      Valov, Pavel (University of Waterloo, 2014-10-28)
      Configurable software systems allow users to form configurations by selecting and deselecting features. The process of configuration creation may directly affect performance of the system in a non-linear way because of ...
    • Variability-Modelling Practices in Industrial Software Product Lines: A Qualitative Study 

      Nair, Divya Karunakaran (University of Waterloo, 2013-05-22)
      Many organizations have transitioned from single-systems development to product-line development with the goal of increasing productivity and facilitating mass customization. Variability modelling is a key activity in ...
    • Variable Ranking by Solution-path Algorithms 

      Wang, Bo (University of Waterloo, 2012-01-20)
      Variable Selection has always been a very important problem in statistics. We often meet situations where a huge data set is given and we want to find out the relationship between the response and the corresponding variables. ...
    • Variable Splitting as a Key to Efficient Image Reconstruction 

      Dolui, Sudipto (University of Waterloo, 2012-09-25)
      The problem of reconstruction of digital images from their degraded measurements has always been a problem of central importance in numerous applications of imaging sciences. In real life, acquired imaging data is typically ...
    • Variable-Structure Cable-Driven Parallel Robots 

      Rushton, Mitchell (University of Waterloo, 2022-05-16)
      Cable-driven parallel robots (CDPR) are a special class of robotic manipulators consisting of a rigid end effector suspended, constrained, and actuated by a number of length-varying cables. Since cable mass is typically ...
    • Variation in fish fatty acid concentrations among lakes in the Dehcho region of the Northwest Territories 

      Boag, Tara (University of Waterloo, 2020-12-22)
      Background: In the subarctic Dehcho region of the Northwest Territories, many remote communities rely on traditional foods, including fish, to supplement more expensive store-bought options. Fish are an excellent source ...
    • Variation of Force Amplitude and its Effects on Muscle Fatigue 

      Yung, Marcus (University of Waterloo, 2011-01-20)
      Current trends in industry are leaning towards specialized production systems and sedentary computer work tasks that are associated with low and less varying mechanical exposures. It has been suggested that physical ...
    • Variational Bayesian Learning and its Applications 

      Zhao, Hui (University of Waterloo, 2014-01-03)
      This dissertation is devoted to studying a fast and analytic approximation method, called the variational Bayesian (VB) method, and aims to give insight into its general applicability and usefulness, and explore its ...
    • Variational Inference for Text Generation: Improving the Posterior 

      Balasubramanian, Vikash (University of Waterloo, 2020-08-10)
      Learning useful representations of data is a crucial task in machine learning with wide ranging applications. In this thesis we explore improving representations of models based on variational inference by improving the ...
    • Variational Quantum Eigensolvers Applied to Problems in High Energy Physics 

      Ferguson, Ryan (University of Waterloo, 2021-01-13)
      Variational methods have long been used to study strongly-correlated quantum systems. Despite the successes of classical protocols, these are limited in the study of quantum systems, either due to numerical errors like the ...
    • Variational Spectral Analysis 

      Sendov, Hristo (University of Waterloo, 2000)
      We present results on smooth and nonsmooth variational properties of {it symmetric} functions of the eigenvalues of a real symmetric matrix argument, as well as {it absolutely symmetric} functions of the singular values ...
    • Variational Stokes with Polynomial Reduced Fluid Model 

      Panuelos, Jonathan (University of Waterloo, 2021-01-21)
      Standard fluid simulators often apply operator splitting to independently solve for pressure and viscous stresses. This decoupling, however, induces incorrect free surface boundary conditions. Such methods are unable to ...
    • Variations and Sources of Atmospheric CO2 Measured at East Trout Lake, Canada 

      Kim, Myung (University of Waterloo, 2016-01-15)
      Reducing uncertainties in projections of surface emissions of major greenhouse gases (GHGs) including CO2 relies on continuously improving our scientific understanding of the exchange processes between the atmosphere and ...
    • Variations in Northern Dolly Varden (Salvelinus malma malma) total mercury concentrations from the northwestern Canadian Arctic 

      Tran, Lilian (University of Waterloo, 2014-10-22)
      Mercury (Hg) is a ubiquitous contaminant with harmful impacts on the aquatic ecosystem as well as human health. Studies to date of the bioaccumulative effects of Hg on northern fishes have focussed on all but one of the ...
    • Variations on a Theme of Deep Time: From Geology to Architecture 

      Winter, Mathew Jeffrey Franklin (University of Waterloo, 2015-08-27)
      Through the lens of deep time, this thesis draws a comparison between geology and architecture, to create an architecture of simultaneity. Using Henri Bergson’s notion of the present containing all of the past within it, ...
    • Variations on a Theme: Graph Homomorphisms 

      Roberson, David E. (University of Waterloo, 2013-08-30)
      This thesis investigates three areas of the theory of graph homomorphisms: cores of graphs, the homomorphism order, and quantum homomorphisms. A core of a graph X is a vertex minimal subgraph to which X admits a ...
    • Variations on Acoustophoretic Microchannels: From the Facile to the Highly Capable 

      Samarasekera, Champika (University of Waterloo, 2018-05-31)
