The team has designed and built a golf swing analyzer that informs the user of his mistakes while putting with a golf club. The team also interfaced a Linux program with the analyzer that allows the user to review the flaws in his golf swing. In addition, the application is more personalized than existing devices and tailored to the individual based on his level of experience. The analyzer consists of an accelerometer, gyroscope, magnetometer, vibration motor, and microcontroller that are connected on a board that attaches to the top of the shaft of a golf club, fitting inside a 3D printed case. The team has assembled all of the necessary hardware, and is able to successfully display critical parameters of a golf putt, as well as send instant feedback to the user. The final budget for this project was $378.24

Description
The purpose of the solar powered quadcopter is to join together the growing technologies of photovoltaics and quadcopters, creating a single unified device where the technologies harmonize to produce a new product with abilities beyond those of a traditional battery powered drone. Specifically, the goal is to take the battery-only flight time of a quadcopter loaded with a solar array and increase that flight time by 33% with additional power provided by solar cells. The major concepts explored throughout this project are quadcopter functionality and capability and solar cell power production. In order to combine these technologies, the solar power and quadcopter components were developed and analyzed individually before connecting the solar array to the quadcopter circuit and testing the design as a whole. Several solar copter models were initially developed, resulting in multiple unique quadcopter and solar cell array designs which underwent preliminary testing before settling on a finalized design which proved to be the most effective and underwent final timed flight tests. Results of these tests are showing that the technologies complement each other as anticipated and highlight promising results for future development in this area, in particular the development of a drone running on solar power alone. Applications for a product such as this are very promising in many fields, including the industries of power, defense, consumer goods and services, entertainment, marketing, and medical. Also, becoming a more popular device for UAV hobbyists, such developments would be very appealing for leisure flying and personal photography purposes as well.

Description
Every engineer is responsible for completing a capstone project as a culmination of accredited university learning to demonstrate technical knowledge and enhance interpersonal skills, like teamwork, communication, time management, and problem solving. This project, with three or four engineers working together in a group, emphasizes not only the importance of technical skills acquired through laboratory procedures and coursework, but the significance of soft skills as one transitions from a university to a professional workplace; it also enhances the understanding of an engineer's obligation to ethically improve society by harnessing technical knowledge to bring about change. The CC2541 Smart SensorTag is a device manufactured by Texas Instruments that focuses on the use of wireless sensors to create low energy applications, or apps; it is equipped with Bluetooth Smart, which enables it to communicate wirelessly with similar devices like smart phones and computers, assisting greatly in app development. The device contains six built-in sensors, which can be utilized to track and log personal data in real-time; these sensors include a gyroscope, accelerometer, humidifier, thermometer, barometer, and magnetometer. By combining the data obtained through the sensors with the ability to communicate wirelessly, the SensorTag can be used to develop apps in multiple fields, including fitness, recreation, health, safety, and more. Team SensorTag chose to focus on health and safety issues to complete its capstone project, creating applications intended for use by senior citizens who live alone or in assisted care homes. Using the SensorTag's ability to track multiple local variables, the team worked to collect data that verified the accuracy and quality of the sensors through repeated experimental trials. Once the sensors were tested, the team developed applications accessible via smart phones or computers to trigger an alarm and send an alert via vibration, e-mail, or Tweet if the SensorTag detects a fall. The fall detection service utilizes the accelerometer and gyroscope sensors with the hope that such a system will prevent severe injuries among the elderly, allow them to function more independently, and improve their quality of life, which is the obligation of engineers to better through their work.

Description
This paper analyzes existing literature regarding how excessive aggravating stimuli in a hospital environment can reduce the quality and quantity of sleep. The sick and injured are most sensitive to aggravating stimuli and the most vulnerable to poor sleep conditions. For individuals with anxiety, stress, hypersensitivity, or conditions such as Autism Spectrum Disorder (ASD), as additional stress during rest periods could seriously harm development and overall well-being. While solutions have been proposed and tested, there is no one solution to the problem. One possible solution is to design a device that monitors a patient's room and alerts a nurse or parent of aggravating stimuli so that it can be removed.

Description
The Built-In Self-Test for Simultaneous Transmit and Receive (BIST for STAR) will be able to solve the challenges of transmitting and receiving at the same time at the same frequency. One of the major components is the STAR antenna which transmits and receives along the same pathway. The main problem with doing both on the same path is that the transmit signal is usually much stronger in power compared to the received signal. The transmit signal has echoes and leakages that cause self-interference, preventing the received signal from being properly obtained. The solution developed in this project is the BIST component, which will help calculate the functional gain and phase offset of the interference signal and subtract it from the pathway so that the received signal remains. The functions of the proposed circuit board can be modeled in Matlab, where an emulation code generates a random, realistic functional gain and delay for the interference. From the generated values, the BIST for STAR was simulated to output what the measurements would be given the strength of the input signal and a controlled delay. The original Matlab code models an ideal environment directly recalculating the functional gain and phase from the given measurements in a second Matlab script. The actual product will not be ideal; a possible source of error to be considered is the effect of thermal noise. To observe the effect of noise on the BIST for STAR's performance, the Matlab code was expanded upon to include a component for thermal noise, and a method of analyzing the results of the board.

