2015 — Convergence and Comparison Theorems for Various Splittings of Matrices Based on Generalized InversesRésumé
The convergence of iterative methods for numerically solving the linear systems of equations associated with different types of splittings has been well studied in the literature. In this dissertation, we define new types of splittings based on generalized inverses (Moore-Penrose inverse, Drazin inverse, Group inverse) and present convergence results based on those splittings, namely, Weak Nonnegative Proper Splitting, Proper Regular Splitting, Index Proper Regular Splitting, Weak Nonnegative Index Proper Splitting, Group Proper Regular Splitting, and Weak Nonnegative Group Proper Splitting. We also present some new comparison theorems between the spectral radii of matrices, which are useful in the analysis of … Lire la suite

2015 — Terrorism Turned Monstrous: An Examination of Post-9/11 Science-Fiction-Horror Films Adapted from Pre-9/11 Source TextsRésumé
This thesis explores three post-9/11 film adaptations, War of the Worlds (2005), I Am Legend (2007), and The Mist (2007), in an attempt to better understand societal influences on the adaptation process by examining the alterations that a literary adaptation prepared to go to film undergoes in order to suit a contemporary audience. The ways in which we negotiate cultural trauma are not direct and it may take time and mediation in order for the trauma to be healed. This thesis argues that mediation of the cultural trauma associated with 9/11 is directly connected to Hollywood blockbuster science fiction and … Lire la suite

2015 — Studies on Syntheses of 1-Azaspirocycles, 2,6-Disubstituted 3-Piperidinols and cls-DecahydroquinolinesRésumé
Pyrrolidines and piperidines bearing a nitrogen-substituted quaternary stereocenter are commonly encountered structural motifs in many naturally occurring alkaloids, and therefore development of methods for their synthesis are important. The Rh(II)-catalyzed intramolecular tertiary C-H insertion reaction of 5-(-diazoacetoxy)piperidin-2-ones and 3-(-diazoacetoxy)pyrrolidines carrying C6 and C2 alkyl substituents, respectively, was investigated for the formation of bicyclic lactones bearing a nitrogen-substituted quaternary stereocenter. Both Rh(II)-carboxylate and Rh(II)-carboxamidate catalysts with varying electronic and steric properties were examined; however, these reactions usually resulted in the formation of complex mixture of products and the desired tertiary CH insertion products were not formed. The steric interactions encountered by … Lire la suite

2015 — Purchasing Fear: Analyzing Cold War Ideologies in Alfred Hitchcock’s The BirdsRésumé
During the Cold War Americans were inundated with talk of atomic weapons, attacks, communist spies, and alleged “contamination.” It is a commonplace that films offered an escape from this repetitive flood of fear and indoctrination. However, upon examination, Alfred Hitchcock’s The Birds (1963) appears to have intensified Cold War fears and anxieties, rather than pacifying them. This thesis focuses on depictions of Cold War imagery represented in The Birds. The film’s imagery will be dissected and examined through semiotic analysis, in an attempt to expose the film’s Cold War imagery that threatened Americans and American ideals. While Hitchcock sought favorable … Lire la suite

2015 — “Nunca Compré un café”: Lived Experiences of international ESL Latino Students at the University of ReginaRésumé
This thesis explores lived experiences of ESL (English as a Second Language) Latino students at the University of Regina. The internationalization of higher education, a response to global changes, has brought new and numerous challenges to both ESL/international students as well as universities. Despite some annual fluctuations, Canada is among the top fifth of countries regarding international post-secondary enrolment. Therefore, Canadian universities are among the universities that need to adapt to numerous challenges that the internationalization of higher education brings. In light of these changes to Canadian universities, this qualitative study explores lived experiences of ESL (English as a Second … Lire la suite

2015 — Numerical Modeling of the Dam-Break on a Slope Channel by WC-MPS MethodRésumé
Numerical simulation methodologies have become a major approach for solving hydrodynamics problems over the past few decades. Due to their flexibility and adaptability, these methods can be employed in various subjects of engineering and science. These simulations are capable of providing the required knowledge to interpret the natural phenomena and as well can be an alternative means to study the theories and experiments. Numerical modeling of fluid flow can be categorized into two major approaches, mesh-based methods and mesh-free methods. Mesh-based methods used to be the dominant methods through the decades but their lack of success in the precise simulation … Lire la suite

