در این پژوهش به منظور برآورد تابش خالص برای مکان یابی نیروگاه های خورشیدی با پردازش تصاویر ماهواره ای در استان کردستان از دو روش sebal و روش solar analysis استفاده شده است در روش sebal از داده های تصاویر ماهواره ای مودیس 2000، 2003، 2006، 2009، 2012 داده های ساعات آفتابی در7 ایستگاه سینوپتیک در سطح استان کردستان ( داده های روزانه) و برای روش solar analysis از تصاویر دم منطقه با قدرت 30 و 90 متر...
welders exposure to nickel and hexavalent chromium in welding fumes is associated with increase of cancer risk in welders. in this study we calculated cancer risk due to exposure to these compounds in welders.the role of exposure parameters in welders on derived incremental lifetime cancer risk were determined by stochastic modeling of cancer risk. input parameters were determined by field inve...
financial companies are constantly exposed to the dangers of risk. in the last few years for various reasons, measuring value at risk (var) has become increasingly important for financial firms. the study of multiple measures of risk, var measure with a new approach provides the ground for calculation of market risk. common approaches to risk measurement due to complicated, nonlinear and changi...
introduction: the greatest part of constructed dams belongs to embankment dams and there are many examples of their failures throughout history. about one-third of the world’s dam failures have been caused by flood overtopping, which indicates that flood overtopping is an important factor affecting reservoir projects’ safety. moreover, because of a poor understanding of the randomness of floods...
this study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. however due to unpredictable nature...
