Some Existence Results for Systems of Impulsive Stochastic Differential Equations

Annales 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 ...

Nonlinear model predictive control for the ALSTOM gasifier. [PDF]

, 2006
In this work a nonlinear model predictive control based on Wiener model has been developed and used to control the ALSTOM gasifier. The 0% load condition was identified as the most difficult case to control among three operating conditions.

Cylindrical Wiener Processes [PDF]

, 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.
