    • Valuation of harmonic current injections 

      Talacek, Philip (University of Canterbury. Electrical & Computer Engineering, 2002)
      The number of power electronic and distorting loads, continue to grow at a rapid pace. Accompanying this growth in distortion sources is an increased sensitivity of certain types of loads to harmonic distortion, and poor ...
    • Valuing Breeding Traits for Appearance and Structural Timber in Radiata Pine 

      Alzamora M., Rosa Maria (University of Canterbury. Forestry, 2010)
      The aims of this thesis were; firstly, to obtain economic values for radiata pine traits to produce appearance and structural lumber, and secondly to analyze the selection of efficient logs and profitable trees to substantiate ...
    • Variation in the effects of disturbance along a soil drainage gradient for a lowland temperate rainforest, South Westland, New Zealand 

      Rogers, Howard Michael (University of Canterbury. Forestry, 1995)
      Variation in the effects of disturbance across three differently aged glacial terraces in a terrace rimu (Dacrydium cupressinum) forest were investigated. Disturbance histories were reconstructed and associated patterns ...
    • Variation of the peak gust speed over an isolated hill 

      Clucas, Hong (University of Canterbury. Engineering, 1991)
      This thesis describes the behaviour of the peak-gust speed over an isolated hill by studying wind tunnel models. A brief description of relevant background theory from literature has been summarised. The Askervein Hill ...
    • A variational approach to optimal route location 

      Nicholson, Alan J. (University of Canterbury. Civil Engineering, 1973)
      This thesis describes the methods and results of an investigation into the applicability and usefulness of a variational approach to the determination of an optimal route location. The utilization of extremal field (dynamic ...
    • Vegetation Assessment to Understand the Effect of Feral Goat Populations on Native Flora Composition 

      Adkins, Nicholas (University of Canterbury. School of Forestry, 2012)
      A vegetation assessment was conducted to understand the effect of feral goats (Capra hircus) on the vegetation of Isolated Hill Scenic Reserve located in Southern Marlborough. New Zealand forests evolved without the ...
    • Vibration of bandsaws 

      Lengoc, Lan (University of Canterbury. Mechanical Engineering, 1990)
      The aim of this thesis was to investigate the vibrational characteristics of wide band bandsaws. Firstly, the vibration of bandsaw structures was considered. A computer program was developed to predict the natural ...
    • The vibration of initially curved simply supported and clamped beams with sliding end masses 

      Zhou, Yueming (University of Canterbury. Mechanical Engineering, 1990)
      The object of this study is to investigate the free vibration behaviour of slightly curved simply supported beams and clamped beams connected to axially sliding end masses. For the simply supported beam, two formulas for ...
