Power systems become large and complex, so the occurrence rates of a great deal of energy loss caused by faults become high. In this situation, the development of the efficient search method for high risk events of power systems is strongly required. Risk is defined as the product of energy loss and its occurrence rate, considering that the goal of power systems is the stable supply of power. T...

For several years, European financial markets have been the place of important mutations. These mutations have hit both stock markets themselves as well as the infrastructures including all necessary services for the transactions on financial securities. Among the market services to which the investors appeal, is the clearing of the orders, the service which allows reducing exchanged flows whil...

risk assessment of soil erosion, one of the most important land degradation problems worldwide, is very essential for land and water resources management, and development of soil conservation methods. in the present study, the temporal changes of soil erosion risk were assessed from 1987 to 2010, based on the revised universal soil loss equation (rusle) using remote sensing (rs) and geographic ...

objective: contradictory results have been reported over microleakage studies of restorative materials and methods. despite the number of publications on leakage there are few evidences comparing the different microleakage evaluation methods. the purpose of the present study was to compare the clearing technique and longitudinal sectioning in the evaluation of dye penetration along a glass fibe...

The purpose of the paper is to analyze the transient stability of an industrial cogeneration system in Hsin-Chu Science-Based Industrial Park using ETAP software. The cogeneration system is installed two 161kV/161kV high-impendence transformers with tap-changer to connect with TPC for decreasing the short-circuit fault current and increasing the fault critical clearing time. The transient stabi...

Wind energy conversion systems are very different in nature from conventional generators. Therefore dynamic studies must be addressed in order to integrate wind power into the power system. Angular stability assessment of wind power generator is one of main issues in power system security and operation. The angular stability for the wind power generator is determined by its corresponding Critic...

Critical Path Profiling is a technique that provides guidance to help programmers try to improve the running time of their program. However, Critical Path Profiling provides only an upper bound estimate of the improvement possible in a parallel program execution. In this paper, we present a new metric, called Slack , to complement Critical Path and provide additional information to parallel pro...

We study three generic clearing arrangements in the presence of two-sided limited commitment: simple bilateral clearing, segregated collateral through a third party, and—most sophisticated—central counterparty (CCP) clearing. Clearing secures settlement obligations from over-the-counter forward contracts that smooth income risk-averse traders. requires to guarantee settlement; this is costly, a...
