In a bilateral teleoperation system, conditions involving open-loop model parameters and controller parameters for ensuring teleoperator passivity are useful as control design guidelines to attain maximum teleoperation transparency (due to passivity/transparency tradeoffs). By teleoperator, we...

An Electrochemical Impedance Spectroscopic Diagnostic Device for Characterization of Liquid-Liquid Systems and Phase Separation Detection in Emulsions
DownloadFall 2013
Rapid characterization of complex fluids, especially sensing emulsion stability, is crucial for many industrial applications, ranging from pharmaceutical industry to petroleum production. Electrochemical impedance spectroscopy (EIS) is a powerful tool for electrical characterization of such...

An Item Analysis of the Instability of Parent Report Scores on the Pediatric Evaluation of Disability Inventory
DownloadFall 2012
Purpose: To evaluate item instability of the Pediatric Evaluation of Disability Inventory – Functional Skills Scale completed by parents. Methods: Scoring instability was analyzed between baseline and after 6 months of intervention (T1-T2) on 113 children and between end of intervention and 3...

Atomistic Simulations for Investigating Structural Stability and Selecting Initial Adsorption Orientation of Lysozyme and Apo-α-Lactalbumin at Hydrophobic and Hydrophilic Surfaces
DownloadFall 2012
Molecular dynamics (MD) simulations were performed to investigate the structural stability of lysozyme and apo-α-lactalbumin under physiological pH and solution. Upon introduction to the solution, apo-α-lactalbumin showed lower stability than lysozyme with higher backbone root mean square...

During the extraction of crude oil or bitumen, stable water-in-oil emulsions are inevitably formed. The emulsified water contains chloride ions and other organic acidic compounds that cause severe corrosion problems to the downstream plant equipment, creating operational and safety issues and...

Characterization of magnetic nanoparticles as contrast agents and their application for quantitative magnetic susceptibility monitoring of the waterflooding of heavy oil in real time
DownloadSpring 2018
Waterflooding is one enhanced oil recovery process used in heavy oil reservoirs such as at Cold Lake in North-Eastern Alberta. However, little has been published in terms of imaging heavy oil waterfloods, mainly due to the similar densities of water and heavy oil, which makes it difficult to...

Clinical Utility of Proposed Gait Stability Measures: Selection, Application and Evaluation of the Extrapolated Centre of Mass
DownloadSpring 2019
Gait stability is the ability to maintain a state of equilibrium during locomotion. In humans, this includes the need to maintain a stable walking pattern while regularly positioning the body in a state of imbalance. Thus, it is not surprising that gait is accompanied by an increased risk of...

Fall 2014
The formation of stable water-in-oil emulsions during bitumen extraction poses problems for water separation from diluted bitumen, which leads to equipment corrosion and catalyst fouling in downstream operations. Demulsifiers are used to break the stable emulsions and assist the separation of...

Detecting minimum energy states and multi-stability in nonlocal advection–diffusion models for interacting species

Valeria Giunta, Thomas Hillen, Mark A. Lewis, Jonathan R. Potts
Deriving emergent patterns from models of biological processes is a core concern of mathematical biology. In the context of partial differential equations, these emergent patterns sometimes appear as local minimisers of a corresponding energy functional. Here we give methods for determining the...
