Incorporating climate change uncertainty into transportation infrastructure investment decisions
DownloadFall 2019
The Mackenzie River is a historically important transportation corridor of the Northwest Territories, allowing for barge freight transport to remote communities throughout its length. However, more recently, climate change has affected the duration of the Mackenzie River’s navigational season,...

A study of the colloidal stability of mixed abrasive slurries of silica and ceria nanoparticles for chemical mechanical polishing
DownloadFall 2011
Slurry stability is an important factor in Chemical Mechanical Polishing (CMP) efficiency. However, few studies have been done in this respect. In settling tests at pH 4, adding various amounts of ceria to colloidal silica slurries was shown to change the stability of the resulted mixed abrasive...

Crane lift path planning is time-consuming, prone to errors, and requires the practitioners to have exceptional visualization abilities, in particular, as the construction site is congested and dynamically changing. This research presents a methodology based on robotics motion planning to...

Extended shear tab connections are efficient for both fabrication and erection where a beam would otherwise need to be coped to clear the flanges of the supporting member, and are therefore used extensively in industry. Stability issues can arise as the plate becomes longer and more slender, as...

Assessing and Catalyzing Adoption and Implementation of the Alberta Nutrition Guidelines for Children and Youth in Recreational Sports Settings
DownloadSpring 2014
Although the mandate of recreational sports settings is to enhance well-being, many have unhealthy food environments that may paradoxically increase obesity risk. The Alberta Nutrition Guidelines for Children and Youth (ANGCY) are government-initiated, voluntary guidelines intended to facilitate...

Clipping and Watering Effects on Caespitose and Rhizomatous Grasses: Implications for Grazing Management
DownloadSpring 2014
Recent experimental evidence suggests that rotational grazing, despite strong perceptions to the contrary, does not promote plant community productivity relative to continuous grazing on rangelands. However, clipping studies from tame pastures of Alberta’s Aspen Parkland show clear plant...
