Description
In the search for chemical biosensors designed for patient-based physiological applications, non-invasive diagnostic approaches continue to have value. The work described in this thesis builds upon previous breath analysis studies. In particular, it seeks to assess the adsorptive mechanisms active in both acetone and ethanol biosensors designed for breath analysis. The thermoelectric biosensors under investigation were constructed using a thermopile for transduction and four different materials for biorecognition. The analytes, acetone and ethanol, were evaluated under dry-air and humidified-air conditions. The biosensor response to acetone concentration was found to be both repeatable and linear, while the sensor response to ethanol presence was also found to be repeatable. The different biorecognition materials produced discernible thermoelectric responses that were characteristic for each analyte. The sensor output data is presented in this report. Additionally, the results were evaluated against a mathematical model for further analysis. Ultimately, a thermoelectric biosensor based upon adsorption chemistry was developed and characterized. Additional work is needed to characterize the physicochemical action mechanism.

Description
The object of this study was a 26 year old residential Photovoltaic (PV) monocrystalline silicon (c-Si) power plant, called Solar One, built by developer John F. Long in Phoenix, Arizona (a hot-dry field condition). The task for Arizona State University Photovoltaic Reliability Laboratory (ASU-PRL) graduate students was to evaluate the power plant through visual inspection, electrical performance, and infrared thermography. The purpose of this evaluation was to measure and understand the extent of degradation to the system along with the identification of the failure modes in this hot-dry climatic condition. This 4000 module bipolar system was originally installed with a 200 kW DC output of PV array (17 degree fixed tilt) and an AC output of 175 kVA. The system was shown to degrade approximately at a rate of 2.3% per year with no apparent potential induced degradation (PID) effect. The power plant is made of two arrays, the north array and the south array. Due to a limited time frame to execute this large project, this work was performed by two masters students (Jonathan Belmont and Kolapo Olakonu) and the test results are presented in two masters theses. This thesis presents the results obtained on the north array and the other thesis presents the results obtained on the south array. The resulting study showed that PV module design, array configuration, vandalism, installation methods and Arizona environmental conditions have had an effect on this system's longevity and reliability. Ultimately, encapsulation browning, higher series resistance (potentially due to solder bond fatigue) and non-cell interconnect ribbon breakages outside the modules were determined to be the primary causes for the power loss.

Description
While the piezoelectric effect has been around for some time, it has only recently caught interest as a potential sustainable energy harvesting device. Piezoelectric energy harvesting has been developed for shoes and panels, but has yet to be integrated into a marketable bicycle tire. For this thesis, the development and feasibility of a piezoelectric tire was done. This includes the development of a circuit that incorporates piezoceramic elements, energy harvesting circuitry, and an energy storage device. A single phase circuit was designed using an ac-dc diode rectifier. An electrolytic capacitor was used as the energy storage device. A financial feasibility was also done to determine targets for manufacturing cost and sales price. These models take into account market trends for high performance tires, economies of scale, and the possibility of government subsidies. This research will help understand the potential for the marketability of a piezoelectric energy harvesting tire that can create electricity for remote use. This study found that there are many obstacles that must be addressed before a piezoelectric tire can be marketed to the general public. The power output of this device is miniscule compared to an alkaline battery. In order for this device to approach the power output of an alkaline battery the weight of the device would also become an issue. Additionally this device is very costly compared to the average bicycle tire. Lastly, this device is extreme fragile and easily broken. In order for this device to become marketable the issues of power output, cost, weight, and durability must all be successfully overcome.

Description
Potential induced degradation (PID) due to high system voltages is one of the major degradation mechanisms in photovoltaic (PV) modules, adversely affecting their performance due to the combined effects of the following factors: system voltage, superstrate/glass surface conductivity, encapsulant conductivity, silicon nitride anti-reflection coating property and interface property (glass/encapsulant; encapsulant/cell; encapsulant/backsheet). Previous studies carried out at ASU's Photovoltaic Reliability Laboratory (ASU-PRL) showed that only negative voltage bias (positive grounded systems) adversely affects the performance of commonly available crystalline silicon modules. In previous studies, the surface conductivity of the glass surface was obtained using either conductive carbon layer extending from the glass surface to the frame or humidity inside an environmental chamber. This thesis investigates the influence of glass surface conductivity disruption on PV modules. In this study, conductive carbon was applied only on the module's glass surface without extending to the frame and the surface conductivity was disrupted (no carbon layer) at 2cm distance from the periphery of frame inner edges. This study was carried out under dry heat at two different temperatures (60 °C and 85 °C) and three different negative bias voltages (-300V, -400V, and -600V). To replicate closeness to the field conditions, half of the selected modules were pre-stressed under damp heat for 1000 hours (DH 1000) and the remaining half under 200 hours of thermal cycling (TC 200). When the surface continuity was disrupted by maintaining a 2 cm gap from the frame to the edge of the conductive layer, as demonstrated in this study, the degradation was found to be absent or negligibly small even after 35 hours of negative bias at elevated temperatures. This preliminary study appears to indicate that the modules could become immune to PID losses if the continuity of the glass surface conductivity is disrupted at the inside boundary of the frame. The surface conductivity of the glass, due to water layer formation in a humid condition, close to the frame could be disrupted just by applying a water repelling (hydrophobic) but high transmittance surface coating (such as Teflon) or modifying the frame/glass edges with water repellent properties.

