  1. 21. Topics in Dynamic Spectrum Access : Market Based Spectrum Sharing and Secondary User Access in Radar Bands

    Author : Miurel Tercero Vargas; Jens Zander; Mikael Prytz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; spectrum sharing; radar band; cognitive radio; Telecommunication; Telekommunikation; Systems engineering; Systemteknik;

    Abstract : The steady growth in demand for spectrum has increased research interest in dynamic spectrum access schemes. This thesis studies some challenges in dynamic spectrum access based on two strategies: open sharing and hierarchical access. READ MORE

  2. 22. Wind Power and Natural Disasters

    Author : Jon Olauson; Mikael Bergkvist; Stefan Ivanell; Uppsala universitet; []
    Keywords : Wind power; Natural disasters; Hybrid energy system; Meteorological model; Statistical model; Variability; Wind power integration;

    Abstract : Wind power can be related to natural disasters in several ways. This licentiate thesis gives some background and introduces four papers devoted to two aspects of this relation. The first section looks into how small-scale wind energy converters (WECs) could be used to generate power after a natural disaster. READ MORE

  3. 23. Climate Related Thermal Actions for Reliable Design of Concrete Structures

    Author : Oskar Larsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal stress; solar radiation; FE-analysis; climate data; box-girder bridge; KstrConcrete; KstrReliability;

    Abstract : When the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. READ MORE

  4. 24. Seasonal aspects of peripartum depressive symptoms

    Author : Hanna E. Henriksson; Alkistis Skalkidou; Fotios Papadopoulos; Sara M Sylvén; Stavros I Iliadis; Lauren M. Osborne; Uppsala universitet; []
    Keywords : peripartum depressive symptoms; pregnancy; postpartum; seasonality; meteorological parameters; inflammatory markers; proximity extension assay; metabolomics; gas chromatography-mass spectrometry;

    Abstract : Every year, a large proportion of pregnant and newly delivered women develop peripartum depression, a condition that may cause long-term suffering for the entire family. Although there is a lack of consensus, some studies propose an association between season and the risk of developing depression during pregnancy and the postpartum period. READ MORE

  5. 25. Modelling Wind Power for Grid Integration Studies

    Author : Jon Olauson; Mikael Bergkvist; Mats Leijon; Thomas Hamacher; Uppsala universitet; []
    Keywords : Wind power; Wind power modelling; Intermittent renewables; Variability; Integration or renewables; Reanalysis data; Power system studies;

    Abstract : When wind power and other intermittent renewable energy (IRE) sources begin to supply a significant part of the load, concerns are often raised about the inherent intermittency and unpredictability of these sources. In order to study the impact from higher IRE penetration levels on the power system, integration studies are regularly performed. READ MORE
