1. To survive and reproduce in a cyclic environment – demography and conservation of the Arctic fox in Scandinavia
Sammanfattning : This thesis concerns the conservation and life history of the Arctic fox (Vulpes lagopus) in Scandinavia. The Arctic fox was historically a widely distributed species in the Scandinavian mountain tundra with a population size of approximately 10 000 individuals during years with high resource availability, i.e. rodent peaks.

2. Biotic and abiotic stress in microorganisms and plants: Some Mechanisms of Stress and Programmed Cell Death. Genetic Engineering Approaches Towards Improved Stress Tolerance
Sammanfattning : Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. LÄS MER
3. Creating Knowledge with Data Science for Design in Systems
Sammanfattning : Designing in large-scale engineering systems is a difficult cognitive task undertaken by experts. Knowledge of experts continually changes as they are confronted with similar by different problems in designing in such systems. LÄS MER
4. Evaluation and Modelling of Short Haul Intermodal Transport Systems
Sammanfattning : Conventional intermodal rail freight transport systems have proved themselves competitive and able to offer cost-leadership on long distances and in endpoint relations between two nodes. Several studies within intermodal transports have made contributions in finding the minimum distance, the “break-even” distance that an intermodal door-to-door shipment can compete with unimodal road.

5. Riemann-Hilbert methods in general relativity and random matrix theory
Sammanfattning : This thesis focuses on problems in general relativity and random matrix theory that can be solved by means of Riemann-Hilbert techniques. The first part of the thesis is dedicated to solving boundary value problems related to colliding plane waves in vacuum in general relativity. LÄS MER
