Rewriting War: Improving The Mlb’S Go-To Advanced Metric, Kolin Atwood

Honors Projects

Traditional Wins Above Replacement (WAR) metrics have long served as a cornerstone of player evaluation in Major League Baseball, offering a context-neutral summary of offensive, defensive, and baserunning contributions. However, this neutrality often overlooks critical factors such as game situation, lineup strength, and advanced baserunning impact. This project proposes an enhanced model, WAR-PC (Wins Above Replacement – Plus Context), that integrates three key improvements: context-dependent batting value (RE24), clutch performance (Win Probability Added, WPA), and Statcast-based baserunning metrics. Using R, player logs, and modern baseball data sources, WAR-PC was calculated for eight players from the 2023 MLB season. The revised …

Unmasking Online Hostility: Analysing And Mitigating Hate Speech In Social Media, Jawaid Ahmed Siddiqui, Siti Sophiayati Yuhaniz, Zulfiqar Ali Memon

Baghdad Science Journal

The social media platforms have been generating an enormous amount of data for every second. Twitter, in practice by the individuals is producing more than six hundred tweets in each second. While freely posting opinions and expressions by users, it is very difficult to confine the hate speech shared against any individual, religion or any ethnic group. Consequently, the persons targeted by such hateful content get frustrated. In this regard the different approaches have been solving this serious problem but, sometimes unable to achieve satisfactory results. Therefore, we propose different Machine Learning models to classify given data in two categories, …

The Impact Of Institutional Features On Student Retention Rates Using Regression And Random Forest Modeling, Grayson Tvrdik

Honors Projects

Student retention is a focus for higher education institutions aiming to improve student outcomes and institutional success. While previous research has often relied on qualitative assessments of college related factors, this project applies quantitative techniques at a national scale. Random forest and beta regression models were used to predict retention rates for public colleges based on institutional characteristics such as financial variables, enrollment patterns, and demographic metrics. The random forest models demonstrated higher accuracy than the beta regression models, leading us to find that financial variables and student integration factors are significant predictors of retention. Beta regression models, though less …

A Survey Of Acoustic Phenomena And Predictive Modeling Techniques For High Explosive Experimentation, Nathanael I. Breed

Senior Honors Theses

High explosive experimentation (HEE) is a technical industry that is regulated, expensive, and dangerous. Developing novel technologies to aid in predictive abilities to minimize the industry’s reliance on the need for full-scale experiments is a worthwhile endeavor. Having the capacity to make accurate predictions regarding the overpressure of a detonation wave after it has interacted with various geometries is useful, but the current state of predictive techniques is limited with many techniques, either neglecting relevant acoustic phenomena or not being able to account for complex geometries. This thesis provides an overview of several acoustic phenomena and the current state of …

Gersberg, Wenling Wang, Xiang Kong, Xin-Rui Xia, Miguel F. Vasquez, Mackenzie King, Goran Bozinovic

Center for Life in Extreme Environments Publications

Nearly all environmental monitoring and research of chemical exposure in the aquatic environment relies on grab sampling of water and/or sediment providing only a snapshot in time. Passive sampling of water provides a more representative estimate of exposure compared to grab sampling, but current passive samplers have a limited working range of chemical properties. We tested a novel Composite Integrative Passive Sampler (CIPS) that simultaneously accumulates both hydrophobic and hydrophilic chemicals in water in the Tijuana River Estuary (TRE) on the U.S.-Mexico border. Quantitative targeted analysis detected 169 of the 193 targeted chemicals, and 128 of them were detected in …

From Clusters To Frameworks: Synthesis, Engineering, And Application Of Sub-2-Nanometer Nanoclusters And Microporous Covalent Organic Frameworks, Melika E Kenari

Chemistry Theses and Dissertations

In this dissertation, we have investigated the complex interplay of atomic composition, structural modifications in covalent organic frameworks (COFs), and atomic-level designs in bimetallic chiral nanoclusters (NCs). By synthesizing COFs and bimetallic NCs, we elucidated how these elements govern their exceptional catalytic, optical, and electronic properties. Our work demonstrates that precise atomic adjustments, tailored pore engineering in COFs, and the strategic use of chiral ligands in NCs enable fine-tuned reactivity and stability. These advancements were applied to enhance photocatalytic performance, optimize iodine adsorption, and facilitate asymmetric A3 coupling reactions, laying a robust foundation for practical applications and future innovations in …

Cascading Effects: Analyzing Project Failure Impact In The Maven Central Ecosystem, Mina Shehata

Quantifying And Characterizing Microplastics In The Greater Philadelphia Region, Emily Lybashev

Biology Honors Papers

Plastic is one of the world's most useful and versatile materials, so it is no wonder that 400 million tons are produced yearly. When exposed to weathering, heat, water, and organisms, plastic degrades and produces microplastics. These microplastics have managed to leach into our oceans, local waterways, bodies, and even our atmosphere. The negative implications of microplastic contamination in our environment are slowly being uncovered with concerns of toxin buildup. Additionally, the amount of microplastics we are exposed to through local waterways is rarely quantified. Though microplastic research is picking up pace, the Schuylkill River which spans the Greater Philadelphia …

Task Demands Influence Search Strategy Selection In Otoconia-Deficient Mice, Ryan M. Yoder, Lucas C. Carstensen, Keshav Jagannathan

Psychology

Introduction: The vestibular system plays a crucial role in visual and non-visual navigation. Our recent study found that signals from the otolith organs are necessary for mice’s use of distal visual cues to guide navigation to an invisible goal. Somewhat surprisingly, however, performance was not significantly impaired on some spatial tasks (e.g., Barnes maze reference memory task), questioning the role of otolith signals in visual navigation.

Methods: We report the results of several additional tests of reference memory performance and search strategy use on two versions of the Barnes maze, in an attempt to establish further understanding of the otolithic …

Lunar Secondary Crater Identification Through Semi-Automated Data Aggregation: The Beginnings Of The Pipeline, Annalyse Dickinson

Physics and Astronomy Honors Papers

Based on the number of primary craters on a surface, one can determine the age of that surface, but secondary craters contaminate that count. No single characteristic can distinguish primaries from secondaries with certainty; a feature that is present in one collection of secondaries can be absent in another due to the multitude of processes involved in their formation and degradation. We aim to develop a pipeline that will classify craters based on characteristics that have been used to differentiate secondaries on the Moon, including elevation profiles, degradation state, radar circular polarization ratio, rock abundance, and spatial clustering. We utilize …

The Chemistry Of Decomposition: The Mechanisms To Decay The Human Body, Lydia J. Buxa

Senior Honors Theses

Taphonomic analysis separates decomposition into four major stages: fresh, early decomposition, advanced decomposition, and skeletonization. It is easy to demarcate the observable changes to the body, but it is far more difficult to know what underlying biochemical processes are occurring. Fresh decomposition begins with algor mortis, livor mortis, and rigor mortis, which sets the stage for the major workforces of decomposition: autolysis and putrefaction. The external signs of decomposition appear in early decomposition, which can be attributed to the breakdown of proteins, lipids, carbohydrates, and nucleic acids. This also leads to major changes in the moisture levels during advanced decomposition, …
