  1. 6. Computer assisted evaluation of gas sensors : theory and applications

    Författare :Dennis Söderberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The application of a low cost computer as program control in a laboratory experimental situation is valuable for the evaluation of a complex measurement problem. The first step in a computer assisted evaluation is to design the experimental methods and construct the apparatus. LÄS MER

  3. 7. Light from Dark Matter : Hidden Dimensions, Supersymmetry, and Inert Higgs

    Författare :Michael Gustafsson; Lars Bergström; Steen Hannestad; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Recent observational achievements within cosmology and astrophysics have lead to a concordance model in which the energy content in our Universe is dominated by presumably fundamentally new and exotic ingredients – dark energy and dark matter. To reveal the nature of these ingredients is one of the greatest challenges in physics. LÄS MER

  4. 8. The asthmatic airway response – effects on physiology and biomarkers

    Författare :Henning Stenberg; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :Asthma; Exhaled breath temperature; Exercise; Allergen challenge; Small airways; Airway provocations; Spirometry; Impulse oscillometry; Inert gas washout; Body plethysmography; Club cell protein CC16 ;

    Sammanfattning : Asthma is a common airway inflammatory disease, associated with a variable degree of airway obstruction. It is a heterogeneous condition with large variations in severity and clinical presentation. Moreover, disease activity can vary from time to time. Taken together, these factors make the diagnosis, monitoring and treatment of asthma challenging. LÄS MER

  5. 9. Diluted Operation of a Heavy-Duty Natural Gas Engine - Aiming at Improved Effciency, Emission and Maximum Load

    Författare :Mehrzad Kaiadi; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; Natural gas engine; Dilution limit; VGT; Cyclic variation; Closed-loop control; Heavy-duty;

    Sammanfattning : Most heavy-duty engines are diesel operated. Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels.

  7. 10. Gas Flow And Chemical Reactions In Submicron Channels

    Författare :Petronella Norberg; Michael Bowker; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Through micromachining, it has become possible to realize mechanical structures of small dimensions with high reproducibility. There are numerous fields of application for such devices. The miniaturised structures have not only been used to improve existing techniques, but they have provided us with totally new possibilities. LÄS MER
