Enriched mixed finite element models for dynamic analysis of continuous and fractured porous media
(Elsevier, 2019-01-01)Enriched Finite Element Models are presented to more accurately investigate the transient and wave propagation responses of continuous and fractured porous media based on mixture theory. Firstly, the Generalized Finite ... -
Enrichment and activity of comammox Nitrospira from the rotating biological contactors of a municipal wastewater treatment system
(University of Waterloo, 2021-02-05)Nitrification, the biological conversion of ammonia to nitrate, via nitrite, is an important process in both natural and engineered systems. Nitrification within wastewater treatment plants (WWTPs) is necessary because ... -
Entanglement Entropy in Quantum Gravity
(University of Waterloo, 2008-05-22)We study a proposed statistical explanation for the Bekenstein-Hawking entropy of a black hole in which entropy arises quantum-mechanically as a result of entanglement. Arguments for the identification of black hole entropy ... -
Entanglement Entropy of Scalar Fields in Causal Set Theory
(University of Waterloo, 2017-08-15)Entanglement entropy is now widely accepted as having deep connections with quantum gravity. It is therefore desirable to understand it in the context of causal sets, especially since they provide the UV cutoff needed to ... -
Entanglement Harvesting and Divergences in Unruh-DeWitt Detector Pairs
(University of Waterloo, 2017-08-28)We analyze correlations between pairs of detectors quadratically coupled to real and complex scalar bosonic fields in 3+1 dimensions. This is a first step toward studying the entanglement structure of the fermionic ... -
Entanglement in Non-inertial Frames
(University of Waterloo, 2008-09-19)This thesis considers entanglement, an important resource for quantum information processing tasks, while taking into account the theory of relativity. Not only is this a more complete description of quantum information, ... -
Entanglement in single-shot quantum channel discrimination
(University of Waterloo, 2018-08-30)Single-shot quantum channel discrimination is the fundamental task of determining, given only a single use, which of two known quantum channels is acting on a system. In this thesis we investigate the well-known phenomenon ... -
Entanglement quantification and quantum benchmarking of optical communication devices
(University of Waterloo, 2012-04-27)In this thesis, we develop a number of operational tests and tools for benchmarking the quantum nature of optical quantum communication devices. Using the laws of quantum physics, ideal quantum devices can fundamentally ... -
Entangling qubit registers via many-body states of ultracold atoms
(American Physical Society, 2016-04-25)Inspired by the experimental measurement of the Rényi entanglement entropy in a lattice of ultracold atoms by Islam et al. [Nature (London) 528, 77 (2015)], we propose a method to entangle two spatially separated qubits ... -
Entire Solutions to Dirichlet Type Problems
(University of Waterloo, 2007-08-02)In this thesis, we examined some Dirichlet type problems of the form: \begin{eqnarray*} \triangle u & = & 0\ {\rm in\ } \mathbb{R}^n \\ u & = & f\ {\rm on\ } \psi = 0, \end{eqnarray*} and we were particularly ... -
Entity Matching and Disambiguation Across Multiple Knowledge Graphs
(University of Waterloo, 2019-06-10)Knowledge graphs are considered an important representation that lie between free text on one hand and fully-structured relational data on the other. Knowledge graphs are a back-bone of many applications on the Web. With ... -
Entrepreneurship and the intersection of work, leisure, and family

Entropic Matroids and Their Representation
(Multidisciplinary Digital Publishing Institute, 2019)This paper investigates entropic matroids, that is, matroids whose rank function is given as the Shannon entropy of random variables. In particular, we consider p-entropic matroids, for which the random variables each have ... -
Entropic Segregation at Surfaces of Polymer Melts
(University of Waterloo, 2018-05-04)Throughout recent years, polymers have been one of the most widely used materials in industry due to their suitability to a vast variety of fields from construction to biomedical and technological utilities. Their extensive ... -
Entropic segregation of short polymers to the surface of a polydisperse melt
(Springer, 2017)Chain ends are known to have an entropic preference for the surface of a polymer melt, which in turn is expected to cause the short chains of a polydisperse melt to segregate to the surface. Here, we examine this entropic ... -
Entropically Driven Formation of Hierarchically Ordered Nanocomposites
(American Physical Society, 2002)Using theoretical models, we undertake the first investigation into the rich behavior that emerges when binary particle mixtures are blended with microphase-separating copolymers. We isolate an example of coupled self-assembly ... -
Entropy and Graphs
(University of Waterloo, 2014-01-23)The entropy of a graph is a functional depending both on the graph itself and on a probability distribution on its vertex set. This graph functional originated from the problem of source coding in information theory and ... -
Entropy-based aggregate posterior alignment techniques for deterministic autoencoders and implications for adversarial examples
(University of Waterloo, 2020-08-27)We present results obtained in the context of generative neural models — specifically autoencoders — utilizing standard results from coding theory. The methods are fairly elementary in principle, yet, combined with the ... -
Entropy-based Demand Splits in a Hospital-Warehouse Profit Center
(University of Waterloo, 2014-08-11)Financial pressures on healthcare industry in the United States and elsewhere have forced the industry to address their supply costs, their fastest growing cost sector currently comprising over 40 % of their total spend. ... -
Entropy-Stable Positivity-Preserving Schemes for Multiphase Flows
(University of Waterloo, 2024-01-22)High-intensity focused ultrasound is a promising non-invasive medical technology that has been successfully used to ablate tumors, as well as in the treatment of other conditions. Researchers believe high-intensity focused ...
