  1. 1. Beamforming and timing design issues for a large aperture array radar applied to atmospheric research

    Författare :Gustav Johansson; Jan Bergman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : This thesis describes the work done by the author during the development of a Large Aperture Array Radar (LAAR) receiver for the EISCAT 3D project. The main focus was on digital beamforming of a bandpass-sampled wide band signal in base-band and the development of a picosecond-level distributed timing system applicable over hundreds of meters.

  3. 2. Computational modeling of magnetic materials and alloys

    Författare :Gustav Johansson; Andreas Larsson; Corina Etz; Sergey Simak; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Physics; Tillämpad fysik;

    Sammanfattning : Magnetic materials play an important part in modern technology, appearing practically everywhere. Nonetheless, there is a need to discover new magnetic materials that can make devices faster, use less energy, and store more data. For this reason, computational modeling is an important tool.

  4. 3. Ultrasensitive DNA sequencing using liquid biopsies enables precision medicine

    Författare :Gustav Johansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liquid biopsy; cell-free DNA; immune repertoire; next-generation sequencing; unique molecule identifier; GIST; γδ T cell;

    Sammanfattning : Liquid biopsies are minimally invasive and allow repetitive sampling of body fluids. Analysis of cell-free tumor DNA in liquid biopsies can be used as a biomarker for cancer. However, in most clinically relevant liquid biopsies, cell-free DNA is present at low concentrations, contains minute tumor allele frequencies, and is highly fragmented. LÄS MER

  5. 4. Factors Affecting the Distribution of Rocky-Shore Macroalgae on the Swedish Coast : Morphological, Physiological, Reproductive and Genetic Aspects

    Författare :Gustav Johansson; John Raven; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The aim of this thesis was to examine factors affecting the distribution of macroalgal species both vertically (depth zonation) and geographically along the Baltic Sea salinity gradient. Interactions between the physical environment and basic biological traits of the algae are emphasised. LÄS MER
