The main objective of this paper is to focus on a numerical study of unsteady boundary layer flow of Williamson Nanofluids over a heated permeable stretching sheet embedded in porous medium in the presence of viscous dissipation. A mathematical modeled wh... see more

In this study, fifth-order and sixth-order diagonally implicit Runge–Kutta type (DIRKT) techniques for solving fourth-order ordinary differential equations (ODEs) are derived which are denoted as DIRKT5 and DIRKT6, respectively. The first method has... see more

Research has been carried out on the visualization of harmonic and chaos phenomenont on coupled vibration physcal case using the Runge Kutta numerical computation method with the aim of applying the first to fourth order Runge Kutta computation method to ... see more

A recently developed meshless method, namely the radial basis function (RBF) combined with method of lines (MOL), i.e RBF MOL-RBF is used to find numerical solution of initial boundary value problems. Numerical examples are given to illustrate the practic... see more

Context. This article is devoted to the linear problem of the steady and unsteady flows of a viscous incompressible fluid.Objective. The purpose of this paper is to compare the previously developed methods of numerical analysis of the steady and unst... see more

In this research, the susceptible–infected–recovered (SIR) model of dengue fever is considered. We have implemented two analytical techniques, namely the variational iteration method (VIM) and the homotopy perturbation method (HPM) for solving the SIR mod... see more

Simulation of the trajectories of negative hydrogen ion (H-) beam in a 13 MeV PET cyclotron (DECY-13) were carried out by using the Runge-Kutta (RK4) approximation method and Scilab 5.4.1. The magnetic and electric fields were calculated using Opera-3d/TO... see more

This paper we are dealing with the high order accurate low storage explicit Runge Kutta (LSERK) methods which mainly are used for temporal discretization and are stable regardless of its accuracy. The main objective of this paper is to compare traditional... see more

This work touches two important cases for the motion of a pendulum called Sub and Ultra-harmonic cases. The small parameter method is used to obtain the approximate analytic periodic solutions of the equation of motion when the pivot point of the pendulum... see more
