Personality Traits of GitHub Maintainers and Their Effects on Project Success
(University of Waterloo, 2020-08-28)Online collaborative environments have become important virtual workplaces for developers to work on a common problem. GitHub is an example of such environment that hosts a wealth of open source software projects. Questions ... -
Personalizing Persuasive Strategies in Gameful Systems to Gamification User Types
(Association for Computing Machinery, 2018-04-21)Persuasive gameful systems are effective tools for motivating behaviour change. Research has shown that tailoring these systems to individuals can increase their efficacy; however, there is little knowledge on how to ... -
Perspective in Two Dimensions for Computer Graphics
(University of Waterloo, 2013-01-28)Computer graphics perspective is based on photography, the pin-hole camera model. This thesis examines the perspective as practiced by artists, who develop the picture geometry within the planar surface of the canvas. Their ... -
Perspectives on software-defined networks: interviews with five leading scientists from the networking community
(SpringerOpen, 2015-10-30)Software defined Networks (SDNs) have drawn much attention both from academia and industry over the last few years. Despite the fact that underlying ideas already exist through areas such as P2P applications and active ... -
A Phase Model with Large Time Delayed Coupling
(Elsevier, 2020-10)We consider two identical oscillators with weak, time delayed coupling. We start with a general system of delay differential equations then reduce it to a phase model. With the assumption of large time delay, the resulting ... -
Phase models and clustering in networks of oscillators with delayed coupling
(Elsevier, 2017-09-19)We consider a general model for a network of oscillators with time delayed coupling where the coupling matrix is circulant. We use the theory of weakly coupled oscillators to reduce the system of delay differential equations ... -
Physical Design for Non-relational Data Systems
(University of Waterloo, 2018-08-09)Decades of research have gone into the optimization of physical designs, query execution, and related tools for relational databases. These techniques and tools make it possible for non-expert users to make effective use ... -
Physical Modelling and the Associated Acoustic Behaviour of Trumpets and Trombones
(University of Waterloo, 2019-09-30)Accurately modelling the production of realistic musical notes in brass instruments is no easy task. Compared to woodwind instruments, brass instruments are considerably longer and constructed with bends, valves or coils, ... -
Physically-based Simulation of Tornadoes
(University of Waterloo, 2005)In this physically-based tornado simulation, the tornado-scale approach techniques are applied to simulate the tornado formation environment. The three-dimensional Navier-Stokes equations for incompressible viscous ... -
Pick Interpolation and the Distance Formula
(University of Waterloo, 2012-05-09)The classical interpolation theorem for the open complex unit disk, due to Nevanlinna and Pick in the early 20th century, gives an elegant criterion for the solvability of the problem as an eigenvalue problem. In the 1960s, ... -
PID Control of Systems with Hysteresis
(University of Waterloo, 2009-04-29)Hysteresis is exhibited by many physical systems. Smart materials such as piezoelectrics, magnetostrictives and shape memory alloys possess useful properties, especially in the field of micropositioning, but the control ... -
Piercing axis-parallel boxes
(The Electronic Journal of Combinatorics, 2018)Let F be a finite family of axis-parallel boxes in Rd such that F contains no k + 1 pairwise disjoint boxes. We prove that if F contains a subfamily M of k pairwise disjoint boxes with the property that for every F E F ... -
Pixelating Vector Art
(University of Waterloo, 2014-01-09)Pixel art is a popular style of digital art often found in video games. It is typically characterized by its low resolution and use of limited colour palettes. Pixel art is created manually with little automation because ... -
Planar graphs without 3-cycles and with 4-cycles far apart are 3-choosable
(University of Waterloo, 2016-09-16)A graph G is said to be L-colourable if for a given list assignment L = {L(v)|v ∈ V (G)} there is a proper colouring c of G such that c(v) ∈ L(v) for all v in V (G). If G is L-colourable for all L with |L(v)| ≥ k for all ... -
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 ...
