Importance Analysis of Components of a Multi-Operational-State Power System Using Fault Tree Models

open access: yesInformation, 2020
This article describes a case study using a fault tree analysis for a multi-operational-state system (system with several operational states) model with many different technical solutions for the power system of a fishing vessel.

Probability of an Intermediate (Reduced Operational) State [PDF]

open access: yesProblemy Mechatroniki, 2021
This work examines with the form of the well-known sum: p + q = 1 – which is the sum of the probabilities of opposite events, in particular: the sum of the probabilities of the operational and non-operational (failure) states of a single element (a ...

Effects of nonlinearity on determination of bolt forces for the operational state of a bolted flange connection

open access: yesInternational Journal of Applied Mechanics and Engineering, 2014
Modelling and calculations of an asymmetrical bolted flange connection at the operational stage are presented. The physical model of the joint is based on a flexible flange element that is connected with a rigid support by means of hybrid elements, which

Mathematical model of speech signal leakage channels during discrete-quantified conversion

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2020
The purpose of the article is to estimate the leakage channel of a discrete-quantized speech signal with amplitude-pulse modulation. Discrete-quantized analog-to-digital conversion of signals in the article is considered by the example of pulse-amplitude