2015 — Verses at the Burning of the World: Modernism as a Fulfillment of Decadent IdealsRésumé
This thesis studies the transition between Decadent and Modernist poetry in England. The general critical perspectives of the evolution between the fin-de-siècle poetry of the 1890s and the high-Modernist verse of the 1920s were either of too great a separation, or too much a continuation. This study suggests that the Decadents were in fact precursors of the Modernists in their attempts to both stylistically and substantively challenge the dominant modes of poetry, its publication, and its relationship with the reading public in the face of the continued and exponential growth of industrialization, urbanization, commercialization, and other perceived consequences of modernity. … Lire la suite

2015 — Leisure Spaces and leisure Constraints for Lesbian WomenRésumé
Researchers have argued that leisure and leisure spaces are gendered, differentiating men and women in their opportunities for and outcomes of leisure (e.g., Aitchison, 1999; Henderson & Shaw, 2006). Gender expectations generate leisure constraints especially for women (Shaw et al., 1991). Furthermore, within the female group, lesbians face additional constraints because of the intersection of sexism with homophobia (Pritchard et al., 2002; Taylor, 2007). In 2011, I conducted an online pilot study with a sample of 813 lesbians which suggested that for most participants, self-consciousness and fear of harassment prevented them from fully enjoying their leisure in public spaces. This … Lire la suite

2015 — Environmental, Social and Economic Impacts of the Changing Wastewater Regulatory Landscape and Engineering Design Requirements in CanadaRésumé
In 2009, the Federal Government established new regulations for municipal wastewater systems and encouraged the provinces and territories to take part and formally commit to meeting the new limits. Saskatchewan, along with other provinces and territories, agreed to incorporate the new standards into their provincial legislation by signing the Canada-Wide Strategy for the Management of Municipal Wastewater Effluent (the Strategy). This paper will review the current provincial wastewater effluent regulations in Saskatchewan and the changes that are being made to meet the requirements set out in the Strategy. The most significant changes are to reduce the concentration of nutrients that … Lire la suite

2015 — Assessing Value in Upstream Health Interventions: A Case Study of the Dr. Paul Schwann Centre Cardiac Rehabilitation ProgramRésumé
In the past several decades, a major ideological shift has occurred regarding the relative importance of broad socioeconomic factors as determinants of health over access to conventional health services. During this time, public health experts have continually re-emphasized the need to focus attention further “upstream” of disease, in order to prevent populations from developing poor health. While provincial health systems currently integrate some population and public health programming within the basket of services they offer, upstream health interventions represent only a very small proportion. While many factors can explain this pattern, one explanation is key; upstream health interventions must compete … Lire la suite

2015 — Narratives of Aboriginal Grandmothers: Stories of Identity and HealthRésumé
In recent years, researchers have been exploring the significance of identity and its relation to overall health within Aboriginal communities (Bourassa & Peach, 2009; Carriere, 2005; Mikkonen & Raphael, 2010; Wilson, 2004). Aboriginal identity is central to the health and understanding of oneself and has been recognized by researchers as a key determinant of health (Bourassa, McKay-McNabb, & Hampton, 2009; Carriere, 2005; Mikkonen & Raphael, 2010; Wilson, 2004). There is a growing body of knowledge supporting this connection, yet there remains a shortage of work specifically related to Aboriginal grandmothers’ experiences and understandings of identity and health. Consequently, existing concepts … Lire la suite

2015 — Lives Disrupted: Resettlement Stories of Men Leaving War Torn CountriesRésumé
The purpose of this qualitative research study was to explore the lived experience of men who fled war torn countries and now reside in Regina, Saskatchewan, Canada. Drachman's (2008) Stages of Migration Framework was used to explore three stages of migration: pre-migration/departure, transit and resettlement. This qualitative research study used a narrative approach using Lieblich, Tuval-Mashiach and Zilber’s (1998) holistic content analysis to uncover the themes. Bronfenbrenner’s (1989) ecological theory was used to analyze and interpret the findings. Three participants were interviewed for this study and a total of seven themes were uncovered from the men’s narratives. In the pre-migration … Lire la suite

