  • Acoustic Vector Network Analyser

    Pennington, Kyle (The University of Waikato, 2017)
    This research aims at increasing the accuracy and precision of characterising acoustic materials by adapting well-known techniques developed for the radio-frequency domain to the acoustic domain. Two novel methods are ...
  • Supecapacitor-assisted Temperature Modification Apparatus (SCATMA) and Fast Supercapacitor Charger

    Gurusinghe, Nicoloy (University of Waikato, 2016)
    This thesis presents the design and development of the supercapacitor-assisted "instant" water heating system as well as a new power converter topology to fast charge a supercapacitor bank. Delayed delivery of hot water ...
  • Analysis on Supercapacitor Assisted Low Dropout (SCALDO) Regulators

    Gunawardane, Kalpani Kosala (University of Waikato, 2014)
    State-of-the-art electronic systems employ three fundamental techniques for DC-DC converters: (a) switch-mode power supplies (SMPS); (b) linear power supplies; (c) switched capacitor (charge pump) converters. In practical ...
  • Optimizing Compton camera performance

    Uche, Chibueze Zimuzo (University of Waikato, 2011)
    Amore realistic simulation approach is used to study the behavior of the Compton camera in this thesis than previous studies to date. The Compton camera differs from gamma cameras in that the collimator is replaced by a ...
  • Fast Monte Carlo Simulation of ⁹⁰Y Bremsstrahlung using a Kernel-based Photon Source

    Zakariah, Suhaili (University of Waikato, 2011)
    In targeted radionuclide therapy using ⁹⁰Y, bremsstrahlung photons can be used for imaging and subsequently for absorbed dose estimation. Monte Carlo simulation is a reliable method to study bremsstrahlung imaging but it ...
