Simplification des cartes géographiques par minimisation de la déformation locale

In cartography, the geographic regions are usually represented using regular dense maps corresponding to heights values associated with the nodes of a regular grid of R2. The simplification of such maps is an absolute requirement in order to make storage, simulation and display possible. In this Note, we propose a new simplification method based on a measure of the local deformation of the surf...

Une caractérisation des rétractes absolus de voisinage

We prove that a metric space is an ANR if, and only if, every open subset of X has the homotopy type of a CW-complex.

Réification des schémas de conception : une expérience

Although design patterns are becoming increasingly popular as a way to describe solutions to general design problems, question about their integration in language (reification or language support) stays an open question. In this article, after identifying the implementation problems and presenting some approaches, we show how FLO’s connectors allows for the representation and implementation of ...

Une généralisation automorphe des nombres de Stirling

Let [n] be theset {1,2, *.. , n> and CT a given permutation in S,, the symmetric group on [n]. The (unsigned) Stirling numbers of the first kind enumerate the permutations on En] with k cycles and those of the second kind give the number partitions of [n] having k blocks. In this paper we compute the number of permutations on [n] with k cycles and the number of partitions on [n] having k blocks...
