One of the leading power companies in Denmark, Elsam Kraft A/S, has proposed a vision of the Danish energy sector (end of 2004), with a working title ’’From petrol to REtrol’’ (originally ‘‘From benzin to VEnzin’’, vedvarende = renewable, in Danish). The vision points to changes in the energy sector from being based on combined production of electricity and heat to one based on combined product...

flexible ac transmission systems (facts) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. in this paper, in order to find type, size and location of facts devices in a power system a dedicated improved particle swarm optimization (dipso) algorithm is developed for de...

Many companies in the U.S. are entering the wood pellets market due to the increasing importance of woody biomass utilization for energy purposes. Despite a 200% increase in U.S. production, it is difficult to obtain reliable information from the research community relative to the production costs, requirements, and market trends for wood pellets.

Techno-economical studies in telecommunication networks are important and quite complicated topics. One of the major challenges is to estimate the investment in new or additional network equipment to consider a new service, or to compare two technologies in the same or different frequency band. In order to carry out this kind of analysis, a nationwide network design and dimensioning study has t...

The selection of the most suitable machining process for a given machining application is not straightforward and requires consideration of a number of techno-technological and economic criteria. Therefore is often viewed as a multi-criteria decision making (MCDM). This paper is focused on multi-criteria economic analysis of various machining processes by applying recently developed MCDM method...

Under clean and green revolution programme, an urgent need has been felt to develop mitigation devices and pollution control instruments. Through this paper, discussion has been made on pollution thrust emanating in atmosphere from stacks and its control through indigenous technology and control instruments developed in India to meet the techno-economical needs of country. Main emphasis has bee...
