Residual Lifetime Of System With Cold Standby Unit
(2017)In this paper, we define and study two different residual life random variables corresponding to single unit system equipped with cold standby unit. We obtain the conditional survival functions when the lifetimes Of active ... 
Complex Factorization By Chebysev Polynomials
(Univ Studi Catania, Dipt Matematica, 2018)Let {a(i)}, {b(i)} be real numbers for 0 <= i <= r  1, and define a rperiodic sequence {v(n)} with initial conditions v(0) , v(1) and recurrences v(n) = a(t)v(n1) vertical bar b(t)v(n)(2) where n t (mod r) (n >= 2). ... 
System reliability under deltashock model
(Taylor & Francis Inc, 2018)deltashock model is one of the widely studied shock models in reliability. Under this model, the system fails when the time between two consecutive shocks falls below a fixed threshold . In this paper, the survival function ... 
The eigenvalues of rperiodic tridiagonal matrices by factorization of some recursive sequences
(Elsevier Science Bv, 2018)We introduce rperiodic tridiagonal matrices for given integer r >= 2. In which the entries on the principle diagonal can be any rperiodic sequence. If the entries on the principle diagonal are equal then the calculation ... 
A new wrapped exponential distribution
(Springer Heidelberg, 2018)We introduce a new wrapped exponential distribution named transmuted wrapped exponential (TWE) distribution, for the modeling of circular datasets by using the Transmutation RankMap method. This method is employed for the ... 
The Earthquake Risk Analysis Based On Copula Models For Turkey
(Yildiz Technical Univ, 2017)This study aims to explore the dependence structure between magnitude and frequency for Turkey earthquake data. In the literature, the Gutenberg Richter (GR) model based on lineer regression is often used to determine this ... 
The Statistical Analysis of the Earthquake Hazard for Turkey by Generalized Linear Models
(Gazi Univ, 2017)In this paper, 4863 earthquake data of magnitude 4.0 and greater from 1900 to 2014 are statistically analyzed for the earthquake hazard in Turkey. The magnitudefrequency relationship in earthquake risk analysis is often ... 
Reliability and Validity of a New Test of Agility and Skill for Female Amateur Soccer Players
(De Gruyter Open Ltd, 2017)The aim of this study was to evaluate the Agility and Skill Test, which had been recently developed to assess agility and skill in female athletes. Following a 10 min warmup, two trials to test the reliability and validity ... 
The flexible skew Laplace distribution
(Taylor & Francis Inc, 2016)Skewsymmetric distributions have been discussed by several researchers. In this article we construct a skewsymmetric Laplace distribution, which is the generalization of distribution given by Ali etal. (2009) and Nekoukhou ... 
Generalizing the survival signature to unrepairable homogeneous multistate systems
(Wiley, 2016)The notion of signature has been widely applied for the reliability evaluation of technical systems that consist of binary components. Multistate system modeling is also widely used for representing real life engineering ... 
Modeling Dependent Financial Assets By Dynamic Copula And Portfolio Optimization Based On Cvar
(Ankara Univ, Fac Sci, 2015)This paper is concerned with the statistical modeling of the dependence structure of multivariate financial data using copula. Since financial data is greatly affected by the economic factors, it often varies according to ... 
Some results on the extreme distributions of surplus process with nonhomogeneous claim occurrences
(Hacettepe Univ, Fac Sci, 2015)In this paper; survival (nonruin) probability after a definite time period of an insurance company is studied in a discrete time model based on nonhomogenous claim occurrences. Furthermore, distributions of the minimum ... 
Portfolio Optimization Of Dynamic Copula Models For Dependent Financial Data Using Change Point Approach
(2016)In this paper, the portfolio optimization based on CV aR is performed using the dynamic copula model for ...nancial data. Determining thebest model of dependency between ...nancial data has an important role intaking ... 
Survival Probabilities For Compound Binomial Risk Model With Discrete PhaseType Claims
(2016)Due to having useful properties in approximating to the otherdistributions and mathematically tractable, phase type distributions are commonly used in actuarial risk theory. Claim occurrence time and individualclaim size ...
