Flynn, M.R., Onu, K., Sutherland, B. R.
Abstract. Synthetic schlieren is a new technique that allowsone easily and inexpensively to visualise density variations, such as those caused by internal waves propagating in a density stratified fluid. In the special case of twodimensional internal waves (for example, those created by an...

Gravity currents propagating up a slope in a two-layer fluid
2004
Sutherland, B.R, Marleau, L. J., Flynn, M.R.
Gravity currents produced by partial-depth lock-release and travelling along the base of a two-layer stratified ambient are investigated as they propagate along a rising slope. The initial gravity current front speed is found to be consistent with a theory adapted from Shin et al. [“Gravity...

In traditional reliability theory, both the system and its components are allowed to take only two possible states: working or failed. In a multi-state system, both the system and the components are allowed to be in M+1 states: 0, 1, 2,…, M, where M is a positive integer which represents a system...

Density Conversion Factor Determined using a Cone-Beam Computed Tomography Unit NewTom QR-DVT 9000
Download2006
Carey, Jason, Lagravère, Manuel O., Major, Paul W., Fang, Y., Packota, Garnet V., Toogood, Roger W.
Objective: The purpose of this study was to determine a conversion coefficient for Hounsfield Units (HU) to material density (g cm−3) obtained from cone-beam computed tomography (CBCT-NewTom QR-DVT 9000) data. Methods: Six cylindrical models of materials with different densities were made and...

Major, Paul, Carey, Jason, Russett, Shawn, Toogood, Roger, Boulanger, Pierre
Reproduction of anatomical structures by rapid prototyping has proven to be a valid adjunct for craniofacial surgery, providing alternative methods to produce prostheses and development of surgical guides. The aim of this study was to introduce a methodology to fabricate asymmetric human...

Clinical variability in arch wires: A preliminary study evaluating mechanical and surface characteristics of two different sized rectangular stainless steel wires
Download2007
Vena, Alessandro, Carey, Jason, Badawi, Hisham
Experimental characterization of arch wires has been performed in many previous studies; however with the advent of new arch wire materials being introduced, some new experimental methods and characterization are required. Since literature is available for comparison, this paper examines...

Kerstein, Robert B., Carey, Jason P., Craig, Mark, Radke, John
Articulating paper mark size has been widely accepted in the dental community to be descriptive of occlusal load. The objective of this study is to determine if any direct relationship exists between articulating paper mark area and applied occlusal load. A uniaxial testing machine repeatedly...

Gearbox Fault Feature Extraction Using Hilbert Transform, S-Transform, and a Statistical Indicator
Download2007
Vibration analysis has been widely used in machine fault feature extraction and diagnosis of rotating machinery. The effects of modulation and nonstationarity in vibration signals collected from a faulty gearbox present challenges for fault feature extraction. Hilbert transform and S-transform...

Effect of object location on the density measurement and hounsfield conversion in a NewTom 3G cone-beam computed tomography unit
Download2008
Ben-Zvi, Micha, Packota, Garnet V., Major, Paul W., Lagravère, Manuel O., Carey, Jason
Objectives: The purpose of this study was to determine the effect of an object's location in a cone beam CT imaging chamber (CBCT-NewTom 3G) on its apparent density and to develop a linear conversion coefficient for Hounsfield units (HU) to material density (g cm−3) for the NewTom 3G Scanner....

FEM Simulation of Non-Progressive Growth from Asymmetric Loading and Vicious Cycle Theory: Scoliosis Study Proof of Concept
Download2010
Fok, Jonathan W., Carey, Jason P., Adeeb, Samer
Scoliosis affects about 1-3% of the adolescent population, with 80% of cases being idiopathic. There is currently a lack of understanding regarding the biomechanics of scoliosis, current treatment methods can be further improved with a greater understanding of scoliosis growth patterns. The...
