  1. 21. Computational methods for on-line shape inspection

    Författare :Per Bergström; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Teknisk-vetenskapliga beräkningar;

    Sammanfattning : This licentiate thesis describes computational methods that solve problems occurring in industrial on-line shape quality inspection of produced items. These items are measured and compared with their corresponding CAD object. The meaning of on-line is that the inspection is done on-line in the production line, i.e. LÄS MER

  4. 23. Dynamic consequences of shape deviations in hydropower generators

    Författare :Niklas Lundström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : Earlier measurements on hydropower generators have indicated the existence of backward whirling motion, and, also relatively large shape deviations in both the rotor and the stator. These non-symmetric geometries produce an attraction force between the rotor and the stator, called unbalanced magnetic pull (UMP). LÄS MER

  5. 24. Optical Characterization of Solar Collectors form Outdoor Measurements

    Författare :Anna Helgesson; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Due to high installation costs and relatively low output, the active use of solar energy is limited. The output from a collector can be improved e.g. by using a selective absorber, AR-treated cover glass or transparent insulation. LÄS MER

  7. 25. Hand function in children and in persons with neurological disorders : aspects of movement control and evaluation of measurements

    Författare :Elisabeth Svensson; Charlotte Häger-Ross; Birgitta Lindmark; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebellum; disability; hand function; hereditary motor and sensory neuropathies; latency; motor control; reactive control; reproducibility; sensation; strength; Physiotherapy; Sjukgymnastik fysioterapi;

    Sammanfattning : Hand function is of great importance in the many daily activities that require well-coordinated hand and arm movements. Measurement of hand function is an essential element in the rehabilitation process, in order to facilitate medical diagnosis and determine developmental stages, functional levels, and the efficacy of treatment interventions.
