In this paper we present a method for measuring the efficiency for any economical branch. We construct the econometric approach of production frontiers, using the DEA technique (Data envelopment analysis), based on the mathematical programming approach. We effectuate an analysis of some certain data concerning the efficiency or the inefficiency of the branches, using the Efficiency Measurement ...

The investment in small hydropower plants requires the analysis of hydrological, technical, operational, budgetary, economical and financial aspects. The analysis of each possible configuration demands the joint action of several technicians, consuming substantial time and money. During initial design of the project, simplified procedures are usually adopted which may compromise the quality of ...

Leishmaniasis is a parasitic infection that is considered worldwide one of the most important public health problem, affecting more than 12 million people with an estimated number of 2 million new cases occurring annually. Among the compounds isolated from Tabernaemontana catharinensis, coronaridine and voacangine are the indole alkaloids which have antileishmanial activity. In this work, the t...

Along with the growth of Grid infrastructures, ubiquitous service provision and consumption has received wide attention in literature and practice. Although the number of available services rises rapidly, concepts and standards for an economical efficient service allocation remain in their infancy. Most proposed mechanisms lack of an interdisciplinary analysis that accounts for economical and t...

Along with the growth of Grid infrastructures over the last years, ubiquitous service provision and consumption has received wide attention in literature and practice. Although the number of available services rises rapidly, concepts and standards for an economical efficient service allocation remain in their infancy. Most proposed mechanisms lack of an interdisciplinary analysis that accounts ...

This paper presents a region-representation scheme and comparative analysis methods based on a tesseral addressing system. The proposed scheme is described in the context of performance analysis of Page Segmentation methods, a Document Image Analysis area that is particularly sensitive to both a successful region-description scheme and efficient methods for comparative analysis. The proposed te...

the aim of this study was to test the model of the relationship between violence against women and aggressive behavior in children with mediation of maternal mental health. research design was correlation and path analysis. the study population included all of preschool children¢s mothers at the city of dezful. the sample was consisted of 250 pre-school children¢s mothers. that selected by mult...

The assessment of behavioral changes produced by prenatal or early postnatal exposure to potentially noxious agents requires both the designing of ad hoc tests and the adaptation of tests for adult animals to the characteristics of successive developmental stages. The experience in designing tests is still more limited than in the adaptation of tests, but several tests have already proven their...

Let G∞ = (C d m)∞ denote the graph whose set of vertices is {1, . . . ,m}d, where two distinct vertices are adjacent iff they are either equal or adjacent in Cm in each coordinate. Let G1 = (C d m)1 denote the graph on the same set of vertices in which two vertices are adjacent iff they are adjacent in one coordinate in Cm and equal in all others. Both graphs can be viewed as graphs of the d-di...
