Shift Register Puf Implementation On An Fpga, Sriram Thotakura

Electrical and Computer Engineering ETDs

In this thesis, a novel shift register-based physical unclonable function (PUF), called SRP, is proposed. The PUF is implemented on an FPGA and leverages the internal delay variations introduced by within-die process variations that occur within the Look-up tables (LUTs), routing and switches of the FPGA. PUFs are designed to generate bitstrings and keys on-the-fly that are device-specific (unique), random and reproducible. PUFs eliminate the need for a specialized (secure) non-volatile memory(NVM) to store the secret keys. This reduces the total cost of chips and systems, particularly those used in the Internet of Things, where it is common for systems …

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 …

How Bojack Horseman Got Too Real: Audience Engagement And A Critique Of Capitalism, Camille Le Pioufle

Foreign Languages & Literatures ETDs

What can a cartoon tell us about the state of capitalist societies? This study examines the case of Netflix adult animated TV show BoJack Horseman (2014-2020) with the aim of understanding the mechanisms at play in the formation of the critique of capitalism. It investigates the narrative and cinematographic devices employed by the show to construct a realistic portrayal of American capitalist system and its harmful consequences on individuals and society in general.

Through the analysis of realism, self-referentiality and intertextuality, the star system, and processes of subsumption and commodification, this work comes to the conclusion that BoJack Horseman ‘got …

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. …

Women’S Resilience Through Bullying Vernaculars: A Visual Vernacular Discourse Analysis, Karla Ibet Ochoa

Communication ETDs

This study shows the importance of understanding the vernaculars of resilience in relationship to bullying. In this thesis, I explore the public expressions of resilience from three women of color who experienced bullying and have become anti-bullying activists. I explore how the women construct public vernaculars of resilience and perform resilience. I drew on Feminist Standpoint Theory to conduct a visual vernacular discourse analysis of public expressions. The vernaculars discovered through analyzing the public expressions were resilience, self-expression, activism, and all voices matter. These vernaculars and performances reveal women’s feminist standpoints through the work that they do and release to …

Building Asian American And Black Solidarity For Racial Justice In Today’S America, Vinay Harpalani, Sunu P. Chandy, Sholanna Lewis, Frank H. Wu

Faculty Scholarship

About the Panel: Although there have been tensions, including those tied to colorism, between the Asian American and Pacific Islander and Black communities in America, there has been an equally long history of mutual support and collaboration between these two communities. How does anti-Blackness in the AAPI community impact the work of building solidarity with Black activists? In this conversation, we highlight our common ground so that Asian American and Black social justice communities can push forward our collective needs to fight racial injustice and other forms of discrimination in this country.

Self-Breakdown Study Of Spherical Electrodes In Air Spanning Pressures From Atmosphere To 2000 Psia, And Stress Times From Seconds To Nanoseconds, Joseph G. Felix

Electrical and Computer Engineering ETDs

In this research, a self-breakdown switch with 12.7 mm diameter spherical electrodes and a 380-micron gap was assembled and the effect of pressure and stress time on breakdown voltage and closure time were measured. Specifically, the pressure was varied from atmosphere to 2000 psia and the stress time was varied from seconds to nanoseconds. Few studies have investigated equivalent ranges of pressure and charge times on sub millimeter gap switches with electric field intensities reaching 2 MV/cm. The correlation of the parameters and switch behavior are explored in this study. In addition, the effects of humidity and electrode surface deformities …

Biopsychosocial Multidisciplinary Treatment Impact On Risk Of Opioid Misuse, Michael A. Palacio

Doctor of Nursing Practice Scholarly Projects

From 1999 to 2014, over 165,000 persons in the United States died from an overdose related to prescription opioids (Centers for Disease Control and Prevention [CDC], 2016). In response, the CDC released guidelines that propose nonpharmacologic and nonopioid pharmacologic therapy as preferred methods for chronic pain control (Dowell et al., 2016). The purpose of this project was to examine the biopsychosocial multidisciplinary treatment impact on risk of opioid medication misuse among adult chronic opioid-dependent noncancer pain clinic patients with and without a psychiatric disorder. Engel’s (1977) biopsychosocial model was used to evaluate whether multidisciplinary treatment impacted the risk of opioid …

Effects Of Message Frame And Cultural Orientations On Covid-19 Prevention Behaviors, Mika Hashimoto

Communication ETDs

This study aimed to explore effective message strategies to promote COVID-19 prevention behaviors among college students. Due to the fewer symptoms and lessened impact of COVID-19 in this population, young adults tend to have low perceived risk that results in low engagement in preventive behaviors. Also, some people may hold beliefs or values that are contrary to preventive behaviors. Thus, applying message framing theory, this study tested the effects of perceived risk and cultural orientation on adherence to prevention behaviors. The results showed that perceived risk and cultural orientation were associated with intention to maintain physical distance and wearing a …

