  1. 1. Alternative techniques in trochanteric hip fracture surgery. Clinical and biomechanical studies on the Medoff sliding plate and the Twin hook

    Författare :Ola Olsson; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ortopedi; Kirurgi; traumatology; hip fracture; trochanteric; internal fixation; radiography; randomised trial; complication; biomechanics; orthopaedics; Surgery; traumatologi;

    Sammanfattning : In allowing compression along the femoral shaft (uniaxial dynamization) and optional compression along the femoral neck (biaxial dynamization), the Medoff sliding plate (MSP) represents a new principle in the fixation of trochanteric hip fractures. The Twin hook with 2 apical hooks was designed as an alternative to the lag screw. LÄS MER

  2. 2. Through the eyes of a woodpecker: Understanding habitat selection, territory quality and reproductive decisions from individual behaviour

    Författare :Ola Olsson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reproductive success; territory quality; habitat selection; giving-up density; Bayesian processes; foraging; Picidae; lesser spotted woodpecker; Dendrocopos minor; conservation; Animal ecology; Djurekologi;

    Sammanfattning : In this thesis I present some connections between foraging behaviour and reproductive success, time budget, tree species use, and habitat selection. The thesis is based upon both theoretical and empirical work. All empirical studies concern a south Swedish population of lesser spotted woodpeckers Dendrocopos minor, studied between 1990 and 1996.

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Growth theory; knowledge; human capital; technology; university policy; biogeography; epistemology; long-run development;

    Sammanfattning : This thesis deals with various aspects of the relationship between knowledge and economic growth. It contains a general introduction and five separate essays. Essay I is a literature overview on the appearance of knowledge in modern growth theory. LÄS MER

  4. 4. The HCCI Engine – High Load Performance and Control Aspects

    Författare :Jan-Ola Olsson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Identification; Motors and propulsion systems; Motorer; framdrivningssystem; Real Time; Black-Box Model; LQG; Closed-Loop Control; Internal Combustion Engine; Emissions; EGR; Efficiency; HCCI; Homogeneous Charge Compression Ignition;

    Sammanfattning : Current combustion engines provide excellent performance for vehicle propulsion and power generation. However, recent demands from society ask for higher efficiencies and lower emissions. These requirements are hard to meet with current technology and call for new solutions. LÄS MER

  5. 5. Real-Time Shading and Accurate Shadows Using GPGPU Techniques

    Författare :Ola Olsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virtual shadow-maps; real time; transparency; shading; shadows; rendering; shadow volumes; GPGPU; GPU;

    Sammanfattning : Over the last 10-15 years, computer graphics hardware has evolved at a tremendous pace, with an exponential growth in the number of transistors. This evolution has transformed the Graphics Processing Unit (GPU) from an entirely fixed-function unit into a highly parallel general-purpose architecture that can be programmed using high-level programming languages.
