Sammanfattning : Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medical image segmentation.

Sammanfattning : This thesis is carried out within two projects ‘Statistical modelling and intelligentdata sampling in Magnetic resonance imaging (MRI) and positron-emission tomography(PET) measurements for cancer therapy assessment’ and ‘WindCoE -Nordic Wind Energy Center’ during my PhD study. It mainly focuses on applicationsof Bayesian hierarchical models (BHMs) and theoretical developments ofcompressive sensing (CS). LÄS MER
Sammanfattning : Diabetic neuropathy is a condition associated with diabetes affecting the epidermal nerve fibers (ENFs). This thesis presents analysis methods and models for ENF data, with two main puroposes: to find early signs of diabetic neuropathy and to characterize how this condition changes the nerve fiber structure.

Sammanfattning : The overall purpose of the thesis is to describe the development of the Swedish system of measuring cognitive abilities applied at enlistment of conscripts. The Enlistment Battery has been used for more than fifty years to classify 18-year old men into military positions for their compulsory service. LÄS MER
Sammanfattning : The main objective of the thesis was to develop and applymethodologies for analysis and evaluation of the applicabilityof different types of road traffic simulation models for urbantraffic conditions. For this purpose a number of models ofmacroscopic, mesoscopic and microscopic type were applied,calibrated, validated and analyzed using extensive field datacollection to obtain traffic flow, travel time and queue-lengthdata for major road networks in Stockholm and Uppsala.
