  2. 21. Optical Design for Stationary Solar Concentrators

    Author : Johan Nilsson; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photovoltaic cells; parabolic reflectors; optical efficiency; Solar concentrators; photovoltaic-thermal systems; non-imaging optics; optical properties; building integrated photovoltaics; non uniform irradiance distribution; structured reflectors; solar cell modelling; ray tracing;

    Abstract : Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. READ MORE

  6. 24. Gameplay (3D Game Engine + Ray Tracing = Visual Attention through Eye Tracking)

    Author : Charlotte Sennersten; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Spelutveckling; Game development; Cognition; Vision; Gameplay; Instrumentation; 3D Game Engine; Eyegaze tracking;

    Abstract : Research into gameplay can contribute to more self-conscious approaches to design, allowing designers to create effective gameplay with less testing, or to target specific cognitive and emotional affects of gameplay for serious games applications. Self-conscious design includes theoretically motivated design of game systems to facilitate gameplay motivated by cognitive, scientific and/or rhetorical theories of game affect and functionality.

  7. 25. A Stacked Prism Lens Concept for Next-Generation Hard X-Ray Telescopes

    Author : Wujun Mi; Mats Danielsson; Peter Nillius; Ralf K. Heilmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; focusing X-ray telescopes; Wolter-I optics; stacked prism lens; focused UV lithography; grayscale e-beam lithography; proximity effect correction; angular resolution; effective collecting area; röntgenteleskop; Wolter-I-optik; staplade prismalinser; fokuserad UV-litografi; elektronstråle-litografi; Fysik; Physics;

    Abstract : Over the past half century, the focusing X-ray telescope has played a very prominent role in X-ray astronomy at the frontier of fundamental physics. The finer angular resolution and increased effective area have enabled more and more exciting discoveries and detailed studies of the high-energy universe, including the cosmic X-ray background (CXB) radiation, black holes in active galactic nuclei (AGN), galaxy clusters, supernova remnants, and so on.
