This paper discusses several issues in the numerical modelling of atmospheric flow which have been left unresolved. These include the influence of partial model resolution of features that are represented in a model by only a few grid points and the implication of this inadequacy in terms of the parametrization of subgrid-scale processes. As a result of nonlinear interactions, this lack of reso...

The fatty acid (FA) content of fish is generally said to reflect fatty acid composition of the diet. In fact, incorporation of FA into tissues is modulated by various metabolic factors, and final composition will depend upon the initial FA content, cumulative intake of dietary fatty acids, growth rate and duration. Analysis of time course of changes in FA composition should be easier with anima...

In this paper, a new method for reconstruction of 3D segments from multiple images in urban areas environment is presented. Compared to previous algorithms, this one performs the matching of 2D segments in the Object Space through a sweep plane technique, thus avoiding the combinatorial exploration of all possible correspondences and handling images in a symmetric way. Furthermore, a method for...

Last years have seen the emergence of the service oriented architecture (SOA) designed to facilitate the creation, the publication, the networking and the reuse of applications based on services. Web services are the most important realization of the SOA architecture. They are self descriptive and modular entities which provide a simple model of programming and application deployment. Web servi...

— The normalized configuration entropy, based on the theory of information, when applied to the image of heterogeneous media, points out a characteristic length of the disorder, `opt, at which we calculate the optical properties. The models we propose make a partition of the image between percolated and non percolated cells of size `opt, in which we calculate effective dielectric functions. Two...

This paper deals with aquatic ecosystem model in estuaries context. These systems are described with functional organizations which are producers, consumers and decomposers. We use a hierarchical representation which is based on compartmental model. The different compartments exchange various fluxes of their global components, like oxygen for example, as well as fluxes of population individuals...

RÉSUMÉ. Les documents XML et les données semi-structurées peuvent être représentées par des graphes étiquetés. Dans cet article, nous établissons un lien direct entre ces graphes de données et les modèles d’un langage de la logique multi-modale hybride. Ce lien est ensuite exploré dans deux directions. Tout d’abord, nous nous intéressons à l’expression de contraintes d’intégrité sur des données...
