The change in system voltage and frequency with changing load creates problem in power system stability. For the sake of system stability and reliability, the reactive power compensation is essential for flexible AC transmission system (FACTS). The variation of reactive power causes impact on the generating units, lines, circuit breakers, transformers, relays and isolators. However the reactive...

This paper investigates the negative effects of electromagnetic interference (EMI) due to fast switching power devices (high dv/dt and di/dt) used in power electronic converters and industrial equipment. Mitigation techniques have been explored to reduce EMI noise effectively. Remedial measures to reduce the risk of equipment malfunction and health risk due to EMI have been explored. In this pa...

Variable speed operation is essential for large wind turbines in order to optimize the energy capture under variable wind speed conditions. Variable speed wind turbines require a power electronic interface converter to permit connection with the grid. The power electronics can be either partially-rated or fully-rated [1]. A popular interface method for large wind turbines that is based on a par...

The technological evolution of telecommunication networks in recent years has shown that the availability of transmission bandwidth has been growing at a faster pace than the STNitChing bandwidth inside network nodes [4]. This means that in the near future electronic switching will become the perfonnance bottleneck of high-capacity networks. The cost of a Switching device (be it an IP router, a...

this paper describes the development of a fuzzy decision support system (fdss) for the assessment of risk in e-commerce (ec) development. a web-based prototype fdss is suggested to assist ec project managers in identifying potential ec risk factors and the corresponding project risks. a risk analysis model for ec development using a fuzzy set approach is proposed and incorporated into the fdss....

entrepreneurship is the process of value setting by providinga unique set of sources for making effective use of opportunities;thus, caring about it seems to be a must. the present paper aims toinvestigate the effect of information technology management on managers’entrepreneurship in tabriz car-parts manufacturing industry. tothis end, four hypotheses were tested in the study. the population o...

By overcoming speed bottlenecks from electronic switching as well as optical/electronic conversions, all-optical logic gates can permit further exploitation of the nearly 40THz of bandwidth available from optical fibers. We focus on the use of optical solitons and alloptical logic gates to implement ultrafast "interchanges" or switching nodes on packet networks with speeds of 100Gbit/s or great...
