Towards Sustainable Water Management: Soil Analysis, Modeling, And Sensor Implementation On A Micro-Basin Chile's Los Lagos Region, Tammy N. Huynh

Civil Engineering ETDs

The Los Lagos region of Chile is experiencing ecological and socioeconomic challenges because of climate change. Despite efforts by the agricultural sector to understand and manage water resources, the lack of basic water quantification data affects their ability to effectively plan and implement water management strategies. This research aims to address this critical issue through three key objectives. First, characterize soil properties related to texture and structure in a micro-basin of the Los Lagos region. Secondly, it aims to investigate the hydrologic budget of the micro-basin with an emphasis on soil moisture using the Soil Moisture Routing model (SMR). Lastly, …

Queer Crises: Movements From Queerness And Feelings Of White Religion In The United States, Austin Williams Miller

Communication ETDs

Anchored by contemporary crises surrounding queer and trans people in the United States, I employ movements from queerness within an affective queer phenomenological framework to understand how arrangements of “white religion” (Schaefer, 2015, p. 63), a process whereby U.S. American Christian forms escape ideology into religious affective economies in the United States, relegate queer people “to the background… to sustain a certain direction” (Ahmed, 2006, p. 31). I assemble a queer rhetorical context analyzing white religious space in documentary film, secular sexual regulation through contemporary U.S. legal contexts around marriage, and settler colonial Christian nationalist political imaginations to critique how …

Performance Evaluation Of E-Ticketing Technologies On Asphalt Paving Projects In New Mexico, Gena C. Robertson

Civil Engineering ETDs

The collection and processing of paper tickets for construction material delivery is an inefficient and antiquated practice that exposes inspectors on highway paving projects to substantial safety risks. An alternative to the collection of paper tickets is e-Ticketing, which uses web-based systems to deliver similar information. This research documented a current paper ticketing process and compared it to an e-Ticketing process that was implemented on several pilot projects. Data were obtained using stakeholder meetings, personnel interviews, and surveys. When compared to a paper ticketing system, e-Ticketing was shown to have fewer opportunities for error, require fewer decision points, and provide …

Investigation Of Issues Concerning Wellbore Leakage, Ishtiaque Anwar

Civil Engineering ETDs

A range of applications, such as subsurface fluid storage facilities, geothermal wells, and CO2 storage wells, are concerned about leakage along wellbores. The research described in this dissertation was largely directed toward wellbore leakage concerns for the US Strategic Petroleum Reserve (SPR). For SPR wellbores, multiple fluids are likely to exist in fractures and flow paths associated with leaky wellbores, including liquids (e.g., liquid hydrocarbon - crude oil) and gases (e.g., gas ex-solved from liquid and/or nitrogen from MIT tests). Anomalous pressure records have been observed at the wellhead of SPR wellbores, indicative of wellbore leakage. In a few cases, …

Adaptive Gps Antenna Array Beam Nulling Effectiveness Under Varying Antenna Element Positioning, Aadesh Neel

Electrical and Computer Engineering ETDs

Global Positioning System (GPS) is an essential part of modern life but is susceptible to same frequency jamming. GPS jamming can add excessive noise to a received low power signal and have the capability to change or completely distort information being sent through the GPS signal. Adaptive antenna arrays have long since been a solution to mitigating GPS jamming via beamnulling algorithms. However, there is little research on the effectiveness of these beamnulling algorithms under varying element positioning. In this work, an adaptive antenna array, consisting of Right-Hand Circularly Polarized (RHCP) nearly square GPS antenna elements, was constructed and tested …

Assessing Ecological Relationships Among Late Triassic Vertebrates In Petrified Forest National Park, Alexandra Davis Apgar

Earth and Planetary Sciences ETDs

The complex vertebrate ecosystem of the Late Triassic has not yet been fully understood, largely due to oversimplification of hypothesized trophic hierarchies and limited preservation of direct evidence of faunal interaction. Paleocommunity reconstruction attempts can also fall victim to taphonomic biases, time-averaging inaccuracies, and non-analogue paleoecologies. Utilizing a combination of PAIRS analysis and NMDS ordination, we highlight vertebrate faunal relationships within the Adamanian and Revueltian faunachrons of Petrified Forest National Park, assess the likelihood that these patterns have ecological rather than preservational drivers, and examine how these potential interactions may have been impacted by the Adamanian-Revueltian turnover event. We are …

Sensitivity And Uncertainty Analysis Of Inertial Confinement Fusion Experiments, Colin A. Weaver

Nuclear Engineering ETDs

Sandia National Laboratories conducts Magnetized Liner Inertial Fusion (MagLIF) experiments at the Z Pulsed Power Facility. Their objective is to study the burning plasma formed under magnetic direct drive Inertial Confinement Fusion (ICF) conditions and use the inferred information to reduce uncertainty in computational models and improve experimental designs. The Z machine has five neutron time-of-flight (nToF) detectors that measure the fusion neutron time spectrum from three lines-of-sight. Together, these signals are used to infer the ion temperature, target liner mass density, and the burn history of the MagLIF experiment from measured data. These parameters are a few used by …

