Reliability and Availability Analysis of a Two-Unit Cold Standby System with Imperfect Switching
AxiomsThis paper presents a stochastic analysis of a two-unit cold standby system incorporating imperfect switching mechanisms. Each unit operates in one of three states: normal, partial failure, or total failure.

Quality and Reliability Engineering International, Volume 41, Issue 5, Page 1831-1847, July 2025.ABSTRACT The degradation of concrete structures is a significant issue in the United States, with the corrosion of steel reinforcement being a primary contributor. Cracks in concrete intensify the corrosion process by allowing easier access for chloride ions from deicing salts, adversely affecting the lifespan of structures.

An EM‐based likelihood inference for degradation data analysis using gamma process
Applied Stochastic Models in Business and Industry, Volume 41, Issue 3, May/June 2025.Abstract The gamma process is widely used for the lifetime estimation of highly reliable products that degrade over time. Typically, incomplete likelihood is used to estimate the model parameters and the reliability estimates for the first passage time distribution of the gamma process; however, it (i.e., pseudo method) does not consider interval ...

Reliability Evaluation for Clustered WSNs under Malware Propagation
Sensors, 2016 We consider a clustered wireless sensor network (WSN) under epidemic-malware propagation conditions and solve the problem of how to evaluate its reliability so as to ensure efficient, continuous, and dependable transmission of sensed data from sensor ...

Applied Stochastic Models in Business and Industry, Volume 41, Issue 3, May/June 2025.ABSTRACT This article presents a real‐time predictive maintenance model of vehicle suspensions based on vibration signal analysis. The study is grounded in the observation that suspension wear and failure are primarily driven by cumulative stresses and external shocks encountered during vehicle operation.

Space Weather, Volume 23, Issue 5, May 2025.Abstract The enhanced variation of the magnetic field during severe to extreme geomagnetic storms induces a large geoelectric field in the subsurface. Grounded infrastructure can be susceptible to geomagnetically induced currents (GICs) during these events.

Optimal Multi-Objective Burn-In Policy Based on Time-Transformed Wiener Degradation Process
IEEE Access, 2019 Burn-in is an effective and widely used means to improve product reliability by eliminating weak units before they are distributed in the market. Traditional burn-in that distinguishes weak units by failure during testing is inefficient and incompetent ...
