Pedestrian Evacuation: Vulnerable Group Member Influence On The Group Leaders’ Decision-Making And The Impact On Evacuation Time, Terra Lynne Elzie

Computational Modeling & Simulation Engineering Theses & Dissertations

As pedestrian evacuations of buildings, outdoor venues, and special events occur, dynamic interactions between pedestrians and vehicles during egress are possible. To model pedestrian and vehicle evacuations, simulation models have evolved to incorporate more realistic crowd characteristics and behaviors to provide improved results. Past studies using modeling and simulation, specifically agent-based modeling, have explored pedestrian behaviors such as decision-making, navigation within a virtual environment, group formations, intra-group interactions, inter-group dynamics, crowd behaviors such as queuing and herding, and pedestrianvehicle interactions. These studies have led to relevant insights helpful to improving the accuracy of evacuation times for normal and emergency egress …

Sustainability In Web Development Through Energy Efficiency, Hannah Bebinger

Honors Projects

As global internet usage expands, websites are growing in both size and complexity. Contrary to the common belief that the internet is immaterial and “environmentally friendly”, web pages have significant negative environmental impacts (Frick, 2015). Websites contribute to global greenhouse gas (GHG) emissions and electricity consumption. Considering the current climate crisis, it is crucial that web developers be aware of the impact that their work has on the environment and actively work to improve site energy efficiency. With a lack of regulation and awareness, the environmental impact of websites has remained unchecked despite growing concerns for sustainability. Further research and …

A Discussion On Supplier Selection Modeling Approaches, Sheida Etemadidavan, Andrew J. Collins

Modeling, Simulation and Visualization Student Capstone Conference

Supplier selection is a subfield of supply chain management that involves multiple steps in order for decision-makers to find suitable suppliers. Supplier selection is important as it could influence the whole company positively or negatively. It has, recently, become a topic of interest because of the recent pandemic and its effect on the global supply chain, which causes supply shortages. As such, the focus of this paper is on characteristics of decision-making modeling approaches, specifically agent-based modeling and multi-agent systems, in supplier selection, as its modeling has always been a challenge for companies due to its complex nature.

Representing And Analyzing The Dynamics Of An Agent-Based Adaptive Social Network Model With Partial Integro-Differential Equations, Hiroki Sayama

Northeast Journal of Complex Systems (NEJCS)

We formulated and analyzed a set of partial integro-differential equations that capture the dynamics of our adaptive network model of social fragmentation involving behavioral diversity of agents. Previous results showed that, if the agents’ cultural tolerance levels were diversified, the social network could remain connected while maintaining cultural diversity. Here we converted the original agent-based model into a continuous equation-based one so we can gain more theoretical insight into the model dynamics. We restricted the node states to 1-D continuous values and assumed the network size was very large. As a result, we represented the whole system as a set …

Frequency Of Genetic Variants At The Mc1r Locus In A Student Population, Emmalea K. Dowdy, Grace C. Stubblefield, David K. Peyton

2022 Celebration of Student Scholarship - Poster Presentations

The Melanocortin-1 Receptor gene (MC1R) encodes a protein that is associated with pigmentation in vertebrate animals. An extraordinary number of variations in this gene have arisen over time due to the importance of pigmentation in camouflage, photosensitivity, vitamin D production, and other evolutionary factors. Variations in the MC1R gene sequence became important to survival as humans migrated out of Africa and into cooler climates with less sun exposure, where lighter skin pigmentation (and therefore more vitamin D production) was key to survival. These genetic variations (alleles) continue to exist in modern humans. Recent research into the MC1R gene variations shows …

The true benefit of a PocketQube, CanSat, or femtosatellite is that they can be built with less money, less experience, and less long-term commitment while providing a scaled version of the real-life satellite development process that will engage and inspire students. …

Novel Gain-Of-Function Mutations In The Telomerase Rna Of Saccharomyces Cerevisiae, Keenan Conley, Madison Frazier, Melissa Mefford

2022 Celebration of Student Scholarship - Poster Presentations

Yeast are eukaryotic organisms that contain liner chromosomes. At the ends of these chromosomes, there are special regions known as telomeres. Telomeres are composed of non-coding nucleotides that serve to protect the vital coding DNA found throughout the rest of the chromosome. During the process of DNA replication, however, telomeres become progressively shorter which can lead to cellular senescence. To solve this issue, yeast express the enzyme telomerase. Telomerase is composed of a telomerase reverse transcriptase protein (TERT) and telomerase RNA (TLC1) in yeast. When telomeres become too short, telomerase extends telomeres by adding to the 3’ overhang. Telomeres shorten …

