Description
The goal of this project was to explore biomimetics by creating a jellyfish flying device that uses propulsion of air to levitate while utilizing electromyography signals and infrared signals as mechanisms to control the device. Completing this project would require knowledge of biological signals, electrical circuits, computer programming, and physics to accomplish. An EMG sensor was used to obtain processed electrical signals produced from the muscles in the forearm and was then utilized to control the actuation speed of the tentacles. An Arduino microprocessor was used to translate the EMG signals to infrared blinking sequences which would propagate commands through a constructed circuit shield to the infrared receiver on jellyfish. The receiver will then translate the received IR sequence into actions. Then the flying device must produce enough thrust to propel the body upwards. The application of biomimetics would best test my skills as an engineer as well as provide a method of applying what I have learned over the duration of my undergraduate career.

Description
Engineering is a heavily male-dominated field and females are significantly less likely to choose an engineering-related major or career path. At the age of six years old, females start believing that their male peers are smarter than them, leading them to pursue less ambitious careers. The children's book Lyla B. An Engineering Legacy was created to encourage more young girls to discover their own potential and pursue engineering as a career. To explore the efficacy of the book on its target consumers, a pilot study was performed with first and second grade children. The participants' engineering knowledge; fixed and failure mindset beliefs; STEM (Science, Technology, Engineering, and Math) interest, competency, and career aspirations; and stereotype beliefs were evaluated before and after being read the book to determine if the story has a positive impact on children. Additionally, the satisfaction of the participants towards both the book and main character were analyzed quantitatively and qualitatively. Overall, the results of the study suggest that the book has a positive impact on the interest and competency of STEM fields and the stereotype beliefs that the children had towards engineers. The study also suggests that the book decreases fixed and failure mindsets and that the participants were satisfied with the overall concept of the book and main character, Lyla.

Description
In this creative project, our goal was to establish a student lead service organization dedicated to raising money and awareness for a selected medical issue through an interactive carnival event. In doing so, we were able to identify the potential obstacles and pathways that are required for service organizations within Arizona State University. Our experience provides a guideline for future students looking to organize charitable events on campus. This paper discusses several essential skills for running a charitable student organization, including establishing a brand, managing finances, cultivating business relationships, and marketing the cause. It is our hope that future students can learn from our experience and find success in similar endeavors.

Description
Diabetes mellitus is a disease characterized by many chronic and acute conditions. With the prevalence and cost quickly increasing, we seek to improve on the current standard of care and create a rapid, label free sensor for glycated albumin (GA) index using electrochemical impedance spectroscopy (EIS). The antibody, anti-HA, was fixed to gold electrodes and a sine wave of sweeping frequencies was induced with a range of HA, GA, and GA with HA concentrations. Each frequency in the impedance sweep was analyzed for highest response and R-squared value. The frequency with both factors optimized is specific for both the antibody-antigen binding interactions with HA and GA and was determined to be 1476 Hz and 1.18 Hz respectively in purified solutions. The correlation slope between the impedance response and concentration for albumin (0 \u2014 5400 mg/dL of albumin) was determined to be 72.28 ohm/ln(mg/dL) with an R-square value of 0.89 with a 2.27 lower limit of detection. The correlation slope between the impedance response and concentration for glycated albumin (0 \u2014 108 mg/dL) was determined to be -876.96 ohm/ln(mg/dL) with an R-squared value of 0.70 with a 0.92 mg/dL lower limit of detection (LLD). The above data confirms that EIS offers a new method of GA detection by providing unique correlation with albumin as well as glycated albumin. The unique frequency response of GA and HA allows for modulation of alternating current signals so that several other markers important in the management of diabetes could be measured with a single sensor. Future work will be necessary to establish multimarker sensing on one electrode.

