An optimization model is proposed to give an economical evaluation on different network expansion plans when installing distributed generations (DGs) together with building new lines. The expenditure of construction and maintaining of new DGs as well as new lines, the annual power loss costs are both integrated into the objective function which is to minimize the annual cost of network expansion during...
To realize the power electronics building blocks (PEBB) structural's functional and spatial distribution partitioning, half bidge or H-Bridge converter are commonly used as the basic structure. Complicated converters for PEBB can be achieved by combinations of the basic building blocks. Single phase five level H-Bridge (5L-HB) with coupled inductor and series connected H-Bridge (5L-SCHB) are two important...
Semistructured data has become more and more prominent in the fast growing areas of web information technology. XML has been used as a standard format for semistructured data in representing and exchanging information in various applications. However, the lack of formality and verification support in the design of a good semistructured data model may hinder its development. For example, redundant...
We present a preliminary design and the results of simulation for a photo-detector module to be used in applications requiring the coverage of areas of many square meters with time resolutions less than 10 picoseconds and position resolutions of less than a millimeter for charged particles. The source of light is Cherenkov light in a radiator/window; the amplification is provided by panels of micro-pores...
Semantic Web services have been one of the most significant research areas within the semantic Web vision, and have been recognized as a promising technology that exhibits huge commercial potential. Current semantic Web service research focuses on defining models and languages for the semantic markup of all relevant aspects of services, which are accessible through a Web service interface. The Web...
Semantic Web services, one of the most significant research areas within the semantic Web vision, has attracted increasing attention from both the research community and industry. The Web service modelling ontology (WSMO) has recently been proposed as an enabling framework for the total/partial automation of the tasks (e.g., discovery, selection, composition, mediation, execution, monitoring, etc...
The design of an embedded control system starts with an investigation of properties and behaviors of the process evolving within its environment, and an analysis of the requirement for its safety performance. In early stages, system requirements are often specified as scenarios of behavior using sequence charts for different use cases. This specification must be precise, intuitive and expressive enough...
Summary form only given. Low-temperature-grown GaAs (LT-GaAs) has long been known to have a (sub)picosecond photo-excited carrier response time. In this paper we report the first direct measurement of the hole trapping time from the valence band in LT-GaAs, and distinguish it from electron trapping time from the conduction band and recombination time. These results are compared with trapping and recombination...
Dielectric breakdown of ultra thin (thickness <100 /spl Aring/) oxide is a major concern for ULSI circuit failure. Recent studies have found that the condition of the polysilicon gate can play an important role in the reliability of thin gate oxides. In this paper, the impact of gate doping concentration on the ultra-thin gate oxide reliability was investigated for oxides of thickness ranging from...
