  1. 16. Arctic clouds - interactions with radiation and thermodynamic structure

    Författare :Joseph Sedlar; Michael Tjernström; Annica Ekman; Johannes Verlinde; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; stratus; radiation; thermodynamic structure; cloud radiative forcing; seasonal transition; Meteorology; Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : Clouds play in important role in the climate system through their interaction with radiation. Globally, clouds tend to cool the Earth by reflecting solar radiation and shading the surface. LÄS MER

  3. 17. Lifecycle of Black Carbon in the Arctic

    Författare :Roxana S. Cremer; Ilona Riipinen; Peter Tunved; Sara Blichner; Hannele Korhonen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Aerosols; Arctic; lifecyle; absorption; Environmental Sciences; miljövetenskap;

    Sammanfattning : This PhD thesis investigates the atmospheric life cycle of Black Carbon (BC) in the Arctic. The Arctic region has been rapidly changing in the last decades and the role of BC aerosols in this is still uncertain. LÄS MER

  4. 18. Fractionation of the stable silicon isotopes studied using MC-ICP-MS : analytical method developments and applications in geochemistry

    Författare :Emma Engström; Ben Reynolds; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : In spite of the high Si abundance in natural systems, expected significant mass-dependent fractionations, and the importance of the element in many areas of the Earth sciences (focusing on e.g. LÄS MER

  5. 19. Automatic Design-Space Exploration of Integrated Multi-Standard Wireless Radio Receivers

    Författare :Delia Rodríguez de Llera González; Mohammed Ismail; Hannu Tenhunen; Atila Alvandpour; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik;

    Sammanfattning : One of the main challenges posed by 4G wireless communication systems is achieving flexible, programmable multi-standard radio transceivers with maximum hardware share amongst different standards at a minimum power consumption. Evaluating the feasibility and performance of different multi-standard/multi-band radio solutions at an early stage, i.e. LÄS MER

  7. 20. A study of maintenance performance indicators for the Swedish railroad system

    Författare :Thomas Åhrén; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : The Swedish railway authorities have a long tradition of using performance indicators to follow up their performance. Already in 1915 when they decided to electrify the iron ore line between Kiruna and Riksgränsen, they introduced some indicators to measure and follow up expected benefits of upgrading the transportation system, e.g. LÄS MER
