Microwave sintering of Ge-doped In2O3 thermoelectric ceramics prepared by slip casting process

E. Combe, E. Guilmeau, Etienne Savary, S. Marinel, R. Cloots, R. Funahashi, F. Boschini

Ge doped In2O3 bulks were prepared by dry uniaxial compaction or slip casting shaping methods followed by a conventional or microwave sintering. Density of slip casted Ge doped In2O3 samples after conventional sintering reaches bulk density close to the theoretical one thanks to an optimized…

Study of the stability of a certain systems of coupled wave equations and of the Rayleigh beam equation on bounded and unbounded domains, Étude de la stabilité de quelques systèmes d'équations des ondes couplées sur des domaines bornés et non bornés

Maya Bassam

The thesis is driven mainly on indirect stabilization system of two coupled wave equations and the boundary stabilization of Rayleigh beam equation. In the case of stabilization of a coupled wave equations, the Control is introduced into the system directly on the edge of the field of a single…, La thèse est portée essentiellement sur la stabilisation indirecte d’un système de deux équations des ondes couplées et sur la stabilisation frontière de poutre de Rayleigh.Dans le cas de la stabilisation d’un système d’équations d’onde couplées, le contrôle est introduit dans le système…

Ferroelectrics, piezoelectric, and Impedance spectroscopy characterizations of CuO doped (Na_0.52K_0.44)(Nb_0.9Sb_0.06)O₃–0.04LiTaO₃ lead free ceramics

M. Saidi, K. Khalfaoui, Ahcène Chaouchi, Sophie d'Astorg, Mohamed Rguiti, Christian Courtois

CuO was used to reduce the sintering temperature of (Na0.52 K0.44)(Nb0.9 Sb0.06)O3 –0.04LiTaO3 (NKNSLT) piezoelectric ceramics. XRD analysis reveals the formation of single phase perovskite structure. SEM has been used to investigate the grain morphology of the material. Impedance plots have been…

Stability analysis of a class of switched linear systems on non-uniform time domains

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai

This paper deals with the stability analysis of a class of switched linear systems on non-uniform time domains. The considered class consists of a set of linear continuous-time and linear discrete-time subsystems. First, some conditions are derived to guarantee the exponential stability of this…

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…

Remarks on the uniqueness for quasilinear elliptic equations with quadratic growth conditions

David Arcoya, Colette De Coster, Louis Jeanjean, Kazunaga Tanaka

In this note we present some uniqueness and comparison results for a class of problem of the form (0.1) −Lu = H(x, u, ∇u) + h(x), u ∈ H1 0 (Ω) ∩ L∞(Ω), where Ω ⊂ R N , N ≥ 2 is a bounded domain, L is a general elliptic second order linear operator with bounded coefficients and H is allowed to have…
