  1. 1. Essays on Credit Risk

    Författare :Caren Guo Nielsen; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Asset pricing; equity returns; size effect; value effect; momentum effect; credit risk effect; credit default swap; banks; asset risk; credit risk; portfolio choice; risk-based capital regulation; bank bailouts; moral hazard; distress risk; capital injections; TARP; CPP; market discipline; financial crisis;

    Sammanfattning : This dissertation covers the issues related to credit risk that stem from the recent financial crisis and that are concerned by investors, financial intermediaries, and governments. The results of the research have important implications for asset managers, such as using the information from the credit risk market to rebalance stock portfolios, and for policy makers in regulating or bailing out banks.

  2. 2. The mechanics in two nanosized systems : Size effect and threshold field

    Författare :Martin Olsen; Håkan Olin; Ulf Lindefelt; Sven Öberg; Mittuniversitetet; []
    Nyckelord :;

    Sammanfattning : This thesis investigates the mechanics in two nanosized system. Paper I investigates a size effect in a cantilever nanowire affecting its resonance frequency. Paper II reveals a threshold field for the formation of a mound by the diffusion of surface atoms on a substrate under a STM-tip. LÄS MER

  3. 3. Why and how brain size evolves : Sociality, predation and allometry

    Sammanfattning : The evolution of the vertebrate brain has remained a topic of intense interest from biologists over many decades. Evolutionary biologists have seen it as an intriguing example of how the size and structure of a trait evolves across large phylogenies and under body size constraints, with both large shifts in deep evolutionary time and continuous smaller scale adaptation.

  5. 5. Performance of high-frequency mechanical impact treatment for bridge application

    Författare :Poja Shams Hakimi; Chalmers University of Technology; []

    Sammanfattning : This thesis investigates the performance of high-frequency mechanical impact (HFMI) treatment for implementation on new bridge designs. Fatigue strength improvement with HFMI can enable lightweight design of bridges and allow the utilisation of the benefits of high-strength steels. LÄS MER
