A Novel Model-Based Dynamic Analysis Method for State Correlation With IMA Fault Recovery

open access: yesIEEE Access, 2018
Integrated modular avionics (IMA) systems present many advantages. However, the resource sharing mechanism also brings a series of system problems, including the frequency of fault propagation and the difficulties of system design verification.

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 ...

Belief Reliability Distribution Based on Maximum Entropy Principle

open access: yesIEEE Access, 2018
Belief reliability is a new reliability metric based on the uncertainty theory, which aims to measure system performance incorporating the influences from design margin, aleatory uncertainty, and epistemic uncertainty.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Domination Reliability [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
In this paper, we propose a new network reliability measure for some particular kind of service networks, which we refer to as domination reliability. We relate this new reliability measure to the domination polynomial of a graph and the coverage probability of a hypergraph.