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 …

Attitudes Towards Treating Injured Patients In Urgent Care, Erin Beverly

Doctor of Nursing Practice Scholarly Projects

There has been published literature on the topic of clinician bias and the effects of bias on patient care, however, a review of the literature did not yield any research on the topic of clinician bias towards treating patients injured in motor vehicle accidents (MVA’s). There has been concern about clinicians not preferring to see patients injured in MVA’s however this is only anecdotal. If this topic is to be addressed through quality improvement efforts, there should first be scholarly evidence to support these efforts. This study employed a prospective survey of a convenience sample of clinicians who practice in …

Regional Domesticities: Recalling, Rewriting, And Redefining Gender And Domesticity In The Greater Southwest, A. Laurie Lowrance

English Language and Literature ETDs

This dissertation examines how Native American and Mexican American women in the greater Southwest negotiated domestic expectations within their own cultures while navigating the demands of encroaching Anglo culture to produce something new: hybrid domesticities rooted in the region, which I call regional domesticities. Chapter 1 focuses on María Amparo Ruiz de Burton and connects her novels Who Would Have Thought It? and The Squatter and the Don to the rhetoric of the Overland Monthly. Chapter 2 explores bicultural collaborations between Native American and Anglo women and focuses on Sarah Winnemucca’s Life Among the Piutes and Helen Sekaqueptewa’s Me …

Stripped And Exploited Blackness: Black Nude Men In The Art Of F. Holland Day And John Singer Sargent, David P. Saiz

Art & Art History ETDs

Black representation in late-nineteenth to early-twentieth-century U.S. art and visual culture is primarily dominated by racist depictions produced by white elite (usually male) artists. Exploiting Black male nude subjects in their art production, F. Holland Day and John Singer Sargent are inextricably tied to this complicated legacy. For Day, his African series featuring U.S.-born model, J.R. Carter, extracts the subject from his time and place to present him as an exotic African subject/object. On the other hand, Sargent encounters Black Bahamian laborers at Miami’s Villa Vizcaya where he then documents his subjects in watercolor as bathers in the surrounding subtropical …

Gato Negro, Tecolote Floreado, Rosalee Montoya

Chamisa: A Journal of Literary, Performance, and Visual Arts of New Mexico and the Greater Southwest

–Era una época insólita, una época de inseguridad y una época de inquietud. Así comenzó un cuento que me contó mi abuela, Refugio, una mañana cuando era pequeña. Me dijo que, en el año 1929, comenzaron a pasar algunos incidentes extraños en Nuevo Méjico alrededor de los pueblitos de Pastura, la Pintada y hasta en partes tan lejos como en Los Montoya. Para los habitantes del llano del medio, estos eventos no tenían buena explicación según decían los que vivían allí. Siempre había permaneció la tranquilidad, paz y amistad en todo el llano. Al principio, nadie puso mucha atención cuando …

Etched-And-Regrown Diodes On M-Plane Gan For Next Generation Power Electronic Devices, Andrew A. Aragon

Electrical and Computer Engineering ETDs

Demand for next-generation power electronic devices is driven by continually evolving requirements of power systems. Devices utilizing III-nitride materials (GaN) and vertical selective-area doped architectures are advantageous due to their wide- bandgap, thermal management, small form-factor, and current handling.

Such devices incorporate junctions at multiple crystalline planes. Thus, effects of impurity contamination and etch damage are investigated on the m-plane (10-10) of GaN. Impurites (Si, O, and C) are shown to reduce blocking voltage (~ 10² ×) and increase forward leakage current (~ 10⁴ ×) in regrown versus continuously-grown p-n diodes. Elevated deep level defects at Ec – …

The Phylogeography And Molecular Systematics Of Woodrats (Genus: Neotoma) In The American Southwest, Katrina M. Derieg

Biology ETDs

The American Southwest is a region where many biomes converge, harboring a wide variety of habitats ranging from desert to alpine environments. Habitat heterogeneity and the confluence of multiple species ranges make the American Southwest a biodiversity hotspot. Climate cycling throughout the Quaternary has driven the dynamics of changes in species’ ranges that are recorded by genetic signatures. For example, range expansion may lead to secondary contact between previously isolated populations or species. Contact can result in multiple evolutionary outcomes, including hybridization or the reinforcement and maintenance of independent lineages. I used multi-locus species tree methods to re-examine the nominal …

Climatic Controls Of Plant Productivity, Phenology, And Physiology In Drylands, Alesia Jane Hallmark, Scott L. Collins, Marcy E. Litvak, Christopher D. Lippitt, Andrew D. Richardson

Biology ETDs

Drylands play a critical role in global carbon dynamics. Anthropogenic climate change is causing these hot and dry regions to become increasingly hotter, drier, and more variable. This is especially concerning as drylands are some of the most sensitive regions to changes in aridity. It is critical to understand how dryland plant species might react to a changing climate. In this dissertation, I explored the relative effects of plant community composition and dominant species abundance on determining ecosystem-wide carbon dynamics. I compared the population stability of 98 dryland plant species and related stability to phenological traits. Lastly, I related branch …

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 …
