  2. 1. Surface Status Classification, Utilizing Image Sensor Technology and Computer Models

    Author : Patrik Jonsson; Hans-Erik Nilsson; Benny Thörnberg; Jörgen Bogren; Torbjörn Eltoft; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road condition; NIR; infrared; remote sensing; signal processing; classifiers;

    Abstract : There is a great need to develop systems that can continuously provide correct information about road surface status depending on the prevailing weather conditions. This will minimize accidents and optimize transportation. READ MORE

  4. 2. Retrieval of ocean surface winds and currents using satellite synthetic aperture radar and infrared radiometry

    Author : Gisela Carvajal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface currents; infrared radiometry; synthetic aperture radar; surface winds; maximum cross correlation; wind direction;

    Abstract : This thesis focuses on the development, analysis and evaluation of methods for the retrieval of ocean surface winds with synthetic aperture radar (SAR) and surface currents with infrared (IR) radiometer sensors. The SAR wind speed retrievals are based on geophysical model functions using wind directions obtained with two approaches. READ MORE

  5. 3. Advancement of sensor technology for monitoring and control of upstream bioprocesses

    Author : Judit Randek; Carl-Fredrik Mandenius; Gerald Striedner; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In bioprocesses, the upstream process part with cultivation and harvesting steps has decisive influence on the final process outcome, including the quality of the product, the productivity and the yield. To ensure stable product quality of biopharmaceuticals, the U.S. READ MORE

  6. 4. Quantitative laser diagnostics of gas-phase potassium species in biomass combustion and gasification

    Author : Emil Thorin; Florian Schmidt; Markus Broström; Zhongshan Li; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical conversion; pyrolysis; phosphorus; single pellet; entrained-flow; in situ; spectroscopy; photofragmentation; imaging; numerical modelling; fysik; Physics;

    Abstract : Thermochemical energy conversion processes, such as combustion and gasification, are applied worldwide for generation of electricity, heat and synthesis of chemicals. Today, these processes are mostly run on non-renewable, fossil fuels and constitute a major source of carbon dioxide emissions. READ MORE

  7. 5. Hybrid Plasmonics for Energy Harvesting and Sensing of Radiation and Heat

    Author : Mina Shiran Chaharsoughi; Magnus Jonsson; Xavier Crispin; Simone Fabiano; Eunkyoung Kim; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The special optical properties of subwavelength metallic structures have opened up for numerous applications in different fields. The interaction of light with metal nanostructures leads to the excitation of collective oscillations of conduction-band electrons, known as plasmons. READ MORE
