Design and Optimization of a 1 kW Hybrid Powertrain for Unmanned Aerial Vehicles

Creator:: Brown, Sean P.
Abstract:: A 1 kW series hybrid powertrain was developed at Oregon State University for use in unmanned aerial vehicles (UAVs). This powertrain was designed to give mission flexibility and increased flight time to fixed-wing vertical takeoff and landing UAVs and multirotor UAVs. The powertrain components, an internal combustion engine and a...

Problem Solving Personas of Civil Engineering Practitioners using Eye Tracking Techniques

Creator:: Gestson, Sean L.
Abstract:: Engineering practitioners solve problems in various ways; it is plausible that they often rely on graphs, figures, formulas and other representations to reach a solution. How and why engineering practitioners use representations to solve problems can characterize certain problem-solving behaviors, which can be used to determine particular types of problem...

Stephen Biko's Rhetorical Vision of Black Consciousness

Creator:: Fergusson, Julie K.
Abstract:: Stephen Biko was a black leader in South Africa who died in police custody on September 12, 1977. Biko's death echoed within the Republic of South Africa and around the world, showing that racial tensions in that country were severe. At his death he was a hero to the black...

Aerobic Cometabolism of 1,4-Dioxane and cis-Dichloroethylene by Gellan Gum and Polyvinyl Alcohol/Sodium Alginate Hydrogel Beads Co-Encapsulated with Rhodococcus rhodochrous Strain ATCC 21198 and Slow-Release Growth Substrates: Batch, Column, and Toxicity Studies

Creator:: Conway, Sean P.
Abstract:: 1,4-Dioxane (dioxane) and cis-dichloroethylene (cDCE) are compounds commonly found in industrial cleaning and degreasing agents that are frequently present as groundwater contaminants. In an effort to develop a more effective treatment method for these compounds, hydrogel beads were fabricated with either gellan gum or a combination of polyvinyl alcohol (PVA)...

Modeling, simulation, and analysis of two hydraulic power take-off systems for wave energy conversion

Creator:: Casey, Sean (Sean Michael)
Abstract:: Hydraulic power take-off (PTO) systems have been implemented in several wave energy converter (WEC) designs in recent years. Two popular hydraulic PTO configurations coupled to a point absorber hydrodynamic model are simulated in waves representative of an energetic sea state likely to be found in deep waters off the coast...

An Exploration of Faculty Sensemaking in the Adoption of Course Social and Cognitive Engagement (CSCE) Surveys

Creator:: Ironside, Allyson J.
Abstract:: The work of engineering education researchers has resulted in the development of research-based instructional strategies (RBISs) aimed at providing educators with means to increase student learning. Research has shown that there is a disconnect between the development of RBISs and their use by educators. Means to make new practices more...

Crown structure, stand dynamics, and production ecology of two species mixtures in the central Oregon Cascades

Creator:: Garber, Sean M.
Abstract:: Knowledge of stand structure, stand dynamics, and production ecology of species mixtures lags well behind that of single-species, even-aged stands. Two mixed-species spacing trials in central Oregon allowed investigation of mixed-species dynamics in a controlled experimental setting. The first site, Pringle Butte, is a mixture of ponderosa pine (Pinus ponderosa...

Cytochrome P-450 monooxygenases in the mosquito, Culex pipiens

Creator:: Baldridge, Gerald D.
Abstract:: A sucrose density-gradient ultracentrifugation technique for obtaining microsomes has been developed. This technique has advantages over the classic differential centrifugation technique, in that it is faster, is better suited to work with small quantities of tissue, and offers the opportunity to work with a defined microsomal sub-cellular fraction, rather than...

Distribution and coinfection of microparasites and macroparasites in juvenile salmonids in three upper Willamette River tributaries

Creator:: Roon, Sean Robert
Abstract:: Wild fish populations are typically infected with a variety of micro- and macroparasites that may affect fitness and survival, however, there is little published information on parasite distribution in wild juvenile salmonids in three upper tributaries of the Willamette River, OR. The objectives of this survey were to document (1)...
