2016 — Petrographic, Fluid Inclusion, and Illite Geothermometry Analysis of the Rumpel Lake Drill Core, Athabasca Basin, Northern Saskatchewan, CanadaRésumé
The Athabasca Basin in northern Saskatchewan contains some of the world’s highest-grade unconformity-related uranium deposits, the genesis of which has been extensively explored in the literature. Constraints on the temperature, pressure, and composition of diagenetic fluids within the Athabasca Basin have mainly come from research conducted in uranium-mineralised areas, however, research conducted distally from known uranium mineralisation is relatively scarce. This study aims to provide a detailed data set on the temperature, pressure, and composition of diagenetic fluids using petrographic, fluid inclusion, and illite geothermometric methods on samples from the Rumpel Lake drill core, and to compare the results with … Lire la suite

2013 — Canadian Approaches to Arctic Foreign PolicyRésumé
Throughout the Cold War the Arctic was treated as an international ‘no man’s land’. The tension created by the proximity of the Soviet Union to the other Arctic states made the development of effective Arctic foreign policies within the Arctic states almost impossible. However, the end of the Cold War resulted in the opening of political space that enabled the ‘lesser’ Arctic states to begin to have influence in the region. The Arctic states began to work together to develop forums for international cooperation on issues that impacted the Arctic region as a whole. This cooperation began with the implementation … Lire la suite

2014 — The Performance of Realistic Simulation over Vehicular NetworksRésumé
Allowing a vehicle on road to communicate real-time information on speed, braking and lane changing activities with other vehicles can help avoid accidents and traffic congestion. Vehicular Ad-hoc Network (VANET) is a network that involves moving vehicles within certain range of distance to communicate with each other, thus forming a network. A VANET turns every participating vehicle into a wireless router or node that allows them to communicate with each other. Although, a VANET provides safety measures and improves traffic efficiency, they are highly expensive to be used by all vehicles on roads. Several VANET simulators have been developed to … Lire la suite

2012 — Procrustes: A Declarative Scene Modelling SystemRésumé
This thesis presents a floor planning and furniture layout system called Procrustes, that helps a user to place rooms and furniture in a virtual house. Scenes are generated by considering the user's partial scene description. The resulting floor plans and furniture arrangements can be used in video games to generate scenes that are not of prime importance to the games. We developed the Procrustes Declarative Scene Modelling (DSM) system to reduce the amount of user input compared to existing DSM systems. The name Procrustes is extracted from a Greek mythological character who placed people in an iron bed and ensured … Lire la suite

2012 — An Investigation of a Theoretical Zigbee-Based Border Crossing SystemRésumé
Excessive delays at border crossings threaten the mobility of people and trading of goods. The management of transportation infrastructure generally requires continuous and real-time monitoring, formulation, and dissemination of information and guidance to motorists and other parties. This thesis proposes and studies a theoretical border crossing system utilizing ZigBee-based wireless networks. ZigBee (IEEE Standard 802.15.4) is a low data rate, low power, wireless communication protocol that enables the spontaneous formation of ad hoc wireless networks. In this system, trucks traversing border crossings are equipped with ZigBee-based systems, which can send different types of information including, for example, (bio-)chemical hazards and … Lire la suite

2021 — Thermomechanical and Vibrational Fatigue Life Assessment of Railway WheelsRésumé
Rail wheel failures can lead to derailment of trains, cost lives and billions of dollars to the railway industry. Therefore, it is important to understand the failure behavior of critical components of the train, especially the ones which are exposed to extreme weather conditions. This understanding is much needed to develop effective risk management procedures. Most research studies in wheel fatigue life estimation did not account for structural, thermal and prestressed random vibrational loading as a coupled field. The present study develops an advanced numerical analysis methodology that incorporates real service conditions to calculate fatigue life. Firstly, a validation study … Lire la suite

2018 — Performance Evaluation of Condiments as Environmentally Friendly Corrosion Inhibitors for Amine-Based Carbon Dioxide Absorption ProcessRésumé
Corrosion of process equipment and piping in the amine-based carbon dioxide (CO2) absorption process causes considerable expenditures for maintenance and repair. The addition of effective corrosion inhibitors to the amine solutions is a common practice for corrosion mitigation. Despite their inhibition effectiveness, those corrosion inhibitors used in the amine-based CO2 absorption process are not environmentally friendly and require costly waste handling and disposal. To reduce such cost and prepare for more stringent environmental regulations for chemical uses and disposal, this work investigated the feasibility of using condiments as environmentally friendly corrosion inhibitors in the amine-based CO2 absorption process. In this … Lire la suite

