Modélisation Mathématique Et Analyse Numérique

In this paper we introducé the Local Projection P° P-Discontinuous Galerkin finite elemente method (ÂI1P ° P -scheme) for solving numencally scalar conservation laws This is an exphcit method obtained by modifying the expltcit Discontinuous Galerkin method introduced by G Chavent and G Salzano [3], via a simple local projection based on the monotomcity-preserving projections introduced by van L...

Modélisation Mathématique Et Analyse Numérique

— This paper présents a new mixed finite element method for the computation of incompressible viscoelastic fluids flows. The decoupled computation of stresses and velocities is performed with an algorithm which involves a time approximation by alternating direction implicit algorithms. The method is of order two in time and allows fast calculation of stationary solutions. As finite éléments, we...

Our aim is to explain the links between innovation and interfirm network structure and dynamics. We therefore need to understand first the mechanisms that lead to the formation and evolution of real networks. Network analysis was conducted using Tetralogie software for network mapping and graph-theoretic concepts such as density and centrality. Knowledge at all times of the macroscopic environm...
