1. On the relationship between psychometric intelligence and decision making in dynamic systems
Sammanfattning : The relationship between psychometric intelligence and performance in dynamic decision making systems (microworlds) was investigated. A theoretical analysis of the mental processes that underlie performance in intelligence tests and microworlds suggested that at least some weak positive correlations should be expected. LÄS MER
2. Computational topology optimization in continuum mechanics
Sammanfattning : This dissertation concerns theoretical and computational methodologies in topology optimization in continuum mechanics.A general procedure for treating problems of this kind starts with the establishment of a well-posed continuum problem formulation, in the sense that one can prove existence of at least one solution to the problem.

3. Failure of thin-walled structures under impact loading
Sammanfattning : Increase in computational power during recent years contributed to a significant development in numerical methods in mechanics. There are many methods developed that address various complex problems, yet modelling of initiation and propagation of failure in thin-walled structures requires further development. LÄS MER
4. Applications of Partial Polymorphisms in (Fine-Grained) Complexity of Constraint Satisfaction Problems
Sammanfattning : In this thesis we study the worst-case complexity ofconstraint satisfaction problems and some of its variants. We use methods from universal algebra: in particular, algebras of total functions and partial functions that are respectively known as clones and strong partial clones. LÄS MER
5. The spatial distribution of Lyman alpha from star-forming galaxies in the low redshift Universe
Sammanfattning : The Lyman alpha (Lyα) emission line from the recombination of hydrogen atoms is predicted to be the strongest spectral feature of galaxies. This emission line is regularly used to detect and characterise high redshift galaxies. However, studying this spectral line is challenging. LÄS MER
