The influence of social media and contract cheating website use on the perception of academic integrity standards
(2023)This work sought to address gaps in the literature regarding perceived student acceptance of certain types of cheating in higher education and the potential relationships to social media use and the digital academic ... -
The influence of stimulants on truck driver culpability in fatal collisions
(2011)Given the monotony and extended driving periods inherent in transport truck driving, truck drivers might rely on stimulants to sustain attention and combat fatigue. Research indicates stimulants improve some cognitive ... -
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 ... -
The influence of water table fluctuation on hydrarch succession in two subarctic peatlands in Eastern James Bay, Quebec
(2019)Northern peatlands contain close to one-third of the world’s soil carbon and changes to their ecology and hydrology play a major role in the fate of these carbon stocks and the direction of their climate feedbacks. Recent ... -
The Influence of wetlands and watershed geology on lake chemistry of five remote lakes in Northwestern Ontario
(2012-11-10)In chapter 1 of this study the relationship between spatial, chemical, and biological factors and their influence on mercury concentration s in walleye were examined. Water, sediment, and fish tissue samples were collected ... -
Informal STEM Education for Underrepresented Racial Minorities: Students’ Perceptions of the Imhotep’s Legacy Academy After-school Programme
(2016-01-05)This study explores students' perceptions of the Imhotep's Legacy Academy After-School Project (ILASP), an after-school STEM programme offered to Nova Scotian students of African descent. A sequential explanatory mixed-methods ... -
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
