UNiS: A User-space Non-intrusive Workflow-aware Virtual Network Function Scheduler
(University of Waterloo, 2019-01-16)Network Function Virtualization (NFV) has gained a significant research interest in both academia and industry since its inception in the late 2012. One of the key research issues in NFV is the development of systems for ... -
Unitary Correlation Sets and their Applications
(University of Waterloo, 2019-07-04)We relate Connes' embedding problem in operator algebras to the Brown algebra Unc(n), which is defined as the universal unital C*-algebra generated by the entries of an n x n unitary matrix. In particular, we show that the ... -
Universal bounds for positive matrix semigroups
(Polish Academy of Sciences, 2016)We show that any compact semigroup of positive n×n matrices is similar (via a positive diagonal similarity) to a semigroup bounded by n√. We give examples to show this bound is best possible. We also consider the effect ... -
Universal Database System Analysis for Insight and Adaptivity
(University of Waterloo, 2022-12-13)Database systems are ubiquitous; they serve as the cornerstone of modern application infrastructure due to their efficient data access and storage. Database systems are commonly deployed in a wide range of environments, from ... -
Universe Beyond Inflation and ΛCDM
(University of Waterloo, 2021-09-09)The current paradigm of universe, $\Lambda CDM$ model with an early phase of inflation, has been quite successful in describing our universe in a simple manner, yet matching well with the observational evidence. This model ... -
The Unobserved Waiting Customer Approximation
(Springer, 2021-06-02)We introduce a new approximation procedure to improve the accuracy of matrix analytic methods when using truncated queueing models to analyse infinite buffer systems. This is accomplished through emulating the presence of ... -
Unrestricted State Complexity Of Binary Operations On Regular And Ideal Languages
(Institut für Informatik, 2017-08-27)We study the state complexity of binary operations on regular languages over different alphabets. It is known that if L′m and Ln are languages of state complexities m and n, respectively, and restricted to the same alphabet, ... -
The Unspoken Rules of Engagement: Understanding the Impact of Social Norm Violations in Human-Robot Interactions
(University of Waterloo, 2023-08-18)As robots increasingly permeate diverse domains such as healthcare, education, service industries, and domestic environments, the significance of understanding and navigating human-robot interactions intensifies. This ... -
Unsteady Free Convection from Elliptic Tubes at Large Grashof Numbers
(University of Waterloo, 2008-09-11)This study solves the problem of unsteady free convection from an inclined heated tube both numerically and analytically. The tube is taken to have an elliptic cross-section having a constant heat flux applied to its ... -
Unsupervised Aspect Discovery from Online Consumer Reviews
(University of Waterloo, 2014-05-02)The success of on-line review websites has led to an overwhelming number of on-line consumer reviews. These reviews have become an important tool for consumers when making a decision to purchase a product. This growth has ... -
Unsupervised Multilingual Alignment using Wasserstein Barycenter
(University of Waterloo, 2020-01-23)We investigate the language alignment problem when there are multiple languages, and we are interested in finding translation between all pairs of languages. The problem of language alignment has long been an exciting topic ... -
Unsupervised Spectral Ranking For Anomaly Detection
(University of Waterloo, 2014-09-10)Anomaly detection is the problem of finding deviations from expected normal patterns. A wide variety of applications, such as fraud detection for credit cards and insurance, medical image monitoring, network intrusion ... -
Unsupervised Syntactic Structure Induction in Natural Language Processing
(University of Waterloo, 2021-09-07)This work addresses unsupervised chunking as a task for syntactic structure induction, which could help understand the linguistic structures of human languages especially, low-resource languages. In chunking, words of a ... -
Up2Date Research: A personalized recommendation application for researchers
(University of Waterloo, 2023-04-19)In our current age, the number of academic papers published each year is growing at an exponential rate. Staying current in one’s respective field can not only be overwhelming, but a struggle to achieve. To help reach their ... -
Update-Aware Information Extraction
(University of Waterloo, 2023-11-20)Information extraction programs (extractors) can be applied to documents to isolate structured versions of some content by creating tabular records corresponding to facts found in the documents. When extracted relations ... -
Updating the Vertex Separation of a Dynamically Changing Tree
(University of Waterloo, 2004)This thesis presents several algorithms that update the vertex separation of a tree after the tree is modified; the vertex separation of a graph measures the largest number of vertices to the left of and including a vertex ... -
Upper and Lower Bounds for Text Upper and Lower Bounds for Text Indexing Data Structures
(University of Waterloo, 2008-01-23)The main goal of this thesis is to investigate the complexity of a variety of problems related to text indexing and text searching. We present new data structures that can be used as building blocks for full-text indices ... -
Upper Bounds for the Number of Integral Points on Quadratic Curves and Surfaces
(University of Waterloo, 2010-04-27)We are interested in investigating the number of integral points on quadrics. First, we consider non-degenerate plane conic curves defined over Z. In particular we look at two types of conic sections: hyperbolas with ... -
Upward Octagonal Drawings of Ternary Trees
(University of Waterloo, 2016-09-08)We explore ways to embed a ternary tree in an integer coordinate grid such that the width of the drawing is minimized. We provide upper and lower bounds on the width requirement of planar, straight-line, upward, order-preserving ... -
The Usability and Learnability of Pen/Tablet Mode Inferencing
(University of Waterloo, 2012-09-14)The inferred mode protocol uses contextual reasoning and local mediators to eliminate the need to access specic modes to perform draw, select, move and delete operations in a sketch interface. This thesis describe an ...
