Application of the method of characteristics to the dam break wave problem Application de la méthode des caractéristiques au problème de l’onde de rupture de barrage
In dam break waves, the surge front is a sudden discontinuity characterized by extremely rapid variations of flow depth and velocity. In this study, simple analytical solutions for instantaneous dam break wave are developed using the method of characteristics. The solutions are obtained for initially dry horizontal and sloping channels with turbulent motion, and they are compared with several d...
متن کاملRehabilitation of Old Naga-hammady Barrage Bridge
When the Old Naga Hammady Barrage has been constructed in 1930, it had a navigation lock on the western side of the barrage. In 1993, a new navigation lock has been constructed in the western side of the old lock. Each lock has a movable bridge to allow the high ships to pass from north to south and vice versa. The bridge of the new navigation lock is suffering from technical problems pampering...
متن کاملetude de lespace colonial dans un barrage contre le pacifique, onitsha et la jalousie
la notion de l’espace recouvre beaucoup des champs de la littérature surtout les sciences humaines. l’espace colonial se définit comme une cohésion de la géographie et de la politique étant lié aux évènements politiques et historiques des époques coloniales de la france et devient le reflet des points de vues et le style d’écrire de l’auteur. dans ces œuvres étudiés de cette recherche, la colon...
15 صفحه اولBARRAGE - Data Storage in BAR Model
Peer-to-peer networks have emerged as a relevant architecture for executing scientific computations. However, this kind of networks poses several problems. This thesis addresses the problem of data storage in a peer-to-peer architecture. We consider several distinct behaviors of the participating nodes. To deal with this variety, we use the BAR model, that comprises byzantine, rational, and alt...
متن کاملMechanisms of retroaxonal barrage firing in hippocampal interneurons.
We recently described a new form of neural integration and firing in a subset of interneurons, in which evoking hundreds of action potentials over tens of seconds to minutes produces a sudden barrage of action potentials lasting about a minute beyond the inciting stimulation. During this persistent firing, action potentials are generated in the distal axon and propagate retrogradely to the soma...
