has been used for a comparative analysis of several configurations of the string of cells of manufactured PV modules, in order to improve their efficiency. The numerical analysis and modeling of ultrafast, long wavelength semiconductor photodetectors for optical communication systems continued. The work was focused on pin based devices namely waveguide photodetectors.

Work on plastic optical fibres (POF) included: modelling and improvement of the theoretical understanding of new geometries of POF; fabrication of plastic fibre Bragg gratings with different geometries. Development of a new technique for splicing of POFs using the selfwritten waveguides approach. We developed an experimental setup for electromagnetically induced transparency able to manufacture microcells, suitable for optical fibre communications technology. A hollow-core photonic crystal fibre (HC-PCF) is filled with acetylene, to work in the 1500 nm telecommunications window. We used a HC-PCF with the mode-field diameter compatible with standard single-mode fibres with the purpose of achieving low-loss splicing and enabling us to work at low pumping powers. This allows to induce a narrow transparency window, which can be spectrally adjusted and dynamically controlled. 4.2.3.1.4 All optical signal processing • • We proposed a new method to design and produce periodically poled lithium niobate (PPLN) waveguides with custom spectral response to enable new features and possibilities for PPLNbased optical signal processing, showing an excellent agreement between the target and experimental spectral response of the produced devices. We showed advanced tunable and multichannel wavelength conversion in a single PPLN waveguide device, as well as phase noise tolerant wavelength conversion and wavelength exchange of data channels using advanced modulation formats to encode the information. Furthermore, we proposed a new scheme based on bi-directional propagation in a single PPLN waveguide to simplify the implementation of phase-sensitive amplifiers. Using such amplifier, we showed effective all-optical phase regeneration of degraded phase-modulated data channels. 111 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS 4.2.3.1.5 Sensors There was an intense research on fibre and free space optical sensors. The parameters range from displacement, level, temperature, pressure, refractive index, strain, chemical, and biological parameters. The main research topics were: • • • • • • • New coatings to improve performance or add new functionalities. The coating of the optical fibre with carbon allotropies, namely diamond and graphene oxide was a procedure used to improve the performance of sensors. In addition, novel chemical optical fibre sensors for water quality assessment using molecular imprinted polymer (MIP) technology were developed. Fibre Bragg Gratings (FBGs) in plastic fibres, including smart textile with embedded Polymer fibre Bragg gratings (PFBGs) High temperature sensors using regenerated FBGs. Another technique involved the production of Bragg gratings resistant to high temperatures, namely regenerated Bragg gratings to monitor the sintering process of porcelain tableware. Several cost effective optical fibre sensors were developed, based on Fabry Perot Interferometer (FPI) micro cavities created by the catastrophic fuse effect. The parameters monitored were refractive index, strain, high temperatures, relative humidity and liquid hydrostatic pressure. Application of sensors to monitor different processes, such as injection moulding process, monitoring of the dynamic behaviour of shape memory polyurethane composites. Development of new optical sensing solutions to be implemented in the next generation of rehabilitation exoskeletons. Development of a Mach-Zehnder interferometric sensor to monitor the refractive index of biological samples and the synthesis and characterization of thin films of sol-gel hybrids doped with electro-optic active molecules. 4.2.3.2 Optical communications systems 4.2.3.2.1 Signal processing for high-bit rate optical communications • • We proposed a novel closed-form time-domain (TD) Volterra series nonlinear equalizer (VSNE) for the mitigation of Kerr-related distortions in polarization-multiplexed (PM) coherent optical transmission systems. In order to enhance the computational efficiency, we insert a power weighting time window in the TD-VSNE, yielding the weighted VSNE (W-VSNE) algorithm. Through numerical simulation of a 224-Gb/s PM-16QAM optical channel, we compared the performance/complexity trade-off of the W-VSNE with the well-known split-step Fourier method (SSFM) and with the computationally optimized weighted SSFM (W-SSFM). The W-VSNE achieved a reduction of up to∼45% on computational effort and ∼70% on latency, in comparison with the W-SSFM. We demonstrated fully blind processing and reduced complexity nonlinear equalization (NLE) of a 100G PM-64QAM optical channel in a 50 GHz WDM grid, achieving a maximum reach of 1524 112 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS • • km over pure silica core fibre at a bit error rate of 2.7 × 10−2. Applying a simplified Volterra series nonlinear equalizer (simVSNE), operating in the frequency domain, we demonstrate a reach extension of ∼27% relatively to linear equalization. We studied experimentally an adaptive polarization demultiplexing (PolDemux) technique. The applicability of the adaptive Stokes algorithm was tested in an ultra dense wavelength-division multiplexing scenario over 80 km of standard single-mode fibre. The BER results showed a very small power penalty confirming the suitability of the adaptive Stokes method in systems where the accumulated chromatic and polarization-mode dispersion are small, such as high capacity optical metro and access networks scenarios. We applied an extended Kalman filter to Stokes space-based polarization demultiplexing for complex-modulated signals. The convergence ratio, tracking, computational complexity, and system performance of this method were investigated and compared with the geometrical approach previously proposed. An analysis of the tuning parameters of both methods reveals that the Kalman filtering provides a more robust and stable polarization demultiplexing of signals. Nevertheless, if properly tuned, the geometrical approach attains a similar performance, with a gain of 90% in terms of complexity reduction 4.2.3.2.2 Performance evaluation of optical communication systems and networks • • • • • • • • • Investigation of degradation of performance on optical single sideband signals in case of direct detection.

Generalization of the rigorous formulation to consider the impact of homodyne crosstalk from optical network elements on OFDM optical communication systems. Evaluation of the impact of in-band crosstalk on OFDM optical communication systems using a simplified approach Evaluation of the impact of in-band and coherent crosstalk in optical coherent QPSK systems using an analytical model based on the moment generating function of the receiver decision variable. Development of an analytical model to characterize the impact of the phase-to-intensity conversion of the laser phase noise, due to the optical band selector (BS) used for band extraction, on the performance of DD optical MB-OFDM networks employing single-sideband (SSB) modulation. By considering adaptive bit loading (ABL) and band loading (ABnL), the maximum capacity of ultra-dense MB-OFDM systems, employing virtual-carrier assisted DD, was evaluated for different scenarios and compared with uniform modulation (UM). 113 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS • An ultra-dense 100-Gb/s multi-band orthogonal frequency division multiplexing (MB-OFDM) system employing virtual-carrier-assisted direct-detection (DD) and a 2.85-GHz receiver bandwidth was demonstrated experimentally. 4.2.3.2.3 Radio over fiber systems • • • • Investigation of RoF transmission using directly modulated lasers. Power optimization of OSSB modulation to support multi-band OFDM services along hybrid long-reach WDM-PONs. Mitigation of nonlinear impairments in a RoF link based on OFDM signal transmission by direct modulation of a VCSEL; Microwave photonic technology to support 100 Gbit/s for wireless links operating in the W band. 4.2.3.2.4 Optical transmission based on space division multiplexing • • • • • • Investigation of the use of multi-band OFDM signals in multicore fibers to reduce inter-core crosstalk Study of time and modulation frequency dependence of crosstalk in homogeneous multi-core fibers. Evaluation of the impact of inter-modal four-wave mixing and inter-modal cross-phase modulation on the performance of mode- and wavelength-division multiplexing systems. Mode-division multiplexing requires all-optical signal processing techniques that are able to deal with a new coding dimension, the spatial mode. In this context, optical micro wires emerge as a potential highly non-linear and multi-modal waveguide for all-optical signal processing devices to be used in mode-division multiplexing systems based on the four-wave mixing process. The inter and intramodal phase-matching conditions for the four-wave mixing process were mapped as a function of the micro wire diameter and the wavelength of signals. Moreover, the efficiency of four-wave mixing considering a strong guiding regime was investigated in the multi-modal regime. We proposed an in-line wavelength selective core switch for multicore fibre (MCF) transmission systems, based on the acousto-optic effect. A theoretical model addressing the interaction between flexural acoustic waves and the optical signal in MCFs was developed. We showed that an optical signal propagating in a particular core can be switched to any other core or distributed over all the cores. By tuning the acoustic wave amplitude, we can adjust the amount of optical power transferred between the cores. We studied theoretically and experimentally the viability of using Long Period Gratings (LPG) in multicore fibres (MCFs) as a solution to develop different components. We proposed the use of identical LPGs inscribed on a four-core fibre to promote the power transfer between all the cores evenly, which can be used to distribute a single pump to all the cores. We also studied the power transfer between identical cores of heterogeneous MCFs as a first step towards the 114 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS realization of an inline core/wavelength selective switch for MC space division multiplexed transmission systems. 4.2.3.2.5 Digital signal processing for optical communication systems • • • 4.2.3.3 Assessment of the mitigation of the signal-signal beat interference in 112 Gb/s MB-OFDM systems employing a digital post-distortion (DPostD) algorithm based on memory polynomials (MP). We analyzed the performance and the complexity of a real-time digital signal processing (DSP)based optical network unit architecture for the digital detection of Nyquist-shaped signals in ultra-dense wavelength-division multiplexing passive optical network (UDWDM-PON) scenarios. Using field-programmable gate array-based 8-bit DSP, we experimentally demonstrated in a real-time mode operation the receiver performance in terms of Nyquist filter roll-off factor for 8×2.5 Gb/s quadrature phase-shift keying (QPSK) with 2.5 GHz of channel spacing. We analyzed the performance of the linear and cubic interpolation for the clock recovery as well as the Gardner algorithm for the timing-error estimation, considering the amplitude and power formulations. The experimental evaluation shows that the linear interpolation along with the power formulation is an attractive solution for the QPSK-based UDWDM-PON, considering the trade-off between the performance and the complexity. Optical networking 4.2.3.3.1 Optical transport networks • Defragmentation techniques for optical networks: development of integer linear programming techniques and heuristics to optimize optical networks using defragmentation techniques • Flexible-grid optical networks: development of a multi-period planning methods to optimize the allocation of transponders, client cards and switches in optical translucent networks. • Comparison via network simulation of different strategies for the placement of a limited number of pre-deployed 3R regenerators in DWDM transport network operated dynamically or quasidynamically. • Development and implementation of a framework for the cost-optimized design of fixed- and flex-rate line-cards and transceivers over multiple planning cycles of a DWDM network. • Study of the impact of superchannel deployments in DWDM networks with legacy wavelength services. • Investigation and performance comparison of different node architectures for multi-layer (OTN / DWDM) networks. • Evaluation of the impact of optical node architecture on network scalability and flexibility. • Network planning challenges with next-generation transponder technology. • Evaluation of the impact of in-band crosstalk on colorless, directionless, contentionless (CDC) ROADM-based flexible grid optical networks. • Study and implementation of wavelength assignment algorithms for dynamic optical networks that take into account the impact of homodyne crosstalk. 115 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS • • • We analyzed the capital expenditures (Capex) and operational expenditures (Opex) related to the power consumption and footprint requirements of fixed and flexible node architectures in a multiperiod scenario and under different traffic requirements. Results show that in spite of the initial higher investment required by flexible architectures, in the long term they tend to present lower Capex and Opex. We proposed new dimensioning models for transport network nodes taking into consideration the multiplexing/grooming architecture. Using the developed models, we analyzed the impact of node architecture flexibility in the number of line interfaces required, and assessed the potential savings attained by exploiting hitless re-grooming. Results show that enhanced flexibility produces more savings when the client traffic bit rate is much smaller than the line bit rate. We analyzed the shortest path lengths between node pairs of real optical transport networks. From the analysis, we found that Johnson SB distribution is suitable for the shortest path length modelling. We also showed that the key parameters of the shortest path lengths, such as the mean, the median, and the standard deviation, can be estimated from the convex area of the network. It is noteworthy that these estimations can be made without full knowledge of the network. Only the node locations are required. 4.2.3.3.2 Optical access networks • An ultra-dense MB-OFDM passive optical network (PON) with a dedicated band capacity per user of 2.5 Gb/s or 10 Gb/s was demonstrated experimentally. • A new technology for flexible optical access networks (OANs) was developed. This is based on real-time digital signal processing (DSP) supported by commercial FPGAs (Field-programmable gate arrays). The new technology aims to upgrade future OANs and uses the concept of UDWDM (Ultra Dense Wavelength Division Multiplexing) based on coherent detection. The concept aims at extending the number of users of the NG-PON2 (Next Generation Passive Optical Networks 2) technology, increasing also the data rate up to at least 2.5 Gbps dedicated per end-user in the downstream and upstream directions. • A new paradigm for future OANs has been demonstrated in a field-trial, where multiple existing PON technologies (including the new NG-PON2 technology) coexisted with the new UDWDMPON technology. This experiment was validated in real-time in September 2015, with an installed network between IT-Aveiro and PT Inovação building. An aggregate data rate of 320 Gbps in realtime was demonstrated. This network can be easily extended to Tbps data rates in real-time. This field-trial was reported as a Postdeadline Paper on the largest European optical communications conference, ECOC, validating the significance of this achievement. 116 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS 4.2.4 Running and Concluded Projects Overview Funding Agency Number EC/FP7 1 ESF/COST 2 FCT 2 FCT/COMPETE/FEDER 1 FCT/PTDC 3 IT/LA 3 Activity in Projects Acron / Ref IC1101 IC1101 Title COST IC1101 - Optical Wireless Communications - An Emerging Technology Funding ESF/COST Descript. Wireless transmission via optical carriers opens doors of opportunity in areas as yet largely unexplored. Offering significant technical and operational advantages, optical wireless communication (OWC) can be, in some applications, a powerful alternative to and, in others, complementary to existing radio frequency (RF) wireless systems. Variations of OWC can be employed in a diverse range of communication applications ranging from very short-range (on the order of millimetres) optical interconnects within integrated circuits through outdoor inter-building links (on the order of kilometres) to satellite links (larger than 10,000 kilometres). In many respects, OWC research is still in its infancy and calls for extensive research to begin to harness the enormous potential of the optical spectrum. This COST Action will serve as a high-profile consolidated European scientific platform for interdisciplinary OWC research activities, spanning from characterization of diverse propagation media to modeling, design and development of devices, components, algorithms/protocols and systems. It will make significant contributions to the fundamental scientific understanding, technical knowledge, engineering design and applications while promoting community awareness of this emerging field. Development of novel and efficient communication technologies resulting from integrated research activities made possible through this Action will be a significant enabler for future-generation heterogeneous communication networks supporting a wide range of wireless services/applications. 117 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS Acron / Ref MORFEUS PTDC/EEI-TEL/2573/2012 Title Metro Networks Based on Multi-Band Orthogonal Frequency-Division Multiplexing Signals Funding FCT/PTDC Descript. The general objective of this project consists in demonstrating the new paradigm related to the increase of the flexibility and granularity of the transmission capacity in metropolitan (metro) optical networks. Particularly, the implementation of metro networks based on high data-rate multi-band orthogonal frequency-division multiplexing (MB-OFDM) signals employing wavelength division multiplexing (WDM) is analysed and demonstrated as an excellent solution to provide, simultaneously, high flexibility in capacity allocation, high spectral efficiency and the possibility of upgrading the network capacity while keeping the system architecture almost unchanged. Recently, optical transmission systems with high capacity granularity have been appointed as the most promising solution to be employed in the integration of the metro and access networks in a single hybrid optical network. Systems based on MB-OFDM signals have been recognized as an excellent solution as they allow the integration of several final users who usually require a capacity quite below the total network capacity. This access technology has been indicated as a good alternative to the solutions based on timedivision multiplexing currently deployed. Previous works have experimentally shown the dynamic allocation of OFDM subcarriers or individual bands of MB-OFDM signals as an excellent solution to increase the granularity of capacity allocation. However, these works were presented as a proof-of-concept: the MB-OFDM transmission impairments and the traffic allocation optimization were not analyzed. In addition, the main performance limitations were not identified as well. This project has two particular objectives. First, it is focused on the investigation of the performance impairments imposed by the physical layer on the high data-rate (maximum bit rate of 40 Gbit/s per wavelength) MB-OFDM signals transmission in WDM metro networks and on the system parameters optimization using analytical, simulation and experimental work. Particularly, the study and the assessment of the main system impairments is performed, such as: (i) linear crosstalk associated with the MB-OFDM transmission and with the finite selectivity of the optical devices required to select the different bands and wavelengths at each node of the metro network, (ii) linear and nonlinear fibre effects, (iii) joint nonlinear effect introduced by the electro-optic and opto-electric conversion processes. Second, this project is focused also on the study of the network layer of WDM metro networks based on MB-OFDM signals. Particularly, the assignment of OFDM bands and wavelengths, and the traffic distribution along the network are analysed. Routing, wavelength and band assignment (RWBA) algorithms are developed based on maximum wavelength and band reuse in MB-OFDM metro networks. These algorithms are developed considering the impairments imposed by the physical layer of the WDM MB-OFDM metro network (cross layer design). The work to carry out along this project is 118 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS focused on MB-OFDM signals with intensity modulation - direct detection (IM-DD) systems for transmitter and receiver cost reduction, an imperative of metro networks. Different MB-OFDM transmitters are analysed, e. g. MB-OFDM transmitters using single sideband modulation implemented using appropriate (I,Q) modulators or the generation of electrical MB-OFDM signals with adequate properties to provide strong robustness to fibre dispersion induced power fading. The ultimate goal of the project consists in the experimental demonstration of the simultaneous transmission of, at least, three optical channels using MB-OFDM signals in a metro optical network with insertion/extraction capabilities at the OFDM band level.

