    • Consequences of port mismatch and finite isolation on power combining 

      Eccleston, K.W. (University of Canterbury. Electrical and Computer Engineering, 1994)
      In solid-state power amplification, power combining is an important issue since the output powers from individual transistors are too small for many transmission applications. An important aspect of power combining is ...
    • Technology assessment of landfill leachate treatment by evaporation 

      Milke, M. (University of Canterbury. Civil and Natural Resources Engineering, 1995)
      Leachate treatment by evaporation is beginning to be applied in Europe. The technology allows around 95% removal of COD, ammonia, and metals. The success of its application to landfill leachate depends upon the pH of ...
    • The potential use of heat flux to infer landfill gas flux 

      Milke, M.W.; Simpson, N.J. (University of Canterbury. Civil and Natural Resources Engineering, 1996)
      An assessment is made of how heat flux might be used to infer gas fluxes from municipal solid waste landfills. Thermodynamic principles are used to estimate the amount of heat generated per mole of anaerobically-produced ...
    • Spatio-Temporal Filtering of the EEG via Neural Network Based Multireference Adaptive Noise Cancelling 

      James, C.J.; Hagen, M.T.; Jones, R.D.; Bones, P.J.; Carroll, G.J. (University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Communication Disorders, 1996)
      A system is proposed which enhances transient nonstationarities and, in particular, epileptiform discharges in the EEG. It is based around the technique of multireference adaptive noise cancelling (MRANC) which attenuates ...
    • The Self-Organising Feature Map in the Detection of Epileptiform Transients in the EEG 

      James, C.J.; Jones, R.D.; Bones, P.J.; Carroll, G.J. (University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Communication Disorders, 1996)
      A system is proposed which utilises Kohonen’s selforganising feature map (SOFM) to help detect the presence of epileptiform transients in the EEG. The system consists of a feature extractor, which employs a mimetic approach ...
    • Within a context: the benefits of teaching introductory environmental engineering with a detailed case study 

      Milke, M.W. (University of Canterbury. Civil and Natural Resources Engineering, 1996)
      The teaching of introductory environmental engineering can easily lead to students complaining that they are receiving too much broad, general instruction. Engineering students, more than liberal arts students, often require ...
