Partial Contraction Analysis of Coupled Fractional Order Systems
Autor: Ahmad Ruzitalab, Mohammad Hadi Farahi, Gholamhossien Erjaee
Publikováno v: Journal of Applied Mathematics, Vol 2018 (2018)
Contraction theory regards the convergence between two arbitrary system trajectories. In this article we have introduced partial contraction theory as an extension of contraction theory to analyze coupled identical fractional order systems. It can, a

A different approach of optimal control on an HIV immunology model
Autor: Masoud Roshanfekr, Mohammad Hadi Farahi, Raheleh Rahbarian
Publikováno v: Ain Shams Engineering Journal, Vol 5, Iss 1, Pp 213-219 (2014)
A system of ordinary differential equation, which describes the interaction of HIV and T cells in the immune system, is utilized, and optimal representing drug treatment strategies of this model are explored. Control model, in the sense of an optimal

A suboptimal control of linear time-delay problems via dynamic programming
Autor: Atefeh Gooran Orimi, Sohrab Effati, Mohammad Hadi Farahi
Publikováno v: IMA Journal of Mathematical Control and Information. 39:675-707
We study a class of infinite horizon optimal control problems with a state delay, and investigate the dynamic programming approach which leverages the sufficient optimality conditions and provides a closed-loop solution. Importantly, the well-known L

An efficient approximate method for solving two-dimensional fractional optimal control problems using generalized fractional order of Bernstein functions
Autor: Sohrab Effati, Ali Ketabdari, Mohammad Hadi Farahi
Publikováno v: IMA Journal of Mathematical Control and Information. 38:378-395
We define a new operational matrix of fractional derivative in the Caputo type and apply a spectral method to solve a two-dimensional fractional optimal control problem (2D-FOCP). To acquire this aim, first we expand the state and control variables b

An approximate method based on Bernstein polynomials for solving fractional PDEs with proportional delays
Autor: Ali Ketabdari, Mohammad Hadi Farahi, Sohrab Effati
Publikováno v: Iranian Journal of Numerical Analysis and Optimization, Vol 10, Iss 2, Pp 223-239 (2020)
We apply a new method to solve fractional partial differential equations (FPDEs) with proportional delays. The method is based on expanding the unknown solution of FPDEs with proportional delays by the basis of Bernstein polynomials with unknown cont

Parkinson's Disease Rating Scale Using Synchronization Analysis of Gait Dynamics
Autor: Naeimehossadat Asmarian, Mohammad Hadi Farahi, Gholamhossien Erjaee, Ahmad Ruzitalab, Seyyed Mojtaba Asmarian
Publikováno v: BioMed Research International
BioMed Research International, Vol 2021 (2021)
Analysis of gait dynamics is a noninvasive and totally painless test, and it can be an ideal method for the diagnosis of neurodegenerative diseases. In this study, based on the strength of synchronization between dynamics of strides, we have suggeste
