Énumération des permutations par nombre de marches

— A step in a permutation a: a2.. .aH isanatsuch thatai+] = af — 1 . Itis proved that the number M (n, k) of permutations with exactly k steps is given by M (n, k) = ( J d (n — k + \)i{n — k) where d{n) is the number of dérangements (permutations with every element displaced). INTRODUCTION Les propriétés combinatoires des permutations, notamment rémunération des permutations suivant le nombre d...

Condensés de textes par des méthodes numériques

Since information in electronic form is already a standard, and that the variety and the quantity of information become increasingly large, the methods of summarizing or automatic condensation of texts is a critical phase of the analysis of texts. This article describes Cortex a system based on numerical methods, which allows obtaining a condensation of a text, which is independent of the topic...

Vérification de l'identité par des données biométriques

This article presents the main idea of a Biometric Authentication System (BAS). We will briefly describe BIOMET database, constructed for this purpose and composed of five modalities: face, hand-shape, fingerprint, online signature and speech. We have used two user-friendly biometric modalities of this database to construct the unimodal the signature modality was fused with clean and noisy spee...

Analyse qualitative de la dynamique de réseaux de régulation génique par des modèles linéaires par morceaux

The functioning and development of living organisms is controlled by large and complex networks of genes, proteins, small molecules, and their interactions, so-called genetic regulatory networks. In this review we discuss a method for the qualitative modeling and simulation of genetic regulatory networks which is well-adapted to the current lack of precise and quantitative biological data. The ...