Acron / Ref DiNEq PTDC/EEI-TEL/3283/2012 Title Digital Nonlinear Equalization in Very-High Speed Coherent Optical Transmission Systems Funding FCT/PTDC Descript. The exponentially growing traffic demand in optical core networks has exhausted the single-mode fiber capacity within the linear regime. We aim to develop efficient digital equalization strategies in order to counteract the signal distortion imposed by fiber nonlinearities, in very-high speed (>= 100 Gbit/s/ch) and ultra-dense (>= 4 bit/Hz) multiwavelength coherent optical transmission systems. Building on our previous work and experience on this topic, we aim to optimize some of the currently proposed algorithms, mainly in terms of computational requirements, and to develop new solutions for nonlinear digital equalization in optical fiber systems. Our efforts include the extension of nonlinear equalization to polarization-multiplexing and WDM transmission. We will 119 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS focus a great deal of our attention into the problem of inter-channel nonlinear equalization, developing efficient and moderate complexity techniques to partially mitigate cross-phase modulation (XPM) and four-wave mixing (FWM) distortions. We plan to develop simplified approaches to enable adaptive equalization of XPM resorting to either blind or data-aided equalizers. We also plan to explore artificial neural networks (ANN) techniques for fiber impairment mitigation. Given the hardware implementation advantages of ANNs due to their inherent parallel nature, we expect to obtain efficient real-time implementation solutions. During the last couple of years, the interest on few-mode fibers (FMF) and mode-division multiplexing (MDM) has exploded, with numerous publications in major international conferences and journals. This sudden revival of multi-mode signal propagation is closely related with the need to reduce the effect of fiber nonlinearities, which is thereby achieved by increasing the fiber core area. From the digital signal processing (DSP) point of view, the adoption of MDM requires an extra effort to implement multiple-input-multiple-output (MIMO) equalization of intermodal transmission and coupling. Although signal impairments in FMFs are currently assumed to be mostly caused by linear processes, some pioneering works are already exploiting the impact of nonlinearities in FMFs. A timely development of nonlinear equalization techniques for MDM signal transmission is therefore of utmost importance. Within this topic there are still many problems to be tackled, ranging from development of modeling numerical tools for nonlinear signal propagation to the development of lower complexity digital equalization techniques. We propose to exploit the reported potentialities of the Volterra series transfer function, extending its scope to MDM transmission, therefore providing a powerful numerical tool for the analysis and compensation of inter-modal nonlinearities. The development and optimization of digital equalization algorithms must be accompanied by meaningful assessment through simple and accurate figures of merit. We propose to develop simple figures of merit for BER gain and required computational effort for nonlinear equalization algorithms under different propagation conditions. These figures of merit should guide the development of new equalization algorithms and the design of new very high-speed and ultra-dense transmission systems. Finally, we aim to finalize this project with an experimental test and validation stage, composed by two implementation phases: offline validation of the proposed algorithms recurring to experimental data, and hardware implementation in a field programmable gate array in order to test real-time operation. This implementation stage will benefit both from IT facilities and expect investment in coherent optical systems and from a well-established international cooperation with top-level European laboratories. Given the current absence of feasible solutions for the equalization of critical nonlinear fiber impairments, we will have the opportunity to generate crucial contributions to the state-of-the-art of coherent optical systems. In fact, solving the nonlinear limitation on fiber capacity has been identified as one of the key scientific breakthroughs to enable future Terabit optical channels. 120 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS Acron / Ref ONECI PTDC/EEI-TEL/3303/2012 Title ONECI - Optimizing Next-generation Elastic Core Network Infrastructure Funding FCT/PTDC Descript.

Acron / Ref MP1205 MPNS COST Action MP1205 Title COST Advances in Optofluidics: Integration of Optical Control and Photonics with Microfluidics Funding ESF/COST Descript. The aim of this COST Action is to establish active interlinks between laboratories working in the fields of micro and optofluidics, optical tweezers, nanoscience and photonics, bio and soft materials, focusing their work towards lab-on-a-chip systems and at promoting long-term development of these fields in Europe.

In order to capitalize on recent achievements and go one step forward, a 121 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS platform as a COST Action, promoting interdisciplinary activities, is a relevant tool to exchange expertises and to explore new opportunities coming from each specific insights and knowledge.

Single-mode fiber (SMF) transport systems are rapidly approaching the Shannon´s limit,pointing to fiber capacities of no more than 100 Tbit/s, corresponding to filling the C and L EDFA bands at a spectral efficiency of 10 bit/s/Hz. This limit can be derived from an extension of the Shannon capacity limit to a nonlinear fiber channel, since the fiber Kerr nonlinearity leads to distortion when the signal power is increased to achieve sufficient Signal-to-Noise Ratio, the ultimate limit resulting from the interaction between amplified spontaneous emission and nonlinearity, which is not deterministic. This may still be not be enough to answer the capacity requirements in the near future which points to spectral efficiencies of 20bit/s/Hz over ~1500 km links, associated with the current growth in capacity of fiber-optic communication systems. Over the last decades, the steady progress in optical transmission systems was enhanced by the exploitation of the several properties of electromagnetic waves, namely time, phase, frequency and polarization. Since 2010, the research community has generally agreed that optical transport systems will have to resort to the last remaining physical dimension (space) by employing spatial division multiplexing (SDM), which has the potential to substantially increase optical transport capacities. Although SDM was first proposed in 1979 (considering MCF) and 1982 (considering MMF), the current progress is occurring now due to a convergence of technological capabilities (fiber fabrication methods, mode control and analysis methods, coherent detection and digital compensation) and the mentioned emerging necessity. The main challenge in SDM occurs due to crosstalk between pathways, which is typically small for MCF and high for MMF. For MCF the crosstalk depends on core number, spacing and arrangement, while for MMF the modes are prone to randomly couple during propagation, with different differential mode group delays (DMGD). This requires multiple-input multiple-output linear equalization techniques, similar to the signal processing techniques used for polarization demultiplexing, which poses computational complexity concerns when considering equalization for long haul mode division multiplexed (MDM) systems. However, similarly 122 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS to SMF based modern telecommunication systems, the nonlinear penalties in MDM systems will eventually become the ultimate limiting factor. In this project we propose to explore the concept of phase conjugated twin waves (PCTW) in SDM optical systems, which has recently been proved to cancel out signal-to-signal nonlinear interactions in single-mode fibers by coherently superimposing of a pair of phase-conjugated twin waves, as a means to overcome the nonlinear impairments arising in mode division multiplexed systems, in a practical and sustainable way, paving the way for optical transmission capacities beyond next-generation systems.

Acron / Ref BEACON 607401 Title ScalaBle & Low-Power Microwave Photonics for FlexiblE, TerAbit Telecom Payloads & High-speed Coherent Inter-satellite LiNks Funding EC/FP7 Descript. Telecom satellites are growing like giants employing multiple beams to provide high speed connectivity and broad coverage. Under exploding capacity requirements, vendors admit that a technology and payload architecture switch is mandatory. The new technology has to deliver practical, low-power and scalable components with high performance under harsh environment conditions. BEACON aims to provide this technology and disrupt the transition to multibeam Tb/s satellites. Addressing cost, performance and volume, BEACON invests on the right mix of 3 photonic technologies used in terrestrial telecommunications, i.e. GaAs, Si and doped fibres and combines them to deliver a compact optical beam-forming technology delivering the massive amount of bandwidth. BEACON develops ultra-linear GaAs Mach-Zehnder Modulators (MZM) exhibiting >75dB spurious free dynamic range, 15dB higher than conventional MZMs. MZMs will exhibit: up to 35GHz frequency operation matching Ka-band frequency plans and 1/2 the size of mainstream LiNbO3 MZMs. 6’’ GaAs wafers enable high volume production. BEACON integrates and co-packages 4xMZM arrays with new packaging method. BEACON develops the first scalable multi-core rad-hard erbium doped optical fibre amplifier (EDFA). The EDFA employs new radhard doped microstructured fibre and enabling: >50% electrical power consumption reduction than using conventional EDFAs and small form factor packaging. BEACON integrates an innovative photonic beamformer (BFN) using CMOS compatible silicon photonic fabrication together with Ge diodes. The BFN chip consumes <7.5-times less chip area than lowindex contrast BFNs. It allows 4 orders of magnitude faster beamsteering. BEACON integrates the system with BFN control and antenna array to demonstrate that the technology can scale to Tb/s capacities with considerable savings in size/power against current kW consuming systems. Component space assessment will guide the 124 ANNUAL REPORT 2015 – OPTICAL COMMUNICATIONS technology towards fully space qualified systems.

