Planar Open Rectangle-of-Influence Drawings
(University of Waterloo, 2012-05-18)A straight line drawing of a graph is an open weak rectangle-of-influence (RI) drawing, if there is no vertex in the relative interior of the axis parallel rectangle induced by the end points of each edge. Despite recent ... -
Planning and Deployment of Wireless Sensor Networks
(SAGE Publications (UK and US): Creative Commons Attribution, 2014-01-08)Editorial introduction to special issue on Planning and Deployment of Wireless Sensor Networks published in the International Journal of Distributed Sensor Networks, 9(5). 2014. -
Plethysms of Chromatic and Tutte Symmetric Functions
(The Electronic Journal of Combinatorics, 2022)Plethysm is a fundamental operation in symmetric function theory, derived directly from its connection with representation theory. However, it does not admit a simple combinatorial interpretation, and finding coefficients ... -
PLOX: A Secure Serverless Framework for the Smart Home
(University of Waterloo, 2021-08-17)Smart hubs play a key role in the modern smart home in executing code on behalf of devices locally or on the cloud. Unfortunately, smart hubs are prone to security problems due to misconfigurations, device over permissioning ... -
POEM: Pattern-Oriented Explanations of CNN Models
(University of Waterloo, 2022-09-16)While Convolutional Neural Networks (CNN) achieve state-of-the-art predictive performance in applications such as computer vision, their predictions are difficult to explain, similar to other types of deep learning models. ... -
Poincare Waves and Kelvin Waves in a Circular Lake
(University of Waterloo, 2009-01-28)When wind blows over a stratified lake an interface tilt is often generated, and internal waves usually appear after the wind stops. Internal waves in lakes are studied in many literatures, but most assume a hydrostatic ... -
Point-to-Point Traffic in Wireless Mesh Networks
(University of Waterloo, 2010-07-29)Although most work on Wireless Mesh Networks (WMNs) has focused on traffic flowing in and out of the network via gateways, traffic within the WMN may also be significant in many environments. This point-to-point (P2P) ... -
Poissonian potential measures for Lévy risk models
(Elsevier, 2018-09-01)This paper studies the potential (or resolvent) measures of spectrally negative Lévy processes killed on exiting (bounded or unbounded) intervals, when the underlying process is observed at the arrival epochs of an independent ... -
Policy Explanation and Model Refinement in Decision-Theoretic Planning
(University of Waterloo, 2013-08-30)Decision-theoretic systems, such as Markov Decision Processes (MDPs), are used for sequential decision-making under uncertainty. MDPs provide a generic framework that can be applied in various domains to compute optimal ... -
Policy Extraction via Online Q-Value Distillation
(University of Waterloo, 2019-08-27)Recently, deep neural networks have been capable of solving complex control tasks in certain challenging environments. However, these deep learning policies continue to be hard to interpret, explain and verify which limits ... -
Policy Resistance Undermines Superspreader Vaccination Strategies For Influenza
(Public Library of Science, 2013-03-01)Theoretical models of infection spread on networks predict that targeting vaccination at individuals with a very large number of contacts (superspreaders) can reduce infection incidence by a significant margin. These models ... -
Polyhedral Diameters and Applications to Optimization
(University of Waterloo, 2022-09-01)The Simplex method is the most popular algorithm for solving linear programs (LPs). Geometrically, it moves from an initial vertex solution to an improving neighboring one, selected according to a pivot rule. Despite decades ... -
Polynomial bounds for chromatic number II: Excluding a star-forest
(Wiley, 2022-10)The Gyárfás–Sumner conjecture says that for every forest H, there is a function fH such that if G is H-free then x(G) ≤ fH(w(G)) (where x,w are the chromatic number and the clique number of G). Louis Esperet conjectured ... -
Polynomial bounds for chromatic number. III. Excluding a double star
(Wiley, 2022-10)A “double star” is a tree with two internal vertices. It is known that the Gyárfás-Sumner conjecture holds for double stars, that is, for every double star H, there is a function fH such that if G does not contain H as ... -
A Poroelastic Model of Transcapillary Flow
(University of Waterloo, 2010-05-21)Transcapillary exchange is the movement of fluid and molecules through the porous capillary wall, and is important in maintaining homeostasis of bodily tissues. The classical view of this process is that of Starling's ... -
Port-based teleportation of continuous quantum variables
(University of Waterloo, 2014-08-27)Quantum teleportation allows to transmit quantum information using classical information and entanglement only. Port-based teleportation is a variation of this procedure that involves simpler recovery operations to obtain ... -
Portfolio Selection Under Nonsmooth Convex Transaction Costs
(University of Waterloo, 2006)We consider a portfolio selection problem in the presence of transaction costs. Transaction costs on each asset are assumed to be a convex function of the amount sold or bought. This function can be nondifferentiable ... -
Posets of Non-Crossing Partitions of Type B and Applications
(University of Waterloo, 2007-10-19)The thesis is devoted to the study of certain combinatorial objects called \emph{non-crossing partitions}. The enumeration properties of the lattice ${\textsf{NC$^{\textsf{\,A}}$(n)}}\,$ of \emph{non-crossing partitions} ... -
The Positive and Negative Influence of Search Results on People's Decisions about the Efficacy of Medical Treatments
(ACM, 2017-10-01)People regularly use web search engines to investigate the efficacy of medical treatments. Search results can contain documents that present incorrect information that contradicts current established medical understanding ... -
Positive Gaming: Workshop on Gamification and Games for Wellbeing
(Association for Computing Machinery, 2017-10-15)Gamification and games have been used and studied in a variety of applications related with health and wellbeing. Nevertheless, there are very few studies aimed at designing games (whether serious games or recreational ...
