the concept of fault, like other social phenomena, is always changing, following the variable justice. the economic, moral, and philosophical consideration, are the most influential factors in the process of change. however, it seems that, apart from exceptional issues of revolutionary changes, the economic and material factors lead the way. in this historical process, the definitions of fault ...

Characteristics of ground motions close to the earthquake source can be considerably different from those of far-field motions which should be considered in design process of structures. The current study aimed to present new design response spectra for Iranian seismic design code taking into account the near-fault effects. For this purpose, a new attenuation relation based on the ground motion...

Computation of distance to fault on a transmission line is affected by: assumptions in modelling, factors reflecting system operating conditions, and measurement system characteristics. All these factors are subject to many sources of uncertainty including parameter setting errors, measurement errors, as well as absence of information and incomplete modelling of a system under fault conditions....

A study of fatal traffic crashes in Florida examined contributing factors among crashes in which younger (under age 25) drivers were found to be at fault. A case-based analysis was used to improve the accuracy and completeness of the data from the original crash reports. Results were presented using over-representation factors (ORB), a simplified but statistically significant approach to freque...

in this paper, the fuzzy system has been used for fault detection and diagnosis of a yeast fermentation bioreactor based on measurements corrupted by noise. in one case, parameters of membership functions are selected in a conventional manner. in another case, using certainty factors between normal and faulty conditions the optimal values of these parameters have been obtained through the genet...

The paper analyzes the various factors that cause failure of refrigerator evaporator. The refrigerator evaporator failure spectrum is constructed through qualitative analysis of the fault tree system after building a corresponding fault tree system. There is an analysis procedure of fault tree system based on computer aided fault tree analysis system (CAFTA).

Predicting fault proneness of classes in object oriented systems (OOS) is one of the fault management activities and may be considered as one of the cost effective ways to deal with faults. Prediction of faults needs identification and measurement of various factors that affects fault proneness of classes in OOS. In this paper, several design oriented factors have been identified that help in c...

Full chip statistical fault injection has been performed on a hardware emulated POWER6 platform. These results were validated against proton beam injection results. The fault isolation, error recovery and error logging capabilities of the POWER6 enabled measurement of the architectural derating factors. The proportion of errors as well as derating factors matched well between the simulated and ...

This paper introduces a factoring method for Dynamic Bayesian Networks (DBNs) based on Possible Conflicts (PCs), which aim to reduce the computational burden of Particle Filter inference. Assuming single fault hypothesis and known fault modes, the method allows performing consistency based fault detection, isolation and identification of continuous dynamic systems, with the unifying formalism o...