This report follows the lines of basic concepts (Information and network theory; security); multimedia technologies (interactive multimedia, multimedia signal processing, and pattern analysis), communication systems (networks and protocols, mobile networks, information technologies) and finally hardware realization. 4.3.3.1 Contributing Groups The groups that contributed to this report are: • Embedded Systems – Aveiro Information Technology - Lisboa • Information Theory – Porto Interactive Multimedia - Porto • Multimedia Signal Processing – Coimbra • Multimedia Signal Processing – Covilhã • Multimedia Signal Processing – Leiria • Multimedia Signal Processing – Lisboa 156 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA • Network Architecture and Protocols – Lisboa • Network Architectures and Protocols – Aveiro • Network Architectures and Protocols – Covilhã • Networked Systems – Porto • Pattern and Image Analysis – Covilhã • Pattern and Image Analysis – Lisboa • Security and Quantum Information –Lisboa • Telecommunications and Networking – Aveiro 4.3.3.2 Information and networking theory The activities on the field of information and networking theory cover a large set of aspects. 4.3.3.2.1 Information theory Several strand were pursued here: − Combination of logics: substantial advances in the understanding of fibred logics were achieved, obtaining full characterizations of conservativity and decidability preservation results in the disjoint case, and several partial results in the general case, namely using appropriate notions of translation − Compositional meaning in logic: suitable generalized notions of compositional meaning in logic were explored, namely in the context of non-deterministic logical matrices, and obtained several new characterization − Computation with real numbers and complexity: the physical measure associated to the (geometric) Lorenz attractor was shown to be computable, as well as how computational complexity can be properly defined over analog models of computation like Shannon's General Purpose Analog Computer. 4.3.3.2.2 Complex Networks Work in this area covered: − Theoretical and experimental study of complex networks’ design, structure and dynamics with a focus on its impact on resilience and robustness properties. − Study of emergent structures in social conflict scenarios, with applications on a testbed for the simulation of confrontation with network effects. − The formulation of a theorem that equates the correctness of routing vector protocols, such as 157 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA BGP, to a property of routing policies around the cycles of a network and its application in the derivation of guidelines for the configuration of routers. − Development of a unified framework to reason about link-state routing protocols, such as OSPF and IS-IS. 4.3.3.2.3 Global Navigation Satellite (GNSS) Several research activities were developed in the area of signal processing for GNSS receivers, covering new algorithms for the detection of interference (non-intentional and jamming) in GNSS, and algorithms for the efficient simulation of Ionospheric Scintillation effects in GNSS signals. 4.3.3.3 Theoretical and Applied Security The area of security has seen large developments in the last years inside the line of Networks and Multimedia. 4.3.3.3.1 Criptography and quantum information Work was developed on Bit-string oblivious transfer (addressing a quantum computationally secure protocol for bit-string oblivious transfer between two parties); Blind signatures and PK (quantum blind signature perfectly secure, and a quantum public key cryptosystem); and quantum multiparty dense coding (allowing the sharing of information among several quantum agents). 4.3.3.3.2 Security foundations Theoretical work has obtained decidability and complexity results for an equational-based probabilistic logic, and started exploring a related NP-complete problem generalizing probabilistic satisfiability (PSAT). A detailed technical framework (based on the notion of distributed security setting, and that unifies previously studied properties such as Distributed Noninterference, Distributed Non-disclosure and Flow Policy Confinement) was developed for addressing the problem of enforcing information flow security in client-side web applications. 4.3.3.3.3 Internet Security The group has worked on a world-wide distributed probing methodology to detect traffic routing variations. Upon detection, a corporate customer cannot act in terms of Internet-scale routing but can warn its network service providers and request consequent actions. This work was further complemented by the development of a formal model for Netfilter for specification and verification of firewall policies. Furthermore, an efficient and non-intrusive algorithm 158 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA for detecting performance anomalies in multi-tier virtualized services running in datacenters was developed. On different lines, two prototypes of mobile applications integrating cryptography primitives were developed, including a complete suite of services for securing communications and storage on mobile devices. Also, some work was performed on practical physical layer schemes for security. Research was also made on the application of artificial models of immune systems in computer network security. 4.3.3.3.4 Acess Control In relational database applications, access control is traditionally enforced by security layers based on centralized architectures. Work has been developed on security layers based on distributed architectures, which has also been extended to support NoSQL databases. The authentication problem was also addressed on smartphones, using User Behavior Modelling. 4.3.3.3.5 User Behavior Modeling Social networking services have emerged as an extremely popular platform for social interactions and created a new human communication paradigm. We developed a novel continuous time model based on a multi-ON-OFF Markov chain with exponential truncated sojourn times that is able to fully describe the sojourn times of different activity and non-activity periods, as well as the rate of interactions on a social network during the activity periods. This led to developments as a new means to authentication on smartphones based on previous user activity and on analyzing habits for construction of passwords of Portuguese people. 4.3.3.4 Interactive multimedia Given its very nature, Interactive multimedia addresses multiple areas, with direct social impact: − Health – Work was performed on a Health Kiosk (that automates the collection of vital signs and other medical data and is able to interact with the patients' health records) and on Voice Coaching for Reduced Stress (annotating utterances with stress using different methods (experts, heart rate sensors) and validation). − Games – Developments on algorithms for 3D virtual environments and MMOGs (massively multiplayer online games), including reconstruction algorithms, trust computing, and migration algorithms, and aspect of serious games technologies. − Human Interfaces – Two aspects were addressed: Augmented Reality with natural user Interfaces focusing on the natural interaction to allow users to manipulate data and digital systems; and 159 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA advanced remote control for user interaction with multimedia content. Look-a-Like avatars, for online cloud base engine, were developed, including aspects on Facial Synthesis within Virtual Reality. 4.3.3.5 Multimedia signal processing Many topics have been addressed by the multiple IT research groups in multimedia signal processing. The research topics are presented with a technical flow order logic, this means starting from analysis and going through coding, rendering and finally quality assessment. 4.3.3.5.1 Monoview video coding IT has addressed the: − Design of a novel HEVC based framework offering quality scalability on top of a HEVC compliant base layer while appropriately combining the predictive and distributed coding paradigms, a machine learning based side information creation mechanism and an adaptive correlation modelling process. − Design of two novel improved merge mode prediction solutions that adaptively refines the motion vector candidates in the context of the HEVC scalable extension to achieve the highest compression efficiency. − Design of a novel hybrid video coding solution combining pixel and feature based coding tools. − Assessment of the impact on distributed video coding (DVC) of upgrading the standard Intra coding component from H.264/AVC to the recent and more efficient HEVC standard to strengthen the DVC positioning in the video coding landscape. − Research and development of robust coding techniques to improve the error resilience of the state of the art video encoder (HEVC) based on dynamic reference picture selection modes. Added with specific enhancement techniques to mitigate the effect of partial or total loss of individual descriptions. − Fast intra coding procedures for HEVC. The intra coding operations defined in the HEVC standard require a significant amount of computation power during HEVC compatible video encoding. 4.3.3.5.2 Multiview video coding IT has handled the: − Design of a novel adaptive interactive multiview video streaming solution where clients select their preferred viewpoint in a given navigation window based on a layered multiview 160 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA representation. − Development of an inter-view SI creation technique for multiview distributed video coding using SIFT-based homographies relying on a local estimation process. 4.3.3.5.3 Light field image coding and processing IT has handled the: − Design of a non-scalable coding solution for light field image and video content, based on improved intra frame prediction methods that better exploit the inherent structure of this type of content. − Design of a scalable coding solution for light field image and video content, in which higher scalability layers correspond to richer interactivity possibilities for the consumer of the content. An investigation on depth extraction from light fields was initiated for the purpose of depth-based light field coding, among others such as surface analysis and modeling. − Development of interactive tools for rendering light field content, depth extraction and quality assessment. New degrees of freedom in terms of 3D light field content processing and coding have been also explored, such as the investigation of light field depth estimation techniques, light field depth image based rendering techniques, and geometric-transform based coding. These activities have been carried out under the scope of the ICT COST Action IC1105 - 3D-ConTourNet and IT project 3D-SERVICIS. 4.3.3.5.4 Holographic and Point cloud coding Design of a point cloud compression technique that involves partitioning of the point cloud data into clusters where each cluster can be independently spectral transformed to obtain coefficients for each vertex of a cluster. IT has also developed a more efficient HEVC based holographic data coding solution by including optimized transforms for each Intra coding mode; the optimized transforms improve the capability of the codec to consider directional redundancies. 4.3.3.5.5 Visual rendering In computer graphics, IT has developed algorithms for the simulation and rendering of weather clouds, as well as algorithms for ray casting and tracing, and for occlusion culling. It has also developed geometric algorithms to render molecules with millions of atoms. IT has developed an Epipolar Plane Image (EPI) based view rendering framework for 3D video coding representing the cube of views (3D light field) by a cube of EPIs whose compact representation involves 161 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA disparity estimation based on all the views available, rather than only a few, thus offering a global approach to synthesis. Also, IT has developed a light field based 360o panoramas creation algorithms exploiting the potential of light field cameras. 4.3.3.5.6 Video processing for streaming Design of a novel decoder quality boosting algorithm based on machine learning where any standard compliant bitstreams are decoded with better quality in the lower rate/quality periods that succeed to higher rate/quality periods due to network bandwidth variations. 4.3.3.5.7 Image and video coding/decoding It performed research on image and video compression techniques beyond the current coding standards: − Three-dimensional pattern matching algorithms and the application of geometric transforms in disparity compensation in 3D video coding. − Computationally efficient techniques for image compression in many-core platforms. − Summarisation and key-frame extraction algorithms for 2D/3D video. 4.3.3.5.8 3D Video Several initiatives on 3D covered: − 3D Video summarization When a user needs spend less time to view a video clip than its total runtime it usually resorts to fast-forward viewing mode. This strategy however is not necessarily the best one as it treats the entire movie as equally relevant. A better solution is to use a summarization pre-processing stage, to identify the more relevant frames of the video clip allowing a compliant player to reproduce only those frames marked as belonging to the summary. The special case of 3D video poses additional challenges related to the importance of depth information − 3D Video Quality of Experience Estimation 3D video represented in one of the several accepted formats (stereo, texture+depth, ,multi view) and transmitted in packet switched networks (after encoding) is subjected to significant degradations when packet losses occur. The goal of the research activities currently being carried out under this topic is the modeling and test of final QoE estimators that are able to predict the final quality of decoded video as perceived by human observers. A family of low-complexity models based on neural networks and making use of 162 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA packet-layer only information have been developed which present good performance. A new model for quality monitoring of 3D video (video-plus-depth format) delivered over hybrid broadcasting networks was devised. A new perceptually aware quality metric was also successfully developed and validated. − Development of error concealment methods specifically targeted for depth maps and efficient processing techniques for quality enhancing of depth maps generated by RGB-D Sensors. Novel error concealment methods based on geometric transforms were proposed to recover corrupted depth maps in 3D multiview video-plus-depth. − Crowd Evaluation of 3D Video Quality This line of research deals with the development of procedures and platforms that can be used to collect 3D video quality grades using a distributed crowd paradigm. 4.3.3.6 Pattern and image analysis IT has developed research on pattern and image analysis in different fields. 4.3.3.6.1 Image Quality assessment The area of quality assessment is an increasingly important area in image. IT has addressed the following techniques in quality assessment: − Eye gaze behavior under chromatic impairments and quality assessment: Attention maps of images with induced chromatic errors are obtained with an eye-tracking device. Those attention maps are analyzed and compared with the MOS obtained from the subjective evaluation of the considered images. − Specific Chromatic Errors Quality Assessment: Color change results from the application of a predefined chromatic error to the chromatic coordinates of all pixels were displayed for subject’s visualization that were asked to rank their quality based on their naturalness. − Quality comparison of the HEVC and VP9 encoders performance: A subjective test for assessment of the Quality of Experience provided by the two codecs was performed. − Benchmarking of objective quality metrics for HDR image quality assessment: In total, 35 objective metrics were benchmarked using subjective scores as ground truth. For each metric, objective scores were fitted to subjective scores using logistic fitting. − Evaluation of the emerging JPEG XT image compression standard: The question addressed here is to understand if this model allows extracting a new LDR representation using a different TMO, independently of the TMO used to generate the LDR image encoded in the base layer. 163 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA 4.3.3.6.2 Speech Processing The work on the field of robust acoustic modelling has been continued with children's speech models for reading assessment, as well as measurement of reading proficiency in children. Under the scope of LetsRead project, that aims to develop a Computer-Assisted Language Learning (CALL) mobile, interactive, application, for helping Portuguese children in their reading activity at the primary/elementary school level, a speech database from children (6-10 years old) on private and public schools was created. Full annotation was accomplished for words, disfluencies (cut/interrupted/wrong/extra words, filled pauses) and special events, in order to enable research and development on acoustic and pronunciation models. Furthermore, an automatic speech recognition module integrated in an automatic sign language interpreter was developed. 4.3.3.6.3 Transportation Systems IT has designed an analysis algorithm for road pavement surface images targeting the automatic detection and characterization of cracks. A toolbox (CrackIT) has been made available for researchers working on the problem of road infrastructures management.

