  3. 7. Visual function in very low birth weight adolescents : fifteen-year follow-up of children in southeast Sweden

    Författare :Kerstin Hellgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Very low birth weight (VLBW < 1500 g) carries an increased risk of visual and cognitive deficits. Long term follow-up studies are sparse. The associations between neural structure and visual and cognitive outcome need to be more fully explored. LÄS MER

  4. 8. Calibration and orientation of airborne image and laser scanner data using GPS and INS

    Författare :Helén Burman; KTH; []
    Nyckelord :;

    Sammanfattning : GPS and INS measurements provide positions and attitudesthat can be used for direct orientation of airborne sensors.This research improves the final results by performingsimultaneous adjustments of GPS, INS and image or laser scannerdata. LÄS MER

  5. 9. On failure of high strength steel bridge roller bearings

    Författare :Pourya Noury; Ove Lagerqvist; Kjell Eriksson; John Yates; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Sammanfattning : This thesis is concerned with failure analysis of high strength steel bridge roller bearings.Paper Adescribes how the commonly used Hertz formulas for contact stresses underestimate the actual stresses in practice due to temperature differences, misalignments and other construction-related conditions.
