Theoretical and numerical study of the stability of some distributed systems with dynamic boundary control, Étude théorique et numérique de la stabilité de certains systèmes distribués avec contrôle frontière de type dynamique

Mohamad Ali Sammoury

This thesis is devoted to the study of the stabilization of some distributed systems with dynamic boundary control. First, we consider the stabilization of the Rayleigh beam equation with only one dynamic boundary control moment or force. We show that the system is not uniformly (exponentially)…, Cette thèse est consacrée à l’étude de la stabilisation de certains systèmes distribués avec contrôle frontière de type dynamique. Nous considérons, d’abord, la stabilisation de l’équation de la poutre de Rayleigh avec un seul contrôle frontière dynamique moment ou force. Nous montrons que le…

Preparation and characterization of anorthite and hydroxyapatite from Algerian Kaolin and natural phosphate

H. Belhouchet, F. Chouia, M. Hamidouche, Anne Leriche

Different composite materials were prepared using kaolin (DD2) and natural phosphate. Several mixtures were used by varying the kaolin content from 20 to 80 mass %. All powders were mixed and grounded by ball milling and then pressed in cylindrical form. Finally, the green samples were sintered…

The Minkowski-Lorentz space for Computer Aided Design purposes

Jean-Paul Becar, Lionel Garnier, Lucie Druoton, Rémi Langevin, Laurent Fuchs, Géraldine Morin

This document deals with the Computer Aided Geometric Design with a short presentation of the Minkowski-Lorentz space. This space generalizes to R 5 the one used in the relativity theory. The Minkowski-Lorentz space oers a more intuitive writing of a sphere given by a point, a normal vector at the…

Modeling of MEMS Resonator Piezoelectric Disc Partially Covered with Electrodes

Ismail Naciri, Lahoucine Elmaimouni, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, Mohamed Rguiti, Tadeusz Gryba

The Legendre polynomial method has been extended to the modeling of MEMS resonator disc partially covered with electrodes. The disc has been divided into two areas: one with electrodes and the other without electrodes. For each area, The Maxwell equations and the piezoelectric constitutive…

Lagrangian submanifolds in the 6-dimensional nearly Kähler manifolds with parallel second fundamental form

Y. Zhang, Bart Dioos, Z. Hu, Luc Vrancken, X. Wang

In this paper, we study the Lagrangian submanifolds in the homogeneous nearly Kähler S3×S3 with parallel second fundamental form. We first prove that every Lagrangian submanifold with parallel second fundamental form in any 6-dimensional strict nearly Kähler manifold is totally geodesic. Then we…

Vibrational energy-harvesting performance of bio-sourced flexible polyamide 11/layered silicate nanocomposite films

M. Leveque, C. Douchain, Mohamed Rguiti, K. Prashantha, Christian Courtois, M.-F. Lacrampe, P. Krawczak

The energy-harvesting efficiency of melt processed polyamide 11 (PA11) films and its nanocomposites have been investigated as a function of filler type and content. In the present work, nanoclays have been used as structural modifiers in a PA11 matrix. The nanocomposites were prepared using layered…
