    Abstract : Increasingly intensive efforts are being made to enhance energy systems via augmented introduction of renewable energy along with improved energy efficiency. Resource constraints and sustained high fossil fuel prices have created a new phenomenon in the world market. READ MORE

  5. 3. Experimental Investigation of Three-Dimensional Single and Double optical Lattices

    Author : Harald Ellmann; Poul Jessen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A complete laser cooling setup was built, with focus on threedimensional near-resonant optical lattices for cesium. These consist of regularly ordered micropotentials, created by the interference of four laser beams. One key feature of optical lattices is an inherent ”Sisyphus cooling” process. READ MORE

  6. 4. Performance of Energy Efficient Windows and Solar Shading Devices

    Author : Tobias Rosencrantz; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This Licentiate dissertation deals with windows and solar shading devices and how they could be designed and used to save energy for heating and cooling in buildings. Parametric studies using the dynamic energy simulation software ParaSol v 2.0 were performed for different windows and solar shading devices. READ MORE

  7. 5. Physical modeling of on-state losses in bipolar Si and SiC power devices

    Author : Olof Tornblad; KTH; []
    Keywords : ;

    Abstract : Power losses affect both the installation- and long-term cost of power electronic systems. The installation cost is related to the fatt that power losses in silicon power devices generate heat and make installation of heat sinks and water cooling necessary. If self-heating effects are strong, lotal overheating can eventually lead to device failure. READ MORE
