Optimal False Data Injection (Fdi) In Simulated Cooperative Adaptive Cruise Control (Cacc) Systems, Lovro Dukic Jun 2024

Optimal False Data Injection (Fdi) In Simulated Cooperative Adaptive Cruise Control (Cacc) Systems, Lovro Dukic

Master's Theses

In the rapidly advancing field of autonomous vehicles, ensuring the security and reliability of self-driving systems is crucial. Autonomous vehicle systems, such as cooperative adaptive cruise control (CACC), must undergo significant research and testing before their integration into commercial intelligent transportation systems. CACC considers multiple vehicles in close proximity as a single entity, or platoon, with each vehicle equipped with a controller that uses sensor-based measurements and vehicle-to-vehicle (V2V) communication to control inter-vehicle spacing. While this system offers numerous potential benefits for traffic safety and efficiency, it is also susceptible to False Data Injection (FDI) attacks, which can cause the …


Kgscore-Open: Leveraging Knowledge Graph Semantics For Open-Qa Evaluation, Nicholas Hausman Jun 2024

Kgscore-Open: Leveraging Knowledge Graph Semantics For Open-Qa Evaluation, Nicholas Hausman

Master's Theses

Evaluating active Question Answering (QA) systems, as users ask questions outside of the original testing data, has proven to be difficult, due to the difficulty of gauging answer quality without ground truth responses. We propose KGScore-Open, a configurable system capable of scoring questions and answers in Open Domain Question Answering (Open-QA) without ground truth answers present by leveraging DBPedia, a Knowledge Graph (KG) derived from Wikipedia, to score question-answer pairs. The system maps entities from questions and answers to DBPedia nodes, constructs a Knowledge Graph based on these entities, and calculates a relatedness score. Our system is validated on multiple …

What Gives? Trust, Risk, Altruism, And Reciprocity Across 76 Countries, Sherwin Mosavat

Master's Theses

Abstract:

The decades-long literature pertaining to gender-specific preferences lies at the intersection of economics and psychology with a primary focus on the correlation between economic development and gender-specific preferences. Better understanding of this correlation has helped researchers understand how individuals make decisions for their education, finances, and occupation. Falk & Hermle (2018) assess the correlation between GDP and various gender-specific preferences including trust, risk, altruism, and reciprocity. In order to better understand the relationship between economic development and gender-specific preferences, I expand on the Falk & Hermle 2018 framework by introducing new macroeconomic, prosocial, and cultural variables as additional explanatory …


Understanding Parasocial Relationships And The Mental Health Impact, Leslee Lynae Bennett May 2024

Understanding Parasocial Relationships And The Mental Health Impact, Leslee Lynae Bennett

Master's Theses

Parasocial relationships have recently become a topic of discussion in our society. This is because individuals are still looking for something to connect with after the COVID-19 pandemic. These relationships originally were more common among young people, but due to the constant usage of media, individuals have become more attached to popularity which results in an unrealistic online connection. Parasocial relationships are both a fascination and a danger due to the mental connections an individual makes within themselves. This research is a qualitative study of previous research done on parasocial relationships. Topics discussed in this thesis will cover multiple facets …

An Evaluation Of Sonderegger Pine Morphology, Kelsey Denise Shoemaker May 2024

An Evaluation Of Sonderegger Pine Morphology, Kelsey Denise Shoemaker

Master's Theses

Sonderegger pine (Pinus x sondereggeri H.H. Chapm.), the naturally occurring hybrid of longleaf (Pinus palustris Mill.) and loblolly pine (Pinus taeda L.), is considered a producer of poor-quality wood due to observations of stem forking and a high number of large-diameter branches at maturity. Because landowners generally decline planting Sonderegger pine seedlings, nursery workers cull putative hybrids from longleaf pine seedling stock during lifting and processing. However, over the past 100 years, very few studies have quantified stem quality of Sonderegger pine. To gain a better understanding of the early growth and development of Sonderegger pine, evaluations of height, diameter …


Reports Of Autosomal Recessive Disease And Consanguineous Mating Within The Human Population, Johnathon L. Schluter May 2024

Reports Of Autosomal Recessive Disease And Consanguineous Mating Within The Human Population, Johnathon L. Schluter

Master's Theses

It is anecdotally evident when investigating published reports of autosomal recessive disease that a substantial number of cases are the result of related (consanguineous) mating. This research seeks to quantify the percent of manuscripts describing autosomal recessive diseases published between 2000 and 2020 in which consanguineous mating is indicated. We analyzed 602 peer-reviewed manuscripts to identify the percentage of cases presented in which consanguineous mating was indicated, the underlying genes (novel gene or new mutation) and geographical region. These papers were accessed through a specific set of parameters on the free access PubMed Central (PMC) database. A total of 552 …


On The T-Degree Of Anderson Thakur Polynomials In The Case Of Fields Of Order P Where P Is A Prime, Joshua Bush May 2024

On The T-Degree Of Anderson Thakur Polynomials In The Case Of Fields Of Order P Where P Is A Prime, Joshua Bush

Master's Theses

The Anderson Thakur polynomials are of great interest in the investigation of zeta values. Here, we address the question of their degree in finite fields of the form Fp. We define a graph that is closely connected to Anderson Thakur polynomials and which represents a polynomial we denote as Anxn−1. Collections of terms of this polynomial are equating with the vertices of the graph and are vanishing or nonvanishing. The vanishing structure of the graph is analyzed and we conclude with a simple degree formula.


