Calibrating the Long-Range Backbone Dynamics of Polymers in Solution Using Two Different Models
(University of Waterloo, 2022-09-29)The fluorescence decays of a series of 41 pyrene-labeled poly(oligo(ethylene glycol)methyl ether methacrylate)s (Py-PEGnMA where n = 0, 1, 2, 3, 4, 5, 9, 16, 19) were prepared by free-radical polymerization of 1-pyrenebutyl ... -
Carrot Or Stick? Modelling How Landowner Behavioural Responses Can Cause Incentive-Based Forest Governance To Backfire
(Public Library of Science, 2013-10-30)Mitigating the negative impacts of declining worldwide forest cover remains a significant socio-ecological challenge, due to the dominant role of human decision-making. Here we use a Markov chain model of land-use dynamics ... -
Characterization of the Distribution of Pyrene Molecules in Confined Geometries with the Model Free Analysis
(American Chemical Society, 2017-12-21)Evidence is provided showing that global Model Free Analysis (MFA) of monomer and excimer fluorescence decays of pyrene dissolved in aqueous solutions of sodium dodecyl sulfate (SDS) provides the same structural and dynamic ... -
Design, Modeling, and Nonlinear Dynamics of a Cantilever Beam-Rigid Body Microgyroscope
(University of Waterloo, 2013-12-06)A new type of cantilever beam gyroscope is introduced, modeled, and analyzed. The main structure includes a cantilever beam and a rigid body attached to the free end of the beam. The model accounts for the eccentricity, ... -
Dynamics of a Three_Wheel Vehicle with Tadpole Design
(University of Waterloo, 2015-01-15)This study investigates the effect of applying camber angle on the handling, lateral stability, and ride comfort of a three-wheeled vehicle, which has two wheels in the front and one in the back, known as a tadpole design. ... -
Evaluating Vadose Zone Moisture Dynamics using Ground-Penetrating Radar
(University of Waterloo, 2012-02-27)Near-surface sediments in the vadose zone play a fundamental role in the hydrologic system. The shallow vadose zone can act as a buffer to delay or attenuate surface contaminants before they reach the water table. It also ... -
Hybrid Virtual Holonomic Constraints for a 2-D.O.F. Bipedal Robot
(IEEE, 2015-06-25)We apply virtual holonomic constraints (VHCs) to a fully actuated Euler-Lagrange system with impacts : a bipedal walking robot consisting of a stance leg, swing leg and hip mass. We call these hybrid virtual holonomic ... -
Long Range Polymer Chain Dynamics Probed with Pyrene Excimer Fluorescence
(University of Waterloo, 2016-09-27)A series of fluorescently labeled vinyl polymers bearing a C1-C18 side-chain (namely poly(methyl methacrylate), poly(butyl methacrylate), poly(octyl methacrylate), poly(lauryl methacrylate), and poly(stearyl methacrylate) ... -
Modelling and Control of Small-Scale Helicopter on a Test Platform
(University of Waterloo, 2008-05-23)The helicopter is a Multiple-Input Multiple-Output (MIMO) system with highly coupled characteristics, which increases the complexity of the system dynamics. In addition, the system dynamics of the helicopter are ... -
Modelling Interactions Between Forest Pest Invasions And Human Decisions Regarding Firewood Transport Restrictions
(Public Library of Science, 2014-04-15)The invasion of nonnative, wood-boring insects such as the Asian longhorned beetle (A. glabripennis) and the emerald ash borer (A. planipennis) is a serious ecological and economic threat to Canadian deciduous and mixed-wood ... -
Multimaterial Mesh-Based Surface Tracking
(Association for Computing Machinery, 2014-07-01)We present a triangle mesh-based technique for tracking the evolution of three-dimensional multimaterial interfaces undergoing complex deformations. It is the first non-manifold triangle mesh tracking method to simultaneously ... -
Policy Resistance Undermines Superspreader Vaccination Strategies For Influenza
(Public Library of Science, 2013-03-01)Theoretical models of infection spread on networks predict that targeting vaccination at individuals with a very large number of contacts (superspreaders) can reduce infection incidence by a significant margin. These models ... -
Satellite Dynamics in Dark Matter Halos
(University of Waterloo, 2010-09-01)I have used an analytic model of tidal interactions to predict the evolution of a substructure in a static dark matter halo. Given the initial conditions of the satellite and background halo, the model predicts with high ... -
Sexual Behavior, Risk Perception, And Hiv Transmission Can Respond To Hiv Antiviral Drugs And Vaccines Through Multiple Pathways
(Nature Publishing Group, 2015-10-28)There has been growing use of highly active antiretroviral treatment (HAART) for HIV and significant progress in developing prophylactic HIV vaccines. The simplest theories of counterproductive behavioral responses to such ... -
Using Pyrene Excimer Fluorescence To Probe the Interactions between Viscosity Index Improvers and Waxes Present in Automotive Oil
(American Chemical Society, 2017-03-28)A new methodology based on pyrene excimer fluorescence (PEF) was applied to quantitatively measure the actual level of intermolecular association between ethylene propylene (EP) copolymers in toluene in the presence of ...
