In this paper a model for the performance prediction and optimization of air coolers for indirect refrigeration systems is presented. The model applies for finned rube air coolers operating under frosting conditions and considers the transient heat and mass transfer between humid air and air cooler surfaces. The model is extended with an energy consumption analysis for the compression refrigera...

Optimizing an indoor flow pattern according to specific design goals requires systematic evaluation and prediction of the influences of critical flow control conditions such as flow inlet temperature and velocity. In order to identify the best flow control conditions, conventional approach simulates a large number of flow scenarios with different boundary conditions. This paper proposes a metho...

the vast use of linear prediction coefficients (lpc) in speech processing systems has intensified the importance of their accurate computation. this paper is concerned with computing lpc coefficients using evolutionary algorithms: genetic algorithm (ga), particle swarm optimization (pso), dif-ferential evolution (de) and particle swarm optimization with differentially perturbed velocity (pso-dv...

background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...
