Abstract This paper applies a new approach to the identification of discourses, based on Multiple Correspondence Analysis (MCA), study discourse variation over time. The MCA keywords deals with major issue use identify discourses: allocation individual multiple discourses. Yet, as this demonstrates, also allows us observe in prevalence discourses texts patterns keyword co-occurrence. Metadata c...

A framework for analyzing competitive electric power systems has been developed. A model and simulation based upon the framework, as well as applications and extensions, are presented. The applications include an analysis of the potential gains from trade of a large-scale synchronous interconnection between the Electric Reliability Council of Texas (ERCOT) and the Southwest Power Pool and a stu...

– One promising technology to interface battery packs in electric and hybrid electric vehicles are multilevel converters. In the work presented here, it is shown how the switching times (angles) in a multilevel inverter can be chosen to achieve a required fundamental voltage and not generate speciÞc higher order harmonics. The method gives a complete solution to the problem in that all possible...

Electric vehicles are able to reduce local and global emissions from the transport sector and thereby could help to slow down global warming if they achieved significant market shares. As all other vehicles, they need a charging or refuelling infrastructure to be built up simultaneously to vehicle market penetration. With the current disability to store energy for long distance trips in batteri...
