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

Cylindrical Wiener Processes [PDF]
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
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
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.
