    • Optimizing phylogenetic diversity across two trees 

      Bordewich, M.; Semple, C.; Spillner, A. (University of Canterbury. Mathematics and Statistics, 2009)
      We present a polynomial-time algorithm for finding an optimal set of taxa that maximizes the weighted sum of the phylogenetic diversity across two phylogenetic trees. This resolves one of the challenges proposed as part ...
    • Optimizing phylogenetic diversity under constraints 

      Moulton, Vincent; Semple, Charles; Steel, Mike (University of Canterbury, 2006)
      Phylogenetic diversity (PD) is a measure of the extent to which different subsets of taxa span an evolutionary tree, and provides a quantitative tool for studying biodiversity conservation. Recently, it was shown that the ...
    • Optimizing phylogenetic diversity under constraints 

      Moulton, V.; Semple, C.; Steel, M. (University of Canterbury. Mathematics and Statistics., 2007)
      Phylogenetic diversity (PD) is a measure of the extent to which different subsets of taxa span an evolutionary tree, and provides a quantitative tool for studying biodiversity conservation. Recently, it was shown that the ...
    • Optimizing wind-diesel hybrid energy systems including a demand side management strategy 

      Krumdieck S; Frye J (2014)
      The New Zealand research station at Scott Base, Antarctica is used as a study of incorporation of wind power generation into an isolated micro-grid powered by diesel generator. The generation plant at Scott Base uses ...
    • Optimum Control of Flow around a Circular Cylinder with Non-Uniform Suction 

      Ramsay JR; Sellier M; Ho WH (2019)
      In the present study, numerical investigations were performed to determine the optimum non-uniform suction profiles to control the flow around a circular cylinder in the range of Reynolds numbers 4<𝑅𝑒<200. To investigate ...
    • Optimum design of small-signal microwave amplifiers with specified stability safety margin 

      Eccleston, K.W. (University of Canterbury. Electrical and Computer Engineering, 2000)
      When employing conditionally stable transistors in microwave amplifier design, it is impossible to have both ports perfectly matched. One can easily design for a perfect match at one of the ports, but the resulting ...
    • An Options Analysis for the Commercial and Economic Development of Offshore Methane Hydrates as a Future Energy Option for New Zealand 

      Chong, Kevin (New Zealand Centre for Advanced Engineering, 2010)
      In this study, we have synthesised the current state of scientific knowledge and international learning to develop a possible road map for the commercial production of methane hydrate in New Zealand. This road map anticipates ...
    • Optogenetic manipulation of freely moving C. elegans in an elastomeric environment mimicking and force-measuring chip 

      Qiu, Z.; Tu, L.; Xue, X.; Zhu, T.; Nock, V.; Li, Y.; Liu, X.; Wang, W. (University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Biomolecular Interaction Centre, 2014)
      This paper presents integration of optogenetic illumination of C. elegans neural circuits and muscular force measurement in a structured microfluidic chip mimicking the C. elegans soil habitat. The integrated system deploys ...
    • Ordinal and convex assumptions in phylogenetic tree reconstruction 

      Candy, Robin (University of Canterbury. School of Mathematics and Statistics, 2014)
      Phylogenetics is a field primarily concerned with the reconstruction of the evolutionary history of present day species. Evolutionary history is often modeled by a phylogenetic tree, similar to a family tree. To recreate ...
    • Organ Failure and Tight Glycemic Control in the SPRINT Study 

      Chase, J.G.; Pretty, C.G.; Pfeifer, L.; Shaw, G.M.; Preiser, J-C.; Lin, J.; Hewett, D.; Moorhead, K.T.; Desaive, T.; LeCompte, A.J. (University of Canterbury. Mechanical Engineering, 2010)
      Introduction: Intensive care unit mortality is strongly associated with organ failure rate and severity. The sequential organ failure assessment (SOFA) score is used to evaluate the impact of a successful tight glycemic ...
    • Organisational resilience in New Zealand 

      McManus, Sonia Therese (University of Canterbury. Civil Engineering, 2008)
      Organisations maintain our economy; they provide jobs, goods, services and a sense of community. The increasingly globalised nature of the modern world has lead to organisations facing threats that often are not recognise ...
    • Organizational Operations Planning and Decision-Making During Extreme Events: The New Zealand State Highway Organizations Case 

      Ferreira, F.; Dantas, A.; Seville, E.; Giovinazzi, S. (University of Canterbury. Civil and Natural Resources Engineering, 2010)
      Operations planning and decision-making research for emergency management have increased in both academia and industry due to catastrophic events that have occurred in the past two decades. Recovery and reconstruction are ...
    • Oscillating Hydrofoil Propulsion for Human-Powered Watercraft Applications 

      Fernandez, Rajan (University of Canterbury. Mechanical Engineering, 2013)
      Unlike conventional propellers, flapping wings may generate large amplitude oscillating forces, which can make them difficult to incorporate into a craft design. This is particularly true for a single, vertically oscillating ...
    • OSGART - A Pragmatic Approach to MR 

      Looser, J.; Grasset, R.; Seichter, H.; Billinghurst, M. (University of Canterbury. Human Interface Technology Laboratory., 2006)
      We are presenting a software development framework called OSGART for Rapid Application Developement (RAD) in the domain of Mixed Reality (MR). This toolkit is being developed as an extension to OpenSceneGraph [3]. It ...
    • OSGARToolKit: Tangible + Transitional 3D Collaborative Mixed Reality Framework 

      Grasset, R.; Looser, J.; Billinghurst, M. (University of Canterbury. Human Interface Technology Laboratory., 2005)
      In recent years there have been a number of software frameworks proposed for developing augmented reality (AR) applications. However these frameworks typically do not address three types of interfaces; tangible, ...
    • Our Oceans: A journey of understanding 

      Sherwood, Alan (Centre for Advanced Engineering, University of Canterbury, 2001)
