   Abstract : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. READ MORE

4. 2. Extensive tooth wear in adults : classification and prosthetic treatment

   Author : Wedad Hammoudi; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: Tooth wear (TW) is an insidious and cumulative mul- tifactorial process that may comprise erosion, abrasion or attrition, and combinations thereof. These different processes are of chemical or physical origin and not microbiological. READ MORE

5. 3. Bayesian inference in probabilistic graphical models

   Author : Felix Leopoldo Rios; Tatjana Pavlenko; Alun Thomas; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphical models; Bayesian inference; predictive classification; decomposable graphs; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

   Abstract : This thesis consists of four papers studying structure learning and Bayesian inference in probabilistic graphical models for both undirected and directed acyclic graphs (DAGs).Paper A presents a novel algorithm, called the Christmas tree algorithm (CTA), that incrementally construct junction trees for decomposable graphs by adding one node at a time to the underlying graph.

6. 4. Topological states of matter in low dimensions

   Author : Christian Spånslätt; Eddy Ardonne; Thors Hans Hansson; Karsten Flensberg; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

   Abstract : A central theme in condensed matter physics is the classification and characterization of states of matter. In the recent decades, it has become evident that there exists a large class of quantum mechanical systems that must be classified according to properties deeply rooted in the mathematical field of topology, rather than in terms of which symmetries they break.

7. 5. Environmental Factors of Importance in Myasthenia Gravis : Emphasis on Physical Activity

   Author : Elisabet Westerberg; Anna Rostedt Punga; Anne-Marie Landtblom; Chantal Tallaksen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myasthenia Gravis; MG subgroups; Environmental factors; Lifestyle; Physical activity; Exercise; Clinical Neurophysiology; Klinisk neurofysiologi;

   Abstract : Myasthenia Gravis (MG) is an autoimmune disease caused by antibodies directed against proteins at the neuromuscular junction (NMJ). The disturbed neuromuscular transmission induces fatigable weakness in skeletal muscles. READ MORE
