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

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Författare :Klas Persson; Georgia Destouni; Aldo Fiori; [2011]
    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. 3. High-Temperature Microfluidics for Space Propulsion

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ville Lekholm; Klas Hjort; Anders Persson; Lena Klintberg; Herbert Shea; [2015]
    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

  4. 4. Homogenization of some elliptic equations with connections to elasticity

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Klas Pettersson; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; Matematik; Mathematics;

    Sammanfattning : In this PhD thesis we prove some properties of elliptic equations in connection with periodic homogenization. We mainly study the stationary linearized elasticity system. This thesis consists of five papers complemented with a short introduction.The first paper concerns some elliptic equations on a domain with oscillating boundary. LÄS MER
