abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
data envelopment analysis (dea) is a technique that uses all collected observations to measure performance. this method presents no data about how to operate on dmu. the present research attempted to study a unit with all its subunits, if the unit is efficient, it means that all its subunits are efficient too and if it is an inefficient, it shows clearly that which one of the subunits makes ine...
The current technologies have made it possible to execute parallel applications across heterogeneous platforms. However, the performance models available do not provide adequate methods to calculate, compare and predict the applications performance on these platforms. In this paper, we discuss an enhanced performance evaluation model for parallel applications on heterogeneous systems. In our an...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
introduction: medical records department (mrd) is important for evaluating, planning and prioritizing health care services. the major aim of this study was to evaluate the performance of the mrds of hospitals using multi-criteria decision-making approach in the selected hospitals of isfahan city, iran. methods: this was an analytical and cross-sectional study that was conducted in spring 2008 i...
This paper is particularly directed to analysts and managers with some limited familiarity with the use of mathematical modelling as an aid to decision making. It is concerned with obtaining usable solutions to well-defined mathematical representations of real world problem situations. Heuristic procedures are defined and reasons for their importance are listed. A wide variety of heuristic meth...
With the growing concern with our environment, the practice degree of green supply chain management I attractgetting more and more attention from academic and industry. Therefore, studying green supply chain management practice is a very meaningful work. Green supply chain management performance appraisal will involve a lot of indicators, and there are usually have dependence and feedback relat...
Most studies of managed fund performance use measures that are susceptible to bias caused by common time variation in risks and risk premia. Ferson and Schadt (1996) propose a conditional performance measure that controls for the common variation. Their results suggest that incorporating lagged public information variables that have been shown to predict stock returns, such as interest rates an...
