  1. 1. Searching for Gamma Rays from Galaxy Clusters with the Fermi Large Area Telescope : Cosmic Rays and Dark Matter

    Författare :Stephan Zimmer; Jan Conrad; Christophe Clement; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; galaxy clusters; gamma rays; cosmic rays; dark matter; fermi-lat; likelihood analysis; joint likelihood;

    Sammanfattning : In this licentiate thesis, I report a search for GeV γ rays towards the location of Galaxy clusters. I mainly discuss the results of a search for cosmic-ray (CR) induced γ-ray emission but also briefly elaborate on a related study, searching for Dark Matter (DM)-induced γ-ray emission from Galaxy clusters.

  4. 3. Joint Source-Channel Coding using Trellis Coded CPM

    Författare :Zihuai Lin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iterative decoding; serially concatenated CPM; punctured ring convolutional codes.; trellis coded quantization; turbo codes; turbo trellis coded modulation; soft decoding; ring convolutional coded CPM; continuous phase modulation; Joint source channel coding;

    Sammanfattning : The thesis investigates Joint Source and Channel Coding(JSCC) using combined Trellis Coded Quantization (TCQ) and coded modulation. First we investigate a JSCC scheme using combined TCQ/Trellis Coded CPM (TCQ/TCCPM). Based on the BCJR algorithm for trellis coded CPM, we derive an optimal soft decoding algorithm for the considered systems. LÄS MER

  5. 4. Temporomandibular disorders in women—symptoms and signs in population-based studies

    Sammanfattning : The overall aim of this thesis was to investigate symptoms and signs of temporomandibular disorders (TMD) and orofacial pain in the Swedish female population in relation to some other health factors. The thesis includes four cross-sectional studies. LÄS MER

  7. 5. Joint destruction in rheumatoid arthritis : experimental, clinical and epidemiological studies

    Författare :Rüdiger J Weiss; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Rheumatoid arthritis (RA) is a common autoimmune disease characterized by chronic polyarticular synovial inflammation. Erosive joint destruction represents a major unsolved complication of RA. Objectives: The aim of this thesis was to obtain increased knowledge of joint destruction by using a multidisciplinary approach. LÄS MER
