Orthogonal-Based Second Order Hybrid Initial Value Problem Solver

open access: yesFountain Journal of Natural and Applied Sciences (FUJNAS), 2016
This work focuses on development of an initial value problem solver by employing a new class of orthogonal polynomial, the basis function. We present the recursive formula of the class of polynomials constructed and adopt collocation technique to ...

Acceleration of Runge‐Kutta integration schemes

open access: yesDiscrete Dynamics in Nature and Society, Volume 2004, Issue 2, Page 307-314, 2004., 2004
A simple accelerated third‐order Runge‐Kutta‐type, fixed time step, integration scheme that uses just two function evaluations per step is developed. Because of the lower number of function evaluations, the scheme proposed herein has a lower computational cost than the standard third‐order Runge‐Kutta scheme while maintaining the same order of local ...

Generalized solutions of the fractional Burger’s equation

open access: yesResults in Physics, 2019
We investigate the solutions for the fractional Burger’s equation based on the Jumarie fractional derivative using Bernoulli polynomials. We find general solutions for such problems. Comparison with other methods is presented.

Gaussian quadrature rules and A‐stability of Galerkin schemes for ODE

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 31, Page 1947-1959, 2003., 2003
The A‐stability properties of continuous and discontinuous Galerkin methods for solving ordinary differential equations (ODEs) are established using properties of Legendre polynomials and Gaussian quadrature rules. The influence on the A‐stability of the numerical integration using Gaussian quadrature rules involving a parameter is analyzed.