Furthermore, IT developed a biometric recognition system for matching partial and degraded (by one of several degradation types) palmprints obtained from forensic scenarios against palmprints registered in a database. 4.3.3.6.6 Analysis and description of images and video Many aspects in image description were addressed: − Development of software tools, compliant with recommendation ITU-R BT.1702, for the real-time detection of video content with fast luminance variations, or with spatial patterns of high contrast (referred to as epileptogenic visual content). − Design of an algorithm for the detection of video segments without temporal activity and their classification as still images transmission, black frames, segments naturally without motion, and segments with repeated frames due to transmission losses or delays (video stalls). 165 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA − Design of an algorithm to identify video segments containing violence, using features extracted from the video and audio signals as well as from the subtitles text. − Design of a novel binary feature coding solution using distributed source coding principles where the features are extracted at the sensing nodes which are transmitted to enable visual analysis at some central location − Design of a novel multi-view distributed feature selection technique where the efficiency of the visual analysis is improved by employing several neighboring cameras which sense partially overlapped areas. − Design of a novel visual tracker that performs descriptor matching between consecutive frames, applies filtering techniques to remove undesirable outliers and employs a suitable model to characterize the object appearance; in addition, techniques to code and transmit these description streams are employed. − Design of binary descriptor coding methods and a novel tracking-by-detection framework to perform visual tracking in a stereo-based analyze-then-compress system where features extracted from different cameras are used to characterize the object appearance with a suitable model. 4.3.3.7 Architectures, protocols and services IT has addressed multiple areas inside the field of architectures, protocols and services. Mobile network aspects will be addressed in the following section. 4.3.3.7.1 Multimedia and QoS-Aware Networking In terms of multimedia-related networking, IT developed a global OTT architecture, with content prediction, distributed caching and information delivery. This Content distribution network in over-thetop networks includes a feature of Automated Recording and OTT Publicity, and a complete a complete analysis of catchup-TV pattern consumption. Furthermore, IT has developed dynamic and adaptive resource reservation mechanisms for large distributed embedded systems. In particular we developed a mechanism to scale the FTT-SE protocol (Flexible Time-Triggered Switched Ethernet) as a central piece in a resource management framework. An architecture based on HaRTES (FTT-enabled) switches was also explored (see hardware realizations). Moreover, we continued the work towards network management with hierarchical traffic scheduling to provide hierarchies of virtual channels with mutual temporal isolation. 166 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA In a different line, IT developed a reliable streaming multicast protocol (and demonstrator) that scales to large number of clients using feedback-based Network Coding with judicious scheduling of clients feedback. 4.3.3.7.2 Information-Centric Networking Research in the area of ICN is a strong commitment of IT, with particular focus in flexible coordination of the network infrastructure, in the light of future networks and existing telecom driven cellular networks. This effort resulted in active participation in the Information Centric Networking Research Group (ICNRG) of the IRTF, resulting in drafts and the authorship of RFC 7476. 4.3.3.7.3 Software Defined Networking Networks are embracing the flexibility provided by software agents, and exploring novel use cases and services, which are enabled by the standardization efforts related to the OpenFlow protocol. The IT has applied OpenFlow to the realization of advanced mobility management solutions. In particular, it has built upon its long experience with fast mobility for cellular and wireless scenarios, developing solutions for end-to-end mobility, and edge node mobility control based on the novel SDN concepts and through OpenFlow. IT has also developed a Open-Flow based network management approach, and mechanisms and algorithms for fault-management and reconfiguration of network and cloud resources through SDN. 4.3.3.7.4 Network Function Virtualization Telecom providers are exploring the opportunities presented by SDN, and with particular interest the possibility of increased flexibility and decreased cost by virtualizing some of the network equipment. IT has worked closely with research partners, and telecom providers in the development of actual solutions for the virtualization of several components. This has led to the recognition of IT as an Official OpenStack Supporting Company, with the addition of IT to the OpenStack webpage. 4.3.3.8 Mobile Networks Mobile networks are one of the most active and diverse area in telecommunications. IT naturally is strongly involved in this area. 4.3.3.8.1 Vehicular Networks The commitment to vehicular networks has been well established for long. In the last year, work was performed in: integration of mobility mechanism with multihoming for the connection of vehicles to several networks simultaneously, as well as predictive mechanisms for selecting best connections; development of local services for Road Side Units; security aspects for vehicular networks; opportunistic 167 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA routing for vehicular networking; storage strategies using Helix emulator; dissemination strategies; protocols for Vehicular Delay Tolerant Networks; and integration of sensors in board unites of the vehicular network. The 600 vehicle network in Porto has been constantly running performance experiments and integrating new mechanisms; some of these mechanisms were also tested in the experimental network in the harbor of Leixões. 4.3.3.8.2 Mobile Ad-hoc Networks Closely associated with Vehicular Networks, nevertheless there were several works on mobile ad-hoc networks which had a wider application. IT has been involved in delay tolerant communications for navy scenarios, and for aquatic drones. Routing protocols for DTN (Q-Prophet), exploring the different quality of links, and with improvements for measuring the link quality in an integrated way, were some of the areas developed. 4.3.3.8.3 Mobility in Telecommunications Networks Besides the vehicular networking, IT has developed work on high performance mobility, and continues to advance this area by contributing with novel mobility management solutions. These solutions are thoroughly tested and mature, being able to provide effective mobility management mechanisms in a generalized form for most IEEE 802 based networks, as well as some 3GPP aligned cellular networks. IT has developed distributed mobility mechanisms in flat networks, and optimized traffic allocation in different technologies and networks 4.3.3.8.4 IoT, M2M and Smart Cities The internet is including devices in its fabric, creating an Internet of Things, and then an Internet of Everything. This trend is being specially felt on the concept of Smart Cities. IT has contributed to advanced scenarios and technologies by working on the design of management platforms, incorporating concepts related to security and high availability, with the integration of novel use cases and management interfaces, through custom solutions and conceptual designs. Some specific initiatives are worth explicit mention − Future Cities project - Porto Living Lab. Multiple areas were covered in this project: Data collection campaigns (Scope (policemen), MoodSensor (city-wide hapiness), FEUP mobility), APIs, device efficiency, Android gateways, service composition and performance evaluation of M2M as IoT infrastructure in terms of throughput and latency. Furthermore IT developed a management and payment system for the user, driver and fllet of buses, and development of a dashboard system that visualizes the estimated time of the buses in specific locations, with real-time information. 168 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA − Urban Mobility – Two different aspects were addressed: i) the development of the 5th generation of shared use bicycle systems, accommodating the use of electric bicycles and the consequent enlargement of the range of users, as well as the development of management and supervision services. and ii) a system for automatic car park management, which detects automatically the occupation of parking places, checks user authorizations, sends notifications of abnormal events to supervisors, measures the utilization time, etc. − Environment and Agriculture – Activities covering modernization and innovation based on ICT in agri-food companies of central region of Portugal have been trialed, as well as intelligent control systems for variable volumetric water reservoirs. The objective was to develop a novel technological solution to control energy consumption in an efficient way to minimize impacts on the environment. 4.3.3.8.5 5G and Future Internet The internet is in a clear revolution as new usage models appear and the efforts around 5G take place. IT is following the developments related to future architectures and solutions by participating in important associations, think tanks and consortia. In particular, an IT researcher is member of the 5G-PPP steering board, the most important 5G related European association. Also, IT is member of the CONFIG (COntrol Networks in FIve G) consortium which aims to develop an effective architecture for future 5G networks. 4.3.3.8.6 Networks and Services for Mobile Teams Two major areas were addressed: − Communications for teams of collaborating mobile autonomous robots. We developed a method that allows obtaining position confidence levels based on the uncertainties of the pair-wise distances. We also explored routing within TDMA multi-hop networks and we developed a new protocol that strongly reduces the variations of end-to-end latencies and isolates the traffic flows generated by different sources providing network-wide composability in the time domain. − Vital Responder 2 project. Development of a prototype for ECG data collection over a wireless MANET of smartphones. Mobile MANET prototype on RPi. Experimental performance evaluation: energy consumption, communication range, network connectivity and throughput. Protocol for data collection on mobile ad-hoc networks using network coding. Network calculus framework for delay and backlog analysis of data gathering in a wireless MANET. 169 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA 4.3.3.9 Information Technologies Two major areas have been addressed in terms of Information Technologies: Big Data and Knowledge Development and Sharing. 4.3.3.9.1 Big Data Social Analysis The amounts of data currently available rapidly enables novel use cases for exploiting services and devices, considering that its volumes are able to be processed and it presents a clear structure. Work was performed in both areas related to the extraction of structure from unstructured (IoT) data, and the analysis of large data sets to provide clues enhancing existing services. This has led to several contributions as well as novel methods for real time processing of large amounts of unstructured textual information, knowledge extraction and the creation of clues for enhancing multimedia services. 4.3.3.9.2 Knowledge Development and Sharing Several artificial intelligence techniques were explored, and novel techniques were developed in these fields: agent architectures; Hierarchical Reinforcement Learning; Dynamic Scheduling; and Time Sequence clustering and prediction. Areas where these techniques were explored was on robot control in multi-robot systems, and on the treatment and tracking of Alzheimer’s disease. 4.3.3.10 Hardware Realizations The Networks and Multimedia line have developed several activities coupled with physical realizations of some concepts, due to the challenging realization requirements of such concepts. Two major lines have been tackled: parallel realizations and embedded devices. 4.3.3.10.1 Parallel Computing Significate amount of work was performed for the development of parallel kernels and data structures for accelerating compute-intensive signal processing algorithms under the context of error correcting codes used in data communications, in the area of medical imaging for diagnosis support, 3D reconstruction from stereo pairs and in the study of electron wave propagation on graphene. Mobile GPUs, low power FPGAs (reconfigurable hardware), GPU were tools used for multiple applications: Stacked Autoencoder Neural Networks; real-time 3D reconstruction; parallel kernels based on 2D stereo inputs; non-binary LDPC decoders, with mitigation techniques and analysis; medical imaging and signal processing acceleration (ultrasound, blood analysis, etc…). Both OpenCL and CUDA have been used in these developments. 170 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA 4.3.3.10.2 Embeded Systems Many networked embedded systems have real-time constraints and are safety critical. Thus it is require to handle implementation of standards-based dependable real-time communications for safety-critical systems, both wired (e.g. CAN and Ethernet) and wireless (e.g. IEEE 802.11, IEEE 802.15.4). Fault tolerance techniques for both wireless and wireline networks have been developed, exploring dynamic scheduling features of the VFTT protocol (in the wireline) and architectures for allowing coordination among overlapping base stations (in the wireless). This was enriched by developing HaRTES, a real-time Ethernet architecture that conciliates flexibility with real-time requirements, and with support with MAC Bridge standard functionalities, to make it capable of being integrated on Industrial Internet of Things frameworks. In order to support heterogeneous applications with demanding communication requirements and provide efficient application development processes, it was developed a framework integrating 6LoWPAN protocols and services on a real-time operating system (Contiki OS) for low-end microcontrollers. IT has also developed a prototype board that supports multiple sensors and Bluetooth LE to send biodata to a smart phone, including an onboard oximeter with red and infrared LEDs to boost the light intensity and improve the measurement accuracy under normal daily life conditions. The experimental nature of this oximeter, imposes the use of custom data profile for Bluetooth LE communication and requires a custom application for processing the data. 171 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA 4.3.4 Running and Concluded Projects Overview Funding Agency Number (confidential) 3 ADI 2 ADI/QREN 1 CAPES/CNPq 1 EC 2 EC/FP7 1 EDP 1 ESF/COST 2 EU/FP7 3 FCT 12 FCT/ CMU 2 FCT/CAPES 1 FCT/CMU 1 FCT/PTDC 9 FEDER/QREN 1 IT/LA 11 NATO 1 PT Inovação 2 QREN 3 IP Beja 1 Ubiprism 1 iUZ Technologies Lda. 1 Veniam 1 KKS - Agência Sueca para o conhecimento 1 Activity in Projects Acron / Ref VERE 257695 Title VERE: Virtual Embodiment and Re-Embodiment Funding EU/FP7 Descript. This project aims at dissolving the boundary between the human body and surrogate representations in immersive virtual reality and physical reality. Dissolving the boundary 172 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA means that people have the illusion that their surrogate representation is their own body, and act and have thoughts that correspond to this. The work in VERE may be thought of as applied presence research and applied cognitive neuroscience, and it would also significantly add to scientific knowledge in these areas . Imagine that you could transfer your self to an artificial body – a virtual body as represented in virtual reality or a physical robotic body. Recent advances in cognitive neuroscience show that internalising a body beyond ourselves (external, remote, alien) is possible, that our body representation is highly malleable and may be altered by appropriate changes to the normal stimulus contingencies that we are used to in every day life. The purpose of this research is to make such body transference possible with two different modes (virtual and physical). On top of this technical achievement, that would be underpinned through ongoing neuroscience research on body representation, would be a number of practical applications that will be constructed and investigated during the project. Acron / Ref 3DVQM IT/LA/P01131/2011 Title 3D Video Quality Monitor Funding IT/LA Descript. The project is focussed on research and development of 3D video perceptual quality monitoring in error prone networks, such as the near future 3DTV services over IP or DVB networks. The challenge is to establish a set of (Quality of Experience) QoE metrics and their relationship with objective measurements that affect the overall QoE. These metrics are computed from a combination of transport network layer information, quality features of 3D video signal and coding parameters embedded in compressed streams. The project seeks to investigate No-Reference (NR) methods such that blind 3D quality assessment can be carried out at any point of the delivery chain including the receiving terminal. Such an approach is rather more challenging than Full-Reference (FR) or even Reduced-Reference (RR) methods, where either the original signal or partial information about it is available. Acron / Ref MUVIS PTDC/EEA-TEL/119804/2010 Title MUlti-view distributed coding for VIsual Sensor networks Funding FCT/PTDC Descript. Distributed video coding (DVC) is a compression paradigm based on two key Information Theory results from the 70s: the Slepian-Wolf and the Wyner-Ziv theorems. Contrary to 173 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA the available predictive video codecs, DVC codecs exploit the source statistics at the decoder providing functional benefits such as: 1) flexible distribution of the computational complexity between encoder and decoder; 2) in-built robustness to channel losses; 3) exploitation of Inter-view data correlation at the decoder. These functional benefits are very important for visual sensor networks, a network of wireless low-power video camera nodes, used for a wide range of applications such as surveillance, monitoring of remote areas or tele-presence systems. Visual sensor networks are characterized by: 1) Inter-view correlation between camera nodes with overlapped views; 2) up-link communication between many encoders (one at each camera node) to a few decoders; 3) independent compression of each view, since collaboration between cameras is difficult to implement or rather inefficient. Due to these characteristics, it is not efficient (or possible) to compress each captured view at a central node with the typical predictive approach, e.g. using the recent multi-view video coding H.264/MVC (Multi-view Video Coding) standard, since it implies to exploit spatial, temporal and Inter-view correlations at a rather high complexity encoder. The distributed coding approach provides a significant architectural benefit since it does not require any Inter-camera communication to explore the Inter-view correlation while the predictive approach requires the availability of all views at some central encoding location, forcing communication between cameras. This project will advance state-ofthe-art by developing competitive multi-view DVC solutions for visual sensor networks, notably by proposing: 1. Side information (SI) creation and correlation noised modeling: To fully exploit the potential of the multi-view distributed video coding paradigm, high quality side information (an estimation of the source created at the decoder) must be created by (jointly) exploiting temporal and Inter-view correlations. In this case, solutions that combine temporal and Inter-view SI estimators by using preliminary decoded data as helper information will be proposed. In addition, correlation noise models capturing the statistical correlation between the side information (available at the decoder) and the source (available at the encoder) will also be proposed along with the estimation of the relevant parameters. 2. Hybrid predictive-distributed video coding: The combination of predictive coding techniques, to exploit the temporal correlation, with distributed coding techniques, to exploit the Inter-view correlation, may be a successful “cocktail” to obtain improved rate-distortion (RD) performance. This approach was never exploited before (as much as the authors know) and will require to reinvent popular coding techniques at both encoder and decoder. In this case, it is also expected to obtain error resilience improvements, which is quite important in this type of errorprone networks (typically wireless).

