  1. 16. Colonic Diverticulitis : Diagnostic and Therapeutic Aspects

    Författare :Abbas Chabok; Kenneth Smedh; Tom Öresland; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Kirurgi;

    Sammanfattning : The overall aims of this thesis were to evaluate diagnostic and therapeutic aspects of colonic diverticulitis. In the first study, a systematic review of the literature was performed to evaluate radiological diagnostics for patients with acute left-sided diverticulitis. LÄS MER

  2. 17. Performance Analysis and Design Space Exploration of On-Chip Interconnection Networks

    Författare :Abbas Eslami Kiasari; Axel Jantsch; Joerg Henkel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The advance of semiconductor technology, which has led to more than one billion transistors on a single chip, has enabled designers to integrate dozens of IP (intellectual property) blocks together with large amounts of embedded memory. These advances, along with the fact that traditional communication architectures do not scale well have led to significant changes in the architecture and design of integrated circuits. LÄS MER

  3. 18. On the treatment of tibial shaft fractures

    Författare :Abbas Karladani; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cast; Distraction; Dynamometry; Fracture; Limb lengthening; Nailing; Outcome; Psychometry; Shaft; Soft tissue; Tibial;

    Sammanfattning : The aim of this thesis was to evaluate those factors, which have predictive value for development of complications after tibial shaft fractures, and to evaluate the outcome of the available treatment methods for closed, as well as open tibial shaft fractures associated with extensive soft-tissue injury. To determine the factors, which influence healing speed, we reviewed 100 consecutive patients with 104 tibial shaft fractures tibial shaft fractures. LÄS MER

  4. 19. Computational analysis and design optimization for acoustic devices

    Författare :Abbas Mousavi; Eddie Wadbro; Martin Berggren; Niels Aage; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; computational analysis; viscothermal acoustics; material distribution topology optimization; acoustic black holes; finite element method;

    Sammanfattning : This thesis focuses on material distribution topology optimization for acoustic waveguides. The limitations of the material distribution approach are discussed in the context of acoustic waveguides with extensive viscous and thermal boundary losses. LÄS MER

  5. 20. Compact RF Integration and Packaging Solutions Based on Metasurfaces for Millimeter-Wave Applications

    Författare :Abbas Vosoogh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The millimeter-wave frequency range has got a lot of attention over the past few years because it contains unused frequency spectrum resources that are suitable for delivering Gbit/s end-user access in areas with high user density. Due to the limited output power that the current RF active components can deliver in millimeter-wave frequencies, antennas with the features of low profile, high gain, high efficiency and low cost are needed to compensate free space path loss and increase the communication distance for the emerging high data rate wireless systems.
