    • Dynamic cybersecurity modelling and analysis. 

      Enoch, Simon Yusuf (University of Canterbury, 2018)
      It is difficult to assess the security of modern networks, such as Cloud and software defined networks, because they are usually dynamic with configuration changes (e.g., changes in topology, firewall rules, etc). Graphical ...

      Turner, R.; Duke, R.; Walton, S. (University of Canterbury. Electrical and Computer Engineering., 2007)
      A controller, suitable for medium to high power switching converters (1kW to 1MW), is proposed that dynamically changes the output PWM carrier frequency. The control objective is to optimise the choice of switching ...
    • A Dynamic Function for Energy Return on Investment 

      Dale, M.; Krumdieck, S.; Bodger, P. (University of Canterbury. Electrical and Computer EngineeringUniversity of Canterbury. Mechanical Engineering, 2011)
      Most estimates of energy-return-on-investment (EROI) are “static”. They determine the amount of energy produced by a particular energy technology at a particular location at a particular time. Some “dynamic” estimates are ...

      Objective: To validate the methodology for the Dynamic Insulin Sensitivity and Secretion Test (DISST) and to demonstrate its potential in clinical and research settings. Methods: 123 men and women had routine clinical and ...
    • Dynamic Interaction between Machine, Tool, and Substrate in Bobbin Friction Stir Welding 

      Sued, M.K.; Pons, Dirk J. (University of Canterbury. Mechanical Engineering, 2016)
      The bobbin friction stir welding (BFSW) process has benefits for welding aluminium alloy 6082-T6 in the boat-building industry. However this alloy is difficult to weld in the thin state. There are a large number of process ...
    • Dynamic Modeling of Organic Rankine Cycle (ORC) System for Fault Diagnosis and Control System Design 

      Choi S; Krumdieck, SP (Geothermal Insistute, University of Auckland, 2016)
      Dynamic simulation plays an important role of providing a higher-level of process analysis of the system and supporting system configuration, operation, maintenance, diagnosis and design of the control system. The purpose ...
    • Dynamic Orientation Sensing for Augmented Reality Using a Dual Axis Accelerometer 

      Keir, M.; Hann, C.E.; Chase, J.G.; Chen, X.Q. (University of Canterbury. Mechanical Engineering., 2008)
      Accurate viewpoint tracking for Augmented Reality applications is a challenging task. This paper presents a new model-based approach to tracking dynamic orientation using accelerometers. However, the inverted pendulum model ...
    • Dynamic physical analysis of long term economy-environment options 

      Ryan, Grant James (University of Canterbury. Chemical Engineering, 1995)
      This thesis presents a methodology for structural economy-environment simulation modelling (SEESM), and a demonstration of its application to New Zealand. The problem analysed in this thesis is the identification of long ...
    • A dynamic random channel reservation for MAC protocols in multimedia wireless networks. 

      Kao, Enoch Chia-chi (University of Canterbury. Computer Science and Software Engineering, 2001)
