2024 — From gee to haw (and everything in between): Deconstructing the transspecies pidgin of mushing in northern SaskatchewanRésumé
This multispecies ethnography deconstructs the Gee Haw transspecies pidgin of settler origin mushing in Northern Saskatchewan, Canada. Through a focus on multisensory methodological inquiry, I describe interspecies communication and human perceptions around nonhuman knowledge in the context of sled dog racing. This pidgin is a product of biconstructivism which includes motherese (verbal) words rooted in the English language, vocalisation, short phrases for reinforcement, the use of material devices, and training methodologies to shape a multisensory experience of interspecies collaboration. Dogs are considered nonhuman athletes in this hybrid community. They are bred, cared and trained for their “drive”, speed, endurance and … Lire la suite

2023 — Explorations of the lived experiences and needs of individuals with adult-diagnosed Cystic FibrosisRésumé
Cystic Fibrosis (CF) is a genetic, multisystem disease (Elborn, 2016) that can be diagnosed in both childhood and adulthood. Diagnosis of CF during childhood is well-documented in the literature, and there is substantial information available for the parents of children with CF (Edwards et al., 2018). However, those with adult-diagnosed CF have highlighted that the supplied information tends to be targeted towards parents of children with CF, brief in nature, dated, and geographically limited (Widerman, 2002; Widerman, 2004). The current study examined the lived experiences and needs for individuals with adult-diagnosed CF. Participants (n = 17) included eight individuals diagnosed … Lire la suite

2024 — Mathematical modeling and simulation of the performance of potassium glycinate in CO2 absorption in a packed-bed absorption columnRésumé
The aim of this research undertaking was to develop a mathematical model representation for the capture of CO2 using potassium glycinate as the absorption solvent. To this end, the study was subdivided into three major parts each designed to generate the requisite data for the subsequent stage. The three major parts of the study included the development of industrial process simulation to ascertain the emission data and characteristics of flue gas emanating from different industrial processes. The main processes under study were, Power Generation with particular emphasis on the Combined Cycle Gas Turbine setup, Natural Gas Pre-treatment, where the simulations … Lire la suite

2020 — Biological Treatment of Reclamation of Industrial Wasterwater From Post-Combustion Carbon CaptureRésumé
Carbon capture and storage (CCS) system is a technology that has been developed to reduce the carbon emission in carbon-intensive industries. Although CCS is a sustainable option for power plants, it still produces contaminants in the form of its wastewater stream. The CCS wastewater contains several contaminants that could affect both environmental and human health. This study will focus on the biological treatment of two contaminants: amines and sulfates. The main objective of this study is to design and develop an effective biological system to treat CCS wastewater to a quality that can be recycled back to the CCS process … Lire la suite

2019 — Quantification of Mutual Mass Transfer of Gas-Light Oil Systems at High Pressures and Elevated TemperaturesRésumé
Numerous tight oil resources that are characterized by both low porosity and permeability have been found in North America during past decades. Due to the extremely low permeability, water injection has found its limitation with its relatively low injectivity. Alternatively, gas injection, such as CO2, N2, hydrocarbon gas, and flue gas, has been made physically possible for enhancing oil recovery under certain conditions, during which molecular diffusion is of great importance. Due to the affordability and sustainability of CO2, N2 and flue gas have been found to be costeffective for enhancing hydrocarbon recovery to a certain extent. Physically, there exists … Lire la suite

2024 — Quantification of dissolution and exsolution dynamics of gaseous solvents in crude oil systems under reservoir conditionsRésumé
With a growing demand for fossil fuels, it is of a great importance to improve the oil recovery factor from both conventional and unconventional reservoirs. Among different enhanced oil recovery (EOR) methods, injecting gaseous solvents, including CO2, N2, flue gas, and alkane solvents, is considered as a more effective and efficient method in both light and heavy oil reservoirs, during which mass transfer is the key underlying recovery mechanism. In order to optimize the solvent injection method and achieve a higher oil recovery, it is of fundamental and practical importance to quantify both dissolution and exsolution dynamics of solvents in … Lire la suite

