1. Multiscale and multilevel methods for porous media flow problems
Abstract : We consider two problems encountered in simulation of fluid flow through porous media. In macroscopic models based on Darcy's law, the permeability field appears as data.The first problem is that the permeability field generally is not entirely known. READ MORE

2. Numerical Methods for Darcy Flow Problems with Rough and Uncertain Data
Abstract : We address two computational challenges for numerical simulations of Darcy flow problems: rough and uncertain data. The rapidly varying and possibly high contrast permeability coefficient for the pressure equation in Darcy flow problems generally leads to irregular solutions, which in turn make standard solution techniques perform poorly.

3. Precambrian and Caledonian history of Svalbard’s West Ny Friesland Terrane
Abstract : This thesis deals mainly with age-investigations of metasedimentary and magmatic rocks of Ny Friesland, located in the northeastern Svalbard. However, the provenance of quartz-porphyry clasts in a Devonian conglomerate have also been investigated in northwestern Svalbard. READ MORE

4. Three Subfamilies of KRAB Zinc Finger Proteins : A Structural, Functional and Evolutionary Analysis
Abstract : Krüppel-related zinc finger proteins constitute the largest single class of transcription factors within the human genome. Members of this protein family have the ability to either activate or repress transcription depending on the presence of specific activator or repressor domains within the protein. READ MORE
