On Non-Binary Constellations for Channel Encoded Physical Layer Network Coding
(University of Waterloo, 2012-04-23)This thesis investigates channel-coded physical layer network coding, in which the relay directly transforms the noisy superimposed channel-coded packets received from the two end nodes, to the network-coded combination ... -
On Nonlinear Time-Invariant Behavioural Models of Power Transistors Used in the Computer-Aided Design of Power Amplifiers
(University of Waterloo, 2023-06-01)The Radio Frequency (RF) Power Amplifier (PA) is the main consumer of power in a wireless transmitter. Energy efficient PA design aided with circuit simulation tools requires accurate nonlinear models of the power transistors ... -
On Obsessions: A Phenomenology of Doubt, Images, and the Obsessive-Compulsive Chronological Structure in Obsessive-Compulsive Disorder
(University of Waterloo, 2020-04-22)Obsessive-compulsive disorder (OCD) is a debilitating disorder that is heterogeneous in presentation and difficult to treat. Nearly half of treatment-seeking individuals do not benefit fully from therapy, and success rates ... -
On Occupancy Based Randomized Load Balancing for Large Systems with General Distributions
(University of Waterloo, 2019-11-13)Multi-server architectures are ubiquitous in today's information infrastructure whether for supporting cloud services, web servers, or for distributed storage. The performance of multi-server systems is highly dependent ... -
On Optimal Online Policies in Energy Harvesting Communication Systems: Effects of Quality of Service and Battery Requirements
(University of Waterloo, 2016-04-27)We study the problem of finding optimal transmission policies in a point-to-point energy harvesting communication system with continuous energy arrivals in causal setting. In particular, we investigate bounds on the long-term ... -
On Optimizing Traffic Distribution for Clusters of Network Intrusion Detection and Prevention Systems
(University of Waterloo, 2008-09-02)To address the overload conditions caused by the increasing network traffic volume, recent literature in the network intrusion detection and prevention field has proposed the use of clusters of network intrusion detection ... -
On Optimum Conventional Quantization for Source Coding with Side Information at the Decoder
(University of Waterloo, 2007-09-26)In many scenarios, side information naturally exists in point-to-point communications. Although side information can be present in the encoder and/or decoder and thus yield several cases, the most important case that worths ... -
On Pairing-Based Signature and Aggregate Signature Schemes
(University of Waterloo, 2009-01-21)In 2001, Boneh, Lynn, and Shacham presented a pairing-based signature scheme known as the BLS signature scheme. In 2003, Boneh, Gentry, Lynn, and Shacham presented the first aggregate signature scheme called the BGLS ... -
On Parallel Computation of Large Smooth-Degree Isogeny
(University of Waterloo, 2023-08-04)The computation of large smooth-degree isogenies is considered to be the most time-consuming task in isogeny-based cryptosystems and, to this end, recently several proposals have been made to speed it up. For implementation ... -
On Periodic Correlation of Binary Sequences
(University of Waterloo, 2007-01-04)A (periodic) correlation function is an important measure to evaluate the effectiveness of pseudorandom sequences. In practice, the sequences are required to have the impulse-like autocorrelation function. Also, crosscorrelation ... -
On Perturbative Methods in Spectral Geometry
(University of Waterloo, 2017-08-28)The goal of spectral geometry is to establish how much information about the geometry of compact Riemannian manifolds is contained in the spectra of natural differential operators, especially Laplacians, defined on them. ... -
On Polynomial-time Path-following Interior-point Methods with Local Superlinear Convergence
(University of Waterloo, 2016-09-30)Interior-point methods provide one of the most popular ways of solving convex optimization problems. Two advantages of modern interior-point methods over other approaches are: (1) robust global convergence, and (2) the ... -
On primal-dual interior-point algorithms for convex optimisation
(2015-09-29)This thesis studies the theory and implementation of interior-point methods for convex optimisation. A number of important problems from mathematics and engineering can be cast naturally as convex optimisation ... -

On Prime-Order Elliptic Curves with Embedding Degrees 3, 4 and 6
(University of Waterloo, 2007-01-22)Bilinear pairings on elliptic curves have many cryptographic applications such as identity based encryption, one-round three-party key agreement protocols, and short signature schemes. The elliptic curves which are ... -
On Ranking the Relative Importance of Nodes in Physical Distribution Networks
(University of Waterloo, 2011-05-24)Physical distribution networks are integral parts of modern supply chains. When faced with a question of which node in a network is more important, cost immediately jumps to mind. However, in a world of uncertainty, there ... -
On Reading, Anxiety and Water: A Sanatorium on the Toronto Portlands
(University of Waterloo, 2004)The thesis is comprised of three essays and a design project of a fictional sanatorium and attached public park for the Toronto Portlands. The project basically pursues a sense of architectural place that is most clearly ... -
On Realistic Errors in Quantum Computers
(University of Waterloo, 2021-05-27)In this thesis, we are concerned with the problem of characterizing noise associated with implementations of quantum circuits. We first explore the notion of error rates of quantum circuits and argue that the semantic ... -
On Reconfiguration Problems: Structure and Tractability
(University of Waterloo, 2015-02-18)Given an n-vertex graph G and two vertices s and t in G, determining whether there exists a path and computing the length of the shortest path between s and t are two of the most fundamental graph problems. In the classical ... -
On Resurfacing: A Case for a Cultural Renaissance
(University of Waterloo, 2013-01-25)Globalization and the advancement of technology have made the world smaller. Boundaries that define nations and nationalities have blurred and the resulting sense of displacement has undermined assumptions of identity and ...
