background: for an effective treatment planning in brachytherapy, it is necessary to know the accurate source dosimetric information such as air kerma strength, exposure rate constant, dose rate constant and redial dose distribution. the usual method to determine these factors is thermo luminescent dosimeter (tld) dosimetry. nowadays, another more accurate method is known to be the monte carlo ...

The objective of this study is to present the test results of variable air volume (VAV) air conditioning system optimized by two objective genetic algorithm (GA). The objective functions are energy savings and thermal comfort. The optimal set points for fuzzy logic controller (FLC) are the supply air temperature (Ts), the supply duct static pressure (Ps), the chilled water temperature (Tw), and...

drying is a high energy consuming process. solar drying is one of the most popular methods for dehydration of agricultural products. in the present study, the performance of a forced convection solar dryer equipped with recycling air system and desiccant chamber was investigated. the solar dryer is comprised of solar collector, drying chamber, silica jell desiccant chamber, air ducts, fan and m...
