  • Characterisation and modelling of loudspeaker cone resonance

    Taberner, Andrew James (The University of Waikato, 1998)
    Loudspeaker cone resonance (“cone break-up”) is a fundamental cause of ripple in the electrical impedance and sound pressure responses of electrodynamic loudspeakers. In this thesis, the dependence of the characteristics ...

  • Quantification of respiratory sinus arrhythmia by use of low order ARX models

    Han, Bo (The University of Waikato, 1999)
    Respiratory Sinus Arrhythmia (RSA) is a change in the heart rate that corresponds to the frequency of respiration, but its causative mechanisms in humans remain only partially determined. In this thesis, models of the human ...

  • Modelling the anaestheto-dynamic phase transition of the cerebral cortex

    Steyn-Ross, D. Alistair (The University of Waikato, 2002)
    This thesis examines a stochastic model for the electrical behaviour of the cerebral cortex under the influence of a general anaesthetic agent. The modelling element is the macrocolumn, an organized assembly of ∼10⁵ ...

  • Three-dimensional biomechanical analysis of fast bowling in cricket

    Ferdinands, R. E. D. (The University of Waikato, 2003)
    A three-dimensional (3-D) dynamics model of the human body has been developed to provide a mechanical basis for evaluating fast bowling technique. Thirty-four fast bowlers were selected for study and divided into four ...

  • 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 ...
