1. Performance characterization and evaluation of parallel PDE solvers
Sammanfattning : Computer simulations that solve partial differential equations (PDEs) are common in many fields of science and engineering. To decrease the execution time of the simulations, the PDEs can be solved on parallel computers. For efficient parallel implementations, the characteristics of both the hardware and the PDE solver must be taken into account. LÄS MER
2. Exercise induced breathing problems in adolescents
Sammanfattning : Experiencing respiratory symptoms in conjunction with exercise is common in children and adolescents and can have a negative impact on daily life. The aim of the thesis was to estimate the prevalence of exercise-induced dyspnoea, exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (E-ILO) in a general adolescent population, and to explore factors associated with EIB.

3. Microfluidic and Molecular Tools for Genetic Analyses
Sammanfattning : Methods that enable interrogation of multiple genomic regions in parallel are very useful for efficient detection of genetic variation. Two different types of probes are described in this thesis that can be used for direct analysis or for sample preparation upstream of Next Generation Sequencing. LÄS MER
4. Autonomic Management of Partitioners for SAMR Grid Hierarchies
Sammanfattning : Parallel structured adaptive mesh refinement methods decrease the execution time and memory usage of partial differential equation solvers by adaptively assigning computational resources to regions with large solution errors. These methods result in a dynamic grid hierarchy. LÄS MER
5. Exploring Novel Catalytic Chalcogenide Antioxidants
Sammanfattning : This thesis is concerned with the synthesis and evaluation of regenerable chalcogen containing antioxidants. Variously substituted 2,3-dihydrobenzo[b]selenophene-5-ol antioxidants were evaluated in order to gain information about structure/reactivity-relationships. LÄS MER
