Spatial Stabilization of Semidiscrete Elastodynamics
2008Solutions of direct time integration schemes that converge in time to conventional semidiscrete formulations may be polluted at small time steps by noncausal oscillations. These pathologies are the deleterious effects of higher modes of spatially discrete formulations, which are approximated poorly.

Recurrence in Semidiscrete Approximations of the Nonlinear Schrödinger Equation
SIAM Journal on Scientific and Statistical Computing, 1987The use of numerical methods is investigated for a study of recurrence in the nonlinear Schrödinger equation. A spectral, a pseudospectral and a finite difference method are shown to conserve discrete analogues of two of the conservation laws satisfied by this equation.

Semidiscrete pesticide transport modeling and application
Journal of Hydrology, 2004A time-continuous and space-discrete method is proposed for three-phase (dissolved, adsorbed, and vapor phases) pesticide transport modeling in the vadose zone and a generalized semidiscrete solution is derived under conditions of heterogeneous media, unsteady flow fields, and space-time-dependent physical and biochemical processes concerning pesticide

Convergence Estimates for Semidiscrete Parabolic Equation Approximations
SIAM Journal on Numerical Analysis, 1982Semidiscrete methods for approximating the solutions of initial boundary value problems for parabolic equations are studied. The construction of these semidiscrete methods is based upon the availability of several different Galerkin type approximation methods for the associated elliptic steadystate problem.

Semidiscrete and Discrete Well-Posedness of Shock Filtering
2005While shock filters are popular morphological image enhancement methods, no well-posedness theory is available for their corresponding partial differential equations (PDEs). By analysing the dynamical system of ordinary differential equations that results from a space discretisation of a PDE for 1-D shock filtering, we derive an analytical solution and

On the Existence of Semidiscrete Shock Profiles
2001The approximation of shock waves by finite difference schemes is considered. This question has been investigated by many authors, but mainly under some restrictions on discrete wave speeds. Basic works are due to Majda and Ralston (rational speed) and, more recently, to Liu and Yu (Diophantine speed).
