A method based on the SCT to solve the inverse problem for heat equation
Articles in Press, Accepted Manuscript, Available Online from 02 December 2021
Abstract
In this article, a mathematical model of the inverse problem is considered. Basedon this model a formulation of inverse problem for heat equation is proposed.Shifted Chebyshev Tau (SCT) method is suggested to solve the inverse problem. The aim of this determined effort is to identify unknown function ... Read MoreA Mathematical Model on the Spread of COVID-19
Articles in Press, Accepted Manuscript, Available Online from 17 July 2023
Abstract
In this paper, a nonlinear mathematical model of COVID-19 was formulated. We proposed a SEIQR model using a system of ordinary differential equations. COVID-19 free equilibrium and endemic equilibrium points of the model are obtained. A basic reproduction number of the model is investigated by the next-generation ...

Volume 9, Issue 3 , July 2022, , Pages 231-248
Abstract
In this paper, optimal control problem is applied to Human Papillomavirus (HPV) and Herpes Simplex Virus type 2 (HSV-2) coinfection model formulated by a system of ordinary differential equations. Optimal control strategy is employed to study the effect of combining different intervention strategy on ... Read MorePoisson regression model with change points
Volume 8, Special Issue , November 2021, , Pages 1-8
Abstract
There are many different fields the change point analysis arises. In those cases, the main problem is locating the unknown change points. The aim of this study is to detect location and time of change point in Poisson regression model. We assume for years before and after the change point , then observation ...

Volume 8, Issue 1 , March 2021, , Pages 90-103
Abstract
In this paper, a one-dimensional fractional advection-diffusion equation is considered. First, we propose a numerical approximation of the Riemann-Liouville fractional derivative which is fourth-order accurate, then a numerical method for the fractional advection-diffusion equation using a high order ...

Volume 6, Issue 1 , April 2019, , Pages 80-86
Abstract
Spur gears are the most well-known kind of gears used in hybrid vehicle’s power transmission. They have straight teeth and are mounted on parallel shafts. In some cases, many spur gears are utilized without a moment's delay to make huge rigging decreases. In this paper how stress creates on a spur ...
