This paper deals with an optimization approach of a three-phases inverter associated to a bus capacitor filter and a heatsink. This approach considers multi-technology components and a power semiconductors generic modelling. The optimized choice is performed with a Genetic Algorithm (GA) with the help of components databases for the semiconductors, capacitors and heatsinks. The aim is to minimize...
Przedstawiono wyniki badań, które są następstwem wstępnych analiz i - w efekcie końcowym - mają służyć do optymalizacji procesu hartowania (doboru odpowiednich parametrów nagrzewania i chłodzenia w piecu hartowniczym - krzywa opisująca szybkość chłodzenia) w taki sposób, aby otrzymać strukturę martenzytyczną na odpowiedniej głębokości oraz jak najmniejsze odkształcenia lub odkształcenia równomierne,...
Some problems are known to have computationally demanding objective function, which could turn to be infeasible when large problems are considered. Therefore, fast approximations to the objective function are required. This paper employs portfolio of intelligent systems algorithms for optimising a metal reheat furnace scheduling problem. The proposed system has been evaluated for different techniques...
Increased concern about the environmental impact of the refrigeration technology is leading toward design solutions aimed at improving the energy efficiency of the related applications, using eco-friendly refrigerants, i.e. ozone-friendly and with the least possible global warming potential (GWP). In this respect, carbon dioxide (ASHRAE R744) is seen today as one of the most promising refrigerants...
