An NHPP Software Reliability Model with S-Shaped Growth Curve Subject to Random Operating Environments and Optimal Release Time

open access: yesApplied Sciences, 2017
The failure of a computer system because of a software failure can lead to tremendous losses to society; therefore, software reliability is a critical issue in software development.

A Non-homogeneous Count Process: Marginalizing a Poisson Driven Cox Process [PDF]

open access: yes, 2023
The paper considers a Cox process where the stochastic intensity function for the Poisson data model is itself a non-homogeneous Poisson process. We show that it is possible to obtain the marginal data process, namely a non-homogeneous count process ...

Numerical Solution Method for Software Reliability Growth Model Within Framework of Generalized Polynomial Chaos [PDF]

open access: yesJisuanji kexue yu tansuo
As the quality of software systems improves, the demand for the reliability of software systems increases. Due to the complexity of software systems and the uncertainty inherent in their operating environments, it is challenging for researchers to obtain

Insular organization of gene space in grass genomes. [PDF]

open access: yesPLoS ONE, 2013
Wheat and maize genes were hypothesized to be clustered into islands but the hypothesis was not statistically tested. The hypothesis is statistically tested here in four grass species differing in genome size, Brachypodium distachyon, Oryza sativa ...

Poisson algebras via model theory and differential-algebraic geometry [PDF]

open access: yes, 2017
Brown and Gordon asked whether the Poisson Dixmier–Moeglin equivalence holds for any complex affine Poisson algebra, that is, whether the sets of Poisson rational ideals, Poisson primitive ideals, and Poisson locally closed ideals coincide.

Reliability Analysis and Optimal Replacement Policy for Systems with Generalized Pólya Censored δ Shock Model

open access: yesMathematics, 2023
A fresh censored δ shock model is investigated. The arrival of random shocks follows a generalized Pólya process, and the failure mechanism of the system occurs based on the censored δ shock model.

Poisson Structures for PDEs Associated with Diffeomorphism Groups [PDF]

open access: yes, 2004
We study Poisson and Lie-Poisson structures on the diffeomorphism groups with a smooth metric spray in connection with dynamics of nonlinear PDEs. In particular, we provide a precise analytic sense in which the time t map for the Euler equations of an ...

Volcanic hazard assessment for the Canary Islands (Spain) using extreme value theory [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2011
The Canary Islands are an active volcanic region densely populated and visited by several millions of tourists every year. Nearly twenty eruptions have been reported through written chronicles in the last 600 yr, suggesting that the probability of a new ...

Warranty Claim Forecasting Based On Weighted Maximum Likelihood Estimation [PDF]

open access: yes, 2012
Warranty claims reported in recent months might carry more up-to-date information than those reported in earlier months. Using weighted maximum likelihood estimation for estimating model parameters might therefore lead to better performance of warranty ...
