Electroactive polymers (EAP) consist of materials capable of changing dimensions and/or shape in response to electrical stimuli. Most EAPs are also capable of generating electrical energy in response to applied mechanical forces. These polymeric materials exhibit properties well beyond what conventional metal or plastic-based actuators can offer, including very high mechanical flexibility (can be stretched to twice their initial size), low density, a high grade of processability, scalability, microfabrication readiness and, in most cases, low cost. Micro-EAPs enable a new broad range of applications for which large strains and forces are desirable, and for which built-in intelligence is necessary. The main objective of the project will be the improvement of the career perspectives (in academia and in industry) of young researchers by training them at the forefront of research in the field of smart soft systems made of EAP microactuators for advanced miniaturized devices. The overall objective for the scientific programme is research and development of EAP materials and their integration for industrial applications. Special attention will be devoted to the development of microactuators. The field of smart materials is growing extremely fast. Materials whose stiffness and shape can be controlled, and that are capable of sensing their shape allow new classes of compliant complex systems. Through the MICACT programme, we hope to ensure that European researchers keep their leading role in this blossoming field, and to help them transition to industrial positions.

In this paper, the almost sure global well-posedness of the cubic non linear wave equation on the sphere is studied when the initial datum is a random variable with values in low regularity spaces. The result is first proved on the 3D sphere, thanks to the existence of a uniformly bounded in Lp basis of L2(S3) and then it is extended to ℝ3 thanks to the Penrose transform.

We will consider the resolution of the 3D non linear wave equation under the assumption of spherical symmetry on the euclidean space. For this purpose, we will build a non trivial measure on distributions such that there exists a set of full measurement onto which the flow is globally defined. We will then discuss different properties of the solutions. © 2013 Copyright Taylor and Francis Group, LLC.

The modified algebraic Bethe ansatz, introduced by Crampé and the author [8], is used to characterize the spectral problem of the Heisenberg XXZ spin-1/2 chain on the segment with lower and upper triangular boundaries. The eigenvalues and the eigenvectors are conjectured. They are characterized by a set of Bethe roots with cardinality equal to N the length of the chain and which satisfies a set of Bethe equations with an additional term. The conjecture follows from exact results for small chains. We also present a factorized formula for the Bethe vectors of the Heisenberg XXZ spin-1/2 chain on the segment with two upper triangular boundaries. © 2015 The Author.

We propose a scheme allowing us to observe the evolution of a quantum system in the semiclassical regime along the paths generated by the propagator. The scheme relies on performing consecutive weak measurements of the position. We show how "weak trajectories" can be extracted from the pointers of a series of devices having weakly interacted with the system. The properties of these weak trajectories are investigated and illustrated in the case of a time-dependent model system. © 2012 American Physical Society.

An extension to the enhanced serial generalized bit-flipping decoding algorithm (ES-GBFDA) of non-binary LDPC codes by introducing soft information in the check node operation. The application not only considers the most reliable symbol in the syndrome computation, but also takes at least the second most reliable symbol of each incoming message into account. An extended information set is available for the parity-check node update and this allows introducing the concept of weak and strong votes performed by the check node unit. Each variable node can receive two kinds of votes, whose amplitudes can be tuned to the reliability of the syndrome that produces the vote.

Existing research suggests that political participation and European orientation of young people depend on how they experience influence and involvement at local level. This reflects that individuals need the experience of self-efficacy to engage in wider communities. Research also reveals that only few young people engage in formalised participation (parties, trade unions, or youth councils) as these are not flexible enough for individualised concerns, biographies and life styles and they reflect patterns of social inequality. The project Spaces and Styles of Participation (PARTISPACE) starts from the assumption that all young people do participate while not all participation is recognised as such. The study asks for the different ways in which young people participate in decisions which concern them and, in general, the life of their communities. How do 15- and 30-year-olds engage with the public in formal, non-formal and informal settings and how is this supported or inhibited by local youth policies and youth work? The countries involved Bulgaria, France, Germany, Italy, Sweden, Switzerland, Turkey and the UK secure contrasting contexts of young peoples growing up as well as differing orientations towards Europe. The design of PARTISPACE includes: National research literature reviews and policy analysis; Analysis of European Social Survey data on young peoples participatory orientations; Local case studies in one major city per country including expert interviews, focus groups discussions, city walks and biographical interviews with young people, ethnographic case studies of formal, non-formal, and informal participatory spaces. Activating and supporting participatory action research by young people themselves. The analysis relates local constellations with national and European patterns and discourses of youth participation. Findings are constantly discussed with representatives of the youth sector at local and European level.
