Reliability

Power engineering is the oldest and most traditional of the various areas within electrical engineering, yet no other facet of modern technology is currently undergoing a more dramatic revolution in technology or business structure. Perhaps the most fundamental change taking place in the electric utility industry is the move toward a quantitative basis for the management of service reliability.

To stay in business, you must develop and maintain a Value Proposition that is compelling. Whether you are a high-volume manufacturer of commercial products or a low-volume, high-value-added producer, over the last decade Reliability has become a critical aspect of that proposition. Customers have come to expect that every product shipped will work the first time and every time. This is evidenced in the PPM, Six Sigma, and Cpk programs that we, as manufacturers, are expected to deliver.

Today, the term reliability is part of our everyday language, especially when speaking about the functionality of a product. A very reliable product is a product that fulfils its function at all times and under all operating conditions. The technical definition for reliability differs only slightly by expanding this common definition by probability: reliability is the probability that a product does not fail under given functional und environmental conditions during a defined period of time (VDI guidelines 4001).

Safety/Reliability engineering did not develop as a unified discipline, but grew out of the integration of a number of activities, previously the province of various branches of engineering. Since no human activity can enjoy zero risk, and no equipment has a zero rate of failure, there has emerged a safety technology for optimizing risk. This attempts to balance the risk of a given activity against its benefits and seeks to assess the need for further risk reduction depending upon the cost.

In railway applications, performance studies are fundamental to increase the lifetime of railway systems. One of their main goals is verifying whether their working conditions are reliable and safety. This task not only takes into account the analysis of the whole traction chain, but also requires ensuring that the railway infrastructure is properly working. Therefore, several tests for detecting any dysfunctions on their proper operation have been developed.

Certain spans of utterances in a discourse, referred to here as segments, are widely assumedto form coherent units. Further, the segmental structure of discourse has been claimed to constrain and be constrained by many phenomena. However, there is weak consensus on the nature of segments and the criteria for recognizing or generating them. We present quantitative results of a two part study using a corpus of spontaneous, narrative monologues. The first part evaluates the statistical reliability of human segmentation of our corpus, where speaker intention is the segmentation criterion. ...

Previous corpus-based evaluations of the coherence of text according to Centering did not compare the coherence of the chosen text structure with that of the possible alternatives.

The objective function can be the strain energy or the mass of the structure and subjected to the constraints of displacement or vibration frequency. The reliabilitybased optimization algorithm used in this paper is a three-step closed loop: 1) Estimating the random variables by the Reliability Index (RI) method; 2) Solving the optimization problem using Sequential Quadratic Programming (SQP) method; 3) Checking and estimating the reliability by the first-order reliability method (FORM) in which the limit state function is the limit of displacement or vibration frequency of the structure.

We are given a graph G=(V,E), terminal set K⊆V and diameter d>0. Links fail stochastically and independently with known probabilities. The diameter-constrained reliability (DCR for short) is the probability that the K-diameter is not greater than d in the subgraph induced by non-failed links.
