Studying a fractional order model to investigate the effect of drug treatment on HIV control [PDF]

open access: yesریاضی و جامعه, 2022
In this paper, a fractional order model is presented to study the effect of the drug therapy on the control of HIV infection. For this purpose, we calculate the reproduction number of the model with the next generation operator method and by using that ...

Significance of Ramped Temperature in the Dynamics of Unsteady Viscoelastic Fluid Subjected to Lorentz Force

open access: yesFrontiers in Physics, 2022
Viscoelastic fluids, such as polymers, paints, and DNA suspensions, are almost everywhere and very useful in the industry. This article aims to study the significance of ramped temperature in the dynamics of viscoelastic fluid.

The role of relaxation and retardation phenomenon of Oldroyd-B fluid flow through Stehfest’s and Tzou’s algorithms

open access: yesNonlinear Engineering, 2022
Delayed response (delay of the elasticity) and time needed for initial stress can lead to relaxation and retardation phenomenon; this is because of the consistent behavior of viscoelastic fluid on thermodynamic principles.

A note on fractional linear pure birth and pure death processes in epidemic models [PDF]

open access: yes, 2011
In this note we highlight the role of fractional linear birth and linear death processes recently studied in \citet{sakhno} and \citet{pol}, in relation to epidemic models with empirical power law distribution of the events.

A fractional B-spline collocation method for the numerical solution of fractional predator-prey models [PDF]

open access: yes, 2018
We present a collocation method based on fractional B-splines for the solution of fractional differential problems. The key-idea is to use the space generated by the fractional B-splines, i.e., piecewise polynomials of noninteger degree, as approximating