2015 — The Creation of Narrative Space: The Directional System of Upper TananaRésumé
This thesis shows how one portion of Upper Tanana Athabascan spatial language, the directionals, is used by storytellers to create detailed maps and descriptions of story settings. Additionally, this thesis also shows how the storytellers of Northway and Tetlin are able to use their intimate knowledge of the landscape to pick frames-of-reference and uses of directionals which are best suited to describe a narrative episode. That is, directionals may be used to both describe the immediate environment of a story—or the motion or orientation of objects in the surroundings—or to inform the audience of characters headings or locations throughout the … Lire la suite

2015 — Chloride Salts Removal by non Planted Constructed Wetlands Receiving Synthetic Brines from Belle Plaine Potash MiningRésumé
Four pilot-scale constructed wetlands (CWs) were employed to study the fate and transport of the two dominant chloride salts (NaCl and KCl) receiving the synthetic brine. The characteristics of the brine solution are made up with a 10:1 concentration ratio between NaCl and KCl based on data obtained from Belle Plaine potash mine site. The multi-layer soils were designed to function as a main salt filtering component comprising of Regina Clay (grain size <0.002 mm), Brick Sand (grain size <4.75 mm) and sharp gravels (grain size between 6.3-19.1 mm) despite the clay layers contained a poor compact condition (Db =1.4, <1.6 g/cm3). The volume of void space in the compacted clay was reduced to approximately half the natural state following application of pressure (4,505 cm3 to 2,743 cm3). The CW systems were operated by the 16-day format (batch 1-3) and the 4-day format (batch 4). During the 16-day format experiments, the best K+ removal rate was recorded on Cell2 as 92.1±63.4% (4.6±5.3mg/l) while Cell 4 contributed the maximum removal of Na+ and Cl- as 44.8±76.7% (53.2±92.4mg/l) and 50.5±109.6% (85.3±184.3.4mg/l). In the 4-day format operation, the chloride breakthrough curve was discovered in all treatment CW cells, excluding the control. Moreover, the curve stated at less than 6 hours (C/C0 > 0.05) and approximately reached the break point (C/C0 > 0.95) after passing 48 hours. Then the clay media was exhausted and lost its ability to remove Cl-. However, …</0.002> Lire la suite

2015 — The Role of The Saskatchewan Herald in the Construction and Extent of the “Siege of BattlefordRésumé
This thesis examines the role played by The Saskatchewan Herald in the construction of the circumstances that led to the 1885 Siege of Battleford. Generally discussed only as a peripheral event of the North-West Rebellion, the Siege of Battleford involved approximately five hundred men, women and children who congregated within the walls of a small North-West Mounted Police fort. Terrified of the intentions of their First Nations neighbours, the ‘siege’ lasted for more than a month and ended only with the arrival of Colonel William Dillon Otter’s column of the North-West Field Force. The self-protective action taken by the citizens … Lire la suite

2015 — The Effect of Knee Osteoarthritis on the Variability and Fractal Dynamics of Human GaitRésumé
Knee osteoarthritis (OA) is the most common joint disease seen in the older adult population, and has a greater influence on gait compared to the effects of aging alone. Spatiotemporal parameters can be used to quantify age-related changes in gait, however gait variability (i.e., the magnitude of stride-to-stride fluctuations with respect to time) and the fractal-scaling index (FSI) (i.e., correlated self-similar patterns of gait) can provide better information about the rhythmicity of the gait cycle over time. Recent studies have shown a relationship between knee OA and gait variability for certain spatiotemporal parameters, but the evidence is still preliminary and … Lire la suite

