Modulation scheme investigation for high-power medium-voltage current source converter based drives
(2023)Pulse width modulated (PWM) current source converter (CSC) based drives are commonly used in high-power (1-10 MW), medium-voltage (MV) (2.3-6.6 kV) applications. These drives feature a simple converter structure, inherent ... -
A framework to avoid maloperation of transformer differential protection under geomagnetic disturbances
(2023)Geomagnetically Induced Currents (GICs), which are generated due to Geomagnetic Disturbances (GMDs), can saturate the cores of power transformers and their associated Current Transformers (CTs). To avoid maloperation of ... -
Stigma resistance versus self-stigma in university students with mental health problems
(2023)Self-stigma is the process by which an individual is aware of, agrees with, and internalizes demeaning societal stereotypes and prejudices. Stigma resistance is when an individual may be aware of societal stigma, yet ... -
Measurement of bimanual coordination in rehabilitation for poststroke individuals: a systematic review
(2023)A stroke can result in a decreased ability to coordinate the upper limbs, which leads to difficulty in performing the activities of daily living (ADLs). As a result, upper-extremity rehabilitation has been frequently ... -
Bioconversion of agricultural residues into value-added products by pectinase-producing bacteria and expression of pectinase gene in E. coli for biomass valorization
(2023)Pectinase is a group of enzymes that degrade pectin and is one of the most influential industrial enzymes, which helps produce varieties of good-quality products. These enzymes are ecofriendly, highly specific, sustainable, ... -
Late Holocene paleovegetation and fire history of Northern Lake of the Woods and the Woodland Period
(2023)This thesis analyzes two Late Holocene lake sediment cores which were collected from the vicinity of two archaeological sites in northeastern Lake of the Woods, Ontario: the Bundoran Site (DjKn-5) and the Bud Site (DjKn-6). ... -
Valorization of Kraft lignin via alkaline and acid- mediated aerobic oxidation processes
(2023)Lignin is a complex heterogeneous aromatic compound derived from renewable plant biomass. Due to its aromatic backbone, it has grown interested in producing biochemicals and other polymeric applications. Depending on the ... -
The phase behaviour of isopropanol/water/NaCl mixtures at atmospheric pressure
(2023)Alcohol-based biofuels will play a key role in substituting the fossil fuels used in transportation and power generation. Compared to fossil fuels, alcohol-based biofuels have a lower carbon footprint and can be produced ... -
Investigation of capacitor voltage balancing issues in a five-level inverter with multicarrier modulation schemes
(2023)Five-level inverters are widely used in medium-voltage (MV) wind energy and electric drive systems. However, the use of a large number of components (including passive and active components) and complex control methods ... -
Medical text simplification: bridging the gap between medical research and public understanding
(2023)Text Simplification is a subdomain of Natural Language Processing that focuses on applying computational techniques to modify the content and structure of the text to make it interpretable while retaining the main idea. ... -
An exploration of image recognition in archaeological starch analysis
(2023)The goal of this thesis was to produce a statistical method of assigning species to starch granules recovered from eastern North American archaeological assemblages. Starch grain analysis is an archaeobotanical tool that ... -
Geochemistry and mineralization of the Archean Titan (Roaring River) intrusion, Thunder Bay, Ontario
(2023)The 2690 ± 3.2 Ma Titan intrusion is an approximately 7 by 3 km, roughly ovoid, mafic-ultramafic intrusion, located just north of the inferred boundary between the Winnipeg River and Marmion terranes. Outcrop in the area ... -
Advanced deep regression models for smart operation of the oil and gas industry
(2023)The first industrial revolution in the early 18th century largely exploited steam power to replace animal labor. Since then, there has been rapid development in industrial operations. Now, the world has come to the brink ... -
Examining how early attachment contributes to later romantic relationship quality: the role of emotion regulation and conflict management strategies
(2023)Individuals with insecure styles of attachment often have difficulties with emotion regulation and conflict management and may utilize strategies to manage their emotions or navigate conflict that are maladaptive and ... -
Female care partners’ experiences of their relative's transition to nursing home: a critical feminist perspective
(2023)The decision to transition a relative to a nursing home is usually preceded by many months or years of physical and emotional care. While women continue to do most of the care work throughout their lives due to socially ... -
2D geometric morphometrics of murine mandibular toothrows from Liang Bua (Flores, Indonesia): implications for taxonomic identification
(2022)This study uses—and evaluates the efficacy of—two-dimensional geometric morphometrics (2DGM) to quantitatively characterize the size and shape of murine rodent (i.e., rat) mandibular molar rows from the archaeological ... -
New insights into modern human behaviour at Liang Bua (Flores, Indonesia) based on the temporal distribution of pottery and mollusks during the past 5,000 Years
(2022)In addition to preserving a rich archaeological record spanning from ~190 thousand years ago (ka) until the terminal Pleistocene, Liang Bua (Flores, Indonesia) also preserves a rich and relatively complete Holocene ... -
Nonlinear mathematical and numerical modeling of the effect of temperature on membrane pore size
(2022)Due to the growth of the global population, water stress has risen sharply. However, water stress in high latitudes is not only due to population growth but also to low local temperatures. Numerous studies have shown ... -
The influence of temperature on dynamic membrane structure
(2022)This study investigates the influences of cold source-water temperatures and warm temperature recoveries on the dynamic changes of membrane structure. The morphology of membrane pores on the membrane surface was firstly ... -
A numerical simulation study on the interaction of particles with rough surface and soft structures in suspension systems
(2022)Particle interactions in complex colloidal systems are essential in a variety of traditional and emerging industrial processes. This thesis applied the extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory to calculate ...
