    • The lifting paddlewheel : a non-buoyant wheel enabling a high speed wheeled amphibious craft to run on the water surface 

      Alexander, K. V. (University of Canterbury. Mechanical Engineering, 1983)
      The lifting paddlewheel, (LPW), is a non-buoyant, bladed wheel similar to the paddlewheels used on riverboats, but is arranged to produce both propulsive and lift forces. Four suitable LPW's used on a high powered, amphibious ...
    • Light Flicker and Harmonic Modelling of Electrical Lighting 

      Frater, Lance Phillip (University of Canterbury. Electrical and Computer Engineering, 2015)
      Compact Fluorescent Lamps (CFLs) have emerged as cost-competitive, energy efficient direct replacements of the conventional incandescent lamp. However, little regard has been given to their widescale adoption in terms of ...
    • Light morphology and arabic information retrieval. 

      Algarni, Mohammed (University of Canterbury, 2016)
      The chief purpose of this study is to investigate the impact of mor- phology on Arabic Information Retrieval (AIR). In doing so, different forms of the surface word have to be examined as indexing terms in order to learn ...
    • Lignite Derived Humic Substances for Treatment of Acid Mine Drainage 

      Olds, William (University of Canterbury. Civil and Natural Resources, 2011)
      Addition of alkalinity to acid mine drainage (AMD) results in the neutralisation of acidity and precipitation of dissolved metals as insoluble hydroxides. Two aspects of the current AMD treatment practice at the Stockton ...
    • Limitations of Zone Models and CFD Models for Natural Smoke Filling in Large Spaces 

      Bong, Wen Jiann (University of Canterbury. Department of Civil and Natural Resources Engineering, 2012)
      This research report examines the use of zone modelling compared with CFD modelling to determine when zone model approximation is valid and when a CFD model might be required. A series of computer simulations with enclosures ...
    • Limited ductility design of reinforced concrete columns. 

      Soesianawati, M. T. (University of Canterbury. Department of Civil Engineering, 1986)
      This report describes an experimental and analytical investigation of the strength and ductility of reinforced concrete columns. Four columns of square cross-section were tested under axial compression loading and cyclic ...
    • Line focus solar Stirling domestic power generation 

      Trolove, Hamish P. (University of Canterbury. Mechanical Engineering, 1994)
      This thesis has found that to generate electricity for a domestic supply, the use of a two stage line focus concentrator coupled to a Stirling engine by way of a heat pipe is very inefficient, and the end result (useful ...
    • Linear and nonlinear integral equation population models. 

      Yamamoto, Shinji (University of Canterbury. Mathematics and Statistics, 2002)
      This thesis is concerned with population models by using integral equations. These equations are formulated by using concepts of the continuous time delay (bounded and unbounded), concepts of population history, concepts ...
    • Linear transceivers for MIMO relays 

      Shang, Cheng Yu Andy (University of Canterbury. Electrical and Electronic Engineering, 2014)
      Relays can be used in wireless communication systems to provide cell coverage extension, reduce coverage holes and increase throughput. Full duplex (FD) relays, which transmit and receive in the same time slot, can have a ...
    • Linkage Synthesis and Optimisation Techniques with Skiboard Product Design Case Study 

      Kauke, Lisa Marie (University of Canterbury. Mechanical Engineering, 2010)
      This thesis explores the design development and experimental testing of a planar linkage for the Skiboard, a novel snowsports equipment device. The Skiboard, similar to a skateboard in appearance and style of use, combines ...
    • Liquefaction evaluation in stratified soils. 

      Rhodes, Aimee (University of Canterbury, 2017)
      The Canterbury Earthquake Sequence (CES) of 2010-2011 caused widespread liquefaction in many parts of Christchurch. Observations from the CES highlight some sites were liquefaction was predicted by the simplified method ...
    • Liquefaction-induced lateral spreading in the 2010-2011 Canterbury earthquakes 

      Robinson, Kelly M. (University of Canterbury, 2016)
      Liquefaction-induced lateral spreading in large seismic events often results in pervasive and costly damage to engineering structures and lifelines, making it a critical component of engineering design. However, the ...
    • Liquid Aluminium Corrosion Characteristics of Cast Iron and Steel 

      Sidhu, Mandeep Singh (University of Canterbury. Mechanical Engineering, 2012)
      Cast iron and steel alloys are commonly used for tooling and structural components in Al production, Al die-casting and the aluminizing industry due to their favourable properties including high strength, good formability ...
    • Liquid Distribution And Falling Film Wetting In Dairy Evaporators 

      Broome, Steven (University of Canterbury. Department of Chemical and Process Engineering, 2005)
      Niro designed and built five near-identical milk evaporators for Fonterra’s production site at Clandeboye and five at the Edendale site. Tubes in the Clandeboye evaporators often fouled excessively and occasionally blocked, ...
    • List of Qualitas Code Corpus Programs used for Encapsulation Research
