A Design Science Approach To Investigating Decentralized Identity Technology, Janelle Krupicka
A Design Science Approach To Investigating Decentralized Identity Technology, Janelle Krupicka
Cybersecurity Undergraduate Research Showcase
The internet needs secure forms of identity authentication to function properly, but identity authentication is not a core part of the internet’s architecture. Instead, approaches to identity verification vary, often using centralized stores of identity information that are targets of cyber attacks. Decentralized identity is a secure way to manage identity online that puts users’ identities in their own hands and that has the potential to become a core part of cybersecurity. However, decentralized identity technology is new and continually evolving, which makes implementing this technology in an organizational setting challenging. This paper suggests that, in the future, decentralized identity …

This study will attempt to identify the best soil erosion mitigation methods for Arkansas ornamental landscape settings by comparing the strengths and weaknesses of known techniques. Since soil is not a renewable resource, we must apply conservation practices wherever possible, not just in agricultural settings. To determine the most effective erosion prevention techniques, this study will review soil studies conducted by the NRCS and NASA, as well as articles on best practices observed in ornamental landscape and agricultural industries. These are analyzed by comparing and contrasting techniques against known problems with Arkansas soil to determine which methods are most effective. …
Allylic Rearrangement In Nbs Bromination Reactions, Devann J. Harris, Bryanna L. Wichner
Allylic Rearrangement In Nbs Bromination Reactions, Devann J. Harris, Bryanna L. Wichner
Research & Creative Achievement Day
The allylic bromination of alkenes using N-bromosuccinimide (NBS) is a useful and selective substitution reaction, in which bromine radicals abstract hydrogen from the alkene to form a resonance-stabilized radical intermediate. However, allylic rearrangement can be a consequence of the intermediate's two resonance structures. Some literature sources imply that NBS bromination gives only one major product from asymmetrical alkenes, e.g., 2-hexene and 2-heptene, even when they should form equally stable but non-equivalent resonance contributors. In this research, bromination of trans-2-hexene was performed using cyclohexane as the solvent, and the products were analyzed using GC-MS to determine if only one product, 4-bromo-2-hexene, …

Optimizing Keyboard Layouts For English Text, David Sommerfield
Optimizing Keyboard Layouts For English Text, David Sommerfield
Research & Creative Achievement Day
QWERTY has been the de facto layout for English text input since its invention in 1874. Its continued usage has led to concerns about its ergonomic shortcomings. Previous attempts at layout creation have usually relied on manual observations of typing data rather than a predictive model. To address this issue, we propose a methodology that incorporates both corpus data from 22 million English websites and 8,228 hours of real-world typing data from participants. The corpus data is processed into bigrams and their number of occurrences. The typing data is preprocessed to exclude user-made typos, and then each bigram is tabulated …

Experimental Impact Craters Into Sloped Targets, Ashley L. Miller, Mark Cintala, Christopher Cline
Research & Creative Achievement Day
Impact cratering is a process that shapes every planetary body in our solar system, including the Earth. On smaller planetary objects without atmospheres like the Moon and asteroids (e.g. Vesta and Ceres), impact cratering creates a rough surface with varying topography as opposed to a flat, horizontal surface. In general, impact cratering experiments are performed into flat targets to simplify the physics and model craters at larger planetary scales. However, the smallest craters that form on planetary surfaces are greatly affected by the local topography and cannot be understood by looking at experiments into flat targets. Dr. Anderson and her …
Evaluating Reclaimed Mines And Heavy Metal Soil Contamination, Torin A. Matthews
Evaluating Reclaimed Mines And Heavy Metal Soil Contamination, Torin A. Matthews
ATU Research Symposium
Arkansas has a rich history of lead and zinc mining. While there are still some active mines, many historical mines have been abandoned and/or reclaimed. Although most reclamation procedures result in the burial and containment of target minerals, accessory minerals and elements can be leached out of waste materials/tailings piles and include heavy metals (i.e., Pb, As, Cd). We aim to evaluate the soil and watershed of a few abandoned/reclaimed mines in Pope County, AR, for the presence of heavy metals/source minerals. Soil and stream sediment geochemistry will be conducted using a portable x-ray fluorescence analyzer. Field work and sampling …

Developing An Enzymatic Assay For Wine Analysis, Taylor M. Pagel
Research & Creative Achievement Day
During malolactic fermentation (MLF), malic acid is fermented into lactic acid by the bacteria Oenococcus oeni. During this process, malic acid is then converted into lactic acid, converting sour flavors in the wine to buttery. Here we present an enzymatic method to determine the malate/lactate ratio of wines during MLF. Fresh juice samples had detectable amounts of malate, while wine samples had mixed results, as expected. MLF was initiated in a freshly fermented pre-MLF sample of St. Pepin wine and a decreasing trend of malate over time was detected, as predicted. This was compared to increasing levels of lactate in …
