Surface solar radiation and lake productivity: Investigating a global relationship
(University of Waterloo, 2021-04-14)In recent decades, the intensity and frequency of lake algal blooms have been increasing worldwide. In addition to potentially toxic effects for humans and wildlife, intense algal blooms negatively impact recreation and ... -
In-situ monitoring and intermittent controller for adaptive trajectory generation during laser directed energy deposition via powder feeding
(University of Waterloo, 2023-03-27)Laser Directed Energy Deposition (LDED) is one of the advanced manufacturing technologies for building near-net-shaped engineering components in a layer-by-layer fashion using high-power lasers as an energy source. LDED ... -
Quantifying Aquatic Carbon and Nitrogen Dynamics and Greenhouse Gas Mitigation Potential in Riparian Agroforestry Zones
(University of Waterloo, 2023-03-27)Agricultural intensification in Canada has led to a loss of riparian areas, which has resulted in the degradation of freshwater aquatic ecosystems due to an increasing amount of fertilizer and nutrients being introduced ... -
Improving the multiscale morphological and mechanical properties of laser welded Al-Si coated 22MnB5 press-hardened steels
(University of Waterloo, 2023-03-27)In the automotive industry, the demand for reduced vehicle weight, improved safety and enhanced crashworthiness qualities continues to rise which introduces the need for parts and components with tailored properties. This ... -
DeepThInk: Designing and Probing Human-AI Co-creation in Digital Art Therapy
(University of Waterloo, 2023-03-27)Art therapy has been an essential form of psychotherapy to facilitate psychological well-being, which has been promoted and transformed by recent technological advances into digital art therapy. However, the potential of ... -
Designing a living barrier fortifying the coast against extreme climate events to reharmonize the identity of people, land, and water on the Island of Efate, Vanuatu
(University of Waterloo, 2023-03-24)On the Pacific island of Vanuatu, the connection the islanders have nurtured with the land and water is both evident and fundamental to their conception of life and legacy -the spirits of their ancestors are thought to ... -
An integrative investigation of liquid metal embrittlement in the Fe-Zn system: From responsible mechanisms to mitigation strategies
(University of Waterloo, 2023-03-23)Liquid metal embrittlement (LME) is a problematic phenomenon that results in the abrupt failure of a ductile metal that is exposed to a reactive liquid metal while simultaneously experiencing a tensile load. Despite extensive ... -
Surveilling Queerness and Queering Surveillance: The Techno-Social Making of Queer Identity in the US and Canada, 1939-Present.
(University of Waterloo, 2023-03-22)This dissertation positions itself at the intersection of two disparate areas of study: Queer theory and surveillance studies. It aims to tease out the ways that technologies of surveillance and Queer lifeways evolved ... -
A structural investigation of novel fungal polyglycine hydrolases
(University of Waterloo, 2023-03-22)Polyglycine hydrolases (PGH) are a family of fungal proteases that are known to cleave the polyglycine linker of Zea mays chitinase, ChitA, thwarting one mechanism of plant defense against fungal infection. Previously, ... -
Probabilistic Fretting Fatigue Analysis of Bridge Stay Cables at Saddle Supports
(Taylor and Francis, 2020-01)Saddle systems have been used on recent projects to support the cables in cable-stayed and extradosed bridge structures. A major design consideration for these anchorage systems is the in-service fretting fatigue behaviour ... -
A Review of the Fatigue Limit for Steel Bridges under Ontario Highway Traffic Loading
(Canadian Science Publishing, 2022-12)In many design codes for roadway bridges, it is required that a design truck be passed over influence lines for stress at various locations on the bridge to obtain nominal stress ranges for design. For the fatigue design ... -
Response of vegetation and net ecosystem carbon dioxide exchange at different peatland microforms following water table drawdown
(American Geophysical Union, Wiley, 2006-05-17)Northern peatlands are significant stocks of terrestrial soil carbon, and it has been predicted that warmer temperatures and lower water tables resulting from climate change will convert these ecosystems into sources for ... -
Dynamics of biogenic gas bubbles in peat and their effects on peatland biogeochemistry
(American Geophysical Union, Wiley, 2005-01-18)Production and emission of peat gas has attracted great interest because substantial amounts of methane (CH4) are emitted to the atmosphere from peat soils. Many studies indicate supersaturation of CH4 in peat water, ... -
A softly optimal Monte Carlo algorithm for solving bivariate polynomial systems over the integers
(Elsevier, 2016-06)We give an algorithm for the symbolic solution of polynomial systems in Z[X,Y]. Following previous work with Lebreton, we use a combination of lifting and modular composition techniques, relying in particular on Kedlaya ... -
On the evaluation of some sparse polynomials
(American Mathematical Society, 2018)We give algorithms for the evaluation of sparse polynomials of the form P=p0 + p1 x + p2 x^4 + ... + p_{n-1} x^{(N-1)^2} for various choices of coefficients . First, we take p_i=p^i, for some fixed p; in this case, we ... -
Incorporating Breastfeeding-Related Variability with Physiologically Based Pharmacokinetic Modeling to Predict Infant Exposure to Maternal Medication Through Breast Milk: a Workflow Applied to Lamotrigine
(Springer Nature, 2021-05-17)Current methods to assess risk in infants exposed to maternal medication through breast milk do not specifically account for infants most vulnerable to high drug exposure. A workflow applied to lamotrigine incorporated ... -
