16. Colonic Diverticulitis : Diagnostic and Therapeutic Aspects
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
17. Performance Analysis and Design Space Exploration of On-Chip Interconnection Networks
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
18. On the treatment of tibial shaft fractures
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
19. Computational analysis and design optimization for acoustic devices
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
20. Compact RF Integration and Packaging Solutions Based on Metasurfaces for Millimeter-Wave Applications
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.
