L’inclinaison Moyenne Des Orbites Des Comètes Sur La Figure De La Terre Et Sur Les Fonctions

One of the most extraordinary phenomena which the system of the world offers to us is the movement of the planets and of their satellites in the same sense and very nearly in the same plane; if we picture to ourselves in fact all these stars describing from west to east some nearly circular orbits and very little inclined to the ecliptic, while the comets seem to be moved indifferently in every...

Déploiement à grande échelle de la voix sur IP dans des environnements hétérogènes. (Large scale VoIP deployment over heterogeneous environments)

In this thesis, we focus on large scale Voice over IP (VoIP) deployment over heterogeneous Internet environments. We first present an overview of VoIP coding and transmission mechanisms. Then, we investigate performance limitations in the case of a large number of VoIP flows transported over wired Internet links between peer VoIP gateways. We address, in the first part of the thesis, the need t...

Sur La Description Des Formations De . . .

We are interested in nite-time blow-up phenomena for heat equations of the type: @u @t = u+ jujp 1u (1) where u : (x; t) 2 RN [0; T )! R, 1 < p, (N 2)p < N + 2. We rst construct for (1) a solution u which blows-up in nite time T at only one blow-up point x0 2 RN , and describe completely its blow-up pro le (or asymptotic behavior). This construction is based on a priori estimates' technique whi...
