economic feasibility of ground-based steep slope logging using winch-assist technologies
(2018)this thesis examines the use of winch-assist technologies in logging operations in the interior of british columbia. the data used for this thesis is from a contractor’s (located in central b.c.) professional judgment ... -
determining the accuracy of terrestrial lidar on red pine
(2019)this paper reviews the capabilities of the faro terrestrial lidar technology to produce accurate forest measurements. the study was conducted on single red pine trees in northern ontario. field measurements were compared ... -
causes and consequences of population changes in black bay steelhead, lake superior
(2019)understanding species interactions is an important component of fisheries resource management. like the other great lakes, lake superior’s fish species composition (and therefore interactions among species) has been changing ... -
the effects of invasive dreissenid mussels on the offshore food web of lake simcoe, ontario
(2019)dreissenid mussels have successfully invaded north america, including the great lakes and their surrounding waterbodies. with their establishment, there have been many notable impacts including the rerouting of energy flow ... -
global environmental change effects on forest dynamics: lessons from permanent sample plot networks
(2019)global environmental change caused by anthropogenic emissions of greenhouse gasses is a major threat to forest ecosystems globally. before we can begin to adequately mitigate these threats, we first must understand how ... -
petrology of ijolites from the prairie lake carbonatite complex
(2019)this study investigates the major and trace element composition of minerals of the ijolite series rocks occurring at the prairie lake carbonatite complex, northern ontario, together with comparative data for ijolites from ... -
plant diversity effect on soil carbon dynamics
(2019)soil organic carbon (soc) is a valuable natural resource, supplying goods and services for human benefits, including mediating global climate change and securing food production and environmental quality. biodiversity loss ... -
attitude and position control of flapping-wing micro aerial vehicles
(2018)compared with the fixed-wing and rotor aircraft, the flapping-wing micro aerial vehicle is of great interest to many communities because of its high efficiency and flexible maneuverability. however, issues such as ... -
coordination chemistry of bithiazole ligands: a comparative study of the 2,2’ and 4,4’ isomers
(2019)the bithiazole ring system consists of two thiazole (c3ns) aromatic rings. there are many regioisomers but two of potential interest for coordination chemistry are the 2,2’-bis(1,3-thiazole) and the 4,4’-bis(1,3-thiazole), ... -
low-power multi-band injection-locked wireless receiver
(2019)the demand for low-power high-performance wireless receivers has dramatically in- creased with the emerging deployment of wireless sensor networks (wsns). among the demodulation schemes, non-coherent receivers consume ... -
increased production of sugar streams from lignocellulosic materials through enzyme recycling
(2019)the canadian pulp and paper mills generate over 1 million tons of primary sludge per year. this sludge mainly contains small cellulosic fibers and contaminants from pulp and paper manufacture and is usually disposed of by ... -
quadrotor altitude and attitude control with neural network
(2017)over the years, the controller design for an unmanned aerial vehicle has been attracting considerable amount of attentions and interests. in this thesis, a quadcopter has been studied intensively, and an adaptive ... -
