On the Optimal Transmission Strategies for Sources without Channel State Information
(University of Waterloo, 2011-09-30)With the growth of multimedia services, it is essential to find new transmission schemes to support higher data rates in wireless networks. In this thesis, we study networks in which the Channel State Information (CSI) ... -
On the Orchestration and Provisioning of NFV-enabled Multicast Services
(University of Waterloo, 2020-05-14)The paradigm of network function virtualization (NFV) with the support of software-defined networking has emerged as a prominent approach to foster innovation in the networking field and reduce the complexity involved in ... -
On the orientation of hypergraphs
(University of Waterloo, 2011-01-13)This is an expository thesis. In this thesis we study out-orientations of hypergraphs, where every hyperarc has one tail vertex. We study hypergraphs that admit out-orientations covering supermodular-type connectivity ... -
On The Origin of Cold Molecular Gas In Giant Elliptical Galaxies
(University of Waterloo, 2017-01-23)We present an analysis of 55 giant elliptical galaxies residing in the centre of clusters and groups to investigate the origin of H₂ molecular gas centrally located in these galaxies. Using Chandra X-ray data and IRAM 30m ... -
On the Path to Material Re-Use: Navigating the complexity of material sustainability for architectural practice
(University of Waterloo, 2016-09-20)The aim of this thesis was to understand how to define sustainability holistically, and how architecture can contribute to holistic sustainability by way of its material form. I conducted a literature review of definitions ... -
On the Performance Analysis of Cooperative Vehicular Communication
(University of Waterloo, 2012-02-08)Vehicular networking is envisioned to be a key technology area for significant growth in the coming years. Although the expectations for this emerging technology are set very high, many practical aspects remain still ... -
On the Perpetuation of Ignorance: System Dependence, System Justification, and the Motivated Avoidance of Socio-Political Information
(University of Waterloo, 2012-06-28)How do people cope when they feel uninformed or unable to understand important social issues, such as the environment, energy concerns, or the economy? One would intuitively expect that a lack of knowledge would motivate ... -
On the planar flow development and structural loading of cylinders with circular fins in cross-flow
(University of Waterloo, 2015-05-14)Finned cylinders are commonly encountered in the design of heat exchangers. Critical to the design and performance of a heat exchanger are the mean and fluctuating loading on the tubes, as they relate to pressure losses ... -
On the Polyhedral Lift-and-Project Rank Conjecture for the Fractional Stable Set Polytope
(University of Waterloo, 2008-01-16)In this thesis, we study the behaviour of Lovasz and Schrijver's lift-and-project operators N and N_0 while being applied recursively to the fractional stable set polytope of a graph. We focus on two related conjectures ... -
On the Potential Use of Small Scale Fire Tests for Screening Steiner Tunnel Results for Spray Foam Insulation
(University of Waterloo, 2013-05-21)The goal of this study is to assess the potential of using bench-scale fire testing to screen materials for the Steiner tunnel fire test. It is hypothesized that the chemical and physical changes made to a material to ... -
On the Power and Limitations of Shallow Quantum Circuits
(University of Waterloo, 2022-09-01)Constant-depth quantum circuits, or shallow quantum circuits, have been shown to exhibit behavior that is uniquely quantum. This thesis explores the power and limitations of constant-depth quantum circuits, in particular ... -
On the power of interleaved low-depth quantum and classical circuits
(University of Waterloo, 2022-09-26)Low-depth quantum circuits are a well-suited model for near-term quantum devices, given short coherence times and noisy gate operations, making it pivotal to examine their computational power. It was already known as early ... -
On The Precipice Of Change
(University of Waterloo, 2014-09-18)Situated centrally, two blocks north of People’s Square, in Zhabei District of Shanghai, China, Sihang Warehouse is a place steeped in time. In 1937, during the Sino-Japanese War, when this building was still one of ... -
On the Prediction of Gas Hold-up in Ebullated Bed Reactors
(University of Waterloo, 2019-09-19)Commercial ebullated bed reactors (EBRs) are three-phase fluidized bed systems used for hydroprocessing (upgrading) of bitumen, a major Canadian resource. The objective of this thesis is to improve the understanding of the ... -
On the Properties and Structure of Bordered Words and Generalizations
(University of Waterloo, 2022-10-12)Combinatorics on words is a field of mathematics and theoretical computer science that is concerned with sequences of symbols called words, or strings. One class of words that are ubiquitous in combinatorics on words, ... -
On the Relation between Quantum Discord and Purified Entanglement
(University of Waterloo, 2013-08-30)In this thesis, I study bipartite discord between A and B in terms of the structure formed by the bipartite and tripartite entanglement found in the purified system ABC. I find that discord manifests itself only when there ... -
On the Relationship between Conjugate Gradient and Optimal First-Order Methods for Convex Optimization
(University of Waterloo, 2014-01-23)In a series of work initiated by Nemirovsky and Yudin, and later extended by Nesterov, first-order algorithms for unconstrained minimization with optimal theoretical complexity bound have been proposed. On the other hand, ... -
