Optimization and control of a thin film growth process: A hybrid first principles/artificial neural network based multiscale modelling approach
(Elsevier, 2018-11-02)This work details the construction and evaluation of a low computational cost hybrid multiscale thin film deposition model that couples artificial neural networks (ANNs) with a mechanistic (first-principles) multiscale ... -
Optimization of lipid production in Chlorella vulgaris for biodiesel production using flux balance analysis
(Elsevier, 2019-01-15)Microalgae, the world’s largest group of photosynthetic organisms, convert atmospheric CO2 to polar and neutral lipids using sunlight, which after esterification can be utilized for biodiesel production. In the present ... -
Optimization of muscle activation schemes in a finite element neck model simulating volunteer frontal impact scenarios
(Elsevier, 2020-03-07)Neck muscle activation is increasingly important for accurate prediction of occupant response in automotive impact scenarios and occupant excursion resulting from active safety systems such as autonomous emergency braking. ... -
Optimization of the hydrodynamic characteristics of a karst conduit with CFPv2 coupled to OSTRICH
(Elsevier, 2018-12-01)In order to better define the characteristics of a karst conduit, an integrated hydrogeological study including numerical modeling using CFPv2 is conducted at a karst aquifer in the Zagros Mountain Region of Iran. The ... -
Optimizing hydrological consistency by incorporating hydrological signatures into model calibration objectives
(American Geophysical Union, 2015-05-31)The simulated outcome of a calibrated hydrologic model should be hydrologically consistent with the measured response data. Hydrologic modelers typically calibrate models to optimize residual-based goodness-of-fit measures, ... -
‘Optimulation’ in Chemical Reaction Engineering: The Oxidative Coupling of Methane as a Case Study
(ACS, 2018-06-07)The optimization of reacting systems, including chemical, biological, and macromolecular reactions, is of great importance from both theoretical and practical standpoints. Even though several classical deterministic and ... -
An Optokinetic Nystagmus Detection Method for Use With Young Children
(Institute of Electrical and Electronics Engineers, 2015-03-05)The detection of vision problems in early childhood can prevent neurodevelopmental disorders such as amblyopia. However, accurate clinical assessment of visual function in young children is challenging. optokinetic nystagmus ... -
ORCID education: a departmental approach
(Emerald, 2021-03-22)Purpose This paper aims to provide a case study of an ORCID promotion at the University of Waterloo School of Optometry and Vision Science, providing context for the importance of education in ORCID outreach. Design/ ... -
Ordering and Reverse Ordering Mechanisms of Triblock Copolymers in the Presence of Solvent
(MDPI, 2009-02-27)Self-consistent field theory is used to study the self-assembly of a triblock copolymer melt. Two different external factors (temperature and solvent) are shown to affect the self-assembly. Either one or two-step self-assembly ... -
Ordering mechanisms in triblock copolymers
(American Physical Society, 2004)The ordering mechanisms for an ABC triblock copolymer system are studied using self-consistent field theory. We find a two-phase mechanism, similar to what has been suggested experimentally two-step mecha- nism. Analysis ... -
ORGANISATIONAL CHANGE IN THE INNOVATING FIRM: SIZE, R&D AND SECTOR EFFECTS
(World Scientific, 2019-08-05)This study investigates whether organisational innovation has positive impacts on small and medium enterprises, using three waves of the South Korean innovation survey. While correcting for endogeneity, we find that the ... -
Origin of change in molecular-weight dependence for polymer surface tension
(APS publishing, 2008-09-30)Self-consistent-field theory is used to reproduce the behavior of polymer surface tension with molecular-weight for both lower and higher molecular-weight polymers. The change in behavior of the surface tension between ... -
Origins of Elastic Properties in Ordered Block Copolymer/Nanoparticle Composites
(American Chemical Society, 2004)We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock copolymer system. This weakening is due ... -
Origins of the failure of classical nucleation theory for nanocellular polymer foams
(RSC publishing, 2011-07-06)Relative nucleation rates for fluid bubbles of nanometre dimensions in polymer matrices are calculated using both classical nucleation theory and self-consistent field theory. An identical model is used for both calculations ... -
Orthogonal Adsorption Onto Nano-Graphene Oxide Using Different Intermolecular Forces for Multiplexed Delivery
(Wiley, 2013-05-31)Nano-graphene oxide can adsorb both doxorubicin and zwitterionic dioleoyl-sn-glycero-3-phosphocholine (DOPC) liposomes in an orthogonal and non-competing manner with high capacities based on different surface and intermolecular ... -
The other side of the screen: The impact of perspective-taking on adolescents’ online communication
(Elsevier, 2021-10)Introduction: In recent decades, adolescents’ interactions with peers have increasingly transitioned online. While socially interactive technologies provide multiple avenues for positive communication between peers, ... -
Our adventures make me feel secure: Novel activities boost relationship satisfaction through felt security
(Elsevier, 2020-07)Past research has established the relational benefits of engaging in novel tasks with a romantic partner. However, little empirical evidence exists for the mechanisms responsible. The current research examined growth ... -
Outlook On A Worldwide Forest Transition
(Public Library of Science, 2013-10-09)It is not clear whether a worldwide "forest transition" to net reforestation will ever occur, and the need to address the main driver-agriculture-is compelling. We present a mathematical model of land use dynamics based ... -
Overconfidently Underthinking: Narcissism negatively predicts Cognitive Reflection
(Taylor & Francis, 2020)There exists a large body of work examining individual differences in the propensity to engage in reflective thinking processes. However, there is a distinct lack of empirical research examining the role of dispositional ... -
