  1. 6. Efficient algorithms for highly automated evaluation of liquid chromatography - mass spectrometry data

    Författare :Mattias Fredriksson; Dan Bylund; Patrik Petersson; Bengt-Olof Axelsson; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital filtering; Liquid chromatography; Mass spectrometry; Method; Chemistry; Kemi;

    Sammanfattning : Liquid chromatography coupled to mass spectrometry (LC‐MS) has due to its superiorresolving capabilities become one of the most common analytical instruments fordetermining the constituents in an unknown sample. Each type of sample requires a specificset‐up of the instrument parameters, a procedure referred to as method development. LÄS MER

  3. 7. Testing palaeomagnetic and 14C based geochronological methods in the Baltic Sea

    Författare :Bryan Lougheed; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; coastal; geochronology; palaeomagnetic secular variation; PSV; radiocarbon; 14C; reservoir age; R t ; ΔR; salinity; δ18O; geomagnetic field; Holocene; deglacial; Fennoscandia.;

    Sammanfattning : The Baltic Sea is a continental shelf sea that is influenced by both river runoff and marine water. The two water masses are vertically stratified in the Baltic Sea, resulting in a positive, estuarine circulation system, which has undergone changes in the past due to isostatic uplift of the Baltic basin.

  4. 8. In-Line Bit Interleaved Serially Concatenated Coded Modulation

    Författare :ANDERS NILSSON; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; serially concatenated codes; the AWGN channel.; Coded modulation; iterative decoding; in-line bit interleaving; turbo codes;

    Sammanfattning : A communication system using in-line bit interleaved serially concatenated trellis coded modulation (SCTCM) over the additive white Gaussian noise (AWGN) channel is investigated. In-line bit interleaving refers to an interleaving method for which the random bit interleaver is divided into several independent constituent bit interleavers. LÄS MER

  5. 9. Supernova surroundings on circumstellar and galactic scales

    Författare :Anders Nyholm; Jesper Sollerman; Peter Lundqvist; Philip James; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supernovae; circumstellar medium; SNe Type IIn; iPTF13z; intermediate Palomar Transient Factory; active galactic nuclei; SN 2014J; Astronomy; astronomi;

    Sammanfattning : Some stars cease to be in a bright and destructive display called a supernova. This thesis explores what we can learn about supernovae (SNe) by studying their immediate surroundings, and what the SNe can teach us about their environments. LÄS MER

  7. 10. Quantification of pulmonary scintigraphy

    Författare :Jiahua Xu; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Emphysema; Inhomogeneity; Perfusion; scintigraphy; SPECT; 99mTc-Technegas; Ventilation; V Q;

    Sammanfattning : Modern nuclear medicine techniques, such as SPECT (single photon emission computed tomography), enable quantification and localisation of lung function in small lung elements, but appropriate methods are not yet available. The aim of the present project was therefore to develop and evaluate methods for mapping lung function in planar scintigrams and in SPECT. LÄS MER
