Numerical modelling of the one-dimensional diffusion by random walkers
AbstractIn this paper we describe a numerical method of cellular automaton type to study the diffusion processes. The macroscopic diffusive…
Evaluation of overshooting errors in particle methods for diffusion by biased global random walk
AbstractThe adjustment of grid steps which guarantees that particles methods yield no numerical diffusion inevitably induces overshooting errors in the…

AbstractLong term Atlantic tropical storm activity is described by the time series of the yearly Accumulated Cyclone Energy (ACE) Index…
Itô equation model for dispersion of solutes in heterogeneous media
AbstractTransport processes in heterogeneous media such as ionized plasmas, natural porous media, and turbulent atmosphere are often modeled as diffusion…
Laguerre collocation solutions vs. analytic results for singular semilinear BVPs on the half line
AbstractWe make use of two Laguerre collocation techniques as a way to illustrate, deepen or extend some analytic results of…
