Sur des suites de racines dont la somme des termes est nulle

Estimation automatique de la distribution des sens de termes

In order to promote the usage of the natural language in information systems, it seems interesting to obtain lexical data allowing a satisfactory lexical disambiguation. The distribution of word senses is one such important type of data, but still is uneasy to obtain. We are currently developing a system for analysing thematics aspects of texts and undertaking word sense disambiguation based on...

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...

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...

Impact du changement d'échelle sur l'étude des causes des feux de forêts du sud-est de la France

The Modifiable Areal Unit Problem (MAUP) is a well-known issue related to the influence of the spatial support on statistical observations. It occurs when different spatial units making different spatial partitions are used and when the resulting measures vary according to those partitions. In this paper, we first draw a state of the art. Considering the particular problem of (up)scaling, we pr...
