Utilizing Computer Modeling To Optimize Electric Fields Within Xenon Time Projection Chambers, Miles Meloni

Honors Theses

XENONnT is a physics experiment designed with the goal of detecting dark matter particles. The detector is a time projection chamber; a series of charged electrodes creates an electric field, surrounding a central body filled with liquid and gaseous xenon. Photomultiplier tubes (PMTs), positioned on either end of the chamber, serve to detect light signals. We seek to minimize the root mean square of the electric field norms experienced by the PMTs. This quantity corresponds to the variance in the electric field observed by the PMTs. Establishing a consistent electric field is important to maintaining these sensitive components. The electric …

Inequality In The Urban Forest: Modeling Tree Canopy Dynamics Through Demographics And Restoration Strategies, Eve Johansson

Honors Theses

Urban tree canopies play an important role in environmental quality, public health, and neighborhood livability, yet their distribution is highly uneven and often reflects historical patterns of inequality. In Brooklyn, long-term processes such as redlining, uneven development, and demographic change have contributed to persistent disparities in access to green space.

This thesis examines how urban tree canopy evolves across space and time in Brooklyn and how different restoration strategies affect long-run outcomes. The analysis uses demographic and canopy data from 1990-2020, considering race, income, employment, and educational attainment. Among these, education is the most consistent predictor of canopy coverage, with …

A Web-Based Wizard-Of-Oz Platform For Collaborative And Reproducible Human-Robot Interaction Research, Sean O'Connor

Honors Theses

The Wizard-of-Oz (WoZ) technique is widely used in Human-Robot Interaction (HRI) research, but two persistent problems limit its effectiveness: existing tools impose technical barriers that exclude non-engineering domain experts (the Accessibility Problem), and the fragmented landscape of robot-specific implementations makes interaction scripts difficult to port across platforms (the Reproducibility Problem- concerning execution consistency and portability, not third-party replication). Through a literature review, I identified three design principles to address both: a hierarchical specification model, an event-driven execution model, and a plugin architecture that decouples experiment logic from robot-specific implementations. I realized these principles in HRIStudio, an open-source, web-based platform providing …

The Discrepancies In Voter Perception Of Male And Female Political Candidates: Biases Of Characteristic Traits And Policy Priority, Julia Piver

Honors Theses

Gender remains a defining factor in how political candidates are perceived by the American electorate, shaping not only evaluations of characteristic traits but also perceived policy priority. These discrepancies are rooted and propelled by traditional gender roles from the 1900s. This thesis shows that the perceptions of female and male political candidates differ depending on the informational environment as well as the voter demographics. I used both a quantitative nationally representative survey and a qualitative interview of students on Bucknell's campus. The date revealed that individuals in lower information environments are more likely to enact gender stereotypes along traditional gender …

Quantitative Assessment Of Roasted Coffee Freshness Over Time Using Multi-Parameter Analysis, Maya Fetzer

Honors Theses

Roasted coffee undergoes continuous chemical and physical degradation after roasting, yet industry freshness standards remain empirically defined rather than grounded in measurable parameters. This study developed a multi-parameter framework for quantifying roasted coffee freshness by integrating gas-phase and solid-phase analysis, backed by human sensory evaluation, across three roast levels — light (City+), medium (Full City), and dark (Vienna) — over a four-month storage period. CO2 off-gassing was monitored continuously for 30 day, gas chromatography-mass spectrometry (GC-MS) tracked volatile compound changes in headspace gas, and Fourier transform infrared-diffuse reflectance spectroscopy (FTIR-DRIFTS) quantified oxidation-associated functional group changes, and microindentation assessed bean stiffness. …

Barriers To Immunity: Understanding Covid-19 Vaccine Uptake In Africa, Emilia Blechschmidt

Honors Theses

This thesis examines the factors influencing COVID-19 vaccine uptake across African countries, with a focus on structural, informational, and behavioral barriers to immunization. Drawing on cross-country data, the study analyzes how access to transportation, reliable information, and healthcare resources shape vaccination rates, alongside the effect of demographics and institutional factors in shaping individual perceptions of risk and vaccine safety.

The findings emphasize that the broader strength and preparedness of national health systems strongly influence vaccine uptake. Countries that demonstrated higher coverage of routine childhood immunizations, such as polio and hepatitis B, also tended to perform better in COVID-19 uptake efficiency …

Combining Haptic Feedback With Electromyography To Study Knee Injury In Stationary Cycling, Christopher Kirby

Honors Theses

Patellofemoral Pain Syndrome (PFPS) is the most prevalent overuse injury in cycling, often linked to altered neuromuscular activation patterns of the quadriceps and hamstrings. While sensory feedback has successfully modified cyclists posture, there is a critical lack of evidence-based interventions targeting the underlying muscle activation imbalances associated with chronic knee pain. This study aimed to develop and validate a novel, real-time biofeedback system that utilizes electromyography (EMG) to trigger vibrotactile cues, aiming to shift muscle onset timing earlier in the pedal stroke to mitigate PFPS-related imbalances. A closed-loop system was engineered by integrating a Delsys EMG system with a SageMotion …

Design And Analysis Of Energy Recovery Methods For Reduced Aircraft Emissions, Joshua C. Hauck

Honors Theses

Aircraft flights are an increasingly popular mode of transportation. However, their harmful impacts on the environment are a growing concern. Many engineers have worked to develop fully electric aircraft to address this issue. Although they are much more sustainable than conventional aircraft, electric aircraft encounter severe limitations imposed by current battery technology. One alternative route engineers have taken is developing energy recovery methods (ERMs). These are marketed as devices that reduce aircraft fuel consumption without significantly changing their structure and functionality, making them an excellent short-term solution. However, there is little to no consideration of the tradeoffs induced by the …