The Bearing Earth: Colonization, Conservation, And Political Ecology In Costa Rica (Coto Brus 1948 - Present), Pablo Alonso Arias-Benavides

Latin American Studies ETDs

This thesis presents two questions: How are relationships between people in Coto Brus and the land – specifically, forest – mediated by social, political, and economic forces? How are personal and collective identities expressed through relationship with the landscape? I chose Coto Brus because it is a forested region of Costa Rica which was populated with state support in the 1950s, and because it is my father’s hometown. In order to understand the subjective experiences of Costa Ricans involved in deforestation and reforestation, I performed interviews in the canton, visited conservation sites, and analyzed historical sources. This study combines multiscale …

Optimizing High-Performance Computing Design: The Impacts Of Bandwidth And Topology Across Workloads For Distributed Shared Memory Systems, Jonathan A. Milton

Electrical and Computer Engineering ETDs

With the complexity of high-performance computing designs continuously increasing, the importance of evaluating with simulation also grows. One of the key design aspects is the network architecture; topology and bandwidth greatly influence the overall performance and should be optimized. This work uses simulations written to run in the Structural Simulation Toolkit software framework to evaluate a variety of architecture configurations, identify the optimal design point based on expected workload, and evaluate the changes with increased scale. The results show that advanced topologies outperform legacy architectures justifying the additional design complexity; and that after a certain point increasing the bandwidth provides …

Validation Of The Addictions Neuroclinical Assessment Among Diverse Individuals With Alcohol Use Disorder, Elena R. Stein

Psychology ETDs

Individuals with alcohol use disorder (AUD) are heterogeneous in terms of etiology, maintenance, symptoms, and recovery, yet current diagnostic categories fail to adequately capture this heterogeneity. Corresponding to the neurobiological addiction cycle, the Alcohol and Addictions Research Domain Criteria proposes a framework of three core domains disrupted in AUD: negative emotionality, incentive salience, and executive function. The Addictions Neuroclinical Assessment (ANA) is a hypothesized multimodal assessment battery of these three domains, which may better characterize AUD heterogeneity. The current study validated the ANA in a sample of drinkers (N=245) who were diverse with respect to ethnicity and alcohol treatment-seeking status. …

Data-Driven Porosity Prediction For Directed Energy Deposition, Georgia E. Kaufman

Electrical and Computer Engineering ETDs

Stochastic flaw formation leading to poor print quality is a major obstacle to the utility of directed energy deposition (DED), a laser and metal powder-based additive manufacturing technology for construction and repair of custom metal parts. While melt pool temperature variability is known to be a major factor in flaw formation, control schemes to decrease flaw formation are limited by a lack of physics-based models that fully and accurately describe DED. In this work, a stochastic reachability analysis with a data-driven model based on thermal images of the melt pool was conducted to determine the likelihood of violating melt pool …

Dynamic Fallowing In The Middle Rio Grande: A Look At The Environmental Water Leasing Program, Jared Wood

Water Resources Professional Project Reports

The Environmental Water Leasing Program (EWLP) is a federally-funded collaborative effort of the Middle Rio Grande Conservancy District and the U.S. Bureau of Reclamation that has paid irrigators in the Middle Rio Grande to temporarily lease water rights and forgo their water use so that it may be used to provide environmental flows for the endangered Rio Grande Silvery Minnow. The program operates in a sometimes socially contentious context, in a region with an overallocated, legally constrained water system, to offer much needed water management flexibility. While dynamic fallowing payments for ecosystem services programs like the EWLP are common policy …

Irrigation And Innovation: Understanding Barriers To Innovative Actions To Manage Drought On Middle Rio Grande Farms, Eleanor C. Hasenbeck

Water Resources Professional Project Reports

The Rio Grande has irrigated agricultural land in central New Mexico since time immemorial. Today, agriculture in New Mexico’s Middle Rio Grande valley is adapting to an increasingly scarce water supply due to long-term drought and climate change (Dunbar et al., 2022). As supply is decreasing, demands are increasing because of several factors: an increase in evapotranspiration (Dunbar et al., 2022); population growth in the Middle Rio Grande valley (NM LFC, 2021); and legal obligations to provide water for endangered species and to Texas and Mexico (NM ISC, 2017). Agriculture is largest water use by sector in the Rio Grande …

Pediatrics Research and Scholarship

Fasting is associated with increased susceptibility to hypoglycemia in people with type 1 diabetes, thereby making it a significant health risk. To date, the relationship between fasting and insulin-induced hypoglycemia has not been well characterized, so our objective was to determine whether insulin-independent factors, such as counterregulatory hormone responses, are adversely impacted by fasting in healthy control individuals. Counterregulatory responses to insulin-induced hypoglycemia were measured in 12 healthy people during 2 metabolic studies. During one study, participants ate breakfast and lunch, after which they underwent a 2-hour bout of insulin-induced hypoglycemia (FED). During the other study, participants remained fasted prior …
