Modeling the Role of Testing Coverage in the Software Reliability Assessment [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2023 To assure the reliability and quality of the final product, testing is an essential and crucial part in the software development cycle. During this process, fault correction/detection activities are carried out to increase the reliability of the software.

Methods in Ecology and Evolution, Volume 14, Issue 10, Page 2639-2653, October 2023., 2023 Abstract Step selection analysis (SSA) is a common framework for understanding animal movement and resource selection using telemetry data. Such data are, however, inherently autocorrelated in space, a complication that could impact SSA‐based inference if left unaddressed.

Wind Energy, Volume 26, Issue 9, Page 879-899, September 2023., 2023 Abstract This article presents a Bayesian reliability modelling approach for wind turbines that incorporates the effect of time‐dependent variables. Namely, the technique is used to explore the effect of annual services on wind turbine failure intensity through time for turbines within a currently operational wind farm.

Imperfect repair models: Sequential goodness‐of‐fit testing based on predictive performances
Quality and Reliability Engineering International, Volume 39, Issue 2, Page 609-629, March 2023., 2023 Abstract Imperfect repair (IR) modelling has attracted a lot of attention during the last decades. To assess and predict repairable systems' reliability, analysts have to choose among a plethora of models: renewal processes, non‐homogeneous Poisson processes (NHPPs), Brown–Proschan, Kijima, ARA, ARI, Quasi‐Renewal (QR), Trend‐Renewal and so forth ...

Wind Energy, Volume 26, Issue 3, Page 310-324, March 2023., 2023 Abstract Frequent failures of power converters affect the availability of wind turbines and cause considerable maintenance costs. To enhance the reliability of power converters in wind turbines, the prevailing causes and modes of failures have to be identified.

Ordered and censored lifetime data in reliability: An illustrative review
WIREs Computational Statistics, Volume 15, Issue 2, March/April 2023., 2023 Censoring of lifetime data Abstract The present review provides a survey on basic models of ordered data and censoring mechanisms with a focus on lifetime data, failure data, and reliability applications. Throughout, illustrations of the data generation process as well as of the censoring mechanisms are used to visualize these procedures. By example we

A Counting Process Approach for Trend Assessment of Drought Condition
Hydrology, 2019 This paper discusses some methodological aspects of the historical analysis of drought, particularly the trend assessment. The Standardized Evapotranspiration Index (SPEI) is widely used as a measure of drought condition.

Prediction of Tool Remaining Useful Life Based on NHPP-WPHM
Mathematics, 2023 A tool remaining useful life prediction method based on a non-homogeneous Poisson process and Weibull proportional hazard model (WPHM) is proposed, taking into account the grinding repair of machine tools during operation.
