Assessing factors contributing to the changes in historical temperature extremes and investigating future changes in extreme events
(Faculty of Graduate Studies and Research, University of Regina, 2022-07)Temperature extremes are among the most studied features in the climate research community using both the observed datasets and the simulated outputs from climate models. Such extremes often lead to irreversible societal, ... -
Assessment of Greenhouse Gas Emissions From Spring Wheat Cropping System in Saskatchewan
(Faculty of Graduate Studies and Research, University of Regina, 2019-04)The assessment of GHG emissions from spring wheat cropping system in Saskatchewan was conducted in this study. A general emission assessment model was developed. The main sources of GHG included emissions from farming ... -
Complexity Parameters for Learning Multi-Label Concept Classes,
(Faculty of Graduate Studies and Research, University of Regina, 2015-03)In Computational Learning Theory, one way to model a concept is to consider it as a member of the Cartesian products of instances (sets), where each instance may correspond to a binary or multi-valued domain. A concept ... -
Conditional Preference Networks: Constraints, Genuine Decision, and Aggregation
(Faculty of Graduate Studies and Research, University of Regina, 2020-01)A Conditional Preference Network (CP-net) graphically represents user's conditional ceteris paribus (all else being equal) preference statements, while a Tradeoffs enhanced CP-net (TCP-net) extends the CP-net with ... -
Convergence and Comparison Theorems for Various Splittings of Matrices Based on Generalized Inverses
(Faculty of Graduate Studies and Research, University of Regina, 2015-03)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 ... -
Development of an Integrated Hydro-Climatic Systems Analysis Framework and its Application to the Athabasca River Basin, Canada
(Faculty of Graduate Studies and Research, University of Regina, 2016-09)Climate change has profound impacts on regional hydrological characteristics in large unregulated continental river basins (LUCRiBs) such as the Athabaasca River Basin (ARB), Canada. A systematic analysis of these impacts ... -
Development of GHG-Mitigation Oriented Models for the Planning of Integrated Energy-Environment Systems (IEES) Under Uncertainties
(Faculty of Graduate Studies and Research, University of Regina, 2013-08)Energy-related activities are a major contributor of anthropogenic greenhouse gas (GHG) emissions. The mitigation of GHG emissions should thus be incorporated within the framework of integrated energy-environment systems ... -
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 ... -
Disaggregated Modeling of Environmental and Economic Systems of Supporting the Development of Greenhouse Gas Mitigation Policies
(Faculty of Graduate Studies and Research, University of Regina, 2019-08)Global climate change has emerged as one of the most challenging environmental issues and has gained considerable attention worldwide. Greenhouse Gas (GHG) mitigation policies are needed to avoid the increasing risks of ... -
Distinguishing Linear Sets and Pattern Languages With Membership Examples
(Faculty of Graduate Studies and Research, University of Regina, 2017-09)In Computational Learning Theory, a binary concept is often represented by a set of pairs (x; l), where x varies over a set of instances known as a universe or instance space, and l is a label, either "+" or "-", indicating ... -
Emergency Evacuation Management for Nuclear Power Plant Accidents Under Multiple Uncertainties
(Faculty of Graduate Studies and Research, University of Regina, 2017-01)Nuclear power accidents are one of the most dangerous disasters posing a lethal threat to human health and have detrimental effects lasting for decades. Therefore, emergency evacuation is important to minimize injuries ... -
An Empirical Study on Sum-Product Networks Structure Learning and Deep Convolutional Sum-Product Networks
(Faculty of Graduate Studies and Research, University of Regina, 2020-01)Sum-product Networks (SPNs) are generative probabilistic models which obtained the attention of the community for its tractability and easy methods for learning. Our rst main contribution is an empirical comparison of ... -
The Erdős-Ko-Rado Theorem for Transitive Permutation Groups
(Faculty of Graduate Studies and Research, University of Regina, 2022-03)Given a transitive permutation group \(G \le Sym(\Omega)\), a subset \(F\) of \(G\) is \(\textit {intersecting}\) if any two elements of \(F\) agree on some elements of \(\Omega\). We are interested in the problem of finding ... -
A Graph-Theoretic View of Teaching
(Faculty of Graduate Studies and Research, University of Regina, 2012-07)In computational learning theory, concepts are subsets of a set of instances and a concept class is a set of concepts. In many computational learning models, learning algorithms have the goal to identify the target concept ... -
Handling Qualitative and Quantitative Preferences with Constraints in Interactive Applications
(Faculty of Graduate Studies and Research, University of Regina, 2017-03)Preference elicitation is very important for interactive systems. A potential buyer typically has speci c expectations in the attributes of the product he or she is interested in. While the current interactive systems ... -
Incorporating Three-Way Email Spam Filtering With Game-Theoretic Rough Sets
(Faculty of Graduate Studies and Research, University of Regina, 2019-02)Email spam filtering commonly is viewed as binary classification problem, that is, classifies incoming email messages into spam or non-spam email. But it has two main limitations. Firstly, binary classification needs ... -
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 ... -
Learning Erasing Pattern Languages from Minimal Information
(Faculty of Graduate Studies and Research, University of Regina, 2016-10)A pattern is a concatenation of variable symbols and constant symbols. The language of a pattern is the set of strings generated by replacing the variables of the pattern with all possible strings. Patterns and pattern ... -
Learning Pattern Languages from a Small Number of Helpfully Chosen Examples
(Faculty of Graduate Studies and Research, University of Regina, 2013-08)A pattern is a string containing variable symbols and constants. The language of a pattern is the set of all strings obtained by replacing all variables in the pattern with non-empty strings. Patterns and their languages ... -
