Time Domain Principal Component Analysis for Rapid, Real-Time 2D MRI Reconstruction from Undersampled Data
DownloadSpring 2022
Hybrid Linac-MR systems are becoming more mainstream for use in external beam radiotherapy treatments for cancer patients. The addition of an MR scanner to a linear accelerator (Linac) can allow for real-time structure tracking (such as a tumour) and on-the-fly adjustments of the radiation beam....

Logistic and economic constraints often dictate the spatial sampling of a seismic survey. The process of acquisition records a finite number of spatial samples of the continuous wave field. The latter leads to a regular or irregular distribution of seismograms. Seismic reconstruction methods are...

Long-term agronomic and environmental impact of aspen control strategies in the Aspen Parkland
DownloadFall 2010
Since European settlement the Aspen Parkland has been subject to agricultural intensification. This research assessed the agronomic, ecologic and economic impact of native Parkland conversion into tame pasture, by building on a study initiated in 1980 investigating the short-term agronomic...

Exploration seismology utilizes the seismic wavefield for prospecting oil and gas. The seismic reflection experiment consists on deploying sources and receivers in the surface of an area of interest. When the sources are activated, the receivers measure the wavefield that is reflected from...

The effects of underplanted white spruce on understory environment and vegetation in aspen-dominated stands of the western boreal forest
DownloadSpring 2012
In the boreal forest of Alberta, Canada, underplanting white spruce (Picea glauca) in aspen (Populus tremuloides) forests attempts to address concerns about "unmixing the mixedwoods". Important ecological differences exist between mixedwood, broadleaf and conifer forests. I studied changes in...

Impact of seedling characteristics, outplanting time, and container size on early establishment of aspen (Populus tremuloides) on reclamation sites
DownloadFall 2011
Aspen seedlings often suffer from transplant shock after outplanting. The influence of seedling characteristics and time of outplanting (spring, summer and fall) on field performance was examined on mining reclamation sites. Seedling characteristics were modified by inducing premature bud set...

The effects of subsoil ripping on soil physical properties and soil water dynamics on reconstructed soils at Genesee Prairie Mine, Alberta
DownloadSpring 2014
Surface mining activities have significantly depleted natural tree cover, especially trembling aspen (Populus tremuloides), in the Boreal Forest and Aspen Parkland Natural Regions of Alberta. The natural soil profile is usually destroyed during these mining activities and soil and landscape...

The Short-term Impacts of Aspen Clear-cutting on Upland Groundwater RechargeClear-cutting Impacts on Groundwater Recharge
DownloadSpring 2011
The impacts of aspen clear-cutting on upland groundwater recharge are presented based on two years (2007-2008) of the five year (2005-2009) HEAD2 NSERC-CRD paired-catchment experiment. Research was conducted at the Utikuma Region Study Area (URSA), 370 km north of Edmonton, Alberta, Canada, in...

Disturbance Effects of Oil Sands Exploration Practices on Coarse-textured Soils and Populus tremuloides Michx. Regeneration
DownloadSpring 2018
Oils sands exploration (OSE) sites associated with in situ oil sands development are required to evaluate and delineate oil resources. Once these sites are cleared and disturbed for exploration, they can result in habitat disturbance and fragmentation, invasion of weed species, changes to surface...