2015 — The Hahn-Banach Separation Theorem in Free ConvexityRésumé
This thesis presents and develops theorems on separation in the context of free convexity and matrix convex sets. After presenting a proof of the Hahn-Banach Separation Theorem, the main work in this thesis is a treatment of the Effros-Winkler Hahn-Banach Separation Theorem in the setting of matrix convex sets. This result is subsequently interpreted as a theorem concerning noncommutative sets in free analysis. Lastly, a new and complete characterization (in terms of liner pencils) of the matrix convex hull of a g-tuple of complex matrices is established. Lire la suite

2015 — High Resolution Visual Pipe Characterization System Using an Omnidirectional CameraRésumé
Machine vision techniques are applied in a wide variety of industries around the world for quality inspection of the products. One area that is getting a signi cant amount of attention is pipelines. Pipe manufacturers strive to do fast and reliable quality control. Furthermore, pipeline users are justly concerned about the sustainability of their aging infrastructure. Timely pro-active inspection is, therefore, paramount in balancing maintenance cost over time. Omnidirectional imaging systems are gaining world-wide attention due to their cost e ectiveness, fast calibration, and size factor. However, due to their high distortion, they are rarely used for pipe inspection applications. … Lire la suite

2015 — Three-Way Classification ModelsRésumé
In 1982, Pawlak proposed a theory of rough sets for data analysis. A fundamental concept of rough sets is the approximation of a set by a pair of lower and upper approximations or three pair-wise disjoint positive, negative and boundary regions. In 1990, Yao et al. introduced a probabilistic version called decision-theoretic rough sets (DTRS). Motivated by a three-way interpretation of the probabilistic positive, negative and boundary regions, in 2012 Yao proposed a theory of three-way decisions based on the actions of acceptance, rejection and non-commitment. The theory pro- vides a uni ed framework that integrates rough sets, interval sets, … Lire la suite

2015 — “Citizenship and the Emergence of the Antigonish Movement in Maritime Canada”Résumé
Canadians exited World War I with a new hope for their relationship with the state. After four years of government control and intervention in their lives, citizens demanded increased state involvement in their welfare, an expectation that became more pronounced during and following the Great Depression. Coupled with these increased demands on the state, there was a changed notion of citizenship that looked to increased protection by government of the basic social, political and legal rights of all citizens. Those new notions of citizenship and the role of the state helped to shape the Maritime co-operative movement that emerged most … Lire la suite

2015 — Stereotypes and Perceptions of Child Witness CredibilityRésumé
Research has examined factors that influence child witness credibility because it has the potential to influence case outcomes. This study investigated beliefs that impact perceptions of child witness credibility in cases of physical abuse. Participants (N = 95) were asked open ended questions inquiring about factors that either contribute to or detract from credibility. Using the responses provided, a check-list was created to assess the strength of the association between the words generated and the categories (i.e., credible and not credible; N = 64). The second part of this study examined whether a training protocol could ameliorate belief activation and … Lire la suite

2015 — An Evaluation of Some Robust Estimators of Regression CoefficientsRésumé
In the theory of regression analysis, the method of least squares is most commonly used because of its mathematical beauty and computational simplicity. However, this method is now criticized more and more because it often has very poor performance when there are outliers in the data. In this connection a variety of robust statistics are developed for that they are not unduly a ected by outliers. In this thesis comparison studies have been made for several robust statistics to see which performs better than the others. Monte Carlo simulation has been used to carry out the comparison of these statistics, … Lire la suite

2015 — Resource Use and Ecological Population Structure of Lake Whitefish (Coregonus clupeaformis) Spawning Aggregations in Lake HuronRésumé
Lake Whitefish are a commercially and ecologically valuable freshwater species in Lake Huron. Recent environmental changes have had broad impacts on current populations, which threaten the sustainability of this fishery. To properly conserve this resource, multiple sub-populations in the lake must be adequately represented in management regimes. Of special importance are adult spawning aggregations, which collectively contribute to the productivity of the fishery. However, spawning aggregations in Lake Huron are perceived to represent multiple stocks, adding complexity to fisheries management. The current population structure for adult Lake Whitefish is not well understood at the lake wide scale, and previous assessments … Lire la suite

