Integrating Structure and Meaning: Using Holographic Reduced Representations to Improve Automatic Text Classification
(University of Waterloo, 2008-07-10)Current representation schemes for automatic text classification treat documents as syntactically unstructured collections of words (Bag-of-Words) or `concepts' (Bag-of-Concepts). Past attempts to encode syntactic structure ... -
Vehicle Tracking in Outdoor Environments using 3D Models
(University of Waterloo, 2008-07-23)There has been a growth in demand for advancing algorithms in surveillance applications concerning moving vehicles where analysis of traffic has a potential application to security, traffic management (congestion and ... -
Wavelet Shrinkage Based Image Denoising using Soft Computing
(University of Waterloo, 2008-08-22)Noise reduction is an open problem and has received considerable attention in the literature for several decades. Over the last two decades, wavelet based methods have been applied to the problem of noise reduction and ... -
Audification of Ultrasound for Human Echolocation
(University of Waterloo, 2008-08-22)Individuals with functional blindness must often utilise assistive aids to enable them to complete tasks of daily living. One of these tasks, locomotion, poses considerable risk. The long white cane is often used to ... -
Carbon Nanotube and Carbon Fibre Based Radiation Dosimetry
(University of Waterloo, 2008-08-25)The principle of radiobiology and, hence, clinical outcomes in radiotherapy are inherently dependent on accurate radiation dosimetry. Over the last few decades, ionization chambers, thermoluminescence dosimeters (TLDs), ... -
3D MEMS Microassembly
(University of Waterloo, 2008-09-03)Due to the potential uses and advantages of 3D microelectromechanical systems (MEMS), research has been ongoing to advance the field. The intention of my reasearch is to explore different gripper designs and their ... -
Design of Carbon Nanotube Based Field Emission Facility
(University of Waterloo, 2008-09-12)The objective of this research is to build a prototype of a carbon nanotube (CNT)-based micro X-ray tube array, which can be used in a real-time cone-beam computed tomography (CT) scanner for cancer research. The X-ray ... -
Multiple Cooperative Swarms for Data Clustering
(University of Waterloo, 2008-09-24)Exploring a set of unlabeled data to extract the similar clusters, known as data clustering, is an appealing problem in machine learning. In other words, data clustering organizes the underlying data into different ... -
Improved image speckle noise reduction and novel dispersion cancellation in Optical Coherence Tomography
(University of Waterloo, 2008-09-25)Optical coherence tomography (OCT) is an innovative modern biomedical imaging technology that allows in-vivo, non-invasive imaging of biological tissues. At present, some of the major challenges in OCT include the need for ... -
Oppositional Reinforcement Learning with Applications
(University of Waterloo, 2008-09-25)Machine intelligence techniques contribute to solving real-world problems. Reinforcement learning (RL) is one of the machine intelligence techniques with several characteristics that make it suitable for the applications, ... -
The transformation of one-dimensional and two-dimensional autoregressive random fields under coordinate scaling and rotation
(University of Waterloo, 2008-11-05)A practical problem in computer graphics is that of representing a textured surface at arbitrary scales. I consider the underlying mathematical problem to be that of interpolating autoregressive random fields under arbitrary ... -
A Strain Energy Function for Large Deformations of Curved Beams
(University of Waterloo, 2008-12-05)This thesis develops strain and kinetic energy functions and a finite beam element useful for analyzing curved beams which go through large deflections, such as a hockey stick being swung and bent substantially as it hits ... -
Integrated Robust Design Using Response Surface Methodology and Constrained Optimization
(University of Waterloo, 2008-12-19)System design, parameter design, and tolerance design are the three stages of product or process development advocated by Genichi Taguchi. Parameter design, or robust parameter design (RPD), is the method to determine ... -
A Search For Principles of Basal Ganglia Function
(University of Waterloo, 2009-01-13)The basal ganglia are a group of subcortical nuclei that contain about 100 million neurons in humans. Different modes of basal ganglia dysfunction lead to Parkinson's disease and Huntington's disease, which have debilitating ... -
Modeling and Analysis of Multilateral Negotiations
(University of Waterloo, 2009-01-19)Abstract The modeling and analysis of multilateral negotiations are studied under the assumption that reaching an agreement is the main objective of the negotiators. A new methodology and associated definitions are ... -
