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...
When dealing with research and development of gun propellants, a less expensive, quicker and safer process of closed vessel evaluation adopted rather than gun firing. In the current research work a computer program (BRCBADR) has been developed for the burning rate reduction from closed vessel test data. Correct determination of thermo-chemical properties of propellants provides accurate results...
Hierarchical analysis is one of the prioritization methods of phenomena. This method provides comparison and use of expert people. In this research, the men-tioned method was applied in order to weight and prioritize valuation factors and indicators for applied science in primary school. The methodology of this research is descriptive survey. The statistical population is all experts (education...
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...
Suitable stable channel design and optimization of river geometry can reduce cost of projects. The regime theory provides the possibility of empirical and semi-empirical investigations of stable channel design in which erosion and sediment transport are in equilibrium. The objective of this research is an investigation and a comparison of the influence of uniform and non-uniform flows on the pr...
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 ...
