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 ... -
Executable Model Synthesis and Property Validation for Message Sequence Chart Specifications
(University of Waterloo, 2000)Message sequence charts (MSC’s) are a formal language for the specification of scenarios in concurrent real-time systems. The thesis addresses the synthesis of executable object-oriented design-time models from MSC ... -
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 ... -
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 ... -
Load Balancing Schemes for Distributed Real-Time Interactive Virtual World Simulations
(University of Waterloo, 2000)Over the last several years, there has been tremendous growth in online gaming (i. e. playing games over the internet). The Massively Multiplayer Online Role Playing Game (MMORPG) is one type of online game. An ... -
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 ... -
Stabilization of Discrete-time Systems With Bounded Control Inputs
(University of Waterloo, 2000)In this paper we examine the stabilization of LTI discrete-time systems with control input constraints in the form of saturation nonlinearities. This kind of constraint is usually introduced to simulate the effect of ... -
Finite Field Multiplier Architectures for Cryptographic Applications
(University of Waterloo, 2000)Security issues have started to play an important role in the wireless communication and computer networks due to the migration of commerce practices to the electronic medium. The deployment of security procedures requires ... -
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 ... -
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 ... -
Mixed signal design flow, a mixed signal PLL case study
(University of Waterloo, 2001)Mixed-signal designs are becoming more and more complex every day. In order to adapt to the new market requirements, a formal process for design and verification of mixed signal systems i. e. top-down design and ... -
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. ... -
CDMA Channel Selection Using Switched Capacitor Technique
(University of Waterloo, 2001)CDMA channel selection requires sharp as well as wide-band Filtering. SAW Filters which have been used for this purpose are only available in IF range. In direct conversion receivers this has to be done at low frequencies. ... -
Circuit Model Parameter Extraction and Optimization for Microwave Filters
(University of Waterloo, 2002)This thesis presents a method for parameter extraction of circuit elements from microwave filters. This diagnosis method can be applied to a sufficiently large number of filters and it can also be used in conjunction ... -
Design and Analysis of Intelligent Fuzzy Tension Controllers for Rolling Mills
(University of Waterloo, 2002)This thesis presents a fuzzy logic controller aimed at maintaining constant tension between two adjacent stands in tandem rolling mills. The fuzzy tension controller monitors tension variation by resorting to electric ... -
Split-Domain TCP-Friendly Protocol For MPEG-4 Adaptive Rate Video Streaming Over 3G Networks
(University of Waterloo, 2002)The imminent inception of third-generation (3G) mobile communication networks offers an unprecedented opportunity for the development of video streaming applications through wireless Internet access. Different design ... -
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 ... -
Phosphor Coated UV-Responsive CCD Image Sensors
(University of Waterloo, 2002)Typical CCD image sensors are not sensitive to Ultra-Violet (UV) radiation, because the UV photons have a penetration depth of 2nm in the ~1µm thick polysilicon gate material. An inorganic phosphor coating was ... -
