Développement de capteurs piézoélectriques interdigités flexibles pour la caractérisation ultrasonore des revêtements, Development of flexibles interdigitated piezoelectric sensors for ultrasonic charaterization of coatings

Rafatou Takpara

Ce travail porte sur la réalisation de capteurs interdigités (IDT pour InterDigital Transducer) sur des supports piézoélectriques. L’enjeu est double puisqu’il s’agit premièrement de disposer de capteurs efficaces pour générer des ondes de surface acoustiques (SAW pour Surface Acoustic Wave) afin…, This work deals with the realization of interdigital sensors (IDT for InterDigital Transducer) on piezoelectric substrates. There is a dual challenge since firstly, the aim is to have efficient sensors to generate surface acoustic waves (SAW) in order to characterize the quality of the coatings and…

Comparison of Conventional and Microwave Sintering of Bioceramics

Anne Leriche, Etienne Savary, Anthony Thuault, Jean-Christophe Hornez, Michel Descamps, Sylvain Marinel

The presence of a susceptor reduces the benefits of microwave heating as it screens to a large extent the microwave fields; therefore, the potential microwave effect on the final microstructures of the sintered samples is lowered. This paper shows that, because of the high microwave coupling of…

Consensus for linear multi-agent system with intermittent information transmissions using the time-scale theory

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai

This paper investigates the consensus problem for linear multi-agent system with fixed communication topology in the presence of intermittent communication using the time-scale theory. Since each agent can only obtain relative local information intermittently, the proposed consensus algorithm is…

Superlinear critical resonant problems with small forcing term

Mabel Cuesta, Colette De Coster

We prove the existence of solutions of a class of quasilinear elliptic problems with Dirichlet boundary conditions of the following form $$\begin{aligned} \left\{ \begin{array}{l@{\quad }l} Lu= g(u) -f &{} \hbox { in } \quad \Omega ,\\ u\in X, \end{array} \right. \end{aligned}$$ where \(\Omega…

Linearization of algebraic structures via functor calculus

Manfred Hartl

As the result of a long optimization process in categorical algebra, the notion of semi-abelian category allows for developing highly non-trivial algebraic theory in a very general framework which encompasses almost all algebraic structures usually studied, and even certain types of objects having…

Derivatives in Noncommutative calculus and deformation property of quantum algebras.

Dimitri Gurevich

The aim of my talk is twofold. First, I introduce analogs of (partial) derivatives on certain Noncommutative algebras, including some enveloping algebras and their ”braided versions”. Second, I discuss deformation property of some quantum algebras and show that contrary to a commonly held view the…

Bounding matrix functionals via partial global block Lanczos decomposition

Mohammed Bellalij, Lothar Reichel, G. Rodriguez, Hassane Sadok

Approximations of expressions of the form If:=trace(WTf(A)W), where A∈Rm×m is a large symmetric matrix, W∈Rm×k with k≪m, and f is a function, can be computed without evaluating f(A) by applying a few steps of the global block Lanczos method to A with initial block-vector W. This yields a partial…
