This paper focuses on the space charge behavior in oil-paper insulation systems used in power transformers. It begins with the importance of understanding the space charge behavior in oil-paper insulation systems, followed by the introduction of the pulsed electrostatic technique (PEA). After that, the research progress on the space charge behavior of oil-paper insulation during the recent twen...

The comparison of measurements performed on a number of such modes at ee experiments with theoretical expectations has provided a wealth of information. The CDF II experiment has access to a large yield of these decays at the Tevatron collider, thanks to a dedicated trigger on secondary decay vertices . In addition, it is also sensitive to the corresponding decays of Bs mesons and beauty baryon...

This paper presents an electric drive system whose motor is connected to a battery by means of a buck DC/DC converter. This motor is further connected to an ultracapacitor by means of a boost DC/DC converter. First, operation and break processes are studied when the converters are switched off as well as when they are switched on in current limitation mode. Then, a comparative analysis of the r...

Object-oriented languages have recently become common, making register indirect jumps more important than ever. In objectoriented languages, virtual functions are heavily used because they improve programming productivity greatly. Virtual function calls usually consist of register indirect jumps, and consequently, programs written in objectoriented languages contain many register indirect jumps...

We introduce Blite, a lightweight language for web services orchestration designed around some of WS-BPEL peculiar features like partner links, process termination, message correlation, long-running business transactions and compensation handlers. Blite formal presentation helps clarifying some ambiguous aspects of the WS-BPEL specification, which have led to engines implementing different sema...

Ubiquitous computing provides services to users, according to their current situation. Interactions with such programs are as implicit as possible. We find among the applications the electronic supermarkets or the virtual guides for museums’ visitors. The majority of ubiquitous applications use a digital model of the physical world to compute the delivered services. With our approach the comput...

there is a general rule in criminal law, principal of innocence. according to this rule, who asserts must prove. if she succeeds, ,this principal is replaced by pricipal of criminality, (as this pricipal is valid as far as the contrary is not proven). so, it is clear that the validity of this pricipal is based on the circumstances and reasonable inferences from these circumstances. if the situa...

This study examined predictors of self-presentation concerns in sport. Two hundred and twenty eight competitive athletes (171 men and 117 women) completed measures of selfpresentation concerns, social physique anxiety (SPA), self-handicapping (SH), athletic identity (AI), and perfectionism. SPA and SH were consistent predictors across all but one self-presentation dimension in females. Gender d...

When indexing large text collections minimizing the indexing time and the disk storage used to create an index remains important. Indexing optimizations applied to a prototype retrieval system at NIST are discussed in this paper. These include the organization of the index, the use of virtual memory facilities to improve indexing time, an index addressing scheme to decrease index size, and the ...

The characteristics of shallow and deep convection during the Tropical Rainfall Measuring Mission/ Large-Scale Biosphere–Atmosphere Experiment in Amazonia (TRMM/LBA) and the Eastern Pacific Investigation of Climate Processes in the Coupled Ocean–Atmosphere System (EPIC) are evaluated in this study. Using high-quality radar data collected during these two tropical field experiments, the reflecti...
