In this paper, the operational matrix based on Bernstein wavelets is presented for solving
fractional SIR model with unknown parameters. The SIR model is a system of differential …

We seek investigate the use of fractional derivatives, both analytically and through
simulations. We present some models and perform investigations about them, starting with …

Background The world's survival ability has been threatened by the COVID-19 outbreak. The
possibility of the virus reemerging in the future should not be disregarded, even if it has been …

In this paper, a discrete fractional Susceptible-Infected-Treatment-Recovered-Susceptible
(SITRS) model for simulating the coronavirus (COVID-19) pandemic is presented. The …

This article presents the solution of the fractional SIR epidemic model using the Laplace
residual power series method. We introduce the fractional SIR model in the sense of …

In this study, we introduced a novel scheme to attain approximate and closed‐form solutions
of conformable Newell‐Whitehead‐Segel (NWS) equations, which belong to the most …

Some researchers have combined two powerful techniques to establish a new method for
solving fractional‐order differential equations. In this study, we used a new combined …

We aim in this research to determine the global stability of equilibrium states for an SIR
epidemic model with nonlocal diffusion and nonlinear incidence function in a …

In this article, a dynamical model with advection-diffusion, elucidating the transmission
process of disease infection type computer virus, is studied. Such kind of systems help to …

In this work, we examine two algorithm schemes, namely, Kudryashov expansion and
Auxiliary equation method for obtaining new optical soliton solutions of the discrete electrical …