Description
Dysmorphia is a series of large-scale paintings that address the relationship between a body image disorder called Body Dysmorphia (BDD) and plastic surgery. The audience sees women of all colors, shapes and sizes in their most vulnerable state. However, the shapes of their bodies and the abnormal background are not what we are used to seeing. Presented in the IAP Studios, Dysmorphia aims to start a conversation around the rising global occurrences of cosmetic procedures, the patients who suffer from Body Dysmorphia, and how the two subjects relate. Plastic surgery is a highly controversial conversation that the world is currently having. However, BDD is not a common topic that comes up within those discussions. Many surgeons may not realize or choose to ignore the fact that a vast majority of their patients have a body image disorder. Sometimes the patients themselves may not even realize it. Whether we believe plastic surgery is a positive life-changing choice or that it takes advantage of those who have disorders such as BDD, the end result will be up to the audience to determine. By establishing a connection between the two contrasting ideals, society can then begin to identify where they might fit in the conversation. Dysmorphia aims to spark informative discussions about these kinds of social issues by exploring the female body and bringing to light plastic surgery's attempt to alter it.

Description
Abstract Retrograde presents questions about the creation and value of art through a graphic novel. Materials used to create the work were illustration paper, ink, brushes, and printed screen tones. The piece was created in four stages: first, each panel was sketched into the first draft; second, the sketch was researched and fully developed into a complete drawing; third, the sketch was completely traced with ink and texture was added; finally, the drawing tones were added with ink and screen tones. The plot of Retrograde revolves around the protagonist, Vera, as she attempts to find a place for her art in an artistic community that rejects her for her lack of commercial success and for the advantages she got through connections. When Vera appears to have succeeded, a sudden plot twist reveals a conspiracy which undermines her success. By following Vera, the novel illustrates a corrupt artistic society in which the value of art is established by a small amount of artistic elites. The written portion of the project expounds on the various ideas that drove the novel, including how art forms like graphic novels come to be situated low in artistic hierarchies and how interpretations can be negatively guided by already established institutions. Among some of the theorists referenced within the paper are Walter Benjamin, Clement Greenberg, and Susan Sontag. In conclusion, the project illustrates an inclination to judge art by potential commercial value and by already established hierarchies, limiting the possibilities of new interpretations and shifts in those same hierarchies. Keywords: art, art theory, graphic novels

Delusions of Grandeur: A Collection of Emotionally Revealing and Probably Not Funny Comedy Vignettes
Description
This creative project, titled What Did You Expect?, is five comedy plays all written and edited by me (with the help of my director Jason Scott), to ideally be performed all in a single night of entertainment. All five plays are united with an overarching theme, which sits somewhere on the borders of subverting expectations and the fortitude of human emotion. I have a long history writing sketch comedy (for a college student), but each of these plays were all written with the specific intention to divert from the style of short-form comedy to longer stories with dynamic characters and plot movement, rather than circling around one singular joke. Each play tells a story placed in a setting with specific expectations, then follows an absurd character as she or he subverts each and every one of those expectations. There are five plays. The first and fifth play comprise the two parts of the story of Leonardo Da Vinci and Mona Lisa, their secret love affair, and it discusses, through a series of misunderstandings and insults, broad realizations about love and art. The second is the story of a therapy session between a seasoned professional and a nightmare patient, and it follows the therapist's absurd descent into (brief) madness, as well as the patient's ascent into (brief) catharsis. The third play serves as a transition; a short monologue by a 13-year old boy delivering a science fair presentation about a hermit crab \u2014 only to realize that he and the crab have more in common than he would like to think. Finally, the fourth play is called Space Cowboy, and to discuss it any further would take all the fun out of reading it. Overall, the project was about self-discovery through a new form of comedy writing, and hopefully it's funny enough for someone to read. Hell, I'd even take a skim. If someone skimmed the plays, I'd consider this creative project a success. You've already read the abstract though, so we're off to a good start! If it's not up to your standards, all I have to say is...what did you expect?

Description
The apparent phenomenon of the human eye retaining images for fractions of a second after the light source has gone is known as Persistence of Vision. While its causes are not fully understood, it can be taken advantage of in order to create illusions which trick the mind into perceiving something which, in actuality, is very different from what the mind portrays. It has motivated many creative engineering technologies in the past and is the core for how we perceive motion in movies and animations. This project applies the persistence of vision concept to a lesser explored medium; the wheel of a moving bicycle. The motion of the wheel, along with intelligent control of discrete LEDs, create vibrant illusions of solid lines and shapes. These shapes make up the image to be displayed on the bike wheel. The rotation of the bike wheel can be compensated for in order to produce a standing image (or images) of the user's choosing. This thesis details how the mechanism for conducting the individual LEDs was created in order to produce a device which is capable of delivering colorful, standing images of the user's choosing.

Description
RRAM is an emerging technology that looks to replace FLASH NOR and possibly NAND memory. It is attractive because it uses an adjustable resistance and does not rely on charge; in the sub-10nm feature size circuitry this is critical. However, RRAM cross-point arrays suffer tremendously from leakage currents that prevent proper readings in larger array sizes. In this research an exponential IV selector was added to each cell to minimize this current. Using this technique the largest array-size supportable was determined to be 512x512 cells using the conventional voltage sense amplifier by HSPICE simulations. However, with the increase in array size, the sensing latency also remarkably increases due to more sneak path currents, approaching 873 ns for the 512x512 array.
