For mobile 3D graphics systems, even though performance requirements are met, an efficient power management is even more important for battery-powered mobile devices since they require a large number of arithmetic operations as well as a high frequency of memory accesses. According to the analysis of the power consumption of mobile 3D graphics pipelines and the slacks across the pipeline stages...

An increasing number of organizations and businesses around the world use cloud computing services to improve their performance in competitive marketplace. However, one biggest challenges using is measurement selection best service providers (CSPs) based on quality (QoS) requirements <xref ref-type="bibr" rid="ref13" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/...

Abstract China’s commercial banks have developed at a very rapid speed in recent decades. However, with global economic development slowing down, the impact of gross domestic product growth as an exogenous factor cannot be ignored. Most existing studies only consider internal factors banks, and neglect their external factors. This study thus adopts undesirable dynamic slacks-based measure under...

In this paper an approach in data envelopment analysis dealing with evaluation of non – zero slacks was propounded. This approach intends that weight of inefficient and weak efficient points that have been evaluated as zero weight, be considered as positive weight, and also in this approach, the pareto efficiency evaluates the picture of this point. In this approach positive weights in the i...

DEA is a non-parametric and linear programming based technique that attempts to maximize a decision making unit’s (DMUs) relative efficiency, expressed as a ratio of outputs to inputs, by comparing a particular unit’s efficiency with the performance of a group of similar DMUs that are delivering the same service. The traditional DEA models treat DMUs as black boxes whose internal structure is i...

In this study, we adopt a three-stage approach, DEA method, Frontier regressions, and DEA method to estimate bank efficiency based on information obtained from 29 banks in Taiwan for the period from 2002 to 2004. In the first stage, we employ super SBM (super Slacks-Based Measure) to estimate the scores relating bank efficiency including internal risk. In the second stage, a stochastic frontier...

The main motivation of this article is to illustrate dynamic network data envelopment analysis (DN-DEA) in commercial banking with emphasis on testing robustness. To this end, sixteen foreign banks in China are benchmarked against thirty-two domestic banks for the post-2007 period that follows major reforms. When network and dynamic dimensions are brought together, a more comprehensive analysis...

Tourism eco-efficiency analysis is an effective tool to solve the problem of sustainable tourism development. The evaluation index system was constructed in study, and undesirable output super-slacks-based measure model used estimate 26 cities Yangtze River Delta. Then, modified gravity based on values each city construct a spatial correlation network. structural characteristics association net...

In recent years, China’s high-tech industry has made remarkable technological progress, but it also brought serious environmental pollution, which aroused great concern about its efficiency. Although foreign technology transfer is considered as important ways for progress of the industry, existing research on what role plays in improving efficiency still lacking. Based interprovincial panel dat...
