Reliability modelling and evaluating of wind turbine considering imperfect repair [PDF]

open access: yesScientific Reports, 2023
To model and evaluate the reliability of wind turbine (WT) under imperfect repair, an improved Log-linear Proportional Intensity Model (LPIM)-based method was proposed.

Lifespan differences in hematopoietic stem cells are due to imperfect repair and unstable mean-reversion. [PDF]

open access: yesPLoS Computational Biology, 2013
The life-long supply of blood cells depends on the long-term function of hematopoietic stem cells (HSCs). HSCs are functionally defined by their multi-potency and self-renewal capacity.

An Imperfect Repair Model with Delayed Repair under Replacement and Repair Thresholds

open access: yesMathematics, 2022
Based on the extended geometric process, a repair replacement model of a degradation system is studied, in which the delayed repair time depends on the working time after the last repair. Replacement and repair thresholds describe when the system will be

Point and Interval Estimators of Reliability Indices for Repairable Systems Using the Weibull Generalized Renewal Process

open access: yesIEEE Access, 2021
The generalized renewal process considers repair efficiency of imperfect repair in reliability assessment of repairable systems; therefore, its evaluation results are close to real repair circumstance than the ordinary renewal process or the non ...

Really Ageing Systems Undergoing a Discrete Maintenance Optimization

open access: yesMathematics, 2022
In general, a complex system is composed of different components that are usually subject to a maintenance policy. We take into account systems containing components that are under both preventive and corrective maintenance.

Default Detection Rate-Dependent Software Reliability Model with Imperfect Debugging

open access: yesApplied Sciences, 2022
From the perspective of FDR (fault detection rate), which is an indispensable component in reliability modeling, this paper proposes two kinds of reliability models under imperfect debugging.

Structures of LIG1 that engage with mutagenic mismatches inserted by polβ in base excision repair

open access: yesNature Communications, 2022
Ligase I seals two ends of DNA during DNA repair and replication. Here — solving structures of Ligase I with imperfect DNA harboring mismatches incorporated by DNA polymerase — the authors reveal how the repair proteins maintain fidelity at final ...

Reliability modelling and analysis of a multi-state element based on a dynamic Bayesian network [PDF]

open access: yesRoyal Society Open Science, 2018
This paper presents a quantitative reliability modelling and analysis method for multi-state elements based on a combination of the Markov process and a dynamic Bayesian network (DBN), taking perfect repair, imperfect repair and condition-based ...

Responsiveness of Multi-Channel IEC-61850 Substation Communication Network Reliability Performance to Changes in Repair Factors

open access: yesIEEE Access, 2021
Power distribution centres distribute power to motor control centres in industrial facilities, as well as supply power to medium voltage drives among other loads. In reliability studies, the use of the combinatorial methods to evaluate the reliability of
