  1. 6. Theoretical Investigation of a new OFDM Access-Network Topology (OTONES)

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Aditya Kakkar; [2013]
    Nyckelord :OTONES; SSB Method; Image Rejection; Novel Bedrosian Method; Orthogonal Frequency Division Multiplexing OFDM ; Optical Network Unit ONU ; Optical Line Terminal OLT ; Coherent Receiver; Remote Heterodyne Detection; Optical Access Network; WDM network;

    Sammanfattning : Recent studies on growth of telecomm sector depict an ever rising demand for high bandwidth applications such as on-line gaming, high definition television and many more. This demand is coupled with increase in internet connected utilities per house hold - each requiring a portion of bandwidth. LÄS MER

  3. 7. Prototype Development of an A-Mode Ultrasound Based Intrafraction Motion Management System

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Abebe Hailu; Fredrik Lundqvist; [2013]
    Nyckelord :Intrafraction motion management; A-mode ultrasound; stereotactic body radiation therapy; ultrasonic distance measurement; embedded system;

    Sammanfattning : Owing to the steep dose fall-off curves of high precision and accuracy radiation therapy (RT) modalities such as stereotactic body RT (SBRT), treatment plans with extraordinarily small margins to organs at risk (OARs), such as the spinal cord, has been made possible. With this development, patient movements during treatment, i.e. LÄS MER

  5. 9. Identification of cause of impairment in spiral drawings, using non-stationary feature extraction approach

    Master-uppsats, Datateknik

    Författare :Muhammad Usman Yaseen; [2012]
    Nyckelord :Parkinson’s Disease; Hilbert Huang Transform; Principle Component Analysis;

    Sammanfattning : Parkinson’s disease is a clinical syndrome manifesting with slowness and instability. As it is a progressive disease with varying symptoms, repeated assessments are necessary to determine the outcome of treatment changes in the patient. In the recent past, a computer-based method was developed to rate impairment in spiral drawings. LÄS MER

  7. 10. Demodulation Techniques in Gearbox Diagnostics

    Uppsats för yrkesexamina på grundnivå, Signaler och System

    Författare :Andreas Meisingseth; [2012]
    Nyckelord :Gearbox diagnostics; demodulation;

    Sammanfattning : This thesis covers the scope of one out of many ways to diagnose gearboxes, demodulating the excited vibrational signals to enhance fault detection and identification. The topic is not only of academic interest since the achievements that can be made by successful machine condition monitoring in the industry. LÄS MER
