Evolutionary algorithms solve problems by simulating the evolution of a population candidate solutions. We focus on evolving permutations for ordering such as traveling salesperson problem (TSP), well assignment quadratic (QAP) and largest common subgraph (LCS). propose cycle mutation, new mutation operator whose inspiration is well-known crossover operator, concept permutation cycle. use fitne...
Sequencing batch reactor (SBR) technology has found many applications in industrial wastewater treatment in recent years. The aim of this study was to determine the optimal time for a cycle of the sequencing batch reactor (SBR) and evaluate the performance of a SBR for petrochemical wastewater treatment in that cycle time. The reactor was operated with a suspended biomass configuration under ae...
Introduction: Anxiety is one of the most common psychological problems after myocardial infarction. The purpose of the present study is to investigate the effect of simultaneous aromatherapy and Quran recitation on anxiety levels of patients with myocardial infarction hospitalized in CCU in Kashan Shahid Beheshti hospital in 2013. Methods: This clinical trial was conducted on 70 patients with m...
In this research, a high-temperature Rankin cycle (HTRC) with two-stage pumping is presented and investigated. In this cycle, two different pressures and mass flow rates in the HTRC result in two advantages. First, the possibility of direct recovery from the engine block by working fluid of water, which is a low quality waste heat source, is created in a HTRC. Secondly, by doing this, the mean ...
In this paper, the performance of an ejector cooling system and the effect of the following different working fluids such as water, ammonia, R134a, R141b, R12, R600 and R245fa are described and the effects of cycle parameters on the consumed heat and work and COP are studied. This cycle with the working fluid R141b has the least COP while the working fluid R₁₂ in comparison with the other worki...
