Numerical Modelling of Mass Recovery During Thermal Conductive Heating
The primary objective of this thesis was to develop a computationally efficient numerical model for simulating the mass recovery of volatile organic compounds (VOCs) from dense non-aqueous phase liquid (DNAPL) source zones ... -
A Survey on The Self-Assembly of N-Heterocyclic Carbenes: The Influence of Noble Metal Surfaces
Monolayers formed by N-heterocyclic carbenes on the (111) faces of noble metal surfaces are characterized by means of scanning tunneling microscopy. Monolayer films were prepared through in vacuo deposition. A wide range ... -
Secondary Motion in Meandering Streams: An Experimental Study
Meandering is a common plan shape acquired by rivers. Its prevalence in the environment and highly dynamic nature make the mechanics of flow in meandering streams a great interest for engineers and scientists. Meandering ... -
How Fusarium graminearum GPCRs Contribute To Fungal Virulence On Wheat
Fusarium graminearum is the principal causal agent of Fusarium Head Blight, one of the most destructive diseases of wheat. Infection of wheat by F. graminearum results in contamination of the grains with harmful mycotoxins ... -
Validation and Use of Inertial Sensors to Assess Changes in Gait Stability Introduced by a Robot Companion
Inertial sensors have the potential to transform the field of human gait stability by enabling experiments to be conducted outside conventional laboratory conditions. New topics can potentially be explored, including ... -
Mapping waves with an uncrewed surface vessel via Gaussian process regression
(IEEE, 2023-05-29)Mobile robots are well suited for environmental surveys because they can travel to any area of interest and react to observations without the need for pre-existing infras- tructure or significant setup time. However, vehicle ... -
Microstructural characterization of the ζ- and γ-hydride phases in Zircaloy-2 by Electron Diffraction and Energy-Loss Spectroscopy Techniques.
In this study, the formation of the ζ- and γ-hydride phases in the form of independent bulk precipitates and interfacial ribbons between δ-precipitates and α-Zr matrix was investigated. Energy-Loss Spectroscopy (EELS) ... -
Changing the Landscape: A critical race informed narrative inquiry of a Canadian university told by Black, Indigenous, and People of Colour (BIPOC) students
The experiences of Black, Indigenous, and People of Colour (BIPOC) students in higher education are considerably different from the experiences of non-BIPOC students. We concluded that structural racism is deeply embedded ... -
Run-time Monitoring of a Rover: MDE Research with Open Source Software and Low-cost Hardware
(CEUR-WS, 2016)This paper is an experience report on how we conducted research in run-time model monitoring with Open Source Software (OSS) and low-cost hardware. We demonstrate our experience using a Rover system case study, where we ... -
Investigating the Role of Neuropeptide Receptor 14 (NPR-14) in C. elegans Sleep
Narcolepsy is a chronic sleep disorder that affects an estimated 1 in 2,000 people in the United States and Europe, making it one of the most prevalent sleep conditions worldwide (Longstreth et al., 2009; Silber et al., ... -
Modeling the Phase Response of an Optical Filter with Application to Cascaded Filtering in an Optical Link
To accurately characterize the effects of optical filters, it is crucial to model the filter's frequency response as precisely as possible. Given that the amplitude response of an optical filter can be obtained through ... -
Historical Review of Teacher Education in the Inuit Jurisdictions of Canada
(Unpublished, 2023-02-02)This report provides historical context for the development and offerings of teacher education programs serving Inuit communities in the four Inuit Nunangat (homelands) in Canada. From west to east, they are: Inuvialuit ... -
The Geochemical Evolution of Two High Arctic Lakes and the Recurrence of Elevated Bottom Water Conductivity
This study investigates the long-term physical and chemical changes in High Arctic lakes to understand the source of seasonally recurring elevated bottom water conductivity (EBWC) (in the bottom 0.5-2.0 m of the lake). To ... -
Underwater Surveillance Robot
(2023-03-03)Remotely operated underwater vehicles are used in a variety of industries for maintenance and transport, surveillance and inspection, and research and data collection. They allow for a more convenient and flexible option ... -
Resistor Sorter
(2023-03-01)An autonomous resistor sorter would be a valuable tool in physics labs, as it would save time and reduce errors incurred by manual sorting of resistors. This paper presents the design and development of such a device, with ... -
Designing and Testing a Smart Cat Feeder Prototype
(2023-03-01)This report describes the design process for a smart cat feeder. The main goals of the project include dispensing food on a user-set schedule, regularly weighing two cats and the food they eat, and making weight data easily ... -
The Culture Behind Writing: An Inquiry Into the Challenges and Cultural Influences on Second Language Writing in The Canadian Academic Context
The current number of international students in post-secondary education in Canada is 388,782, of which 39.4% are in colleges, and 60.5% are in universities (TEST, 2022). International students bring multiculturalism, ... -
Examining the Effects of Endothelial BMPR2 Loss on Angiogenesis in Murine Metastatic Lung Tumours
It is proposed that bone morphogenetic protein 9 (BMP9) may play a role in cancer development and tumour angiogenesis; however, its role has not been fully elucidated. Under normal conditions, BMP9 acts as a vascular ... -
Computing vibrational spectra using a new collocation method with a pruned basis and more points than basis functions: avoiding quadrature
(2023-02-14)We present a new collocation method for computing the vibrational spectrum of a polyatomic molecule. Some form of quadrature or collocation is necessary when the potential energy surface does not have a simple form that ... -
Anion Effect on CO2 Electrochemical Reduction on Cu
As cost of renewable energies continues to decrease, CO2 electrochemical reduction (CER) to value added fuels and chemicals is now a foreseeable possibility. Multi-carbon (C2+) products, such as ethanol and ethylene are ...