2022 Celebration of Student Scholarship - Poster Presentations

A knowledge gap associated with how fungal communities change in response to climate was identified in the 2018 State of the World Fungi report (Willis, 2018). While it is virtually impossible to test in the present, fungal assemblage changes can be studied in sediments from a warmer-than-present period such as the Miocene Climate Optimum (MCO) (Romero et al. 2021; O’Keefe 2017). The Fungi in a Warmer World project aims to generate and analyze a global-scale data set of fungal biodiversity, ecology, and associated flora from MCO sediments. This dataset will be used to model past fungal assemblage changes across the …

Morphometrics Of The Rare Earwigfly Merope Tuber, Nicholas Finch, Sean O'Keefe

2022 Celebration of Student Scholarship - Poster Presentations

Merope tuber Newman (Mecoptera: Meropeidae) is a rare North American species of earwigfly, which is closely related to common scorpionflies. “Earwigfly” refers to three different species: the Western Australian Austromerope poulton, the South American Austromerope brasiliensis, and finally, the Eastern North American Merope tuber. This last species was the focus of our study. Johnson’s 1995 study was based on 160 earwigflies, where he measured the female abdomen length, male and female forewing length, and male basistylus and dististylus length. In their 2014 study, based on 82 earwigflies, Skvarla, Hartshorn, and Dowling measured head width, pronotum width, forewing length, abdomen length, …

Personal protective equipment (PPE) is used to minimize infection transmission from patient to healthcare worker, or vice versa. During a clinical rotation in a large urban teaching hospital, it was noted that a number of nurses failed to adhere to proper PPE policies. A literature review focusing on thirty-two studies found that average nurse compliance to proper PPE is 34%. This review included an overall discussion of factors affecting compliance, as well as a more in-depth review of the effect of education on PPE compliance, how comfort and proper fitting affects compliance, and the general effectiveness of PPE when used …

“The Never Ending Story:” Circularizing Ch. Viii In Saccharomyces Cerevisiae, Chisom Iloegbunam, Melissa Mefford

2022 Celebration of Student Scholarship - Poster Presentations

Chromosomes are molecules of DNA that hold large quantities of genetic material in an organism. Generally, in nature, eukaryotic chromosomes are linear while prokaryotic chromosomes are circular. Since they are linear, eukaryotic chromosomes possess telomeres, or repetitive nucleotide sequences, on their ends. This significant difference in structure requires different additions to the basic replication process. In prokaryotes, replication starts at a single point on the chromosome and continues until the whole chromosome has been copied. In eukaryotes, replication happens in fragments with multiple starting points. Because of this more complicated replication process, the free 3’ ends of our DNA cannot …

A New Colorimetric Assay Of Apurinic/Apyrimidinic (Abasic) Sites Of Deoxyribonucleic Acid (Dna) Using Bicinchoninic Acid [, Isaiah O. Stephens, Elizabeth M. Thomas

2022 Celebration of Student Scholarship - Poster Presentations

Apurinic/apyrimidinic (AP or abasic) sites are DNA lesions that result from the loss of a nucleobase by hydrolysis of the N-glycosyl bond. It is estimated that AP sites are the most frequent lesions in cells with about 10,000-50,000 times per day per cell under typical aerobic conditions [2]. The formation of AP sites is caused by environmental and cancer therapeutic genotoxins such as alkylating agents, oxidizing agents, ionizing radiation, and ultraviolet radiation.

The Eagle Lake Dam is an iconic part of Morehead State’s campus. It can be seen from much of campus and serves as one of the best views around. It is also the single most important structure on campus. A significant percentage of the campus would be damaged or impaired, as well as many people would be endangered if the dam failed. Hence, I am starting a multi-person and multi-year initiative to monitor Eagle Lake Dam using UAV and remote sensing technology. I hope to have teams make annual 3D models of Eagle Lake Dam over the next several years …

Beetle Diversity Within Ecosystems; Insight Of The Order Coleoptera In The Eastern Kentucky Region, Blake Branham, Hannah Pyles, Charles Lydeard, Sean O'Keefe

2022 Celebration of Student Scholarship - Poster Presentations

Having a multitude of definitions, biodiversity can most commonly be seen as the variety and diversity of life within an ecosystem. Its relevance is crucial for species survival and resource availability; a lack of biodiversity sets an ecosystem up for failure, reducing its productivity, species richness, and increasing organismal vulnerability. Measuring biodiversity is crucial for the understanding of an ecosystem’s health, giving scientists knowledge of its stability, productivity, and persistence. This collected information can be implemented in various ways outside the scientific field as well, such as with policy decisions and legal regulations. Biodiversity is most commonly analyzed through quantitative …
