Dietary Exposure Assessment and Contaminants Biomonitoring in the Dehcho Region, Northwest Territories: Exploring the Relationship Between Mercury Exposure, Omega-3 Fatty Acid Status, and Fish Consumption
(University of Waterloo, 2017-11-29)Background: Fish are often rich in essential micronutrients including omega-3 fatty acids (FA), and are a cultural and dietary staple in traditional food systems of First Nations communities in the Canadian subarctic. ... -
Dieting and health-related behaviours among adolescent girls: A longitudinal analysis of data from a school-based study
(University of Waterloo, 2016-06-30)Objective: Dieting to lose weight is extremely common among adolescents, especially girls, and is driven by multiple factors, including individual traits and societal standards regarding body weight and shape. Dieting is ... -
The Diets of On-reserve First Nations Youth: An Exploration of the Factors Associated with Healthy Food Choices and the Impact of School and Community Programs
(University of Waterloo, 2016-01-19)Background. In Canada, First Nations (FN) people experience poorer health outcomes and shorter life expectancies than non-Aboriginal people. Of particular concern are the high and rising prevalence rates of overweight and ... -
The Difference in Peripheral Chemosensitivity Between Trained and Untrained Individuals during Exercise
(University of Waterloo, 2022-01-10)Hypercapnic chemosensitivity is the ventilatory response to increased partial pressure of CO2 and is the result of central and peripheral chemosensor stimulation. The hypercapnic chemosensitivity of the peripheral ... -
Differential Diagnosis of Complex Conditions in Paleopathology: A Mutational Spectrum Approach
(University of Waterloo, 2021-01-06)The expression of mutations causing complex conditions varies considerably on a scale of mild to severe referred to as a mutational spectrum. Capturing a complete picture of this scale in the archaeological record through ... -
Differential Equations and Depth First Search for Enumeration of Maps in Surfaces
(University of Waterloo, 1999)A map is an embedding of the vertices and edges of a graph into a compact 2-manifold such that the remainder of the surface has components homeomorphic to open disks. With the goal of proving the Four Colour Theorem, ... -
The Differential Geometry of Instantons
(University of Waterloo, 2009-08-07)The instanton solutions to the Yang-Mills equations have a vast range of practical applications in field theories including gravitation and electro-magnetism. Solutions to Maxwell's equations, for example, are abelian gauge ... -
The Differential Influence of Strategy Selection and Implementation on Probability Matching in a Binary Prediction Task
(University of Waterloo, 2017-12-08)Probability Matching is a common and suboptimal strategy often used by participants in a Binary Prediction Task. A plethora of research has examined why participants engage in Probability Matching and also what factors ... -
Differential Operators on Manifolds with G2-Structure
(University of Waterloo, 2020-12-16)In this thesis, we study differential operators on manifolds with torsion-free G2-structure. In particular, we use an identification of the spinor bundle S of such a manifold M with the bundle R ⊕ T*M to reframe statements ... -
Differential Privacy for Nearest Neighbor Queries
(University of Waterloo, 2022-08-16)We examine the problem of providing differential privacy for nearest neighbor queries. Very few mechanisms exist that achieve this, most notable geo-indistinguishability in the context of location privacy. However it uses ... -
Differentially Private Learning with Noisy Labels
(University of Waterloo, 2020-05-28)Supervised machine learning tasks require large labelled datasets. However, obtaining such datasets is a difficult task and often leads to noisy labels due to human errors or adversarial perturbation. Recent studies have ... -
Differentially Private Online Aggregation
(University of Waterloo, 2022-01-13)Database operations are often performed in batch mode, i.e. the analyst issuing the query must wait till the database has been processed in its entirety before getting feedback. Batch mode is inadequate for large databases ... -
Differentially Private Searchable Symmetric Encryption Scheme with Configurable Pattern Leakage
(University of Waterloo, 2019-12-19)Searchable symmetric encryption (SSE) allows a data owner to outsource its data to a cloud server while maintaining the ability to search over it. Most existing SSE schemes leak access-pattern leakage, and thus are vulnerable ... -
Differentially Private Simple Genetic Algorithms
(University of Waterloo, 2021-12-13)We study the differentially private (DP) selection problem, where the goal is to select an item from a set of candidates that approximately maximizes a given objective function. The most common solution to this problem is ... -
Differentially-private Multiparty Clustering
(University of Waterloo, 2023-09-13)In an era marked by the widespread application of Machine Learning (ML) across diverse domains, the necessity of privacy-preserving techniques has become paramount. The Euclidean k-Means problem, a fundamental component ... -
Differentiating Gait Behaviors between Early-Stage Dementia with Lewy Bodies and Parkinson’s Disease
(University of Waterloo, 2023-01-20)Dementia with Lewy bodies (DLB) and Parkinson’s disease (PD) can be difficult to differentially diagnose, given the overlap in clinical and pathological features. Evidence suggests gait may be a sensitive and selective ... -
The Differing Influences of Soil Moisture and Antecedent Soil Moisture on the Timing and Magnitude of N2O Production
(University of Waterloo, 2012-10-22)Riparian soils are thought to be potential hotspots for nitrous oxide (N2O) fluxes from incomplete denitrification, with soil moisture cited as a primary controller, however, because there are multiple potential pathways ... -
Diffuse Solid-Fluid Interface Method for Dispersed Multiphase Flows
(University of Waterloo, 2018-08-30)Industrial chemical engineering processes such as bubble columns, reactors and separators involve multiphase flows of two or more fluids. In order to improve the design and operation of these processes, an understanding ... -
Diffusion-Reaction Modeling, Non-Linear Dynamics, Feedback, Bifurcation and Chaotic Behaviour of the Acetylcholine Neurocycle and Their Relation to Alzheimer's and Parkinson's Diseases
(University of Waterloo, 2010-04-29)The disturbances and abnormalities occurring in the components of the Acetylcholine (ACh) neurocycle are considered one of the main features of cholinergic sicknesses like Parkinson’s and Alzheimer’s diseases. A fundamental ... -
