NMR Analysis of Various Amine-CO2-H2O Systems Interactions for Studies of Vapour-Liquid Equilibrium and Catalyst Aided and Unaided Solvent Regeneration
(Faculty of Graduate Studies and Research, University of Regina, 2013-12)The removal of CO2 by chemical absorption and regeneration has been researched for decades. CO2-amine interactions in solvent chemistry have been studied via the Vapour-Liquid Equilibrium (VLE) model. Databases for VLE ... -
Agent Trust Management Based on Human Plausible Reasoning and Rough Sets: Application to Agent-based Web search
(Faculty of Graduate Studies and Research, University of Regina, 2013-12)Nowadays, there is a growing need to manage trust in open systems. Service providers can autonomously join and leave the open system at any time. Thus, an open system may contain untrustworthy service providers. In order ... -
Quantum-Mechanical and Thermodynamic Study of Amines and Ionic Liquids for CO2 Capture
(Faculty of Graduate Studies and Research, University of Regina, 2013-12)There is worldwide interest to develop improved CO2-capture solvents to help reduce cost of capture and environmental footprint. This thesis aims to contribute to this goal by studying computationally and experimentally ... -
Mapping Predictive Ambient Concentration Distribution of Particulate Matter and Sulfur Dioxide for Air Quality Monitoring Using Remote Sensing
(Faculty of Graduate Studies and Research, University of Regina, 2013-12)Particulate matter (PM) and sulfur dioxide (SO2) are harmful to human health, especially at exposure levels of 30 μg/m3 of PM and 150 μg/m3 of SO2 for 24 hours. Agriculture and transportation are primary sources of PM ... -
Characterization of Streptococcus pyogenes and Staphylococcus aureus associated with mixed skin and soft tissue infections in northern Saskatchewan communities
(Faculty of Graduate Studies and Research, University of Regina, 2013-12)Community-associated infections are a significant public health concern worldwide. In particular, epidemic and emerging antibiotic-resistant bacteria associated with skin and soft tissue infections (SSTI) are becoming more ... -
A Randomized Controlled Trial of a Therapist- Assisted Internet Cognitive Behaviour Therapy Program for Women with Postpartum Depression
(Faculty of Graduate Studies and Research, University of Regina, 2014-01)Postpartum depression (PPD) impacts up to 15% of Canadian women following childbirth. The debilitating disorder not only impacts the woman, but also is related to short- and long-term consequences of her infant‘s ... -
AHP-Based Methodology for a Complex Decision Support in Extreme Programming
(Faculty of Graduate Studies and Research, University of Regina, 2014-01)Extreme Programming (XP) is one of the most successful methods in software development. It offers a set of practices designed to work together in order to provide value to the customer. The XP process emphasizes simplicity, ... -
Enhanced Solvent Vapour Extraction processes in Thin Heavy Oil Reservoirs
(Faculty of Graduate Studies and Research, University of Regina, 2014-01)Solvent-based techniques, such as solvent vapour extraction (VAPEX) and cyclic solvent injection (CSI), have emerged as promising processes to enhance heavy oil recovery. However, there are still a number of technical ... -
Saskatchewan Town Hall Opera Houses and Community Performance (ca. 1883-1913)
(Faculty of Graduate Studies and Research, University of Regina, 2014-02)The construction of public spaces is just one mechanism by which a community builds and continually negotiates the idea, or mythos, of its identity. Communities, through their dominant groups (including economic, social, ... -
Inexact Fractional Optimization for Multicriteria Resources and Environmental Management Under Uncertainty
(Faculty of Graduate Studies and Research, University of Regina, 2014-03)A set of inexact-fuzzy nonlinear programming (IFNP) and inexact fractional mathematical programming (IFMP) methods have been developed for the first time for supporting multi-criteria resources and environmental management ... -
Living a Curriculum of Tensions: Experiences of Learning to Teach Physical Education
(Faculty of Graduate Studies and Research, University of Regina, 2014-03)This narrative inquiry explored two pre-service teachers’ experiences of learning to teach Physical Education during a 16-week internship. My interest emerged from my experiences as a student, pre-service teacher, teacher, ... -
Development of Inexact T2 Fuzzy Optimization Approaches for Supporting Energy and Environmental Systems Planning Under Uncertainty
(Faculty of Graduate Studies and Research, University of Regina, 2014-04)With the increase and expansion of environmental requirements and dwindling of fossil fuel resources, current environmental and energy systems have aroused wide public concern. In this dissertation research, several ... -
A Rough Set Approach to Face Recognition
(Faculty of Graduate Studies and Research, University of Regina, 2014-04)Rough decision tables were originally proposed by Pawlak. The hierarchies of probabilistic decision tables (the hierarchies), defined in the context of Variable Precision Rough Set Theory (VPRS model), generalized this ... -
Unified Approach to Partially Linear Model and Cox Proportional Hazards Model with Missing Covariates
(Faculty of Graduate Studies and Research, University of Regina, 2014-04)In regression analysis the problem of missing covariate data is common in various fields of application. Many methods have been developed to deal with this problem in the past three decades. These methods are workable ... -
Synthesis and Reactivity of Functionalized Electrophilic Phosphinidene Complexes
(Faculty of Graduate Studies and Research, University of Regina, 2014-04)Electrophilic phosphinidene complexes play an important role in organophosphorus synthesis. The chemistry of neutral phosphinidene complexes has been well studied, but cationic phosphinidene complexes are not as well ... -