The objective of this project is developing a network framework, based on switched Ethernet, suitable to support CPS, by including an explicit and efficient support to component-oriented design methodologies. The framework shall support: Heterogeneous traffic classes with temporal isolation; - Partitioning and virtualization mechanisms; - Hierarchical multi-level server composition; - Dynamic adaptation and reconfiguration of servers with temporal guarantees; - Analytical tools for supporting the design of CPS; - Middleware for service management; Acron / Ref ROCOP2P TC-13_12 Title Robust Video Coding for Peer-to-Peer Media Streaming Funding FCT Descript. The main objectives of this project, are: - Study the use of MAP-decoding of MVs when applied to packet networks. Analysis of complexity constraints related with MAP decoding. Analysis of performance when compared to previous central decoding presented in [24], in the context of P2P transmissions. MAP decoding present excellent robustness but with some complexity, so we must study his feasibility and found the best trade of between robustness and complexity. - Specification of a bit allocation model based on multi-resolution analysis (wavelets) that effectively enables highly scalable video coding. In this case the bit-allocation should consider simultaneously temporal and spatial decomposition. - Optimization of the number of descriptions and bit allocation of video information based on contextual peer information such as number of available peers, rarity/abundance of a determined bitstream-chunk, etc.. - With these contributions we also aim to improve the video quality of state-of-the-art applications demanding video transmission using low-complexity. Acron / Ref COST IC 1106 COST IC 1106 Title Integrating Biometrics and Forensics for the Digital Age Funding ESF/COST Descript. “Forensics is the application of a broad spectrum of sciences to answer questions of interest to a legal system. This may be in relation to a crime or a civil action” [Wikipedia]. Since many such questions boil down to identifying, or verifying the identity, of people 175 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA allegedly involved in some action, a clear relationship exists between forensics and biometrics. Biometrics developed a number of techniques which can clearly facilitate the identification of people involved in criminal actions or civil incidents. Thus, although the two communities have traditionally often operated in relative isolation, there are many scenarios where the synergic cooperation of multimodal biometrics and forensics can be successfully applied. To address such multifaceted areas it is important to develop an interdisciplinary network with complementary competences, to foster the birth of a new community which can develop novel technological solutions to crucial issues and new challenges in forensic science. The Action will promote new partnerships, will provide education and training, will contribute to develop new standards and best practices, will produce awareness of the potential benefits of advanced technologies for evidence analysis in forensic cases and will stimulate improved mutual understanding of collaborative working models linking the academic and industrial sectors. Acron / Ref 3D-ConTourNet COST IC1105 Title 3D Content Creation, Coding and Transmission over Future Media Networks Funding EC/FP7 Descript. This COST Action undertakes coordinated research collaboration, at European level, in 3D multimedia creation, encoding, delivery and reception of services and applications over future networking technologies. A scientific framework is devised to integrate the main elements of the delivery chain, such as 3D content creation and encoding evolution, transmission across heterogeneous networks and user consumption, taking perceived quality as an overall key performance factor. Several individual R&D efforts are currently running across Europe, targeted at 3D technologies. This Action aims at beyond this trend by tightening closer together scattered efforts and integrating all technological elements with user 3D quality perception. To reach this goal, this Action fuels cooperation between researchers and industry experts, envisaging production of technical and scientific deliverables for researchers, scientists, engineers and managers, new business model recommendations for content and service providers through joint meetings across academia and industry, plus documentation and multimedia presentations to promote 3D technology in the society. The benefits include increased relevancy of European research, contribution to the development and sustainability of new and better 3D multimedia communications technology and provision of a platform for faster launching and adoption of related new products and services across Europe for end users’ beneficiary. 176 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA Acron / Ref VOCE PTDC/EEA-ELC/121018/2010 Title Voice Coach for Reduced Stress Funding FCT/PTDC Descript.

Specifically, the tasks shall produce the following deliverables: 1) a large database of spontaneous speech samples multiply tagged for being used in the development of automatic stress recognition methods; 2) speech feature extraction algorithms that are capable of real-time performance, as well as the tagging of the samples in the database.; 3) a reduced set of features relevant for stress classification, a classification algorithm that can classify stress levels in real-time, a benchmark evaluation of the various machine learning approaches to automatic stress classification, using similar evaluation methodology and sample data set; 4) an application that integrates the results of the previous tasks and evaluate its accuracy and response times, both in laboratory settings with elicited emotions and in real-life trials. Acron / Ref GreenEyes 296676 Title Networked energy-aware visual analysis Funding EU/FP7 Descript. The potential of the Internet of Things is leading to a paradigm shift with an ambitious long-term vision, in which battery-operated sensing nodes are empowered with sight and are capable of complex visual analysis tasks. Unfortunately, this is out of reach with the current technology. GreenEyes will develop a comprehensive set of new methodologies, algorithms and protocols, to empower wireless sensor networks with vision capabilities comparable to those achievable by power-eager smart camera systems. The key tenet is that most visual analysis tasks can be carried out based on a succinct representation of the image, which entails both global and local features, while it disregards the underlying pixel-level representation. Still, under severe energy constraints it is imperative to optimize the computation, the coding and the transmission of the features. On the computation and coding side, GreenEyes will tackle the problem by reversing the conventional compress-then-analyze paradigm. That is, image features are collected by sensing nodes, processed, and delivered to final destination(s) in order to enable higher level visual analysis tasks by means of either centralized or distributed 177 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA detectors and classifiers, somewhat mimicking the processing of visual stimuli in the early visual system. The transmission of visual features is subject to tight applicationdependent requirements (bandwidth/delay guarantees), and may be affected by network conditions. Therefore, on the communication side, GreenEyes will pursue the design of networking tools for wireless multimedia sensor networks for energy efficient distributed control, information delivery and in-network processing optimized for the visual analysis task.

Acron / Ref MODCOMP PTDC/EEI-TEL/2016/2012 Title Modeling User Behavior in Social Networks Funding FCT/PTDC Descript. Social networks have become an integral part of the digital life of nowadays society. Indeed, the preponderance of these networks has increased significantly in the last years, allowing users to share different types of multimedia contents with the community [FB, FK, YT, TW, LN, Ala08]. In the last years, we have also assisted to a dramatic increase on the number of attacks on these networks in order to obtain and access confidential data from several users. In this manner, it is possible to create and 178 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA execute powerful targeted social network attacks which, by exploiting the information shared on such networks, can become more credible and difficult to detect. Indeed, according to a recent report, the number of phishing attacks over social networks has increased more than 1200% during 2010 [Microsoft11]. The project Social Network User Behavior Modeling aims at analyzing and modeling the behaviors of social networks users in order to create behavior models. With such models, the project aims at increasing the knowledge the users have of their connections and of the social network in general, creating a trust relationship between the user and the remaining community. These models will also allow the detection of profile changes, or behavior models, in order to detect compromised accounts or accounts created by hackers with the purpose of accessing informations other users may share over the mentioned networks. The creation of such models enables the social network to map each user to group, allowing a more efficient, direct and secure management of existing groups of users as well as the creation of novel groups. Novel recommendation systems can also be proposed. All the mentioned aspects illustrate the importance of this project.

The main objective of the project ?Quality Control on the Go? (QC OTG) is the 179 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA development of a tool, integrated in the process of capture and ingest, which enables the analysis, in real time, of the quality of audio-visual content in three dimensions video, audio and file container - in an automatic way and compliant with acquisition systems based on files and SDI . This project is promoted by the consortium formed by MOG Technologies (leader), IST, ISCTE-IUL and IPN. The new product to be developed under the scope of this project is targeted at the audio-visual and broadcast sectors (especially producers of audio-visual content), presenting a set of innovative features, of which we highlight: analysis, detection of artifacts of audio and video contents in various formats (already available or near completion, as for example Sony XAVC) and with different targets (UHDTB, HDTV, Internet, Mobile); Fully integration of the features of capture and ingest with the system of quality control of the video, audio, and file container, ensuring the operation proceeds at real time; Integration of a library with a wide range of modular functions that enable extraction and analysis of information of video and audio (semantic and syntactic); Higher efficiency of the ingest process by introducing a single step of quality control therefore reducing the necessary computational resources. Aiming at fulfilling the goals and innovative characteristics that the project proposes, the consortium has established a methodology that comprises research and industrial development activities, counting with the involvement of a total of 26 human resources of the consortium and with a total investment of 1.192.093,72 Euros (including the acquisition of equipment and expenses with activities of promotion and dissemination of the results).

The main scientific goal of this project is to research algorithms applicable in long-term home monitoring contexts for the assessment of cardiac function, the key variable in cardiovascular disease (CVD) management, using a multi-channel heart sound 180 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA auscultation approach. Clinical applications will be developed for early detection of Heart Failure (HF) decompensation episodes in elderly and neonatal populations; both will be clinically assessed using in-hospital studies. Acron / Ref CATARATA PTDC/DTP-PIC/0419/2012 Title DEVELOPMENT OF NEW METHODOLOGIES BASED ON ULTRASOUND TECHNIQUES FOR IN VIVO CATARACT CHARACTERIZATION Funding FCT/PTDC Descript. Cataract is a clouding or opacity that develops in the crystalline lens of the eye. For clinical prognostic and therapeutic purposes it is very important to identify the cataract type and the disease stages especially in its early stages (Paunk 2007). With increasing relevancy, the ultrasounds appear as powerful, noninvasive and less expensive technique for tissue evaluation. Concerning to cataract treatment, phacoemulsification is the most common surgical procedure by using a hand-held ultrasonic device to fragment the clouded lens into small pieces that are then aspirated (Wilson 2005). To emulsify the cataract, the selection of the optimal ultrasound energy level is of fundamental importance to prevent the endothelial cells damage and the posterior capsule rupture. This unrecovered injury can be avoided if the hardness of the cataractous lens is previously and correctly estimated. The applicability of the ultrasound methods for characterizing both normal and cataractous lenses has been studied for decades. Two important ultrasound parameters, velocity and frequency- dependent attenuation have been used trying to evaluate the hardness of the cataractous lens in porcine and human eye tissue. The most important one is related to the fact the results only provide information about the cataract presence and respective hardness globally, because evaluation is made considering the anterior and posterior reflected lens signals. Thus, important information as the exact regional hardness of cataract is not achieved with this methodology. Also, there is no adequate noninvasive characterization of regional location and hardness of cataract. This is of particular importance for estimating the optimal phacoemulsification energy, which should be adjusted for the different hardness levels that can be found in all extension of cataract. In this project it is intended to use the backscattering signals, instead of the anterior and posterior lens echo signals frequently used in literature, to extract features capable to characterize the mechanical properties of tissues, namely scatter density and mean scatter size for subsequent correlation with the lens hardness. Time and frequency domain features will be evaluated in order to identify the most powerful ones. Several feature classifiers such as Artificial Neural Networks, Support Vector Machines, k-Nearest neighbors, and Naive Bayes will be tested and their potential evaluated for quantification of regional changing of cataract hardness. To develop a medical device for cataract surgery and clinicians 181 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA support to access cataract hardness and location for any type of cataract, and determine in real-time the optimal energy for phacoemulsification, pre-clinical studies will be performed in vitro, in porcine lens, and in vivo in rats animal models that simulate different types of cataract. The animal models will allow the translation from pre-clinical to clinical research.

Ambient Assisted Living (AAL) is an area of research based on Information and Communication Technologies (ICT), medical research, and sociological research. AAL is based on the notion that technology and science can provide improvements in the quality of life for people in their homes, and that it can reduce the financial burden on the budgets of European healthcare providers. The concept of Enhanced Living Environments (ELE) refers to the AAL area that is more related with the Information and Communication Technologies. To design, plan, deploy and operate, an AAL system often comprehends the integration of several scientific areas. The Architectures, Algorithms and Platforms for Enhanced Living Environments (AAPELE) COST Action addresses the issues of defining software, hardware and service architectures for AAL, on studying and creating more efficient algorithms for AAL, particularly those related to the processing of large amounts of data and of biosignals in lossy environments, and on the research of protocols for AAL or, with more detail, on studying communication and data transmission protocols for AAL. This Action aims to promote interdisciplinary research on AAL, through the creation of a research and development community of scientists and entrepreneurs, focusing on AAL algorithms, architectures and platforms, having in view the advance of science in this area and the development of new and innovative solutions.

This work aims to develop a technological module for Portuguese children, able to detect mispronunciations, hesitations and other disfluency indicators, in order to compute an overall reading ability index. The main problem consists in the detection of mispronunciations, which requires detailed acoustic models and new detection techniques dealing with speech variability using models of allowable pronunciations. The developed methods can be put to use in a prototype application, useful not only for the children, but also for the teachers and tutors that are involved in their education.

Acron / Ref GLANCES P01229 Title Generalized Linear Amplification with Nonlinear Components for Power and Spectral Efficient Broadband Wireless Systems Funding IT/LA Descript. Broadband wireless systems require high power and spectral efficiencies, and transmission over severely time-dispersive channels. Developing on the concept of Linear Amplification with Non- Linear Components (LINC), the main technical objective of the project is to design, implement and validate a new set of digital transmission techniques with high power and spectral efficiency for future wireless broadband systems to be employed in the uplink of mobile systems or in satellite communications. Our main goal is to design signals with low Peak-to-Average Power Ratio (PAPR) or even quasi-constant envelope and high spectral efficiency, employing amplification techniques based on low- cost, highly efficient grossly NonLinear (NL) amplifiers (e.g., class D and E amplifiers), which are simpler and have higher amplification and output 184 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA power then quasi-linear amplifiers. Since a grossly NL amplifier is only suitable for signals with quasi-constant envelope, we will develop new signal designs and/or transmission techniques compatible with grossly NL amplifiers. This research project combines theoretical development (including signal and receiver design), CMOS implementation of key components (with emphasis on matched amplifiers and output power combination with minimum losses) and FPGA-based implementation for an overall system’s proof of concept, for the most promising techniques. Acron / Ref HANCAD PEst-OE/EEI/LA0008/2013 Title Heterogeneous Ad-hoc Network for the Coordination of Aquatic Drones Funding IT/LA Descript. The goals of this project are to design, implement, and evaluate a heterogeneous network architecture for aquatic drones, and to demonstrate the feasibility of collectives of low-cost aquatic drones for maritime tasks such as environmental monitoring, sea life localization, and sea border patrolling. Common to such tasks is that they require collectives composed of large numbers of drones. The feasibility of a system for such tasks therefore depends on the unit cost (which should be kept as low as possible), and on the capacity of the network architecture and control logic to scale. As the number of units increases, unit failure will become more frequent and fault tolerance must therefore be built into both the network architecture and the control logic. The specific challenges to be addressed in the HANCAD project are: • Development of a scalable, heterogeneous, and fault-tolerant ad-hoc network architecture for aquatic drones • Synthesis of decentralized control logic to maintain network connectivity during task execution • Implementation and demonstration of a collective of 10 low-cost aquatic drones performing proof-of-concept tasks.

Acron / Ref S-DiaSelMan PEst-OE/EEI/LA0008/2013 Title Smart Diabetes Self-Management Care Funding FCT Descript. Diabetes is a rising disease in terms of number of people affected and the costs associated with its treatment. 439 million adults and USD490 billion are estimated by 2030. Portugal had, in 2011, 12.7% of the population between 20 and 79 with the disease. This project aims to develop a smartphone application to help the diabetic patient deal with managing the disease. A first step is to enable data recordings of the daily diabetic life in an intuitive and simple way, so not to be a burden, which can undermine the gathering of the information. This information taking should be seen more as a process (e.g.: having a meal implies registering carbohydrates, glycaemia, insulin) than a direct and separate register of several records. A second step is to incorporate the knowledge/protocols of doctors and nurses into the application. These protocols allow to react to certain patterns of behaviour, detected by the records taken. As an example, it could warn the user that it made exercise 2h ago and that perhaps her insulin dose should be adjusted, or that the current illness situation (that has been going on for 2 days) would merit an insulin correction. A third phase would be the pattern analysis of the data gathered, to search for patterns in two ways. One would be to provide feedback for the patient regarding some behaviour/actions that may be inducing erratic or bad disease control, e.g. detection of recurring low values before bedtime occurring when high values of carbohydrates where consumed at dinner time. The other perspective, would be for a more global analysis using the aggregated data from several patients for medical purposes. Here insights on insulin adjustments, differences between patients using same approaches, unknown correlations could be analysed from an endocrinologist point of view with more data to support it.

