The Processing and Microstructures of 309L Stainless Steel Clad onto Carbon Steel with Wire-fed Directed Energy Deposition

Creator:: Bozeman, Scott C.
Abstract:: Directed energy deposition and laser cladding technologies are suitable advanced manufacturing techniques for applying corrosion-resistant claddings to large carbon steel components. In this work, we clad 309L stainless steel wire onto carbon steel substrates and examine the effects of cladding parameters (laser power and travel speed) on metallurgical bonding, composition,...

Impact of Convective Activity on Precipitation delta O-18 in Isotope-Enabled General Circulation Models

Creator:: Hu, Jun, Emile-Geay, Julien, Nusbaumer, Jesse, and Noone, David
Abstract:: The delta O-18 signal preserved in paleoarchives is widely used to reconstruct past climate conditions. In many speleothems, this signal is classically interpreted via the amount effect. However, recent work has shown that precipitation delta O-18 (delta O-18(p)) is greatly influenced by convective processes distinct from precipitation amount, and new...

Machine Learning and Optimization Applications in Agriculture

Creator:: Molotkov, Alexander
Abstract:: The ever-increasing global population presents looming problems for the field of agriculture. Global food demand will, at some point, increase to the point where there is not enough crop-ready land to keep up. This creates an additional incentive, other than economics, for growers to increase their yield-per-acre and make sure...

Real-time Speech Workload Estimation

Creator:: Fortune, Julian D.
Abstract:: Demanding task environments (e.g., supervising a remotely piloted aircraft) require performing tasks quickly and accurately; however, periods of low and high operator workload can decrease task performance. Intelligent modulation of the system’s demands and interaction modality in response to changes in operator workload state may increase performance by avoiding undesirable...

Deep Learning Temporal Logic Specifications

Creator:: Hekkala, Claire M.
Abstract:: This thesis seeks to explain a new method of extracting temporal logic formulas from time series data using machine learning. Two strategies were followed during the development of this research: first, a generative adversarial network was combined with already-existing temporal logic extraction code by Belta. This was achieved by injecting...

Big fishery, big data, and little crabs : using genomic methods to examine the seasonal recruitment patterns of early life stage dungeness crab (Cancer magister) in the California Current ecosystem

Creator:: Lee, Elizabeth M. J. and O'Malley, Kathleen
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. Here, a genotyping-by-sequencing (GBS) approach was used to examine genomic variation in an early life stage (megalopae) of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial fishery...

Fine-scale spatial and temporal genomic variation among Dungeness crab Cancer magister larval recruits in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J. and O'Malley, Kathleen G.
Abstract:: Dynamic marine environments can shape complex spatial and temporal patterns in the population connectivity of marine species, and this is often exemplified in species with long larval phases. Here, we used a genotyping-by-sequencing (GBS) approach to examine fine-scale spatial and temporal genomic variation among Dungeness crab Cancer magister larval recruits...

Quantifying Bulk Electrode Strain and Material Displacement within Lithium Batteries via High-Speed Operando Tomography and Digital Volume Correlation

Creator:: Finegan, Donal P., Tudisco, Erika, Scheel, Mario, Robinson, James B., Taiwo, Oluwadamilola O., Eastwood, David S., Lee, Peter D., Di Michiel, Marco, Bay, Brian, Hall, Stephen A., Hinds, Gareth, Brett, Dan J. L., and Shearing, Paul R.
Abstract:: Tracking the dynamic morphology of active materials during operation of lithium batteries is essential for identifying causes of performance loss. Digital volume correlation (DVC) is applied to high-speed operando synchrotron X-ray computed tomography of a commercial Li/MnO₂ primary battery during discharge. Real-time electrode material displacement is captured in 3D allowing...

Eddy dynamics from satellite altimetry

Creator:: Fu, Lee-Lueng, Chelton, Dudley B., Le Traon, Pierre-Yves, and Morrow, Rosemary
Abstract:: Most of the kinetic energy of ocean circulation is contained in ubiquitous mesoscale eddies. Their prominent signatures in sea surface height have rendered satellite altimetry highly effective in observing global ocean eddies. Our knowledge of ocean eddy dynamics has grown by leaps and bounds since the advent of satellite altimetry...

Greater sage-grouse vital rates after wildfire

Creator:: Foster, Lee J., Dugger, Katie M., Hagen, Christian A., and Budeau, David A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) have been subject to long-term and continuing declines in population and habitat since European settlement of western North America. Increased wildfire activity constitutes a primary threat to the species in western portions of their range, with documented declines in wildfire-affected populations. Following a 187,000-ha wildfire in...
