Abstract— An important aspect of network management is fault management, i.e., determining, locating, isolating, and correcting faults in the network. We study modeling of communication network protocols, and their fault detection, fault identification and fault location in the discrete event systems diagnosis framework. Our approach provides a systematic way of performing fault diagnosis in ne...

The process of simple fault injection into Pspice simulation environment has the disadvantage of low efficiency and low degree of automation. To address this problem, a multi-fault injector is designed and implemented. It can not only be capable of the single fault injection, but also have the function of the batch injection for the same fault type. Firstly, this paper explains the fault inject...

one of the major problems that may occur in the differential protection systems of power transformers is mal-operation of the protection relays in sake of internal fault detection, because of similarity between this current and inrush current. this paper presents a novel approach for discriminating inrush current from internal fault in power transformers based on improved gravitational search a...

vehicle driveline system and its working accuracy play an important role in the performance of car. the purpose of this study is to provide an appropriate mechanism for investigating, identifying and determining the position and size of defects in the vehicle power transmission system. this is based on the patterns of the residual signal, obtained from a simulated model of the system. neuro-fuz...

fault tolerance is one of the important issues in industries, such as transportation, military, chemical and nuclear sectors. reliability and safety are two vital attributes of fault tolerant systems, and redundancy is a common way to improve these parameters. this article studies the impact of including cold standby spares in system architecture. to do this, it uses the markov model of the sys...

Batubesi Dam which is located in Sorowako region in the middle part of Sulawesi island had been designed with seismic coefficient about 0.20g. The region constitutes an active earthquake zone with the recurrence frequency and magnitude of the earthquake are relatively high. The region is located on and active fault zone due to lateral fault movement (strike-slip) of Matano fault, Palukoro fault...

Grid Computing allows coordinated and controlled resource sharing and problem solving in multi-institutional, dynamic virtual organizations. Moreover, fault tolerance and task scheduling is an important issue for large scale computational grid because of its unreliable nature of grid resources. Commonly exploited techniques to realize fault tolerance is periodic Checkpointing that periodically ...

This paper presents an analog fault simulation approach based on concurrent fault detection. By performing fault simulation with fault dropping, high computational effort is saved. The concurrent fault detection can be applied to most analyses and is compatible with other speedupprocedures. Experimental results demonstrate the effectiveness of the presented fault simulation procedure.
