• #### A PAC-Theory of Clustering with Advice ﻿

(University of Waterloo, 2018-05-17)
In the absence of domain knowledge, clustering is usually an under-specified task. For any clustering application, one can choose among a variety of different clustering algorithms, along with different preprocessing ...
• #### Packaging and Characterization of a NbTiN Superconducting Nanowire for the Design of an Optimal Nanowire Meander Structure ﻿

(University of Waterloo, 2013-04-23)
The Superconducting Nanowire single-photon detector (SNSPD) made with niobium-titanium nitride (NbTiN) thin films fabricated on oxidized silicon substrates are highly promising nanodevices. The SNSPD is an immensely capable ...
• #### Packaging and Characterization of NbN Superconducting Nanowire Single Photon Detectors ﻿

(University of Waterloo, 2009-05-22)
Superconducting nanowire single-photon detectors (SNSPDs) are nanodevices usually made from thin niobium nitride (NbN) films. Operated at liquid helium temperature, they can exhibit high detection efficiency with low ...
• #### Packing and Covering Odd (u,v)-trails in a Graph ﻿

(University of Waterloo, 2016-09-27)
In this thesis, we investigate the problem of packing and covering odd $(u,v)$-trails in a graph. A $(u,v)$-trail is a $(u,v)$-walk that is allowed to have repeated vertices but no repeated edges. We call a trail \emph{odd} ...
• #### Packing Directed Joins ﻿

(University of Waterloo, 2004)
Edmonds and Giles conjectured that the maximum number of directed joins in a packing is equal to the minimum weight of a directed cut, for any weighted directed graph. This is a generalization of Woodall's Conjecture ...
• #### Packing Unit Disks ﻿

(University of Waterloo, 2008-08-27)
Given a set of unit disks in the plane with union area A, what fraction of A can be covered by selecting a pairwise disjoint subset of the disks? Richard Rado conjectured 1/4 and proved 1/4.41. In this thesis, we consider ...
• #### Packing: An Architect's Guide ﻿

(University of Waterloo, 2011-08-19)
A study of packing constructs a critique of the everyday: a dialogue between chaos and order, surface and area, interior and exterior, gravity and lightness. In search of tangible expression of the spatial processes I ...
• #### Pain Management within the Long-term Care Setting: An Inquiry into Staff-perceived Contemporary Pain Management Practices ﻿

(University of Waterloo, 2014-05-06)
Background: Chronic pain is a frequent and undertreated ailment within the long-term care community (Herman et al, 2009). The likelihood of experiencing pain increases with age and failure to treat this condition may ...
• #### Pairing Generation for Airline Crew Scheduling ﻿

(University of Waterloo, 2012-08-30)
Airline planning is a complex and difficult process. The biggest airlines in the world plan for and operate fleets of over 700 aircraft using tens of thousands of crew members. As such, small percentages in savings translate ...
• #### Pairs Trading Based on Costationarity ﻿

(University of Waterloo, 2015-09-25)
Arbitrage is a widely sought after phenomenon in financial markets: profit without any risk is very desirable. Statistical arbitrage is a related concept: the idea is to take advantage of market inefficiencies using ...
• #### Paleoevolution of Pore Fluids in Glaciated Geologic Settings ﻿

(University of Waterloo, 2009-06-17)
Nuclear power generation is being regarded as a solution to ever increasing demand for electricity, and concerns over global warming and climate change due to the use of fossil fuels. Although nuclear power generation is ...
• #### Paleoglaciological dynamics in northern Manitoba and the subglacial bed mosaic ﻿

(University of Waterloo, 2013-06-24)
During the last glacial maximum (LGM), some 20 ka ago, northern Manitoba was situated beneath 3 to 4.5 km of ice, on the outer fringe of a major ice spreading center of the Laurentide Ice Sheet. The region has also been ...
• #### Paleolimnological evidence of the effects of recent cultural eutrophication and climatic variability during the last 300 years in Lake Malawi, East Africa ﻿

(University of Waterloo, 2005)
Lake Malawi is the second largest lake in Africa, supporting diverse populations of endemic cichlids and supplying essential water resources to Malawi, Mozambique and Tanzania. However, population growth, rapid deforestation ...
• #### Paleozoic transpressional tectonics in the Beishan orogenic collage, Northwest China: Evolution of the Hongliuhe suture zone ﻿

(University of Waterloo, 2016-01-21)
The Beishan orogenic collage is a southern, central subset of the Central Asian Orogenic Belt, in Northwest China. It is an accretionary orogen that was active during the early Paleozoic, transitioning to convergent ...
• #### Palmprint Identification Based on Generalization of IrisCode ﻿

(University of Waterloo, 2007-01-24)
The development of accurate and reliable security systems is a matter of wide interest, and in this context biometrics is seen as a highly effective automatic mechanism for personal identification. Among biometric technologies, ...
• #### Panic Detection in Human Crowds using Sparse Coding ﻿

(University of Waterloo, 2012-08-29)
Recently, the surveillance of human activities has drawn a lot of attention from the research community and the camera based surveillance is being tried with the aid of computers. Cameras are being used extensively for ...
• #### Paradigm Shift: Does River Metabolism Mask the Isotopic Signal of Nitrate Sources? ﻿

(University of Waterloo, 2017-05-19)
Nitrate (NO₃⁻) is the most ubiquitous contaminant in surface and groundwaters in Canada. Synthetic fertilizer application and manure production in intensive agricultural areas contribute large quantities of NO₃⁻ to the ...
• #### Paralinguistic and Nonverbal Behaviour in Social Interactions: A Lens Model Perspective ﻿

(University of Waterloo, 2010-12-20)
It is widely accepted in our society that people’s paralinguistic (i.e., non-semantic characteristics of the voice) and nonverbal (i.e., posture, gestures, and facial expressions) behaviours play an important role in ...
• #### Parallel Multiplier Designs for the Galois/Counter Mode of Operation ﻿

(University of Waterloo, 2008-06-09)
The Galois/Counter Mode of Operation (GCM), recently standardized by NIST, simultaneously authenticates and encrypts data at speeds not previously possible for both software and hardware implementations. In GCM, data ...
• #### Parallel Pattern Search in Large, Partial-Order Data Sets on Multi-core Systems ﻿

(University of Waterloo, 2011-01-20)
Monitoring and debugging distributed systems is inherently a difficult problem. Events collected during the execution of distributed systems can enable developers to diagnose and fix faults. Process-time diagrams are ...
