  1. 16. Prerequisites for Efficient Programming of RFID Inlays in Reactive Near Field

    Författare :Markus Frank; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FOM; RNF; RFID; UHF.; Source Impedance Shift; DTLL; Phase compensation;

    Sammanfattning : The electromagnetically isolated programming of unique user IDs, into the transponder memory of UHF RFID inlays, is essential for successful operation in the RFID inventory process. Bar code printers enabled for RFID represent a typical environment of such programming. LÄS MER

  3. 17. Spatially Coupled Turbo-Like Codes

    Författare :Saeedeh Moloudi; Kommunikationsteknologi; []
    Nyckelord :;

    Sammanfattning : The focus of this thesis is on proposing and analyzing a powerful class of codes on graphs---with trellis constraints---that can simultaneously approach capacity and achieve very low error floor. In particular, we propose the concept of spatial coupling for turbo-like code (SC-TC) ensembles and investigate the impact of coupling on the performance of these codes. LÄS MER

  4. 18. Efficient Quantum Memories Based on Spectral Engineering of Rare-Earth-Ion-Doped Solids

    Författare :Mahmood Sabooni; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2013:Sabooni;

    Sammanfattning : The main aim of the present thesis is to demonstrate the efficient quantum memories for light employing coherent processes in rare-earth-ion-doped crystals. Rare-earth (RE) ions between lanthanum, with atomic number 57, and lutetium, with atomic number 71, have a partly filled 4f shell, which is spatially inside the full shells 5s, 5p, and 6s. LÄS MER

  5. 19. On the Relative Utility of 3D Interfaces

    Författare :Monica Tavanti; Mats Lind; Antonio Rizzo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Människa-dator-interaktion; human-computer interaction; information visualization; 2D and 3D interfaces; Människa-dator-interaktion; Information technology; Informationsteknologi; datavetenskap med inriktning människa-dator interaktion; Computer Science; human-computer interaction;

    Sammanfattning : Three-dimensional (3D) interfaces are made with the ambition to reinvent traditional two-dimensional (2D) displays into intuitive 3D environments that allow natural interactions and guarantee users’ satisfaction. However, reality is far from the expectations and 3D interfaces remain experimental. LÄS MER

  7. 20. Mechanistic modelling - a BOLD response to the fMRI information loss problem

    Författare :Karin Lundengård; Maria Engström; Gunnar Cedersund; Fredrik Elinder; Susanna Walter; Kâmil Uludağ; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Functional Magnetic Resonance Imaging (fMRI) is a common technique for imaging brain activity in humans. However, the fMRI signal stems from local changes in oxygen level rather than from neuronal excitation. LÄS MER
