The space available to our perception is three-dimensional with full evidence. development of physics led the hypothesis extra dimensions. It believed that an important role in unification should play by Planck units mass, length and time, built on universal constants c (the speed light a vacuum), id="M2"> G gra...

OBJECTIVE Despite increased knowledge, improved options, and regulatory mandates, pain management of neonates remains inadequate, promoted by the ineffective translation of research data into clinical practice. The Neonatal Intensive Care Quality Improvement Collaborative 2002 was created to provide participating NICUs the tools necessary to translate research, related to prevention and treatme...

due to uncertain nature of wind and photovoltaic power units, the participation of this units in electricity markets is subjected to significant deviation penalties. this issue leads to despondency or even admission of these units in the competitive environment. with regard to this fact that the low deviations are available when predictions are performed in a short-term horizon and also distrib...

Background & Aims: Hospitals are the most important centers that provide health services in the country. They have to use scientific and efficient management at all levels for promoting health. Intensive care units (ICU) are one of the most sensitive parts of the hospitals; therefore, paying attention to its efficiency is of particular importance. The purpose of this paper was to estimate the t...

The measurement of cardiac troponins (cTns) has become the mainstay for the diagnosis of acute coronary syndrome (ACS), since the assessment of either cardiac troponin T (cTnT) or cardiac troponin I (cTnI) has now outperformed whatever other available biomarker, to be used alone or in combination with cTns (1). This paradigm shift has been strongly supported by recent introduction in clinical p...

We discuss how to aggregate multiple criteria evaluations belonging to qualitative, linearly ordered scales. Qualitative aggregation operations such as min or max can be refined by discrimin and leximin orderings, in agreement with the Pareto ordering of vector evaluations. Further refinements of discrimin orderings, as well as the generalization of discrimin and lexirnin to functions other tha...

the performance evaluation and efficiency measurement of software companies and compare them together as a set of knowledge-based activities due to the unknown of internal processes and stages common to these companies and ignoring these processes in performance evaluation by data envelopment analysis models and how to consider these processes and procedures for calculating efficiency of each s...
