BACKGROUND AND AIMS In the older population, the reliability of heart rate variability (HRV) has only been evaluated in a few studies, in the supine position, and covering a broad sample of age and patients of both sexes. To document the relevance of using HRV analysis in healthy older women, the aim of this study was to evaluate the reliability of HRV indexes during three classical tests. ME...

In this article the questions of the system research of reliability indexes of the infocommunication network with distributed structure are considered. As a criterion proposed use the reliability index, based on reliability state of each level of the considered network. Showed that development of methods and algorithms of system research of reliability indexes of the infocommunication network i...

In this paper the improvement of method of automated building of state space models of complex technical systems for critical application was proposed. On the basis of the developed model with the split state of critical failure the reliability and safety indexes of studied system can be obtained. Developed approach allows to estimate of reliability and safety indexes, that makes the impact of ...

Indexes of interrater reliability and agreement are reviewed and suggestions are made regarding their use in counseling psychology research. The distinction between agreement and reliability is clarified and the relationships between these indexes and the level of measurement and type of replication are discussed. Indexes of interrater reliability appropriate for use with ordinal and interval s...

The developed software ASNA-2, which is an improved version of the software ASNA-1, is based on the technology of automated estimation of reliability indexes of fault-tolerant systems. This software is designed for automated evaluation of the reliability indexes of fault-tolerant hardware – software systems. This paper describes a software ASNA-2 with the peculiarities of procedures of reliabil...

increasing overall liberalization and improving reliability indexes are the two prime but often conflicting objectives of electricity markets. proper embedding of regulatory intervention of price caps provides an effective means to tradeoff between these two objectives. surprisingly, in the context of the infinitely repeated game paradigm, as in the case of actual electricity markets, the domin...

Twenty studies examining the reliability of assessment devices and outcome measures in therapeutic research were reviewed and analyzed. The 20 investigations contained 215 quantitative reliability values published in either the American Journal of Occupational Therapy or Physical Therapy during the past 5 years. The reliability studies were classified as interrater, intrarater, test-retest, or ...

Abstract High levels of reliability and high security are the basic characteristics and requirements of railway signal systems. So, reliability, availability and maintainability (RAM) are necessarily analyzed before the computer interlocking system will be adopted. The All-electronic Computer Interlocking System, which is a new kind of interlocking system, still needs to analyze its RAM before ...
