Numerical solutions of a non-Fickian diffusion equation belonging to a hyperbolic type are presented in one space dimension. The Brownian particle modelled by this diffusion equation is subjected to a symmetric periodic potential whose spatial shape can be varied by a single parameter. We consider a numerical method which consists of applying Laplace transform in time; we then obtain an elliptic diffusion equation which is discretized using a finite difference method. We analyze some aspects of… 

A hybrid numerical method for a two-dimensional second order hyperbolic equation

Second order hyperbolic differential equations have been used to model many problems that appear related to heat conduction, mass diffusion and fluid dynamics. In this work a numerical method is

A numerical approach to study the Kramers equation for finite geometries: boundary conditions and potential fields

The Kramers equation for the phase-space function, which models the dynamics of an underdamped Brownian particle, is the subject of our study. Numerical solutions of this equation for natural

A Meshless and Parallelizable Method for Differential Equations with Time-Delay

This talk proposes a method for a class of time-delay problems, which is completely meshless, representing the solution by its Laplace inverse transform along a carefully designed contour in the complex plane and then approximating the contour integral by the Filon-Clenshaw-Curits (FCC) quadrature in a few fast growing subintervals.

Numerical solution of the Helmholtz equation with high wavenumbers

This paper investigates the pollution effect, and explores the feasibility of a local spectral method, the discrete singular convolution (DSC) algorithm for solving the Helmholtz equation with high

Transport process of ions in insulating media in the hyperbolic diffusion regime.

It is shown that, in the hyperbolic diffusion regime approximation, new trends for the real and imaginary parts of the small-signal electrical impedance of a dielectric containing ions versus the frequency of the applied voltage are expected when the delay time is comparable with the Debye relaxation time.

It is proved that, in two and more space dimensions, it is impossible to eliminate the so-called pollution effect of the Galerkin FEM.

We consider a Brownian particle in a periodic potential under heavy damping. The second law forbids it from displaying any net drift speed, even if the symmetry of the potential is broken. But if the

A flexible efficient and accurate inverse Laplace transform algorithm is developed that computes the coefficients of the continued fractions needed for the inversion process by combining diagonalwise operations and recursion relations in the quotient-difference schemes.

The critical nonlinear Schrodinger equation (NLS) models the propagation of intense laser light in Kerr media. This equation is derived from the more comprehensive nonlinear Helmholtz equation (NLH)

Numerical Inversion of Laplace Transforms Using a Fourier Series Approximation

A method is presented for numerically inverting a Laplace transform that requires, in addition to the transform function itself, only sine, cosine, and exponential functions and includes a transformation of the approximating series into one that converges very rapidly.
