Reliability Model of Consecutive $(2, k)$ -Out-of-( $2, n$ ) :F Systems With Local Load-Sharing

open access: yesIEEE Access, 2018
Most previous reliability models of consecutive k-out-of-n system assume that the components are independent or their reliabilities are equal. The system reliability can be obtained according to the configuration of k consecutive failed components ...

Status Set Sequential Pattern Mining Considering Time Windows and Periodic Analysis of Patterns

open access: yesEntropy, 2021
The traditional sequential pattern mining method is carried out considering the whole time period and often ignores the sequential patterns that only occur in local time windows, as well as possible periodicity.

Reliability of reliability coefficients in the estimation of asymmetry [PDF]

open access: yesAmerican Journal of Physical Anthropology, 1995
AbstractAlthough promising to provide insight into the interaction between genotype and environment, investigations into fluctuating asymmetry suffer from a lack of standardization in the reporting of measurement error. In the present paper we show, using both anthropometric and odonto‐metric data, that the use of the reliability coefficient calculated

Mission Reliability-Oriented Selective Maintenance Optimization for Intelligent Multistate Manufacturing Systems With Uncertain Maintenance Quality

open access: yesIEEE Access, 2019
Selective maintenance is widely used as a reliability-centered maintenance strategy due to the limited maintenance resources. However, existing selective maintenance studies only consider basic reliability, which cannot systematically describe the ...

Probabilistic Fatigue Crack Growth Analysis Under Stationary Random Loading With Spike Loads

open access: yesIEEE Access, 2018
The in-service loading condition of many engineering structures is generally composed of a stationary random loading caused by the mechanical vibration, and the spike loads due to occasional events, such as the sudden shock and accidental turbulence.

Life Cycle Prediction Model of Safety Vent Based on Two-Phase Degradation Process

open access: yesIEEE Access, 2018
The safety vent, the most important failsafe device of lithium ion batteries, is made of a highductility and a corrosion-resistant aluminum alloy. Safety vents are designed to release the gas pressure in the battery shell before a catastrophic explosion ...
