This paper focuses on the identifiability problem of hydrological system modelling, taking implicit rainfall-runoff models as a target for study i.e. those models whose structures are nonlinear functions of their parameters. Because most implicit models and objective functions are very difficult as regards analytical solution or for finding high-order derivatives, a numerical analysis method is...

Retrieval and citation of primary data is the important factor in the approaching e-science age. Solving the challenge of building a flexible but homogeneous bioinformatics information retrieval infrastructure to access and query the world life science databases is a crucial factor for an efficient building bioinformatics infrastructure. In this contribution, we demonstrate the use of nine feat...

Au Québec, la géopolitique n'a pas suscité, comme domaine de recherche, vifs débats épistémologiques en France ou ailleurs dans le monde. A croisée des écoles française et anglo-saxonne, québécoise a connu un développement progressif, avec quelques pionniers les années 1960, pour s'ancrer paysage disciplinaire géographie 1980. La sous-discipline d'abord été portée par enjeux géopolitiques liés ...

We propose a finite volume method on general meshes for the numerical simulation of an incompressible and immiscible two-phase flow in porous media. We consider the case that can be written as a coupled system involving a degenerate parabolic convection-diffusion equation for the saturation together with a uniformly elliptic equation for the global pressure. The numerical scheme, which is impli...

The aim of the paper is to study the analogies between the development of painting and the history of geometry. It starts with brief comments on geometrical aspects Renaissance painting, followed by analyses of geometrical aspects of mannerism, baroque, impressionism, and ends with discussion of cubism and abstract art. The paper represents a sequel to our paper History of Geometry and the deve...
