AbstractThe available numerical algorithms for trend removal require a direct subjective intervention in choosing critical parameters. In this paper an…
AbstractThe Global random walk algorithm performs simultaneously the tracking of large collections of particles and permits massive simulations at reasonable…
AbstractIn this study we present a numerical analysis for the self-averaging of the longitudinal dispersion coefficient for transport in heterogeneous…

AbstractThe stochastic processes of finite length defined by recurrence relations request additional relations specifying the first terms of the process analogously to…
AbstractWe comparatively use some classical spectral collocation methods as well as highly performing Chebfun algorithms in order to compute the eigenpairs of second order singular Sturm-Liouville problems with separated self-adjoint…
AbstractWe are concerned with the study of some classical spectral collocation methods as well as with the new software system Chebfun in computing high order eigenpairs of singular and regular…
AbstractWe solve by Chebyshev spectral collocation some genuinely nonlinear Liouville-Bratu-Gelfand type, 1D and a 2D boundary value problems. The problems are formulated on the square domain [−1, 1] × [−1,…
