Ultralow Velocities Of Caco3 And The Origin Of Seismic Anomalies In The Earth's Upper Mantle, Mingqiang Hou, Ming Hao, Jin Liu, Xiaowan Su, Wen-Yi Zhou, Rostislav Hrubiak, Jin S. Zhang

Earth and Planetary Sciences Faculty and Staff Publications

Calcium carbonate (CaCO₃) is a major host for CO₂ in the deep Earth. The physical and chemical properties of CaCO₃ at extreme pressure-temperature (P-T) conditions are indispensable to decipher the circulation of carbon between the Earth's interior and surface via volcanism and subduction. Using the pulse-echo-overlap method combined with Paris-Edinburgh press, we measured velocities of CaCO₃ and observed an anomalous drop associated with the amorphization of aragonite under upper mantle conditions. The compressional (V_P) and shear (V_S) wave velocities of the partially amorphized CaCO₃ are reduced …

Optimization And Characterization Of Doped Optical Fibers For Radiation Balanced Fiber Laser And Amplifier, Mostafa Peysokhan

Optical Science and Engineering ETDs

Due to the reliability, compactness, low maintenance costs, superior performance, and versatility of fiber lasers and amplifiers, they are commonly employed in scientific and directed energy applications. Among all kinds of fiber lasers and amplifiers, high-power, Yb-dopped fiber lasers and amplifiers have been extensively researched to achieve higher output powers. One of the major hindrances to achieving higher powers with adequate stability and efficiency in high power performance is heat generated in the fiber lasers and amplifiers' core. The Radiation Balanced Laser (RBL) is a viable technique for heat mitigation has been proposed by S.~Bowman in 1995. RBL technique is …

Anomaly Detection In Smart Grids Using Multi-Task Gaussian Processes, Aman Karra

Electrical and Computer Engineering ETDs

The availability of data and computing infrastructure in smart grids creates new challenges that invite solutions based on algorithmic techniques. A particular problem of interest in these systems is fault detection. It is difficult to characterize faults because of the number of different ways in which these faults can occur. Moreover, simulating a faulty mode of the system can be expensive. This work addresses fault detection by framing it as the task of detecting anomalies in the sensor data of smart grids. The assumption made is that faults are events of low probability. But no reliance is made on any …

Investigations Of Geochemical Variations With Depth At The First 15 Drill Sites On Mars Analyzed By The Chemcam Instrument Onboard The Curiosity Rover And Supported By Laboratory Studies And Analog Research At The Valle Grande Paleolake, Valles Caldera, New Mexico, Usa, Ryan S. Jackson

Earth and Planetary Sciences ETDs

The ChemCam instrument collected a wealth of data during the first 15 drill campaigns and on the distribution of trace elements at Yellowknife Bay, Mars. The drill sites investigation showed that most sites were geochemically homogenous down the depth of the drill hole. Two sites in the Stimson formation contained a vertical gradient of decreasing silica down > 3 cm. This gradient may be the result of groundwater flow and is likely recent, within 2.3 Ma. The trace element research was grounded with an analog study at the Valle Grande paleolake in New Mexico. We observed progressive alteration in the minerology …

A Practical Methodology To Detect, Quantify And Characterize Experimental Uncertainties In The Dynamic Testing Of Structures, James L. Woodall

Civil Engineering ETDs

This thesis investigates the uncertainty in the experimental context of structural dynamics. This thesis proposes a method to estimate both the effect of boundary conditions, as well as two different methods to detect the location of sensors on a specimen. Firstly, this thesis proposes a technique to predict the dynamic behavior of any point along a cantilever beam with an uncertain transverse elastic restraint. Secondly, this thesis investigates the estimation of the location of a sensor given the output data of a physical experiment with two different methods. Small errors in the sensor location may go unnoticed in the frequency …

Effects Of Environmental Change On Ancestral Pueblo Fishing In The Middle Rio Grande, Jonathan William Dombrosky

Anthropology ETDs

It has long been assumed that fishes were unimportant in the diet of past Pueblo people in the U.S. Southwest. Yet, small numbers of fish remains are consistently recovered from Late pre-Hispanic/Early Historic archaeological sites in the Middle Rio Grande of New Mexico. The end of drought conditions may have impacted food choice and fishing decisions during this time. I use behavioral ecology to understand how fishing could have been an optimal food-getting strategy for Ancestral Pueblo farmers. Stable isotope analysis offers a way to account for environmental change. I provide a refined ¹³C Suess correction model to support …

Bayesian Methods In Operational Testing: Enhancing Testing Through Combining Information, Victoria R C Sieck

Mathematics & Statistics ETDs

When developing a system, considering system performance from a user perspective can be done through operational testing|assessing the ability of representative users to accomplish tasks with the system in operationally representative environments. This critical process can be expensive and time-consuming. We show how to leverage an existing design of experiments (DOE) process to construct a Bayesian adaptive design. This method allows for interim analyses using predictive probabilities to stop testing early for success or futility. Furthermore, operational environments are directly used in product evaluation. Representative simulations demonstrate reductions in necessary test events. Next, priors are built using developmental testing data. …

Learning Intermediate Representations For Question Answering Systems, Zakery T. Clarke

Computer Science ETDs

Question answering systems are models that can perform natural language processing (NLP) on a question, retrieve an answer from a datasource, and communicate it to a user. In question answering systems, it is important for the system to learn an underlying representation for a piece of text. There are many systems that have achieved incredible accuracy on question answering datasets such as the Stanford Question and Answer Dataset (SQuAD), but these systems often encode their knowledge in a manner that is impossible to verify. Many current models would benefit more from verifiability, than marginal accuracy improvements.