Group-Based Integer Factorization: Theory And Performance, Phuong Cao

Honors Theses

Integer factorization, the problem of finding a nontrivial factor of a composite integer N=pq for large primes p,q, particularly at the size of RSA moduli, is a notoriously difficult challenge that takes classical methods such as Trial Division and Fermat’s Algorithm trillions of years to solve. This thesis studies four probabilistic algorithms that exploit algebraic group structures to achieve significantly better, subexponential efficiency for certain classes of N: Pollard’s p-1, Williams’ p+1, Lenstra’s Elliptic Curve Method, and Pell’s Conic Method. In each case, the algorithm operates on a group over ℤ/Nℤ that decomposes, via the Chinese Remainder Theorem, into corresponding …

Paleoflood Chronology For The West Branch Of The Susquehanna River Using Abandoned Chute Channel Sediments, Pennsylvania, Usa, Juliette A. Vanluven

Honors Theses

Anthropogenic climate change is altering the hydrologic cycle, increasing flood frequency and severity, with associated increased risks in population exposure. This is associated with increasing risks to the population of the Susquehanna River Valley, which supports over 600,000 people today. However, our understanding of the frequencies of large floods is limited by relatively short instrumental records. By studying sediments from an abandoned chute channel in the Robert Allen Natural Area near Williamsport, PA, we can extend the existing flood records using paleoflood slackwater sediments along the West Branch of the Susquehanna River.  Sylvan Dell is an abandoned chute channel that …

Assessing Relations Between Rape Myth Acceptance, Prior Sexual Victimization, And Bystander Intervention Behavior, Zoe Mendel

Honors Theses

Campus Sexual Assault (CSA) remains a very prevalent issue in higher education (Koss et al., 2022). Through cultural norms, sexual violence is often normalized, with blame frequently shifted away from perpetrators and onto victims. Rape myth acceptance (RMA) contributes to harmful harmful attitudes that justify or minimize sexual violence (Lonsway & Fitzgerald, 1994). Prior research suggests that lower endorsement of rape myths is associated with greater prosocial bystander intervention behavior (McMahon, 2010); however, findings on the role of prior victimization are mixed. This study used a mix-method approach, including a survey and interviews. Results indicated that members of Greek life …

Sedimentological Characterization Of Main And Chute Channel Scroll Bars Along The Kantishna River, Alaska, Cooper Sentz

Honors Theses

Scroll bars, arcuate sediment ridges found along the inner banks of river bends, are common floodplain features in meandering river systems that form during lateral channel migration. Two hypothesized formation mechanisms described in prior studies are the aggradation of suspended load onto abandoned inner bank levee (IBL) deposits during overbank flow and the migration of transverse bar packages from the channel bed up onto the point bar during flooding events. To study the sedimentology and geometry of these features, we conduct remote sensing and field analysis on a 60 km portion of the Kantishna River, AK: a highly sinuous, pro-glacial …

Constitutional Structures In Private Law And The Example Of Waste Law, Jill M. Fraley

Scholarly Articles

This Article proposes three criteria for when a private law mechanism performs a structural constitutional function: when it constrains present authority in the name of future stability, when it disperses enforcement to avoid centralized authority, and when it has structural entrenchment to avoid ordinary displacement. While many private law doctrines contain constitutional resonances or echo rights, the core of constitutional law is the power structure—a precondition for the protection of those rights. Constitutional structures have three key components: self-binding through time, separation and diffusion of power, and entrenchment beyond ordinary politics. For a private law doctrine to do more than …

A Study Of Adaptive Reuse Of A Decommissioned Golf Course Through A Nature-Based Approach: Woodhaven Golf Course, Fort Wort Texas., Justin B. Watson Mr.

Landscape Architecture Masters & Design Theses

Across the nation, golf courses are shutting down due to a lack of demand. Golf course developments began in the United States in the early 1950s During that era, demand for golf courses and housing was high. As golf’s popularity grew, developers saw golf courses in developments as high value-add amenities (Grooms, 2010). During the late 1990s and early 2000s, developers across the country raced to construct as many golf course communities as they could even as the number of golfers leveled out (Downey,2011).

Decommissioned golf courses across Texas are being underutilized as potential amenities for both the local community …

Unchanging Gospel Message, Changing Context: Contextualization Strategies In The Lukan Paul, Irenaeus, And Athanasius, Joy Axelsson

MA in Religion Theses

This thesis examines how early Christian leaders strategically contextualized the gospel within the diverse sociohistorical contexts of the Roman Empire while maintaining theological consistency. Using a comparative synchronic methodology adapted from Michael Gorman, it analyzes five primary texts spanning the first through fourth centuries: the Lukan Paul’s missionary speeches in Acts (Pisidian Antioch, Lystra, and Athens), Irenaeus’s On the Apostolic Preaching, and Athanasius’s On the Incarnation. Each text is analyzed within its literary, historical, and cultural context to identify patterns of strategic constants and variables in gospel presentation. The analysis shows that central gospel elements, such as Christology, monotheism, …

Buckling Analysis Of Auxetic Composite Laminates And Optimal Design Using Lamination Parameters And Machine Learning, Hans Bendon Maria Tamil Selvan

Mechanical and Aerospace Engineering Theses

Composite materials are widely used as structural panels in aerospace, automotive, and civil engineering applications, where buckling is often a critical failure mode. This thesis focuses on the analysis and design of composite laminates that maximize buckling performance under prescribed stiffness and thickness constraints.

The first part of the study investigates the buckling behavior of auxetic laminates, which exhibit a negative Poisson's ratio. While previous studies suggest that auxetic laminates can achieve higher critical buckling loads than non-auxetic laminates under simply supported boundary conditions with lateral restraint, the influence of other boundary conditions and plate aspect ratios has not been …
