  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. Development and Application of Laser Diagnostics for Studies of Phenomena Related to IC Engine Combustion

    Författare :Greger Juhlin; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Motors and propulsion systems; framdrivningssystem; Motorer; Laser technology; Laserteknik; Fysicumarkivet A:2003:Juhlin;

    Sammanfattning : Various laser diagnostic techniques have been developed and demonstrated for engine, or engine-related measurements. The experimental work is presented in Chapter 3 and in Papers I-VII. In Chapter 3, imaging of soot in a running compression-ignition (CI) is described. LÄS MER

  4. 3. Local Conditions for Long Cycles in Graphs

    Författare :Jonas B. Granholm; Carl Johan Casselgren; Armen Asratian; Jørgen Bang-Jensen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A Hamilton cycle in a graph is a cycle that passes through every vertex of the graph. A graph is called Hamiltonian if it contains such a cycle. The problem of determining if a graph is Hamiltonian has been studied extensively, and there are many known sufficient conditions both for Hamiltonicity and for other, related properties. LÄS MER

  5. 4. Studies on bikeability in a metropolitan area using the active commuting route environment scale (ACRES)

    Författare :Lina Wahlgren; Peter Schantz; Henrik Gustafsson; Pekka Oja; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; active transport; bicycle commuting; bikeability; multiple linear regression analysis; perception; reliability; route environment; validity; Sports; Idrott; Sports Science; Idrottsvetenskap; Samhällsvetenskap Humaniora;

    Sammanfattning : Background: The Active Commuting Route Environment Scale (ACRES) was developed to study active commuters’ perceptions of their route environments. The overall aims were to assess the measuring properties of the ACRES and study active bicycle commuters’ perceptions of their commuting route environments. LÄS MER

  7. 5. Closed-Loop Control of HCCI Engine Dynamics

    Författare :Johan Bengtsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Sammanfattning : The topic of the thesis is control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics. HCCI offers a potential to combine high efficiency with very low emissions. In order to fulfill the potential benefits, closed-loop control is needed. LÄS MER
