Effect of Ligation Method on Maxillary Arch Force / Moment Systems for a Simulated Lingual Incisor Malalignment
Download2014
Romanyk, Dan L., Major, Paul W., Seru, Surbhi, Toogood, Roger W., Carey, Jason P.
Introduction: The objectives of this study were to determine whether there is a difference in the magnitude of forces and moments produced by elastic ligation when compared to passive ligation, and whether these forces and moments propagate differently along the arch for the two ligation types. A...

Stochastic reconstruction using multiple correlation functions with different-phase-neighbor-based pixel selection
Download2014-01-01
Pant, L. M., Mitra, S. K., Secanell, Marc
A reconstruction methodology based on threshold energy based energy minimization (TA) and different-phase-neighbor (DPN)-based pixel swapping is presented. The TA method uses an energy threshold rather than probabilities as an acceptance criteria for annealing steps. The DPN-based pixel selection...

Marleau, L. J., Sutherland B.R., Flynn, M.R.
Bottom propagating gravity currents resulting from full- and partial-depth lock-release experiments are investigated as they approach and then propagate up a rising slope. Consistent with the prediction of a WKB-like theory, the gravity current front decelerates in a nearly uniform manner along...

Investigation into the effects of stainless steel ligature ties on the mechanical characteristics of conventional and self-ligated brackets subjected to torque
Download2014
Heo, Giseon, Nobes, David S., Al Fakir, Hussam, Major, Paul W., Melenka, Garrett W., Carey, Jason P.
Objective: Torque is applied to orthodontic brackets in order to alter the buccal-lingual angulation of a tooth. One factor that can affect torque is the ligation mode used to retain the archwire in the bracket slot. The objective of this study was to investigate the effects of stainless steel...

Forst, Darren, Nijjar, Simrit, Flores-Mir, Carlos, Carey, Jason, Secanell, Marc, Lagravere, Manuel
The objective of this study is to analyze a set of previously developed and proposed image segmentation protocols for precision in both intra- and inter-rater reliability for in vivo tooth volume measurements using cone-beam computed tomography (CBCT) images. Six 3D volume segmentation procedures...

Initial experimental and theoretical investigation of solar molten media methane cracking for hydrogen production
Download2014-01-01
Paxman, D., Trottier, S., Nikoo, M., Secanell, Marc, Ordorica-Garcia, G.
Previous work assessed the fundamental technical and market risks associated with the development and deployment of solar fuels technology in Alberta. It identified methane cracking in solar-molten media as the hydrogen production technology featuring the best combination of technical risk,...

Secanell, Marc, Lagravère, Manuel O., Nijjar, Simrit, Carey, Jason P., Forst, Darren, Flores-Mir, Carlos
Background The objective of this study is to analyze a set of previously developed and proposed image segmentation protocols for precision in both intra- and inter-rater reliability for in vivo tooth volume measurements using cone-beam computed tomography (CBCT) images. Methods Six 3D volume...

The Effects of Microstructure and Confinement on the Compressive Fragmentation of an Advanced Ceramic
Download2014
Farbaniec, Lukasz, Shaeffer, Matt, Ramesh, K.T., Hogan, James
We investigate the rate-dependent compressive failure and fragmentation of a hot-pressed boron carbide, under both uniaxial and confined biaxial compression, using quantitative fragment analysis coupled with quantitative microstructural analysis. Two distinct fragmentation regimes are observed,...

Impact Failure of Planetary Materials: Lateral Field Ejecta Measurements using Particle Image Velocimetry
Download2014
Schneider, Markus, Spray, John, Rogers, Robert, Hogan, James, Vincent, Gregory
The dynamic fragmentation of a fine grained granitoid material has been examined. Target thicknesses ranged from 7 to 40 mm and impact energies from 12 to 2,500 J. Combined particle image velocimetry and image enhancement techniques are introduced and have been used to measure the size and...

The effect of perturbations on resistance to sliding in second order moments comparing two different bracket types
Download2014
Wong, Justin W., Carey, Jason P., Romanyk, Dan L., Heo, Giseon, Toogood, Roger W., Major, Paul W.
Orthodontic literature has shown all ligation methods to behave similarly in the clinical situation; however, the reasoning behind this still requires further investigation. A novel frictional device able to measure forces at the level of the bracket along with a custom perturbation device was...
