چکیده

Abstract In this article, a meshless numerical technique based on radial basis functions (RBFs) is proposed for the solution of singular perturbed, obstacle, and second-order boundary value problems. First, unknown function their derivatives are approximated by RBFs which reduces given problem into system algebraic equations easy to solve. The shape parameter involved in chosen hit trial method. Despite this, convergence scheme briefly discussed numerically. nonlinear terms linearized quasi-linearization technique. main objective paper show that RBFs-based method convenient various classes Efficiency performance examined calculating absolute error norms. Obtained accurate results confirm applicability efficiency

Numerical Solution of Singularly Perturbed Two-Point Singular Boundary Value Problems Using Differential Quadrature Method

This paper presents the application of Differential Quadrature Method (DQM) for finding the numerical solution of singularly perturbed two point singular boundary value problems. The DQM is an efficient discretization technique in solving initial and/or boundary value problems accurately using a considerably small number of grid points. This method is based on the approximation of the derivativ...

B-Spline Solution of Boundary Value Problems of Fractional Order Based on Optimal Control Strategy

In this paper, boundary value problems of fractional order are converted into an optimal control problems. Then an approximate solution is constructed from translations and dilations of a B-spline function such that the exact boundary conditions are satisfied. The fractional differential operators are taken in the Riemann-Liouville and Caputo sense. Several example are given and the optimal err...
