Description
A bicycle tour is an unusual thing, one that often defies the expectations of the first-time touring cyclist. In this report, the experience of touring cycling is examined in two parts: a narrative documenting the author's tour down the Pacific Coast, and a reflective work that examines the journey and the major themes which persist throughout. In examining the trip, two major dichotomies arose as themes. The first major dichotomy is found in the expectation of a solitary experience for one who is touring solo. In reality, tours are often built on the goodwill of others in the cycling community. On this particular tour, a website called Warmshowers was central to this point. By offering lodging to tired touring cyclists who would otherwise camp alone, this website serves to bring the cycling community together, and allows for connections that would otherwise never exist to be formed. However, it is true that much of a solo tour is, in fact, spent in solitude. This allows a cyclist long periods for self-reflection and meditation, an opportunity to strengthen one's connection with oneself and the natural world around them. The second is a contrast between the planning that goes into embarking on a long trip and the entropy and randomness that inevitably causes the experience to wildly differ from said plan. When the unexpected occurs, there are two options: to reject the unknown and cling to the framework one sets out for themselves, or to embrace the unexpected and see where it takes you. Often, diverting from the plan can allow for new and exciting experiences. However, there is also value to the framework and stability afforded by adhering to a plan. Through these experiences and more, a bicycle tour changes the way one looks at the world.

The Lightning Audio capstone group, consisting of Brian Boerhinger, Rahul Nandan, Jaime Ramirez, and Niccolo Magnotto (myself), united in the effort to prove the feasibility of a consumer grade plasma arc speaker. This was achieved in group's prototype design, which demonstrates the potential for a refined product in its conventional interfacing, casing, size, safety, and aesthetics. If the potential for an excellent ionization-based loudspeaker product were realized, it would be highly profitable in its reasonable cost of production, novelty, and place in a large and fitting market.

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 honors thesis presented in this document describes an extension to an electrical engineering capstone project whose scope is to develop the receiver electronics for an RF interrogator. The RF interrogator functions by detecting the change in resonant frequency of (i.e, frequency of maximum backscatter from) a target resulting from an environmental input. The general idea of this honors project was to design three frequency selective surfaces that would act as surrogate backscattering or reflecting targets that each contains a distinct frequency response. Using 3-D electromagnetic simulation software, three surrogate targets exhibiting bandpass frequency responses at distinct frequencies were designed and presented in this thesis.

This honors thesis explores the potential use of LoRa technology for detecting moisture in a diaper. Tests of both onboard and external humidity sensors coupled with LoRa transmission are incredibly promising. The potential scale of the final device also shows much promise, measuring smaller than a U.S. dime. However, the estimated cost for producing these proof-of-concept units in bulk is $19.41 per unit. While this is believed to be a pessimistic estimate of the price, the cost of production remains too high regardless for large-scale implementation. The thesis concludes by emphasizing the need for further research and development to optimize the design and reduce the cost of production. Despite the limitations imposed by price, the idea of using LoRa in detecting moisture in a diaper remains intriguing and promising, however, RFID technology has many advantages, such as size, cost, and passive power features.

The Mary-El tarot deck is famous in the tarot community for its intense spiritual power and esoteric imagery. By analyzing its major arcana and investigating the symbology featured therein, for purposes of making the deck accessible to others, I discover a rich world of flowing energies and underlying transcendence. I've used writing to document my journey and discoveries of the internal self. I present these writings as my thesis, and I demonstrate my understanding of the cards through tarot readings.

In the world we live in today, nothing is impossible. Due to the advancements of technology, humans around the globe are able to hold computers that fit within the size of their pocket. These computers can do marvelous things, however run off batteries. These batteries need to be charged and up until a little while ago there was only one option available: wired chargers; however, because of the advancement of technology society has created a way to transfer power via magnetic fields. Now this concept has been around for a long time since the days of Nikola Tesla but just recently society has been able to apply his discoveries to charging these computers in our pockets. Unfortunately, the current models of these chargers come with a drawback as they are less efficient than wired chargers. However, this is the question our group has set out to answer. Is there any way possible to improve the efficiency of these wireless chargers so they are equal or even more efficient than wired chargers. This paper explores how to improve the efficiency in wireless chargers. Through research, simulations and testing the group has discovered areas that efficiency can be improved as well as makes recommendations to change the current wireless chargers on the market today. This paper also explores future applications of wireless chargers that can not only make life much easier but could also save lives in some cases. These applications can have many effects on hospitality, the medical field, as well as the supply chain and logistics of America.

