Grid computing systems are increasingly growing importance in the present world with advances in the network technology. Grids are composed of many geographically disturbed resources, each having its own administration domain. Grid computing involves decentralized heterogeneous, geographically distributed resources that can work on a job together. Since the resource availability is dynamic in n...

This paper presents how and why to unify load sharing and fault tolerance facilities. A realization of a fault tolerant load sharing facility, GATOSTAR, is presented and discussed. It is based on the integration of two applications developed on top of Unix: GATOS and STAR. GATOS is a load sharing manager which automatically distributes parallel applications among heterogeneous hosts according t...

It is widely accepted that transient stability is an important aspect in designing and upgrading electric power system. The objective of this paper was to investigate and understand the stability of power system In this paper, modelling and transient stability analysis of IEEE 9 bus system was performed using POWER WORLD SIMULATOR. The load flow studies were performed to determine pre-fault con...

Fault recovery of distribution network is realized by operating switches to change topological structure of the network. The final destination of fault recovery is power loss minimization, fault isolation and power load transfer. This article has built the mathematical model of fault recovery considering constraints of node voltage, line capacity and power flow balance. The objective function i...

Process allocation is important for fault-tolerant multi-computer systems since it directly aaects the performance and dependability of the system. In this paper , we consider load-balancing process allocation for fault-tolerant systems that balances the load before as well as after faults start to degrade the performance of the system. We show two schemes to tolerate multiple faults in the pas...

In a fault-tolerant parallel computer, a functional programming model can facilitate distributed checlq3ointing, error recovery, load balancing, and graceful degradation. Such a model has been implemented on the Draper Fault Tolerant Parallel Processor (FTPP). When used in conjunction with the FrPP's fault detection and masking capabilities, this implementation results in a graceful degradation...

ABSTRACT Motor current signature analysis has been successfully used for fault diagnosis in induction motors. However, this method does not always achieve good results when the speed or the load torque is not constant, because this cause variation on the motor slip and fast Fourier transform problems appear due to non-stationary signal. This paper experimentally describes the effects of rotor b...

Abstract: In this paper, the control scheme of a distributed high-speed generator system with a total amount of 12 generators and nominal generator speed of 7000 min−1 is studied. Specifically, a fault tolerant control (FTC) scheme is proposed to keep the turbine in operation in the presence of up to four simultaneous generator faults. The proposed controller structure consists of two layers: T...

the zagros fold- thrust belt as a part of alpine- himalayan orogenic belt, is one of the most active continental collision zones on the earth, which extends from the tarus mountains in south eastern turkey to the minab fault in the east of the strait of hormoz in southern iran. structurally, its formation is related to the continuing convergent movement between the arabian plate to the southwes...

The loading path the fault experiences is often neglected when evaluating its potential for reactivation and related seismic risk. However, stress history affects zone compaction dilation, thus mechanics. Therefore, in incohesive cores that could dilate or compact, role of not be ruled out. Here we reproduce laboratory different tectonic paths reverse (load-strengthening absence significant flu...
