Description
This thesis project examines the stability margin for different rotor configurations for a quadcopter and compares them against each other to determine the most stable flight configuration possible. The first configuration develops a “standard” for quadcopters with each motor in a corner of a cube at a 60-degree angle from the Y-Axis. The remaining tests increase the angle five degrees per configuration, allowing the motors to get incrementally closer to each other until no longer viable. Five different tests are outlined below depicting the microscopic changes in the pitch and roll of the device. The on-board controller in the quad-copter tracks both the acceleration and gyroscopic movements of the device to obtain the stability margin of each test. Computational analysis is then used to calculate and compare the values found to determine the most stable configuration.

Description
In its totality, “Love and Everything After” consists of five tracks. In musical circles, this is considered an EP (extended play), a collection of music longer than one song but generally more brief than a full album. Each track combines varying degrees of my own acoustic and piano instrumentation with modern production elements, all tied together with a corrected vocal and a quick mix and master by my producer who doubles as my sound engineer for this project. I will outline my experience with the creative process here as well as break down the development of each song. A fair bit of the lyrical composition is dedicated to background information that may seem to verge on oversharing, but alas, I am a writer. I consider verging on oversharing an inevitable cog in any successful songwriting operation. I’ve decided to tackle the songs in chronological order, prioritizing the time during which the bulk of the piece was first assembled.

Description
Musculoskeletal heterogenous tissues are crucial for dissipating mechanical load during physical activity. Modern procedures to repair these tissues have proven inadequate to restore full functionality, thus there is a need for alternative reconstructive methods. Consequently, tissue engineered scaffolds can mimic the native structure of tissues and trigger a healing response. Heterogenous tissues like the tendon-bone junction consist of an interdigitated fiber alignment gradient from the tendon to the bone. It has been shown that electrospun fiber alignment gradients can be fabricated from the incorporation of magnetic fields. In this study, manipulating electrostatic and magnetic interactions from various electrospinning collector arrangements were investigated for creating an interdigitated fiber alignment gradient. The collector arrangement consisting of a magnet overlaid with razor cut aluminum foil proved to provide increased control over the interfacial shape. The rapid transition at the interfacial region was verified with brightfield microscopy revealing an interdigitated gradient from highly aligned fibers to unaligned fibers.

Description
Despite efforts to recruit and retain female engineering students, only about 21.3% of bachelor’s degrees each year in engineering and computer science are awarded to women. The purpose of this synthesis is to understand the ways in which current research has explored how self-identity, engineering identity, and sense of belonging influence undergraduate women’s persistence. Analysis is focused around 4 themes that emerged: (1) Sense of Self: Self-Efficacy, Expectancy Value Theory; (2) Culture of Engineering: Engineering Identity; (3) Stereotype Threat; (4) Interdisciplinary Studies to Expand the Culture of Engineering. Conclusions of this synthesis may be used as opportunities for future engagement with these topics.

Description
Plant viral vectors have previously been used to produce high expression levels of antibodies and other proteins of interest. By utilizing a transformed Agrobacterium with the vector containing the protein of interest for infiltration, viral vectors can easily reach the plant cells making it an effective form of transient protein expression. For this project two different plant viral vectors were compared; the geminiviral vector derived from Bean yellow dwarf virus (BeYDV) and the MagnICON vector system derived from Tobacco Mosaic Virus(TMV) and Potato Virus X(PVX). E16, an antibody against West Nile virus, has previously been expressed using both systems but expression levels between the systems were not directly compared. Agrobacterium tumefaciens EHA105 cells were transformed with both systems and expression levels of E16 were quantified using ELISAs. Results showed very low expression levels of E16 using the geminiviral vector indicating a need for further investigation into the clone used as previous studies reported much higher expression levels with the system.

