Impacts of aggregated retention harvesting on the diversity patterns of nocturnal moth species assemblages in the mixedwood boreal forest of northwestern Alberta
DownloadFall 2012
The loss of mature forest habitat from forest harvesting represents a substantial threat to the diversity of nocturnal boreal forest moth assemblages. In this study, I used spatial patterns of species diversity to quantify the effects of aggregated green tree retention harvesting on the diversity...

Lejoly, Justine Daniele Marthe
Exotic species of earthworms are invading North American forests, where native earthworms were extirpated by the last glaciation. The invasion of these ecosystem engineers can alter soil organic matter (SOM) dynamics, carbon (C) persistence, and ecosystem functioning. While the topic has been...

Natural Recovery of Upland Boreal Forest Vegetation on a Hummocky Peat-Mineral Mix Substrate in the Athabasca Oil Sands Region, Alberta
DownloadSpring 2010
This research investigated the natural recovery of upland boreal forest vegetation on a peat-mineral mix substrate in the Athabasca Oil Sands Region, Alberta. Three sites, aged 26 to 34 years, were assessed to determine effects of substrate (pH, electrical conductivity, texture), topography,...

Spring 2013
A major barrier to reclamation after oil sands mining is lack of commercially available, diverse native plant seeds and propagules for revegetation. Potential of LFH (forest floor material) developed on coarse textured soil for establishing native plants and how salvage, placement and storage...

Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...

Real-Time Electromagnetic Transient Hardware Emulation of Multi-Terminal High Voltage DC Grid
DownloadFall 2018
New high voltage DC (HVDC) transmission projects are being increasingly operated globally, which can be developed into multi-terminal DC (MTDC) grid interconnecting the conventional AC grid and the off-shore renewable energy power plants. Among various power converter topologies, modular...

Real-Time Hardware-in-the-Loop Emulation of Electric Machines for Electrified Transportation Systems
DownloadFall 2018
Design and prototyping of electric power components and systems employing off-line transient simulation tools are inefficient due to, first, time consumption of sequential processors for several cycles of testing, and second, inaccuracy arising from simplifications in the modeling of the entire...

Real-Time Nonlinear Frequency-Dependent Electromagnetic Transient Power Transformer Model Hardware Emulation
DownloadSpring 2016
A transformer is a vital piece of transmission and distribution infrastructure in a power system which is used to transfer energy from one circuit to another. Real-time electromagnetic transient (EMT) simulation plays an important role in the design and testing of protection and control systems...

Reproduction and abundance of the wood frog (Lithobates sylvaticus) in post-harvest variable retention forests
DownloadFall 2017
Many aquatic-breeding amphibians require freshwater habitat for reproduction and terrestrial habitat for refuge, foraging, and overwintering. Variable retention harvesting is a technique where live trees and other forest features are retained during timber harvesting in patterns that emulate...

Simulation of quantization noise effects on the performance of a wireless preamble detector and demonstration of a functional FPGA prototype
DownloadFall 2009
This thesis describes the implementation of the physical layer for an experimental low-power wireless communication device. The system utilizes differential coherent correlation and threshold-based detection to produce a robust random-access packet-based communications protocol. Prior to...
