In recent decades, many dams have been built or are under construction. Due to the high demand for water and soil erosion, increasing the need for dam construction in different regions are quite tangible. In 1900 the number of large dams, did not exceed 50. But in the 1950s to 1986 the number of large dams (over 15 meters), more than 39,000 were counted. The 70s dams has been increasing develop...
Morning glory spillway is one of the spillways that used to passing of flood from high to low level. This spillway is used in the reservoir dams that are placed in narrow valleys and in many locations with high slope in reservoir walls. In the Morning glory spillways, the vortex flow can reduce discharge, discharge coefficient and the performance of spillway. The zigzag spillway, as another typ...
The separation efficiency and pressure drop of the dynamic separator cement particles can be affected by many factors, like structural type, geometric parameters, operating characteristics. In this paper, CFD modeling is applied to investigate fluid flow behavior industrial with different heights inner cone called vortex breaker. Simulations are based on RSM DPM models. A comparison original de...

Once a power system is established it is necessary to protect it from faults (whether internal or external). So we use some protecting and sensing device like circuit breakers, Relays, Fuses etc. Circuit breaker is a mechanical device capable of making, carrying and breaking currents under normal circuit conditions and also making, carrying for a specified time. This paper represents informatio...

This paper introduces a new type of discriminative subgraph pattern called breaker emerging subgraph pattern by introducing three constraints and two new concepts: base and breaker. A breaker emerging subgraph pattern consists of three subpatterns: a constrained emerging subgraph pattern, a set of bases and a set of breakers. An efficient approach is proposed for the discovery of top-k breaker ...
With the rapid development of arts of sensors and IT, on-line monitoring of circuit breaker is now desirable and practical for electric power utilities. This paper describes a set of overall on-line monitoring systems that was developed to control and monitor the condition of SF6 circuit breaker with different type of sensors and microcomputer based controller. The aim of the developed system i...
Letm and b be positive integers and let F be a hypergraph. In an (m, b) Maker-Breaker game F two players, called Maker and Breaker, take turns selecting previously unclaimed vertices of F . Maker selects m vertices per move and Breaker selects b vertices per move. The game ends when every vertex has been claimed by one of the players. Maker wins if he claims all the vertices of some hyperedge o...
