Courbes hyperelliptiques à multiplications réelles et une construction de Shih

Let r and p be distinct prime numbers, let K = Q(cos 2π r ), and let F be the residue field of K at a place above p. When the image of (2 − 2 cos 2π r ) in F is not a square, we describe a geometric construction of a regular extension of K(t) with Galois group PSL2(F). This extension corresponds to a covering of P/K of “signature (r, p, p)” in the sense of [3, sec. 6.3], and its existence is pr...

Modélisation et Animation de Matériaux Hautement Déformables en Synthèse d'Images

In this thesis, we are dealing with computer graphics modeling and animation of highlydeformable materials. Our work is aimed at creating virtual physically-based models of mat-ter, able to automatically deform due to interactions with the environment. Coping withlarge deformation is known to be time consuming, so efficiency and visual quality are thekey issues as they can o...

Introduction a l'etude de salmonella et des salmonelloses en Iran

Physique et chimie des matériaux

The aim of this thesis is the investigation of the spectroscopic properties and the electronic structure of vanadium in minerals with a geological and/or technological interest. V K-edge HERFD-XAS experiments were combined with a theoretical determination of the measured spectra. Two approaches were complementary used to calculate the spectra: an ab initio approach and a multielectronic one. Th...

Construction automatique d'adaptateurs guidée par une ontologie pour l'intégration de sources et de données XML

This paper deals with integration of XML heterogeneous information sources into an information server according to an approach combining mediation and data warehousing. A schema, or ontology, is used to access to the external sources and also to the local data. We propose a unified method based on such an ontology able to achieve the two kinds of integration. Our contribution is twofold. First,...
