Stability of the modified Craig–Sneyd scheme for two-dimensional convection–diffusion equations with mixed derivative term

in 't Hout, K.J.; Mishra, C. - In: Mathematics and Computers in Simulation (MATCOM) 81 (2011) 11, pp. 2540-2548

The modified Craig–Sneyd (MCS) scheme is a promising splitting scheme of the ADI type for multi-dimensional pure diffusion equations having mixed spatial-derivative terms. In this paper we investigate the extension of the MCS scheme to two-dimensional convection–diffusion equations with a...

Initial-boundary value problems of warped MPDAEs including minimisation criteria

Pulch, R. - In: Mathematics and Computers in Simulation (MATCOM) 79 (2008) 2, pp. 117-132

multidimensional signal model yields a description via multirate partial differential-algebraic equations (MPDAEs). Initial-boundary … value problems of the MPDAE system reproduce solutions of the underlying DAE system. In case of frequency modulation, an …

Modelling and numerical simulation of contamination processes in random media

Belleni Morante, A.; Lauro, G.; Monaco, R. - In: Mathematics and Computers in Simulation (MATCOM) 42 (1996) 1, pp. 85-95

A Boltzmann-like model for the description of processes of outgassing and contamination is proposed. The cavity /oR2, where the contaminants migrate during their motion from the source region /oR1 to the target /oR3, contains a random medium.