Description
This study explores the relationship between three physics-based predictive models defined by Castruccio et al. (2013), and four different distinct experimental morphologies of lava flows produced in a series of laboratory simulations where polyethylene glycol 600 (PEG) was pumped into an inclined chilled bath of water. The length of the experimental flow was recorded over time to create an experimental model to later be compared to the physics-based predictive models. The experimental morphologies are pillowed, rifted, folded, and leveed flows which can be characterized by a dimensionless parameter 𝛹, which scales natural lava flows to experimental lava flows and is a ratio of timescales, the characteristic timescale of thermal flux from the vent and the characteristic timescale of crust formation caused by surface cooling (Fink and Griffiths 1990). The three physics-based models are presented such that the downslope gravitational acceleration drives the flow, while either the Newtonian viscosity of the flow, the Yield Strength of the core (YS), or the Yield Strength of the growing crust (YSC) is the primary retarding factor in flow propagation. This study concluded that low 𝛹-value flows (low flux, low temperature, extensive crust formation) are better captured by the YSC model. And although the Newtonian model did not perfectly capture the behavior of any experimental flows in this study, high 𝛹-value flows (high flux, high temperature, little crust formation) that formed levees exhibited the most Newtonian behavior.

Description
It is widely accepted that mentorship between people of similar backgrounds and slightly different ages is a mutually beneficial partnership (e.g., Angelique, Kyle, & Taylor, 2002; Yomtov, 2017). Mentoring relationships exist in many forms across the education spectrum, from middle school students interacting with their younger peers to the popular “Big-Little system” adopted by fraternity and sorority groups in U.S. colleges and universities, and beyond educational settings throughout the working world. However, one place where mentoring has received relatively less attention, from researchers as well as from practitioners, is in undergraduate student leadership-focused organizations at the college level.

Description
The goal of this product was to create a highly customizable application in which any individual, musician or not, can create a harmony for the user’s melody. This Automating Music Composer is built on the underlying rules of music composition, rules that are unique for each type of music available. This program is built on rules that are similar to how a Finite State Machine works (Fig 1). Each state represents a different chord in a given key, where the first roman numeral represents the first note in the chord progression. Each transition represents the action that can be taken by the chord progression, or the next note that can be reached by the current note. The user is able to manipulate these rules and styles, adjust different musical parameters to their liking, and is able to input their own melody, which then will output a unique harmony. This product aims to bridge the gap between predictive technologies and musical composition. Allowing the user to be more involved in the composition process helps the program to act as a tool for the user, rather than a separate entity that simply gives the user a completed recording. This allows the user to appreciate and understand what they are helping to produce more than they would if they were to simply be an inactive consumer of a random music composer. This product is meant to feel like an extension of the user, rather than a separate tool.

Description
The process of cooking a turkey is a yearly task that families undertake in order to deliver a delicious centerpiece to a Thanksgiving meal. While other dishes accompany and comprise the traditional Thanksgiving supper, focusing on creating a turkey that satisfies the tastes of all guests is difficult, as preferences vary. Over the years, many cooking methods and preparation variations have come to light. This thesis studies these cooking methods and preparation variations, as well as the effects on the crispiness of the skin, the juiciness of the meat, the tenderness of the meat, and the overall taste, to simplify the choices that home cooks have to prepare a turkey that best fits their tastes. Testing and evaluation reveal that among deep-frying, grilling, and oven roasting turkey, a number of preparation variations show statistically significant changes relative to a lack of these preparation variations. For crispiness, fried turkeys are statistically superior, scoring about 1.5 points higher than other cooking methods on a 5 point scale. For juiciness, the best preparation variation was using an oven bag, with the oven roasted turkey scoring about 4.5 points on a 5 point scale. For tenderness, multiple methods are excellent, with the best three preparation variations in order being spatchcocking, brining, and using an oven bag, each of these preparation variations are just under a 4 out of 5. Finally, testing reaffirms that judges tend to have different subjective tastes, with some having different perceptions and opinions on some criteria, while statistically agreeing on others: there was 67% agreement among judges on crispiness and tenderness, while there was only 17% agreement on juiciness. Evaluation of these cooking methods, as well as their respective preparation variations, addresses the question of which methods are worthwhile endeavors for cooks.
