  1. 1. Conceptual Thermodynamic Cycle and Aerodynamic Gas Turbine Design - on an Oxy-fuel Combined Cycle

    Författare :ADRIAN NILSSON DAHLQVIST; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; combined cycle; conceptual design; aerodynamic; mid-span design; through-flow design; oxy-fuel; SCOC-CC; OCC; gas turbine; Combined cycle; conceptual design; aerodynamic; mid-span design; Through-flow design; Oxy-fuel; SCOC-CC; OCC;

    Sammanfattning : The world is today facing a serious problem with global warming, which is heading towards an appallingly high temperature level. The greater part of the overall climate science community agree that global warming is caused by the greenhouse effect, which depends largely on emitted CO2 emissions from the combustion of fossil fuel.

  3. 2. Maintaining data consistency in embedded databases for vehicular systems

    Författare :Thomas Gustafsson; Jörgen Hansson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Engine control software; real-time; embedded applications; metainformation; algorithms; Performance evaluations; HP2PL; OCC; Computer science; Datavetenskap;

    Sammanfattning : The amount of data handled by real-time and embedded applications is increasing. This calls for data-centric approaches when designing embedded systems, where data and its metainformation (e.g., temporal correctness requirements) are stored centrally. LÄS MER

  4. 3. On Toxicant-Induced Succession in Periphyton Communities: Effects of Single Chemicals and Chemical Mixtures

    Författare :Tobias Porsbring; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; community ecotoxicology; toxicant-induced succession; chemical mixtures; concentration addition; independent action; diatoms; periphyton; algal pigments; algal sterols;

    Sammanfattning : This thesis deals with the effects of single chemicals and chemical mixtures on biological communities. Ecosystems are exposed to complex mixtures of chemicals, and because combination effects can occ... LÄS MER

  5. 4. The Friction between Paper Surfaces

    Författare :Niklas Garoff; KTH; []
    Nyckelord :friction; fibers; boundary lubrication; adhesion; capillary condensation; surface forces; chemcial analysis; x-ray photoelectron spectroscopy; atomic force microscope;

    Sammanfattning : The main objective for the work described in this PhD thesiswas to formulate a friction model to characterize thefrictional behavior of paper. More specifically, the modelshould explain a phenomenon that is typical for paper grades,viz.: that the level of paper-to-paper friction is dependent onthe direction and the number of previous slides.
