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...

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...

The Ripley Landslide is one of the smallest among the 12 landslides at the Ashcroft-Thompson River Valley, located approximately 10 km south of Ashcroft, B.C. Since it was first identified in 1951, it has been studied by numerous researchers to understand the kinematics controlling its behaviour....

This study assessed the level of secondary production in the Muskeg River and tested the validity of hypotheses generated by Crowther and Griffing (1979) regarding the trophic structure and function of the Muskeg River as a \"typical\" tributary of the Alberta Oil Sands Environmental Research...