Whenever appropriate, the emerging scalable extensions of the High Efficiency Video Coding (SHVC) standard will be explored by extending these solutions to 3D holoscopic content.

Acron / Ref MEDICOMP Title Spatiotemporal compression of volumetric medical images Funding IT/LA Descript. In this project, we aim to develop new spatiotemporal prediction tools, as an alternative to the traditional frame-by-frame intra and inter prediction techniques. Since motion estimation is one of most computationally demanding tasks on hybrid video codecs, the alternative spatiotemporal techniques can give an important contribute while developing low complexity/high performance video codecs. Particularly, it was demonstrated that not only the Least-squares prediction can achieve competitive results when compared to the traditional motion estimation, but also that there exists a strong correlation between edges in space and object trajectories in the time domain. Based on these observations, we believe that both the spatial and temporal redundancy can be exploited with similar approaches, namely using three- dimensional coding units. 187 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA Acron / Ref OPAC P01270 Title Optimization of pattern-matching compression algorithms for GPU’s Funding IT/LA Descript.

Two main general objectives will be pursued in this research project: - Studying the perceptual influence of several factors on QoE, - Definition of a QoE evaluation model for video applications. For that we will propose solutions for the following challenges: - To study the influence in the QoE of the different factors related with video and streaming. o Subjective test, and hence MOS values and other statistic properties will be used to evaluate the video quality when subjected to different impairments. o Using the detection of points of interest to study the local influence of perturbation on QoE assessment. - With the MOS assessment and the visual attention results, different factors that have influence in the QoE evaluation will be identified. - The influence of the different factors will be quantified using appropriate features in a multidimensional space. Appropriate decision methods, based on representative examples will be used to evaluate QoE. - To study and develop QoE models for QoE evaluation of video applications that can present a better correlation than the existing in the literature (which in the current state do not present acceptable correlation to be used in real scenarios). In this context, this project aims to provide a valuable research for QoE modelling on Video applications. Acron / Ref PAConvex PTDC/EEI-PRO/1470/2012 Title Beyond Convexity: Non-Convex Optimization and Game-Theoretic Approaches for Imaging Inverse Problems 188 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA Funding FCT Descript. Imaging inverse problems (IIPs) abound in the modern world. Medical imaging (CT, MRI, PET, ultrasound), remote sensing, seismography, non-destructive inspection, digital photography, astronomy, all involve at their computational core the solution of IIPs: they produce visual representations (images) of an underlying reality from indirect/imperfect observations. In a nutshell, the goal of this project is to advance the state of the art in computational methods for IIPs, by exploiting the promising new possibilities that lie outside of the classical convex optimization approaches. IIPs are ill-posed: even if the observation operator is perfectly known, the observations do not uniquely and stably determine the solution. This difficulty is dealt with by seeking a compromise between data fidelity (fitting the observed data) and adherence to properties that the unknown image is known/desired to have. The classical way to seek this balance is to formulate an optimization problem (usually convex, more by reasons of mathematical tractability than model adequacy), where the objective function includes a term encouraging data fidelity and another (the regularizer/prior) penalizing undesirable solutions; in this approach, convex optimization takes center stage and has been in the limelight of computational imaging. If the observation operator is only partially known (in the so-called blind problems), the goal is to infer, not only the underlying image, but also the missing information about the observation model. Blind problems are obviously more ill-posed, requiring regularizers/priors that better model the images of interest. Moreover, variational formulations of blind IIPs are naturally non-convex, thus out of reach for the efficient convex optimization tools developed in the past decade for the convex formulations of non-blind IIPs. Consequently, the methods that have been proposed for blind problems lack convergence guarantees and require "tricks" in order to work well (e.g., careful initialization and continuation procedures), making it hard to trace their (non)success to the behavior of the optimization algorithm or the (in)adequacy of the objective function. Non-convexity also stems from using non-convex regularizers, even in non-blind IIPs, e.g., constraints/penalties on the number of coefficients that represent the image on some frame or dictionary. These non-convex regularizers are central in the recent theory of compressive sensing and much research has been devoted to finding conditions under which similar solutions are obtained with convex relaxations. Very recently, algorithms that directly tackle the non-convex formulations have been proposed by exploiting particular properties of the observation operator, namely their restricted isometry properties (RIP). However, in IIPs, the RIP is essentially impossible to guarantee, making the application of these non-convex approaches an open research front. This project aims at advancing the state of the art in computational methods for IIPs, by departing from the convex optimization realm and its limitations, in several directions: a) We will investigate optimization methods for non-convex formulations of blind IIPs; unlike previous approaches, we seek methods with theoretical guarantees and without careful user interaction. Of course, non-convex optimization can only be approached by exploiting specific characteristics of the class of problem in hand; this is 189 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA precisely the strategy we will follow. In particular, a recently proposed new class of algorithms for non-convex structured functions, based on the Kurdyka-Lojasiewicz property, is a promising tool for this quest. b) We will develop algorithms for nonconvex regularization, by exploiting the lines of attack that have recently been successfully followed for compressed sensing (CS). However, unlike in CS, the observation operators in general IIPs do not exhibit RIP, thus other characterizations are needed to support the sought for theoretical guarantees. c) For blind IIPs, we will seek formulations of the compromise between data fitness and regularization as equilibrium (rather than optimization) problems, namely via variational inequalities (VIs) and game theory. Since optimization problems are particular cases of VIs but the reciprocal is not true, this approach contains and extends the standard optimization formulation, opening the door to more general criteria and computational methods. For example, blind deblurring can be formulated as an equilibrium problem (a game) between estimating the underlying image and estimating the blur.

Acron / Ref SBikee ADI/38937 Title Smart Bikeemotion Funding ADI Descript. Bike sharing systems have been very successful in many cities worldwide. In Aveiro, Portugal, the BUGA system was pioneer, but it has never evolved to an automated operation mode. The first automated bike sharing system in Portugal, was deployed in Vilamoura in 2011/12. There are some relevant examples of popular and effective bike sharing system in Europe, notably in London, Paris, Barcelona, Madrid and Hamburg. Current automated bike sharing systems require docking stations to park the bicycles, to interface with the user and to connect them to the backhauling information system. The 193 ANNUAL REPORT 2015 – NETWORKS AND MULTIMEDIA evolution of these systems was mostly concentrated on the information systems, improving the usability, the access (mobile phone and web) and the payment process. We are witnessing a growing dissemination of electric bicycles. These bicycles behave like conventional bicycles, as they can be used without electrical motor support, or as semi-assisted electrical bikes (“pedelecs”), since the driver has to move the pedals. With electrical motor support, the autonomy is around 100km without significant driver physical effort, except the need to move the pedals. It is expected that this technology will multiply by 5 (from 6% today to 30%) the number of potential users of bike shared systems, encompassing people moving for work, people aged over 60 and people with poor physical shape unable to ride a standard bicycle for medium size journeys. The recently concluded bikeemotion® project, integrating Ponto.C, Ubiwhere, Micro I/O and the University of Aveiro, has developed a prototype fourth generation (station less) bike sharing system adaptable to any bicycle, in which the bicycle includes not only the locking system, but also GPS and mobile communications.

O objetivo principal do projeto NET-PORT será a conceção e desenvolvimento de novas soluções e serviços de rede, de elevado valor acrescentado, na área de sistemas de comunicação entre veículos para transportes e logística inteligente dentro de portos e aeroportos. Estas soluções e serviços vão ser suportados por uma infra-estrutura de rede sem fios de baixo custo de instalação e manutenção, assente em comunicações veículoa-veículo e veículo-a-infraestrutura que utilizam a norma IEEE 802.11p. Através da integração fiável e segura dos sistemas desenvolvidos com as redes internas e os sistemas de informação das autoridades que controlam e empresas que exploram portos e aeroportos, assim como com plataformas do tipo Cloud, o projeto NET-PORT permitirá à empresa VENIAM diferenciar a sua oferta para sistemas de controlo e gestão inteligentes em portos e aeroportos, oferecendo soluções chave na mão que introduzam melhorias significativas na segurança, eficiência, produtividade e impacto ambiental das operações de controlo e gestão em portos e aeroportos, potenciando assim o aumento da competitividade da empresa VENIAM, numa ótica de forte internacionalização. Como principais benefícios para as autoridades que controlam e empresas que exploram portos e aeroportos, o projeto NET-PORT vai desenvolver uma infra-estrutura de rede veicular de baixo custo, que possibilitará o aumento da qualidade e a redução dos custos de transmissão dos fluxos de informação e acesso à Internet por parte de todos os intervenientes nas operações a efetuar em portos e aeroportos. Além disso, a infraestrutura de rede desenvolvida vai potenciar a aquisição, em tempo real, de uma grande quantidade de informação de dados sobre as operações e movimentações de veículos, pessoas e mercadorias nestes meios. O objectivo deste trabalho é permitir a ligação simultânea a várias tecnologias e redes, para permitir a ligação de um veículo a vários veículos ou a várias estações em simultâneo, podendo distribuir vários serviços por várias ligações. Este trabalho permitirá distribuir o tráfego de veículos (por exemplo, autocarros) por várias ligações simultâneas, para melhorar a transferência de informação.

