Vortical Structures in Transition to Turbulence through Randomly Packed Porous Media: Scale, Energy, and Mixing Characteristics

Creator:: Mohammadi Ziazi, Reza
Abstract:: Vortical structures are the driving mechanism of transition to turbulence in porous media requiring adequately resolved observations along with analysis of the scale and energy of ﬂow within the pores. Of speciﬁc interest is to understand the vortex dynamics, energy, and turbulent mixing and transport properties in the scale of...

Genomic Resources for Phylogenetics, Species Delimitation, and Geographic Localization of Neotropical Tree Species Cedrela odorata L. (Meliaceae)

Creator:: Finch, Kristen N.
Abstract:: Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...

Water Governance in Afghanistan

Creator:: Rasooly, Nawid
Abstract:: Ensuring long term water security is the essential pathway towards development, prosperity, and stability in Afghanistan. However, the country is faced with water challenges that can be ascribed to governance failure at multiple levels of governance rather than to the resource base itself. Hence, studying the water governance system in...

From Micro to Macro: Insights into Biogeochemical Mechanisms that Shape Marine Systems

Creator:: Seabrook, Sarah
Abstract:: Biogeochemical mechanisms employed by key organisms, or symbiotic associations of organisms, transform the function and structure of their environment through processes recognized as ecosystem engineering. This dissertation seeks to investigate organism-ecosystem interactions that serve globally significant ecological functions in marine systems and impact how systems respond to environmental change. Using...

Movement Pattern Detection Through IMU and Barometer

Creator:: Qian, Yang
Abstract:: Movement pattern detection can be applied in a variety of applications such as assisting independent living of seniors at home, behaviour understanding in surveillance systems, sports analytics, and robotics. This project develops a scheme that fuses information from diﬀerent sensors to detect movement patterns. This report contains three main parts:...

The Impact of Portal to the Public: Creating an Infrastructure for Engaging Scientists in Informal Science Education: Summative Evaluation

Creator:: Storksdieck, Martin, Stylinski, Cathlyn, and Canzoneri, Nicolette
Abstract:: Portal to the Public (PoP) has been operated with considerable funding from the National Science Foundation since 2007 under the leadership of the Pacific Science Center (PSC). The program uses a particular model to train and support science-based professionals (“scientists”) in outreach and engagement activities, based on the premise that...

Automating Digital Human Modeling for Task Simulation and Ergonomic Evaluation to Consider Emergency Ergonomics Early in Design

Creator:: Gawand, MihirSunil
Abstract:: Digital Human Modeling (DHM) is a computational design tool that allows designers to use virtual prototypes of design for exploring ergonomics requirements. DHM brings in the advantage of reducing the time and finances committed to building the physical prototypes as well as minimizing the efforts put on performing human subject...

Investigating the Potential of Slow Release Nitrogen Fertilizer to Increase Agricultural Nitrogen Management Efficiency for Tall Fescue in the Southern Willamette Valley

Creator:: Derksen, Jacob Z.
Abstract:: Nitrogen (N) fertilizer application can promote nitrate leaching below the rooting zone and into groundwater drinking water sources in many agricultural settings. The proper management of N application can minimize non-point source nitrate pollution to groundwater. This study examines the potential for enhanced efficiency fertilizers, specifically urea treated with a...

New Metrics, Modeling Applications, and Observational Strategies for Snowpacks in Remote, Data-Limited, Mountain Environments

Creator:: Crumley, Ryan L.
Abstract:: The topics in this dissertation center on the snow processes that dominate mountain environments in the Western U.S. and Alaska, particularly in locations lacking long-term observational datasets or locales that are difficult to access in-person. Some are currently glacierized or have been glaciated in the recent past. Each of the...

Reassessment of Grading Criteria with Respect to the Flexural Properties of Douglas-fir Crossarms

Creator:: Anderson, Christopher H.
Abstract:: Wood plays a key role in modern electrical infrastructure; crossarms and power poles utilize the high strength to weight ratio, availability and low cost of wood to facilitate the access of power to millions of Americans. However, wood presents a variety of challenges as a material. In structural applications, one...
