Reliability evaluation of stochastically heterogeneous thick-walled pipe by long-term strength criterion

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
We have developed a method of probabilistic reliability evaluation of microheterogeneous thick-walled pipe, based on the already received solution of the stochastic creep boundary value problem.

Consecutive-k1 and k2-out-of-n: F Structures with a Single Change Point

open access: yesStats, 2023
In the present paper, we establish a new consecutive-type reliability model with a single change point. The proposed structure has two common failure criteria and consists of two different types of components.

Reliability Estimation of XLindley Constant-Stress Partially Accelerated Life Tests using Progressively Censored Samples

open access: yesMathematics, 2023
It often takes a lot of time to conduct life-testing studies on products or components. Units can be tested under more severe circumstances than usual, known as accelerated life tests, to reduce the testing period.

Boltzmann-like Entropy in Reliability Theory

open access: yesEntropy, 2002
: We introduce the entropy function in order to study the reliability and repairability of systems. In detail we establish the explicit relationships between reliability and repairability; then we calculate the decay of a system due to its regular ...

Reliability of Portable Spirometry Performed in the Korea National Health and Nutrition Examination Survey Compared to Conventional Spirometry [PDF]

open access: yesTuberculosis and Respiratory Diseases, 2021
Background The Korea National Health and Nutrition Examination Survey (KNHANES) is a well-designed survey to collect national data, which many researchers have used for their studies. In KNHANES, although portable spirometry was used, its reliability has

Computational Analysis of XLindley Parameters Using Adaptive Type-II Progressive Hybrid Censoring with Applications in Chemical Engineering

open access: yesMathematics, 2022
This work addresses the estimation issues of the XLindley distribution using an adaptive Type-II progressive hybrid censoring scheme. Maximum likelihood and Bayesian approaches are used to estimate the unknown parameter, reliability, and hazard rate ...

On Construction and Estimation of Mixture of Log-Bilal Distributions

open access: yesAxioms, 2023
Recently, the use of mixed models for analyzing real data sets with infinite domains has gained favor. However, only a specific type of mixture model using mostly maximum likelihood estimation technique has been exercised in the literature, and fitting ...

Probabilistic Reliability Assessment of Truss Construction in Matlab Software Platform

open access: yesTransactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2014
This paper deals with the use of probabilistic methods in assessing the reliability of the planar truss support structure. Classical Monte Carlo simulation technique was chosen for calculation of failure probability in structural elements and the entire ...

An Innovative Model of Reliability—The Pseudo-Entropic Model

open access: yesEntropy, 2019
There is an entire field of literature on reliability models. Building reliability models is most frequently done by starting from the failure rate (or hazard rate). Creating a reliability model starts with the specific type of product behavior over time,
