In an optical multiple-access system, overall system throughput efficiency and significant implementation costreduction would be achieved if many users could access a common optical channel at any time without control among users. Recently one such scheme, an optical orthogonal code division multipleaccess system (OOCDMA), was introduced by Salehi et al. 111-[6] for the case of no noise. In thi...

In this paper performance analysis of Doubly Fed Induction Generator under abnormal condition is analysed. In recent years, this series compensated transmission system will produce unwanted effect of sub synchronous resonance. Super Conducting Magnetic Energy Storage (SMES) provides an efficient damping for sub synchronous resonance that will enhance power system stability in addition to real a...

In this paper, transient stability improvement using bridge type fault current limiter (FCL) is presented in single machine infinite bus (SMIB) system with a double circuit transmission line. Three single-phase sets of the proposed FCL are installed at the beginning of feeder. The proposed FCL inserts an inductance and a resistance in the fault current pass. The insertion inductance and resista...

RÉSUMÉ. Nous proposons un schéma algorithmique générique original pour contrôler la granularité du parallélisme en cours d’exécution. Ce schéma est basé sur le couplage de deux algorithmes, l’un séquentiel, l’autre parallèle à grain fin. La génération de parallélisme n’est effectuée qu’en cas d’inactivité d’un processeur. Lors de l’exécution sur un nombre restreint ou variable de ressources, ce...

A Newton-Krylov unstructured flow solver is developed for higher-order computation of the Euler equations using an upwind scheme. The Generalized Minimal Residual (GMRES) algorithm is used for solving the linear system arising from implicit time discretization of the governing eqautions. An Incomplete Lower-Upper factorization technique is employed as the preconditioning strategy, and an approx...

Since the end of 2005 most of the plasma–wall interaction experiments on FTU have been focused on the possible use of liquid lithium as the plasma facing material. Liquid lithium limiter is an active method to deposit, during the plasma discharge, a lithium film on the walls with prolonged beneficial effects. Reliable operation with very clean plasmas, very low wall particle recycling, spontane...
