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…

Osteoblastic cells colonization inside beta-TCP macroporous structures obtained by ice-templating

Edwige Meurice, Franck Bouchart, Jean-Christophe Hornez, Anne Leriche, D. Hautcoeur, Véronique Lardot, Francis Cambier, M.H. Fernandes, F. Monteiro

A casting method based on ceramic slurry ice-templating was used to create beta-tricalcium phosphate anisotropic oriented macroporous scaffolds. The freeze-casting method produces tubular interconnected pores with ellipsoidal shape. The tubular porosity structure is supposed to enhance cell…

Bioactive oxynitride glasses

Ahmed Bachar, Cyrille Albert-Mercier, Arnaud Tricoteaux, Anne Leriche, Claudine Follet-Houttemane, Stuart Hampshire

The low mechanical strength of bioactive glasses restricts their use to non load-bearing applications. One way to increase strength of glasses is to introduce nitrogen into the silicate network. Oxynitride bioactive glasses in the SiO2–CaO–Na2O–Si3N4 system were successfully prepared. Structural…

The distance of an eigenvector to a Krylov subspace and the convergence of the Arnoldi method for eigenvalue problems

Mohammed Bellalij, G. Meurant, Hassane Sadok

We study the distance of an eigenvector of a diagonalizable matrix A to the Krylov subspace generated from A and a given starting vector v. This distance is involved in studies of the convergence of the Arnoldi method for computing eigenvalues. Contrary to the previous studies on this problem, we…

Thermal conductivity of ceramic/metal composites from preforms produced by freeze casting

D. Hautcoeur, Yannick Lorgouilloux, Anne Leriche, M. Gonon, B. Nait-Ali, D.S. Smith, Véronique Lardot, Francis Cambier

Porous alumina and zirconia preforms, processed by ice templating, have been used to manufacture ceramic/metal composites by aluminium alloy infiltration. The aim of the present work is to study the influence of the ceramic material nature and of the initial porous structure on the thermal…
