  1. 1. Ulcerative Colitis - Surgery Outcome and Pathophysiological Aspects

    Författare :Mattias Block; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ulcerative Colitis; Long-term Function; IPAA; IRA; Neoplasia; Surveillance; Primary Sclerosing Cholangitis; Galectins; Immunohistochemistry;

    Sammanfattning : Background: Ulcerative Colitis (UC) is a chronic inflammatory bowel disease; the etiology is mainly unknown. Around 30% of the patients are treated by surgery. The aims of this thesis were to evaluate outcome after specific surgical procedures and to investigate possible pathophysiological aspects. LÄS MER

  4. 3. Ternary Codes with Weight Constraints

    Författare :Mattias Svanström; Faina Solovieva; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We study the problem of maximizing the size of a ternary block code with given length and minimum Hamming distance. The problem is further restricted in two different ways. Either we require all codewords to have constant Hamming weight, or we require all codewords to have constant composition. LÄS MER

  5. 4. Integrated Software Pipelining

    Författare :Mattias Eriksson; Christoph Kessler; Sid Ahmed Ali Touati; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Code generation; compilers; instruction scheduling; register allocation; spill code generation; modulo scheduling; integer linear programming; genetic programming.; Computer science; Datavetenskap;

    Sammanfattning : In this thesis we address the problem of integrated software pipelining for clustered VLIW architectures. The phases that are integrated and solved as one combined problem are: cluster assignment, instruction selection, scheduling, register allocation and spilling. LÄS MER

  7. 5. On MIMO Systems and Adaptive Arrays for Wireless Communication : Analysis and Practical Aspects

    Författare :Mattias Wennström; Michael A. Jensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; antenna array; calibration; MIMO system; flat fading; non-linear amplifier; switched parasitic antenna; analog beamformer; adaptive antenna testbed; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

    Sammanfattning : This thesis is concerned with the use of multiple antenna elements in wireless communication over frequency non-selective radio channels. Both measurement results and theoretical analysis are presented. New transmit strategies are derived and compared to existing transmit strategies, such as beamforming and space-time block coding (STBC). LÄS MER
