The participatory design of an ecosystem approach to monitoring in support of sense-making: What's the Point?
(University of Waterloo, 1999)Environmental monitoring initiatives are typically conceived as strictly scientific affairs designed to provide support for managerial decision-making; as a consequence most initiatives are centered on a formal mandate or ... -
Convex Optimization and Utility Theory: New Trends in VLSI Circuit Layout
(University of Waterloo, 1999)The design of modern integrated circuits is overwhelmingly complicated due to the enormous number of cells in a typical modern circuit. To deal with this difficulty, the design procedure is broken down into a set of ... -
Some Problems in One-Operator Scheduling
(University of Waterloo, 1999)A flexible workforce or a versatile machine is employed to perform various types of operations. Often these resources are associated with setups. Whenever a worker or machine switches from processing one type of operation ... -
Multi-Resolution Approximate Inverses
(University of Waterloo, 1999)This thesis presents a new preconditioner for elliptic PDE problems on unstructured meshes. Using ideas from second generation wavelets, a multi-resolution basis is constructed to effectively compress the inverse of the ... -
Motivated Resistance to Counterattitudinal Arguments: The effects of affirmation, argument strength and attitude importance
(University of Waterloo, 2000)In this study we explored some of the factors associated with biased processing of attitude-relevant information. We were particularly interested in the possibility that a self-affirmation, by reducing self-evaluative ... -
The Model Theory of Algebraically Closed Fields
(University of Waterloo, 2000)Model theory can express properties of algebraic subsets of complex n-space. The constructible subsets are precisely the first order definable subsets, and varieties correspond to maximal consistent collections of ... -
Contributions to the Study of the Validity of Huygens' Principle for the Non-self-adjoint Scalar Wave Equation on Petrov Type D Spacetimes
(University of Waterloo, 2000)This thesis makes contributions to the solution of Hadamard's problem through an examination of the question of the validity of Huygens'principle for the non-self-adjoint scalar wave equation on a Petrov type D spacetime. ... -
An Approximation Algorithm for Character Compatibility and Fast Quartet-based Phylogenetic Tree Comparison
(University of Waterloo, 2000)Phylogenetic analysis, or the inference of evolutionary history is done routinely by biologists and is one of the most important problems in systematic biology. In this thesis, we study two computational problems in ... -
Matrix Formulations of Matching Problems
(University of Waterloo, 2000)Finding the maximum size of a matching in an undirected graph and finding the maximum size of branching in a directed graph can be formulated as matrix rank problems. The Tutte matrix, introduced by Tutte as a representation ... -
On the Solution of the Hamilton-Jacobi Equation by the Method of Separation of Variables
(University of Waterloo, 2000)The method of separation of variables facilitates the integration of the Hamilton-Jacobi equation by reducing its solution to a series of quadratures in the separable coordinates. The case in which the metric tensor is ... -
A Predictive Control Method for Human Upper-Limb Motion: Graph-Theoretic Modelling, Dynamic Optimization, and Experimental Investigations
(University of Waterloo, 2000)Optimal control methods are applied to mechanical models in order to predict the control strategies in human arm movements. Optimality criteria are used to determine unique controls for a biomechanical model of the human ... -
Acceptance of a Remote Desktop Access System to Increase Workspace Awareness
(University of Waterloo, 2000)Awareness systems are being designed and implemented to improve employee connections. This study examines the variables that affect the acceptance of an awareness system. The awareness system that was used for this ... -
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 ... -
Fundamental Characteristics of Turbulent Opposed Impinging Jets
(University of Waterloo, 2000)A fundamental study of two turbulent directly opposed impinging jets in a stagnant ambient fluid, unconfined or uninfluenced by walls is presented. By experimental investigation and numerical modeling, the main characteristics ... -
Efficient Analysis for Nonlinear Effects and Power Handling Capability in High Power HTSC Thin Film Microwave Circuits
(University of Waterloo, 2000)In this study two nonlinear analysis methods are proposed for investigation of nonlinear effects of high temperature superconductive(HTSC) thin film planar microwave circuits. The MoM-HB combination method is based on ... -
Inorganic Phosphor Coatings for Ultraviolet Responsive Image Detectors
(University of Waterloo, 2000)Typical CCD digital imaging sensors are insensitive to ultraviolet ( UV ) radiation by virtue of the very shallow ( 2 nm ) penetration depth in silicon. This warrants the use of a post-packaging coating to up-covert the ... -
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 ... -
A Study of the Automatic Speech Recognition Process and Speaker Adaptation
(University of Waterloo, 2000)This thesis considers the entire automated speech recognition process and presents a standardised approach to LVCSR experimentation with HMMs. It also discusses various approaches to speaker adaptation such as MLLR and ...
