  1. 11. On the Dynamics of Porous Media - Application to Road and Railway Structures

    Författare :Bernd Lenhof; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poromechanics; dynamics; railway; multiphasic mixture; hydro-mechanical modeling; internal erosion; road; porous media;

    Sammanfattning : Load-bearing road and railway structures normally consist of layers of particulate porous materials, often with bitumen-based binders. The layered system is subjected to dynamic loading from traffic, which inevitably causes material deterioration that enhances permanent surface deformation. LÄS MER

  2. 12. Towards application of explicit likelihoods in inference for Dark Matter Direct Detection

    Författare :Pueh-Leng Tan; Jan Conrad; Klas Hultqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : Despite the many empirical hints for the existence of Dark Matter in the Universe, Dark Matter has yet to be observed experimentally, be it directly through its scatterings in detectors, indirectly through its annihilation in the galaxy, or implicitly through its production and decay in particle colliders. Even though observations from astrophysics and cosmology placed constraints on the Dark Matter energy density and self-interaction cross section and with Standard Model particles, much about the nature of Dark Matter is still unknown, leaving much to the creativity of model builders.

  3. 13. The environmental pressures of foods : Application in climate taxation and sustainability assessment of diets

    Författare :Emma Moberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Reducing environmental impacts from the food system will require a shift towards environmentally sustainable eating patterns. To achieve changes in diets that reduce environmental burdens, a climate tax on food has been suggested. LÄS MER

  4. 14. A DAE Formulation for Multi-Zone Thermodynamic Models and its Application to CVCP Engines

    Författare :Per Öberg; Lars Eriksson; Richard Stobart; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In the automotive area there are ever increasing demands from legislators and customers on low emissions and good fuel economy. In the process of developing and investigating new technologies, that can meet these demands, modeling and simulation have become important as standard engineering tools. LÄS MER

  5. 15. Domain-Informed Signal Processing with Application to Analysis of Human Brain Functional MRI Data

    Författare :Hamid Behjat; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :;

    Sammanfattning : Standard signal processing techniques are implicitly based on the assumption that the signal lies on a regular, homogeneous domain. In practice, however, many signals lie on an irregular or inhomogeneous domain. An application area where data are naturally defined on an irregular or inhomogeneous domain is human brain neuroimaging. LÄS MER
