Wavelet Filter Banks in Perceptual Audio Coding
(University of Waterloo, 2003)This thesis studies the application of the wavelet filter bank (WFB) in perceptual audio coding by providing brief overviews of perceptual coding, psychoacoustics, wavelet theory, and existing wavelet coding algorithms. ... -
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 ... -
Waves: A Collaborative Navigation Technique for Large Interactive Surfaces
(University of Waterloo, 2014-08-21)Digital tables offer the possibility of performing collaborative tasks where two or more people can share artifacts in the same virtual space. However, most interactive methods of navigating through virtual space most ... -
We Belong With the Water: Mobility, temporal habitation, rituals, and other 'incidental' elements surrounding fish harvesting traditions of Indigenous communities in Southern Georgian Bay - A Graphic Novel
(University of Waterloo, 2020-06-24)For over 200 years, the delineation of the land and subsequent colonial settlement throughout Canada has subjugated and removed Indigenous presence from the land. This includes their constructions, tools, and laws connected ... -
Weak invariant simulation and analysis of parameterized networks
(University of Waterloo, 2014-12-11)Multi-process networks figure in many engineering applications such as communication networks, transportation networks, manufacturing and logistic systems, and computer hardware and software. Parameterized discrete event ... -
Weakly Supervised Learning Algorithms and an Application to Electromyography
(University of Waterloo, 2014-06-23)In the standard machine learning framework, training data is assumed to be fully supervised. However, collecting fully labelled data is not always easy. Due to cost, time, effort or other types of constraints, requiring ... -
Wear and Boundary Lubrication in Modular Total Knee Replacements
(University of Waterloo, 2009-02-17)Wear of the polyethylene (PE) bearing surface and wear particle-induced osteolysis (bone resorption) can lead to failure of modular total knee replacements and make expensive revision surgery necessary. Gamma-in-air ... -
Wear of PEEK All-Polymer Articulations for Cervical Spinal Disc Arthroplasty
(University of Waterloo, 2009-01-23)The conventional treatment for degenerative disc disease (DDD) and disc herniation is spinal fusion, a process consisting of fusing two segments of the spine together. Arthroplasty treatments that preserve the natural ... -
Wearable RF Resonant Gaseous Chemical Sensor Array
(University of Waterloo, 2015-05-01)Biomarker detection is a major engineering goal that enables numerous applications in the fields of biomedical and law enforcement. By monitoring the conditions of the subject with a dedicated biomarker detection system, ... -
Wearable Tactile Pressure Sensing for Compression Garments and Control of Active Compression Devices
(University of Waterloo, 2016-01-22)Compression garments on the lower limbs have been used for the treatment of venous deficiencies for centuries. More recently, healthy athletes have used similar garments for an edge in performance and improved recovery ... -
Web Based Automatic Tool Path Planning Strategy for Complex Sculptured Surfaces
(University of Waterloo, 2010-06-16)Over the past few years, manufacturing companies have had to deal with an increasing demand for feature-rich products at low costs. The pressures exerted on their existing manufacturing processes have lead manufacturers ... -
Web Tasking: An Investigation of End User Interaction for the Ideal Control Metaphor
(University of Waterloo, 2016-05-02)Users are finding multiple ways to utilize web applications (apps) outside of their typical self-contained purposes, resulting in an increasing need to connect apps together. This connectivity can be achieved through web ... -
