A Part of Me: The Value Division I Student-Athletes Place on Their Student-Athlete Identities and its Implications for Transition Out of Sport
Alyson McAdams
Division I collegiate student-athletes often struggle with transitioning out of sport due to the value and salience placed on their student-athlete identities. This study was approached using a constructivist worldview and narrative methodology in which the data relied on the student-athlete participants sharing their views and experiences. Four male and four female Division I collegiate student-athletes within their final year of athletic participation at the University of Dayton partook in a qualitative focus group about their student-athlete identities. The findings reflect that anticipating the end of a collegiate athletic career allows student-athletes to begin to understand who they are outside of their sport despite their current priorities and responsibilities revolving around their sport. While the thought of transitioning out of sport is overall very sad, scary, and uncertain, the findings reflected that the transferable skills and lessons gained from a Division I collegiate student-athlete experience will benefit their future careers and ability to positively impact others. Implications for practice involves intentionally encouraging student-athletes to discover their interests and sense of self outside of their sport in order to make the transition out of being a student-athlete easier and more manageable.

Application of Pressure Sensitive Paint at the University of Dayton: Small Rotorcraft Applications
Jacob Kulig
Traditional measurement of pressure on wind tunnel models requires individual pressure transducers or other discreet sensors. When considering a large area or complex geometry, placing an adequate number of sensors can be cost prohibitive and physically challenging. Computational fluid dynamics (CFD) provides an alternate approach to such experiments, but often needs experimental verification. Pressure-sensitive paint (PSP) is a distinctive, appealing technique for providing pressure measurements in these cases. By measuring the intensity of a specialized paint’s luminescence, the pressure at almost all visible points on a test object can be found. In some unsteady aerodynamic cases, the paint mixture is altered to provide faster response times, thus allowing rapidly changing phenomena to be analyzed. This technique has been utilized for several decades; however, it is heretofore unused at the University of Dayton. This research provides the groundwork for the use of PSP in various applications at this university. The technique is then applied to analyze the ground effects of small rotorcraft blades. This will assist in revealing the underlying characteristics of the unsteady flow that occurs between a small propeller and the ground, as may occur in unmanned aerial vehicles.

Applications of Calculus of Variations: Finding Optimal Solutions to Boundary Value Problems in Navigation, Mechanics, and Nature
Ethan Shade
Calculus of variations is a branch of mathematics that deals with the optimization of functionals, which are functions that assign a scalar value to an input function. A functional could be a measurement of quantities such as time, cost, or energy, while also under boundary value constraints such as physical limitations. To find optimal functions of the functional, one uses the Euler-Lagrange equation to derive a solution function and verifies it satisfies the Legendre condition to prove the solution is the optimal one. To illustrate the applicability and effectiveness of the technique, this project investigates multiple boundary value problems, such as the quickest path to cross a moving river, the maximum deflection of materials under stress, and deriving (naturally occurring) optimal curves. These examples demonstrate how calculus of variations can be used to both solve for optimal solutions and derive the equations that are already represented in physical systems.

Approximate Motion Synthesis of Four-Bar Linkages Using Poles: A Bi-Invariant Approach
Tianze Xu
This research presents a novel approach to the synthesis of planar four-bar mechanisms for rigid-body guidance by optimizing the location of the displacement poles. Traditional methods often rely on incompatible measures, leading to suboptimal solutions. In contrast, the proposed technique focuses solely on the displacement poles, which can be described by their location and can be used to define a bi-invariant metric, resulting in a robust optimization process. Moreover, the method reduces the optimization size by utilizing a technique that does not require the entire set of displacement poles. The effectiveness of the approach is illustrated through several examples and compared to established methods. The proposed method has the potential to reformulate and simplify approximate motion synthesis problems for low DOF machines, such as metamachines, by using the planar four-bar as an approximate solution.

