Research on two dimensional Wiener stochastic degradation model based on the wear model

open access: yesMATEC Web of Conferences, 2018
One dimensional Wiener degradation process is often used to describe the degradation of product performance. However one dimensional Wiener degradation process doesn’t sufficiently consider the relevance of multiple degradation factors and wear process ...

Some Existence Results for Systems of Impulsive Stochastic Differential Equations

open access: yesAnnales Mathematicae Silesianae, 2021
In this paper we study a class of impulsive systems of stochastic differential equations with infinite Brownian motions. Sufficient conditions for the existence and uniqueness of solutions are established by mean of some fixed point theorems in vector ...

Prediction of remaining useful life time of aero engine based on the Wiener process of three-source uncertainty

open access: yesXi'an Gongcheng Daxue xuebao, 2021
Given the problem of three-sources uncertainty in aero engine degradation process and the assumption of normal distribution of measurement error in existing research, a Wiener process aero engine residual useful life time(RUL) prediction method with ...

Cylindrical Wiener Processes [PDF]

open access: yes, 2010
In this work cylindrical Wiener processes on Banach spaces are defined by means of cylindrical stochastic processes, which are a well considered mathematical object. This approach allows a definition which is a simple straightforward extension of the real-valued situation.

RUL Prediction of Railway PCCS Based on Wiener Process Model with Unequal Interval Wear Data

open access: yesApplied Sciences, 2020
The railway pantograph carbon contact strip (PCCS) plays a critical role in collecting the electric current from the catenary to guarantee the steady power supply for the train. The catenary contacts with the PCCS and slides from one side to another side

Stochastic Equations and Equations for Probabilistic Characteristics of Processes with Damped Jumps

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
Processes such as shot noise are an adequate tool for modeling discontinuous random processes with a damping effect. Such processes arise in various fields of physics, technology and human activity, including the field of finance.

A Unified Approach for the Identification of Wiener, Hammerstein, and Wiener–Hammerstein Models by Using WH-EA and Multistep Signals

open access: yesComplexity, 2020
Wiener, Hammerstein, and Wiener–Hammerstein structures are useful for modelling dynamic systems that exhibit a static type nonlinearity. Many methods to identify these systems can be found in the literature; however, choosing a method requires prior ...
