Robust dynamic output feedback fault-tolerant control for Takagi-Sugeno fuzzy systems with interval time-varying delay via improved delay partitioning approach

open access: yesOpen Mathematics, 2016
This paper addresses the problem of robust fault-tolerant control design scheme for a class of Takagi-Sugeno fuzzy systems subject to interval time-varying delay and external disturbances.

Global stability of a distributed delayed viral model with general incidence rate

open access: yesOpen Mathematics, 2018
In this paper, we discussed a infinitely distributed delayed viral infection model with nonlinear immune response and general incidence rate. We proved the existence and uniqueness of the equilibria.

A minimal HIV-AIDS infection model with general incidence rate and application to Morocco data

open access: yes, 2018
We study the global dynamics of a SICA infection model with general incidence rate. The proposed model is calibrated with cumulative cases of infection by HIV-AIDS in Morocco from 1986 to 2015.

Sensitivity to switching rates in stochastically switched ODEs [PDF]

open access: yes, 2014
We consider a stochastic process driven by a linear ordinary differential equation whose right-hand side switches at exponential times between a collection of different matrices.

Stability property of the prey free equilibrium point

open access: yesOpen Mathematics, 2019
We revisit a prey-predator model with stage structure for predator, which was proposed by Tapan Kumar Kar. By using the differential inequality theory and the comparison theorem of the differential equation, we show that the prey free equilibrium is ...

Asymptotic behavior of age-structured and delayed Lotka-Volterra models

open access: yes, 2020
In this work we investigate some asymptotic properties of an age-structured Lotka-Volterra model, where a specific choice of the functional parameters allows us to formulate it as a delayed problem, for which we prove the existence of a unique ...

On the dynamics of a class of multi-group models for vector-borne diseases [PDF]

open access: yes, 2015
The resurgence of vector-borne diseases is an increasing public health concern, and there is a need for a better understanding of their dynamics. For a number of diseases, e.g.

Global properties of virus dynamics with B-cell impairment

open access: yesOpen Mathematics, 2019
In this paper we construct a class of virus dynamics models with impairment of B-cell functions. Two forms of the incidence rate have been considered, saturated and general. The well-posedness of the models is justified.

Analysis of a fractional-order model for acute and chronic hepatitis-B transmission with Mittag-Leffler kernels

open access: yesComputational and Mathematical Biophysics
This study explores the dynamic characteristics of a fractional-order model for the hepatitis B virus (HBV) epidemic. We present the existence, uniqueness, and Ulam-Hyers stability of solutions for a fractional-order HBV model utilizing the Atangana ...
