Description
The purpose of this project was to design a new railroad crossing for pedestrians and bicyclists in mid-block or urban areas. In order to develop a successful design, the needs of the railroad, the end-users, and the city governments were researched and converted into measurable engineering requirements. For the railroad companies, the most important need was a crossing that presents an effective barrier to users while a train is in the area. For bicyclists and pedestrians (the end-users), the most important need was for the crossing to be both reliable and easily accessible. For the city governments, the most important need was a crossing that is inexpensive yet sturdy. The approach to this project was similar to the approach used in many engineering design processes. First is the Introduction, which provides an overview of the issue and presents the full problem statement. Next is the Research of Prior Art, which details the past solutions to railroad crossings as well as the 3 E's of railroad crossing safety. After this, the customer needs are discussed in the Needs to Requirements section and the process of converting these into measurable engineering requirements is shown. Next, various conceptual design options are shown in the Conceptual Design section and a final conceptual design is chosen based on adherence to the stated requirements. This final conceptual design is then taken into the preliminary design phase and refined until it becomes the final preliminary design. After the Final Preliminary Design Description, the Project Conclusions and Recommendations are presented. Due to time and monetary constraints, this project ends after the preliminary design stage. Despite this, the conclusion of this project is that the final design presented here will be successful if additional resources are obtained to move it forward into the detailed design phase. For now, this project has come to a halt due to UP's reluctance to allow any additional railroad crossings in the Phoenix and Tempe, Arizona areas. It is recommended that city officials and bicyclist/pedestrian action groups continue talks with UP until they agree to allow additional crossings to be built that are geared towards non-motorized users.

My work focuses on the themes of grief, closure, and celebration of life. Life is a catalyst both celebration and grief. Feeling joy when a life is introduced is as common as feeling pain when a life is lost. When I lost my maternal grandmother nearly a year ago, I felt grief accompanied with guilt. I never got a chance to say goodbye since we lived so far apart, her residing in the Philippines and me residing in the United States. In order to get rid of these negative emotions, I sought closure. I attended her funeral, and now I want to celebrate her life through my artwork.
My work comes in two parts: an illustration book titled The Butanding and an illustration exhibition. The book will be published through lulu.com and made available to the public. The exhibition component will be held from March 2nd to March 6th in Gallery 100 as part of my senior exhibition Post Pre-Production with six other colleagues in the School of Art. The illustration book is a narration of a little girl and her growing friendship with a whale shark. The overarching theme of the creative project is closure with the passing away of loved ones.
The Butanding is a narrative illustration book about a young girl befriending the local menace of her village, the whale shark. Similar to my own experience, the main subject—the young girl—of my narrative is shown suffering from grief and guilt over her grandmother’s death. My work illustrates a progression of the young girl’s emotional state as she goes on a journey with the whale shark or locally known in the Philippines as the “butanding”. It provides the scenario of a grieving individual who gets the chance to reconnect with a deceased loved one and rebuild relationships that were lost.

Description
The exhaust system is an integral part of any internal combustion engine. A well- designed exhaust system efficiently removes exhaust gasses expelled from the cylinders. If tuned for performance purposes, the exhaust system can also exhibit scavenging and supercharging characteristics. This project reviews the major components of an exhaust system and discusses the proper design techniques necessary to utilize the performance boosting potential of a tuned exhaust system for a four-stroke engine. These design considerations are then applied to Arizona State University's Formula SAE vehicle by comparing the existing system to a properly tuned system. An inexpensive testing method, developed specifically for this project, is used to test the effectiveness of the current design. The results of the test determined that the current design is ineffective at scavenging neighboring pipes of exhaust gasses and should be redesigned for better performance.

Description
The paper presents a new exhaust header design to replace the current design on Arizona State University's Formula SAE car. Also, the thought process of the design was presented as well as a method of analysis for tuning the exhaust headers. The equation presented was then compared with a computational fluid dynamics model using ANSYS Fluent. It was found that the equation did not match the timing of the CFD model. However, the design does allow for simple changes to be made in order to reduce the length of the exhaust and allow for the correct tuning. Also, the design minimizes interference between the individual headers which is ideal to increase engine performance. The exhaust meets the Formula SAE regulations, and is designed to fit in the new chassis for the FSAE car that ASU will run in 2015. Recommendations were also made to further improve the design and analysis model.

