This paper focuses on the design of a 10 MW hybrid power plant using the technical specifications (data sheet) of an industrial solar panel. The main purpose was to find out the exact electrical properties of the solar panel specialy with conjunction to its temperature, to optimize overall output energy. We first describe the most important types of solar power plants and afterwards focus on el...

This research proposes a parametric estimation of the structural dynamic efficiency measures proposed by Silva and Oude Lansink (2009). Overall, technical and allocative efficiency measurements are derived based on a directional distance function and the duality between this function and the optimal value function. The applicability of the parametric proposal is illustrated by assessing dynamic...

pressurized irrigation is a recent development that consumes more energy for the pressure produced. in thisstudy, energy consumption, waste and efficiency were investigated at a diesel and electrical sprinklerirrigation pumping plant in some fields in hamadan province during 2007-8. nebraska performance criteria(npc) were used to compare sprinkler irrigation pumping plant performance. the resul...

The literature on the measurement of regional convergence at different spatial scales and over different time periods is extensive. This study explores the potential role of variations in European regional technical efficiency as a contributing factor in providing explanation for convergence or divergence. To control for spatial dependence among regions, the paper uses a spatial stochastic fron...

This paper has studied the trends in the total factor productivity (TFP) growth of rice in India for the period 1980-81 to 2009-10 and has decomposed the TFP growth into its constituent components, viz. change in technical progress and technical efficiency. The study has used Malmquist Productivity Index approach through data envelopment analysis to estimate the TFP. The analysis has also been ...

the different model specifications have been proposed to estimate time-varying technical efficiency in the last two decades. these models have resulted different efficiency scores based on their built-in specifications. this study investigates the temporal pattern of technical efficiency based on cornwell, sickles, and schmidt (css, 1990) as well as lee and schmidt (ls, 1993) models. in order t...

This paper considers the technical efficiency gains that have been achieved since privatisation of the British passenger railway. This is done through estimation of a stochastic efficiency frontier, with efficiency gains split between those arising through technical change and those arising out of management technical performance i.e. total factor productivity. The results suggest that most of ...
