For the purpose of a clear discussion) this paper will introduce terms and paradigms used for fault tolerance. In this paper first the notions system, component, environment, design, structure and behaviour are presented. Then, the notions failure and fault are defined. After observing that designing a fault tolerant system is based on the use of redundaucy and fault hypotheses, the fundamental...

System reliability is an important issue in designing modern multiprocessor systems. This paper proposes a fault-tolerant, scalable, system architecture that adopts pipeline scheme. To verify the performance of proposed system, SimEvent/Stateflow tool MATLAB program was used to simulate system. The uses twelve processors (P), connected linear array, build ten-stage with two backup (BP). However...

In a distributed Electrical Power System Faults are the major problem for regular supply to the consumers. A low impedance fault in electrical power distribution system is distinguished by a non-linear and unstable varying fault current due to type of fault. In this combined approach of Wavelet and Artificial Neural Network is used for identification and classification of all types of faults in...

In this study, the application of Bayes networks and fault tree analysis in reliability estimation have been investigated. Fault tree analysis is one of the most widely used methods for estimating reliability. In recent years, a method called "Bayes Network" has been used, which is a dynamic method, and information about the probable failure of the system components will be updated according to...

The proliferation of safety-critical embedded systems has created great demands for online fault diagnosis and fault-adaptive control techniques. A number of methodologies have been proposed, but the implementation of on-line schemes that integrate the fault detection, isolation, identification, and fault accommodation or reconfiguration tasks remains challenging. We present a tool chain using ...

The purpose of this project is to extend and integrate existing results on fault diagnostics and fault management for passenger vehicles used in automated highway systems (AHS). These results have been combined to form a fault diagnostic and management system for the longitudinal control system of the automated vehicles which has a heirarchical framework that complements the established PATH co...

This with the integration of distributed generation (DG) to meshed distribution systems, the operating time of the protective system becomes a major concern in order to avoid nuisance DG tripping. This paper proposes a new tripping characteristic for directional overcurrent relays (DOCRs) that can achieve a higher possible reduction of overall relays operating time in meshed distribution networ...

Changes in the physicochemical conditions of process unit, even under control, may lead to what are generically referred to as faults. The cognition of causes is very important, because the system can be diagnosed and fault tolerated. In this article, we discuss and propose an artificial neural network that can detect the incipient and gradual faults either individually or mutually. The mai...
