Yellow virus epidemiological analysis in red chili plants using Mittag-Leffler kernel
This scientific study investigates to check the dynamical behavior of yellow virus in red chilli with fractional order techniques. While attempts are being made to stop the yellow virus pandemic, a more infectious yellow virus found in red chilli is ...

Numerical bifurcation analysis of a class of nonlinear renewal equations [PDF]
We show, by way of an example, that numerical bifurcation tools for ODE yield reliable bifurcation diagrams when applied to the pseudospectral approximation of a one-parameter family of nonlinear renewal equations.

Positivity preservation of implicit discretizations of the advection equation [PDF]
We analyze, from the viewpoint of positivity preservation, certain discretizations of a fundamental partial differential equation, the one-dimensional advection equation with periodic boundary condition.

Fractional mathematical modeling of the Stuxnet virus along with an optimal control problem
In this digital, internet-based world, it is not new to face cyber attacks from time to time. A number of heavy viruses have been made by hackers, and they have successfully given big losses to our systems.

Computing the eigenvalues of realistic Daphnia models by pseudospectral methods [PDF]
This work deals with physiologically structured populations of the Daphnia type. Their biological modeling poses several computational challenges. In such models, indeed, the evolution of a size structured consumer described by a Volterra functional ...

The Essential Stability of Local Error Control for Dynamical Systems [PDF]
Although most adaptive software for initial value problems is designed with an accuracy requirement—control of the local error—it is frequently observed that stability is imparted by the adaptation.