Effect Of Sex On The Accumulation Of Hepatic Mercury In Mallards Wintering In Louisiana, Latorya E. Mason May 2024

Effect Of Sex On The Accumulation Of Hepatic Mercury In Mallards Wintering In Louisiana, Latorya E. Mason

Master's Theses

The increase in mercury production through anthropogenic activities has led to a global crisis of mercury pollution that poses a significant threat to the health of both humans and wildlife. Aquatic ecosystems are especially at risk due to the creation of methylmercury, a toxic form of mercury, by sulfate-reducing bacteria in anoxic sediments and soils. Methylmercury enters the food chain where it bioaccumulates in individual organisms and then biomagnified with increasing trophic level. Aquatic birds are useful bioindicators of many pollutants, including mercury, due to their abundance and position in the food chain. Previous studies have primarily focused on mercury …

Does Trust Influence Being Generous? An Empirical Study Across Five Countries, Andrew Hall May 2024

Does Trust Influence Being Generous? An Empirical Study Across Five Countries, Andrew Hall

Master's Theses

This study examines whether social trust, a key aspect of social capital, influences individual generosity behaviors. Previous research has explored the relationship between social capital and philanthropic actions, but comprehensive analyses remain sparse. To address this gap, we employed a dictator game together with trust-related survey questions, collecting data from participants across five countries globally. We categorized trust into four distinct areas: social trust, ingroup trust, outgroup trust, and general trust. Similarly, we divided our dependent variable, generosity, into two types: costly generous and costless generous behaviors. Our findings were mixed and varied by location. Overall, general trust positively influenced …


Can Aspiration And Financial Literacy Interventions Relieve Internal Constraints? Evidence From Uganda And India, Veronika Divis May 2024

Can Aspiration And Financial Literacy Interventions Relieve Internal Constraints? Evidence From Uganda And India, Veronika Divis

Master's Theses

Can aspiration and financial literacy interventions relieve internal constraints? We address this question through a novel experiment in Uganda and India, using 617 participants in 89 already existing borrowing groups of microfinance institutions. We carry out aspiration and financial literacy treatments as well as a combined treatment group which received both treatments to measure effects on aspirations, hope, agency, and pathway indices. Results show that receiving the aspirations treatment led to 0.34, 0.42, 0.18, and 0.40 standard deviation increases in aspirations, agency, pathways, and aspirational hope, respectively. The game and combined treatment groups also showed positive effects but lacked statistical …


Downregulation Of Dax-1 Expression Via Mirna Overexpression As A Mechanism To Potentiate Breast Cancer, Nicholas C. Devito May 2024

Downregulation Of Dax-1 Expression Via Mirna Overexpression As A Mechanism To Potentiate Breast Cancer, Nicholas C. Devito

Master's Theses

The orphan nuclear receptor DAX-1 (Dosage Sensitive Sex Reversal, Adrenal Hypoplasia Congenita, critical region on the X chromosome, gene 1) plays a key role in mammalian sex determination and steroidogenesis. In addition to these canonical examples, DAX-1 has been shown to play a contradictory role in cancer development. While DAX-1 is overexpressed in lung and prostate cancer, it is downregulated in breast cancer. One of the explanations for the paradoxical role of DAX-1 in cancer development could be microRNA (miRNA) dysregulation. After broadly surveying over 96 miRNAs historically upregulated in MCF7 breast cancer cells, we compared the expression of DAX-1 …


Impact Of Toll-Like Receptor 10 Mutations On Tuberculosis Infections, Adriana Nicole Rafael, Sangman Kim May 2024

Impact Of Toll-Like Receptor 10 Mutations On Tuberculosis Infections, Adriana Nicole Rafael, Sangman Kim

Master's Theses

Tuberculosis (TB), caused by the intracellular pathogen Mycobacterium tuberculosis (M. tb), is a leading global health crisis causing millions of cases and deaths each year. Though it affects individuals of any race, ethnicity, or cultural group, research shows the disease disproportionately affects individuals with Asian ancestry. Immunity to M. tb starts with its recognition by pattern recognition receptors such as Toll-like receptors (TLRs), which are key players in immune responses. TLR-10, an understudied toll-like receptor due to its inability to be studied through mouse models, is thought to play a key role in the clearance of inflammatory diseases. SNP I775V, …

Labors Of Love And Loss: Exploring Relationships In Remitting Latine-American Families, Sequoyah Sv Hilton May 2024

Labors Of Love And Loss: Exploring Relationships In Remitting Latine-American Families, Sequoyah Sv Hilton

Master's Theses

This paper examines the impact remittances have in Latin-American families across borders through qualitative interviews. Remittances, or international transfers of money, are a common support strategy of global migrant communities. There are divergent opinions on remittances, either positioning them as a great potential for developing lower and middle-income countries, or critiquing them as too heavily depended on by states and created as a survival support mechanism by communities to compensate for state neglect. While they are a massive cash flow at the international level, there is a greater need to blend analyses of remittances at the international level at the …
