Adapting Evolutionary Approaches for Optimization in Dynamic Environments
(University of Waterloo, 2006)Many important applications in the real world that can be modelled as combinatorial optimization problems are actually dynamic in nature. However, research on dynamic optimization focuses on continuous optimization ... -
Application of Data mining in Medical Applications
(University of Waterloo, 2004)Abstract Data mining is a relatively new field of research whose major objective is to acquire knowledge from large amounts of data. In medical and health care areas, due to regulations and due to the availability ... -
Automated Selection of Modelling Coordinates for Forward Dynamic Analysis of Multibody Systems
(University of Waterloo, 2006)Modelling mechanical systems using symbolic equations can provide many advantages over the more widely-used numerical methods of modelling these systems. The use of symbolic equations produces more efficient models, which ... -
Automatically Measuring Neuromuscular Jitter
(University of Waterloo, 2005)The analysis of electromyographic (EMG) signals detected during muscle contraction provides important information to aid in the diagnosis and characterization of neuromuscular disorders. One important analysis measures ... -
Average Cell Orientation, Eccentricity and Size Estimated from Tissue Images
(University of Waterloo, 2005)Five image processing algorithms are proposed to measure the average orientation, eccentricity and size of cells in images of biological tissue. These properties, which can be embodied by an elliptical 'composite cell', ... -
Cleanup Memory in Biologically Plausible Neural Networks
(University of Waterloo, 2005)During the past decade, a new class of knowledge representation has emerged known as structured distributed representation (SDR). A number of schemes for encoding and manipulating such representations have been developed; ... -
Color Image Edge Detection and Segmentation: A Comparison of the Vector Angle and the Euclidean Distance Color Similarity Measures
(University of Waterloo, 1999)This work is based on Shafer's Dichromatic Reflection Model as applied to color image formation. The color spaces RGB, XYZ, CIELAB, CIELUV, rgb, l1l2l3, and the new h1h2h3 color space are discussed from this perspective. ... -
Cooperative Water Resources Allocation among Competing Users
(University of Waterloo, 2005)A comprehensive model named the Cooperative Water Allocation Model (CWAM) is developed for modeling equitable and efficient water allocation among competing users at the basin scale, based on a multiperiod node-link river ... -
Determinants of Increased Energy Cost in Prosthetic Gait
(University of Waterloo, 2004)The physiological energy requirements of prosthetic gait in lower-limb amputees have been observed to be significantly greater than those for able-bodied subjects. However, existing models of energy flow in walking have ... -
The Development of System Identification Approaches for Complex Haptic Devices and Modelling Virtual Effects Using Fuzzy Logic
(University of Waterloo, 2005)Haptic applications often employ devices with many degrees of freedom in order to allow the user to have natural movement during human-machine interaction. From the development point of view, the complexity in ... -
Dynamic Model of a Piano Action Mechanism
(University of Waterloo, 2004)While some attempts have been made to model the behaviour of the grand piano action (the mechanism that translates a key press into a hammer striking a string), most researchers have reduced the system to a simple model ... -
E-Intelligence Form Design and Data Preprocessing in Health Care
(University of Waterloo, 2004)Clinical data systems continue to grow as a result of the proliferation of features that are collected and stored. Demands for accurate and well-organized clinical data have intensified due to the increased focus on ... -
Effects of Decision Support Tools on Cardiac Telephone Consultation Process
(University of Waterloo, 2006)The Nursing Coordinators (NCs) at the University of Ottawa Heart Institute (UOHI) fields phone calls from patients who have been discharged and are undergoing home care procedures at a daily basis. The project described ... -
Emotion, Perception and Strategy in Conflict Analysis and Resolution
(University of Waterloo, 2006)Theoretical procedures are developed to account for the effect of emotion and perception in strategic conflict. The <em>possibility principle</em> facilitates modeling the effects of emotions on future scenarios contemplated ... -
Evolutionary Design for Computational Visual Attention
(University of Waterloo, 2003)A new framework for simulating the visual attention system in primates is introduced. The proposed architecture is an abstraction of existing approaches influenced by the work of Koch and Ullman, and Tompa. Each stage ... -
Examining the Process of Automation Development and Deployment
(University of Waterloo, 2005)In order to develop a better understanding of the process of development and deployment of automated systems, this thesis examines aspects of project execution and knowledge transfer in the context of a large automation ... -
Feasibility Analysis of a Powered Lower-Limb Orthotic for the Mobility Impaired User
(University of Waterloo, 2005)Powered orthotic devices can be used to restore mobility to the impaired user, and may thereby assist them in daily living tasks. An investigation is performed herein to examine the feasibility of a powered lower-limb ... -
Image Models for Wavelet Domain Statistics
(University of Waterloo, 2005)Statistical models for the joint statistics of image pixels are of central importance in many image processing applications. However the high dimensionality stemming from large problem size and the long-range spatial ... -
Implementation of a Variable Duty Factor Controller on a Six-Legged Axi-Symmetric Walking Robot
(University of Waterloo, 2006)Hexplorer is a six-legged walking robot developed at the University of Waterloo. The robot is controlled by a network of seven digital signal processors, six of which control three motors each, for a total of 18 motors. ... -
