Convexity, Markov Operators, Approximation, and Related Optimization

open access: yesMathematics, 2022
The present review paper provides recent results on convexity and its applications to the constrained extension of linear operators, motivated by the existence of subgradients of continuous convex operators, the Markov moment problem and related Markov ...

New Results on Markov Moment Problem [PDF]

open access: yesInternational Journal of Analysis, 2013
The present work deals with the existence of the solutions of some Markov moment problems. Necessary conditions, as well as necessary and sufficient conditions, are discussed. One recalls the background containing applications of extension results of linear operators with two constraints to the moment problem and approximation by polynomials on ...

Event‐triggered second‐moment stabilisation under action‐dependent Markov packet drops

open access: yesIET Control Theory & Applications, 2021
This paper considers the problem of the second‐moment stabilisation of a scalar linear plant with process noise. It is assumed that the sensor communicates with the controller over an unreliable channel, whose state evolves according to a Markov chain ...

Existence, Uniqueness, and a Constructive Solution Algorithm for a Class of Finite Markov Moment Problems [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2008
We consider a class of finite Markov moment problems with arbitrary number of positive and negative branches. We show criteria for the existence and uniqueness of solutions, and we characterize in detail the non-unique solution families. Moreover, we present a constructive algorithm to solve the moment problems numerically and prove that the algorithm ...

Kinematic Modelling Without Singularity and Nonlinear Control of Satellite Attitude Using Direct Adaptive and Fuzzy PD Control Methods [PDF]

open access: yesفصلنامه علوم و فناوری فضایی, 2021
Adaptive control technique is taken into consideration because of overcoming the problem of existence of uncertainties in the space missions. In this paper, a novel optimal direct adaptive control technique which is based on Markov parameters is ...

Mobile Multi-Path Transmission Scheduling Algorithm Based on Grey Markov Prediction [PDF]

open access: yesJisuanji gongcheng, 2021
Multi-Path Control Transmission Protocol (MPTCP) improves resource utilization and network throughput by aggregating multi-path bandwidth.However,in the wireless heterogeneous network environment,out-of-order packets and buffer block are serious due to ...

An efficient probabilistic workflow for estimating induced earthquake parameters in 3D heterogeneous media [PDF]

open access: yesSolid Earth, 2022
We present an efficient probabilistic workflow for the estimation of source parameters of induced seismic events in three-dimensional heterogeneous media. Our workflow exploits a linearized variant of the Hamiltonian Monte Carlo (HMC) algorithm. Compared
