  1. 1. Seismic high-frequency content loads on structures and components within nuclear facilities

    Författare :Cecilia Rydell; Anders Ansell; Mario Plos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear power plant; Earthquake; Seismic high frequencies; Fluid-structure interaction; Piping; Concrete; Pool;

    Sammanfattning : Sweden is generally considered to be a low seismicity area, but for structures within nuclear power facilities, the safety level demand with respect to seismic events are high and thus, these structures are required to be earthquake-resistant. The seismic hazard is here primarily considered to be associated with near-field earthquakes. LÄS MER

  5. 4. From Icon to Identity. Scottish Piping & Drumming in Scandinavia

    Författare :Mats d Hermansson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; bagpipe; drum; pipe band; icon; identity; Scandinavia; Scotland; Highland; function of music; imaginary world; impact of music; insider; outsider; learning music; learning music.;

    Sammanfattning : In the 1960s, a few individuals in Scandinavia got so interested in Scottish Highland piping and pipe band drumming that they started to play themselves, although there was no existing tradition for this music in Scandinavia, and they formed a small community of dedicated pipers and drummers. The major objective of this thesis is to analyse the background to why and processes through which the marginal culture of Scottish piping and drumming spread to and developed in Scandinavia as well as to interrogate what use and function this genre of music may have in Scandinavia.

  7. 5. On the Simulation of Progressive Deformation in Nuclear Piping

    Författare :Andreas Gustafsson; Jan Granlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : In this thesis the performance of different constitutive models in ratchet simulation is investigated. Ratcheting is accumulated plastic strains which may occur when a structure is subjected to a constant load in combination with cyclic loading. LÄS MER
