In this work, we propose a mathematical model that describes liver evolution and concentrations of alanine aminotransferase and aspartate aminotransferase in a group of rats damaged with carbon tetrachloride. Carbon tetrachloride was employed to indu

In this article, an approach to modeling dynamical systems in case of unknown governing physical laws has been introduced. The systems of differential equations obtained by means of a data-driven algorithm are taken as the desired models. In this c

In this paper we consider two type of mathematical models for the novel coronavirus (2019-nCov), which are in the form of a nonlinear differential equations system. In the first model the contact rate, , and transition rate of symptomatic infected in

Abstract In this article, we present an approach to solve a wide range of nonlinear equations formulated in extended b-metric spaces based on a new fixed-point theorem on these spaces. This research effort was motivated by challenges arising in solvi

The model of the spread of the coronavirus pandemic in the form of a system of integro-differential equations is studied. We focus our consideration on the number of hospitalized patients, i.e., on the needs of the system regarding hospital beds that

In this article, we want to find the analytic approximate solution of nonlinear problems by using Homotopy Perturbation Method. Using the Homotopy Perturbation Method once we express the nonlinear problem into infinite number of sub linear problems a

GENERATION OF A DIFFERENTIAL EQUATIONS SYSTEM TO SIMULATE THE KINETICS OF A COMPLEX CHEMICAL PROCESS
The solution of the inverse kinetic task based on formal kinetics was not often implemented in the past due to the need for a large volume of calculations, which even with the advent of computers were not performed at an acceptable rate. Such a situa

On the basis of previously built kinetic model of changes in genetic controlling systems in cells at their proliferation and differentiation, it was held that these changes take place on gene, chromosome, membrane and ion levels. The mathematic descr
