Aging An Ancient Maya Population From Actuncan, Belize Using Dental X-Rays, Kaitlyn Nicole Cash

Honors Theses

My goal is to determine an accurate age at death estimation of an ancient Maya population from the archaeological site of Actuncan, Belize. This was done by measuring the lengths of the coronal pulp cavities in the individuals’ teeth. I used X-Ray images to measure the coronal pulp cavities of the teeth and estimated age using multiple regression formulae for premolars, molars, and incisors to make age estimations. The formulae came from two studies, Ikeda et al. (1985) and Drusini (2008), that form the basis of my research. Ikeda et al. (1985) was the first to use this aging method, …

The intention of this project is to seek new ways to explore more playable musical instruments in the digital world. The paper presents the software's implementation, challenges such as optimization problems of the synthesizer, and the …

Balancing Data- Vs. Art-Driven Decisions In Video Game Design, Jaden D. Goter

Honors Theses

Video games, like software, need to be designed. Video game development studios tend to use data-driven or art-driven decision-making to design their games. Data-driven decision-making is where active and passive data is collected in order to make informed decisions about the design of a game. Art-driven decision-making is when designers use their artistic intuition to design games, potentially ignoring player data. This paper elaborates on the advantages and disadvantages of both approaches and provides case studies of games designed under both approaches. Based on these studies, for a game to be successful, a combined approach of data- and art-driven decision-making …

"It's Not About The Polar Bears": Evangelical Christian Arguments For Environmentalism, Teresa D. White

Honors Theses

In recent history, white conservative evangelical Christians have formed an influential voting bloc of the Republican party in United States politics. Historically, conservatives have often denied the reality of human-induced climate change and have opposed climate change action and many environmental regulations. However, a number of conservative evangelical Christians have split from their traditionally conservative political views and have accepted the reality of climate change, becoming strong advocates for climate change action. This paper examines the arguments often presented by such advocates. I argue that evangelical environmental advocates craft specific arguments to convince fellow evangelicals to care for the environment …

Convolutional Audio Source Separation Applied To Drum Signal Separation, Marius Orehovschi

Honors Theses

This study examined the task of drum signal separation from full music mixes via both classical methods (Independent Component Analysis) and a combination of Time-Frequency Binary Masking and Convolutional Neural Networks. The results indicate that classical methods relying on predefined computations do not achieve any meaningful results, while convolutional neural networks can achieve imperfect but musically useful results. Furthermore, neural network performance can be improved by data augmentation via transposition – a technique that can only be applied in the context of drum signal separation.

Artificial Reefs: A History, A Science, A Technology, Mairead D. Farrell

Honors Theses

Over the past 60 years, artificial reefs have expanded beyond the definition of a technology, and in turn have developed into a unique branch of marine science. To better emphasize this growth and separation, a brief history of artificial reef development and usage in chapter two shows some of the key shifts over time in this technology’s purpose and the materials used to achieve that goal. Likewise, to indicate the scientific development of artificial reefs as a branch of marine science, their usage for discovery and research is recorded in chapter three, along with the exponential increase in published scientific …

Westbound, Genevieve Nicolow

Honors Theses

Westbound is a twenty-five chapter novella that aims to demonstrate ways in which creative writers can use climate fiction to overcome psychological barriers to act on climate change. The narrative follows Cassie, a character loosely based on a relative of its author, living in a future version of the United States that has been ravaged by climate change and its indirect consequences.

In the novella, Cassie and her mother Nia set out on a cross-country road trip as a climate disaster looms. The narrative explores their relationship and that with Cassie’s estranged father, the implications of projected ecological changes under …

Engagement And Computational Thinking Through Creative Coding, Dana Hoppe

Honors Theses

Rising enrollments in Computer Science pose an opportunity to engage students from diverse backgrounds and interests; and a challenge to deliver on positive learning outcomes. While student engagement is the driving factor for increased learning performance and retention, it has been declining to new lows for Computer Science students in recent years. In order to further explore the potential of contextualized computing as a tool for increasing engagement in computing and developing Computational Thinking aptitude in students, we have developed an introductory computing course contextualized with Art and Design with modules centered around guiding pedagogical principles and aimed at middle …

Contextualizing Sexual Assault Data Collection On College Campuses: A Socio-Technical Approach, Anushikha Sharma

Honors Theses

Sexual assault is a rampant issue on college campuses in the United States. Colleges and universities use a variety of survey instruments to collect data regarding sexual assault as a means to improve campus culture, policies, and resources. These instruments contain a wealth of associated information in the form of metadata, that is, data about data.

