1. Numerical Analysis of Evolution Problems in Multiphysics
Sammanfattning : In this thesis we study numerical methods for evolution problems in multiphysics. The term multiphysics is commonly used to describe physical phenomena that involve several interacting models. Typically, such problems result in coupled systems of partial differential equations.

2. Volatile metabolites from microorganisms in indoor environments : sampling, analysis and identification
Sammanfattning : Microorganisms are able to produce a wide variety of volatile organic compounds. This thesis deals with sampling, analysis and identification of such compounds, produced by microorganisms commonly found in buildings. LÄS MER
3. Subspace Computations via Matrix Decompositions and Geometric Optimization
Sammanfattning : This thesis is concerned with the computation of certain subspaces connected to a given matrix, where the closely related problem of approximating the matrix with one of lower rank is given special attention. To determine the rank and obtain bases for fundamental subspaces such as the range and null space of a matrix, computing the singular value decomposition (SVD) is the standard method. LÄS MER
4. Essays on Social Capital, Health and Socioeconomic Inequalities in Health A Health Economic Study
Sammanfattning : The thesis comprises four independent research papers and a summary that focus on two related dimensions. The first dimension focuses on the understanding of the production of health. Particularly, the question is asked whether community's stock of social capital influence individual's health. LÄS MER
5. Homogenization of some problems in hydrodynamic lubrication involving rough boundaries
Sammanfattning : This thesis is devoted to the study of some homogenization problems with applications in lubrication theory. It consists of an introduction, five research papers (I–V) and a complementary appendix.Homogenization is a mathematical theory for studying differential equations with rapidly oscillating coefficients.
