Global stability of the positive equilibrium for a non-cooperative model of nuclear reactors
Electronic Journal of Qualitative Theory of Differential Equations, 2012 In this paper, we investigate the non-cooperative reaction-diffusion model of nuclear reactors subject to the homogeneous Neumann boundary condition. By establishing appropriate Lyapunov functions, we prove the global stability of the unique positive ...

Stability of HIV-1 Dynamics Models with Viral and Cellular Infections in the Presence of Macrophages
Axioms, 2023 In this research work, we suggest two mathematical models that take into account (i) two categories of target cells, CD4+T cells and macrophages, and (ii) two modes of infection transmissions, the direct virus-to-cell (VTC) method and cell-to-cell (CTC ...

Global stability analysis and stabilization of power amplifiers [PDF]
2008 Microwaves, Radar and Remote Sensing Symposium, 2008 Power amplifiers often exhibit undesired behavior from certain input power value which cannot be predicted with a small-signal stability analysis. Among the commonly observed undesired phenomena are spurious oscillations, frequency divisions, hysteresis or chaos.

Susceptible-Infected-Treatment model with disease infection in prey population recovered by treatment [PDF]
Computational Ecology and Software, 2022 This paper describes a mathematical model with Susceptible-Infected-Treatment under disease infection in prey population. The controls methods are one is separating control that is to separate the prey from infected prey by means of self quarantine and ...

International Journal of Applied Mathematics and Computer Science, 2022 In this paper, we propose a multi-group SEIR epidemic model with spatial diffusion, where the model parameters are spatially heterogeneous. The positivity and ultimate boundedness of the solution, as well as the existence of a global attractor of the ...
