To use face masks or not after Covid-19 vaccination? An impact analysis using mathematical modeling
(Frontiers Media, 2022)
The question of whether to drop or to continue wearing face masks especially after being
vaccinated among the public is controversial. This is sourced from the efficacy levels
of COVID-19 vaccines developed, approved, ...
A NSFD discretization of two-dimensional singularly perturbed semilinear convection-diffusion problems
(Frontiers Media, 2022)
Despite the availability of an abundant literature on singularly perturbed problems,
interest toward non-linear problems has been limited. In particular, parameter-uniform
methods for singularly perturbed semilinear ...
Mathematical study of transmission dynamics of SARS-CoV-2 with waning immunity
(AIMS Press, 2022)
The aim of this work is to provide a new mathematical model that studies transmission
dynamics of Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2). The model ...
A new parameter-uniform discretization of semilinear singularly perturbed problems
(MDPI, 2022)
In this paper, we present a numerical approach to solving singularly perturbed semilinear
convection-diffusion problems. The nonlinear part of the problem is linearized via the quasilinearization
technique. We then design ...
