Higher dimensional Taub-NUT spaces and applications
(University of Waterloo, 2006)In the first part of this thesis we discuss classes of new exact NUT-charged solutions in four dimensions and higher, while in the remainder of the thesis we make a study of their properties and their possible applications. ... -
Higher Gauge Theory and Discrete Geometry
(University of Waterloo, 2023-06-05)In four dimensions, gravity can be seen as a constrained topological model. This provides a natural way to construct quantum gravity models, since topological models are relatively straightforward to quantize. Difficulty ... -
Higher Order Random Walks, Local Spectral Expansion, and Applications
(University of Waterloo, 2020-09-16)The study of spectral expansion of graphs and expander graphs has been an extremely fruitful line of research in Mathematics and Computer Science, with applications ranging from random walks and fast sampling to optimization. ... -
Higher-Dimensional Kloosterman Sums and the Greatest Prime Factor of Integers of the Form a_1a_2\cdots a_{k+1}+1
(University of Waterloo, 2007-08-29)We consider the greatest prime factors of integers of certain form. -
Higher-order Losses and Optimization for Low-level and Deep Segmentation
(University of Waterloo, 2021-12-21)Regularized objectives are common in low-level and deep segmentation. Regularization incorporates prior knowledge into objectives or losses. It represents constraints necessary to address ill-posedness, data noise, outliers, ... -
A Highly Active RNA-Cleaving DNAzyme with Accelerated Activity by Ethanol and by Freezing
(University of Waterloo, 2018-04-27)DNAzymes are functional DNA molecules with catalytic activities. The EtNa is an example of a RNA-cleaving DNAzyme that catalyzes the cleavage reaction of a phosphodiester bond in the presence of metal ions, such as Na+ or ... -
Highly Crosslinked Natural Rubber-Cellulose Nanocrystals Composites for Sustainable Material Applications
(University of Waterloo, 2024-04-24)In a bid to develop environmentally friendly rubber materials, the use of renewable and sustainable additives and reinforcing fillers that could provide suitable mechanical property enhancement is of great interest. In ... -
Highly Efficient Deep Intelligence via Multi-Parent Evolutionary Synthesis of Deep Neural Networks
(University of Waterloo, 2020-02-11)Machine learning methods, and particularly deep neural networks, are a rapidly growing field and are currently being employed in domains such as science, business, and government. However, the significant success of neural ... -
Highly Efficient Planar Antenna System Based on the Planar Waveguide Technology for Low Cost Millimeter-Wave Applications
(University of Waterloo, 2011-11-11)This thesis investigates the integration of planar antennas, such as Dielectric Resonator Antennas (DRAs) to the planar waveguide structure, specifically the Substrate Integrated Waveguide (SIW) for high radiation efficiency ... -
Highly Filled, Durable, and Sustainable Wood-Plastic Composites from Recycled Thermoplastics
(University of Waterloo, 2022-09-26)The increasing concern for environmental sustainability and the accumulation of solid waste (e.g. single-use plastics) has led to an increased interest in the utilization of renewable feedstocks and recycling of plastics ... -
Highly Non-Convex Crossing Sequences
(University of Waterloo, 2012-05-18)For a given graph, G, the crossing number crₐ(G) denotes the minimum number of edge crossings when a graph is drawn on an orientable surface of genus a. The sequence cr₀(G), cr₁(G), ... is said to be the crossing sequence ... -
Highly Scalable and Secure Mobile Applications in Cloud Computing Systems
(University of Waterloo, 2013-04-25)Cloud computing provides scalable processing and storage resources that are hosted on a third-party provider to permit clients to economically meet real-time service demands. The confidentiality of client data outsourced ... -
Highway Development Decision-Making Under Uncertainty: Analysis, Critique and Advancement
(University of Waterloo, 2011-01-20)While decision-making under uncertainty is a major universal problem, its implications in the field of transportation systems are especially enormous; where the benefits of right decisions are tremendous, the consequences ... -
Hip & Spine Mechanics - Understanding the linkage from several perspectives of injury mechanisms to rehabilitation using biomechanical modelling
(University of Waterloo, 2020-01-08)One recent megatrend in medicine is that of “precision medicine” whereby a precise diagnosis leads to a precise intervention for superior results. This thesis was undertaken to enhance the understanding of spine and hip ... -
