Preparing and Tuning the Reactivity of Palladium Carbenes and an Unusual Catalytic Isomerization of Diphenylcyclopropanes
(University of Waterloo, 2007-09-26)The preparation of palladium carbene intermediates from diphenylketene is proposed. Experiments to trap these intermediates with alkenes have been conducted and optimized, with cyclopropanes being prepared in up to 69% ... -
Preparing Catalogers for RDA Training
(Taylor & Francis, 2009-09)This article prepares catalogers for the new cataloging standard Resource Description and Access (RDA) by giving trainers and Library and Information Science (LIS) educators the information they need to plan training for ... -
Preparing for the Eschaton: A Theology of Work
(University of Waterloo, 2010-10-27)Work occupies a significant part of our lives, and yet it is often not given sufficient attention. Certainly there is much consideration given to finding a career, and succeeding in work, but not enough to how our work ... -
Preparing Nanotubes via Polymerization of Diacetylene Functionality Containing Carbon-based Macrocycles
(University of Waterloo, 2013-09-05)Nanofibers and nanotubes have been extensively studied in materials science due to their extraordinary thermal conductivity, excellent mechanical and electrical properties, and their potential capability for gas storage. ... -
Prepositional Phrase Attachment Disambiguation Using WordNet
(University of Waterloo, 2006)In this thesis we use a knowledge-based approach to disambiguating prepositional phrase attachments in English sentences. This method was first introduced by S. M. Harabagiu. The Penn Treebank corpus is used as ... -
Preprocessing and Reduction for Semidefinite Programming via Facial Reduction: Theory and Practice
(University of Waterloo, 2013-11-26)Semidefinite programming is a powerful modeling tool for a wide range of optimization and feasibility problems. Its prevalent use in practice relies on the fact that a (nearly) optimal solution of a semidefinite program ... -

Preschoolers’ reasoning about the “how”, “what” and “when” of ownership.
(University of Waterloo, 2016-03-30)My dissertation includes three papers. Paper one investigates preschoolers’ appreciation of how people become owners. In two experiments, 70 3-to-5-year-olds were asked to explain why a character owns, likes, or uses certain ... -
Prescriptive Semantics For Big-Step Modelling Languages
(University of Waterloo, 2011-02-22)With the popularity of model-driven methodologies and the abundance of modelling languages, a major question for a modeller is: Which language is suitable for modelling a system under study? To answer this question, one ... -
A Present Absence
(University of Waterloo, 2017-06-14)For the last ten years I have travelled with my camera out on the roads of the Canadian prairies, usually for a few days at a time, up and down stretches of highways, grids, and back roads, stopping to investigate whatever ... -
Preservation and Development at the Great Wall World Heritage Sites, China
(University of Waterloo, 2010-01-22)Heritage preservation and tourism development are inevitably intertwined at heritage sites. The relationships between tourism use and the preservation of heritage resources are characterized by both symbioses and tension ... -
The Preservation and Stewardship of Archaeological Sites in the Boreal Forest: A Public Issues Approach
(University of Waterloo, 2014-01-23)Archaeological sites in the boreal forest are facing threats due to urban development, resource exploitation, vandalism, and infrastructure development, among others. In the context of archaeological site preservation as ... -
A Preservationist Approach to Relevant Logic
(University of Waterloo, 2014-08-29)The semantics I develop extend an approach to logic called preservationism. The preservationist approach to logic interprets non-classical consequence relations as preserving something other than truth. I specifically ... -

(University of Waterloo, 2010-12-16)Archaeological sites around the world are facing many challenges. These challenges include urban expansion, resource exploitation, tourism, governmental infrastructure programs such as road development and one of the ... -
Preserving Geometry and Topology for Fluid Flows with Thin Obstacles and Narrow Gaps
(Association for Computing Machinery, 2016-07-01)Fluid animation methods based on Eulerian grids have long struggled to resolve flows involving narrow gaps and thin solid features. Past approaches have artificially inflated or voxelized boundaries, although this sacrifices ... -
Preserving Measured Structure During Generation and Reduction of Multivariate Point Configurations
(University of Waterloo, 2018-05-30)Inherent in any multivariate data is structure, which describes the general shape and distribution of the underlying point configuration. While there are potentially many types of structure that could be of interest, ... -
