  1. 11. Storyforming : Experiments in creating discursive engagements between people, things and environments

    Författare :Loove Broms; Sara Ilstedt Hjelm; Cecilia Katzeff; Johan Redström; Jonathan Chapman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interaction design; sustainable design; research through design; critical design; Machine Design; Maskinkonstruktion;

    Sammanfattning : This thesis introduces and critically reflects on a design programme, Storyforming, that explores ways to design objects and places to enrich daily life narratives. Using an experimental design approach, the goal is to exemplify and explore this idea with discursive artefacts that, through their physical and temporal form, act as catalysts in the construction of meaningful experiences.

  3. 12. On the performance of stratified ventilation

    Författare :Ulf Larsson; Bahram Moshfegh; Per Heiselberg; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : People nowadays spend most of their time indoors, for example in their homes, cars, in trains, at work, etc. In Sweden, the energy demand in the built environment is a growing issue. LÄS MER

  4. 13. Optical Diagnostics for Engine Efficiency in Gasoline Compression Ignition

    Författare :Miao Zhang; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPC; Optical engine; Engine Eciency; Multiple-injection strategies; Thermodynamic analysis;

    Sammanfattning : The internal combustion engine has played a significant role in a vast number of applications from small cars to giant tankers, setting people free from geographical barriers and heavy labor. However, it has also generated many tons of harmful emissions and CO2that damage to humans and the environment. LÄS MER

  5. 14. High Octane Number Fuels in Advanced Combustion Modes for Sustainable Transportation

    Författare :Amir Bin Aziz; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Octane number; Low temperature combustion LTC ; Ignition delay; Methanol; HCCI; PPC; Multiple injection strategy; φ-stratification;

    Sammanfattning : The research community recently proposed a low-temperature combustion (LTC) concept that can simultaneously reduce Nitrogen Oxides (NOx) and soot emissions while maintaining high engine efficiency. Given that diesel fuel is prone to preignition with early injection, gasoline-like fuel with high octane number is utilised to provide sufficient ignition delay and extend the load range. LÄS MER

  7. 15. Electromechanics of Vertical Axis Wind Turbines

    Författare :Morgan Rossander; Sandra Eriksson; Hans Bernhoff; Daniel Karlsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Diode rectification; Control; Measurement; Simulation; Electromechanical coupling; vindkraft; diodlikriktning; reglering; mätning; simulering; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Wind power is an established mean of clean energy production and the modern horizontal axis wind turbine has become a common sight. The need for maintenance is high and future wind turbines may need to be improved to enable more remote and offshore locations. LÄS MER
