Fail-Safe Logic Design Strategies Within Modern Fpga Architectures, Priya A. Bhakta

Electrical and Computer Engineering ETDs

Field Programmable Gate Arrays (FPGAs) are vulnerable to radiation-induced single event upsets (SEUs) and fault injection attacks, requiring the use of redundancy techniques such as fail-safe computing. Fail-safe computing refers to computing systems that revert to a non-operational safe state when a fault occurs. This work investigates circuit-level techniques and implements fail-safe computing processes as mitigation for SEUs and fault injection attacks on FPGAs. The analysis reveals vulnerabilities that exist in FPGAs over those in application-specific integrated circuits (ASIC); thus, requiring a more elaborate network of redundant circuits and checking logic. The reconfiguration capability of FPGAs adds complexity to fail-safe …

Modelling V-Band Atmospheric Loss With Deep Learning, Ralph Lyndon Gesner

Electrical and Computer Engineering ETDs

Modelling atmospheric loss is fundamental to implementation of future mm-wave terrestrial and earth space communication links. Atmospheric losses have traditionally been estimated by calculating the contributions of individual weather phenomena through in-situ meteorological measurements and statistically derived models for estimating localized atmospheric water content. Collecting data for all points along the propagation path and calculating the physical effects of gases, clouds, and precipitation individually is both time consuming and impractical for large-scale use cases.

In response to these present limitations, this work proposes the use of novel deep learning models for estimating atmospheric losses from tabular meteorological sensor data and …

Operations On Submodules With The Multiplicative And Quotient Properties, Jiekai Pang

Mathematics & Statistics ETDs

Inspired by the works of Petro, Epstein, Vassilev, and Morre, this thesis aims to study the generalized definitions of the semiprime operation, weakly prime operation, and standard closure operation on rings, that is, the multiplicative operation, weakly multiplicative operation, and standardly multiplicative operation on submodules. Then, we will use Matlis duality to induce the dual notions of these definitions on submodules of Matlis-dualizable Artinian modules. In order to understand the dual notion of the standardly multiplicative operation, that is, the standardly quotient operation, we will classify the operations on the injective hull of residue field of the ring K[[x,y]]/(xy) which …

Tnf Prevents Establishment Of Anti-Tumor Immunity And Elucidates Toxicities Following Myxoma Virus Based Oncolytic Virotherapy, Miriam Beatriz Valenzuela Cardenas

Biomedical Sciences ETDs

Tumor Necrosis Factor Alpha (TNF) can lead to tumor regression through its direct cytolytic activity, yet it has also been implicated to facilitate tumor progression. This scenario complicates the efficacy and applicability of TNF based therapeutics as treatment for malignancies. In the context of oncolytic virotherapy (OV) which uses replicating viruses to treat tumors and acts by triggering production of pro-inflammatory cytokines, exploring such mechanisms is vital. Here we show that a Myxoma based oncolytic virus (vPD1/IL12) can induce large amounts TNF. The presence of TNF in the context of vPD1/IL12 plays a detrimental role both for tumor regression by …

Evaluation Of Electrode Configurations For (0,2) Piezoelectric Ultrasound Transducers, Abdul Qayoum Popal

Mechanical Engineering ETDs

Piezoelectric micro ultrasound transducers (PMUT array) are pivotal in MEMS applications. They typically operate in the fundamental (0,1) acoustic mode and are not significantly researched for higher modes (0,2) and (0,3). Similarly, vibrating mesh atomizers (VMAs) demand the second (0,2) mode and third mode (0,3) for effective aerosol generation, highlighting the need for optimized electrode configurations—a relatively unexplored area. This study presents the first comprehensive analysis of how electrode designs influence PMUT performance in the (0,2) mode for VMA applications.

Utilizing COMSOL multiphysics finite element modeling (FEM) with residual stress considerations alongside experimental validation, we demonstrate that optimized electrode configurations …

Targeting Myeloid Cell Iron Metabolism In Salmonella-Induced Colitis, Mariella Arcos Padilla

Biomedical Engineering ETDs

Salmonellosis is a severe infection caused by Salmonella enterica serovar Typhimurium, leading to significant global morbidity and mortality.

Previous studies have shown that mice lacking the iron storage protein ferritin heavy chain (FTH1) in myeloid cells exhibit worsened Salmonella infection. Nuclear receptor co-activator 4 (NCOA4) directs FTH1 autophagic degradation to release iron from storage during conditions of low iron. However, the role of myeloid NCOA4 in regulating bacterial infections remains unclear.

