  2. 1. Lower Extremity Function in Arthritis

    Author : Ann Bremander; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reumatologi; muskelsystem; Skelett; rheumatology locomotion; muscle system; Skeleton; Knee injury; Arthritis; Reliability; Self-registered physical function; Validity; Observed physical function; Physical medicine; Rehabilitering medicinsk och social ; kinesitherapy; revalidation; rehabilitation;

    Abstract : The aim of this thesis was to develop and apply self-registered and observed measures of physical function in people with arthritis in the lower extremity. In Paper I, 181 subjects from the Swedish Knee Arthroplasty Register who were satisfied with their primary knee arthroplasty were studied. READ MORE

  4. 2. Distance Functions and Their Use in Adaptive Mathematical Morphology

    Author : Vladimir Ćurić; Gunilla Borgefors; Cris L. Luengo Hendriks; Hugues Talbot; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Distance functions; Mathematical morphology; Adaptive mathematical morphology; Image regularization; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : One of the main problems in image analysis is a comparison of different shapes in images. It is often desirable to determine the extent to which one shape differs from another. This is usually a difficult task because shapes vary in size, length, contrast, texture, orientation, etc. Shapes can be described using sets of points, crisp of fuzzy. READ MORE

  5. 3. Essays on Distance Based (Non-Euclidean) Tests for Spatial Clustering in Inhomogeneous Populations : Adjusting for the Inhomogeneity through the Distance Used

    Author : Ulla Romild; Johan Lyhagen; Anders Ågren; Jack Cuzick; Uppsala universitet; []
    Keywords : Statistics; Clustering; Spatial Point Pattern; Inhomogeneous Density; Statistik;

    Abstract : This thesis consits of four papers dealing with distance based (non-Euclidean) tests for spatial clustering in inhomogeneous populations. The density adjusted distance (DAD), which considers the underlying density, is defined in the first paper. READ MORE

  6. 4. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function

    Author : Carolin Freccero; Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; wavelength; sympathetic vasodilatation; sympathetic vasoconstriction; sympathetic nerve function; parasympathetic nerve function; laser Doppler perfusion imaging; laser Doppler perfusion monitoring; finger skin blood flow; fibre separation; contralateral cooling; Concentration; Fysiologi; Cardiovascular system; Kardiovaskulära systemet; Diagnostik; Diagnostics;

    Abstract : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. READ MORE

  7. 5. Assessment of active commuting behaviour : walking and bicycling in Greater Stockholm

    Author : Erik Stigell; Peter Schantz; Andreas Nilsson; Maria Hagströmer; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; walking; cycling; commuting; validity; reproducibility; distance; duration; velocity; frequency; seasonality; Sports; Idrott; Samhällsvetenskap Humaniora; Social Sciences Humanities; Sports Science;

    Abstract : Walking and bicycling to work, active commuting, can contribute to sustainable mobility and provide regular health-enhancing physical activity for individuals. Our knowledge of active commuting behaviours in general and in different mode and gender groups in particular is limited. READ MORE