Description
This report presents the effects and analysis of the effects of Pulsed-Gas Metal Arc Welding's (P-GMAW) on Lean Duplex stainless steel. Although the welding of Duplex and Super Duplex Stainless steels have been well documented in both the laboratory and construction industry, the use of Lean Duplex has not. The purpose for conducting this research is to ensure that the correct Ferrite-Austenite phase balance along with the correct welding procedures are used in the creation of reactor cores for new construction nuclear power generation stations. In this project the effects of Lincoln Electrics ER-2209 GMAW wire are studied. Suggestions and improvements to the welding process are then proposed in order to increase the weldability, strength, gas selection, and ferrite count. The weldability will be measured using X-Ray photography in order to determine if any inclusions, lack of fusion, or voids are found post welding, along with welder feedback. The ferritic point count method in accordance with ASTM A562-08, is employed so that the amount of ferrite and austenite can be calculated in the same manor that is currently being used in industry. These will then be correlated to the tensile strength and impact toughness in the heat-affected zone (HAZ) of the weld based on the ASTM A923 testing method.

Description
Uniforms and logos are an essential part of sports teams and are created with the intention of representing the city and state of their respective teams. More than a uniform: How culture influences the creation of Arizona sports logos and jerseys presents a look at the conversations and processes undergone before teams are able to unveil their new threads. Four local professional teams are involved with this project: Phoenix Suns, Arizona Diamondbacks, Arizona Coyotes and Arizona Cardinals. Members from each of the organizations were interviewed, in addition to Greg Fisher of Fisher Design. Information was gathered from each of those interviews in addition to research done on the history of each of the team’s uniforms. The information was then created into a documentary that consists of visual and verbal components. The film highlights how each team attempts to represent Arizona and its culture when it comes to what they are wearing on the field, court or ice. The interviews capture the mindset of creative teams as they explore growing new ideas and looks, in addition to a historical delve into two of the team’s debuts in the 1990s. Many of Arizona’s sports teams have much more behind their logos and jerseys than meets the eye. The project taught me how adapt broadcast skills into documentary style storytelling and how important visuals are for longer features. The interviews showed that so many things are taken into consideration when designing a sports logo or uniform and the process can take either months or years to finally reach fruition.

Description
The purpose of this thesis is to analyze how colleges and universities throughout the United States market its study abroad programs to students. The author reflects not only on this central question but also explores the evolving digital age in which we are consumed and how it has changed the marketing environment entirely.
The following research questions spurred the curiosity for this knowledge. These questions are:
1. How does Arizona State University market its study abroad programs?
a) How does ASU most effectively market its study abroad programs to students—what marketing tools are needed and used?
2. How do other college and universities throughout the United States market its study abroad programs?
b) How do they best market its study abroad programs to students—what marketing tools are needed and used?
3. How has this new digital age shaped the marketing environment today?
4. How do you develop relevant marketing strategies for a specific study abroad program in order to increase participation?
Before answering the preceding questions, this thesis first examines the origin of international education and its history.
Additionally, the author of this thesis created a series of questions that was sent via SurveyMonkey.com to various college and university study abroad offices, directors, advisors and marketing specialists throughout the U.S (a total of 18 schools from various parts of the region responded to the 37 question survey). This in turn allowed the author to answer a large portion of the above research questions. See attached documents (Appendix A) for a list of all the questions asked via survey, as well as each school’s response.
After a thorough analysis of the above research questions, the author focuses on the development of marketing strategies to help promote a specific faculty-led study abroad program at Arizona State University’s Walter Cronkite School of Journalism and Mass Communication (the official name for that program: “Cronkite Euro: Social Media Across Cultures: The European Perspective”). It is the analysis of the above research questions that in turn helped the author create marketing strategies that were tailored to this specific faculty-led study abroad program.
These marketing activities included the expansion of Cronkite Euro’s social media presence, specifically by creating an Instagram account for the study abroad program (@asucronkiteuro). Another major marketing activity included the expansion of Cronkite Euro’s online presence. The author of this essay completely revamped the study abroad program’s website so as to adequately keep up with the tech-savvy, digital natives of today (www.asucronkiteuro.com). The importance of implementing these specific marketing strategies will be later discussed in part IV of the thesis.

This full-length, two-act play explores the way loss brings together and tears apart two families in the United States, a lower-middle class Mexican family and a relatively wealthy white family. Throughout the play we explore family dynamics, culture, and how we all ultimately cope with navigating a complex and often devastating world. While this thesis project has completed the honors requirements, the play itself is still under construction. The version you see here is a final thesis project, but not a final product.

Woman with Wanderlust is a travel blog made to break down the stereotypes of female travelers as they are portrayed in mass media. The idea came to me when I was preparing to study abroad in Morocco and every person I talked to felt the need to remind me how dangerous the world was for a woman on her own. There were many references to the popular movie ‘Taken’ starring Liam Neeson. When I decided I wanted to continue the blog on my backpacking trip through Europe, once again ‘Taken’ was referenced but people also insisted I was going to fall in love with an Italian man and never come home. It felt, to me, that the world saw the female traveler as naive and weak or in need of a man in her life. In contrast men are often encouraged to take years off to travel, to seek adventure or find themselves.
I decided I could use my education from the Cronkite School in writing, photography and social media to produce a resource for women looking to travel abroad. I could tell stories of my personal experiences that could both inspire and prove that a solo trip can be done. I also wanted to touch on topics that are not generally covered by popular travel blogs since they are specific to women. Topics like how to dress, making sure you travel during the day if you’re traveling alone and finding birth control or feminine hygiene products when you are traveling.
I funded the trip myself and currently the blog is designed, written and photographed entirely by me. Moving forward I would like to feature other women on my blog, especially those who have made travel a priority or a career. I plan on continuing to build the blog, hopefully gaining sponsors and becoming a more well known resources, and helping change the landscape of travel and travel blogging to become more female friendly.