2015 — Produced Water Treatment by Organoclay Adsorption and Dissolved Air FloatationRésumé
Global demand of energy is increasing due to population growth and industrial development. There will be an increase of 56 % in energy consumption between 2010 and 2040 from 524 quadrillion Btu to 630 quadrillion Btu (IEO, 2013). However the production process generates a large quantity of produced water (PW) which consists also of toxic, persistent and carcinogenic constituents. In this research, organoclay adsorption in stirred tank was integrated with Dissolved Air Floatation (DAF) for the treatment of synthetic produced water. Experiments were divided into four sections: Control Experiments (only DAF), Screening Experiments (Screening of OC from Jenfitch LLC, Ecologix … Lire la suite

2015 — Trajectory Planning for Hyper-Redundant Manipulators in Constrained WorkspacesRésumé
Trajectory planning for robotic manipulators is defined as the process of breaking down an arbitrary movement task into discrete motions while satisfying movement constraints and optimizing a cost function. Rapid advances in robotics technology recently have resulted in increasing applications of vast variety types of robot manipulators. In spite of the fact that various aspects of trajectory planning for robot arms have been investigated, the problem of quickly planning a collision avoiding path for hyper-redundant manipulators in cluttered environments, has not been intensely addressed. This research has developed a comprehensive computationally tractable collision free path planner for robot manipulators with … Lire la suite

2015 — Uncertainty Quantification of Hydrologic Predictions and Risk AnalysisRésumé
Hydrologic models are designed to simulate the rainfall-runoff processes through conceptualizing and aggregating the complex, spatially distributed and highly interrelated water, energy, and vegetation processes in a watershed into relatively simple mathematical equations. A significant consequence of process conceptualization is that the model parameters exhibit extensive uncertainties, leading to significant uncertainty in hydrologic forecasts. Consequently, to facilitate more reliable probabilistic hydrologic predictions and multivariate hydrologic risk analysis, innovative uncertainty quantification approaches are desired in order to reveal the inherent uncertainty in hydrologic models. Water is the life-giving resource required by all species on our planet and is the integral link … Lire la suite

2015 — Becoming a Critical Literacy Educator: A Self- Study of Unlearning and RelearningRésumé
The purpose of this research is to explore how critical literacy can be used as part of an anti-oppressive pedagogical approach. This paper will use self-study as the research methodology along with poststructural theory to analyze the roots of my understanding of critical literacy and how my positioning as a white, Christian, female, middle-class educator pushes against a critical orientation. Throughout the study, I will identify places of tension and resistance that come from resignifying my identity as an anti-oppressive educator within an education system rooted in rational, positivist ideologies and dominant practices. The research conducted focuses on dominant ideologies … Lire la suite

2015 — A Randomized Controlled Trial of Internet-Delivered Cognitive Behaviour Therapy for Individuals with FibromyalgiaRésumé
Fibromyalgia (FM) is a condition that affects approximately 1,050,000 Canadians. Symptoms of depression and/or anxiety are present in up to three quarters of individuals with FM. A large percentage of individuals with FM, however, fail to seek psychological treatment for these symptoms, suggesting the need for the development of more accessible treatment methods, such as Internet-delivered cognitive behaviour therapy (ICBT). There has been limited research on the use of ICBT for FM and no research within the Canadian context. The focus of the current study was to assess the efficacy of the Pain Course, an ICBT program originally developed for … Lire la suite

2015 — Improvements and enhancements of mps in free surface flow simulation.Résumé
The grid-based Eulerian methods have dominated the CFD (Computational Fluid Dynamics) for decades due to its simplicity. The grids not only used for discretize the simulation domain but also used for the computation, however, due to the inherent disadvantages of the grid-based Eulerian method, the free surface flow cannot be simulated successfully without special numerical techniques. Recently, another numerical approach has been developed for hydraulic simulation, namely, the particlebased Lagrangian approach. In this approach, the domain discretization as well as the simulation procedure differs from traditional Eulerian approach. gridless methods are typical Lagrangian based method, the basic simulation elements used … Lire la suite

