the main objectives of this paper are measuring the technical efficiency of iranian thermal power plants and investigating the determinants of technical efficiency levels in these plants. stochastic nonparametric envelopment data (stoned) method applied to plant-level data over a period of thirteen years from 1999 to 2011. this is the first comprehensive analysis (to our knowledge) of technical...
In this paper, a multi-objective optimization method is implemented by using of genetic algorithm techniques in order to determine optimum configuration of solar chimney power plant. The objective function which is simultaneously considered in the analysis is output power of the plant. Output power of the system is maximized. Design parameters of the considered plant include collector radius (R...
in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum ra...
the graphical technique for nonlinear circuits was described that enable us to optimize circuits to obtain maximum output power, maximum efficiency or minimum intermodulation. according to this method a high power amplifier in the ka band was designed. using a nonlinear model of the transistor, optimum slope for load-line was determined so that maximum power at the output was obtainable, then ...
nasir khosrow embarks upon a seven year journey in order to come to terms with his spiritual crisis. the quest was the inevitable outcome of the tensions and conflicts between nasir and the institutionalized forms of power and knowledge. the tensions lead to the formation of a series of binary oppositions—verbal and nonverbal—within the text of his travelogue. the researchers have analyzed the ...

background and purpose: due to the lack of accurate statistics on the amount of waste generated in the energy production sector in zahedan, before any planning, one should identify all waste producing centers associated with the energy sector and also the quantity and quality of their waste in zahedan. materials and methods: this research is a cross-sectional descriptive study. it examined the ...
a number of individuals and organizations have considerable influence over the selection of global health priorities and strategies. for some that influence derives from control over financial resources. for others it comes from expertise and claims to moral authority—what can be termed, respectively, epistemic and normative power. in contrast to financial power, we commonly take for granted th...
this article agrees with recent arguments suggesting that normative and epistemic power is rife within global health policy and provides further examples of such. however, in doing so, it is argued that it is equally important to recognize that global health is, and always will be, deeply political and that some form of power is not only necessary for the system to advance, but also to try and ...