2012 — Kinetics of Carbon Dioxide Absorption into Aqueous Solutions of4-(Diethylamino)-2-Butanol and Blended Monoethanolamine and 4-(Diethylamino)-2-ButanolRésumé
Recently, global warming and climate change problems have begun to receive attention globally. One of the urgent policies is to control greenhouse gas emissions to the atmosphere. Among the greenhouse gases, CO2 is considered to be a major contributor due to its abundance. The absorption of CO2 into chemical solvents is one of the mostpromising technologies for capturing CO2 due to its capability of handling large amounts of exhaust stream. One of the key parameters for this technology is to use effective solvents. A newly developed amino alcohol solvent, 4-(diethylamino)-2-butanol (DEAB), is now being considered as a promising alternative solvent … Lire la suite

2025 — Proportional hazards modelling for current lifetime dataRésumé
Current lifetime data represent a unique subset of length-biased data where only the times from the initiating event to the cross-section date are observed without follow-up. We propose an efficient estimation procedure to fit the semi-parametric proportional hazards model using current lifetime data. This estimation procedure is based on the EM algorithm which has two versions based on the support points of the non-parametric baseline hazard function. We apply the method to simulated data and Parkinson’s disease current lifetime data drawn from the Canadian-Open Parkinson Network (C-OPN). We estimate the effects of clinical and epidemiological covariates using the proportional hazards … Lire la suite

2022 — RuraliaRésumé
Ruralia is a collection of original lyric poetry written to explore the feelings of longing and displacement that underscore my relationship to my prairie home. The collection draws on contemporary poetics and theory related to nostalgia, the lyric, the liminal, and the uncanny to examine the speakers’ continued attempts to define and attain a sense of “home” amid recurring transition and loss. Read as a regionalist work, Ruralia best aligns with the contemporary post-prairie poetic movement, which is characterized, in part, by its urban settings, location-based anxiety, and an absence of pastoral landscapes typical of traditional prairie poetry.

2013 — Understanding Parental Self-efficacy in FathersRésumé
Parental self-efficacy (PSE) is a cognitive construct that can be defined broadly as an individual’s appraisal of his or her competence in the parental role. Researchers interested in child developmental outcomes have highlighted the important role that PSE plays in psychosocial child adjustment. Despite its importance, the PSE construct has been understudied in men. Given the enduring gendered nature of parenting, it seems likely that fathers’ PSE may differ from mothers’ PSE in important ways. This study was the first to develop and validate a self-report scale that assesses the PSE of fathers with preschool aged children. The research was … Lire la suite

2020 — Age Differences in Pain ResponsesRésumé
One in five Canadians report experiencing chronic pain, which is associated with numerous negative psychological and physical consequences (Schopflocher et al., 2011). Older adults are more likely to experience pain than younger people and the degree of pain-related interference increases with age (Thomas et al., 2004). This is concerning given that pain is routinely underassessed and undertreated in older persons (American Pain Foundation, 2008; Kaye et al., 2010; Lautenbacher, 2014; Malec & Shega, 2015). Researchers have found many age-related differences in pain responses, such as pain perception and reporting and attitudes toward pain (Gibson & Farrell, 2004; Gibson & Helme, … Lire la suite

2021 — Parkinson's Disease Classification, Monitoring and Optimization of Deep Brain StimulationRésumé
Parkinson's disease (PD) alters the brain's anatomy when dopamine releasing neurons die in basal ganglia neural pathways. The resulting alterations force synchronized neuronal activity in beta frequency components in subthalamic nucleus (STN). This synchronization affects the chaotic behavior of the brain activities, which induce motor related impairments in patient’s limbs. This can be seen in the electroencephalogram (EEG) signals of PD patients. Deep brain stimulation (DBS) is the therapy of choice in later stage of disease when the side-effects of medication supersede its benefits. In this research work, we utilize the relationship between chaotic systems and brain for the analysis … Lire la suite

2021 — Anti-candida and Anti-virulence Activity of Essential Oils and Their ComponentsRésumé
Candida albicans is one of the most common fungi associated with lifethreatening infections. Treatment of the associated infections is often ineffective in the light of resistance, and so there is an urgent need to discover novel antifungals. Rather than killing the fungal cells, which requires quite high specificity and can lead to the emergence of further resistance, inhibiting growth and virulence factors in fungal cells represents a good alternative for the development of new antifungal drugs. Recently, there has been a resurged interest in essential oils and their active components, in relation to their pharmacological properties. The primary objective of … Lire la suite

2022 — The Schurian association schemes associated with parabolic subgroups of Coxeter groupsRésumé
We determine all cases where double coset algebras of string Coxeter groups with respect to maximal parabolic subgroups have the involutive double coset property. For infinite affine string Coxeter groups, this property was only known to occur in the case of the vertex stabilizer for the types ˜C2 and ˜G 2, our new work adds the infinite Coxeter groups of type ˜Cn(n > 2) and ˜F4 to the list. Finite homomorphic images of these groups include the automorphism groups of abstract regular polytopes. An application of the above result is that polytopes of these types will always have polyhedral realization cones. … Lire la suite