2015 — A Voxel-Based Approach to the Real-Time Simulation of Sands and SoilsRésumé
Natural terrains composed of sands, soils, and other types of granular materials are subject to deformation and alteration when in uenced by interactions with humans and machines. These interactions include excavation and earthmoving activities such as digging, pushing, lifting, dumping, and piling. Simulating the deformation of sand and soil- lled terrains in interactive computer graphics applications is challenging due to the ne-grained and highly dynamic nature of these materials. In this thesis, we present the theoretical background, algorithms, and implementation details for a voxel-based terrain rendering system that simulates large, dynamic bodies of sands and soils in real-time 3D graphics … Lire la suite

2015 — Recovery from Deliberate Self-Harm: Perspectives from Those Who Have Survived and From Those Who Have HelpedRésumé
Interventions for adolescents who engage in deliberate self-harm are notoriously challenging and negligibly effective. Self-harming adolescents often keep their behaviours a secret, do not see their self-harm as a problem, and rely heavily on parents and friends for support and assistance in help-seeking. In fact, social support, particularly via friends and family members, has been identified as one of the most crucial components to self-harm recovery. Although parents and friends are vital to help-seeking and recovery, little is known about the lived experience of parents and friends in supporting someone who self-harms. What little is known indicates that parents and … Lire la suite

2015 — Building Social Capital Through Sport, Culture and Recreation: An Experiment in Collaborative Governance in Saskatchewan Using The Proceeds of State-Directed GamblingRésumé
When states make the decision to increase government revenue from gambling, they have to mediate between a range of options for operating, regulating and controlling an industry viewed by many people to produce more public harm than benefits. Very little research has been conducted that explores the interface between the generation of revenue from state-directed gambling and efforts that governments make to use this revenue source for a social purpose. This study addresses this gap by exploring the choices available to governments for how to use gambling revenue. Cross-national comparative research reveals that the Canadian province of Saskatchewan is the … Lire la suite

2015 — How Spirituality Training impacts the Practice of Social Workers Assisting Elderly Clients in End-of-Live Care: A Hermeneutical Phenomenological ApproachRésumé
Social workers in end-of-life care settings are presented with many challenges. They are not only confronted by the common stressors associated with death and dying, but also with the existential concerns of the patients and their families. Social workers typically outnumber spiritual advisors or chaplains in a hospice palliative care unit, and therefore have more frequent exposure to these needs of the patients. As an elderly patient, in particular, approaches end-of-life, the notions of religion and spirituality can take on a more significant role in acceptance of mortality. Social workers have reported reluctance in addressing the spiritual matters of their … Lire la suite

2015 — Water- and CO2-Based Oil Recovery Processes in the Tight Main Pay Zone and Vuggy Residual Oil ZoneRésumé
In this thesis, water- and CO2-based flooding processes in the upper tight main pay zone (MPZ) and in the lower vuggy residual oil zone (ROZ) of a carbonate light oil reservoir were studied and compared. In particular, the oil recovery performance of miscible CO2 simultaneous water-and-gas (CO2-SWAG) injection in the tight Bakken formation was experimentally examined. More specifically, first, several carbonate reservoir rock samples from the MPZ and ROZ in the Steelman oilfield (Canada) were characterized by using thin-section analysis and X-ray diffraction (XRD). Second, the minimum miscibility pressure (MMP) between the light crude oil and CO2 at the actual … Lire la suite

2015 — Optimum Water-Alternating-Gas (CO2-WAG) Injection in the Bakken FormationRésumé
In this thesis, miscible CO2 water-alternating-gas (CO2-WAG) injection in the tight Bakken formation and the effectiveness of CO2-enhanced oil recovery (CO2-EOR) methods in the fractured Bakken formation were experimentally studied. First, the saturation pressure Psat, oil-swelling factor (SF), oil density, and CO2 solubility of CO2-saturated Bakken light crude oil were measured by using a PVT system. Second, the viscosities of CO2-saturated Bakken light crude oils with different CO2 concentrations were measured by using a capillary viscometer. Third, the vanishing interfacial tension (VIT) technique was applied to determine the minimum miscibility pressure (MMP) of the Bakken light crude oil and CO2 … Lire la suite