We propose a method …

A Triple Oxygen Isotope Analysis Of Altered Oceanic Crust And Its Buffering Effect On The Steady State Oxygen Isotope Composition Of Seawater, Jesse P. Mcgunnigle

Earth and Planetary Sciences ETDs

The secular chemical marine sediment trend showing an increase in δ¹⁸O over geologic time has traditionally been investigated using δ¹⁸O modelling of ancient ocean compositions, ocean surface temperatures, and sample diagenetic alteration. This study presents a triple oxygen isotope mass balance for the oceans using high precision δ¹⁸O and Δ'¹⁷O measurements of altered oceanic crust. The mass balance model predicts an ice-free seawater with δ¹⁸O = -0.29‰ and Δ’¹⁷O = -0.002‰ with steady state reached at approximately (0.5 to 1)×10⁹ years. Modifications to the hydrothermal alteration and …

Implementation Of Uniform Interpolationalgorithms, Jose A. Castellanos Joo

Computer Science ETDs

This thesis discusses algorithms for the uniform interpolation problem and presents their implementation for the following theories: (quantifier-free) equality with uninterpreted functions (EUF), unit two-variable per inequality (UTVPI), and theoretic aspects for the combination of the two previous theories. The uniform interpolation algorithms implemented in this thesis were originally proposed in \cite{KAPUR2017}. Refutational proof-based solutions are the usual approach of many interpolation algorithms \cite{10.1007/978-3-642-00768-2_34, mcmillan2011interpolants, 10.1007/978-3-540-24730-2_2}. The approach taken in \cite{KAPUR2017} relies on quantifier-elimination heuristics to construct a uniform interpolant using one of the two formulas involved in the interpolation problem. The latter makes it possible to study the complexity …

Non-Gaussian Measurements Of Coherent States Of Light For Metrology And Communication, Matthew Dimario

Physics & Astronomy ETDs

Conventional measurement technology is unable to extract the most amount of information possible from coherent states of light. Non-Gaussian measurements which can count individual photons can surpass the sensitivity limits of ideal conventional strategies, and approach the ultimate limits achievable given by quantum mechanics. This thesis presents investigations and demonstrations of these unconventional measurements, which utilize coherent operations and single photon counting. This thesis shows that non-Gaussian measurements can outperform conventional strategies in estimation tasks as well as a variety of communication problems. This thesis also investigates novel approaches and algorithms for building robustness to static and dynamic noise which …

Applications Of Evidence Theory To High-Consequence Systems Safety, Christina Marie Deffenbaugh

Mathematics & Statistics ETDs

Issues linked to abnormal environments (like high-consequence systems safety, e.g., nuclear weapon components, bridges, apartment buildings, etc.) may have insufficient information to use either classical statistical methods or Bayesian approaches for calculating associated probabilistic risks, so there is often a requirement for another method that can deal with a low-information situation to obtain a risk assessment. Belief/plausibility measures of uncertainty from A. P. Dempster and G. Shafer’s Evidence Theory is one such method. This thesis has two goals. First, a brief discussion on belief/plausibility measures as an application of Evidence Theory will familiarize the audience with its history and how …

Alden, Xuechen Zhu, Ryota Shimada, Marijan Posavi, Noah Hull, Darrell L. Dinwiddie, Adam M. Halasz, Glenn Mcgall, Wei Zhou, Jeremy S. Edwards

Pediatrics Research and Scholarship

SARS-CoV-2 has infected over 128 million people worldwide, and until a vaccine is developed and widely disseminated, vigilant testing and contact tracing are the most effective ways to slow the spread of COVID-19. Typical clinical testing only confirms the presence or absence of the virus, but rather, a simple and rapid testing procedure that sequences the entire genome would be impactful and allow for tracing the spread of the virus and variants, as well as the appearance of new variants. However, traditional short read sequencing methods are time consuming and expensive. Herein, we describe a tiled genome array that we …

Diversity – Independent Factors Predict Elevated Extinction Rates, Dustin Perriguey, Corinne Myers, Jason Moore, Louis Scuderi

Earth and Planetary Sciences ETDs

Multiple linear regression was used to determine the relationships between diversity-independent factors (i.e., abiotic, climatic) 2, 5, and 10 Myrs-prior to the most elevated Phanerozoic extinctions. We constructed five abiotic variables from Phanerozoic proxy records1–5 to compare to extinction rates: mean temperature, temperature instability, carbon cycle instability, continental weathering rates, and habitat instability. All three models were statistically significant (P < 0.05) and explained > 70% of the variation in Alroy’s6 three-timer generic extinction rates. However, the 2 Myr-prior model explained the most variance in extinction rates and had the most predictive power, based on adjusted and predictive R2 (~ 72% and 41%, respectively). Carbon …
