On the spectrum of the Sylvester-Rosenblum operator acting on triangular algebras
(Ele-Math, 2020)Let A and B be algebras and M be an A -B-bimodule. For A ∈ A , B ∈B, we define the Sylvester-Rosenblum operator τA,B :M →M via τA,B(M) = AM+MB for all M ∈ M . We investigate the spectrum of τA,B in three settings, namely: ... -
On the Strongly Connected Components of Random Directed Graphs with Given Degree Sequences
(University of Waterloo, 2016-08-24)A strongly connected component of a directed graph G is a maximal subgraph H of G such that for each pair of vertices u and v in H, there is a directed path from u to v and a directed path from v to u in H. A strongly ... -
On the structure of invertible elements in certain Fourier-Stieltjes algebras
(University of Waterloo, 2021-08-27)Let $G$ be a locally compact group. The Fourier-Stieltjes and Fourier algebras, $B(G)$ and $A(G)$ are defined by Eymard to act as dual objects of the measure and group algebras, $M(G)$ and $L^1(G)$, in a sense generalizing ... -
On the Structure of Nonnegative Semigroups of Matrices
(University of Waterloo, 2009-08-18)The results presented here are concerned with questions of decomposability of multiplicative semigroups of matrices with nonnegative entries. Chapter 1 covers some preliminary results which become useful in the remainder ... -
On the Succinct Representation of Equivalence Classes
(University of Waterloo, 2014-12-17)Given a set of n elements that are partitioned into equivalence classes, we study the problem of assigning unique labels to these elements in order to support the query that asks whether the elements corresponding to two ... -

On the Techniques for Efficient Sampling, Uncertainty Quantification and Robust Control of Stochastic Multiscale Systems
(University of Waterloo, 2020-08-25)In order to better understand and leverage natural phenomena to design materials and devices (e.g. biomedical coatings, catalytic reactors, thin conductive films for microprocessors, etc.), stochastic multiscale models ... -
On the theoretical importance of distinguishing between intentional and unintentional types of Mind Wandering
(University of Waterloo, 2015-07-22)When introduced to mainstream psychological research nearly a decade ago, mind wandering was defined as unintentional, internally-focused thought. The requirement of an absence of intention was critical in terms of the ... -
On the TVD property of second order methods for 2D scalar conservation laws
(arXiv, 2021-10-05)The total variation diminishing (TVD) property is an important tool for ensuring nonlinear stability and convergence of numerical solutions of one-dimensional scalar conservation laws. However, it proved to be challenging ... -
On the universality of mass inflation inside black holes

On the Use of Directed Moves for Placement in VLSI CAD
(University of Waterloo, 2009-07-31)Search-based placement methods have long been used for placing integrated circuits targeting the field programmable gate array (FPGA) and standard cell design styles. Such methods offer the potential for high-quality ... -
On the Use of MODIS for Lake and Land Surface Temperature Investigations in the Regions of Great Bear Lake and Great Slave Lake, N.W.T.
(University of Waterloo, 2011-08-19)Lake surface temperature (LSTlake) can be obtained and studied in different ways: using in situ measurements, satellite imagery and modeling. Collecting spatially representative in situ data over lakes, especially for large ... -
On the use of physical boundary conditions for two-phase flow simulations: Integration of control feedback
(Elsevier, 2018-10-04)The sensitivity of two-phase flow simulations using the Euler–Euler model on the inlet boundary conditions (BCs) is studied. Specifically, the physical relevance of Dirichlet uniform inlet velocity BCs is studied which are ... -
On the Utility of Adding An Abstract Domain and Attribute Paths to SQL
(University of Waterloo, 2018-04-30)Albeit its popularity today, RDBMS and the relational model still have many limitations. For example, one needs to pay premature attention to naming issues in the schema designing phase; and the syntax for conjunctive ... -
On the Verge: Activating Public Space in the Periphery
(University of Waterloo, 2009-06-19)This thesis examines the suburban verge’s latent potential as an alternative public space. It is located between the boundaries of private properties and public streets, where territorial boundaries and ownership are ... -
On Tolerant Testing and Tolerant Junta Testing
(University of Waterloo, 2020-07-08)Over the past few decades property testing has became an active field of study in theoretical computer science. The algorithmic task is to determine, given access to an unknown large object (e.g., function, graph, probability ... -
On Transcendence of Irrationals with Non-eventually Periodic b-adic Expansions
(University of Waterloo, 2010-05-18)It is known that almost all numbers are transcendental in the sense of Lebesgue measure. However there is no simple rule to separate transcendental numbers from algebraic numbers. Today research in this direction is about ... -
On Two Combinatorial Optimization Problems in Graphs: Grid Domination and Robustness
(University of Waterloo, 2013-08-30)In this thesis, we study two problems in combinatorial optimization, the dominating set problem and the robustness problem. In the first half of the thesis, we focus on the dominating set problem in grid graphs and present ... -
