Hepatitis B Virus Disease: A Mathematical Model for Vertical Transmission with Treatment Strategy [PDF]
, 2016 This paper presents a mathematical model that captures some essential information about the impacts of treatment on hepatitis B vertical transmission. The treatment induced reproduction number is compared with the basic reproduction number to assess the ...

ℋ∞ constant gain state feedback stabilization of stochastic hybrid systems with Wiener process
Mathematical Problems in Engineering, Volume 2004, Issue 4, Page 333-345, 2004., 2004 This paper considers the stabilization problem of the class of continuous‐time linear stochastic hybrid systems with Wiener process. The ℋ∞ state feedback stabilization problem is treated. A state feedback controller with constant gain that does not require access to the system mode is designed.

Mathematical Problems in Engineering, Volume 2003, Issue 1, Page 25-45, 2003., 2003 We extend the notion of dissipative dynamical systems to formalize the concept of the nonlinear analog of strict positive realness and strict bounded realness. In particular, using exponentially weighted system storage functions with appropriate exponentially weighted supply rates, we introduce the concept of exponential dissipativity.

Mathematical Problems in Engineering, Volume 2003, Issue 4, Page 137-152, 2003., 2003 This paper deals with the class of uncertain systems with multiple time delays. The stability and stabilizability of this class of systems are considered. Their robustness are also studied when the norm‐bounded uncertainties are considered. Linear matrix inequality (LMIs) delay‐dependent sufficient conditions for both stability and stabilizability and ...

Impact of Hunting Cooperation and Fear Effect on a Tritrophic Food Chain Model
International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.Considering the importance of food chains in the environment from both biological and economic points of view, the life of a living organism depends on the existence of organisms that precede it. Many predators have also developed their own methods of obtaining food, although there is competition among them. Thus, studying hunting cooperation, which is

On eventual stability of impulsive systems of differential equations
International Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 8, Page 485-494, 2001., 2001 The notions of Lipschitz stability of impulsive systems of differential equations are extended and the notions of eventual stability are introduced. New notions called eventual and eventual Lipschitz stability. We give some criteria and results.

Computational and Mathematical Biophysics, 2023 The four-dimensional food-web system consisting of two prey species for a generalist middle predator and a top predator is proposed and investigated. The middle predator is predating over both the prey species with a modified Holling type-II functional ...
