    • Validation of Volumetric Contact Dynamics Models 

      Boos, Michael (University of Waterloo, 2011-05-05)
      A volumetric contact dynamics model has been proposed by Gonthier et al. [1, 2, 3] for the purpose of rapidly generating reliable simulations of space-based manipulator contact dynamics. By assuming materials behave as a ...
    • The Valuation and Risk Management of a DB Underpin Pension Plan 

      Chen, Kai (University of Waterloo, 2007-08-02)
      Hybrid pension plans offer employees the best features of both defined benefit and defined contribution plans. In this work, we consider the hybrid design offering a defined contribution benefit with a defined benefit ...
    • Value Congruence in Perception and Support of Organizational Visions 

      Leung, Kevin (University of Waterloo, 2012-08-30)
      Leadership scholars assume that the values espoused in an organizational vision have motivational effects on employee actions, but this claim has rarely been subject to empirical testing. Two studies examined whether ...
    • The Value of Agricultural Census Data in Carbon Cycle Studie 

      Chan, Eric (University of Waterloo, 2011-05-24)
      Agricultural census data have been identified to possess the potential to provide constraints on carbon uptake by croplands at the regional scale. In this study, we build on previous efforts and further assess this potential ...
    • Values and Co-production: Examining the Interface of Indigenous Peoples’ Understandings and Scientific Understandings 

      Isaac, David (University of Waterloo, 2015-08-31)
      In this thesis I will examine the role values play in the co-production of knowledge between traditional knowledge and science. In order to understand the role values play, I will first develop clearer definitions of ...
    • Valuing Hedge Fund Fees 

      Xiao, Li (University of Waterloo, 2006)
      This thesis applies a Partial Integral Differential Equation model, along with a Monte Carlo approach to quantitatively analyze the no arbitrage value of hedge fund performance fees. From a no-arbitrage point of view, ...
    • (VANET IR-CAS): Utilizing IR Techniques in Building Context Aware Systems for VANET 

      Nassar, Lobna (University of Waterloo, 2015-12-18)
      Most of the available context aware dissemination systems for the Vehicular Ad hoc Network (VANET) are centralized systems with low level of user privacy and preciseness. In addition, the absence of common assessment models ...
    • VAPEX Experiments in an Annular Packing of Glass Beads and the Numerical Simulation of VAPEX using Comsol® 

      Tam, Sindy (University of Waterloo, 2007-09-26)
      Vapour Extraction (VAPEX) is an in-situ bitumen recovery technique that utilizes light hydrocarbons to reduce the viscosity of bitumen. The mechanism of VAPEX is governed by the mass transfer of light hydrocarbons into ...
    • Vapour Diffusion Control in Framed Wall Systems Insulated with Spray Polyurethane Foam 

      Smith, Rachel Cecilia (University of Waterloo, 2009-04-30)
      The Intergovernmental Panel on Climate Change (IPCC) estimates that buildings account for 40% of the global energy use. The IPCC believes substantial improvements to building efficiency can be implemented easily by improving ...
    • Varactor-Based Tunable Planar Filters and Post-Fabrication Tuning of Microwave Filters 

      Rezazadeh Sereshkeh, Alborz (University of Waterloo, 2012-10-25)
      Post-fabrication tuning of filters is usually realized by adding number of elements for tuning the frequency and/or controlling the couplings between the resonators. The task of these tuning elements is to control resonators ...
    • Variability Anomalies in Software Product Lines 

      NADI, SARAH (University of Waterloo, 2014-08-07)
      Software Product Lines (SPLs) allow variants of a software system to be generated based on the configuration selected by the user. In this thesis, we focus on C based software systems with build-time variability using a ...
