The Bivariate Modified Exponential Geometric Distribution: Model, Properties and Applications
(Islamic Azad University, Central tehran Branch, 2021-12-01)In this paper, we have introduced a five‐parameter bivariate model by taking a geometric minimum of the modified exponential distributions. It is observed that the maximum likelihood estimators of the unknown parameters ...

Analysis of a Three Age Group Preys with Control Measures of COVID-19 Spread in the Third Prey
(Islamic Azad University, Central tehran Branch, 2021-12-01)In this paper we study the covid-19 disease with treatment and control to spread it with different measures. The model equations are analysed from the general MC Kendrick equations for age structured populations. The ...

Advanced Refinements of Numerical Radius Inequalities
(Islamic Azad University, Central tehran Branch, 2021-12-01)By taking into account that the computation of the numerical radius is an optimization problem, we prove, in this paper, several refinements of the numerical radius inequalities for Hilbert space operators. It is shown, ...

Numerical Solution of Nonlinear System of Ordinary Differential Equations by the Newton-Taylor Polynomial and Extrapolation with Application from a Corona Virus Model
(Islamic Azad University, Central tehran Branch, 2021-12-01)In this paper, we consider a nonlinear non autonomous system of differential equations. We linearize this system by the Newton's method and obtain a sequence of linear systems of ODE. We are going to solve this system on ...
