Neutrons et matériaux : introduction

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...

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...

Contrôle de santé des matériaux et structures par analyse de la coda ultrasonore

The Coda Wave Interferometry (CWI) analysis serves to monitor the variation of propagation velocity in a heterogeneous medium with high precision (10−3% in relative terms). In combination with acoustoelastic theory, this type of analysis offers an NDT method for stress evaluation and/or damage detection. Since the CWI method is intended to evaluate extreme levels of accuracy, the presence of bi...

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

Gian-Marco Rignanese Unité de Physico-Chimie et de Physique des Matériaux

The aim of this four-day workshop is to assess the present status, the latest achievements and future perspectives of first principles approaches to the study of spectroscopic properties of solids, nanostructures, systems with increasing complexity, and materials of technological and biological interest. More specifically, this workshop will offer the opportunity to take a look back on ten year...
