Motion Processing of Reverse Phi
(University of Waterloo, 2019-11-18)Introduction: When the contrast of the successive images is reversed for a target in an apparent motion stimulus, the perceived direction is reversed, i.e., opposite of phi motion, which is an integration of the sequential ... -
Effects of column imperfections on capacity of steel frames in variable loading
(Journal of Constructional Steel Research, 2019-11-15)The presence of column initial imperfections in a steel frame can increase deflections and decrease its load carrying capacity. A method is proposed for evaluating the lateral stiffness, inter-storey displacement and ... -
Segregation of chain ends to the surface of a polymer melt: effect of surface profile versus chain discreteness
(Springer, 2016)Silberberg has argued that the surface of a polymer melt behaves like a reflecting boundary on the random-walk statistics of the polymers. Although this is approximately true, independent studies have shown that violations ... -
Entropic segregation of short polymers to the surface of a polydisperse melt
(Springer, 2017)Chain ends are known to have an entropic preference for the surface of a polymer melt, which in turn is expected to cause the short chains of a polydisperse melt to segregate to the surface. Here, we examine this entropic ... -
Shear deformation effects on stability of unbraced steel frames in variable loading
(Journal of Constructional Steel Research, 2019-11-11)The generalized lateral stiffness equation of a semi-rigidly connected frame with accounting for shear deformation is derived in this paper. The lateral stiffness equation can be used to determine the critical loads of ... -
Compressible Matrix Algebras and the Distance from Projections to Nilpotents
(University of Waterloo, 2019-11-15)In this thesis we address two problems from the fields of operator algebras and operator theory. In our first problem, we seek to obtain a description of the unital subalgebras $\mathcal{A}$ of $\mathbb{M}_n(\mathbb{C})$ ... -
On Occupancy Based Randomized Load Balancing for Large Systems with General Distributions
(University of Waterloo, 2019-11-13)Multi-server architectures are ubiquitous in today's information infrastructure whether for supporting cloud services, web servers, or for distributed storage. The performance of multi-server systems is highly dependent ... -
The Influence of Social Networks on Mental and Emotional Health Resource-Seeking Behaviours Amongst Women who are Refugees from Syria
(University of Waterloo, 2019-11-12)Background and Objectives: While the arrival of migrants into Canada from foreign countries is not a new phenomenon, recent years have seen a larger than usual influx of individuals come into the nation. Between 2015 and ... -
Environmental Engagement and Generation Z: Evaluating and Modifying the YEEP Framework Against Research and Observations on Generation Z Youth and Youth Leaders
(University of Waterloo, 2019-11-11)In October 2018, the United Nations Intergovernmental Panel on Climate Change (IPCC) announced that the global community has 12 years to stop the rapid growth of climate change and avoid increased threats of drought, ... -
Open Aerial Map, Drones and Archaeology: The implications of using drones to contribute and share aerial data on an open data repository
(University of Waterloo, 2019-11-04)The purpose of this research is to determine the potential benefits and challenges of volunteered aerial imagery by looking at OpenAerialMap (OAM) and by presenting how a repository like OAM may be applied in archaeological ... -
Future projections of rain-on-snow events and their spatiotemporal distribution across the Fraser River Basin, British Columbia, Canada
(University of Waterloo, 2019-11-01)This study analyzes the projected changes of rain-on-snow (ROS) event characteristics (frequency, mechanism and runoff) for the future (2020 – 2099) period with respect to the historical period (1970 – 1999) over the Fraser ... -
Contemporary Forest Harvesting Impacts on Drinking Water Quality and Treatability
(University of Waterloo, 2019-10-31)Forested watersheds supply ~75% of global accessible freshwater resources and serve as important sources of drinking water. Both natural and anthropogenic landscape disturbances in these regions can deteriorate water quality ... -
Scalable Surfaces for Electromagnetic Energy Harvesting and Wireless Power Transfer
(University of Waterloo, 2019-10-31)The idea of collecting electromagnetic (EM) energy and converting it into various forms of useful power dates back to the early 20th century. Nikola Tesla's wireless power transfer experiments demonstrated the concept ... -
THE UNCERTAINTY THAT SHAPES THE OPERATIONS OF HEALTH-FOCUSED NON-GOVERNMENT ORGANIZATIONS IN VIETNAM
(University of Waterloo, 2019-10-31)Objective: This research project explores how uncertainty shapes NGOs operating in the health sector in relation to other institutions, and how NGOs strategize to maintain their image and survive under uncertain conditions, ... -
Understanding the Pathways in the Relationship between Engagement with Nature and Wellbeing
(University of Waterloo, 2019-10-31)It is now well established that contact with nature, regardless of activity type or experience, can have positive influences on the physical, psychological, social, and spiritual health and wellbeing of individuals. The ... -
A GIS- Based Material Stock-Flow Analysis of Antigua & Barbuda through the lens of the built and socio-economic environment
(University of Waterloo, 2019-10-31)Small island developing states (SIDS) in the Caribbean are centered around a service-based economy, where the built environment (or material stocks) functions as the backbone of their social and economic wellbeing. The ... -
Finding the Ideal Nesting Place: Chinese Encounters with Indigenous and Euro-Canadian Peoples in British Columbia, 1858-1947
(University of Waterloo, 2019-10-31)Since the conclusion of the First Opium War (1842) when the ports of China were forced open by the British, adventurous Chinese emigrants traded their dismal prospects at home for British Columbia—a foreign land of ... -
Evaporation of Liquid Wall Film in Direct Injection Spark Ignition Engine-like Conditions
(University of Waterloo, 2019-10-30)The liquid wall film formed by the spray impingement in Direct Injection Spark Ignition (DISI) engines can directly produce a large amount of Particle Matter (PM) emissions. The PM emissions can be tremendously reduced if ... -
Field-Sweep Control in Magnetic Resonance and k-space Analysis
(University of Waterloo, 2019-10-30)In a general magnetic resonance experiment, resonant radiofrequency or microwave fields are applied to an ensemble of electron or nuclear spins to determine their magnetic interactions with their local environment. These ... -
Deep, effortless concentration: re-examining the flow concept and exploring relations with inattention, absorption, and personality
(Springer, 2018-06-18)Conceptualizing the construct of flow in terms of ‘deep and effortless concentration’, we developed two measurement scales designed to index individual differences in flow during ‘internal’ tasks, such as thinking (deep ...