2023 — The influence of embryo incubation temperature on later life aerobic performance of Lake Whitefish (Coregonus clupeaformis) and Yellow Perch (Perca flavescens)Résumé
Temperature represents one of the most influential abiotic factors affecting all living organisms. Ectotherms, including fish, can be affected by temperature at the cellular, individual, population, and community levels. In modern times, climate change and thermal pollution pose major threats as they threaten to elevate water temperatures, therefore limiting optimal thermal habitats and exposing species to suboptimal environmental conditions. While adult fish of many species have the capacity to avoid these thermally impacted areas, early life stages (i.e., embryonic, larval, and juvenile) are typically limited in mobility and lack the ability to avoid these areas. These early life stages are … Lire la suite

2016 — Simplifying D-Separation and M-Separation in Bayesian NetworksRésumé
Many di erent platforms, techniques, and concepts can be employed while modeling and reasoning with Bayesian networks (BNs). A problem domain is modeled initially as a directed acyclic graph (DAG), denoted B, and the strengths of relationships are quanti ed by conditional probability tables (CPTs). Testing whether two sets X and Z of variables are conditionally independent given another set Y of variables is fundamental to BN modeling and inference. There are two well-known methods, called d-separation and m-separation, for this task. The founder of BNs suggested d-separation as a method for testing independen- cies. The crux of the linear … Lire la suite

2020 — Optimizing Inference in Bayesian Networks: From Join Tree Propagation to Deep LearningRésumé
Many di erent platforms, techniques, and concepts can be employed while modelling and reasoning with Bayesian networks (BNs). A problem domain is modelled initially as a directed acyclic graph (DAG) and the strengths of relationships are quanti ed by conditional probability tables (CPTs). We consider four perspectives to BN inference. First, a central task in discrete BN inference is to determine those variables relevant to answer a given query. Two linear algorithms for this task explore the possibly relevant and active parts of a BN, respectively. We empirically compare these two methods along with a variation of each. Second, we … Lire la suite

2022 — Human dignity and intellectual disability: Thinking with Beauvoir over the influence of the Kantian viewRésumé
“Kant is generally taken to be the locus situ of the intimate connection between personhood, dignity, and autonomy” (Kittay and Carlson 2010, 4). In this thesis, I consider how the Kantian view of morality influenced the creation of a framework for our concepts and treatment of human dignity which contributes to the discrimination of people with intellectual disabilities. I will argue that we need to conceptualize human dignity outside of a framework of autonomous agency because it becomes exclusive of some people with intellectual disabilities. Guided by the thought of Simone de Beauvoir I attempt to formulate, instead, a phenomenological-existential … Lire la suite

2025 — The SHRIKE Experiments with poetic form and the ghazal through the lenses of surrealism and the gothicRésumé
The Shrike is a collection of poetry that draws on poetics and theory related to surrealism, the ghazal, the uncanny and the gothic to explore an interest in the boundaries, limitations and transformation that comes from experimenting with genre and form. The notion of the “antighazal” or “non-ghazal” is adopted and challenged by The Shrike and is used as a means for further poetic experimentation and to understand the capacity for change within the ghazal form. The difference between ghazals in English and ghazals in Urdu is also discussed in regards to the tradition and culture the ghazal finds itself … Lire la suite

2012 — Image Quality Assessment Using Level-of-DetailRésumé
Image quality assessment is a very challenging problem in image processing. Most image quality metrics are currently based on super cial variations in pixel values, perceptual models and structural changes. As well, most are full-reference metrics in which a corrupted image is compared with an \original" or \perfect" version of that image. In many practical settings, however, this \perfect" image is not available. At this time, no metric is able to genuinely replicate human perception of quality. This research therefore introduces a new image quality model, one that centers on level-of-detail. Furthermore, the proposed techniques operate without any \original" image, … Lire la suite