The detailed activities included: 4.4.3.1 Contributing groups • Applied Electromagnetics, Lx • Applied Mathematics, Co • Applied Mathematics, Cv • Security and Quantum Information, Lx • Instrumentation and Measurements, Lx • Integrated Circuits, Av • Integrated Circuits, Lx • Organic Electronics, Lx • Physics of Information, Lx • Power Electronics, Lx • Power Systems, Co • Power Systems, Cv 4.4.3.2 Scope and Objectives Basic Sciences and Enabling Technologies (BS&ET) is a multidisciplinary research line providing transversal background support to IT activities and mission. Most of the work in this line was related to electronics and optoelectronics. This applies to the activities in Applied Electromagnetics (AE), Integrated Circuits (IC), Power Systems (PS), Organic Electronics (OE), Power Electronics (PE) and 265 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES Instrumentation and Measurements (IM). The activities in Applied Mathematics (AM) supported research performed in other areas, developing tools relevant to telecommunications, and applications to Simulation, Mathematical Modelling and Systems Stability. Physics of Information was focused on quantum information theory, quantum effects in biological systems and energy transport, and nanoenergetics and quantum effects. 4.4.3.3 Expertise and Research Topics 4.4.3.3.1 Applied Electromagnetics The activities carried out by the group Applied Electromagnetics in 2015 were focused in the broad domain of Electromagnetic Field Theory and its applications to electric, magnetic, and optical devices, encompassing three major subareas: Transmission-line structures; Electric and magnetic field problems; and Computational electromagnetics. • Transmission-line structures - Hybrid multiwire transmission lines (HMTL) are novel transmission structures where magnetic transmission lines and standard electric transmission lines coexist and interact. The general matrix theory of HMTL was developed and later applied to a particular four-wire system, from where the coupling properties and the wave propagation features of the multiwire structure were obtained. - Overhead power lines were characterized, modelled, and their behavior simulated taking into account proximity and skin effects, longitudinal variations of the earth surface profile, and transverse earth stratification. - The propagation parameters of medium frequency transmission-line communication systems in circular cylindrical mine tunnels were evaluated using an exact method based on radial and azimuthal expansions of the magnetic vector potential. Results were compared with those obtained using Dubanton’s and Wait’s approximations. • Electric and magnetic field problems - Shielding techniques for magnetic field mitigation in power transmission lines were proposed and analyzed. - Magnetic field (3D) in the air gap of a ferromagnetic core with superconducting blocks, and 266 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES magnetic field in a spherical electrical machine, were modelled and analyzed. • Computational electromagnetics The development of computational methods and software tools for electromagnetic field calculation is key for most of the reported research activities, namely, the development of hybrid methods using both analytical and numerical formulations (finite element, and boundary element methods). During 2015, the topic of electromagnetic propagation in bent and ring slab waveguides, and the topic of magnetic field evaluation in air gaps of ferromagnetic cores, and in spherical electrical machines, received special attention. 4.4.3.3.2 Applied Mathematics The research on Applied Mathematics has been focused on Optimization and Numerical Linear Algebra, Logic and Computation and Criptography and quantum information. • Optimization and Numerical Linear Algebra - Numerical Linear Algebra: Preconditioning and convergence of iterative methods for the solution of linear systems of equations, generalized inverses and its applications. - Complementarity Problems: design, convergence analyses, implementation and testing of interior-point algorithms, active-set methods, sequential quadratic algorithms and enumerative methods. - Global Optimization: complementarity algorithms, positive semi-definite and reformulationlinearization techniques for bilevel programming, quadratic and bilinear programming, eigenvalue complementarity problems and mathematical programs with complementarity constraints. - Solution of structured optimization models arising in telecommunications, civil engineering, and finance. - Optical core networks - efficient ILP models and heuristic solutions for (i) the network design problem with fixed-grid and flexible grid setups and (ii) for the impairment aware routing problem. - Lightpath admission control algorithms for optical networks based on integer linear programming methods and performance evaluation based on simulations. - Hybrid approaches based on column generation and local search heuristics, for energy efficient 267 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES routing in telecommunications networks. - Routing algorithms for 6LoWPAN mesh networks. - ILP efficient models for (i) wireless mesh network design with node degree constraints, (ii) the single PON network design with unconstrained splitting stages and (iii) the optimal layout of wind farms for electrical power generation. • Logic and Computation - Combination of logics: substantial advances in the understanding of fibred logics was achieved, obtaining full characterizations of conservativity and decidability preservation results in the disjoint case, and several partial results in the general case, namely using appropriate notions of translation - Compositional meaning in logic: we have explored suitable generalized notions of compositional meaning in logic, namely in the context of non-deterministic logical matrices, and obtained several new characterization - Computation with real numbers and complexity: we have shown that the physical measure associated to the (geometric) Lorenz attractor is computable. We have shown how computational complexity can be properly defined over analog models of computation like Shannon's General Purpose Analog Computer (GPAC. We have shown that a function is polynomial-time computable with a GPAC if and only if it can be computed in polynomial-time with Turing-based computation models. • Criptography and quantum information - Bit-string oblivious transfer: we developed a quantum computationally secure protocol for bitstring oblivious transfer between two parties, under the assumption of quantum hardness of state distinguishability and the constraint of performing at most few-qubit measurements (leaving open the question of general attacks performed on all qubits involved). Our protocol is feasible, in the sense that it is implementable in polynomial time. - Blind signatures and PK: we propose a quantum blind signature which is perfectly secure under the assumption of a honest offline repository of quantum information. We also proposed a quantum public key cryptosystem. Quantum multiparty dense coding: we proposed a quantum multiparty dense coding protocol that allows the sharing of information among several quantum agents. 268 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES 4.4.3.3.3 Instrumentation and Measurement The Instrumentation and Measurement Group works in the broad domain of Metrology. In 2015, the activity of the Group can be included in the following main topics: - Non-destructive testing; - Sensors and transducers; - Signal acquisition and automated and telemetric measuring systems; - Signal processing applied to sensors and instrumentation. • Non-destructive testing - During the past year inspection has been carried out using the linear motion system acquired in 2013 for the Instrumentation and Measurement Laboratory. The non-destructive method used is based on motion induced eddy currents. Tests were performed to conclude about the defect depth in a conductive plate and the sensitivity of the method with velocity in aluminium materials. Studies are being made to apply the method to steel rails. - The cooperation initiated last year with Universidade Federal do Rio de Janeiro will continue. The objective is the development of a NDT testing system to detect cracks and modifications on the paramagnetic properties of the wall tubes of reformer furnaces. Some samples of deteriorated tubes have been received at the laboratory. Two remote field eddy current probes were built to compare detection and characterization capabilities in standard defects like longitudinal and transverse defects. Tests initialize now. - Work on the inversion problem algorithm applied in eddy current inspection using a sinusoidal magnetic field with fixed-amplitude is going on. A new probe with two coils able to produce orthogonal uniform magnetic fields in two wide areas in the sample to be inspected was built. Two tiny giant magnetoresistance sensors (GMR) with high sensitivity are used to measure the amplitude and phase of the magnetic field in the sample’s surface. A perturbation occurs in the measured magnetic field in the proximity of a crack defect. The current density is then determined around crack defect through an inversion problem algorithm. - A new non-destructive testing (NDT) method called transient eddy current oscillations (TECO) was developed and implemented to detect a change in the thickness of stainless steel covered with insulation. This method uses a probe built at the laboratory which consists of a capacitor 269 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES and an induction coil (excitation coil) discharging in a free oscillation mode, while the resultant magnetic field is detected by using a Hall-effect sensor. Different features were extracted from the response voltage to detect the thickness of the test specimen and separation of lift-off. - The use of algorithms in the area of digital signal processing to process and interpret data provided by the sensors used in the laboratory for eddy current testing proved to be very effective to overcome the poor performance of these sensors and to surpass the limitations of the traditional NDT methods. • Sensors and transducers - Design of a ew dual driver planar eddy current probe with dynamically controlled induction pattern. - Comparison of spin valve and magnetic tunnel junction magneto resistive sensors in eddy current testing probes. - Study and development of innovative solutions to perform accurate measurement of industrial variables (force, distance and flow). - Static and dynamic characterization of sensors and measurement system (polarography, heavy metals detectors, turbidity, pH and conductivity sensors). • Signal acquisition and automated and telemetric measuring systems - Heterodyning based portable instrument for eddy currents non-destructive testing. - Detection of micrometric surface defects in titanium using magnetic tunnel junction sensors. - Development, implementation and characterization of a DSP based data acquisition system with on-board processing. - Development, implementation, and characterization of a stand-alone embedded viscosity measurement system based on the impedance spectroscopy of a vibrating wire sensor. - Implementation and development of I&M industrial transmission systems based on Foundation Fieldbus (FF), HART e CAN protocols. - Development and implementation of a data acquisition system for teaching purposes. - In the domain of biomedical applications worth mentioning: - EMIT/EMBI Imaging (new prototype). 270 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES - Source localization (4D mapping of myocardial activity). - Magnetophoresis (new particle development and ferritin characterisation). - New contactless electrodes developed - Created device for the pneumocardial characterisation. - Design and implementation of different kinds of smart walkers including sensors for force, and acceleration and Bluetooth communication. - Hardware and mobile software for Electronic Health Record prototypes were developed and presented during a RSE Workshop as part of Portuguese Conference of Physiotherapists as part of PTDC/DTP-DES/1661/2012 activities. - Implementation of smart rollator prototype including motion pattern sensors expressed by microwave Doppler radar. - Development of mobile application for subjective and objective evaluation of physiotherapy sessions. • - Wearable solutions for cardiac and motor activity assessment. - Development of an emotion monitoring system.

Furthermore, we have shown how quantum short-range channels can be made more robust to noise by performing regular measurements on them, a counter-intuitive result yielding very good fidelities for quantum bit transfer across spin chain channels. • Furthermore, we have found that continuous-time quantum walks on random networks yield optimal quantum speed-up for spatial search. This was a very surprising and high impact result, as this optimality was only believed to hold for very regular and symmetric networks. Moreover, we were able to extend our result to show that it is possible to send a quantum bit of 277 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES information, with fidelity one, between two nodes that are not directly connected to each other, as well as establish maximal quantum correlations between such nodes. Overall, our results show that quantum information tasks can be very robust to spatial disorder, and open the way to explore optimal quantum information transmission and processing in random networks • Finally, we also investigated quantum information theory in the relativistic regime, and found that the degradation of quantum correlations between entangled parties subject to acceleration varies for different initial states that all have the same amount of entanglement, revealing that it is not only the initial amount of quantum correlations that is determinant for this loss of information. We have also started investigating the capacity of black holes to process and leak quantum information. • On the quantum effects in biological systems and energy transport front, namely in the context of EU FP7 project PAPETS, IT is applying the semi-classical method to simulate the vibrational dynamics of complex biomolecular networks, that it recently developed, to chromophoric systems, both natural and artificial. Furthermore, we have found that it is possible to have disorder-assisted quantum transport in sub-optimal decoherence regimes, contributing to further enlight the understanding of environment-assisted quantum dynamics. • On the nanoenergetics and quantum thermodynamics front, we have obtained a method to determine the minimal heat dissipation of quantum information erasure, and have successfully concluded the EU FP7 project LANDAUER (obtaining “Excellent” in the corresponding final review). Furthermore, we have started theoretical work on quantum refrigerators and on quantum heats engines, including some based on vacuum forces, whose potential experimental implementations we will also to investigate, namely in solid state systems based on graphene or Nitrogen-vacancy centres in diamond. Finally, we have started to investigate the role of nonMarkovianity in the dissipation related to irreversible information processing at the quantum level. • Finally, IT continued to play a key role in the coordination and consolidation of the FCT Doctoral Programme in the Physics and Mathematics of Information (DP-PMI) during the DP-PMI’s second year, as well as in the organization of its advanced courses in Quantum Information Technologies. Furthermore, IT continued to organize the Quantum Computation and Information Seminar and the Physics of Information Seminar, as well as the special colloquium delivered by Serge Haroche (Nobel Prize in Physics, 2012) in April 2015. 278 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES 4.4.3.3.7 Power electronics • Switching Audio Amplifiers - Continuing the study and development of power supply/amplifier integration and single stage switching audio power amplifiers.

Study of new MOS switching methods (including multithreshold switching) to reduce the impact of the introduction of switching DC-DC converters in System On a Chip - SoC. 4.4.3.3.8 Power Systems • Applied Electromagnetics - Computational electromagnetics - An electromagnetic analysis of a Variable Inductor (VI) of double E-shaped was developed. In the studied VI topology, a DC current was used to control the inductance of the VI through a series of electromagnetic phenomena. Therefore, to conduct the 279 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES electromagnetic analysis, a Finite Element Analysis (FEA) software was used. Some 3D VI models were built with the software. The obtained FEA results were analysed and compared with different models and experimental results. • Power electronics and systems - Resonant contactless energy transfer - IPT systems for electric vehicle charging – Control strategies were implemented for unidirectional IPT systems and resonant topologies with compensation were used. Simulation and experimental results were obtained. The efficiency and the power transference capability obtained by simulation were experimentally validated trough a developed prototype. A controller placed on the primary side of an IPT system based on a variable inductor was studied and simulated. This controller allows charging EV batteries with a constant current. A half-bridge topology for on-board IPT chargers was also researched. - Converters - DC-DC converters topologies for EV applications - A variable inductor has been implemented, which reduces the core size and improves the ripple content of the inductor current by controlling the core saturation in a reduced-scale 1 kW bidirectional converter prototype. Other developed research was the control and magnetic core optimization of an isolated DC-DC converter. From this work a prototype was built. - Multilevel converters for green energy - It was prepared a test bench with a doubly-fed induction generator, supplied by NPC converters. This setup is being used to develop research activities on condition monitoring of wind generators and, so far, results regarding rotor faults were obtained. - Multilevel converters faults - The fault detection capability during power converter operation has become an issue of paramount importance. Without a suitable diagnostic method, a semiconductor open circuit can remain undetectable for a long period of time, causing damage to the converter and for the system where it is installed. Following this issue, a study regarding the impact of open circuit faults in IGBTs of rectifiers and inverters that use a five levels NPC topology was investigated. A 280 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES simulation model for these type of converters was implemented in Matlab/Simulink®) and validated experimentally with a prototype developed for this purpose. - Uninterruptible power supply of double conversion - Over the last year several tasks regarding the implementation of the control and diagnostic strategies in an FPGA were developed. In order to get a predictive control technique with good performance and faster failure detection in the UPS, the main goal of the developed programing tasks on the FPGA has been the reduction of the sample time, taking into account their hardware resources. At this time the goal is almost achieved and ready to be tested. - Development of new control algorithms and strategies for Hybrid Solar PV-WindBattery solutions for power systems. - Simulation Models of hybrid Electric Traction Systems/Fast Charging Stations Network. - Motors - Predictive control – Predictive control algorithms for induction and synchronous reluctance motors were developed and tested in simulation environment.

A 2D finite element model was developed and several experimental tests were performed. During experimental tests, a previously designed data acquisition system was used to simultaneously measure thermal, electrical and mechanical data. - Optimization methods to design linear tubular switched reluctance generators. - Development of Drivers for Linear Switched Reluctance Actuators (LSRA) and new control approaches. - Analysis and characterization of the noise profiles of linear actuators in different conditions, operating regimes and also for different control algorithms. • Energy Harvest - Development of systems for generating energy from sea waves, by the adoption of linear absorption point device based on the principle of variable switched reluctance, keeping in 281 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES mind its adaptability to other energy harvesting systems. - Microbial Fuel Cells Optimization for use in water monitoring systems - The efficient use of water systems requires the availability of monitoring systems to collect the necessary information to improve system management.

Optimização das Técnicas de Desenho dos Instrumentos de Medida: Aquisição, Registo e Tratamento de Dados 282 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES Funding CRUP Descript. No projecto dos novos sensores submarinos profundos (OBS) é necessário ter em conta os resultados das experiências realizadas com os dispositivos actualmente existentes as quais demonstram que, de forma a conseguir-se uma maior versatilidade é imprescindível dedicar mais atenção a uma série de aspectos que afectam a electrónica e projecto de componentes, nomeadamente, a optimização da relação sinal/ruído. É necessário identificar as diferentes fontes de ruído e caracterizá-las distinguindo os sons hidrodinâmicos dos biológicos, industriais, sísmicos e térmicos. É necessário caracterizar e minimizar o ruído eléctrico gerado pelo sistema de aquisição e pelo condicionamento de sinal através de um processamento adequado. A interpretação dos perfis sísmicos envolve o reconhecimento de certos padrões geológicos como falhas, zonas altamente reflectivas, etc. que permitem identificar grandes zonas de textura comum, frequentemente associadas com processos geológicos relacionados. Os algoritmos de processamento, que utilizam técnicas tradicionais como a FFT, STFT, ondulas e filtragem digital, requerem a experiência de um geólogo para a interpretação correcta dos dados e para a extracção da informação desejada. Este processamento pode ser simplificado e automatizado no caso de uma boa relação sinal/ruído, especialmente importante no caso das ondas refractadas que apresentam um baixo nível de sinal em relação à onda directa incidente. Do ponto de vista do processamento de sinal, os sinais de tipo geofísico colocam problemas interessantes e têm sido bastante estudados, em particular aqueles que aparecem na sismografia tanto activa como passiva. A razão fundamental é que se tratam de sinais que não representam directamente as fontes que os geram (ruído, interferência, dispersão de propagação) que não são unidimensionais e para os quais o estímulo apresenta grandes limitações quanto ao tipo de sinais que se podem utilizar com esse fim. Não é de estranhar portanto que a maioria das técnicas de processamento tenha sido aplicada num sentido ou noutro sobre os sinais de origem geofísica: deconvolução cega, separação cega, reconhecimento com redes neuronais, ondulas para eliminação de ruído, etc. O principal objectivo do projecto centrar-se-à na validação dos resultados obtidos empregando sismómetros profundos, focando a actividade na caracterização e optimização do sistema de aquisição de dados. Estudando e propondo novos sistemas de integração da informação em redes de sensores distribuídos. Serão analisados e implementados os sistemas de interconexão baseados em Ethernet e em barramentos Can com aplicação das normas IEEE1451.

The scientific objective of this project is to test the fundamental limits in energy dissipation during the operation of physical switches representing the basic elements of logic gates. We address the physical limits arising from a generic switch mechanism that is common to any digital device, with specific reference to the fundamental limit arising from the decrease of information in the computation procedure, also known as Landauer limit.

