  1. 21. Modelling optical properties of morphologically complex soot aerosols

    Författare :Franz Kanngiesser; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aerosol; remote sensing; depolarisation; lidar; black carbon; scattering;

    Sammanfattning : Soot containing aerosol has both adverse impacts on the Earth's climate and on human health. Monitoring soot sources, transport pathways and sinks on global scale requires satellite-borne remote sensing techniques. LÄS MER

  3. 22. Characterization and forecasting of wind conditions over the Baltic Sea

    Författare :Christoffer Hallgren; Erik Sahlée; Julie Lundquist; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; forecasting; low-level jet; lidar; machine learning; mesoscale meteorology; numerical weather prediction; post-processing; reanalysis; sea breeze; turbulence; wind atlas; wind energy; wind power; Meteorologi; Meteorology;

    Sammanfattning : To meet the increasing demand of sustainably produced electricity, the total number of installed wind turbines is rapidly increasing globally. Although onshore installations are dominating, offshore wind power is taking a greater share of the market every year. LÄS MER

  4. 23. Towards Quantitative Diagnostics using Short-Pulse Laser Techniques

    Författare :Andreas Ehn; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PicoSecond Laser Diagnostics; Raman Scattering; Photo Fragmentation; Fluorescnece Lifetime Imaging; Temporal Filtering; Fysicumarkivet A:2012:Ehn; LIDAR; Laser-Induced Fluorescence;

    Sammanfattning : Laser based diagnostic tools have had an exploding impact on fundamental as well as applied research in a number of disciplines, such as biomedicine, physical chemistry etc over the last decades. Whereas fundamental research often investigate phenomena in extreme conditions, applied research aims at performing in-situ measurements, in order to understand the many aspects and entangled phenomena that affects the research of interest.

  5. 24. Non-Invasive Monitoring of Architectural Heritage

    Författare :Jenny Hällström; Bebyggelsevård; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing; lidar; laser-induced fluorescence; documentation; hyperspectral; non invasive; non destructive; sustainable maintenance; conservation planning; monitoring; Coliseum; architectural conservation; restoration; Övedskloster; deterioration; Lateran Baptistery; stone; brick; thematic mapping; in situ; imaging; biodeteriogens;

    Sammanfattning : The on-site documentation and examination of architectural heritage has presented challenges for traditional analysis methods in the form of, among other things, large complex structures, sites and environmental conditions. In recent years there has been growing interest in assessing progressing deterioration processes and material analysis, with an emphasis on sustainable conservation and maintenance planning. LÄS MER

  7. 25. Application of Laser Techniques for Combustion Studies

    Författare :Marcus Aldén; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Keywords: Laser-induced fluorescence; Raman Spectroscopy; Coherent anti-Stokes Raman Scattering CARS ; flames; laserspectroscopy; dye laser; lidar; remote sensing; combustion; air pollution; radicals; optical multichannel analyzer.; Fysicumarkivet A:1983:Aldén;

    Sammanfattning : The aim for this work has been to increase the applicability of laser spectroscopy techniques for studies of combustion processes, both what regards in-flame experiments, exhaust-gas analysis and remote sensing of the atmosphere. Raman spectroscopy has been used for analysis of exhaust gases from flames, model fires of wood and for inflame measurements. LÄS MER
