2. Evaluation of bus priority strategiesin coordinated traffic signal systems
Sammanfattning : Increasing congestion and environmental concerns have evoked an interest in promoting urban Public Transport (PT) the last decades. In 2012 the City of Stockholm adopted an “Urban mobility strategy” stating that public transport, cycling and walking should be prioritised over cars in central Stockholm. LÄS MER
3. On Approximating Asymmetric TSP and Related Problems
Sammanfattning : In this thesis we study problems related to approximation of asymmetric TSP. First we give worst case examples for the famous algorithm due to Frieze, Gabiati and Maffioli for asymmetric TSP with triangle inequality. Some steps in the algorithm consist of arbitrary choices. To prove lower bounds, these choices need to be specified. LÄS MER

Sammanfattning : Diabetes mellitus is a disorder with complex pathology and is frequently associated with vascular complications. In the islet micro milieu locally generated factors may affect both the physiology and the morphology of the tissue. LÄS MER
5. Structural and Interaction Studies of Bacterial Polysaccharides by NMR Spectroscopy
Sammanfattning : An introduction to bacterial polysaccharides and the methods for structural determination are described in the first two parts of the thesis.In a structural elucidation of bacterial polysaccharides NMR experiments are important as is component analysis. A short description of immunochemical methods such as enzyme immunoassays is included. LÄS MER
