Accounting for the Effects of Power System Controllers and Stability on Power Dispatch and Electricity Market Prices
(University of Waterloo, 2005)Recently, the widespread use of power system controllers, such as PSS and FACTS controllers, has led to the analysis of their effect on the overall stability of power systems. Many studies have been conducted to allocate ... -
Achieving Fairness in 802.11-Based Multi-channel Wireless Mesh Networks
(University of Waterloo, 2006)Multi-hop wireless networks based on 802. 11 are being used more widely as an alternative technology for last-mile broadband Internet access. Their benefits include ease of deployment and lower cost. Such networks are ... -
Achieving Scalable, Exhaustive Network Data Processing by Exploiting Parallelism
(University of Waterloo, 2004)Telecommunications companies (telcos) and Internet Service Providers (ISPs) monitor the traffic passing through their networks for the purposes of network evaluation and planning for future growth. Most monitoring ... -
Adaptive Fractal and Wavelet Image Denoising
(University of Waterloo, 2004)The need for image enhancement and restoration is encountered in many practical applications. For instance, distortion due to additive white Gaussian noise (AWGN) can be caused by poor quality image acquisition, images ... -
Alternative Electricity Market Systems for Energy and Reserves using Stochastic Optimization
(University of Waterloo, 2005)This thesis presents a model that simulates and solves power system dispatch problems utilizing stochastic linear programming. The model features the ability to handle single period, multiple bus, linear DC approximated ... -
Alternative Models to Analyze Market Power and Financial Transmission Rights in Electricity Markets
(University of Waterloo, 2005)One of the main concerns with the introduction of competition in the power sector is the strategic behaviour of market participants. Computable models of strategic behaviour are becoming increasingly important to ... -
Analysis and Design of Lossless Bi-level Image Coding Systems
(University of Waterloo, 2000)Lossless image coding deals with the problem of representing an image with a minimum number of binary bits from which the original image can be fully recovered without any loss of information. Most lossless image coding ... -
Analysis of the Asymptotic Performance of Turbo Codes
(University of Waterloo, 2006)Battail [1989] shows that an appropriate criterion for the design of long block codes is the closeness of the normalized weight distribution to a Gaussian distribution. A subsequent work shows that iterated product of ... -
Analysis of the Deep Sub-Micron a-Si:H Thin Film Transistors
(University of Waterloo, 2005)The recent developments of high resolution flat panel imagers have prompted interests in fabricating smaller on-pixel transistors to obtain higher fill factor and faster speed. This thesis presents fabrication and modeling ... -
An Analysis of Wireless High-speed Data Services for Cellular CDMA Systems
(University of Waterloo, 2002)The interest in the development of wireless high-speed data services is in response to the strong market demand for high-speed wireless Internet access. Current standards aim at delivering a peak data rate greater than ... -
Analytical Methods for the Performance Evaluation of Binary Linear Block Codes
(University of Waterloo, 2000)The modeling of the soft-output decoding of a binary linear block code using a Binary Phase Shift Keying (BPSK) modulation system (with reduced noise power) is the main focus of this work. With this model, it is possible ... -
Application of Non-linear Optimization Techniques in Wireless Telecommunication Systems
(University of Waterloo, 2006)Non-linear programming has been extensively used in wireless telecommunication systems design. An important criterion in optimization is the minimization of mean square error. This thesis examines two applications: ... -
Application of Turbo-Codes in Digital Communications
(University of Waterloo, 2001)This thesis aims at providing results and insight towards the application of turbo-codes in digital communication systems, mainly in three parts. The first part considers systems of combined turbo-code and modulation. ... -
An Architecture for the AES-GCM Security Standard
(University of Waterloo, 2006)The forth recommendation of symmetric block cipher mode of operation SP800-38D, <em>Galois/Counter Mode of Operation</em> (GCM) was developed by David A McGrew and John Viega. GCM uses an approved symmetric key block ... -
An Automated Malignant Tumour Localization Algorithm for Prostate Cancer Detection in Trans-rectal Ultrasound Images
(University of Waterloo, 2004)The goal of this thesis is to design, implement and evaluate an automated algorithm to detect cancerous tissues and segment the malignant tumour in ultrasound images of the prostate. To accomplish this goal, first, the ... -
Automating Radiotherapy: Parameterizations of Sensor Time Delay Compensators and the Separation Principle
(University of Waterloo, 2006)Motivated by recent research to automate radiotherapy, this thesis looks into feedback control problems where the feedback sensor imposes considerable time delay. The use of an asymptotic estimator is considered as a ... -
Bit Serial Systolic Architectures for Multiplicative Inversion and Division over GF(2<sup>m</sup>)
