  1. 1. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions

    Författare :Alireza Nickman; Bo Olofsson; Per-Erik Jansson; Nils-Otto Kitterød; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; Flood; Moisture; Temperature; Groundwater; GIS; Uncertainity; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.

    Sammanfattning : Household and corporate behaviour under uncertainty is examined in five self-contained essays. Thefirst four essays are focused on household behaviour with an emphasis on the role of housing and thelast essay is on optimal corporate financial in relation to the tax system. LÄS MER

  4. 3. Λ-Λ hyperons: the road to estimate the production cross-section in protonproton collisions

    Författare :Gandharva Appagere; Maria Doncel Monasterio; Per-Erik Tegnér; Michael Papenbrock; Andreas Heinz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hyperons; multi-strangeness; neutron-stars; cross-section; Lambda-lambda; Physics; fysik;

    Sammanfattning : In this study, we analyse the $\Lambda$-$\Lambda$ hyperon channel in proton-proton scattering, $pp \mapsto \Lambda\Lambda + K^+K^+, \,\,\Lambda\mapsto p+\pi^-$, with a proton beam energy of $4.5$ GeV using the High Acceptance Di-Electron Spectrometer (HADES) at GSI. LÄS MER
