United States Naval Academy Capstone Day April 24, 2019 1 USNA Capstone Day Sponsors The Capstone Day event was sponsored by: Independent Research and Capstone Project Sponsors Independent Research and Capstone Projects were sponsored by: 2 Welcome from the Academic Dean and Provost Dr. Andrew T. Phillips elcome to the United States Naval Academy’s seventh Annual Capstone Day. Thanks for taking time to join us as we present an academy-wide showcase of senior projects W here in Annapolis. Capstone projects provide students with valuable real-world experience that will help them in their future careers, as military officers and later in private industry. At this year’s Capstone Day you will see the culmination of the year’s academic efforts of our Midshipmen. Today, we have nearly 230 capstone projects and 93 independent research projects that includes 16 Trident projects. These projects represent math, science, engineering, humanities, and the social sciences. In the morning, seniors will present projects in parallel sessions throughout Rickover, Michelson, Chauvenet, Nimitz, Sampson, and Maury Halls. You are encouraged to browse the program and to move from room to room according to your interest. In the afternoon, the same students will re- convene for a poster session in Alumni Hall. I encourage you to take time to engage students in discussions about their work, and please make sure to congratulate them on their impressive ac- complishments in the short time that is their senior year. 3 Table of Contents Schedule of Events 6 Shuttle Bus Schedule 7 Trident Scholar Project Descriptions 8 Morning Presentation Schedules 11 Morning Presentation Descriptions 16 Poster Numbers Listed by Department Abbreviation and Project Title 41 Alumni Hall Poster Map 42 Academic Major Codes Engineering and Weapons Mathematics and Science Humanities and Social Sciences (E&W) (M&S) (HUM/SS) EAS Aeronautical Engineering SCB Biochemistry HEG* English EASA Astronautical Engineering SCH Chemistry HHS* History ECE Computer Engineering SCS Computer Science FLA Arabic EEE Electrical Engineering SIT Information Technology FLC Chinese EGE General Engineering SCY Cyber Operations FPS* Political Science EME Mechanical Engineering SGS General Science FQE* Economics ENR Nuclear Engineering SMA* Mathematics ENM* Naval Arch. & Marine Eng.

Research posters are on display in the lobby of Alumni Hall. Solving the Inverse Problem Using Fixed Random Graph Models Samuel Baker (SMA) The goal of this project is to model real world net- works using random graphs. In this project we de- signed an ideal random graph model and tested it using an original method.

Teachers, Timing, and Tenacity Megan Hanson (SME) This paper studies the effect of soft skills in higher ed- ucation through instructor effects and how personality types affect student performance through six sets of sequential classes. To do this, we look at freshman stu- dents at the United States Naval Academy and analyze instructor effects through a grade distortion model and a value-add model while controlling for a variety of background characteristics and accounting for student personality types as captured by Myers-Briggs. 8 Trident Scholar Research Near Wake Characteristics of a Marine Propeller China's Export Effects: A Multi-Country Analysis in the Presence of Free Stream Turbulence on Global Supply Chains Bennitt Hermsen (EOE) Davis Katakura (SME) This project's goal was to determine the effects of free This project uses bilateral trade flow data covering the stream turbulence on a propeller wake within the first period 1988-2016 at a highly disaggregated product 10 diameters.

Predicting Optimal Maneuvering Time Benefits for Satellite Attitude Control Yash Khatavkar (EASA) The goal of this project is to develop a model to pre- dict the time benefit of using time-optimal satellite atti- tude control rather than eigenaxis maneuvering based on a satellite's moments of inertia. A Parametric Study on Bracing Methods for Asymmetrically Loaded Gridshells Thomas Imhoff (EME) This project focuses on modelling the structural per- formance of large span timber gridshells outfitted with various bracing patterns and subjected to numerous loading schemes. Timber gridshells are traditionally braced to improve their stiffness, stability, and strength, yet no notable research has investigated the impact of specific bracing schemes. As a result, this project seeks to discover how bracing impacts structur- al performance in both symmetric and asymmetric load cases. Numerical simulation of laser induced drop evaporation Stefano Pineda (EME) In maritime environments, laser weapons and laser communications frequently interact with water. Due to these interactions, laser propagation is disturbed through reflection, refraction, and absorption. To un- derstand how lasers are affected when they encounter water drops, an individual drop needs to be examined. Using the fluid dynamics, heat transfer, and geomet- rical optics modules in COMSOL, laser irradiated drops were simulated to determine maximum tempera- tures and vaporization regimes. 9 Trident Scholar Research Coupled Dissipative Jaynes-Cummings Cavities Development of Hybrid Robotic Controller for Au- Dean Rye (SPHH) tonomous, On-Orbit Spacecraft Assembly Appli- cations This project considers a many-body Jaynes-Cummings model where each cavity is coupled to the environment Dakota Wenberg (ERCH) through
