The current reliability criterion (RC) of the film capacitor (FC) is usually a fixed value, which does not consider staged capacitance loss caused by moisture diffusion under high temperature and/or humidity. expected lifetime capacitors would deviate far from actual one. process encapsulated FC analysed based on Fick's second law. In order to investigate and characteristics, 4 types are stress...

The utilization of the wind to generate electrical energy is increasing rapidly throughout the world. By the end of 2009, the worldwide installed wind capacity reached 159,213 MW (World Wind Energy Report 2009). Wind turbine generators can be added and are being added in large grid connected electric power systems. Wind power, however, behaves quite differently than conventional electric power ...

OBJECTIVES To evaluate the test-retest reliability, the concurrent criterion validity, and the construct validity of prehospital, emergency medical service (EMS) case finding for depression and cognitive impairment in older adults. DESIGN Cross-sectional study. SETTING Prehospital EMS system and hospital emergency department. PARTICIPANTS EMS providers and community-dwelling older adult (...

Utilization of energy storage system (ESS) in microgrids has turned to be necessary in recent years and now with the improvement of storage technologies, system operators are looking for an exact modeling and calculation for optimal sizing of ESS. In the proposed paper, optimal size of ESS is determined in a microgrid considering demand response program (DRP) and reliability criterion. Both lar...

In this work we study one of the possible approaches to the optimization of the distribution of reserving files at the nodes of a network based on the reliability criterion. To estimate reliability we use an approach related to the notion of a “reliability order” parameter.

This paper presents basic decision theory rationale for selecting a particular failure probability value from its uncertainty distribution to compare to a defined acceptability criterion. Since the success probability, or reliability, is one minus the failure probability, the rationale also applies to selecting a particular reliability value to compare to a reliability criterion. The uncertaint...

BACKGROUND Foot disease complications, such as foot ulcers and infection, contribute to considerable morbidity and mortality. These complications are typically precipitated by "high-risk factors", such as peripheral neuropathy and peripheral arterial disease. High-risk factors are more prevalent in specific "at risk" populations such as diabetes, kidney disease and cardiovascular disease. To th...
