Reliability analysis of the aircrafts normal braking system [PDF]

MATEC Web of Conferences, 2018
An identified component of Airbus A-330 aircraft which should be maintained properly is the normal braking system. The objectives of this study are to: (1) identify the critical component of the normal braking system; and (2) determine the optimal ...

Enhanced Corrosion Testing and Analysis for Steel Rebars in Reinforced Concrete Bridge Decks Based on Effective Pre‐Cracking

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 ...

Role of individual component failure in the performance of a 1-out-of-3 cold standby system: A Markov model approach

Open Engineering
The current work assesses the availability and reliability of repairable 1-out-of-3 cold standby systems, undergoing switching failure, by the Markov models, where a finite set of differential equations govern the repairable system.

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 ...

Stochastic Modeling and Time‐Frequency Analysis for Predictive Maintenance of Automotive Suspension Systems

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.

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 ...

Implementing an Operational Cloud‐Based Now‐ and Forecasting System for Space Weather Ground Effects in the UK

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.

UJI HIDUP DIPERCEPAT PADA DISTRIBUSI EKSPONENSIAL TERSENSOR TIPE II DENGAN TEGANGAN KONSTAN

Media Statistika, 2010
Accelerated Life Testing (ALT) is used to obtain information quickly on life distribution, failure rates and reliabilities. ALT is achieved by subjecting the test units to conditions such that the failure occur sooner. Prediction of long term reliability
