A Hybrid Symbolic-Numeric Method for Multiple Integration Based on Tensor-Product Series Approximations
(University of Waterloo, 2004)This work presents a new hybrid symbolic-numeric method for fast and accurate evaluation of multiple integrals, effective both in high dimensions and with high accuracy. In two dimensions, the thesis presents an adaptive ... -
A Hybrid Theory of Evidence
(University of Waterloo, 2013-10-28)In the literature on doxastic evidence, the phenomenon is regarded as either internal (Plantinga 1993, Feldman and Conee 2001, Turri 2009) or external (Armstrong 1973, Collins 1997, BonJour 2008). Though the specifics of ... -
Hybrid Thresholds, Redefining the Don River’s Edge
(University of Waterloo, 2015-09-28)My proposal envisions the threshold between the built urban fabric and the natural environment at the water’s edge. It focuses on the development of public space at the water’s edge, and tries to transform that space ... -
Hybrid Time and Time-Frequency Blind Source Separation Towards Ambient System Identi cation of Structures
(University of Waterloo, 2010-08-24)Blind source separation methods such as independent component analysis (ICA) and second order blind identification (SOBI) have shown considerable potential in the area of ambient vibration system identification. The objective ... -
Hybrid Tin Based Nanostructures Wrapped with Graphene as Efficient Anode Material for Lithium Ion Batteries
(University of Waterloo, 2015-08-12)Recently, many developments in the electric & hybrid electric vehicles, and in the electronic devices, have resulted in an increasing demand for high power and high energy density lithium-ion batteries. The current commercial ... -
Hybrid Transparent Conductive Oxide Nanostructured Materials for Photovoltaic Applications
(University of Waterloo, 2015-10-09)In Ontario, there are great incentives to invest in solar cell research through the Feed-In Tariff program, which has successfully increased the total connected capacity of solar power in Ontario to well over 215 MW. ... -
HybridPointing Touch: A Technique to Switch Between Absolute and Relative Pointing on Large Touch Screens
(University of Waterloo, 2017-10-25)We extend Forlines et al.'s idea of mixed absolute and relative "HybridPointing" to large multitouch displays. In our bimanual "CursorTap" interaction technique, one hand triggers a kinaesthetic relative pointing mode while ... -
Hydraulic Performance of the Seepage Collection Ditches at the Albian Sands Muskeg River Mine
(University of Waterloo, 2006)The tailings pond at the Muskeg River Mine is a large structure with a 11 km-long ring dyke that contains process affected water (PAW) and tailings sand. The dyke is made of permeable tailings sand and therefore it is ... -
Hydraulic Road Binder (HRB) and Its Use for Subgrade Stabilization in Ontario, Canada
(University of Waterloo, 2019-12-18)The term “subgrade” refers to the in-situ material composed of natural soil located underneath the pavement structural layers. The quality of natural subgrade is highly influenced by soil type, moisture content, and organic ... -
Hydraulic Tomography Analyses of Different Datasets for Subsurface Heterogeneity Characterization at Various Scales
(University of Waterloo, 2023-08-21)Hydraulic Tomography (HT) has been evaluated to be a robust approach for high-resolution characterization of subsurface heterogeneity. However, geostatistics-based HT may produce overly smooth distributions of hydraulic ... -
Hydraulic Tomography and Trichloroethene Dissolution in a Fractured Dolostone: Small Scale Laboratory Experiments
(University of Waterloo, 2011-12-21)In fractured geologic media, flow and contaminant transport are predominantly controlled by the fractures, their distribution and connectivity. The accurate characterization of fractured geologic medium, imaging of fracture ... -
Hydraulic Tomography in Unconfined Aquifers and the Importance of Geological Data: Laboratory and Field Studies
(University of Waterloo, 2017-01-10)This dissertation first demonstrates the effectiveness of hydraulic tomography (HT) in characterizing the heterogeneity of both the saturated and unsaturated zone parameters through a laboratory unconfined aquifer. ... -
Hydraulic Tomography: Field and Laboratory Experiments
(University of Waterloo, 2011-05-17)Accurately characterizing the distribution of hydraulic parameters is critical for any site investigation, particularly those dealing with solute or contaminant transport. Despite the fact that many tools are currently ... -
Hydraulic Variable Valve Actuation on a Single Cylinder Engine
(University of Waterloo, 2017-12-19)The combustion characteristics in an engine cylinder can greatly change over a range of speeds and loads. However, conventional engines x the timing and amount of intake and exhaust, which can lead to higher emissions, ... -
Hydraulic Variable Valve Actuation System: Development & Validation
(University of Waterloo, 2019-08-27)Conventional engines with camshafts with fixed timings force a compromise between performance at high engine loads and fuel economy at low engine loads. Adjusting internal combustion engine valve timing and lift through a ... -
Hydraulic Variable Valve Timing Testing and Validation
(University of Waterloo, 2016-06-30)This thesis documents the development of a fully continuous, hydraulics-based variable valve timing system. This hydraulics based variable valve timing system is capable of controlling an engine valves lift height and ... -
Hydride Generation as a Sample Introduction Technique for Detection of Arsenic by Microplasma
(University of Waterloo, 2023-12-08)Microplasma can be used as a portable analytical instrument for elemental analysis of samples due to their small size, low power consumption, low carrier gas consumption, and low cost. This is specifically important for ... -
