Central WENO schemes for hyperbolic systems of conservation laws

We present a family of high-order, essentially non-oscillatory, central schemes for approximating solutions of hyperbolic systems of conservation laws. These schemes are based on a new centered version of the Weighed Essentially Non-Oscillatory (WENO) reconstruction of point-values from cell-averages, which is then followed by an accurate approximation of the fluxes via a natural continuous ext...

Dynamic Fractional Resource Scheduling vs. Batch Scheduling

We propose a novel job scheduling approach for homogeneous cluster computing platforms. Its key feature is the use of virtual machine technology to share fractional node resources in a precise and controlled manner. Other VM-based scheduling approaches have focused primarily on technical issues or on extensions to existing batch scheduling systems, while we take a more aggressive approach and s...

Le traite de l’OMPI sur le droit d’auteur de 1996 est venu completer et mettre à jour la convention de Berne. Il a, dans une large mesure, reussie d’atteindre ses objectifs surtout pour; l’adoption des compilations de donnees sous quelque forme que ce soit, et de logiciel comme creations intellectuelles; la precision du droit de location pour les auteurs de progra...

Buffer Management Scheme for IP Differentiated Services

The demanding quality of service needs of research, education and commercial network service providers require new services in current “best-effort” Internet architecture. The Internet must enable applications that demand specific services to profit from a set of differentiated traffic classes, which support either relative or absolute types of quality of service, or both. This diploma thesis f...
