We study the existence of (distribution/viscosity) solutions of a singular parabolic/Hamilton-Jacobi coupled system. Our motivation stems from the study of the dynamics of dislocation densities in a crystal of finite size. The method of the proof consists in considering a parabolic regularization of the system, and then passing to the limit after obtaining some uniform bounds using in particula...

Thème Protection de la vie privée à base d'agents dans un système d'e-learning Résumé Les systèmes d'e-learning visent à offrir un accès facile et permanent aux ressources pédagogiques mises en ligne. En effet, les systèmes d'e-learning sont dotés de capacités d'adaptation des contenus et des processus d'apprentissage selon le profil de l'apprenant. Les techniques d'adaptation utilisent des méc...

Substance Use Disorder (SUD) is a serious public health problem in India. The present study was planned to study the socio-demographic, clinical correlates and predictors of adverse outcomes in all new patients attending the De-addiction clinic in a tertiary hospital in Eastern India. All new patients visiting the De-addiction clinic were assessed and interviewed. Four groups were made viz Alco...

A number of studies show that students with no or little domain knowledge learn less from hypertext than from ’conventional‘ text, despite the cognitive plausibility that is attributed to hypertext. In order to improve the effectiveness of hypertext as an instructional device, we designed a hypertext program that shares many features with Schank's Goal-Based Scenarios (GBS), in particular an au...

The Computational Geometry Algorithms Library Cgal currently provides packages to compute triangulations in R and R. In this paper we describe a new design for the 3D triangulation package that permits to easily add functionality to compute triangulations in other spaces. These design changes have been implemented, and validated on the case of the periodic space T. We give a detailed descriptio...
