Insect pest and disease incidence in Northwestern Ontario canola fields
(2022)While canola has enjoyed a long and lucrative history as a globally successful crop, it has only recently gained popularity in the Thunder Bay District, having been grown locally for just over 10 years. As part of any ... -
An Integrated Full-bridge Class-DE Ultrasound Transducer Driver for HIFU Applications
(2016)This thesis present a CMOS integrated transducer driver for high intensity focused ultrasound (HIFU) applications. Because this driver will be used in a magnetic resonance imaging (MRI) environment, no magnetic components ... -
Integrated solar electrokinetic remediation of soil contaminated with copper
(2012-11-10)Electrokinetic remediation is an emerging in-situ technology for cleaning contaminated soil. The contaminants are mobilized by passing a low-level direct current between a row of positively charged electrodes (anode) and ... -
An integrated ultrasound transducer driver for HIFU applications
(2014-01-22)This thesis proposes an MRI-compatible integrated CMOS ampli er that is capable of di- rectly driving an ultrasound transducer for HIFU applications. The output stage of the integrated amplifier operates in class DE mode ... -
Integrating a tactical harvest-scheduling model with a log sort-yard location model
(2014-01-22)Failure to sort logs prior to their transportation to a mill can result in a loss of value in the forest products supply chain—for unsorted, higher value logs can be used in a low-value product where lower valued logs ... -
Intelligent and cost-effective protection schemes for improved reliability of large-scale wind farms
(2021)Recently, wind power has become a reliable and cost-effective renewable energy source of electricity due to the foreseeable exhaustion of fossil fuel-based power generations and its growing adverse effects on the environment ... -
An intelligent monitoring system for online induction motor fault diagnostics
(2019)For more than a century, the induction motor (IM) has been the powerhouse industrial applications such as machine tools, manufacturing facilities, pumping stations, and more recently, in electric vehicles. In addition, ... -
Intelligent sliding mode control in flexible structures
(2012-11-10)The first objective of this work is to develop an intelligent sliding mode controller for vibration control in flexible structures. The proposed control consists of two processes: system identification and sliding mode ... -
An intelligent system for fault diagnosis in gearboxes
(2022)Gearboxes are commonly used in rotating machinery for power transmission. A gearbox consists of shafts, gears, and bearings, each component having specific mechanical dynamics and fault properties. Reliable gearbox fault ... -
An intelligent system for temperature monitoring and brake drum cooling
(2018)Brakes convert the kinetic energy of the moving vehicle into heat energy due to friction between fixed and moving brake parts. Frequent applications of the brakes will cause overheating in brake parts, which could generate ... -
Intelligent vehicle-to-vehicle communications with importance of fairness and information freshness
(2023)Intelligent Transportation Systems (ITS) showcase cutting-edge services designed to revolutionize transportation and mobility, especially within future smart cities. These services play a pivotal role in bolstering traffic ... -
Interaction of lignin derivatives with polymers, ions and soft surfaces in aqueous systems
(2021)Lignin is one of the most abundant biopolymers on earth which has recently gained considerable attention due to its unique potentials to be used in many applications. Many efforts have been made in improving the compatibility ... -
Interactive effects of elevated CO2 and temperature, nutrition, and ectomycorrhizas on morphological traits and summer shoot formation in jack pine
(2022)Understanding the responses of trees, ectomycorrhizal fungi (ECM) and their association to climate change can be challenging due to their interactions with multiple environmental factors. The combined impacts of elevated ... -
Interactive effects of soil temperature and resource availability on physiological and growth responses of white birch (Betula papyrifera) seedlings to atmospheric carbon dioxide elevation
(2009)Predicting the impacts of future high atmospheric CO2 concentration, [CO2], on the physiology and growth of boreal forests is complicated by interactions of CO2 with other environmental conditions. Two-factor CO2 x environment ... -
Intermediate students at-risk in mathematics : case studies of teachers and students
(2009)Although there have been changes made to Ontario's mathematics curriculum within the last decade to ensure student success, a significant number of students in Ontario schools have been achieving at or below a level 1 and ... -
Interpersonal experiences of the clinically depressed: excessive reassurance seeking and negative feedback seeking
(2013)Individuals with depression can engage in aversive interpersonal behaviours, such as excessive reassurance seeking and negative feedback seeking, which can themselves be associated with problematic social relationships. ... -
Interpreting the spatial distribution of lithic artifacts from the RLF Paleoindian site (DdJf-13), Thunder Bay Region, Northwestern Ontario
(2015-06-15)This thesis explores the intra-site organization of Late Paleoindian, Lakehead Complex populations at the RLF site (DdJf-13), located east of Thunder Bay, Ontario. Situated upon a relic Lake Minong beach ridge, the RLF ... -
Interprofessional care in a community mental health outpatient program: client outcomes at discharge and follow-up
(2013-02-03)Increased collaboration between health professionals has been identified as a means of improving the quality of client care while operating within the constraints of a publicly funded health care system. One such model of ... -
Interspecific interactions modulate social foraging behaviour and habitat use in a neotropical migratory warbler species during its nonbreeding period
(2022)Spatial and temporal variation in biotic and abiotic conditions in any foraging environment prompts individuals to modify their strategies of space use and behavioral responses such as going from solitary to social ... -
Intra-lake and inter-lake variation in copper tolerance in Daphnia from clean and metal-contaminated lakes
(2014-01-22)The freshwater invertebrate Daphnia can persist in historically metal-contaminated lakes due to its ability to adapt to metal contamination. Since different Daphnia isolates have been shown to have varying degrees of ...
