On the Effects of Disfluency in Complex Cognitive Tasks
(University of Waterloo, 2017-05-10)While much previous research has suggested that decreased transcription fluency has a detrimental effect on writing, there is recent evidence that decreased fluency can actually benefit cognitive processing. Across a series ... -
On the effects of offloading memory on memory performance
(University of Waterloo, 2020-07-06)The use of external aids to reduce cognitive demands is known as cognitive offloading. I present five preregistered experiments aimed at better understanding the effects of cognitive offloading on memory performance. The ... -
On the Efficiency and Security of Cryptographic Pairings
(University of Waterloo, 2012-12-19)Pairing-based cryptography has been employed to obtain several advantageous cryptographic protocols. In particular, there exist several identity-based variants of common cryptographic schemes. The computation of a single ... -
On The Engineering of a Stable Force-Directed Placer
(University of Waterloo, 2004)Analytic and force-directed placement methods that simultaneously minimize wire length and spread cells are receiving renewed attention from both academia and industry. However, these methods are by no means trivial to ... -
On the Enhancement of the Localization of Autonomous Mobile Platforms
(University of Waterloo, 2020-08-27)The focus of many industrial and research entities on achieving full robotic autonomy increased in the past few years. In order to achieve full robotic autonomy, a fundamental problem is the localization, which is the ... -
On the Erdös-Turán conjecture and related results
(University of Waterloo, 2011-08-29)The Erdös-Turán Conjecture, posed in 1941 in, states that if a subset B of natural numbers is such that every positive integer n can be written as the sum of a bounded number of terms from B, then the number of such ... -
On the evaluation of quantum instruments with a consideration to measurements in trapped ion systems
(University of Waterloo, 2022-12-20)Trapped ion chains have shown promise in their application as quantum simulators. However, the close proximity of ions in the trap leads to operations such as state detection causing loss of coherence of other ions due to ... -
On the Evolutionary Design of Quantum Circuits
(University of Waterloo, 2005)The goal of this work is to understand the application of the evolutionary programming approach to the problem of quantum circuit design. This problem is motivated by the following observations: <ul> <li>In order to ... -
On the Excluded Minors for Dyadic Matroids
(University of Waterloo, 2019-01-17)The study of the class of dyadic matroids, the matroids representable over both $GF(3)$ and $GF(5)$, is a natural step to finding the excluded minors for $GF(5)$-representability. In this thesis we characterize the ternary ... -
On the experimental design of the material microstructures
(University of Waterloo, 2014-05-05)The design techniques of the components on the macro level are established in the scientific community, however are far behind from the real material performance limits. To obtain those limits, the deeper understanding of ... -
On the Extrema of Functions in the Takagi Class
(University of Waterloo, 2019-01-23)The Takagi class is a class of fractal functions on the unit interval generalizing the celebrated Takagi function. In this thesis, we study the extrema of these functions. This is a problem that goes back to J.-P. Kahane ... -
On the Fire Performance of Exterior Wall Materials and Assemblies
(University of Waterloo, 2022-06-09)Recent attempts at combating climate change have urged the developers, public authorities, and other building stakeholders to employ enhanced energy conservation initiatives as Canada’s building sector accounts for 13% of ... -
On the Geometry of IFS Fractals and its Applications
(University of Waterloo, 2014-01-23)Visually complex objects with infinitesimally fine features, naturally call for mathematical representations. The geometrical property of self-similarity - the whole similar to its parts - when iterated to infinity generates ... -
On the Hardness of the Quantum Separability Problem and the Global Power of Locally Invariant Unitary Operations
(University of Waterloo, 2008-09-18)Given a bipartite density matrix ρ of a quantum state, the Quantum Separability problem (QUSEP) asks — is ρ entangled, or separable? In this thesis, we first strengthen Gurvits’ 2003 NP-hardness result for QUSEP by showing ... -
ON THE IMPLICATIONS OF VARIOUS APPROACHES TO GROUNDWATER SOURCE PROTECTION
(University of Waterloo, 2008-06-22)Protection of groundwater sources has become an important issue in Canada. Over the last decade many approaches to the protection of groundwater sources have evolved. Some approaches provide qualitative information while ... -
On the Importance of Infrastructure-Awareness in Large-Scale Distributed Storage Systems
(University of Waterloo, 2021-01-08)Big data applications put significant latency and throughput demands on distributed storage systems. Meeting these demands requires storage systems to use a significant amount of infrastructure resources, such as network ... -
On the Influence of the Through-Thickness Strain Gradients for Characterization of Formability and Fracture of Sheet Metal Alloys
(University of Waterloo, 2019-01-25)The main focus of this thesis is to investigate the effect of through-thickness strain gradient on sheet metal formability. Current technology for formability analysis has relied upon deformation modes of in-plane stretching ... -
On the Integrality Gap of Directed Steiner Tree Problem
(University of Waterloo, 2014-05-27)In the Directed Steiner Tree problem, we are given a directed graph G = (V,E) with edge costs, a root vertex r ∈ V, and a terminal set X ⊆ V . The goal is to find the cheapest subset of edges that contains an r-t path for ... -

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.
