RÉSUMÉ OF EXPERIMENTS IN AERODYNAMICS

Résumé Court

The glass transition is the dramatic dynamical slowdown one observes when cooling down a liquid or densifying a set of particles into an amorphous state. In this thesis we explore two distinct situations related to this phenomenology, mostly in the case of granular materials. In a first part we study the strongly non-linear response of an assembly of frictional grains under vibration when they ...

Résumé Motivation

Heterogeneity, at service and technology level, is one of the main characteristics of todays networks. The ever increasing offer of new services has changed not only the amount of traffic in the network but also its structure. As a result, traditional techniques for traffic prediction and classification are becoming obsolete. In the first part of the thesis, we address these two problems by mea...

Résumé Des Chapitres Chapitre 1. Introduction Générale

Semantic peer-to-peer systems are fully decentralized overlay networks of people or machines (peers) sharing and searching varied resources (documents, videos, photos) based on their semantic annotations using ontologies. In such systems, no user imposes to others his ontology but logical mappings between ontologies make possible the creation of a network of people in which personalized semanti...

Résumé de thèse

Cette thèse est consacrée à l’étude de divers problèmes de modélisation en élasticité non linéaire. Les deux premières parties portent sur la justification des modèles bidimensionnels de plaques non linéaires. La motivation est commune, mais les approches, développement asymptotique formel dans un cas, Γ-convergence dans l’autre diffèrent. Le dernier chapitre traite de la modélisation des solid...