The Founders Lab Thesis tasked each team with taking an idea and trying to form a business out of it. In the process, the thesis director would be there to guide each team and provide expertise where needed. The venture that was assigned originally to our team was a posture correcting device, however after numerous attempts to correspond reliably with the developers of this technology, it was decided that the team should move on to a new idea. Therefore, our team took on a venture named Altion Security: an initiative with the main goal being the safekeeping of customers interests. The product that we were tasked with is a bike alarm that simply rings out when it detects someone tampering with it. This product is a solution to the problem of bike thefts. 2 million bikes are stolen each year in North America, which translates roughly to a theft every 30 seconds (Project 529).
There are quite a few readily available products that one can buy if one looks past some of their flaws. A lot of these alarms either require a user to carry an extra communication device, or they are too big or expensive. The proposed solution merges all desirable features of a bike alarm into one module. In light of this, surveys were conducted to ascertain what these qualities would need to be. The top considerations for purchasing this alarm were how costly it would be, the false detection rate, and also the battery life. Additionally, the features that were most requested was the inclusion of a GPS and a camera. In order to incorporate these features, a three year plan was formulated which would culminate into a bike network in which each bike could communicate with other bikes. This would allow for an IOT network to be established, thus far exceeding expectations. The price point for this alarm is USD $10.00-15.00 and can come in a variety of colors. Additionally, this concept can be applied to many different scenarios, from protecting boats/jet skis and other aquatic vehicles, to houses as well. Furthermore, one could miniaturize this technology to be used in jewelry or accessories.

Description
The ability of magnetic resonance imaging (MRI) to image any part of the human body without the effects of harmful radiation such as in CAT and PET scans established MRI as a clinical mainstay for a variety of different ailments and maladies. Short wavelengths accompany the high frequencies present in high-field MRI, and are on the same scale as the human body at a static magnetic field strength of 3 T (128 MHz). As a result of these shorter wavelengths, standing wave effects are produced in the MR bore where the patient is located. These standing waves generate bright and dark spots in the resulting MR image, which correspond to irregular regions of high and low clarity. Coil loading is also an inevitable byproduct of subject positioning inside the bore, which decreases the signal that the region of interest (ROI) receives for the same input power. Several remedies have been proposed in the literature to remedy the standing wave effect, including the placement of high permittivity dielectric pads (HPDPs) near the ROI. Despite the success of HPDPs at smoothing out image brightness, these pads are traditionally bulky and take up a large spatial volume inside the already small MR bore. In recent years, artificial periodic structures known as metamaterials have been designed to exhibit specific electromagnetic effects when placed inside the bore. Although typically thinner than HPDPs, many metamaterials in the literature are rigid and cannot conform to the shape of the patient, and some are still too bulky for practical use in clinical settings. The well-known antenna engineering concept of fractalization, or the introduction of self-similar patterns, may be introduced to the metamaterial to display a specific resonance curve as well as increase the metamaterial’s intrinsic capacitance. Proposed in this paper is a flexible fractal-inspired metamaterial for application in 3 T MR head imaging. To demonstrate the advantages of this flexibility, two different metamaterial configurations are compared to determine which produces a higher localized signal-to-noise ratio (SNR) and average signal measured in the image: in the first configuration, the metamaterial is kept rigid underneath a human head phantom to represent metamaterials in the literature (single-sided placement); and in the second, the metamaterial is wrapped around the phantom to utilize its flexibility (double-sided placement). The double-sided metamaterial setup was found to produce an increase in normalized SNR of over 5% increase in five of six chosen ROIs when compared to no metamaterial use and showed a 10.14% increase in the total average signal compared to the single-sided configuration.
