  2. 21. Search for Dark Matter and Extra Dimensions in Monojet Final States with the ATLAS Experiment

    Author : Olof Lundberg; Christophe Clement; Chad Finley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; LHC; ATLAS; Extra Dimension; Gravity; Calorimeter; High Energy Physics; högenergifysik;

    Abstract : The CERN Large Hadron Collider (LHC) is the most powerful particle ac- celerator ever built, in terms of luminosity and center-of-mass energy of the collisions. This thesis presents a search for Dark Matter and Extra Dimen- sions in the proton-proton collisions as recorded by the ATLAS detector. READ MORE

  5. 23. Satellite Radar Altimetry for Determination of Geoid Undulations and Gravity Anomalies

    Author : Jonas P. Noréus; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resolution; water vapour; geodesy; geoid undulations; gravity anomalies; precision; kriging; satellite remote sensing; radar altimetry;

    Abstract : The sea level changes both temporally (due to dynamic effects) and spatially (due to sea bottom topography and inhomogeneities in the Earth's crust). Satellite radar altimetry is a remote sensing technique which can be used for e.g. determination of the instantaneous and mean sea level, and gravity anomalies at sea. READ MORE

  6. 24. Regional Geoid Determination Methods for the Era of Satellite Gravimetry : Numerical Investigations Using Synthetic Earth Gravity Models

    Author : Jonas Ågren; Lars E. Sjöberg; Zdenek Martince; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; geoid determination; GOCE; synthetic earth gravity models; kernel modification; downward continuation; Geovetenskap; Earth sciences; Geovetenskap;

    Abstract : It is the purpose of this thesis to investigate different regional geoid determination methods with respect to their feasibility for use with a future GOCE satellite-only Earth Gravity Model (EGM). This includes investigations of various techniques, which involve different approximations, as well as the expected accuracy. READ MORE

  7. 25. Introducing Surface Gravity Waves into Earth System Models

    Author : Lichuan Wu; Anna Rutgersson; Erik Sahlée; Peter Janssen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface gravity waves; Air-sea interaction; Earth-System Model; Atmospheric mixing; Upper-ocean turbulence; Meteorologi; Meteorology;

    Abstract : Surface gravity waves alter the turbulence of the bottom atmosphere and the upper ocean. Accordingly, they can affect momentum flux, heat fluxes, gas exchange and atmospheric mixing. However, in most state-of-the-art Earth System Models (ESMs), surface wave influences are not fully considered or even included. READ MORE
