Divisible rough sets based on self-organizing maps
(Sin editorial (Calcuta, India), 2005-12-20)The rough sets theory has proved to be useful in knowledge discovery from databases, decision-making contexts and pattern recognition. However this technique has some difficulties with complex data due to its lack of ... -
Coupled electromechanical cost optimization of high speed railway overheads
(Sin editorial (Atlanta, Estados Unidos de América), 2006-05-22)This paper presents a coupled electromechanical optimization of the cost of high speed railway overheads. The proposed electromechanical optimization solves the coupled mechanical and electrical problems by obtaining the ... -
Critically-congested Nash-Cournot equilibria in electricity networks
(Sin editorial (Estocolmo, Suecia), 2007-05-21)Oligopolistic generators behaviour may result in equilibria characterized by critically-congested lines, that is, congested lines such that arbitrarially small generation changes cause them to be not-congested. The nature ... -
Catenary and autotransformer coupled optimization for 2x25kV systems planning
(Sin editorial (Praga, República Checa), 2006-06-22)In the design process of a 2x25kV power supply, the location and sizing of autotransformers and the choice of the catenary type are usually two aspects very closely interrelated. As a result, the number of autotransformers ... -
A mixed ACDC model for railways’ power systems
(Sin editorial (Praga, República Checa), 2006-06-22)A method to study railways’ power supply systems with AC power distribution networks and DC power feeding is presented in this paper. The aim of this work is to obtain a DC model of the whole system in which AC networks ... -