2012 — Dietary Niche and Foraging Ecology of a Generalist Predator, Double-Crested Cormorant (Phalacrocorax Auritus): Insight Using Stable IsotopesRésumé
The ability of predator populations to expand their ranges and adapt to new environments is often attributed to having a generalist dietary strategy, which is thought to be represented both at the population and individual level. Cormorants (Phalacrocorax spp.) are considered to be opportunistic generalists capable of using a wide variety of aquatic prey. This reputation is partially responsible for the global conflict between piscivorous cormorants and fish harvesters, which is one of the most widespread wildlife management issues in history. Despite the persistent belief that cormorants adversely affect economically important fish populations, relatively little is known about their trophic … Lire la suite

2016 — Exploring Therapist Behaviours in Therapist-Assisted Internet-Delivered Cognitive Behavioural Therapy for Generalized Anxiety Disorder: A Mixed Methods AnalysisRésumé
Empirical support for the use of Therapist-Assisted Internet-Delivered Cognitive Behavioural Therapy (TAICBT) for the treatment of generalized anxiety disorder (GAD) has been rapidly growing. Research has generally supported the inclusion of therapeutic guidance in TAICBT; however, the specific role of the internet therapist is yet to be well understood. The current study aimed to enhance understanding of the nature of therapistassistance by examining: 1) therapist behaviours in emails sent to clients treated with TAICBT for GAD and the extent to which these qualitatively overlap with behaviours described in face-to-face therapy; and 2) if therapist behaviours in the current study (using … Lire la suite

2016 — An Experimental Study of Carbon Dioxide Dissolution into a Light Crude OilRésumé
Carbon dioxide (CO2) dissolution into a heavy oil has been extensively investigated as an effective solvent-based enhanced heavy oil recovery method for several decades. However, fewer attempts have been made to study CO2 dissolution into a light crude oil mainly because of possible occurrence of density-driven natural convection in the CO2- saturated light crude oil phase. The primary objective of this thesis is to experimentally study the phase behaviour of a Bakken light crude oil‒CO2 system and the complex mass-transfer process of CO2 dissolution into the light crude oil. First, a series of PVT tests were conducted to measure CO2 … Lire la suite

2017 — Comparative Evaluation of the Performance of Synthetic Polymer and Biopolymer as a Means of Enhanced Oil Recovery MethodRésumé
After regular primary and secondary recovery treatments with ideal oil production no longer occur, enhanced oil recovery methods are introduced to produce the “leftover” oil in reservoir formations. Among the enhanced oil recovery (EOR) methods, polymer flooding is regarded as the most common and widely used treatment globally. By adding water-soluble high molecular weight polymers into water, viscous fluids This work aims to analyze the performance of two types of polymers as a means of EOR by comparing their rheological properties and laboratory 1D sandpack flooding studies. It compares the performance of these polymers against the performance of waterflooding as … Lire la suite

2017 — Experimental and Mathematical Studies of Cyclic Solvent Injection To Enhance Heavy Oil RecoveryRésumé
It has been suggested that Cyclic Solvent Injection (CSI) is a highly promising technique to recover heavy oil resources at which other recovery techniques are not economically or efficiently available. Therefore, it is necessary to conduct experimental and mathematical studies on the CSI for effective heavy oil recovery purposes. Experimental and data regression studies have been conducted to investigate the effects of the wormhole on the CSI. Nine tests were completed using three sand-pack physical models with different dimensions. Experimental results suggest that the oil production can be divided into two phases: solvent chamber rising phase and solvent chamber spreading … Lire la suite

2021 — Analysis of Changes Based on Three-Way DecisionRésumé
Three-way decision has been applied in the data analysis domain since it was pro- posed by Yao in 2010. Three-way classi cation and three-way clustering are typical combinations of traditional processing methods of data analysis and three-way deci- sion. They mainly focus on data classi cation with the three-way decision. According to data features, the methods divide all objects into three regions. Most of the time, three-way classi cation and three-way clustering focus on data features to classify or aggregate data in regions. They ignore the information that changes may lead to results or patterns of data in di erent … Lire la suite

