Character Rigging Explorations: Basic Skeleton To Full Simulated Muscle, Lindsay Diana Timbs

Senior Honors Theses and Projects

This thesis project focuses on furthering my knowledge in creating rigs for an organic 3D model with realistic skin deformations. Rigs are the controls used to animate a model. A 3D model's skin deformation is how it squashes and stretches when moved. The project focuses on learning to use simulated muscles, which add the ability to imbue subtle secondary motion to the skin and deliver more realistic deformation as well as the creation of a smooth bind, a standard primary rigging technique. The aim is to compare and contrast their quality based on perceived realism. Subjectively, the muscle simulation was …

What Black Teachers Have To Say About The Push To Remove Critical Race Theory In Schools, Tierra M. Tresvant

Senior Honors Theses and Projects

Critical Race Theory (CRT) and diversity, equity, and inclusion (DEI) in K-12 classrooms have been a contentious issue which has resulted in some U.S. states passing laws that prohibit these topics from being included in classrooms. Literature on critical race theory and the subsequent public policies have shown that professionals in the field of education are under informed about CRT and anti-CRT laws. This research paper explores the opinions of four black 6-12 educators on how DEI and CRT emerge in their classrooms, the implications anti-CRT laws would have on their classrooms, and how their careers would be impacted by …

Music From Rumble Strips: Developing An Experiment For Undergraduates, Hannah Popofski

Senior Honors Theses and Projects

Rumble strips are parallel, evenly spaced grooves that have been ground into pavement, often with a trough-to-trough spacing of 12 inches. They are typically found along the shoulders of limited access highways and are designed to produce steering wheel vibrations to warn drivers that they have drifted off the road. One model for sound production by cars moving across rumble strips is that the fundamental frequency is determined by the number of troughs driven over each second. Assuming 12-inch spacing, the sound produced would have a frequency, in Hertz, that has the same numerical value as the speed of the …

Effect Of External Electromagnetic Stimulation On Microtubule Polymerization, Florian Alushi

Honors Undergraduate Theses

Intracellular processes are influenced by mass transport at different spatial and temporal scales, facilitated by diffusion and stochastic encounters between cellular components. While traditionally explained by short-range "lock and key" interactions, some processes involve rapidly fluctuating charges generating electromagnetic (EM) fields, allowing long-range biomolecular interactions. This challenges the conventional view that efficient biochemical reactions depend solely on random encounters and short-range interactions, suggesting EM fields play a crucial role in cellular dynamics. Microtubules (MTs) are essential components of the cell cytoskeleton, responsible for intracellular transport, cell migration, cell division, etc. Beyond their mechanical role, MTs have unique electromagnetic properties due …

Mapping The Reaction Networks Of Cis Formed In The Ozone-Assisted Oxidation Of C₆ Acyclic And Endocyclic Alkenes, Zachary Clarke

Honors Undergraduate Theses

Criegee intermediates (CIs) are highly reactive species generated during the ozonolysis of alkenes, exerting a critical influence on atmospheric oxidation, combustion chemistry, and synthetic processes. Their reactivity, encompassing unimolecular and bimolecular pathways, shapes oxidation mechanisms and product distributions in these environments. A key determinant of CI behavior is the structural nature of the parent alkene. Acyclic alkenes typically yield intermediates with minimal steric hindrance, facilitating rapid reactions, whereas endocyclic alkenes produce geometrically constrained CIs with enhanced internal stabilization, redirecting reaction pathways and reducing overall reactivity. Despite their importance, mechanistic understanding remains limited due to experimental challenges in detecting CIs and …

Using Wing Flap Sounds To Distinguish Individual Birds, Thinh Phan

Electrical and Computer Engineering

Ornithologist often need to recognize individual birds, but traditional invasive methods, such as capturing, marking, releasing, and recapturing of birds, have limitations. To overcome this, researchers use non-invasive alternatives, such as bird vocalizations. In our study, we used wing flap sounds of three male Zebra Finch birds for individual recognition. We achieved identification accuracies ranging from 55% to 100% by using a combination of Principal Component Analysis-K-Nearest Neighbor (PCA-KNN) and Cross-Correlation method on training data and testing data. PCA-KNN allows for dimensionality reduction and pattern recognition, while the Cross-Correlation method bases data analysis on shifting data elements. Our approach can …

Farm Operator Preferences Regarding Site Specific Weed Control Adoption, Devon Schwarzrock

Agribusiness and Applied Economics

An increasingly popular use for unmanned aerial systems (UAS) is drone applied site specific weed control (SSWC). Site-specific herbicide application allows applicators to target previously mapped weed clusters and spot sprays the targeted weeds individually. This benefits farmers by generating cost savings from reducing herbicide usage and limits overapplication of herbicide. This study aims to identify characteristics of spray drones that are desirable amongst farmers. A discrete choice experiment is used to identify attributes which farmers deem more valuable than others. This study finds that price, herbicide reduction rate, and application rate significantly impact a farmer’s decision to rent or …

International Grain Origin Switching: Contract Washouts And Embedded Switching Options, Caleb Hauck

Agribusiness and Applied Economics

Changing dynamics in the international grain trading industry have led to a rise in two new contracting practices colloquially termed washouts and switching options and formally defined as contract washouts and embedded origin switching options. When spatial arbitrage opportunities exist, grain buying firms switch from one origin to another. This thesis documents the increased frequency with which these contract practices have been used and examines the factors that incentivize firms to use them. Using data from 2018 to 2023, two models are developed with a binomial lattice that value these contracting terms. The results indicate that these practices have significant …

Emotion Regulation Moderates The Prospective Association Between Ern And Anxiety In Early Adolescence: An Age-Specific Moderation Of Cognitive Reappraisal But Not Expressive Suppression, Jaron Xe Yung Tan

Biological Sciences

The increasing prevalence of anxiety problems during adolescence underscores the importance of a better understanding of the development of anxiety. While past research has highlighted a link between error responsivity, indexed by error-related negativity (ERN), and youth anxiety, the role of emotion regulation in the ERN-anxiety relationship remains unclear. We conducted a two-wave study with 115 healthy nine-12-year-olds, and found that expressive suppression (ES), an important emotion regulatory strategy, moderates the ERN-anxiety association. A larger T1 ERN predicted heightened T2 anxiety symptoms in those with higher ES. Interestingly, the moderating effect of cognitive reappraisal (CR), another important emotion regulatory strategy, …
