3rd Party Ip Encryption From Netlist To Bitstream For Xilinx 7-Series Fpgas, Daniel Hutchings Aug 2023

3rd Party Ip Encryption From Netlist To Bitstream For Xilinx 7-Series Fpgas, Daniel Hutchings

Theses and Dissertations

IP vendors need to keep the internal designs of their IP secret from the IP user for security or commercial reasons. The CAD tools provided by FPGA vendors have some built-in functionality to encrypt the IP. However, the IP is consequently decrypted by the CAD tools in order to run the IP through the design flow. An IP user can use APIs provided by the CAD tools to recreate the IP in an unencrypted state. An IP user could also easily learn the internals of a protected IP with the advent of new open-source bitstream to netlist tools. The user …

An Assessment Of Cattle Traffic On, And Seed Dispersion Patterns Of, Sclerocactus Wrightiae, David D. Lariviere

Theses and Dissertations

Cattle grazing has been a historic use of rangelands in Utah since Pioneer settlement in the mid 1800's. Wright fishhook cactus is a small globose cactus endemic to an area of 280,000 ha in south-central Utah and was listed as endangered in October of 1979, by the U.S. Fish and Wildlife Service (USFWS). By 2010, concerns were expressed that soil compaction in proximity to the cactus posed a threat to this species, though there was no empirical data to support such concern. In order to assess the impact of cattle traffic on Wright fishhook cactus, we used an imprint device …

Improving Xrd Analysis With Machine Learning, Rachel E. Drapeau Aug 2023

Improving Xrd Analysis With Machine Learning, Rachel E. Drapeau

Theses and Dissertations

X-ray diffraction analysis (XRD) is an inexpensive method to quantify the relative proportions of mineral phases in a rock or soil sample. However, the analytical software available for XRD requires extensive user input to choose phases to include in the analysis. Consequently, analysis accuracy depends greatly on the experience of the analyst, especially as the number of phases in a sample increases (Raven & Self, 2017; Omotoso, 2006). The purpose of this project is to test whether incorporating machine learning methods into XRD software can improve the accuracy of analyses by assisting in the phase-picking process. In order to provide …

Side-Channel Leakage From The Advanced Encryption Standard On Field Programmable Gate Arrays, Kaden Makechnie-Hardy Aug 2023

Side-Channel Leakage From The Advanced Encryption Standard On Field Programmable Gate Arrays, Kaden Makechnie-Hardy

Undergraduate Honors Theses

As field programmable gate arrays (FPGAs) perform increasingly critical cryptography, researchers study the safety of these computations. One such compromise on the safety of cryptography is the side-channel attack. These attacks exploit sources of information called leakage that escape a cryptographic system in ways the original design did not intend. One dimension of a successful side-channel attack is the collection of leakage. This research configures the Advanced Encryption Standard (AES) on an FPGA and demonstrates strategies for collecting three types of side-channel leakage: power consumption, temperature emissions, and ring oscillations.

Predicting The Best Birds And Bees: Parental-Efficacy As A Mediator Between Parental Factors And Parent-Child Sex Communication, Meg O. Jankovich Aug 2023

Predicting The Best Birds And Bees: Parental-Efficacy As A Mediator Between Parental Factors And Parent-Child Sex Communication, Meg O. Jankovich

Theses and Dissertations

Recent literature on parent-child sex communication (PCSC) has identified optimal sex communication as being not only frequent, but also open in quality, and proactive in timing. However, no studies have sought to understand what motivates parents to participate in this type of optimal parent-child sex communication, nor assessed these relationships longitudinally. Using Self-Determination Theory (SDT) to inform the analysis, this study investigated parent characteristics (parent's sexual self-concept and parenting dimensions) that may longitudinally predict optimal PCSC. This study further examined whether parental sex communication efficacy mediated these relationships. The sample included 607 mother-child dyads, and the father-figure when available (mother-father-child …

Investigating Bismuth As A Surrogate For Plutonium Electrorefining, Greg Chipman

Theses and Dissertations

Conducting research experiments on plutonium electrorefining is difficult due to the significant hazards and regulations associated with nuclear materials. Finding a surrogate for plutonium electrorefining studies would enable more fundamental research to be conducted. Potential surrogates were identified by determining the physical properties required to conduct electrorefining using a molten metal and molten salt in CaCl2 at 1123 K. More potential surrogates were identified by changing the matrix salt to be a LiCl-KCl-CaCl2 eutectic salt with electrorefining conducted at 673-773 K. Ce-CeCl3, In-InCl3, Zn-ZnCl2, Sn-SnCl2, and Bi-BiCl¬3 were investigated as potential plutonium electrorefining surrogates. Ce electrorefining in molten CaCl2 resulted …

Physics-Guided Modeling Of Acoustic Environments Using Limited Spatio-Spectro-Temporal Data, Mylan Ray Cook Aug 2023

Physics-Guided Modeling Of Acoustic Environments Using Limited Spatio-Spectro-Temporal Data, Mylan Ray Cook

Theses and Dissertations

When creating data-based models it is important to include the underlying physical characteristics and constraints of the data. If physical characteristics are not properly included in the model, results may be infeasible or physically impossible. Acoustic environments are better characterized by ensuring that models include the fundamental spatial, spectral, and temporal characteristics of noise sources, or how they change based on location, frequency, and time. When model data are limited, in availability or in reliability, additional care must be taken to ensure models predict feasible results. This dissertation focuses on physics-guided modeling of acoustic environments using limited data, taking into …

A Step Into Structural Biology: Structural Determination Of Tnk1-Uba And Computational Design Of A Radical Sam Cyclase, Yi-Jie Tseng Aug 2023

A Step Into Structural Biology: Structural Determination Of Tnk1-Uba And Computational Design Of A Radical Sam Cyclase, Yi-Jie Tseng

Theses and Dissertations

Structural biology uncovers life's secrets by studying protein structures via techniques like X-ray crystallography. This knowledge drives advancements in protein engineering for the improvement of human lives. Yet, obtaining high-quality crystals in X-ray crystallography is challenging. To overcome this, we used Translocation ETS Leukemia protein Sterile Alpha Motif domain (TELSAM), a promising polymer-forming crystallization chaperone (PFCC), to enhance protein crystallization. Human thirty-eight-negative kinase-1 (TNK1), a key player in cancer progression, possess a ubiquitin association (UBA) domain that binds polyubiquitin and regulates TNK1 activity and stability. Although sequence analysis hints at an unconventional TNK1 UBA domain architecture, its molecular structure lacks …
