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...

Understanding the Similarities and Differences Between Academia and the Engineering Workplace through Barriers to Adoption, Epistemic Beliefs, and Problem-Solving Behavior

Creator:: Gestson, Sean Lyle
Abstract:: Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...

Unmanned Aerial Vehicle Propulsion

Creator:: Brown, Sean
Abstract:: There is a growing US interest in UAVs for many applications ranging from agriculture to military. One area of improvement that can be realized in each category is propulsion. Engines with greater efficiency would result in longer mission duration, leading to cost savings and increased usefulness for UAV owners and...

Innovative Bioanalytical Tools & Methods for Combinatorial Non-Coding RNA Analysis

Creator:: Zhang, Lulu
Abstract:: Recently researchers have discovered that groups of small non-coding RNAs (ncRNAs) play regulatory roles in gene expression and participate in various biological processes. For example, pathogenesis of many diseases, cell cycle regulation, and signaling pathways. Intracellular and live cell imaging of small ncRNA groups will reveal their relative expression levels...

Displacement-based fluorescent microRNA biosensors : design principles and analytical metrics

Creator:: Larkey, Nicholas E.
Abstract:: One post-transcriptional mechanism that regulates the progression of cancer and other diseases involves small 22-23 nucleotide sequences called microRNA (miR). Early detection of small changes in concentration of these biomarkers holds potential to diagnose diseases at their earliest stages. Use of current nucleic-acid based biosensors, like molecular beacons, for in...

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...

Decision support systems for forest biodiversity management : a review of tools and an analytical-deliberative framework for understanding their successful application

Creator:: Gordon, Sean N.
Abstract:: The complexity of forest management has increased with the scope of resources of concern and the level of scrutiny from stakeholders. The design and use of specialized computer software, often referred to as “decision support systems” (DSS), is one method for helping managers deal with this complexity. DSS have proven...

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...
