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 ...
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 ...
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). ...
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 ...
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 ...
Assessing the vulnerability of south-central Ontario’s maple syrup industry to climate change: a multidisciplinary approach
(2023)
Productivity of Ontario’s maple syrup industry is tied to a specific climate window. As
climate continues to change, there is growing concern over the industry’s vulnerability given its
reliance on stable climate conditions ...
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 ...
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 ...
Preliminary identification and therapeutic support of depression in mental health using conversational AI
(2023)
World Health Organization statistics indicate that one out of every eight people suffers from
mental illness. Due to the fear of stigma and social discrimination, they start being resilient and
end up going through ...
