Stochastic models and Monte Carlo algorithms for simulation of flow through porous media beyond the small hydraulic conductivity fluctuation assumptions are developed. The hydraulic conductivity is modelled as an isotropic ...

As observed on the Earth's surface, the magnetic field can be separated into three components: The "Main Field", the "Crustal Field"; and the "External Magnetic Field". This work concentrates on the magnetospheric current ...

Stochastic earthquake models are often based on a marked point process approach as for instance presented in Vere-Jones (1995). This gives a fine resolution both in space and time making it possible to represent each ...

We describe a Voronoi box based finite volume method for the numerical simulation of thermal convection in sedimental basins. The method shows a temperature maximum principle and consistent velocity approximation. We present ...

Motivated by seismological problems we have studied a 4th order split scheme for the elastic wave equation. We split in the spatial directions and obtain locally one-dimensional systems to be solved. We have analyzed the ...