A Preclinical Model to Study the Relationship Between Alcohol Intake and Voluntary Exercise in Females
Corey Deel; other authors: Samuel Fisher (co-first author) and Tracy R. Griggs
Alcohol-use disorders are becoming increasingly prevalent in females, highlighting a need to better understand the relationship between alcohol (ethanol) and other reinforcers, such as voluntary exercise. Preclinical research utilizing male rodents to explore ethanol use and behavior has been the standard, despite documented differences between males and females. Studies have indicated that females run and drink more than males when given access to voluntary wheel running and ethanol. Previous studies in our lab have used male rats to explore the concept of hedonic substitution, which is the replacement of one reinforcer with another, by giving access to voluntary exercise for some time before removing and replacing it with access to ethanol solution (Lynch et al., 2019). However, for this study, we expanded our experimental design to study the relationship between ethanol and voluntary exercise (running) in females. Our current experiment consisted of one group of runners (n=10) with concurrent access to voluntary wheel running and ethanol compared to a group of non-runners (n=10) with access to ethanol. We measured ethanol consumption and preference at 30min and 24hrs, running distance (m) and time spent (min) running. The experiment is ongoing, and to-date we have not observed differences in ethanol measures between our runners and non-runners. We will perform measures of anxiety-like behavior at the experiment’s conclusion.

Arduino-based laser light security system with alarm
Venkata Sai Neeraj Viswa Konathala
This project shows an Arduino-powered laser light security system with an alarm. The device uses the laser beams to identify any trespassing into a certain area. The alarm system is managed by the Arduino microcontroller. Two laser modules, two photoresistors, a buzzer, and an Arduino board make up the system. The two opposing edges of the space that needs to be secured are where the laser modules are situated. Between the laser modules, the photoresistors are positioned, and they are used to detect any breaks in the laser beam. The photoresistor notices an interruption in the laser beam and alerts the Arduino board when it happens. To notify the user of the incursion, the Arduino board in turn turns on the buzzer. An effective and secure way to identify intrusions is provided by the system. It is affordable and simple to setup and utilize the system.

Arduino Based Radar System
Srikar Janga
Radio waves are used by RADAR, an object-detection system, to calculate an object's range, altitude, direction, and speed. There are many various sizes and performance requirements for radar systems. Airports utilize a variety of radar systems for air traffic management, long-range monitoring, and early warning systems. The brains of a missile guidance system are radar systems. There are small portable radar systems that a single person can maintain and run as well as systems that take up many sizable rooms.Several governments developed radar in secret both before and during World War II. The United States Navy came up with the name RADAR, not the actual technology, in 1940 to stand for Radio Detection and Ranging. Since becoming a common noun in English and other languages, radar has lost all capitalization.The modern uses of radar are highly diverse, including:•Air traffic control•Radar astronomy•Air-defense systemsDigital signal processing is used in high-tech radar systems, which can extract meaningful information from extremely loud noise.The Air Force, Navy, and Army all use this technology. Such technology is currently being used in Google's future Prius and Lexus autonomous cars as well as the self-parking car systems introduced by Audi, Ford, and others. The project we created can be used by the customer in whatever systems they choose, such those in a car, a bicycle, or anything else. The project's use of Arduino gives the module's usage even more freedom to be used as needed.

A Review of the Detection of Gravitational Waves by Laser Interferometers
Liam Horst
The theory of general relativity published by Albert Einstein in 1915 predicts that accelerating massesemit gravitational waves. The effects of these passing gravitational waves are exceedingly weak and verydifficult to detect. The first detection of gravitational waves was made in 2015 by the LaserInterferometer Gravitational-wave Observatory (LIGO). The first detected gravitational waves, emittedfrom the merger of two black holes, changed the length of the arms of the interferometer by much lessthan the diameter of a proton. Gravitational waves provide a very different window into the universethan do electromagnetic waves. Electromagnetic waves, unlike gravitational waves, are emitted only bycharged objects, are trapped by black holes, and may be distorted or blocked as they travel to the earth.Gravitational-wave detection provides unique information about the most energetic events in theuniverse such as colliding black holes and exploding stars. This information could significantly deepenunderstanding of the large-scale structure of the universe. This project reviews the theory behind thepropagation of gravitational waves and their detection by ultra-sensitive laser interferometers. Newinsights into the nature of the cosmos that might be provided by detection of gravitational waves will be summarized.