Here, we found that myeloid NCOA4 deficiency augments spleen iron levels and increases cellular iron accumulation, oxidative stress, and ferroptosis in bone marrow-derived macrophages (BMDM) cells. This deficiency also …

Electrical and Computer Engineering ETDs

Non-Gaussian uncertainty frequently arises in learning and control problems involving stochastic dynamical systems, particularly in autonomous vehicles, UAVs, satellites, and robotics. In this dissertation, we propose a new framework that leverages characteristic functions that provides a frequency-domain representation of random variables. The dissertation is structured into three key areas. First, we address model-based stochastic optimal control for linear systems with non-Gaussian noise, demonstrating that characteristic functions can be used to enforce chance constraints and control systems toward desired distributions. Second, we explore data-driven stochastic control, utilizing empirical characteristic functions to handle systems with unknown disturbances. In addition, we derive several …

Modern Agricultural Servitude: The Modern Farm Worker Experience In The Salinas Valley, Jesus E. Tavarez

Ready, Set, Woes: A Narrative Inquiry Into Special Education Teacher Attrition By Transfer To General Education, Brent G. Collom

Teacher Education, Educational Leadership & Policy ETDs

Despite the prevalence of unfilled special education teaching positions nationwide, it is fair to ask whether there is truly a shortage of special education teachers (SETs). While SETs leave education at high rates, they are almost twice as likely to transfer to general education positions. Many former SETs are employed in schools yet outside of special education.

This narrative inquiry examined the stories of 10 former SETs who transferred to general education. This study found that former SETs continue to identify as teaching special education. Former SETs want general education teachers (GETs) and administrators to have training in special education …

Custom Cathode Optimization For Electropolishing Additively Manufactured 316l Stainless Steel, Kasandra Escarcega Herrera

Mechanical Engineering ETDs

Laser powder bed fusion (LPBF) has become increasingly popular for its ability to rapidly manufacture complex metallic parts. However, the surface properties of as-built LPBF parts may degrade overall performance due to tortuous surface features. Consequently, post-processing like electropolishing (EP) to reduce the surface asperities is often needed for LPBF parts to perform as expected. Utilizing experimental and computational approaches, this project aims to more uniformly EP complex shaped parts made from LPBF 316L. For the experimental approach, parts with a three-dimensional T-shape were printed out of 316L stainless steel and EP using an acidic-based and a polyethylene glycol/NaCl-based electrolyte. …

Hypoxia-Inducible Factor 3Α1'S Role In Promoting Iron Loading, Tumorigenesis, And Metastasis In Colorectal Cancer, Luke B. Villareal

Biomedical Sciences ETDs

The interplay between hypoxia and iron metabolism drives colorectal cancer (CRC) progression. This dissertation investigates hypoxia-inducible factor 3α1 (HIF-3α1), a protein linked to poor CRC outcomes, focusing on its roles in metastasis, epithelial-to-mesenchymal transition (EMT), and iron loading via transferrin receptor (TFRC). HIF-3α1 promotes CRC cell migration by upregulating zinc finger E-box binding homeobox 2 (ZEB2) and suppressing N-myc downstream-regulated gene 1 (NDRG1), while TFRC-mediated iron accumulation supports tumor growth and survival. Iron chelation reduced EMT markers, migration, and tumor growth, highlighting iron's critical role. Additionally, HIF-3α1-induced TFRC expression altered nucleotide synthesis enzymes carbamoyl-phosphate synthetase-aspartate transcarbamoylase-dihydroorotase (CAD) and phosphoribosyl pyrophosphate …

Validation Of A Culturally Adapted Neuropsychology Screening Measure Among Older American Indians, Katherine A. Edwards

Psychology ETDs

American Indian (AI) older adults are most at risk of developing Alzheimer’s disease and other dementias in the United States. However, there are no cognitive screening tools validated or normed for AI populations, limiting the diagnostic accuracy of current tools. In this study, a culturally adapted screening tool was adapted for three different sites with older AI adults, and validated against widely used neurocognitive screening measures to determine convergent validity. Results found that adapted story memory scores were significantly higher than unadapted scores. Additionally, culturally salient story memory scores were more consistent with measures of crystalized intelligence, while unadapted story …
