  1. 1. Geoid Model of Tanzania from Sparse and Varying Gravity Data Density by the KTH method

    Författare :Prosper Ulotu; Lars Sjöberg; Hossein Nahavandchi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geoid; sparse gravity data; gravity database; GGM validation by gravity; corrector surface; hybrid geoid; KTH-LSMS with AC; Mt. Kilimanjaro; Tanzania.; Earth sciences; Geovetenskap;

    Sammanfattning : Developed countries are striving to achieve a cm geoid model. Most developing countries/regions think that the situation in their areas does not allow even a few decimetre geoid model. GNSS, which provides us with position, is one of the greatest achievements of the present time. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Airborne Gravity Gradient, Magnetic and VLF datasets : Case studies of modelling, inversion and interpretation

    Författare :Sayyed Mohammad Abtahi; Thomas Kalscheuer; Laust Pedersen; Jochen Kamm; Thorkild Rasmussen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VLF; gravity gradient; magnetic; airborne; inversion; non-uniqueness;

    Sammanfattning : Northern Sweden is one of the largest hosts for mineral resources in Europe and always has been an interesting area for researchers from various disciplines of Earth sciences. This dissertation is a comprehensive summary of three case study papers on airborne VLF, gravity gradient and magnetic data in the area. LÄS MER

  5. 4. Near surface atmospheric flow over high latitude glaciers

    Författare :Oskar Parmhed; Erland Källén; Branko Grisogono; Haraldur Ólafsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stable boundary layer; Ekman layer; Katabatic flow; gravity wave; low-level jets; Meteorology; Meteorologi;

    Sammanfattning : In this thesis various descriptions of the near surface atmospheric flow over a high latitude glacier is used in an effort to increase our understanding of the basic flow dynamics there. Through their contribution to sea-level change, mountain glaciers play a significant role in Earth’s climate system. LÄS MER

  7. 5. Chemical and Biochemical Biorefineries in Kraft Pulp Mills – Process Integration and Economics for Three Concepts

    Författare :Valeria Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bottleneck; ethanol; biorefinery; energy efficiency; process integration; pulp mill; high gravity;

    Sammanfattning : Some of the advantages of integrating biorefinery concepts with kraft pulp mills are that the utility system can be shared and that mass and energy streams can be exported from the pulp mill to the biorefinery or vice versa. These measures may result in lower investments and operating costs for the biorefinery compared with stand-alone operations. LÄS MER
