1. Studies on stable angina pectoris : risk indicators, prognosis and effects of verapamil or metoprolol treatment
Sammanfattning : Hemostatic and fibrinolytic variables, inflammatory parameters, catecholamines and lipid parameters were studied at baseline, in a long-term prospective study of 809 patients with stable angina pectoris, and compared to results obtained in healthy control subjects (n=50). The prognostic implications of the various parameters at baseline were evaluated, as well as possible influences of drug treatment on these variables and their prognostic implications were studied.

2. Large Eddy Simulations of Separated Compressible Flows around Wing Sections
Sammanfattning : This thesis concerns numerical calculations of compressible separated flows, with and without shocks, around wing sections using Large Eddy Simulations (LES). The considered geometries are the NACA 0012 wing section and the ONERA AT15A wing section. LÄS MER
3. Epidemiological studies of Helicobacter pylori and its relation to cancer and precancerous lesions in the upper gastrointestinal tract
Sammanfattning : Helicobacter pylori infection is strongly associated with gastric cancer risk. The carcinogenic process is supposed to occur step by step, from a normal gastric epithelium via gastritis, atrophy, intestinal metaplasia to dysplasia. LÄS MER
4. Modelling of drug-effect on time-varying biomarkers
Sammanfattning : Model-based quantification of drug effect is an efficient tool during pre-clinical and clinical phases of drug trials. Mathematical modelling can lead to improved understanding of the underlying biological mechanisms, help in finding shortcomings of experimental design and suggest improvements, or be an effective tool in simulation-based analyses.

5. Fuel-Efficient Look-Ahead Control for Heavy-Duty Vehicles with Varying Velocity Demands
Sammanfattning : The fuel consumption of heavy-duty vehicles can be reduced by using information about the upcoming road section when controlling the vehicles. Most manufacturers of heavy-duty vehicles today offer such look-ahead controllers for highway driving, where the information consists of the road grade and the velocity only has small variations.
