Effect of Prevalence on Relevance Assessing Behaviour
(University of Waterloo, 2011-08-29)Relevance assessing is an important part of information retrieval (IR) evaluation in addition to being something that all users of IR systems must do as part of their search for relevant documents. In this thesis, we present ... -
The Effect of Time-Varying Boundary Conditions on the Generation of Sum and Difference Frequency Tones in a Coaxial Loudspeaker
(University of Waterloo, 2009-06-22)A coaxial loudspeaker in which the woofer and tweeter oscillate at angular frequencies ω_1 and ω_2 respectively, is known to produce sum and difference frequencies ω_± = ω_1 ± ω_2. The generation of these can be attributed ... -
Effective and Efficient Optimization Methods for Kernel Based Classification Problems
(University of Waterloo, 2014-04-22)Kernel methods are a popular choice in solving a number of problems in statistical machine learning. In this thesis, we propose new methods for two important kernel based classification problems: 1) learning from highly ... -
Effective Dimensionality Control in Quantitative Finance and Insurance
(University of Waterloo, 2017-09-06)It is well-known that dimension reduction techniques such as the Brownian bridge, principal component analysis, linear transformation could increase the efficiency of Quasi-Monte Carlo (QMC) methods. Caflisch et al. (1997), ... -
Effective Math-Aware Ad-Hoc Retrieval based on Structure Search and Semantic Similarities
(University of Waterloo, 2023-09-15)Despite the prevalence of digital scientific and educational contents on the Internet, only a few search engines are capable to retrieve them efficiently and effectively. The main challenge in freely searching scientific ... -
Effective Use of SSDs in Database Systems
(University of Waterloo, 2018-05-07)With the advent of solid state drives (SSDs), the storage industry has experienced a revolutionary improvement in I/O performance. Compared to traditional hard disk drives (HDDs), SSDs benefit from shorter I/O latency, ... -
Effects of a Geostrophic Current on the Propagation and Generation of Internal Tides
(University of Waterloo, 2021-08-30)Internal tides (ITs) are ubiquitous in a stratified ocean where they are generated in response to tidal flows incident upon bottom topography. Along-shelf currents or boundary currents are ocean currents commonly observed ... -
The Effects of Confinement on Kelvin-Helmholtz Billows
(University of Waterloo, 2016-01-15)Turbulence is one of the most interesting and important, yet poorly understood, aspects of fluid mechanics. The transition from an unstable laminar flow to a fully turbulent flow can follow many paths depending on the ... -
Effects of Developmental Heuristics for Natural Language Learning
(University of Waterloo, 2003)Machine learning in natural language has been a widely pursued area of research. However, few learning techniques model themselves after human learning, despite the nature of the task being closely connected to human ... -
The effects of dielectric decrement and finite ion size on differential capacitance of electrolytically gated graphene
(Elsevier, 2018-06-01)We analyze the effects of dielectric decrement and finite ion size in an aqueous electrolyte on the capacitance of a graphene electrode, and make comparisons with the effects of dielectric saturation combined with finite ... -
The Effects of Extrinsic and Intrinsic Noise on a Tumour and a Proposed Metastasis Model
(University of Waterloo, 2015-11-30)Cancer is a ubiquitous disease that afflicts millions of people worldwide and we will undoubtedly encounter it at some point in our lives, whether it be random strangers on the news, or someone much closer. As such, research ... -
The effects of flagellar hook compliance on motility of monotrichous bacteria: A modeling study
(AIP Publishing, 2012-06)A crucial structure in the motility of flagellated bacteria is the hook, which connects the flagellum filament to the motor in the cell body. Early mathematical models of swimming bacteria assume that the helically shaped ... -
Effects of Personality Traits and Emotional Factors in Pull Request Acceptance.
(University of Waterloo, 2019-08-26)Social interactions in the form of discussion are an indispensable part of collaborative software development. The discussions are essential for developers to share their views and to form a strong relationship with other ... -
Effects of the Dielectric Environment on the Electrical Properties of Graphene
(University of Waterloo, 2013-08-30)This thesis provides the study of graphene’s electrostatic interaction with the substrate surrounding it. Mathematical models based on current experimental configurations of graphene field-effect transistors (FET) are ... -
The Effects of the Earth's Rotation on Internal Wave Near-resonant Triads and Weakly Nonlinear Models
(University of Waterloo, 2007-08-24)This thesis investigates the effects of the earth's rotation on internal waves from two perspectives of nonlinear internal wave theory: near-resonant triads and weakly nonlinear models. We apply perturbation theory ... -