Description
Growing concern over health risks associated with environmental contaminants has prompted an increase in the search for effective detection methods. The available options provide acceptable sensitivity and specificity, but with high purchase and maintenance costs. Herein, a low-cost, portable environmental contaminant sensor was developed using electrochemical techniques and an efficient hydrogel capture mechanism. The sensor operates with high sensitivity and maintains specificity without the added requirement of extensive electrode modification. Rather, specificity is obtained by choosing specific potential regions in which individual contaminants show reduction or oxidation activity. A calibration curve was generated showing the utility of the sensor in detecting gas compounds reliably in reference to a current state of the art sensor. Reusability of the sensor was also demonstrated with a cyclic exposure test in which response reversibility was observed. As such, the investigated sensor shows great promise as a replacement technology in the current environmental contaminant detector industry.

Description
Spending time outdoors can have a positive impact on the physical and mental health of individuals. These physiological and psychological benefits were comprehensively reviewed, accompanied by a brief history of these views in American society and how modern programs are promoting outdoor activity. Some of the populations targeted in this research include children, veterans, the elderly, and the clinically ill. A guidebook for Arizona outdoor adventures \u2014 containing original landscape photography \u2014 was created to encourage ASU students to explore local hikes, campsites, and other outdoor opportunities near the city of Phoenix. Each entry contained a brief description of the area or trail, along with the distance from the ASU Tempe campus and information on the length and difficulty of the hike, if applicable. A section at the end of the book was aimed at education readers on basic outdoor survival protocol, as many people venture into the wild with very little understanding of the dangers associated with their activities. A website was made that mirrors the guidebook, but was intended to be a more accessible method of sharing our information. The final component of the project involved maintaining a social media account over the course of the year, allowing us to expand our reach to people beyond ASU and this community. Over the course of the project, the account gained a large following, and several posted photos went on to be featured on prominent regional accounts. By combining the four components described previously, several resources were created for people, particularly students attending ASU, to gain a better understanding of the outdoor adventures available to them, and the benefits that spending time surrounded by nature can have.

Description
The goal of this creative project is to document my grandmother’s traditional Gujarati recipes with the hopes of preserving her life and passion for cooking. This process included library research to investigate the history of Indian and Gujarati cuisine, spending time in the kitchen documenting the recipes in their entirety, practicing them on my own, writing the cookbook and including passages that weave in the history, my grandmother’s stories, and techniques and tools. After completing this process, the significant findings related to my grandmother’s life and her journey from birth to now. Her marriage to my grandfather at a young age, her journey and those who influenced her ability to cook, and her impact on my family were all effects that I had understood and known during my experiences with my grandmother. In this journey, I learned more about her thoughts and experiences that I never knew before. Our relationship has deepened ten-fold and while she may not be with me forever, I now have a tangible part of her that I can keep with me for the rest of my life.

Description
The novella Flicker by Rachel Ponstein is a climate fiction story. It draws influence from the post-apocalyptic and dystopian genres as well as classic gothic literature. The story utilizes elements of gothic literature including Freud's Uncanny, uneven framing, and bildungsroman. It also utilizes subhuman species to incite conversation about the importance of perspective and the use of an alternative lens on the post-Reckoning world. The disaster story is ambiguous to focus the reader on the importance of the characters and their progress throughout the journey rather than the overall plotline. The analysis below serves as an explanation for the intentional decisions made to fit a sub-genre and engage the reader in an intellectual conversation about the issues broached.

Description
The goal of this project was to create a card game that would quickly and easily allow medical professionals to learn important information. This project seeks to advance ways in which medical staff gain information about disease outbreaks through the creation of a card game which teaches players the proper steps and procedure to triage and treat patients who are suspected to have Ebola Hemorrhagic Fever, which was not done properly during the recent outbreak. To create this game, research was conducted on the information given by the Center for Disease Control and Prevention (CDC) on the various steps to triaging those who were suspected of having Ebola. Various prototypes of the game were made and tested to optimize the win-lose ratio while still being an enjoyable game to play. This card game is fast-paced, small, and can be played either individually or with more than one person. It is loosely based off of Solitaire. This game has gone through three prototypes of the cards as well as a few brief testing periods. Through the methods and procedure used in this game's creation, it has been concluded that this method is a great way to easily teach players a proper procedure, and that this method of game can be applied to other disease breakouts and even to other fields where information must be learned quickly. Future steps for this game include improving the graphic art used in the cards, and continuing on to create a smartphone application.