Description
The main objective of this project was to continue research and development of a building integrated solar thermoelectric generator (BISTEG). BISTEG is a promising renewable energy technology that is capable of generating electrical energy from the heat of concentrated sunlight. In order to perform R&D, the performance of different TEG cells and TEG setups were tested and analyzed, proof-of-concepts and prototypes were built. and the performance of the proof-of-concepts and prototypes were tested and analyzed as well. In order to test different TEG cells and TEG setups, a TEG testing apparatus was designed and fabricated. The apparatus is capable of comparing the performance of TEGs with temperature differentials up to 200 degrees C. Along with a TEG testing apparatus, several proof-of-concepts and prototypes were completed. All of these were tested in order to determine the feasibility of the design. All three proof-of-concepts were only capable of producing a voltage output less than 300mV. The prototype, however, was capable of producing a max output voltage of 17 volts. Although the prototype outperformed all of the proof-of-concepts, optimizations to the design can continue to improve the output voltage. In order to do so, stacked TEG tests were performed. After performing the stacked TEG tests, it was determined that the use of stacked TEGs depended on the Fresnel lens chosen. If BISTEG were to use a point focused Fresnel lens, using a stack of TEGs could increase the power density. If BISTEG were to utilize a linear focused Fresnel lens, however, the TEGs should not be stacked. It would be more efficient to lay them out side by side. They can be stacked, however, if the energy density needs to be increased and the costs of the additional TEGs are not an issue.

Description
This thesis examines a variety of techniques implemented in modern senior design classes at Arizona State University with a special focus on the mechanical engineering senior capstone the traditional ABET capstone mechanical engineering capstone course, as well as the InnovationSpace Program. First, an overview regarding the growing profession of engineering and its relation to academic education is examined. Next, program and project overviews of both the capstone senior design course and the InnovationSpace are detailed, followed by a comparison of the two course's curriculum. Finally, key differences are highlighted, and suggestions introduced that might serve to improve both courses in the future. The senior design capstone course was found to lack accountability and diversity leading to a lack of innovative solutions. However, the course simultaneously succeeded in maintaining wellaccepted traditional engineer practices and documentation. The InnovationSpace program on the other hand provides accountability, diversity, and modern approaches to product development.

My creative project involved the creation of a short, abstract animation set to EDM music. It's meant to mimic the graphics displayed in the background of EDM concerts and was inspired by Beeple and the graphics he designed for EDM artist, Zedd. Under the guidance of my director, Meredith Drum, and with help from my second committee member, Muriel Magenta, I was able to use Audacity to edit the music, Autodesk Maya 2016 to model and animate the animation, the HIDA render farm to render the frames using Maya Software and mentalray, Adobe After Effects CC to assemble and edit the animation, and Adobe Media Encoder to export the end product. The final animation included 20,855 individual frames, totaling to 14 minutes and 28 seconds in length. The project takes the viewer through seven worlds to express the idea of feeling isolated in your home, exploring the world, and then returning home with a new perspective. Each world evokes a different emotion through the interaction of its visual and audio design to allow the viewer to experience the intended storyline without explicit characters or plot detail. Due to the importance of maintaining plot flow, I utilized beautiful, yet difficult, design elements including glass textures, ocean shaders, and paint effects to create drastically different world designs specific to each song. These songs were chosen from a variety of EDM artists and edited to flow together seamlessly through each world and evoke a different emotion. Throughout the thesis process, I gained more skills in animation and editing and greatly improved my ability to use each application. While there is plenty of room to grow, I have improved exponentially as an artist from when I began this project to the moment I completed it.

Immersion has become a key buzzword in the theme park industry, with many themed lands and attractions being designed with this objective in mind. This paper defines immersion through the concept of the ironic imagination and examines its role in theme park attractions. A literature review was first conducted to identify general design principles for the creation of immersive theme park attractions. Authentic settings that utilize all of the senses were considered first, along with a system of positive and negative cues for evaluating immersive experiences. The importance of simple and emotional stories was also addressed, before investigating the role that employees and guests play in an immersive attraction. Eight design principles were identified, and using these principles a blue sky design for an immersive theme park attraction was developed. An overview of the attraction is included and accompanied by an analysis of how the design principles were applied.
