The paper describes winding failures in Permanent Magnet Synchronous Motor (PMSM) which are preferred Electric Vehicles. Drive can be designed with fault tolerance to continue operate under occurrence of faults. Winding insulation failure is responsible for some the most serious A method detecting open circuit winding, short or turn may result as a presented. Further technique continued post-fa...

Until about 1930, analysis of wave loads on vertical breakwaters was based trial and error. Russell(1) noted it unfortunate that “the young engineer …should be left to guided entirely by circumstances, without the aid any one general principle.” Stevenson(2) has always a difficulty in estimating force waves with which he contend.” Wave formulae Sainflou(3) Goda(4) improved design methods, but w...

This paper deals with the Reliability analysis of K-out-of-n : G redundant system in the presence of Lethal & Non-lethal Common Cause Shock failures (CCS) along with imperfect fault coverage. S.Akhtar (1994) has discussed the reliability analysis of k-out-of-n: G redundant system with Perfect and imperfect fault coverage and derived Reliability measures namely Rs (t), As (t), MTTF, MTBF. K.Mall...

greater levels of complexity in tunnelling with tunnel boring machine (tbm) allow higher chances of failures that may increase the potential hazardous risks. this paper presents the results of a study on tbm reliability using risk analysis. machinery failure mode and effect analysis was applied to analyze the risks of a tbm using qs9000 and sae.j1739 recommendations. for this purpose, 48 failur...

Un-availability can be quantitatively defined as the ratio of MTTR (mean time to repair) to the sum of MTTR (mean time to repair) and MTTF (mean time to failure). Decreasing MTTR is as valuable as increasing MTTF. By learning why systems fail, failure distribution across parts of an IS, we attempt to envision a plausible model for future Information Technology (IT). In this endeavor, we focus o...

Subjective and Objective video quality evaluation are important problems in video processing. This work describes some new guidelines for easy and reliable determination of quality metrics that are subjectively meaningful. ‘Mean Time Between Failures’ (MTBF) and ‘Probability of Failure’ (PFAIL) are introduced as new subjective quality metrics based on failure statistics, where failure refers to...

this research presents a dynamic mathematical system for modeling and simulating the quality management process in construction projects. through sets of cause and effect feedback loops, all factors that internally and externally affect the quality management process are addressed. the proposed system integrates fuzzy logic with system dynamics simulation scheme to consider the uncertainties as...
