Using vehicular traffic count data to estimate the factors driving water-based recreation use in northwestern Ontario, Canada
(2010)Within Canada's publicly owned forests (i.e., Crown forests), little information is available about how and when people use lakes and rivers for recreation. I report an example of using traffic monitoring to identify both ... -
Utility of the theory of planned behaviour in health services research when examining the intentions of immunization provider behaviour
(2009)This paper will demonstrate the need for public health involvement with health services research in order to effectively meet its' mandate for achieving population health. The success of our public health programs requires ... -
Utilization of alternative testing methods in the evaluation of pulp and paper mill effluent toxicity
(2020)Pulp mills are required to perform routine regulatory testing to ensure the effluent they release from their water treatment plants is not harmful to humans and the environment. The key components within the effluent ... -
Utilization of coal biomass fly ash in the control and treatment of acid mine drainage
(2009)This study investigated the feasibility of using coal/biomass fly ash (CBFA) blended with various percentages of mine tailings, bentonite, and glacial till soil to control and treat acid mine drainage (AMD). Applications ... -
Utilization of hydrodynamic modeling in predicting water quality and Brook Trout habitat: reclamation of a mine impacted Boreal Shield Lake
(2020)Mining operations in Ontario are subject to regulatory limits on effluent release into surrounding waterbodies designed to preserve aquatic life. However, said guidelines may not always be enough to prevent damage to the ... -
Utilization of wood based hemicellulose pre-hydrolysate for the production of high value added platform chemicals
(2017)The immense benefits of using renewable resources are because they can reduce global warming and other environmental issues which directly affect life on earth. Forest residues serve as potential renewable resources which ... -
UWB localization for autonomous indoor position control of VTOL UAVs
(2018)As the popularity of quadrotor Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicles (UAVs) grows, the need for reliable position estimation and control grows as well. Furthermore, with the size of these quadrotors ... -
Validation of discrete ordinate radiation model for application in UV air disinfection modeling
(2014)This study investigated one of the most important aspect of ultra-violet (UV) air disinfection modeling which is radiation modeling. Radiation modeling is a topic of interest in the domain of UV air disinfection research. ... -
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 ... -
Vapnik-Chervonenkis dimension in neural networks
(2023)This thesis aims to explore the potential of statistical concepts, specifically the Vapnik-Chervonenkis Dimension (VCD)[33], in optimizing neural networks. With the increasing use of neural networks in replacing human ... -
Variability in women's perception of potential female rivals: effects of fertility, mating orientation, and revealing dress biases
(2017)Two studies were conducted to better understand individual difference factors that influence women’s mating-relevant perceptions of other women. In Study 1, biases about revealing dress were examined and the extent to which ... -
Variation in vessel diameter and leaf area of white birch (Betula papyrifera) along moisture gradients in Canada
(2010)One of the key hypotheses of this research is that white birch that has evolved in wet areas will have larger vessels than those trees that evolved in dry areas. Since the wet areas are less likely to experience drought ... -
Vibration control using switchable stiffness
(2015-01-13)Over the last decade, the switchable stiffness (SS) control strategy has seen renewed academic interest due to the need for effective vibration control techniques. The SS control strategy involves switching the system’s ... -
Vibration suppression and energy harvesting with a variant nonlinear energy sink
(2018)Vibration control is aimed to suppress or eliminate unwanted vibration to ensure proper operation of machines. On the other hand, energy harvesting intends to scavenge energy from ambient vibrations to power electronical ... -
Violence and masculinity in Hollywood war films during World War II
(2013-02-03)During World War II, the Hollywood studios produced an unprecedented number of war-themed films in order to help prepare American audiences for what was to come, as well as to profit from the popularity of anything pertaining ... -
Virtual work from home and mental health: a mixed methods systematic review
(2021)Poor mental health is a risk factor for a number of chronic physical conditions and may impact individuals’ ability to remain in the work force (World Health Organization, 2004b). Further, the workplace itself may pose ... -
Visible light positioning systems under imperfect synchronization and signal-dependant noise
(2022)Optical Wireless Communication (OWC) is an enabling technology for sixth-generation (6G) and beyond communication networks. Visible light communication (VLC) is a crucial branch of OWC technology expected to meet 6G ... -
