Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. Also, because of power market and generators’ forced outages stochastic behavior, Monte Carlo Simulation is used for reliability evaluation. Generation r...

[Purpose] Postural problems of adolescents needs to be evaluated accurately because they may lead to greater problems in the musculoskeletal system as they develop. Although photographic posture analysis has been frequently used, more simple and accessible methods are still needed. The purpose of this study was to investigate the inter- and intra-rater reliability of photographic posture analys...

OBJECTIVE The aim of this study was to evaluate the intra and inter-rater reliability of pelvic floor muscle (PFM) dynamometric measurements for maximum and average strengths, as well as endurance. METHOD A convenience sample of 18 nulliparous women, without any urogynecological complaints, aged between 19 and 31 (mean age of 25.4 ± 3.9) participated in this study. They were evaluated using a...

The heuristic evaluation (HE) method is one of the most common in the suite of tools for usability evaluations because it is a fast, inexpensive and resource-efficient process in relation to the many usability issues it generates. The method emphasizes completely independent initial expert evaluations. Inter-rater reliability and agreement coefficients are not calculated. The variability across...

This paper aims at providing a methodology for analyzing the reliability of human evaluation in MT. In the scope of the second TC-STAR evaluation campaign, during which a human evaluation on English-to-Spanish was carried out, we first demonstrate the reliability of the evaluation. Then, we define several methods to detect judges who could bias the evaluation with judgments which are too strict...

This paper describes a new methodology based on peak load consideration for reliability evaluation of a generation system. The methodology has been developed using Simpson’s (1/3) rule for loss of load probability (LOLP) evaluation. Load models are considered as straight line and stepped load duration curve for reliability evaluation. The LOLP evaluation is based on peak load consideration. The...

Fast and accurate reliability estimation of integrated circuits is an open problem. Introducing the emerging nano devices such as FinFET and Stacked Silicon nanowires makes this problem even more challenging because of higher lithography fluctuation. We discuss several previous efforts for reliable circuit design and propose a methodology for accurate reliability estimation of novel transistors.

The series system means that both components must work for systems success. From probability concepts (independent events), the reliability (system success) of the above system (RAB) is given as: RAB = RA RB and the system unreliability (system failure), designated as Q is given as: QAB = 1 RAB = 1 RA RB considering that, Q + R = 1 or R = 1 Q, therefore, QAB = 1 (1 QA) (1 QB) = QA + QB QA QB Fo...

One of the most important factors that causes the failure of a knee prosthesis is the infection that can arise in the tissues after implantation due to an incorrect surgical procedure, to a difficult repairing process or to other patient’s pathological conditions. The infection can arise soon after implantation as well as in one or two years after the operation. In order to let the infection he...

The purpose of this article is to introduce the so-called Reliability based Customer Satisfaction Evaluation Method that is founded upon the evaluator functions using the approach of logistic-type evaluation. The scorecard based customer satisfaction measurement methods, which are widely used at Electronics Manufacturing Services (EMS) provider companies, were studied to draw conclusions on the...
