A Paleomagnetic and Environmental Magnetic Record from the Eastern South Pacific Sector of the Southern Ocean (0-1.7 Ma): IODP Site U1543

Creator:: Monito, Lindsey
Abstract:: This research presents a u-channel based study of the natural remanent magnetization (NRM), the laboratory magnetization, Anhysteretic Remanent Magnetization (ARM), and magnetic susceptibility (k), from the upper 100 m of International Ocean Discovery Program (IODP) Expedition 383 Site U1543 in the eastern South Pacific sector of the Southern Ocean. Alternating...

Wind induced torsional fatigue behavior of truss bridge verticals

Creator:: Keller, Philipp
Abstract:: The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...

A 37,000-year record of paleomagnetic and environmental magnetic variability from Burial Lake, Arctic Alaska

Creator:: Dorfman, Jason Michael
Abstract:: Burial Lake sediments from the Noatak Basin in the northwest Brooks Range of Arctic Alaska (68.43°N, 159.17°W, 21.5 m water depth) provide the oldest continuous lacustrine record of paleo-environmental change and paleomagnetic secular variation (PSV) in eastern Beringia. A precise radiocarbon chronology, determined through accelerator mass spectrometry (AMS) allows us...

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...

Persistence of Populations in Environments with an Interface

Creator:: Rekow, James A.
Abstract:: We model a fish population in a spatial region comprising a marine protected area and a fishing ground separated by an interface. The model assumes conservation of biomass density and takes the form of a reaction diffusion equation with a logistic reaction term. At the interface, in addition to continuity...

Prototype-Scale Physical Model Study of Wave Attenuation by an Idealized Mangrove Forest of Moderate Cross-shore Width

Creator:: Kelty, Kiernan M.
Abstract:: The use of natural and nature-based features for coastal hazard mitigation, particularly emergent vegetation such as mangrove forests, have become increasingly popular. However, the protection that these systems can provide has not been fully quantified for engineering design, and the uncertainties in parameterized equations have not been fully defined. In...

Antibiotic Resistance in Septic Sludge and Receiving Environments of Ho Chi Minh City, Vietnam

Creator:: Schutzius, Genevieve Conyers
Abstract:: Approximately ninety percent of urban Vietnamese households are connected to septic tanks, from which up to three-quarters of the sludge is reported to be dumped into waterways in residential areas. Vietnam has a considerable prevalence of antibiotic misuse and resultant antibiotic-resistant bacteria (ARB) in the human microbiome. Due to the...

Implementing a Run-time Library for a Parallel MATLAB Compiler

Creator:: Malishevsky, Alexey
Abstract:: Programming parallel machines has been a difficult and unrewarding task. The short lifespan of parallel machines and their incompatibility have made it difficult to utilize them. Our goal here is to create an environment for parallel computing which allows users to take advantage of parallel computers without writing parallel programs....

Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

Creator:: Yang, Ping
Abstract:: Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...

Electromagnetic analysis of energy system devices

Creator:: Li, Yan
Abstract:: Many new applications of energy system devices have been developed to save energy, improve the controllability and stability of industrial processes, and reduce the weight, volume and cost of consumer devices. Due to the novelty of these devices, traditional empirical methods and lumped-parameter circuit theory methods are not sufficient for...
