A 4D filtering and calibration technique for small-scale point cloud change detection with a terrestrial laser scanner
Download2015
Hutchinson, D. Jean, Kromer, Ryan A., Edwards, Tom, Lato, Matt, Jaboyedoff, Michel, Abellán, Antonio
This study presents a point cloud de-noising and calibration approach that takes advantage of point redundancy in both space and time (4D). The purpose is to detect displacements using terrestrial laser scanner data at the sub-mm scale or smaller, similar to radar systems, for the study of very...

A comparison of passive monitoring methods for gray wolves (Canis lupus) in Alberta, Canada
DownloadSpring 2019
Remote camera traps are often applied to large mammal conservation and management programs because they are cost-effective, allow for repeat surveys, and can be deployed for long time periods. Additionally, statistical advancements in calculating population metrics, such as density, from camera...

A laboratory study of long-term effects of mine depressurization groundwater on fish and invertebrates
Download1980-01-01
McCart, P. J., Tsui, P. T. P., McMahon, B. R., McCart, J. V.
This study was conducted to determine long-term toxic effects, on selected species of fish and invertebrates, of mine depressurization at concentrations non-lethal in acute toxicity tests. The study also includes chronic toxicity experiments, studies of sublethal effects of groundwater, and a...

A.A. Aquatic Research Ltd., R.L. & L. Environmental Services Ltd.
Syncrude Canada Ltd., which has operated an oil sands extraction plant at Mildred Lake since 1978, has undertaken various environmental studies associated with the development since 1971. The purpose of the 1984 investigation, which involved a multi-disciplinary study team, was to characterize...

The colonization of limestone bricks and bitumen coated limestone bricks by benthic river organisms was followed over time. After nine weeks of colonization, no massive increase in the numbers of bacteria on the bitumen was noted, suggesting that degradation was not proceeding rapidly. However,...

Adolescent Idiopathic Scoliosis: Classifying, Assessing, and Monitoring using Surface Topography Asymmetry Analysis
DownloadFall 2014
The radiation dose and the associated lifetime risk of developing cancer is a problem justifying the use of surface topography (ST) as an alternative to radiographs for monitoring scoliosis. The current ST methods mainly rely on marker placement and fail to describe the 3D aspect of the scoliosis...

Algorithms for Adolescent Idiopathic Scoliosis Classification Based on Surface Topography Analysis
DownloadSpring 2018
While the common method for diagnosing and monitoring adolescents with idiopathic scoliosis (AIS) is X-ray radiographs from which a Cobb angle is measured, studies have shown that high radiation exposure is linked to high risk of cancer, particularly, for children and women. This thesis describes...

Yarranton, G. A., Wallace, R. R., Davis, C. S., Crowther, R. A., Davies, M. J. E., Stevens, D. L. M., Caton, R. B.
Alberta Environment is in the process of reviewing the scientific and technical basis for refinement of a regulatory approach to the environmental impact of present and future industrial development in the Athabasca oil sands region. The review has encompassed the results of 10 years (1975 to...
