  1. 21. On Noise Generation and Dynamic Transmission Error of Gears

    Författare :Mats Henriksson; Leping Feng; Reader Andy Moorhouse; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik; Acoustics; Akustik;

    Sammanfattning : Noise from heavy trucks is an important environmental issue. Several sources contribute to the total noise level of a vehicle, such as the engine, gearbox, tires, etc. The tonal noise from the gearbox can be very disturbing for the driver, even if the noise level from the gearbox is lower than the total noise level.

  3. 22. Geometry of numbers, class group statistics and free path lengths

    Författare :Samuel Holmin; Pär Kurlberg; Yiannis Petridis; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geometry of numbers; lattices; class numbers; class groups; free path lengths; Mathematics; Matematik;

    Sammanfattning : This thesis contains four papers, where the first two are in the area of geometry of numbers, the third is about class group statistics and the fourth is about free path lengths. A general theme throughout the thesis is lattice points and convex bodies. LÄS MER

  4. 23. An Operatic Game Changer : The Opera Maker as Game Designer and the Potentials of Ludo-Immersive Opera

    Författare :Hedvig Jalhed; John Potter; Mälardalens universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; artistic research; opera; interaction; immersion; performance; perception; game design; participation; spectatorship; aesthetics; Apollonian; Dionysian;

    Sammanfattning : How can live-performed chamber operas be conceptualized as immersive gameswith interactive features? This artistic study has resulted in a system model throughwhich degrees of immersion may be generated and analyzed from physical, social,and psychical stimuli. A differentiation of immersive modes has been made possi-ble by the framing of opera-making as game design. LÄS MER

  5. 24. Magnetooptical properties of dilute nitride nanowires

    Författare :Mattias Jansson; Irina A Buyanova; Weimin Chen; Jan Eric Stehr; Hannah Joyce; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nanostructured III-V semiconductors have emerged as one of the most promising materials systems for future optoelectronic applications. While planar III-V compounds are already at the center of the ongoing lighting revolution, where older light sources are replaced by modern white light LEDs, fabricating such materials in novel architectures, such as nanowires and quantum dots, creates new possibilities for optoelectronic applications.

  7. 25. Small-Small : Moral Economy and the Marketspace in Northern Ghana

    Författare :Ulrik Jennische; Christina Garsten; Johan Lindquist; Sten Hagberg; Dinah Rajak; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ghana; small-scale trade; moral economy; informality; space and place; citizenship; socialantropologi; Social Anthropology;

    Sammanfattning : Over the past decade, the Ghanaian government has tried to include and accommodate the many people working in the so-called informal economy. This formalization process is in line with a global market-driven development discourse. LÄS MER
