VIBRATION ANALYSIS BY DISCRETE SINGULAR CONVOLUTION

Journal of Sound and Vibration, 2001
Summary: This paper explores the utility of a discrete singular convolution algorithm for vibration analysis. A number of different realizations of singular convolution kernels are selected to illustrate the present algorithm. Vibration analysis of strings, rods, beams, diatomic molecules, membranes, waveguides and thin plates are utilized to test ...

A generalized discrete singular convolution algorithm improved by regularizing singularities for one electron system

Chemical Physics Letters, 2009
A discrete singular convolution (DSC) algorithm was generalized from uniform discretization to nonuniform discretization by introducing a mapping method to regularize the singularities involved. The approach was demonstrated using a radial Schrodinger equation of a hydrogen atom with a Coulomb-like potential that involves a singularity.

Novel Symplectic Discrete Singular Convolution Method for Hamiltonian PDEs

Communications in Computational Physics, 2016
This paper explores the discrete singular convolution method for Hamiltonian PDEs. The differential matrices corresponding to two delta type kernels of the discrete singular convolution are presented analytically, which have the properties of high-order accuracy, bandlimited structure and thus can be excellent candidates for the spatial discretizations

Solving quantum eigenvalue problems by discrete singular convolution

Journal of Physics B: Atomic, Molecular and Optical Physics, 2000
This paper explores the utility of a discrete singular convolution (DSC) algorithm for solving the Schrodinger equation. DSC kernels of Shannon, Dirichlet, modified Dirichlet and de la Vallee Poussin are selected to illustrate the present algorithm for obtaining eigenfunctions and eigenvalues.

Discrete singular convolution for the solution of the Fokker–Planck equation

The Journal of Chemical Physics, 1999
This paper introduces a discrete singular convolution algorithm for solving the Fokker–Planck equation. Singular kernels of the Hilbert-type and the delta type are presented for numerical computations. Various sequences of approximations to the singular kernels are discussed.

Discrete singular convolution mapping methods for solving singular boundary value and boundary layer problems

The European Physical Journal Plus, 2017
A modified discrete singular convolution method is proposed. The method is based on the single (SE) and double (DE) exponential transformation to speed up the convergence of the existing methods. Numerical computations are performed on a wide variety of singular boundary value and singular perturbed problems in one and two dimensions.
