In this study exergy and exergoeconomic analyses of a refrigeration system with two evaporators and an internal heat exchanger were performed. The analysis of the whole system included various thermodynamics parameters such as sustainability index, exergetic improvement potential, ratio of the thermodynamic losses(energetic and exergetic losses) to the capital cost, relative irreversibility for...

Due to the lack of natural water resources and high consumption in industries, desalination systems are good options supply demands, especially regions with a crisis. If these wastes used thermal cycles, addition improving efficiency reducing energy consumption, production environmental pollutants can also be reduced. In this paper, multi-stage flash brine recirculation (MSF-BR) system Abadan r...

Introduction: to identify the pattern-reversal visual evoked potential (PRVEP) waveform descriptor by evaluating discrete wavelet transform (DWT) in order to optimize stimulus in the diagnosis of anisometropia amblyopia. Materials and Methods: The PRVEP testing was performedfor 31 normal individuals and 35 patients with amblyopia. The stimuli were consisted of spatial frequencies of 1, 2, and 4...
