  1. 21. Searches for Dark Matter and Large Extra Dimensions in Monojet Final States with the ATLAS Experiment

    Författare :Olof Lundberg; Christophe Clement; Shahram Rahatlou; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; bsm; gravity; extra dimensions; dark matter; ATLAS; LHC; fysik; Physics;

    Sammanfattning : This thesis presents searches for evidence for Weakly Interacting Massive Particles (WIMPs) and Extra Dimensions in proton-proton collisions recorded by the ATLAS experiment at the CERN Large Hadron Collider (LHC). The WIMP is one of the main candidates to constitute the particle content of Dark Matter. LÄS MER

  3. 22. A Search for Dark Matter Lines with H.E.S.S. II

    Författare :Knut Dundas Morå; Jan Conrad; Christian Farnier; Christian Walck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; Cherenkov Telescopes; Indirect Detection; fysik; Physics;

    Sammanfattning : Most of the matter in the universe, ~80% is thought to be dark matter- particles that have small or no interactions with standard model particles. Dark matter is an integral part of the current understanding of cosmology, and leaves signs in the movements of stars and galaxies, as well as the Cosmic Microwave Background. LÄS MER

  4. 23. Two topics in electromagnetic radiation field prospecting

    Författare :Bruno Nilsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : Different kinds of electrical methods have been used for a considerable time in the field of Applied Geophysics. In common these methods have almost exclusively been based on stationary or slow-varying electromagnetic fields. LÄS MER

  5. 24. Enhancing Direct Searches for Dark Matter : Spatial-Temporal Modeling and Explicit Likelihoods

    Författare :Bart Eduard Jan Pelssers; Jan Conrad; Jochen Schieck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; direct detection; statistical analysis; fysik; Physics;

    Sammanfattning : Astronomical and cosmological observations on different scales point to the existence of dark matter. In the current cosmological paradigm this dark matter accounts for about 26% of the energy-density of the universe, yet has not been directly observed. LÄS MER

  7. 25. Egocentric interaction for ambient intelligence

    Författare :Dipak Surie; Lars-Erik Janlert; Thomas Pederson; Hans Gellersen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ambient Intelligence; Human-Computer Interaction; Context-Aware computing; Ubiquitous Computing; Mixed-Reality; Smart Environments; Activity-Based Computing; Ambient Ecology; business data processing; administrativ databehandling;

    Sammanfattning : Ambient intelligence refers to the vision of computationally augmented everyday environments that are sensitive, adaptive and responsive to humans and intelligently support their daily lives. Ambient ecologies are the infrastructures of ambient intelligence. LÄS MER
