    Sammanfattning : The effects of climate change are already being felt today, and future effects, which will be determined by the readiness and resolve of today’s world leaders, are fraught with high levels of complexity, uncertainty, ambiguity, and transboundary effects – characteristics of systemic risk. Since climate change is seen as a threat multiplier, the risks that might be impacted by climate change, such as floods and dam failure, will be affected by systemic risk characteristics as well.

  3. 12. A study of some energy dependent characteristics of X-ray screens used in diagnostic radiology : screen-film sensitivity, MTF and some related factors

    Författare :Mikael Karlsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensifying screens; x-ray screens; fluorescent screens; modulation transfer function; MTF; x-ray screen sensitivity; fluorescent K-radiation sources;

    Sammanfattning : Fluorescent x-ray screens are used in medical x-ray diagnostics to absorb x-ray photons and convert these x-ray photons to visible light. The light distribution from these screens are then registered on photographic film to give an x-ray image. LÄS MER

    Sammanfattning : Flooding is of great concern world-wide, causing damage to infrastructure, property and loss of life. Low-income countries, in particular, can be negatively affected by flood events due to their inherent vulnerabilities. Moreover, data to perform studies for flood risk management in low-income regions are often scarce or lacking sufficient quality. LÄS MER

  5. 14. Finite element analysis of thin-walled structures subjected to impact loading

    Författare :Mats Oldenburg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : This thesis is devoted to the numerical solution of dynamic problems involving thin-walled structures. Special consideration is paid to the effects of contact-impacts. LÄS MER

  7. 15. Stability and Receptivity of Three-Dimensional Boundary Layers

    Författare :David Tempelmann; Dan Henningson; Stefan Hein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; stability; optimal growth; three-dimensional boundary layers; parabolised stability equations; adjoint PSE; crossflow instability; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The stability and the receptivity of three-dimensional flat plate boundary layers is studied employing parabolised stability equations. These allow for computationally efficient parametric studies. Two different sets of equations are used. LÄS MER
