On Hahn-Banach theorem and some of its applications

open access: yesOpen Mathematics, 2022
First, this work provides an overview of some of the Hahn-Banach type theorems. Of note, some of these extension results for linear operators found recent applications to isotonicity of convex operators on a convex cone.

Wind power time series simulation model based on typical daily output processes and Markov algorithm

open access: yesGlobal Energy Interconnection, 2022
The simulation of wind power time series is a key process in renewable power allocation planning, operation mode calculation, and safety assessment. Traditional single-point modeling methods discretely generate wind power at each moment; however, they ...

Markov Moment Problems on Special Closed Subsets of Rn

open access: yesSymmetry, 2022
First, this paper provides characterizing the existence and uniqueness of the linear operator solution T for large classes of full Markov moment problems on closed subsets F of Rn. One uses approximation by special nonnegative polynomials. The case when F is compact is studied. Then the cases when F=Rn and F=R+n are under attention.

Markov decision programming–the moment optimal problem for the first-passage model [PDF]

open access: yesThe Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1997
AbstractIn this paper, we discuss MDP-the moment optimal problem for the first-passage model. A policy improvement iteration algorithm is given for finding the k-moment optimal stationary policy.

Performance characteristics of the fork-join queuing system

open access: yesInformatika, 2023
Objectives. The problem of investigating a fork-join queuing system is considered. It is required to build the process of the system functioning, to find the condition for the existence of a stationary distribution, and propose algorithms for calculating
