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/inter-system 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 trade-off 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 the feasibility of the proposed algorithms. We extend the FPGA infrastructure developed in the previous IT/CELCOP project for the envisioned heterogeneous network. Selected algorithms (the simplest ones) will be tested in this infrastructure. Besides these technical objectives we also aim and consider of high importance the following objectives,•Attract students for a career in R&D in the field of telecommunications. •Promotion of research collaborations between re...

Em Portugal a incerteza económica associada à contenção orçamental, a altos níveis de desemprego e a tendências de desequilíbrio social crescente têm sido o mote para o profundamento de uma reforma administrativa das funções sociais do Estado. Desde o despoletar da crise internacional e especialmente no período de gestão governativa sobre monitorização da TROIKA (2011 a 2014) o Estado diminuiu a sua presença num certo número de setores da vida social que se lhe incumbiam e que tinha a seu cargo, garante do serviço público aberto e oferecido a todos, sem distinção. Eficiência e racionalidade de “boas práticas de gestão” orientadas, no fundamental, pela redução de despesasão frequentemente os elementos a partir dos quais se tem vindo a avaliar a capacidade governativa de ajustamento ao novo contexto. Neste estudo a eficiência dos processos de reconfiguração do Estado e das Políticas sociais que vêm sendo preconizadas são examinados num confronto sistemático com as suas implicações na promoção de equidade e de bem-estar e qualidade de vida das populações abrangidas. Concretamente, analisam-se os efeitos da orientação para a diminuição do peso das funções sociais do Estado num aumento real de desigualdades sociais e na inversão de tendências que apontavam ganhos sociais relativos em áreas sensíveis de desenvolvimento humano e progresso social, como são a saúde, a educação, a segurança social e a participação cívica.

• Investigate theoretically and experimentally the potentials of new open resonators based on ENZ-type shields at microwaves.• Investigate nonlinear effects. • Extend to electronics our approach of having bound photonic states coupled to the continuum.

This project aims to provide an answer to societal challenges by providing an innovative Organisational Life Assistant (OLA), a virtual presence that supports instrumental activities relating to daily living needs of older adults allowing them to be more independent, self-assured and to have a healthier, safer and organized life, while facilitates caregivers by supporting them on offering high-quality assistance OLA will mediate and facilitate interaction (communication and collaboration) between senior citizens and their informal caregivers or other services or professionals, through technological devices such as standard computers, mobile devices (tablets) and home automation modules.   These ICT devices will be based on an innovative multimodal model, embracing various physical/healthy and cognitive characteristics of the older adults and will specifically oriented to increase the level of independence of the elderly, by supporting the possibility of carers’ assistance remotely and by improving the accessibility to existing services on the Web, such as shopping on-line services. Moreover, the OLA will also provide a personalized well-being and safety advices to older users in order to avoid unwanted age related health and safety situations at their own home. Such a well-being and safety advisor makes uses of a combination of collected user information (personal physical/health and cognitive characteristics) and user interaction information extracted through emotion recognition and various sensor settings.

A análise das desigualdades sociais constitui um dos mais importantes instrumentos para conhecer a atual realidade europeia. O presente projeto pretende contribuir para essa análise, através de um conjunto de contributos inovadores quer no plano teórico-conceptual, quer no plano operatório. A investigação assenta numa análise extensiva e comparativa apoiada em base de dados internacionais, nomeadamente o European Social Survey, o EU-SILC e outros. A análise dá relevo às intersecções sistémicas e multidimensionais entre os segmentos estruturais “classe-país” e as distribuições integradas de rendimento, escolaridade, género e idade no espaço social da Europa.
