1. 1. Improving Multi-Atlas Segmentation Methods for Medical Images

   Författare :Jennifer Alvén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supervised learning; semantic segmentation; multi-atlas segmentation; conditional random fields; label fusion; feature-based registration; image registration; random decision forests; convolutional neural networks; medical image segmentation;

   Sammanfattning : Semantic segmentation of organs or tissues, i.e. delineating anatomically or physiologically meaningful boundaries, is an essential task in medical image analysis. One particular class of automatic segmentation algorithms has proved to excel at a diverse set of medical applications, namely multi-atlas segmentation. LÄS MER

3. 2. Labeling, tagging and charging - Long standing issues in bioenergetics addressed with novel techniques

   Författare :Tobias Gustavsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WrbA; site specific labeling; fusion proteins; spectro electrochemistry; succinate quinone reductase; NADH quinone oxidoredictase; cytochromes; Respiratory chain;

   Sammanfattning : Understanding the molecular details of bioenergetic processes is fundamentally important. Defects in the mitochondrial energy metabolism can lead to untimely apoptosis and thus cause serious degenerative human diseases. LÄS MER

4. 3. Semantic mapping using virtual sensors and fusion of aerial images with sensor data from a ground vehicle

   Författare :Martin Persson; Achim Lilienthal; Javier González; Örebro universitet; []
   Nyckelord :semantic mapping; aerial image; mobile robot; supervised learning; semi-supervised learning; TECHNOLOGY; TEKNIKVETENSKAP; Industriell mätteknik; Industrial Measurement Technology;

   Sammanfattning : In this thesis, semantic mapping is understood to be the process of putting a tag or label on objects or regions in a map. This label should be interpretable by and have a meaning for a human. The use of semantic information has several application areas in mobile robotics. LÄS MER

5. 4. Functional screening and molecular characterisation of small proteins

   Författare :Dörte Schlesinger; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Proteins are one of the main drivers of cellular function. Most known proteins constitute various hundred amino acids, but growing evidence suggests that additionally thousands of short open reading frames (sORFs) are translated, posing the exciting possibility that many small unknown proteins are yet to be discovered.

7. 5. A Novel Route for Construction of Multipurpose Receptors through Chemical Modification of Glutathione Transferases

   Författare :Johan Viljanen; Bengt Harald Jonsson; Kerstin Broo; Sophia Hober; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human GST A1-1; site-specific covalent modification; tyrosine 9; lysine 216; methionine 208; multipurpose receptor; pattern recognition; protein purification; Chemistry; Kemi;

   Sammanfattning : This thesis describes how the human Alpha class glutathione transferase (GST) A1-1 can be reprogrammed either to function as a multipurpose biosensor for detection of small molecule analytes, or as a handle providing for more efficient protein purification.A novel, user-friendly, and efficient method for site-specific introduction of functional groups into the active site of hGST A1-1 is the platform for these achievements.
