In the context of the global potential energy crisis and aggravating regional environmental pollution, Chinese photovoltaic power generation still faces the key problems of sustainable development, even given its favorable background in large-scale exploitation. Scientific evaluation of the comprehensive efficiency of photovoltaic power generation is of great significance because it will improv...

A behavioral model in PSpice for a silicon carbide (SiC) power MOSFET rated at 1200V / 33A for a wide temperature range is developed by extracting the device parameters from the data sheet. The static and dynamic behavior of the SiC power MOSFET is simulated and compared with the device characteristics to validate the accuracy of the PSpice model. The temperature dependent behavior of the MOSFE...

Magnetic resonance imaging (MRI) enables 3-D imaging of anatomical structures. However, the acquisition of MR volumes with high spatial resolution leads to long scan times. To this end, we propose volumetric super-resolution forests (VSRF) to enhance MRI resolution retrospectively. Our method learns a locally linear mapping between low-resolution and high-resolution volumetric image patches by ...

The erect panicle model super-rice can rationally transform the solar energy into accumulated organic matter (biomass) and increase grain yield. The phenotype of erect panicle architecture controlled by DENSE AND ERECT PANICLE 1 (DEP1) has been used in rice breeding for nearly a century owing to its high-yield, lodging tolerance with strong stem, reasonable population structure and high nitroge...

in this survay the total productivity of export development bank of iran (edbi) and the productivity changes of branches was studied by using the method of data envelopment analysis. slacks-based measure of super-efficiency model was used to analyze the total productivity of the edbi in the period of 1373-1384 and malmquist productivity index was used to measure the growth of productivity in br...

In this work, a fast single image super resolution reconstruction (SRR) approach via image separation has been proposed. Based on the assumption that the edges, corners, and textures in the image have different mathematical models, we apply different image SRR algorithms to process them individually. Thus, our approach is divided into three steps: 1) separating the given image into cartoon and ...

Conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. In the recovery system, super-critical an CO2 is employed as the working fluid operating in a Brayton cycle. Low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes th...

Despite extensive studies on the flexibility of manufacturing systems over the last two decades, a unified measurement approach has not been developed. In this study, we propose a generic model to measure machine flexibility with consideration of the dynamic perspective of manufacturing systems. To this end we integrate two streams of machine flexibility from the literature: operational capabil...
