  • The Art of Coffee Roasting: Investigations into Sensor Development for the Application of Controlling Coffee Roasting

    Kelly, Cameron Brian Desmond (The University of Waikato, 2018)
    In this thesis, I investigate novel methods of sensing change in roasting coffee. Coffee roasting is a vital step in coffee’s supply chain. It is the process that takes green coffee and transforms it via a series of many ...
  • 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 ...
  • Surface Roughening of Platinum Wire: An Electrochemical and Mechanical Approach

    Gygax, Stefan Manu (University of Waikato, 2017)
    In order to make implanted electrodes MRI safe several methods have been explored. One of those methods involves increasing AC resistance by roughening the surface of the implanted platinum wires. This thesis explores an ...
  • The Electrical Properties of Interfacial Double Layers

    Jones, Mark Hedley (University of Waikato, 2016)
    When solids and liquids are brought together, interfacial double-layers are likely to form. They are too small to feel or see so their presence goes mostly unnoticed at the macroscopic level. A double layer is essentially ...
  • Scaling acoustic directional couplers using 3D printing

    MacDonell, Marcus Scott Glengarry (University of Waikato, 2015)
    Acoustic directional couplers permit separation of forward and reverse sound pressure waves. This separation opens the way to traceable, precision acoustic reflection measurements. In order to span the audio spectrum, ...
