Post-Quantum Elliptic Curve Cryptography
(University of Waterloo, 2016-05-16)We propose and develop new schemes for post-quantum cryptography based on isogenies over elliptic curves. First we show that ordinary elliptic curves are have less than exponential security against quantum computers. These ... -
Post-Quantum Security of Authenticated Key Establishment Protocols
(University of Waterloo, 2016-04-20)We present a security model for authenticated key establishment that allows for quantum interactions between the adversary and quantum oracles that emulate classical parties, resulting in a truly post-quantum security ... -

(University of Waterloo, 2014-09-08)Postadolescence is a relatively new sociological and psychological phenomenon. While previous research has primarily read the postadolescent novel as an adolescent novel, this thesis seeks to contribute to existing scholarship ... -
Posthumanist Medicine: Participatory Healthcare, Medical Humanities, and Digital Media
(University of Waterloo, 2015-08-24)This dissertation explores the construction of illness in the context of two interrelated processes that both propose a more empowered patient role and a whole person model for healthcare. Specifically, these contexts are ... -
Postman Problems on Mixed Graphs
(University of Waterloo, 2003)The <i>mixed postman problem</i> consists of finding a minimum cost tour of a mixed graph <i>M</i> = (<i>V</i>,<i>E</i>,<i>A</i>) traversing all its edges and arcs at least once. We prove that two well-known linear ... -
Postural Effects on Brain Blood Flow and Cognition in Heart Failure
(University of Waterloo, 2014-02-06)With the aging population on the rise, the prevalence of heart failure is expected to increase in the coming years. Heart failure is independently correlated with cognitive decline and has a negative impact on quality of ... -
Postural motor learning and the effects of age on practice-related improvements in compensatory posture control
(University of Waterloo, 2009-08-27)The purpose of this thesis was to examine the capacity for acquisition and retention of practice-related improvements in compensatory posture control and the nature of postural motor learning among healthy young and older ... -
Postural state modulation of cortical balance reactions
(University of Waterloo, 2019-09-25)Safe and effective walking is a crucial part of daily human life, but the number of injuries and resulting financial burden from falls during walking is increasing. As a result, it continues to be important to advance ... -
Posture Dependent Vibration Resistance of Serial Robot Manipulators to Applied Oscillating Loads
(University of Waterloo, 2010-01-11)There are several advantages to replacing CNC machinery with robotic machine tools and as such robotic machining is emerging into the manufacturing and metal cutting industry. There remain several disadvantages to using ... -
Posturing Horses: Xenophon on Biomechanical Soundness in The Art of Horsemanship
(University of Waterloo, 2022-08-12)As early as the Bronze Age, ancient Greek horses shared in the social status of the military elite. The ritual inclusion of horses and their equipment in burial practices from the Bronze Age to the Classical period marked ... -
Potential and Limitations of MCM-41 in Dechlorination Reactions
(University of Waterloo, 2007-04-27)The purpose of this thesis was to conduct preliminary research into the feasibility of using MCM-41 as a catalyst support material in the treatment of organochloride contaminated water. Specifically, the stability of MCM-41 ... -
Potential and Observed Release of Phosphorus from Crop Residue and Cover Crops Over the Non-growing Season in a Cool Temperate Region
(University of Waterloo, 2016-10-11)Maintaining crop residue or cover crops on fields during winter is a recommended Best Management Practice (BMP) in temperate regions. However, losses of phosphorus (P) to runoff have been attributed to vegetation following ... -
Potential Applications of Silk Fibroin as a Biomaterial
(University of Waterloo, 2013-06-19)Fibroin is a biopolymer obtained from the cocoons of the Bombyx mori silkworm that offers many unique advantages. In this thesis work, fibroin was processed into a regenerated film and examined for potential biomaterial ... -