Acron / Ref MAXBE 314408 Title Interoperable Monitoring, Diagnosis And Maintenance Strategies For Axle Bearings Funding EC/FP7 Descript. The axle bearing damage process has safety and economic implications on the exploitation of railways systems, as proved by the selection of this topic for inclusion in the present call for research proposals of the FP7 of the EU. Axle bearing damage has been the object of intense attention by railway operators and transportation authorities, leading to a variety of approaches and systems currently in place to deal with the problem. However in Europe there is some lack of standardisation which justifies R&D work on condition monitoring and early diagnosis of axle bearings by technology integration. Moreover the current European documents do not present any guidelines for the maintenance management of the rolling stocks with regards to axle bearings, which make the association of monitoring, diagnosis and maintenance an interesting approach. The MAXBE project appears in this context and its strategic objective is to provide validated and demonstrated concepts, strategies and guidelines for the interoperable axle bearing monitoring and diagnosis that support the railway operators and managers dealing with the threats imposed by the existence of axle bearing defects. The consortium for the MAXBE project comprises 17 partners (industry, leading universities, end-users and a SME) from 8 member states, representing operators, axle bearing manufactures, key players in the railway community and experts in the field of monitoring, maintenance and rolling stock. The presence in the consortium of one axle bearing manufacturer, market leader in the field, and three operators and railway managers, as end-users, is decisive for the enhancement and optimisation of the axle bearing diagnosis and maintenance strategies and for the definition of the new proposed approaches for the interoperability. The MAXBE project will have impact for the reliability, availability, maintainability and safety (RAMS) of rolling stock and infrastructure, focused on the axle bearings. 285 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES Acron / Ref INSPECT PTDC/EEI-PRO/3219/2012 (P.1206) Title INSPECT - Integrated Nano Sensor Probes and Electronics for Eddy Currents Testing Funding FCT/PTDC Descript. This research proposal aims to develop a state of the art Non-Destructive Testing (NDT) system to overcome current testing limitations on some specific industrial applications. The system will include a new eddy currents probe, combining coils, a Magnetoresistive (MR) sensors array and Complementary Metal-Oxide Semiconductor (CMOS) microelectronic circuits, which will work together with an eddy current generation element. Since the probe aims to be efficient for both superficial (requiring high frequency operation) and buried defects (requiring low frequency operation), coils have the disadvantage of having a frequency dependent sensitivity, which is lower at low frequencies. Moreover, coils also have a low spatial resolution, due to its millimeters range size. While coils measure magnetic flux, MR sensors measure magnetic field thus having a frequency independent sensitivity. Therefore, by adding MR sensors to the probe, its scope of detection increases, and also its spatial resolution, since MR sensors can have dimensions on the micrometer range. Other advantage of MR sensors is the fact that they are usually produced using thin film technology allowing high resolution and repeatability. In order to increase the number of MR sensors in the probe, CMOS microelectronic circuits will be included to perform multiplexing and therefore reducing the number of outputs. The CMOS circuit will also bias the MR sensors, and apply lownoise amplification and filtering. To cope with the new probe high data throughput, the system will also include an high performance Digital Signal Processing (DSP) unit. The DSP unit will be based on a Field-Programmable Gate Array (FPGA) and high speed and resolution data converters. A scalable processing architecture will explore high parallelism within the FPGA processing core to perform digital demultiplexing, filtering and demodulation of the multiple sensors signals. Also, the DSP unit will configure the gain, bandwidth and the sensors addressing mechanism by communicating with the microelectronic circuits. Results will be displayed in a Graphical User Interface (GUI) running on a computer connected with the developed system. Characterization and testing on real and relevant NDT applications will evaluate the new system performance. Acron / Ref LIQ-OPVs PTDC/CTM-NAN/1471/2012 Title Towards very efficient organic photovoltaic cells through utilizing liquid crystal phases as electron-acceptors Funding FCT/PTDC 286 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES Descript. We propose, as a solution to seek more efficient OPVs and reduce production costs, the exploitation of discotic liquid crystalline (LC) phases as alternative acceptors to fullerenes. Discotic LCs are excellent candidates for OPVs due to their good absorptivity in the visible spectrum and for being homeotropically aligned by annealing and surface effects. The LC phases will be designed to combine favourable characteristics, namely: high absorptivity where the solar emission is more intense, electron-acceptor character relative to poly(alkylthiophene)s, and ability to assemble in nanostructures with enhanced charge mobility. To ensure the morphological stability of the resulting LC supramolecular structures, they will be synthesised as cross-linkable materials. We will deal with two classes of disc-like materials, both recognized as good electron acceptors, and with tunable LUMO levels, from which new materials with LC properties will be derivatized: electron acceptors from the class of fluorenes (Fs) and the N,N´Dicyanoquinone Diimines (DCNQIs). Whereas DCNQIs have only been explored as crystalline conductive salts, electron-acceptors from the Fs class have never been prepared as liquid crystal materials. Our workplan includes: i) screening among known DCNQIs and Fs and selection of those with more favourable photophysical and electronacceptor character in relation to poly(alkylthiophene)s; ii) synthesis of new LC materials as derivatives of those exhibiting more promising properties; iii) investigation of their self assembly character and development of methodologies to build film morphologies including the donor component; iv) characterisation of the active layers in terms of photophysical properties; v) fabrication and characterisation of OPV cells.

Acron / Ref INTMARSIS CGL2013-42557-R Title Interoperability and implementation of autonomous marine platforms for seismic monitoring Funding Descript. The study of seismic activity has played a key role in increasing the understanding of the dynamics of the Earth and its internal structure. Variations in real time seismicity provides knowledge of the state of local and regional stresses in the short and medium term, essential information to study the potential seismic risk that may affect infrastructures and population located in the area . Seismic information is obtained indirectly from the knowledge of traveling time of seismic waves and their trajectories. For this, it is important to record these waves with different azimuths using seismic sensors. The resolution of these measurements depends on the coverage and number of sensors capable of recording these waves and their arrival times. On land, the resolution, and coverage is adequate at the regional level, and is relatively easy to be increased in specific cases using portable seismic stations (e.g. for microseismic studies). However, it is important to note that the dynamics of the lithosphere associated with the interaction of tectonic plates happens mostly in ocean basins and margins, yet the distribution of marine seismic stations is far from their equivalent in land, either because of the technological complexity related with the environment, or the difficulties to access the recorded data. Recent seismic activity, possible induced, in the Gulf of Valencia or the intense underwater seismic activity associated with the eruption of El Hierro (20112012) shows the importance of controlling the seismicity located in the sea that is not covered by the terrestrial monitoring networks. To overcome this problem, the INTMARSIS project will integrate different measurement and data communication 289 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES technologies in a new design with a buoy on surface and a seafloor seismometer. The integration of real time data generated by marine seismometers will be possible thanks to the development of wireless communication systems, the increasing potential for miniaturization of sensors, storage devices and data processing, which have opened the door to a new generation of distributed intelligent sensor networks that are connected by communication networks. To enable the exchange of instruments between different systems and platforms is necessary the standardization of these. Therefore, standardization should begin at the sensor level because this gives a good integration of the information flow. In observing systems with a limited number of instruments, it is always possible to individually integrate each instrument in the measurement system. However, in the future systems of heterogeneous observation and dynamic variable, this concept will not be practical. The joint efforts of the research team, and industrial EPOs with extensive experience in the various technological challenges of the project, will permit the design, construction and assembly of a new generation of interoperable marine seismometers that will delivered acquired information in real time. This will represent a significant advance over existing devices, decreasing the technological dependence and promoting the development of own technologies. Acron / Ref EvalTubes PEst-OE/EEI/LA0008/2013 Title Remaining Life Evaluation of Catalytic Furnace Tubes Funding FCT Descript. The objective of this paper is to evaluate from the output surface the damage of the catalytic tubes of the columns of the reformer furnaces in order to predict its remaining life. Catalytic tubes are the most critical components in reformer furnaces. Reformer furnaces are widely used in the petrochemical industry to produce hydrogen from hydrocarbons. It is in the radiant tubes containing a catalyst that the hydrogen production takes place, as a result of endothermic reactions between hydrocarbons (mostly methane) and water vapor. These reactions proceed at a temperature range between 800 and 900ºC and the working pressure in a reformer furnace is between 2 and 5 MPa. These are severe working conditions that cause structural damage in the tubes. It is necessary to develop methods for the inspection of tube degradation and for a realistic prediction of its residual life. Some analytical methods have been developed to estimate reformer columns service life or the time to failure, as the assessment of damage and advance planning of column replacement should be made to ensure that failures or unplanned shutdowns are avoided. However, direct methods to evaluate the probable extent of damage and remaining life in a particular furnace are always much more preferable. Nowadays, direct tests are performed destructively by examining metallographically the microstrutural changes and creep damage on a series of ring 290 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES samples cut along the length of single tube removed from the reformer furnace. The objective of this project is to project and implement an in-situ measurement system to inspect through a nondestructive testing (NDT) technique, based on eddy currents, reformer tubes damages to infer about its remaining life. The eddy current method is based on the excitation of the material with a time variable magnetic field. In this way, the electromotive force developed inside the material will give rise to electric eddy currents. These currents are related to the conductivity distribution of the body and exhibit certain patterns that can be predicted by measuring the total magnetic field in the vicinity of the material. In the presence of defects, such as cracks due material fatigue, the eddy currents deviate from its normal geometrical configuration, and this perturbation on the eddy currents can be sensed by magnetic sensors placed close to them. This technique enables not only the detection of cracks due to material fatigue but also the appearance of intermediate stages that are correlated with the micro-structural changes that occur during service. This project deals with a challenging problem very important for the petrochemical industry. It is to be developed in partnership with colleagues from the Laboratório de Ensaios Não Destrutivos, Corrosão e Soldadura from Universidade Federal do Rio de Janeiro. They shall provide us characterized samples taken from reformer furnace tubes with different damages and degradation. The work included within this proposal will complement their work on the failure analysis and remaining life assessment of the tubes based on the microstructural observations they perform using different techniques like light microscopy, scanning electron microscopy, transmission electron microscopy and diffraction and carried out within a research project supported by Petrobras. It is our belief that the success of this work in partnership would enable our participation in future projects now that the agreement with Instituto de Petróleo e Gás and Petrobrás is underway. This project besides its technical and scientific objectives is also focused on promoting nondestructive evaluation issues to young researchers. It is a multidisciplinary field of study, linking different areas of knowledge, which embraces issues like: (1) technology development; (2) image processing and recognition; (3) modeling and algorithms; (4) measurement techniques. In Portugal there are very few competencies within the nondestructive testing knowledge area in spite of the abundance of industrial relevance for them and as a result Portugal is losing competitiveness in a 600 million global market.

As such, the research activities involved concentrate on the synthesis of active organic materials, the study of the physicochemical properties of the active layer (components and blend), the morphological structure of the blend, and the electro-optical characterization of devices prepared from these blends 293 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES Acron / Ref GeTFun PIRSES-GA-2012-318986 Title GeTFun - Generalizing Truth-Functionality Funding EU/FP7 Descript.

Besides the abstract, model- and proof-theoretical aspects, the project will keep a strong focus in meaningful application areas where the complexity of the phenomena involved goes beyond the scope of standard approaches. The impact and relevance of the proposed line of work should accordingly be measured directly by its foundational character with respect to a better and deeper understanding of meaning in logics modeling complex phenomena and, of necessity, suitable general forms of compositional reasoning.

In this framework, Snecma is leading the Clean Sky SAGE2 activities, to study the development of an innovative concept based in a geared open rotor engine that will 294 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES end up as a breakthrough for the next 15 years, thanks to the improvements in the propulsive efficiency, without the penalties of any duct drag. Along with several engine subsystems and technologies that are being developed in the scope of SAGE2, conducted by several Clean Sky ITD leaders, Avio Propulsione Aerospaziale is responsible for the power gearbox, which is the focus of this bidding activity. As an innovative high efficiency power gearbox is being developed, it is very important to keep the tracking of as many early physical parameters as possible, in order to provide useful feedback data for design processes optimization; during operation, similar parameters will allow the aircraft to identify potential structural health problems, such as unexpected vibration, temperature and pressure variations, and metal debris in the oil. In this RTMGear activity, Active Space Technologies (AST) intends to develop a telemetric system based, as much as possible, in proved technologies, while Instituto de Telecomunicações (IT) will focus their research in innovative Surface Acoustic Wave (SAW) technologies for measuring temperature and strain in rotating parts. Acron / Ref QUTE-EUROPE 600788 Title QUTE-EUROPE – Quantum Technologies for Europe Funding EU/FP7 Descript. Research in Quantum Information and Communication Technologies (QICT) has since many years gained an important European dimension. The number of research groups active in the field as well as the number of publications testify to the vigorous and scientifically proliferate state of the community and show that QIPC research in Europe is well on par and highly competitive with comparable activities elsewhere in the world. The Coordination Action (CA) QUTE-EUROPE will continue to advance this European excellence via a structured approach towards the implementation of key topics such as a strategic vision, collaboration and dissemination. It will carry out a set of actions that are specifically targeted at coordination and cooperation within the QICT research community in Europe and beyond, as well as increasing the visibility of the field to the scientific global community, industries and the public at large. The CA will set up a work structure with the ultimate goal of making the research community and its scientific achievements internationally recognised and sustainable. This will guarantee that the expertise and the knowledge gained through the CA activities will be of benefit to the European QIPC research community, the global QIPC community and all involved stake holders in the field. 295 ANNUAL REPORT 2015 – BASIC SCIENCES AND ENABLING TECHNOLOGIES Acron / Ref MemoCIS IC1401 Title COST IC1401 Memristors - Devices, Models, Circuits, Systems and Applications (MemoCiS) Funding ESF/COST Descript. The invention of the “transfer resistor”, or “transistor” as it is know today, is considered to be the greatest invention of the 20th century, as it forms the basis of all electronic systems. The next technological revolution will come through self-organizing and selfprogramming circuits and systems, which are similar to biological brains in that they can learn to perform tasks. The recently rediscovered Memristor offers a computational substrate with plasticity, in which adaptive circuits can be efficiently implemented. This Action is aimed at bringing together researchers of different backgrounds to work in unison so as to overcome multidisciplinary barriers in the area of memristors. Bringing together device designers, device modelers, circuit theorists, analogue and digital designers, neuromorphic engineers and computation scientists will enable the defragmentation of current research efforts and is likely the to bring then next technological revolution. The creation of the hardware basis for future selforganizing/self-programming systems will really open up a wide range of application areas and new industries, e.g. humanoid robots to look after the elderly, self-driven vehicles etc. Acron / Ref REONA S01047 Title REONA - Reliability on Air Funding ADI/QREN Descript.
