An investigation of low energy quasiparticle excitations via thermal transport measurements
(University of Waterloo, 2017-06-16)Thermal transport measurements can provide a unique perspective of the nature of a system by exploring the behaviour of the low energy excitations from the ground state. Delocalized quasiparticle excitations can affect ... -
An Investigation of Manganese Macro segregation in Cast Dual Phase Steels using Micro X-ray Fluorescence Spectroscopy
(University of Waterloo, 2017-10-18)Advanced High Strength Steels with a high manganese content offer an exceptional balance of strength and ductility. However, the occurrence of segregation in these steels, particularly at the centerline, leads to quality ... -
An Investigation of Methods for Missing Data in Hierarchical Models for Discrete Data
(University of Waterloo, 2011-03-09)Hierarchical models are applicable to modeling data from complex surveys or longitudinal data when a clustered or multistage sample design is employed. The focus of this thesis is to investigate inference for discrete ... -
An Investigation of Methods to Attenuate Soft Tissue Artifact of the Thigh in High Knee Flexion
(University of Waterloo, 2020-08-26)Soft tissue artifact during optical motion capture, or the movement of skin markers relative to bone, is widely accepted as a significant source of error in estimations of angles and moments. In some cases, the error ... -
Investigation of Microbial Electrochemical Cell (MEC) as a Sustainable Alternative for Synthesizing Hydrogen Peroxide (H2O2)
(University of Waterloo, 2015-01-28)Hydrogen peroxide (H2O2) is an environmentally-safe strong oxidant that has many practical applications. While H2O2 is capable of oxidizing a variety of contaminants, its end products are only H2O and O2. As a result, ... -
Investigation of Microbial Fuel Cell Performance and Microbial Community Dynamics During Acclimation and Carbon Source Pulse Tests
(University of Waterloo, 2007-10-24)Microbial fuel cells were designed and operated using waste activated sludge as a substrate and as a source of microorganisms for the anodic chamber. Waste activated sludge provided a bacterial consortium predisposed to ... -
Investigation of Milk and Alternatives Intake and the Impact of School Nutrition Programs in First Nations Schoolchildren
(University of Waterloo, 2010-08-31)Objectives: To assess the intake of milk and alternatives, calcium, and vitamin D in on-reserve First Nations youth in Ontario, Canada; and the relationship of these nutrients to body mass index. To assess the impact of ... -
Investigation of Mixing Models and Finite Volume Conditional Moment Closure Applied to Autoignition of Hydrogen Jets
(University of Waterloo, 2012-03-09)In the present work, the processes of steady combustion and autoignition of hydrogen are investigated using the Conditional Moment Closure (CMC) model with a Reynolds Averaged Navier-Stokes (RANS) Computational Fluid ... -
Investigation of MoO3 as an electron injection contact and as a charge transport material in transparent organic light emitting devices
(University of Waterloo, 2011-08-24)MoO3 is investigated for its utilization as a transparent cathode and as a charge transport material in transparent organic light emitting devices. As a transparent cathode, MoO3 is utilized in combination with a thin metal ... -
Investigation of multi-criteria decision analysis approaches for agricultural decision-making in southern Ontario
(University of Waterloo, 2016-08-26)Land-use and land-cover change has significant impact on the Earth’s ecosystems and global carbon cycle, which calls for well-planned land management strategies. This study presented a multi-criteria decision analysis ... -
Investigation of Multiple Well Injections for Carbon Dioxide Sequestration in Aquifers
(University of Waterloo, 2014-09-02)As the amount of CO2 present in the atmospheres is increasing due to combustion emission, it is becoming more and more important to find ways to reduce greenhouse gas emissions. One of the ways to do that is through carbon ... -
An Investigation of Nitrification Predictors and Factors in Two Full-Scale Drinking Water Distribution Systems
(University of Waterloo, 2012-01-10)The biologically-mediated process of nitrification can occur in chloraminated drinking water distribution systems. In this process, ammonia is oxidized to nitrite by ammonia-oxidizing bacteria (AOB) and archaea (AOA). In ... -
An Investigation of Non-stationary Nature of Environmental Data
(University of Waterloo, 2019-04-17)Several investigations have shown that the Earth's climate is experiencing change, as evident by rising global temperatures, receding ice sheets and reducing glacier sizes. There is also empirical observation supporting ... -
