  1. 1. Quantifying pollutant spreading and the risk of water pollution in hydrological catchments : A solute travel time-based scenario approach

    Författare :Klas Persson; Georgia Destouni; Aldo Fiori; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water pollution; catchment; pollution risk; scenario analysis; uncertainty; Physical Geography; naturgeografi;

    Sammanfattning : The research presented in the thesis develops an approach for the estimation and mapping of pollutant spreading in catchments and the associated uncertainty and risk of pollution. The first step in the approach is the quantification and mapping of statistical and geographical distributions of advective solute travel times from pollutant input locations to downstream recipients.

  3. 2. Visual Odometryin Principle and Practice

    Författare :Mikael Persson; Michael Felsberg; Klas Nordberg; Per-Erik Forssén; Janne Heikkilä; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Visual Odometry; Continuous Pose Trajectory; P3P; PNP; VO; Tracking; Calibration;

    Sammanfattning : Vision is the primary means by which we know where we are, what is nearby, and how we are moving. The corresponding computer-vision task is the simultaneous mapping of the surroundings and the localization of the camera. This goes by many names of which this thesis uses Visual Odometry. LÄS MER

  5. 4. High-Temperature Microfluidics for Space Propulsion

    Författare :Ville Lekholm; Klas Hjort; Anders Persson; Lena Klintberg; Herbert Shea; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : In this thesis, microfabrication methods and tools for analysis of heated cold-gas microthrusters are presented, with the aim of improving their reliability and performance. Cold-gas thrusters operate by accelerating pressurized gas through a nozzle. LÄS MER
