On the local positivity of line bundles on algebraic surfaces
(University of Waterloo, 2015-01-09)In this thesis, we define a measure for how `positive' an effective line bundle is at a point on a variety, and prove that it is linear on the numerically effective subcone on a smooth, complete, toric surface. -
On the Maintenance Costs of Formal Software Requirements Specification Written in the Software Cost Reduction and in the Real-time Unified Modeling Language Notations
(University of Waterloo, 2005)A formal specification language used during the requirements phase can reduce errors and rework, but formal specifications are regarded as expensive to maintain, discouraging their adoption. This work presents a ... -
On the Manifold: Representing Geometry in C++ for State Estimation
(University of Waterloo, 2018-12-19)Manipulating geometric objects is central to state estimation problems in robotics. Typical algorithms must optimize over non-Euclidean states, such as rigid transformations on the SE(3) manifold, and handle measurements ... -
On the mnemonic benefits of drawing
(University of Waterloo, 2017-08-02)Researchers have long sought to explore means through which the amount, and quality of information one is able to remember can be improved. Attention has been paid variously to multimodal encoding, visual learning, and ... -
On the Modelling of Hyperspectral Light and Skin Interactions and the Simulation of Skin Appearance Changes Due to Tanning
(University of Waterloo, 2016-01-07)The distinctive visual attributes of human skin are largely determined by its interactions with light across different spectral domains. Accordingly, the modelling of these interactions has been the object of extensive ... -
On the Modular Theory of von Neumann Algebras
(University of Waterloo, 2010-09-17)The purpose of this thesis is to provide an exposition of the \textit{modular theory} of von Neumann algebras. The motivation of the theory is to classify and describe von Neumann algebras which do not admit a trace, and ... -
On the Near-Optimality of List Scheduling Heuristics for Local and Global Instruction Scheduling
(University of Waterloo, 2006)Modern architectures allow multiple instructions to be issued at once and have other complex features. To account for this, compilers perform instruction scheduling after generating the output code. The instruction ... -
On the Non-Orthogonal Layered Broadcast Codes in Cooperative Wireless Networks
(University of Waterloo, 2020-05-20)A multi-fold increase in spectral efficiency and throughput are envisioned in the fifth generation of cellular networks to meet the requirements of International Telecommunication Union (ITU) IMT-2020 on massive connectivity ... -
On the Optical Monitoring of Anemia Severity Levels
(University of Waterloo, 2015-08-13)Anemia is a prevalent medical condition that seriously a ects millions of people all over the world. In many regions, not only its initial detection, but also its monitoring are hindered by the limited access to laboratory ... -
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 ... -
