  1. 11. Symmetries of the Point Particle

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Alexander Söderberg; [2014]
    Nyckelord :symmetries; spin; classical physics; classical field theory; action; smooth spinning particle; pauli-lubanski; noether; theorem; poincare group; lorentz group; galilean transformations; relativistic; equations of motion; boost; rotation; translation; quantization; bosonic string; rigid particle; momentum; momenta; generators;

    Sammanfattning : We study point particles to illustrate the various symmetries such as the Poincaré group and its non-relativistic version. In order to find the Noether charges and the Noether currents, which are conserved under physical symmetries, we study Noether’s theorem. LÄS MER

  3. 12. The perceptual impact of different quantization schemes in G.719

    Master-uppsats, KTH/Kommunikationsteori

    Författare :Bote Liu; [2013]
    Nyckelord :;

    Sammanfattning : In this thesis, three kinds of quantization schemes, Fast Lattice Vector Quantization (FLVQ), Pyramidal Vector Quantization (PVQ) and Scalar Quantization (SQ) are studied in the framework of audio codec G.719. FLVQ is composed of an RE8 -based low-rate lattice vector quantizer and a D8 -based high-rate lattice vector quantizer. LÄS MER

  4. 13. Geometry of BV Quantization and Mathai-Quillen Formalism

    Magister-uppsats, Teoretisk fysik

    Författare :Luigi Tizzano; [2013]
    Nyckelord :;

    Sammanfattning : Mathai-Quillen (MQ) formalism is a prescription to construct a Gaussian shaped Thom form for a vector bundle. The aim of this master thesis is to formulate a new Thom form representative using geometrical aspects of Batalin-Vilkovisky (BV) quantization. LÄS MER

  5. 14. Benchmark of MPEG-2 Video Decoding on ePUMA Multi-core DSP Processor

    Master-uppsats, Datorteknik

    Författare :Peng Xiaoyi; [2011]
    Nyckelord :;

    Sammanfattning : Video decoding technologies have been widely used in our daily life. Higherresolutions and more advanced coding technologies may promote the capabilitiesof video decoding. LÄS MER

  7. 15. Color Segmentation using LVQ-Learning Vector Quantization

    Master-uppsats, Datateknik

    Författare :Hussain Jabbar; [2010]
    Nyckelord :Color; RGB; HSV; Hue; Saturation; Pixel; Matrix; MATLAB; LVQ.;

    Sammanfattning : This thesis aims to present a color segmentation approach for traffic sign recognition based on LVQ neural networks. The RGB images were converted into HSV color space, and segmented using LVQ depending on the hue and saturation values of each pixel in the HSV color space. LÄS MER
