Research ArticleOpen accessEvery word in the titleEvaluation of Reliability and Availability Characteristics of Two Different Systems by Using Linear First Order Differential EquationsKhaled M. El-Said, Mohamed S. EL-SherbenyThis study deals with the reliability and availability characteristics of two different series system configurations. The second system differs from the first system due to the additional feature of preventive maintenance. The failure times of a components are assumed to be exponentially distributed with parameters α,β,α' and β', respectively. The replacement time distribution of each server is also exponentially distributed … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,659 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimation and Reliability for a Special Type of Semi-Markov ProcessVlad Stefan Barbu, Alex Karagrigoriou, Andreas MakridesThis work deals with multi-state systems modelled by means of semi-Markov processes. The sojourn times are seen to be independent not identically distributed random variables and assumed to belong to one of two different general classes of distributions so that the first class is closed under maxima and the second one is closed under minima. We obtain maximum likelihood estimators … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 20 Oct 2019 · 7,047 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleService Loyalty Measurement Scale: A Reliability AssessmentJ. Clement Sudhahar, Duraipandian Israel, A. Prabhu Britto, M. SelvamThis research article demonstrates the application of Confirmatory Factor Analysis (CFA) in the scale development process of measuring the construct Service Loyalty (SERVLOYAL). The conceptualization of SERVLOYAL is presented, the dimensions forming the SERVLOYAL construct are figured out. The nitty-gritty of CFA is discussed. And the results of CFA analysis for SERVLOYAL scale developed are found to be reliable. This … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,860 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleValidity and Reliability of an Alcohol Withdrawal Clinical Assessment Scale for Use with Acutely Ill Patients: An Abbreviated Version of the CIWA-ArPerry M. Gee, Herschel Knapp, Kevin P. Miller et al.The number of people in the United States admitted to hospitals with alcohol use disorder is increasing. Screening for alcohol dependence is a critical component to prevent alcohol withdrawal syndrome which places both the patient and staff at risk for injury. Management of symptoms includes early identification of at-risk individuals and continuous assessment of symptoms and treatment plans. In light … …International Journal of Research in Nursing, Vol. 8, Issue 2 · 6 Mar 2018 · 14,687 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReliability and Economic Analysis of a Power Generating System Comprising One Gas and One Steam Turbine with Random InspectionDalip Singh, Gulshan TanejaReliability and economic analysis for a power generating system comprising one gas and one steam turbine has been done wherein the inspection for doing one of the three types of maintenance (Minor, Path or Major) is carried out randomly. Initially, both the units i.e., the gas turbine as well as the steam turbine are operating. On failure of the gas … …Journal of Mathematics and Statistics, Vol. 10, Issue 4 · 1 Jan 2015 · 8,429 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePossibility and Evidence-Based Reliability Analysis and Design OptimizationHong-Zhong Huang, Liping He, Yu Liu et al.Engineering design under uncertainty has gained considerable attention in recent years. A great multitude of new design optimization methodologies and reliability analysis approaches are put forth with the aim of accommodating various uncertainties. Uncertainties in practical engineering applications are commonly classified into two categories, i.e., aleatory uncertainty and epistemic uncertainty. Aleatory uncertainty arises because of unpredictable variation in the performance … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 26 Mar 2013 · 7,663 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparison of the Bayesian and Other Methods for Estimation of Reliability Function for Burr-XII DistributionSafaa Ali Nasir, Nashaat Jaisam Al-AnberProblem statement: The Burr-XII distribution has been widely used especially in the modeling of life time event data. It provides a statistical model which has a wide variety of application in many areas and the main advantage is its ability in the context of life time event among other distributions. The conventional maximum likelihood method is the usual way to … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 27 Dec 2011 · 7,852 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReliability of Simple 3-Dimnesional Consecutive k-Out-of-n: F SystemsM. Gharib, E. M. El-Sayed, I.I.H. NashwanProblem statement: In this study, the reliability of some special cases of a 3-dimnesional consecutive k-out-of-n: F system and k-within consecutive (2,2,2) -out-of- (m,2,2): F system were discussed. Approach: The 3 dimensional systems is a generalization of 1 and 2 dimensional, systems. Projections from 3 dimensional systems to 2 or 1 dimension as special cases is very helpful to find … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,443 accessesView PDFCite

F. YaoA jet of fluid discharging into a cross stream, also known as Jet In Crossflow (JICF), has received many experimental and numerical investigations. In addition to the fundamental understanding of three-dimensional mixing and shear flow characteristics, the fluid dynamics research community often regarded it as a benchmark test case for validating turbulence models. Although many authors considered the canonical case … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 6,958 accessesView PDFCite
