A new technique is presented for the numerical solution of quasi-one-dimensional, vibrational and chemical nonequilibrium nozzle flows including nonequilibrium conditions both upstream and downstream of the throat. This new technique is a timedependent analysis which entails the explicite finite-difference solution of the quasi-one-dimensional unsteady flow equations in steps of time, starting ...

— We give an explicit upper bound for the residue at s = 1 of the Dedekind zeta function of a totally real number field K for which ζK(s)/ζ(s) is entire. Notice that this is conjecturally always the case, and that it holds true if K/Q is normal or if K is cubic. Résumé (Bornes supérieures explicites pour les résidus en s = 1 des fonctions zêta de Dedekind de corps de nombres totalement réels) N...

— In this paper we consider a Schrödinger equation on the circle with a quadratic nonlinearity. Thanks to an explicit computation of the first Picard iterate, we give a precision on the dynamic of the solution, whose existence was proved by C. E. Kenig, G. Ponce and L. Vega [15]. We also show that the equation is well-posed in a space H(T) which contains the Sobolev space H(T) when p ≥ 2. Résum...

Considering the fact that academic curricula asks of students to perform better in an ever increasing information world and to be able to solve problems efficiently, this study was aimed at verifying if students will develop metacognition, the ability to reflect on one’s own cognitive processes to a significant degree, after receiving a short term training in concept-mapping, an information org...

Dans cet article, nous présentons un modèle cognitif-écologique du comportement agressif et de son développement. Ce modèle souligne le rôle des processus cognitifs qui orientent le comportement et explicite à la fois leur mode de développement dans le temps et selon les contextes et leurs influences dans ces mêmes contextes. Le point de départ du modèle est la reconnaissance de la nature tantô...

— The solutions offixed-point équations for generalized (infinité) mords have previously been obtained asfrontiers of infinité trees. An algorithm is given which computes an explicit solution using a shuffle opération on words. This solution can be proven equal to the previous one so that the structure of the frontier s of infinité trees is completely analyzedfor those context-free grammars whi...

In this text we are interested in spectral properties of discrete Laplace operators deened on lattices based on nitely-ramiied self-similar sets. The basic example is the lattice based on the Sierpinski gasket. We introduce a new renormalization map which appears to be a rational self-map of a compact complex manifolds. We relate some characteristics of its dynamics with some characteristics of...

— The Fourier transform of a weighted Dirac comb of beta-integers is characterized within the framework of the theory of Distributions, in particular its pure point part which corresponds to the Bragg part of the diffraction spectrum. The corresponding intensity function on this Bragg part is computed. We deduce the diffraction spectrum of weighted Delone sets on beta-lattices in the split case...

One foundation of the model driven engineering (MDE) is to separate the modelling application description from its technological implementation (i.e. platform). Some of them are dedicated to the system execution. Hence, one promise solution of the MDE is to automate transformations from platform independent models to platform specific models. Little work has explicitly described platform charac...

Depuis les prévisions d’Adorno et Horkheimer à propos de la Kulturindustrie, dimension idéologique l’art est étroitement pensée articulée aux conditions matérielles sa production diffusion. La tâche des artistes résiderait ainsi dans recherche d’un style, compris non plus comme un travail du fond forme interne l’objet d’art, mais positionnement spécifique face industries culturelles : celui rés...
