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...

Isotropic and anisotropic error estimation of the mixed finite element method for second order operators in divergence form

Serge Nicaise, Emmanuel Creusé

This paper presents an a posteriori residual error estimator for the mixed FEM of second order operators using isotropic or anisotropic meshes in $R^d$, $d$=2 or 3. The reliability and efficiency of our estimator is established without any regularity assumptions on the solution of our problem.

Segmentation of complex geophysical structures with well data

Christian Gout, Carole Le Guyader

In many problems of geophysical interest, when trying to segment images (i.e., to locate interfaces between different regions on the images), one has to deal with data that exhibit very complex structures. This occurs, for instance, when describing complex geophysical images (with layers, faults...

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...
