  1. 1. Meta-Languages and Semantics for Equation-Based Modeling and Simulation

    Författare :David Broman; Peter Fritzson; Jeremy Siek; Thomas Schön; Björn Lisper; Walid Taha; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meta-language; semantics; EOO; Modelica; equations; modeling; simulation; MKL; Computer science; Datalogi;

    Sammanfattning : Performing computational experiments on mathematical models instead of building and testing physical prototypes can drastically reduce the develop cost for complex systems such as automobiles, aircraft, and powerplants. In the past three decades, a new category of equation-based modeling languages has appeared that is based on acausal and object-oriented modeling principles, enabling good reuse of models. LÄS MER

  3. 2. Air Pollution Dependency on Climate Variability and Source Region : Past, Current and Future Air Pollution Scenarios over Europe

    Författare :Camilla Andersson; Hans-Christen Hansson; Christer Johansson; Joakim Langner; David Simpson; Peter Builtjes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acidification; Air Pollution; Climate Change; Europe; Numerical Model; Emission; Eutrophication; Key region; Nitrogen Dioxide; Particulate Matter; PM; Source region; Surface Ozone; Tropospheric Ozone; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The main objectives of this thesis were to investigate the dependency of European air pollution on climate variability and emission source region. Calculations with a chemistry transport model (CTM) were conducted to investigate the influence of climate variability. LÄS MER

  4. 3. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities

    Författare :Daniela Guasconi; Gustaf Hugelius; Sara Cousins; Stefano Manzoni; Petra Fransson; David Johnson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil; soil carbon; soil ecology; roots; root traits; microbial communities; grasslands; climate change; drought; land management; compost; naturgeografi; Physical Geography;

    Sammanfattning : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. LÄS MER

  5. 4. Human papillomavirus in recurrent respiratory papillomatosis, tonsillar and mobile tongue cancer

    Författare :Christos Loizou; Katarina Olofsson; Karin Nylander; David Lindquist; Göran Laurell; Stina Syrjänen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human papillomavirus; recurrent respiratory papillomatosis tonsillar cancer; mobile tongue cancer; voice-; and quality of life; p16; syndecan-1; northern Sweden;

    Sammanfattning : This thesis focuses on the effects of the human papillomavirus (HPV) in tonsillar cancer, mobile tongue cancer, and recurrent respiratory papillomatosis (RRP). The purpose was to characterize patients with RRP in northern Sweden in order to identify more care-intensive RRP patients and to describe the voice and quality of life aspects that follow RRP.
