1. 11. Towards Joint Super-Resolution and High Dynamic Range Image Reconstruction

   Författare :Tomas Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Super-resolution; Dynamic range; Human visual system; Inverse problem; Image reconstruction; Spatial alignment; Photometric alignment; Digital camera system;

   Sammanfattning : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

3. 12. The use of structural information to improve biological sequence similarity searches

   Författare :Jeanette Tångrot; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatik; Hidden Markov Model; HMM; protein structure alignment; protein structure superimposition; remote homologue; FISH-server; protein annotation; Bioinformatics; Bioinformatik;

   Sammanfattning : Bioinformatics is a fast-developing field that make use of computational methods to analyse and structure biological data. An important branch of bioinformatics is structure and function prediction of proteins. To determine the structure of a protein is a crucial part in the characterisation of the molecule. LÄS MER

4. 13. Sequence-based predictions of membrane-protein topology, homology and insertion

   Författare :Andreas Bernsel; Gunnar von Heijne; Volkhard Helms; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane protein; topology prediction; hidden markov model; homology detection; Sec translocon; Bioinformatics; Bioinformatik; Biochemistry; biokemi;

   Sammanfattning : Membrane proteins comprise around 20-30% of a typical proteome and play crucial roles in a wide variety of biochemical pathways. Apart from their general biological significance, membrane proteins are of particular interest to the pharmaceutical industry, being targets for more than half of all available drugs. LÄS MER

5. 14. A Study in RNA Bioinformatics : Identification, Prediction and Analysis

   Författare :Eva Freyhult; David Ardell; Robert Giegerich; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA; bioinformatics; secondary structure; structure prediction; dynamic programming; energy landscape; homology search; sequence logo; tRNA; Bioinformatics; Bioinformatik;

   Sammanfattning : Research in the last few decades has revealed the great capacity of the RNA molecule. RNA, which previously was assumed to play a main role only as an intermediate in the translation of genes to proteins, is today known to play many important roles in the cell in addition to that as a messenger RNA and transfer RNA, including the ability to catalyze reactions and gene regulations at various levels.
