One of the first ISO digital camera standards to address image microstructure was ISO 12233, which introduced the SFR, spatial frequency response, based on the analysis of edge features in digital images. The SFR, whether derived from edges or periodic signals, describes the capture of image detail as a function of spatial frequency. Often during camera testing, however, there is an interest in...

This paper presents methods for addressing two sources of variability in the context of microprocessors within-die process variability and dynamic thermal variability and shows the improvements in performance and energy efficiency obtained by applying them to a globally asynchronous, locally synchronous (GALS) microprocessor design. The GALS design style partitions the core into several indepen...

In the ongoing global efforts to reduce Green House Gas (GHG) emissions, a strong emphasis is placed on improving power plant efficiency. Fossil fuel-fired power plants today supply over 65% of electricity in the world, with coal-fired power plants accounting for about 40% of the total. The efficiency of power generation (amount of fuel to deliver a unit of electricity) varies significantly acr...

Jafri, Syed Ali, Raza. Ph.D., Purdue University, December 2013. Improving Multicore Resource Efficiency. Major Professors: T. N. Vijaykumar and Mithuna Thottethodi. With clock speeds stagnating for the last few years and multi-cores having replaced uniprocessors, software development must now turn towards shared memory parallel programming to continue enhancing performance. Shared memory parall...

the cross efficiency evaluation is used to performance measurement of decision making units in data envelopment analysis concept. one of the most important shortcoming of this method is existing alternative optimal solution and therefore, the efficiency scores are not unique. we are going to summarize the pervious models proposed by researchers and suggest an alternative secondary goal approach...

The purpose of the present study is to investigate the relationship between intellectual capital (human capital efficiency, customer capital efficiency, and structural capital efficiency) and economic value added of the listed companies on the Tehran Stock Exchange (TSE). The population includes 39 firms selected through systematic sampling. The data is collected from the audited financial stat...

Aggregation of corporate social performance (CSP) metrics poses a major challenge to researchers and practitioners. This study provides a critical evaluation of current aggregation approaches and proposes a new methodology based on Data Envelopment Analysis (DEA) to compute a CSP index. DEA is independent of subjective weight specifications and provides an efficiency index to benchmark the CSP ...