This project takes a human-centered socio-technical approach to understanding the data collection processes associated with sexual assault, specifically, on the campus of Bucknell University. By identifying the underlying metadata within the data collection processes, this research contextualizes and critiques the process of data collection, …

Dworkinian Liberalism, The Right To Pornography, And The Internet, Will Nowell

Honors Theses

In a 1981 journal article, “Is There A Right to Pornography?,” Ronald Dworkin argues that we have a right to ethical independence that includes the right to consume pornography. The purpose of this thesis is to inquire as to whether Dworkinian liberalism does entail a right to specifically internet pornography. This research is primarily focused on Ronald Dworkin’s writings in Justice for Hedgehogs, Sovereign Virtue: The Theory and Practice of Equality, and Taking Rights Seriously to describe the principles and character of Dworkinian liberalism and its philosophical relationship to the question of the right to pornography. This thesis considers contemporary …

Accurately Simulating The Battle Of Thermopylae To Analyze "What If" Scenarios, Josh Wasserman

Honors Theses

The Battle of Thermopylae (480 BCE) was a last ditch effort to stall the Persian army as it marched south toward Athens. Led by Leonidas and his personal guard of 300 Spartans, a citizen army of Greeks was able to delay a Persian army of over 100,000 soldiers at the town of Thermopylae for several days. Although the Greeks were ultimately defeated at Thermopylae, the battle provided enough time for the Greek states to regroup and plan a counter attack, eventually defeating the invading Persians. This battle was crucial not only for the preservation of Greek independence, but also the …

Impact Of The Nuclear Phase-Out In Germany: Examining The Costs And Benefits Of Aggresive Energy Policy In Relation To A Sustainable Future, David M. Olio

Honors Theses

The German nuclear phase-out legislation of 2011 will cause substantial changes in the country's energy mix, energy generation and electricity grid demands. The phase-out exists as part of the Energiewende, or energy transition, occurring in Germany where renewable energy has been subsidized to replace the share of nuclear energy, which is decreasing annually and moving towards a complete phase-out in 2022. This paper will analyze the benefits and costs of Germany's decision to phase out nuclear power. First, it will explore the dynamic history of German energy policy and discuss how a history of anti-nuclear sentiments led to the nuclear …

Multi-Agent Simulation Of The Battle Of Ankara, 1402, Ruili Tang

Honors Theses

In 1402, at the north of city Ankara, Turkey, a battle between Ottoman Empire and Tamerlane Empire decided the fate of Europe and Asia. Although historians largely agree on the general battle procedure, the details are still open to dispute. Several factors may have contributed to the Ottoman defeat, such as the overwhelming size of Tamerlanes army, poisoned water, the tactical formations of the military units, and betrayal by the Tartar cavalry in the Ottoman left wing. The approach is divided into two stages: the simulation stage, which provides data to analyze the complex interactions of autonomous agents, and the …

I Remember It Like This: Essays, Robin C. Lewis

Honors Theses

This thesis is composed of eleven personal essays. As an Environmental Policy senior, I wanted to write down some of my formative stories—not just any stories, but those that may reveal the environmental thread in my life, which, I believe, was somehow instilled in me by my parents. This thread has followed me from Texas to Maine, from childhood to almost twenty-three. It has been supported and tested by various characters along the way, sometimes growing faint, other times stronger. As I prepare for something new, I’ve found it valuable to look back on the people and landscapes and stories …

Elliptic Curve Cryptography And Quantum Computing, Emily Alderson

Honors Theses

In the year 2007, a slightly nerdy girl fell in love with all things math. Even though she only was exposed to a small part of the immense field of mathematics, she knew that math would always have a place in her heart. Ten years later, that passion for math is still burning inside. She never thought she would be interested in anything other than strictly mathematics. However, she discovered a love for computer science her sophomore year of college. Now, she is graduating college with a double major in both mathematics and computer science.

This nerdy girl is me. …

Primality Proving Based On Eisenstein Integers, Miaoqing Jia

Honors Theses

According to the Berrizbeitia theorem, a highly efficient method for certifying the primality of an integer N ≡ 1 (mod 3) can be created based on pseudocubes in the ordinary integers Z. In 2010, Williams and Wooding moved this method into the Eisenstein integers Z[ω] and defined a new term, Eisenstein pseudocubes. By using a precomputed table of Eisenstein pseudocubes, they created a new algorithm in this context to prove primality of integers N ≡ 1 (mod 3) in a shorter period of time. We will look at the Eisenstein pseudocubes and analyze how this new algorithm works with the …

Computing The (Un)Computable: A Computationally-Augmented Perspective On The Yasukuni Shrine Controversy, Ryan Muther

Honors Theses

Computational methods have been used with increasing frequency in the social sciences and humanities, due to the availability of digital sources and computing power to study everything from changes in the meanings of words in Latin texts to how knowledge was categorized in eighteen century encyclopedias. Recent trends in the fields of digital humanities and computational social science include statistical methods like machine learning, requiring large pre-tagged and annotated sets of documents which in turn necessitates a great deal of prior work to create data to use with such methods. This reliance on large corpora of annotated data limits the …