A Sibling Comparison Study Exploring Effects of Parenting on Self-Esteem in Adolescents
Molly Griffin
Prior research has suggested a link between self-esteem in children and adolescentsand the parenting styles and behaviors of their parents. Research has identified dimensions ofwarmth, control, autonomy support, trust, flexibility, and demandingness as potential variablesexplaining this relationship. Existing literature has been limited by confounding variables suchas genetic influences, home environment, race, culture, and socioeconomic status, as well as by alack of longitudinal data. The current study uses a sibling comparison design to control for theinfluence of these genetic and environmental variables and allow for a more accurate estimate ofthe link between parenting and self-esteem. It uses data from the Children of the NationalLongitudinal Survey of Youths (CNLSY) which includes 11,545 biological offspring of womenin the previously collected data set, the National Longitudinal Survey of Youth, 1979 (NLSY79).The data on parenting styles and behaviors was taken from three domains of the CNLSY: theshort form HOME survey, a report of engagement, and a survey of perceptions of autonomy,disharmony, and intimacy. Self-esteem was measured using the Rosenberg Self-Esteem Scale. Asignificant association was found between intimacy and self-esteem scores in the populationestimate; however, this association was not significant in the sibling-comparison model. Resultssuggest that links between self-esteem and parenting behaviors are confounded by backgroundvariables within families.

Assistive Communication Device Technology: Ethics and Possibilities in Therapy with Non-Speaking Clients
Amanda Bursch
Music therapy is a healthcare field wherein music experiences and the myriad relationships formed between client(s), board-certified music therapist(s), and music activates health-oriented changes (Bruscia, 2014). Within this field there are multiple facets that directly impact the client’s experiences; these include: arrangement of the therapy environment, role and function of music experiences, therapeutic relationships, and communication in verbal and non-verbal forms. However, there is a gap in the education and training of music therapists concerning alternatives to verbal communication, and the use of these alternatives in therapy. Through interviews and analysis, this thesis presents findings regarding the experiences of one non-speaking music therapy participant, and three board certified music therapists with relevant expertise, to empower current and student music therapists to advance their engagement with non-speaking clients in music therapy.

Automatic car parking system
Supriya Kayathi
A smart parking solution that can autonomously park and retrieve cars without the need for human interaction is the automatic car parking system using Arduino and ultrasonic sensor. The device employs an ultrasonic sensor and an Arduino microcontroller board to detect the presence of an automobile and direct it to a predetermined parking location.The project requires basic understanding of electronics and programming, as well as components such as Arduino Uno or similar microcontroller board, ultrasonic sensors (HC-SR04), LCD screen, LED lights and arrows, motors and gears, power supply, breadboard and jumper wires.The system uses a series of ultrasonic sensors installed in the parking lot that are connected to the Arduino board. When a car enters the parking lot, the sensors detect its presence and guide it to an empty parking spot using LED lights and arrows displayed on an LCD screen. The system then parks the car automatically, using motors and gears to move the car to the designated spot.When the driver returns to retrieve the car, the system uses ultrasonic sensors and LCD screen to guide the driver to the parked car's location. The system then uses the same motors and gears to retrieve the car and move it to the exit, where the driver can take control of the vehicle.The code for the project requires a series of algorithms to detect the car's position, calculate the distance between the car and the sensors, and guide the car to the designated parking spot. The code must be optimized for efficiency and reliability to ensure that the system operates smoothly.

Automatic Car Parking with 7 Segment Display
Charan Sai Ravilla
The system is built to maximize energy efficiency and is very helpful if we want to count the number of cars in the parking lots. This is done by simply incrementing the counter. To accomplish this, the system pairs of ultrasonic sensors, which saves a significant amount of energy. Each pair consists of two sensor pairs that are spaced apart in the opposite direction by a specific amount. The receiver receives the input and feeds it to an 8051 microcontroller. The transmitter is used to send light directly to the receiver. When a car approaches the area where the system is installed, the Ultrasonic sensor module detects it and sends the information to the microcontroller. The microcontroller process this input received. The system is also counting the number of cars that are present at this time and incrementing a counter with each arrival; the count is shown on a 7-segment display. If parking garages are not available, then indicate this on an LED display along with whether or not the vacant space is available. Since the counter should be situated so that only one car can pass at a time, the system also uses Arduino to increase the Bluetooth gate's open position over time.
