Optimal control and bifurcation diagram for a model nonlinear fractional SIRC [PDF]

open access: yesAlexandria Engineering Journal, 2020
In this article, the optimal control for nonlinear SIRC model is studied in fractional order using the Caputo fractional derivative. Graph signal flow is given of the model and simulated by Simulink/Matlab which helps in discussing the topological ...

A Generalized ML-Hyers-Ulam Stability of Quadratic Fractional Integral Equation

open access: yesNonlinear Engineering, 2021
An interesting quadratic fractional integral equation is investigated in this work via a generalized Mittag-Leffler (ML) function. The generalized ML–Hyers–Ulam stability is established in this investigation.

Metastable energy strata in numerical discretizations of weakly nonlinear wave equations [PDF]

open access: yes, 2016
The quadratic nonlinear wave equation on a one-dimensional torus with small initial values located in a single Fourier mode is considered. In this situation, the formation of metastable energy strata has recently been described and their long-time ...

New Caputo-Fabrizio fractional order SEIASqEqHR model for COVID-19 epidemic transmission with genetic algorithm based control strategy

open access: yesAlexandria Engineering Journal, 2020
Fractional derivative has a memory and non-localization features that make it very useful in modelling epidemics’ transition. The kernel of Caputo-Fabrizio fractional derivative has many features such as non-singularity, non-locality and an exponential ...

A universal constitutive model for the interfacial layer between a polymer melt and a solid wall [PDF]

open access: yes, 2003
In a preceeding report we derived the evolution equation for the bond vector probability distribution function (BVPDF) of tethered molecules. It describes the behavior of polymer molecules attached to a solid wall interacting with an adjacent flowing ...

Numerical Methods That Preserve a Lyapunov Function for Ordinary Differential Equations [PDF]

open access: yes, 2022
The paper studies numerical methods that preserve a Lyapunov function of a dynamical system, i.e., numerical approximations whose energy decreases, just like in the original differential equation.

A robust numerical method to study oscillatory instability of gap solitary waves [PDF]

open access: yes, 2004
The spectral problem associated with the linearization about solitary waves of spinor systems or optical coupled mode equations supporting gap solitons is formulated in terms of the Evans function, a complex analytic function whose zeros correspond to ...

Modulated rotating waves in the magnetized spherical Couette system [PDF]

open access: yes, 2019
We present a study devoted to a detailed description of modulated rotating waves (MRW) in the magnetized spherical Couette system. The set-up consists of a liquid metal confined between two differentially rotating spheres and subjected to an axially ...
