the design and application of a fuzzy logic based controller to a leakage current relay waspresented in this paper. a novel approach based on fuzzy logic to form the tripping action of leakagecurrent relay was investigated. in addition to the theoretical aspect of fuzzy logic, detection of a leakagecurrent, measurement of the leakage current, determination of its duration, trip opening of fault...

A systematic quantitative methodology for the reliability analysis of stability of rock slopes is presented. A sliding mass resting on an inclined plane and composed of two blocks separated by a vertical tension crack is considered, and a disjoint cut-set system formulation is proposed, with each cut-set corresponding to a different failure mode of the slope. Methods for the evaluation of the s...

Software Engineering is associated with development of software products using well defined principles, techniques and processes. The result of Software Engineering is an effective and reliable product. The software products have chances to fail during implementation and design phases. The design time testing and reliability measurement can enhance the process of development and their component...

This paper undertakes a general reliability study using both classical and Bayesian semi-parametric degradation approaches. The goal is to illustrate how degradation data can be modelled and analysed to flexibly determine reliability to support preventive maintenance strategy making, based on a general data-driven framework. With the proposed classical approach, both accelerated life tests (ALT...

On-board diagnostic systems play an important role in the current generation of cars and will play an increasingly important role in the next future. The design of on-board diagnostic systems is a challenging problem under several points of view. In this paper we discuss the experience we made on such a problem within the VMBD project. In particular, we discuss an approach which tries to reconc...
