Evaluation of overshooting errors in particle methods for diffusion by biased global random walk

8 years ago

AbstractThe adjustment of grid steps which guarantees that particles methods yield no numerical diffusion inevitably induces overshooting errors in the…

On the multi-decadal oscillation of Atlantic tropical storm activity

8 years ago

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

8 years ago

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

8 years ago

AbstractWe make use of two Laguerre collocation techniques as a way to illustrate, deepen or extend some analytic results of…

A survey on the high convergence orders and computational convergence orders of sequences

8 years ago

This is the first paper which surveys the rigorous definitions and relations of convergence orders (the Q-orders; the C-orders; the…

A modified Chebyshev-tau method for a hydrodynamic stability problem

8 years ago

AbstractWe study the linear stability of some Marangoni flows (thin films) on an inclined plane. The Orr-Sommerfeld eigenproblem contains two…

Application of the Jacobi-Davidson method to accurate analysis of singular linear hydrodynamic stability problems

8 years ago

AbstractThe aim of this paper is to show that the Jacobi–Davidson (JD) method is an accurate and robust method for…

On the Scalar Measure of Non-Normality of Matrices – Dimension vs. Structure

8 years ago

AbstractThe aim of this paper is to analyze the relative importance of the dimension and the structure of the square matrices…

On the behavior of a thin liquid layer flowing due to gravity and a surface tension gradient

8 years ago

AbstractA thin liquid layer flowing due to gravity and a surface tension gradient are taken into account. On the liquid/gas…

On the bifurcation and variational approximation of the positive solution of a nonlinear reaction-diffusion problem

8 years ago

Abstract We consider a nonlinear, second-order, two-point boundary value problem that models some reaction-diffusion processes. When the reaction term has…
