In today's competitive world, many manufacturing and service firms, including banks, have been forced to use new managerial approaches, and methods for assessing organizational performance. The Data Envelopment Analysis (DEA) approach is one of these approaches, which has been used to evaluate the performance of organizations since 1978. The purpose of this research is to use the technology sup...

An original data envelopment analysis (DEA) model is to evaluate each decision-making unit (DMU) with a set of most favorable weights of performance indices to finding worst-practice DMUs. Indeed classical DEA models evaluate each DMUs compared to the most effective DMU. Since in this way the relative efficiency is calculated, therefore at least one of the DMUs are located on the efficiency fro...

In this paper, we will consider the linear advection equation in one space dimension. Numerical analysis the efficiency of the minmod scheme, MC scheme, Valeer scheme the super bee scheme, Beam warming scheme, Fromm scheme. Some numerical experiments are presented to show the efficiency of the schemes.

As regards of supper efficiency models which increased the discrimination power of the standard DEA models, still infeasibility may occure. In literature there exists some models overcome this difficulty. In this paper a new procedure has been mooted in order to remove this shortcoming in a way that both input savings and output surplus are being considered. This procedure deals with nonradial ...

performance evaluation of universities is an important issue between researchers. classic data envelopment analysis (dea) models with deterministic data have been used by many authors to measure efficiency of universities in different countries. however, dea with stochastic data are, rarely used to measure efficiency of universities. in this paper, input oriented model in stochastic data envelo...

A novel image patch based example-based super-resolution algorithm is proposed for benefitting from social image data. The proposed algorithm is designed based on matrix-value operator learning techniques where the image patches are understood as the matrices and the single-image super-resolution is treated as a problem of learning a matrix-value operator. Taking advantage of the matrix trick, ...

As deployed Grids increase from tens to thousands of nodes, peer-to-peer (P2P) techniques and protocols can be used to implement scalable services and applications. The super-peer model is a novel approach that helps the convergence of P2P models and Grid environments and can be used to deploy a P2P information service in Grids. A super-peer serves a single physical organization in a Grid, and ...

Extended use of permanent magnet synchronous motors (PMSMs) has brought the need to design that can comply with latest requirements in terms efficiency. This paper presents different configurations case a 3 kW PMSM two pole pairs, focusing on finding optimal constructive solutions ensure it falls within IE4 efficiency class. Six virtual prototypes were developed and simulated using Altair FluxM...

Spirulina microalgae are a rich source of protein and valuable biological compounds. One of the most important Spirulina microalgae pigments is phycocyanin. Phycocyanin is widely used in industries as a natural blue pigment and it’s also an effective antioxidant. In order to improve phycocyanin production as well as Spirulina growth, by autotrophic cultivation considering that autotrophic culti...
