  1. 1. Top Quark Pair Production in ATLAS

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Karl Gellerstedt; Stockholms universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; top quark; LHC; ATLAS; Physics; fysik;

    Sammanfattning : The Large Hadron Collider (LHC) at the international particle physics laboratory CERN in Switzerland is currently the most powerful particle accelerator on earth. This thesis presents analyses of proton-proton collisions at the energy √s = 7 TeV, recorded by ATLAS, one of the detectors at the LHC. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; combustion; HCCI; reduction; engine; kinetic; simulation; graphical user interface; GUI; optimization; chemical mechanism; Physics; Fysik; Fysicumarkivet A:2004:Bellanca;

    Sammanfattning : The simulation of physical phenomena occurring in chemical reactors requires the description of the kinetics involved in the underlying combustion process. Kinetic models are developed for this purpose. LÄS MER

  3. 3. Spectroscopic techniques for photodynamic therapy dosimetry

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Ann Johansson; Lund University.; Lunds universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; diffuse light spectroscopy; photodynamic therapy; biomedical optics; Atom- och molekylärfysik;

    Sammanfattning : Photodynamic therapy (PDT) as a cancer treatment modality relies on the simultaneous presence of three components; light, photosensitiser and oxygen. Once excited by the light, the photosensitiser can interact with oxygen, leading to the formation of toxic oxygen species. LÄS MER

  4. 4. MRI evaluation and image processing in gel dosimetry. A study of selected MRI properties and image processing in 3D gel dosimetry

    Detta är en avhandling från Department of Radiation Physics, Lund university

    Författare :Peter Magnusson; Lund University.; Lunds universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; image registering; multi-slice; slice profile; ferrous sulphate; polyacrylamide; 3D volume acquisition; RF field; B1 field; relaxation time; T1; T2; spin-echo; multi-spin-echo; stochastic noise; nonuniformity; SNR; radiologi; tomografi; medicinsk instrumentering; Radiopharmaceutical technology; Radiofarmaceutisk teknik; Physics; Fysik;

    Sammanfattning : Gel dosimetry is a new dosimetry method applied in radiation therapy. Gel dosimeters consist of a radiation sensitive gel, which can integrate absorbed doses from several radiation sources or beams. The dose to the gel can be evaluated by magnetic resonance imaging (MRI), a procedure that is the focus of the present thesis. LÄS MER

  5. 5. A classifying algebra for CFT boundary conditions

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Carl Stigner; Karlstads universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary conditions; Conformal field theory; Factorization constraints; Modular tensor categories; TFT-construction; NATURAL SCIENCES Physics Other physics Mathematical physics; NATURVETENSKAP Fysik Övrig fysik Matematisk fysik; Physics; Fysik;

    Sammanfattning : Conformal field theories (CFT) constitute an interesting class of twodimensionalquantum field theories, with applications in string theoryas well as condensed matter physics. The symmetries of a CFT can beencoded in the mathematical structure of a conformal vertex algebra. LÄS MER