2015 — Framing Effects in Officer Use-of- Force Decision MakingRésumé
Framing research demonstrates that making simple changes to the description of a task or task strategy can affect behaviour in a number of contexts (Almashat, Ayotte, Edelstein, & Margrett, 2008), but to my knowledge they have not been examined in a law enforcement setting. The present research examines officer decision-making processes during an emergency situation by investigating the influence of framing effects on the use of force. An interactive video-based use-of-force simulation scenario represented the emergency situation and participants were presented with one of three preceding framing manipulations. The experimental conditions emphasized either upholding public safety (i.e., avoiding unnecessary/excessive force) … Lire la suite

2015 — Hexagonal Cylindrical Lattices: A Unified Helical Structure in 3D Pitch Space for Mapping Flat Musical IsomorphismRésumé
An isomorphic keyboard layout is an arrangement of notes of a scale such that any musical construct has the same shape regardless of the root note. The mathematics of some speci c isomorphisms have been explored since the 1700s, however, only recently has a general theory of isomorphisms been developed such that any set of musical intervals can be used to generate a valid layout. These layouts have been implemented in the design of electronic musical instruments and software applications. This thesis presents a new extension to the theory of isomorphic layouts, taking advantage of the repetition of notes in … Lire la suite

2015 — Optimization of CO2 Flooding Strategy to Enhance Heavy Oil RecoveryRésumé
Heavy oil is a significant energy resource around the world. In Canada, there are tremendous heavy oil reserves lying in the north of the provinces of Alberta and Saskatchewan. The key point for heavy oil recovery is to increase the mobility of heavy oil in the reservoir condition. The most effective methods of heavy oil recovery are thermal methods such as steam flooding, cyclic steam stimulation (CSS), steam-assisted gravity drainage (SAGD) and in-situ combustion for the great heavy oil viscosity reduction by heat. However, thermal methods are proving to be unsuitable for most of the heavy oil reservoirs in Canada … Lire la suite

2015 — Localization with the EnKF for the Automatic History Matching of the SAGD ProcessesRésumé
The Ensemble Kalman Filter (EnKF) has been successfully applied to data assimilation in Steam Assisted Gravity Drainage (SAGD) processes, but applications of localization for the EnKF in SAGD processes have not been studied. Distance-based localization has been reported to be very efficient for assimilation of large amounts of independent data with a small ensemble in water flooding processes, but it is not applicable to SAGD processes, since in SAGD processes oil is produced mainly from the transition zone from steam chamber to cold oil instead of the regions around the producer. As the transition zone could be identified by saturation … Lire la suite

2015 — Tunable Microwave Bandpass Filter Design Using The Sequential MethodRésumé
Microwave filers are the essential components in a RF (radio frequency)/Microwave system, because they are used to provide frequency selectivity. A RF/Microwave system always supports multiple radio frequency bands. Thus, several microwave filters are normally needed in a RF/Microwave system. The more microwave filters a RF/Microwave system will need, the more cost and lager physical sizes the RF/Microwave system will have. Thus, tunable microwave filters provide the possibility to extensively reduce the cost and physical size of a RF/Microwave system. During the last several decades, tunable microwave filters have attracted lots of research efforts. Conventional methods used to design tunable … Lire la suite

2015 — Mental Health Deterioration Among Western Canadian Post-Secondary Students: An Analysis of the Contextual Stressors and Obstacles to Utilizing Effective Coping MechanismsRésumé
Symptoms consistent with mental disorders such as anxiety and depression have reportedly increased both in prevalence and in severity among North American post-secondary student populations over the past several years. The present study examines undergraduate students’ self-reported symptoms consistent with two common mental disorders in a Canadian context, and sheds light on several factors hypothesized to predict students’ mental health outcomes, including perceived contextual stressors within the academic setting, attitudes towards and use of coping mechanisms, and perceived barriers to seeking treatment. The ultimate goal of this study is not only to examine the unique contribution of each set of … Lire la suite