2012 — Conceptually-Based Strategy Use Investigating Underlying Mechanisms and Development Across Adolescence and into Early AdulthoodRésumé
Researchers have used inversion and associativity problems (e.g., 2 × 8 ÷ 8, 3 + 19 − 17, respectively) to assess whether or not individuals have the conceptual understanding that addition and subtraction and multiplication and division are inverse operations (i.e., the inversion concept, Robinson & Ninowski, 2003; Starkey & Gelman, 1982) and whether or not they understand that numbers can be decomposed and recombined in various ways and still result in the same answer (i.e., the associativity concept, Canobi, Reeve, & Pattison, 1998; Robinson, Ninowski, & Gray, 2006). It is not known when the development of these two concepts … Lire la suite

2012 — Prairie Spirit: Medieval Revival Ecclesiastical Architecture in Saskatchewan, 1839 - 1913Résumé
Architecture is an excellent indicator of the society that produced it. Saskatchewan’s architecture, however, has not received sufficient analysis and there are some major gaps in its history. One of the greatest gaps concerns the medieval revival styles, the Gothic Revival and Romanesque Revival styles. These two styles became especially common in the province’s early religious architecture. Therefore, this analysis focuses on the use of medieval revival styles in ecclesiastical architecture from 1839 to 1913. The Anglican, Roman Catholic, Methodist, and Presbyterian Churches made use of these styles during Saskatchewan’s most competitive, optimistic, and challenging period. In some instances, these … Lire la suite

2013 — Towards Ethical Practice: A Narrative Self Study of Discourses in the Drama ClassroomRésumé
This self-study explores some of the subject positions that are negotiated, produced and reinforced through discourses that circulate in the high school drama classroom where I teach. By exploring my areas of discomfort in the classroom as well as my self-definition as a teacher, I expose many of the ways I affect and am affected by technologies of power and governmentality that operate within the school. Drawing on a number of self-study research methods, through an interrogation of my intellectual history as well as through careful reflection of my past experiences as an educator, I illuminate some of the discursive … Lire la suite

2012 — Effects of Endurance Exercise on Cerebral and Muscle OxygenationRésumé
It has been suggested that during exhaustive exercise both a central and peripheral mechanism of fatigue exists. Indeed, a central debate in the exercise science literature is the nature of fatigue that determines exercise performance under different conditions (Swart et al., 2009a). Hypoxia, for example, has a small but direct role on the cessation of exercise, specifically during endurance performances (Millet, Aubert, Favier, Busso, & Benoit, 2008; Secher, Seifert, & Van Lieshout, 2008). Numerous studies to date have provided new information related to the factors implicated in short-term high intensity exercise, while more studies of a longer nature (endurance time … Lire la suite

2023 — The many worlds of Liz JordanRésumé
My creative thesis, The Many Worlds of Liz Jordan, is an urban-portal fantasy about authors who travel to secondary worlds , experience stories 1 first-hand, and only then write them up as “fiction.” The work is influenced by a number of writers, such as Terry Pratchett, Neil Gaiman, and James Riley. Terry Pratchett’s Discworld novels influenced my world’s overall tone. The boundaries of his creation allow for incredible adventures but promise an ultimately hopeful conclusion and outlook, and I have attempted to do the same here. As a sensitive reader myself, it is important that Liz Jordan’s world not betray … Lire la suite

2022 — Using thermal imagery and changes in stem radius to assess water stress in two coniferous tree speciesRésumé
With a warming climate and greater evaporative demand, the functioning of forest ecosystems is increasingly affected by water limitation. Water stress has the potential to impact many forests globally with tree die-back, drought-related injury and increased chances of wildfire. To address the need for an innovative, non-invasive research approach to gather insight into a tree’s water stress status, I employed airborne thermal imagery from unmanned aerial vehicles as a new tool for measuring leaf temperatures. Higher canopy leaf temperatures (CLT) have been related to plant water stress when there is low soil moisture and high evaporative demand. In this thesis, … Lire la suite
