  1. 11. Pattern Recognition Methods for Oral Lesion Classification using Digital Color Images

    Författare :Artur Chodorowski; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oral lesions; supervised classification; pattern recognition; computer-aided diagnosis; support vector machines; color; cancer; shape;

    Sammanfattning : The present thesis addresses the development and application of pattern recognition methods for classification of oral lesions using digital color images as input. The human oral cavity is a site of numerous diseases and two of the common and visually similar lesions are oral leukoplakia and oral lichenoid reactions. LÄS MER

  2. 12. Salvage and de novo synthesis of nucleotides in Trypanosoma brucei and mammalian cells

    Författare :Artur Fijolek; Lars Thelander; Arne Holmgren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nucleotides; ribonucleotide reductase; Ara-A; p53R2; Trypanosoma brucei; African sleeping sickness; trypanosomiasis; CTP synthetase; adenosine kinase; acivicin; adenine arabinoside; Biochemistry; Biokemi;

    Sammanfattning : All living cells are dependent on nucleic acids for their survival. The genetic information stored in DNA is translated into functional proteins via a messenger molecule, the ribonucleic acid (RNA). Since DNA and RNA can be considered as polymers of nucleotides (NTPs), balanced pools of NTPs are crucial to nucleic acid synthesis and repair. LÄS MER

  3. 13. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure

    Författare :Artur Hedlund; Chalmers tekniska högskola; []

    Sammanfattning : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. LÄS MER

  4. 14. Improving Performance and Quality-of-Service through the Task-Parallel Model​ : Optimizations and Future Directions for OpenMP

    Författare :Artur Podobas; Mats Brorsson; Georgi Gaydadjiev; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Task Parallel; OpenMP; Scheduling; OmpSs; multicore; manycore; Datalogi; Computer Science;

    Sammanfattning : With the failure of Dennard's scaling, which stated that shrinking transistors will be more power-efficient, computer hardware has today become very divergent. Initially the change only concerned the number of processor on a chip (multicores), but has today further escalated into complex heterogeneous system with non-intuitive properties -- properties that can improve performance and power consumption but also strain the programmer expected to develop on them.
