m-Consecutive-k-out-of-n: F Structures with a Single Change Point

open access: yesMathematics, 2020
In the present article, we introduce the m-consecutive-k-out-of-n:F structures with a single change point. The aforementioned system consists of n independent components, of which the first n1 units are identically distributed with common reliability p1,

On Estimation of Reliability Functions for the Extended Rayleigh Distribution under Progressive First-Failure Censoring Model

open access: yesAxioms, 2023
When conducting reliability studies, the progressive first-failure censoring (PFFC) method is useful in situations in which the units of the life testing experiment are separated into groups consisting of k units each with the intention of seeing only ...

Reliability Analysis of ZZ Distribution Under Zero Failure Data

open access: yesJournal of Harbin University of Science and Technology, 2020
It is a deviation reality that lifespan of some products is described by common distributions. However,the ZZ distribution can better describe the lifespan distribution of this type of product.

Optimal Control of Degrading Units through Threshold-Based Control Policies

open access: yesMathematics, 2022
Optimal control problems are applied to a variety of dynamical systems with a random law of motion. In this paper we show that the random degradation processes defined on a discrete set of intermediate degradation states are also suitable for formulating

Reliability Analysis of Different Configurations of Master and Back-Up Systems Used in Maritime Navigation

open access: yesJournal of Marine Science and Engineering, 2020
This paper presents a comparison of the reliability of various configurations of electronic navigation appliances, from a single system not duplicated (without back-up) to complex systems built of a master system and different numbers of reserve (back-up)

Actigraph data are reliable, with functional reliability increasing with aggregation [PDF]

open access: yesBehavior Research Methods, 2008
Motion sensor devices such as actigraphs are increasingly used in studies that seek to obtain an objective assessment of activity level. They have many advantages, and are useful additions to research in fields such as sleep assessment, drug efficacy, behavior genetics, and obesity. However, questions still remain over the reliability of data collected

Boltzmann-like Entropy in Reliability Theory

open access: yesEntropy, 2002
: We introduce the entropy function in order to study the reliability and repairability of systems. In detail we establish the explicit relationships between reliability and repairability; then we calculate the decay of a system due to its regular ...

Frameless ALOHA with Reliability-Latency Guarantees [PDF]

open access: yes, 2017
One of the novelties brought by 5G is that wireless system design has increasingly turned its focus on guaranteeing reliability and latency. This shifts the design objective of random access protocols from throughput optimization towards constraints ...
