Applications For Functional Data Analysis, Kacy D. Kane

Graduate Research Theses & Dissertations

Functional Data Analysis is often used in the study of data that exists over a continuum, such as time. There are two datasets that will be considered here. For the first study we have a dataset on the efficacy of a lobectomy in reduction or elimination of epileptic seizures in patients. After an initial analysis of the dataset from a multinomial model perspective, we found that there were outliers in our dataset. From there, we considered a Multinomial Mixture Model to aid in the detection of outliers. In our second dataset we are considering a social robotics dataset where the …

Macroeconomic Factors Influencing Foreign Direct Investment In Some Selected Countries In Africa, Richard Essel Mensah

Graduate Research Theses & Dissertations

This paper investigates the possible factors that influence foreign direct investment inflow rate to Africa after controlling for other macroeconomic factors. Using the heterogenous Toeplitz mixed method on a sample of 23 countries from 1998 – 2020, we find evidence of the statistical significance of a relationship between the amount of trade done in Africa and the FDI inflow rate in Africa. We also find a statistical relationship between the labor force participation rate and the FDI inflow rate to Africa. Although the Fixed effect and GLM method did not find the relationship between LFP rate and FDI inflow to …

Shinycore: An R/Shiny Program For Establishing Core Collection Based On Single Nucleotide Polymorphism Data, Steven Kim, Dong Sub Kim, Hana Moyle, Seong Heo

Mathematics and Statistics Faculty Publications and Presentations

Background: Managing and investigating all available genetic resources are challenging. As an alternative, breeders and researchers use core collection—a representative subset of the entire collection. A good core is characterized by high genetic diversity and low repetitiveness. Among the several available software, GenoCore uses a coverage criterion that does not require computationally expensive distance-based metrics.

Results: ShinyCore is a new method to select a core collection through two phases. The first phase uses the coverage criterion to quickly attain a fixed coverage, and the second phase uses a newly devised score (referred to as the rarity score) to further enhance …

Method Development For The Quantification Of Heavy Metals In Biological Matrices And Its Application To Clinical And Environmental Samples, Michelle Catherine Gende

Dissertations

A three-fold approach was taken to develop a method for the detection of heavy metals in different matrices and had to be performed sequentially. The first was to develop a method capable of quantifying lead in complex matrices by graphite furnace atomic absorption (GFAA). The developed method needed to meet specific analytical requirements, namely, to be robust, sensitive, and accurate. Initially, four different sample preparation methods were explored for the quantification of lead using Escherichia coli (E. coli) as a sample matrix. The sample preparation procedures attempted were acidic dilution, matrix modification, conventional heating digestion, and microwave assisted acid digestion …

Reconstructing The Kantian Ends Of Reason: Holiness Analytically Entailing Beatitude In An Eternal Highest Good, Anthony Gudwien

Dissertations

This dissertation argues that an eternal highest good is the final end of sensible, rational agents. This final end occurs in a noumenal world – what I have labelled World Four – that has holiness analytically entailing beatitude. However, before meritorious moral agents are incorporated into this final noumenal world, they will exist in three prior worlds. World One is our current phenomenal world where sensible, rational agents can adopt a maxim to resolutely pursue holiness. World Two, which is made possible by the immortal soul postulate, is where sensible, rational agents continue their resolute pursuit in order to become …

A Scientific Method For International Taxation?, Luiza Leite De Queiroz

Emory International Law Review Recent Developments

Fractioning and fairly distributing parts of a whole is never quite straightforward. Whether we speak of justly portioning and dividing scrambled eggs between siblings or jurisdictional claims over the ocean space between nations, reckoning with the dilemmas of sharing is an integral part of the human experience. Acknowledging that, this essay contends that contemporary discussions on fairness in international taxation ought to be situated within this broader context. It is centrally argued that justly allocating taxing entitlements over cross-border wealth is a task contingent on the same subjective predicaments seen in the division process of any given valuable whole. The …

The Stewardship Mapping and Assessment Project (STEW-MAP) is a national research program developed by the USDA Forest Service that has been implemented at numerous locations in the United States and internationally. This study compared the mission statements of environmental stewardship groups in the Los Angeles River Watershed to previously proposed definitions and frameworks of organizational environmental stewardship to see how well they were reflected. A thematic analysis of the mission statements was also carried out to identify locally important themes …

Educating For Good Thinking: Virtues, Skills, Or Both?, Jason Baehr

Philosophy Faculty Works

This paper explores the relationship between intellectual virtues and critical thinking, both as such and as educational ends worth pursuing. The first half of the paper examines the intersection of intellectual virtue and critical thinking. The second half addresses a recent argument to the effect that educating for intellectual virtues (in contrast to educating for critical thinking) is insufficiently action-guiding and therefore lacks a suitable pedagogy.

Liquid Tab, Nathan Hulet

Williams Honors College, Honors Research Projects

Guitar transcription is a complex task requiring significant time, skill, and musical knowledge to achieve accurate results. Since most music is recorded and processed digitally, it would seem like many tools to digitally analyze and transcribe the audio would be available. However, the problem of automatic transcription presents many more difficulties than are initially evident. There are multiple ways to play a guitar, many diverse styles of playing, and every guitar sounds different. These problems become even more difficult considering the varying qualities of recordings and levels of background noise.

The Future Between Quantum Computing And Cybersecurity, Daniel Dorazio

Williams Honors College, Honors Research Projects

Quantum computing, a novel branch of technology based on quantum theory, processes information in ways beyond the capabilities of classical computers. Traditional computers use binary digits [bits], but quantum computers use quantum binary digits [qubits] that can exist in multiple states simultaneously. Since developing the first two-qubit quantum computer in 1998, the quantum computing field has experienced rapid growth.

Cryptographic algorithms such as RSA and ECC, essential for internet security, rely on the difficulty of complex math problems that classical computers can’t solve. However, the advancement of quantum technology threatens these encryption systems. Algorithms, such as Shor’s, leverage the power …

Defense Of A Small Network, Isabella Adkins

Williams Honors College, Honors Research Projects

A sample network will be virtually created consisting of three routers, one switch, and three hosts. The network will be secured using various methods such as enabling passwords and encryption. After the network has been properly secured, various attacks will be attempted with the goal of breaking into the network. These attacks include reconnaissance (gathering information), penetrating the network using the tool Metasploit, and attempting to get a credential phishing email to end users. If successful in the attacks, the network will be revisited and analyzed for any weaknesses or oversights.