Blending Two Automatic Playlist Generation Algorithms, James Curbow

Honors Theses

We blend two existing automatic playlist generation algorithms. One algorithm is built to smoothly transition between a start song and an end song (Start-End). The other infers song similarity based on adjacent occurrences in expertly authored streams (EAS). First, we seek to establish the effectiveness of the Start-End algorithm using the EAS algorithm to determine song similarity, then we propose two playlist generation algorithms of our own: the Unbiased Random Walk (URW) and the Biased Random Walk (BRW). Like the Start-End algorithm, both the URW algorithm and BRW algorithm transition between a start song and an end song; however, issues …

Reading Between The Lines: Verifying Mathematical Language, Tristan Johnson

Honors Theses

A great deal of work has been done on automatically generating automated proofs of formal statements. However, these systems tend to focus on logic-oriented statements and tactics as well as generating proofs in formal language. This project examines proofs written in natural language under a more general scope of mathematics. Furthermore, rather than attempting to generate natural language proofs for the purpose of solving problems, we automatically verify human-written proofs in natural language. To accomplish this, elements of discourse parsing, semantic interpretation, and application of an automated theorem prover are implemented.

Applications Of The Sierpiński Triangle To Musical Composition, Samuel C. Dent

Honors Theses

The present paper builds on the idea of composing music via fractals, specifically the Sierpiński Triangle and the Sierpiński Pedal Triangle. The resulting methods are intended to produce not just a series of random notes, but a series that we think pleases the ear. One method utilizes the iterative process of generating the Sierpiński Triangle and Sierpiński Pedal Triangle via matrix operations by applying this process to a geometric configuration of note names. This technique designs the largest components of the musical work first, then creates subsequent layers where each layer adds more detail.

Audio Software (Vst Plugin) Development With Practical Application, Zachary Hummel

Honors Theses

Audio engineers around the world routinely utilize small pieces of software, known as “plugins,” to help shape the sound of the media they are working with. These plugins are inserted into a digital audio workstation (DAW) and contain digital signal processing (DSP) algorithms that can affect audio in a number of ways limited only by the creativity of the software developer. Common implementations of plugins include equalizers, compressors and limiters, gain, phase rotation or polarity inversion algorithms, reverb and delay, and emulation of the non-linearities of analog audio equipment. The intent of this thesis project is to design and produce …

Making Meyers Clear: An Exploration Of The Chemistry And Art Of Ceramic Glazes, Sara Catherine Williams

Honors Theses

For both seasoned potters and students, looking at a line of unglazed bisque-ware can be a terrifying moment. Terrifying because you know that if you choose the wrong glazes, all of your hard work up until now could be wasted. The form of any clay creation, be it functional or artistic, is equal in importance with the glaze. Bad forms cannot be covered with good glazes, but good forms may be ruined with them. It is through the pairing of the two that a truly beautiful piece is made.

During my undergraduate years and much of my life I have …

Creating Color: Unearthing The Chemistry Of Ceramic Glazes, Jessica Mariah Hargis

Honors Theses

There is something magical about taking lumps of cold clay and turning them into a functional form. The transofrmation process is what first peaked my interest in ceramics. I turned this visual art form my junior year of college after being completely overwhelmed by my chemistry major. Not only did Ceramics 1 teach me basic hand building and surface design techniques, but it allowed me to literally pound out my stress. I've gained a strong adoration for ceramics because it relieves my stress and gives me the opportunity to express myself.

After taking Ceramics 1, enrolling in Ceramics 2 was …

Blooming Lotus, Brian Nguyen

Honors Theses

While reflecting on my poetry chapbook, Blooming Lotus, I ask myself what I was trying to accomplish by creating the chapbook. I have always been interested in my East Asian culture, but growing up as an Asian American has resulted in some ignorance in regards to the topic. I wanted to explore more of my own heritage through the creation of this chapbook by writing poems inspired by East Asian culture. Not only did I want to expose myself to East Asian culture but I also wanted to expose my readers to it as well. Most of my poems required …

La Vie De Blaise Pascal Et Son Heritage Mathématique Et Philosophique, Katherine Weeks

Honors Theses

This paper will discuss the life of Blaise Pascal, his philosophy and mathematics. We will first study the life of Pascal, by looking at his family, the success of his family, and how he was educated. We will then move onto study the history of the arithmetic triangle, which eventually becomes known as Pascal’s Triangle. Finally we will look at Pascal’s Pensées. Finally we will conclude that Pascal is not only known for Pascal’s Triangle but also his legacy in the Philosophic world. It becomes clear that Pascal would not have been the mathematician he was without the philosophy, and …

Cellular Automata And Music: A New Representation, Richard French

Honors Theses

For millenia, we’ve thought of musical composition as a purely human activity. However, we once also thought of an activity like chess to be purely human, but Deep Blue was able to defeat Kasparov in 1995 all the same. Could there perhaps be some tool or algorithm for musical composition that can replicate to some extent what human beings can do with music? This project explores this idea through the use of a tool called a cellular automaton. A cellular automaton is a grid space with a finite number of states for each of the ”cells” or ”squares” where a …
