In this research study, energy, exergy and economic analyses is performed for a combined cycle power plant (CCPP) with a supplementary firing system. The purpose of this analyses is to evaluate the economic feasibility of a CCPP by applying an optimization techniques based on Evolutionary algorithms. Actually, the evolutionary algorithms of Firefly, PSO and NSGA-II are applied to minimize the c...

the purpose of this study is to assess the transaction cost of borrowing from non-governmental investment development funds which are established in less than a decade. transaction costs are considered as significant and limiting factors for micro-borrowers in using formal loans. the required data are provided by the investment developing support’s parent company using the stratified random sam...

In  this  research,  biological  removal  of  phenol  and  orthonitrophenol  (2NP)  pollutants  from wastewater  by  continuous  moving  bed  sequencing  batch  reactor  (MSBR)  was  studied.  The experiments were conducted in various operational conditions to find out the optimum level of the significant  parameters.  Best  performance  for  removal  of  Phenols  was  achieved  when  parameter...

Despite extensive information on the adverse physical and psychological consequences of malnutrition, there is little information on its economic consequences. International studies suggest that disease-related malnutrition increases hospital costs by 30-70%. In the United Kingdom the Malnutrition Universal Screening Tool (MUST) was used as the basis for identifying the prevalence of malnutriti...

BACKGROUND Fixed-dose combination of isosorbide dinitrate/hydralazine (ISDN/HYD) improved clinical outcomes in the African-American Heart Failure Trial (A-HeFT). We assessed the resource use, costs of care, and cost-effectiveness of ISDN/HYD therapy in the A-HeFT trial population. METHODS AND RESULTS We obtained resource use data from A-HeFT, assigning costs through the use of US federal sour...

  Background: It has been suggested, although not proven, that presence of concomitant psychiatric disorders may increase the inpatient costs for patients undergoing elective surgery. This study was designed to test the hypothesis that elective lumbar fusion surgery is more costly in patients with under treatment for depression. Methods: This is a retrospective case-control study of 142 patient...

  These days, data mining one of the most significant issues. One field data mining is a mixture of computer science and statistics which is considerably limited due to increase in digital data and growth of computational power of computer. One of the domains of data mining is the software cost estimation category. In this article, classifying techniques of learning algorithm of machine ...

BACKGROUND although proactive primary care, including early detection and treatment of community-dwelling frail older people, is a part of the national healthcare policy in several countries, little is known about its cost-effectiveness. OBJECTIVE to evaluate the cost-effectiveness of a proactive primary care approach in community-dwelling frail older people. DESIGN AND SETTING embedded in ...
