  1. 1. Experimental and numerical study of deformations and stresses in butt-welded plates

    Författare :Mikael Jonsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : Deformations and stresses in butt-welding of plates are studied. Temperatures, strains, residual stresses and change in gap width in front of the heat source are calculated and measured. In particular, the change in gap width in front of the heat source during welding and residual stresses after welding are studied. LÄS MER

  3. 2. TM-rolling of heavy plate and roll wear

    Författare :Mikael Jonsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik; Heavy plate;

    Sammanfattning : The heavy plate rolling process needs accurate predictions of the process parameters. The plate thickness, flatness and rolling stability are of this direct influenced as well as the productivity. Therefore, careful calculation of the process parameters and pass schedules is necessary. LÄS MER

  4. 3. Landskapets röster : Studier i Elias Martins bildvärld

    Författare :Mikael Ahlund; Hedvig Brander Jonsson; Emilie Karlsmo; Sten Åke Nilsson; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Landscape painting; 18th century Swedish art; 18th century British art; 18th century Sweden; Gustav III; art markets; travel writing; word image.; Art; Konstvetenskap; Konstvetenskap; History of Art;

    Sammanfattning : This thesis is about the Swedish landscape painter Elias Martin (1739-1818). The main interest is in his depictions of nature, landscape images and topographical views. Chronologically, it covers the period 1760 to 1810. LÄS MER

  5. 4. Minimally Invasive Catheter-Based Technologies

    Författare :Mikael Sandell; Göran Stemme; Staffan Holmin; Niclas Roxhed; Wouter van der Wijngaart; Stefan Jonsson; Duncan Maitland; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk teknologi; Medical Technology;

    Sammanfattning : A simple incision procedure in a blood vessel makes the entire vascular system accessible. Through contrast injection and X-ray visualization, the vascular tree can be mapped and navigated through manual manipulation of thin tubes and wires. LÄS MER

  7. 5. Integration of MRI into the radiotherapy workflow

    Författare :Joakim Jonsson; Tufve Nyholm; Mikael Karlsson; Magnus Karlsson; Uulke van der Heide; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; magnetic resonance imaging; radiotherapy; treatment planning; image registration; workflow; radiofysik; radiation physics;

    Sammanfattning : The modern day radiotherapy treatments are almost exclusively based on computed tomography (CT) images. The CT images are acquired using x-rays, and therefore reflect the radiation interaction properties of the material. LÄS MER
