Improved Performance of Piezoelectric Transformer Mode Thickness by Nonlinear Methods

Aïda Chérif, Djamila Zehar, Khalissa Behih, Mohamed Rguiti

During these last years, the demand of miniaturized voltage transformers increased with the fast multiplication of portable equipment's. The miniaturization of the electromagnetic transformer is more difficult. An interesting solution consists of the use of the piezoelectric transformer of...

Blow–up for nonlinear Maxwell equations

Piero d'Ancona, Serge Nicaise, Roland Schnaubelt

We construct classical solutions to the nonlinear Maxwell system with periodic boundary conditions which blow up in H(curl). A similar result is shown on the full space. Our construction is based on an analysis of a shock wave in one space dimension.

Flat Almost Complex Surfaces in the Homogeneous Nearly Kähler S3×S3

Bart Dioos, Haizhong Li, Hui Ma, Luc Vrancken

By employing a nice adapted frame we prove a Bonnet-type existence and uniqueness theorem for almost complex surfaces in the homogeneous nearly Kähler manifold S3×S3. The proof uses a local correspondence between almost complex surfaces in S3×S3 and surfaces in R3 that satisfy the Wente H-surface...

Flat almost complex surfaces in the nearly Kähler S3 × S3

Luc Vrancken

In this talk we show how to study almost complex submanifolds of S3 × S3. Compact 6-dimensional non-K¨ahler nearly K¨ahler manifolds do not admit 4-dimensional almost complex submanifolds, so the almost complex submanifolds are surfaces. Previously, a classification of the totally geodesic almost...

Comparison of Numerical Error Estimators for Eddy-Current Problems Solved by FEM

R. Tittarelli, Y. Le Menach, F. Piriou, Emmanuel Creusé, Serge Nicaise, J.-P. Ducreux

In the domain of field computation with the finite-element method, choosing the mesh refinement is an important step to obtain an accurate solution. In order to evaluate the quality of the mesh, a posteriori error estimators are frequently used. In this paper, we propose to analyze and to compare...

Radiative heating of a glass plate: the semi-discrete problem

Luc Paquet

In a preceding paper (MSIA, 2012), we have studied the radiative heating of a glass plate. We have proved existence and uniqueness of the solution. Here, we want to study the semi-discrete problem and to prove a priori error estimates. Previously, in that purpose, we have to study the regularity of...

Influence de l'architecture macroporeuse en phosphate de calcium sur le comportement cellulaire in vitro, The influence of a calcium phosphate macroporous architecture on cellular behavior in vitro

Shaan Chamary

Les phosphates de calcium tels que le β-TCP sont utilisés depuis des décennies comme substitut osseux synthétique. Leurs bonnes propriétés chimiques et leur comportement analogue au tissu osseux in vivo et in vitro peuvent être améliorés par la technique de mise en forme employée. Il est aujourd..., Calcium phosphates such as β-TCP have been used for decades as synthetic bone substitutes. Its good chemical properties and its similar behavior to that of the bone in vivo and in vitro can be enhanced by the chosen shaping method. It is nowadays largely accepted that an optimized porous...
