Hydrodynamic Modelling of the Electronic Response of Carbon Nanotubes
(University of Waterloo, 2007-02-08)The discovery of carbon nanotubes by Iijima in 1991 has created a torrent of new research activities. Research on carbon nanotubes ranges from studying their fundamental properties, such as their electron band structure ... -
Hydrodynamic Stability of Free Convection from an Inclined Elliptic Cylinder
(University of Waterloo, 2006)The steady problem of free convective heat transfer from an isothermal inclined elliptic cylinder and its stability is investigated. The cylinder is inclined at an arbitrary angle with the horizontal and immersed in an ... -
Hydrodynamics of the Yucatan peninsula carbonate aquifer: surface flow, inland propagation and mixing
(University of Waterloo, 2021-04-28)This thesis is a collection of three investigations into the hydrodynamics and hydrogeology of the Yucatan Peninsula, Mexico. The first investigation models potential mangrove-groundwater interactions as a box model. We ... -
The hydrodynamics of two-dimensional oscillating flows over ripples: the effect of asymmetries in ripple shape and currents
(University of Waterloo, 2017-04-28)The research presented in this thesis involved consideration of three increasingly asymmetric oscillatory flows over two ripple profiles, one of which is asymmetric and represents a small deviation from a symmetric ripple. ... -
Hyperpfaffians in Algebraic Combinatorics
(University of Waterloo, 2006)The pfaffian is a classical tool which can be regarded as a generalization of the determinant. The hyperpfaffian, which was introduced by Barvinok, generalizes the pfaffian to higher dimension. This was further ... -
Hypothesis Testing in Finite Mixture Models
(University of Waterloo, 2007-12-14)Mixture models provide a natural framework for unobserved heterogeneity in a population. They are widely applied in astronomy, biology, engineering, finance, genetics, medicine, social sciences, and other areas. An ... -
Hysteresis bifurcation and application to delayed FitzHugh-Nagumo neural systems
(Elsevier, 2021-08)Hysteresis dynamics has been described in a vast number of biological experimental studies. Many such studies are phenomenological and a mathematical appreciation has not attracted enough attention. In the paper, we explore ... -
Ideal Clutters
(University of Waterloo, 2018-04-24)Let E be a finite set of elements, and let C be a family of subsets of E called members. We say that C is a clutter over ground set E if no member is contained in another. The clutter C is ideal if every extreme point of ... -
Identifying Behavioural Implications of Source Code Changes
(University of Waterloo, 2013-01-25)The dynamic behaviour of a software system changes as a consequence of developer’s static source code modifications. In this thesis, we improve upon a previous approach that combines static and dynamic analyses to categorize ... -
Identifying patterns of alcohol use among secondary school students in Canada: A multilevel latent class analysis
(Elsevier, 2020-01)Harm from alcohol use depend not only on the volume of consumption but also on drinking patterns. This study identifies patterns of alcohol consumption in youth and investigates how these patterns vary across schools and ... -
Identifying regions of trusted prediction
(University of Waterloo, 2021-07-20)Quantifying the probability of a label prediction being correct on a given test point or a given sub-population enables users to better decide how to use and when to trust machine learning derived predictors. In this work, ... -
Identity Management and Resource Allocation in the Network Virtualization Environment
(University of Waterloo, 2009-01-23)Due to the existence of multiple stakeholders with conflicting goals and policies, alterations to the existing Internet architecture are now limited to simple incremental updates; deployment of any new, radically different ... -
The illness-death model for family studies
(Oxford University Press, 2021-07)Family studies involve the selection of affected individuals from a disease registry who provide right-truncated ages of disease onset. Coarsened disease histories are then obtained from consenting family members, either ... -
Image-Based Relighting
(University of Waterloo, 2010-04-22)This thesis proposes a method for changing the lighting in some types of images. The method requires only a single input image, either a studio photograph or a synthetic image, consisting of several simple objects placed ... -
The Impact Of Aggregating Serogroups In Dynamic Models Of Neisseria Meningitidis Transmission
(BioMed Central, 2015-07-30)Background: Neisseria meningitidis (Nm) is a pathogen of multiple serogroups that is highly prevalent in many populations. Serogroups associated with invasive meningococcal disease (IMD) in Canada, for example, include A, ... -
The Impact of Code Ownership of DevOps Artefacts on the Outcome of DevOps CI Builds
(University of Waterloo, 2023-12-22)This study focuses on factors that may influence the outcomes of CI builds triggered by commits modifying and/or adding DevOps artefacts to the projects, i.e., DevOps-related CI builds. In particular, code ownership of ... -
The Impact of Domain Knowledge on the Effectiveness of Requirements Engineering Activities
(University of Waterloo, 2014-05-21)One of the factors that seems to influence an individual’s effectiveness in requirements engineering activities is his or her knowledge of the problem being solved, i.e., domain knowledge. While in-depth domain knowledge ... -
The Impact Of Human-Environment Interactions On The Stability Of Forest-Grassland Mosaic Ecosystems
(Nature Publishing Group, 2013-09-19)Forest-grassland mosaic ecosystems can exhibit alternative stables states, whereby under the same environmental conditions, the ecosystem could equally well reside either in one state or another, depending on the initial ... -
The Impact of Information Technology Investments on Hospital Performance and Quality of Care
(University of Waterloo, 2011-10-18)The business value of Information Technology (measuring the impact of IT investments on organizational productivity and efficiency) and quantifying Information technology’s tangible and intangible benefits havebeen significant ... -
The Impact of Internal Solitary Waves on the Nutrient Circulation System
(University of Waterloo, 2013-07-25)Internal waves in lakes and oceans are ubiquitous whenever a density stratification is present. These waves are relatively slow moving, can be large in extent and have long time scales. As these waves are so common, it is ...
