Importance measure is an index to describe the importance of an individual component or a group of components within a reliability system. Up to now, importance measures for components in stochastic reliability systems have been investigated. And importance index for a component and a group of components in an uncertain reliability system has also been studied. In the real world, components wit...

BACKGROUND The Motricity Index was used to measure strength in upper and lower extremities after stroke. The weighted score based on the ordinal 6 point scale of Medical Research Council was used to measure maximal isometric muscle strength. There is dearth of articles dealing with the reliability of this method. Therefore, the aim of this study was to determine the test retest reliability of M...

Bulk electric system reliability analysis is an important activity in both vertically integrated and unbundled electric power utilities. Competition and uncertainty in the new deregulated electric utility industry are serious concerns. New planning criteria with broader engineering consideration of transmission access and consistent risk assessment must be explicitly addressed. Modern developme...

objective: having a good quality of life has always been desirable for humans, and the concept of a good life and the ways of achieving it have become important over the years. personal wellbeing is the mental component of quality of life. thus, the current study was conducted to assess the reliability and validity of the ‘‘personal well-being index- cognitive disability’’ on mentally retarded ...

background: according to the measurements literature reliability of the test refers to the consistency of the test results and shows whether the obtained score is stable indication of the student’s performance in particular test reliability can be measured by different statistics formula. purpose: to determine the factors influenced the reliability of 392 mcq examinations. methods: the correlat...

dear editor multiple choice tests are the most common objective tests in medical education which are used to assess the ind­ividual knowledge, recall, recognition and problem solving abilities. one of the testing components is the post-test analysis. this component includes; first, qualitative analysis of the taxonomy of questions based on the bloom’s educational objectives and percentage of th...

The objective of this study was to identify measures appropriate to estimate travel time reliability and apply them to study the reliability of travel time under varying freeway operating conditions. More specifically, a case study was undertaken to study travel time reliability along the I-65 corridor in the State of Alabama. The objectives of this study were to: a) Calculate reliability metri...
