2. Atomic decomposition of molecular properties
Abstract : In this thesis, new methodology of computing properties aimed for multipleapplications is developed. We use quantum mechanics to compute propertiesof molecules, and having these properties as a basis, we set up equations basedon a classical reasoning. READ MORE

3. Ab initio modelling of interfaces in nanocomposites for high voltage insulation
Abstract : Dielectric nanocomposite materials have been experimentally proven to have properties that are beneficial in applications for efficient energy transport. However, today there are still no empirical models or rules that can predict the performance of a certain combination of materials in the nanocomposite, and there are also no definitive explanations of their dielectric behavior.

4. Light interactions in flexible conjugated dyes
Abstract : In this thesis methodological developments have been made for the description of flexible conjugated dyes in room temperature spectrum calculations.The methods in question target increased accuracy and efficiency by combining classical molecular dynamics (MD) simulations with time-dependent response theory spectrum calculations.

5. On drug use, multiple medication and polypharmacy in a national population
Abstract : The application of multiple medications has successively increased during a number of years and has thereby increased the potential risks of adverse drug reactions, interactions and non-adherence to drug therapy. This may result in unnecessary health expenditure, directly due to redundant drug sales, and indirectly due to the increased hospitalization caused by drug-related problems. READ MORE
