Gaits and Their Development in the Infraorder Pecora
(University of Waterloo, 1967-02)The gaits of twenty-eight species of the Infraorder Pecora are analyzed from motion picture sequences comprising over 45,000 frames. For each gait the percentage time spent on the various supporting legs during each stride ... -
The electrostatic potential in a finite ionic crystal
(University of Waterloo, 1972-11-01)This thesis is written in two parts. In Part One, we develop a new method for evaluating three dimensional lattice summations and apply it to the evaluation of the electrostatic potential of a finite ionic crystal. We then ... -
The Tracing of a Contaminant (Tritium) from Candu Sources: Lake Ontario
(University of Waterloo, 1997)In any research program we begin with a hypothesis and when our expected results do not concur with the observed results we must try and understand the dynamics behind the changed process. In this study we were trying ... -
Effect of Fuel Ethanol on Subsurface Microorganisms and its Influence on Biodegradation of BTEX Compounds.
(University of Waterloo, 2000)Ethanol is used as fuel in neat form in some countries (Brazil and India) or blended with gasoline (Europe, Canada and the United States). The benefits of ethanol use include octane enhancement, a cleaner environment and ... -
Numerical Simulation of Hydrocarbon Fuel Dissolution and Biodegradation in Groundwater
(University of Waterloo, 2000)The behaviour of hydrocarbon fuels in contaminated groundwater systems is studied using a multicomponent reactive transport model. The simulated processes include residual NAPL dissolution, aerobic and anaerobic ... -
A Quasilocal Hamiltonian for Gravity with Classical and Quantum Applications
(University of Waterloo, 2000)I modify the quasilocal energy formalism of Brown and York into a purely Hamiltonian form. As part of the reformulation, I remove their restriction that the time evolution of the boundary of the spacetime be orthogonal ... -
Direct Fitting of Analytical Potential Functions to Diatomic Molecular Spectroscopic Data
(University of Waterloo, 2000)The standard practice of spectroscopic data reduction is generally to fit data to level energy expansions in terms of the vibrational and rotational quantum numbers. However, the utility of such expressions is limited ... -
Physical Hydrogeology and Impact of Urbanization at the Waterloo West Side: A Groundwater Modelling Approach
(University of Waterloo, 2000)In the last few decades protection of the environment has moved to the forefront of earth science research. Sustainable development is becoming more important to rapidly growing communities throughout southern Ontario ... -
Supercooling and Freezing of HNO3/H2O Aerosols
(University of Waterloo, 2000)The freezing kinetics of binary nitric acid/water aerosols is of fundamental importance to the modelling of polar stratospheric clouds and the role they in ozone depletion over the Arctic/Antarctic regions. Cirrus clouds ... -
Methodologies for capture zone delineation for the Waterloo Moraine well fields
(University of Waterloo, 2000)The Region of Waterloo relies mainly (75 %) on local groundwater resources for its drinking water supply. The water demand is increasing with the growth of the population and there is a need to enhance the present water ... -
Pulse Flow Enhancement in Two-Phase Media
(University of Waterloo, 2001)This laboratory project has been done to evaluate pressure pulsing as an Enhanced Oil Recovery (EOR) technique. To perform the study, a consistent laboratory methodology was developed, including the construction of a ... -
Noble Gas Collision Induced Vibrational Relaxation of (v=1) para-H2
(University of Waterloo, 2001)Close coupling scattering calculations have been conducted for the para spin modification of H<sub>2</sub>-{He, Ne and Ar}. The XC(fit) potential energy surfaces for H<sub>2</sub>-Ne and H<sub>2</sub>-Ar have been used ... -
Determining Analytical Potential Energy Functions of Diatomic Molecules by Direct Fitting
(University of Waterloo, 2001)The fully quantum mechanical 'direct-potential-fit' (DPF) method has become increasingly widely used in the reduction of diatomic spectra. The central problem of this method is the representation of the potential energy ... -
Modelling Quantum Well Lasers
(University of Waterloo, 2002)In this thesis, two methods to model quantum well lasers will be examined. The first model is based on well-known techniques to determine some of the spectral and dynamical properties of the laser. For the spectral ... -
Sources and Controls of Sulphur Export in Precambrian Shield Catchments in South-central Ontario
(University of Waterloo, 2002)A series of studies was undertaken at Plastic Lake-1 (PC1) to determine the sources and controls on S cycling in small headwater catchments on the Precambrian Shield in south-central Ontario. Two observations were made ... -
A process-based stable isotope approach to carbon cycling in recently flooded upland boreal forest reservoirs
(University of Waterloo, 2002)Reservoirs impound and store large volumes of water and flood land. The water is used for electricity generation, irrigation, industrial and municipal consumption, flood control and to improve navigation. The ... -
Numerical Simulation of Road Salt Impact at the Greenbrook Well Field, Kitchener, Ontario
(University of Waterloo, 2002)Chloride concentrations at the Greenbrook well field in Kitchener, Ontario, have been steadily increasing over the past several decades and may soon pose a threat to drinking water quality. Drinking water limits at some ... -
HIGH RESOLUTION MICROWAVE SPECTROSCOPY OF ULTRA COLD RYDBERG ATOMS AS A PROBE OF ELECTRIC AND MAGNETIC FIELDS
(University of Waterloo, 2003)In highly excited Rydberg atoms, the excited electron is in a large, loosely bound orbit. Hence, in contrast with the ground states, the Rydberg states are very sensitive to external electric field and can be ionized in ... -
Characterisation and Optimization of Ultrashort Laser Pulses
(University of Waterloo, 2003)The ultrafast optical regime is defined, as it applies to laser pulses, along with a brief introduction to pulse generation and characterisation technologies. A more extensive description of our particular amplified ... -
Intermediate and Low Level Nuclear Waste Stabilisation: Carbonation of Cement-based Wasteforms
(University of Waterloo, 2003)Carbonation is a naturally-occurring process whereby Ca-containing cement phases lose their hydration water and are converted to carbonate minerals by reaction with atmospheric CO₂. As these secondary minerals ...
