Spring 2014
This work provides a guideline for gecko inspired dry adhesive design and simulation. Mechanical property testing for several polymers commonly used in gecko adhesives (Kraton G1657 thermoplastic elastomer, ST-1060, and ST-1087 polyurethane elastomers) allowed hyperelastic and viscoelastic...

Stainless steel is one of the most commonly used materials in most industries. Excellent corrosion resistance of stainless steel is due to the formation of an oxide film on the surface (passive film), which protects the material from continuous corrosion attacks. When subjected to an attack...

Evaluation of Different Winter Road Conditions and Effectiveness of Winter Road Maintenance Operations
DownloadFall 2014
This study uses friction measurements of Real Time Traction Tool (RT3)-Curve to characterize different road conditions, evaluate the effect of winter maintenance operations, and identify influential parameters. The reliability of RT3-Curve device was verified by a speed-dependency analysis....

Geomorphic landform design and long-term assessment of tailings storage facilities in the Athabasca oil sands
DownloadFall 2019
In stark contrast to historic mine abandonment, current international best practices in mine reclamation call for geomorphic designs and stability (physical and chemical) for a minimum of 1000 years. Current regulations in Alberta state that post-mining landforms shall be maintenance-free with...

Fall 2016
Slurry pipelines are widely utilized in most mining operations to transport the raw materials and the tailings. These pipelines typically suffer from high wear rates. For example, in Canada’s oil sands industry, pipeline wear rates of 1 cm/yr are considered representative. To generate and measure...

Investigation Using Polymer Additives to Mitigate Erosion in Multiphase Turbulent Pipe Flow
DownloadSpring 2019
Long chained polymers were evaluated for their impact on reducing pipe erosion during two-phase flow. The research study was compartmentalized into three categories. One of the components of this study investigated the erosion of different materials in an attempt to find a faster eroding...

Road Erosion, Sediment Delivery, and Consequence in the Simonette Watershed West-Central Alberta
DownloadSpring 2022
Gravel and dirt resource roads in the Alberta foothills are critical economic infrastructure, used to explore for, manage, and extract natural resources from this region. Resource roads are also known to add sediment to nearby streams and rivers, causing habitat stress for fish. Understanding...

The Effect of Conventional Elastomers on Force and Moment of a Self-Ligating Orthodontic Bracket with Second-Order Angulation in the Dry and Wet States evaluated through a new 3D Friction Device
DownloadSpring 2013
Objective: A new three-dimensional friction device was used to investigate the effect of conventional elastomers on force and moment of a self-ligating orthodontic bracket with second-order angulation during a simulated retraction. Methods: An 0.018x0.025-in stainless steel archwire was drawn...

The Effect of Perturbations on Resistance to Sliding in Second Order Moments Using Conventional Ligated Brackets Versus Passive Self Ligated Brackets
DownloadFall 2013
Abstract Objectives: A novel frictional and perturbation device was used to investigate the role of vibrations on resistance to sliding (RS) in conventional and passive ligated brackets Methods: 150 3M Victory Series twins (0.022 slot) and 150 Damon Q brackets (0.022 slot) were tested using an...
