A Comparison between Euler's Method and 4-th Order Runge- Kutta Method For Numerical Solutions of Neutrosophic and Dual Differential Problems [PDF]

Neutrosophic Sets and Systems
This paper is dedicated to study some numerical solutions of neutrosophic and dual differential problems through a numerical comparison between neutrosophic Euler's method and 4-th order Runge-Kutta neutrosophic and dual method, where we apply both ...

Numerical Solution of Stochastic Hyperbolic Equations

Abstract and Applied Analysis, 2012
A two-step difference scheme for the numerical solution of the initial-boundary value problem for stochastic hyperbolic equations is presented. The convergence estimate for the solution of the difference scheme is established.

Numerical Solution for an Epicycloid Crack

Journal of Applied Mathematics, 2014
A flat crack, Ω, is lying in a three-dimensional homogenous isotropic elastic solid subjected to shear loading. A mathematical formulation is developed based on the mixed boundary values for Ω such that the problem of finding the resulting force can be ...

Direct numerical simulation of turbulence at lower costs [PDF]

, 1995
Direct Numerical Simulation (DNS) is the most accurate, but also the most expensive, way of computing turbulent flow. To cut the costs of DNS we consider a family of second-order, explicit one-leg time-integration methods and look for the method with the
