Anisotropic a posteriori error estimation for the mixed discontinuous Galerkin approximation of the Stokes problem

Emmanuel Creusé, Serge Nicaise

The paper presents a posteriori error estimates for the mixed discontinuous Galerkin approximation of the stationary Stokes problem. We consider anisotropic finite element discretizations, i.e. elements with very large aspect ratio. Our analysis covers two- and three-dimensional domains. Lower and...

Discrete compactness for a discontinuous Galerkin approximation of Maxwell's system

Emmanuel Creusé, Serge Nicaise

In this paper we prove the discrete compactness property for a discontinuous Galerkin approximation of Maxwell's system on quite general tetrahedral meshes. As a consequence, a discrete Friedrichs inequality is obtained and the convergence of the discrete eigenvalues to the continuous ones is...

Optimized piezoelectric sensor for a specific application : detection of Lamb waves

Mohamed Rguiti, Sébastien Grondel, Faysal El Youbi, Christian Courtois, Marc Lippert, Anne Leriche

This work is devoted to the development and the optimization of a new piezoelectric sensor using Lamb waves destined to aerospace structures health monitoring. In such systems, Lamb waves are usually excited and received by thin single piezoelectric transducers. One of the most critical tasks in...

Approximation par des B-Splines de solutions optimales pour des problèmes LQ : une estimation a posteriori de l’erreur

Philippe Auquiert, Wilfrid Perruquetti, Olivier Gibaru

Nous proposons une alternative à l’équation de Riccati lors de la résolution de systèmes linéaires quadratiques en contrôle optimale. Une transformation de l’équation d’état basée sur la forme de Brunoswski de ce système permet de mettre en évidence une représentation sous la forme de sorties dites...

New considerations about the fracture mode of PZT ceramics

Olivier Guillon, Dominique Perreux, Frédéric Thiebaud, Christian Courtois, Philippe Champagne, Anne Leriche, Jacques Crampon

Sintered bulk ceramics, such as PZT are brittle materials. This macroscopically implies a statistical distribution of the ultimate strengths, because defects, such as pores or cracks are responsible for the initiation of the specimen failure. Another aspect of this fracture phenomenon is the crack...

Ce rapport décrit les fouilles de Termez, dans la citadelle (céramique hellénistique, sépultures de l'époque islamique) ; à Tchingiz Tepe (fortifications, temple, four, protomé de lion) et à Payon Kourgane. Il traite aussi du bouddhisme en Bactriane., This report describes the excavations at Termez, in the citadel (Hellenistic ware, burial in the Islamic World) ; at Tchingiz Tepe (fortification, temple, kiln, lion's protome). It deals with the Bactrian buddhism.

In vitro studies of human and rat osteoclast activity on hydroxyapatite, b-tricalcium phosphate, calcium carbonate

Francine Monchau, A Lefèvre, Michel Descamps, A Belquin-Myrdycz C, P Laffargue, H F Hildebrand

Investigations on the ceramic degradation caused by osteoclasts are designed to assess osteoclast Á/ceramic interactions and to determine which ceramics are more suitable for use as bone substitute. This study investigated the resorptive activity of osteoclasts on ceramics presenting different...
