Abstract
  In this paper, we proposed a numerical approach to solve a distributed order time fractional COVID 19 virus model. The fractional derivatives are shown in the Caputo-Prabhakar contains generalized Mittag-Leffler Kernel. The coronavirus 19 disease model has 8 Inger diets leading to system of 8 nonlinear ...  Read More

Abstract
  This paper, presents a mathematical model of a four-level supply chain under hyperchaos circumstances. The analysis of this model shows that the hyper-chaotic supply chain has an unstable equilibrium point. Using Lyapunov's theory of stability, the problem of designing a hyperchaotic supply chain control ...  Read More

Volume 7, Issue 3 , September 2020, , Pages 301-312

https://doi.org/10.22105/jarie.2021.244715.1188

Abstract
  In this paper we have studied a numerical approximation to the solution of the nonlinear Burgers' equation. The presented scheme is obtained by using the Non-Standard Finite Difference Method (NSFD). The use of NSFD method and its approximations play an important role for the formation of stable numerical ...  Read More

Volume 4, Issue 2 , October 2017, , Pages 75-76

https://doi.org/10.22105/jarie.2017.100848.1023

Abstract
  In [1] the authors have set up a bio-economic equilibrium model to understand the interactions between three fish populations and seek to maximize the profits of fishermen. The authors then studied the existence of stationary states and their stability using eigenvalue analysis. This is not correct in ...  Read More
