Description
This study is a qualitative analysis that makes use of Rick Williams’ Personal Impact Assessment (PIA) to gauge the feelings, narratives, and intuitions that people receive when they view photographs of criminal defendants being made to do a “perp walk.” Participants gave their impressions, which were then categorized and analyzed, along with other statements that they made during an interview outside of the PIA. This study attempted to understand better the received messages of the common media practice of spreading images of perp walks.

Description
The ASU Compact X-ray Free Electron Laser (CXFEL) is a first of its kind instrument that will illuminate the processes of life and allow scientists to create more effective treatments for disease. The dimensions of the linear accelerator (LINAC) cavities must remain stable during operation, for a change in the geometry alters the standing wave microwave energy resonance within the cavities and leads to reflected rather than coupled and useful microwave energy to electric field coupling. This disturbs the electron bunch acceleration dynamics critical to the ultimate generation of x-ray pulses. Cooling water must be supplied to the electron generating RF-GUN, and linear accelerator (LINAC) structures at unique flowrate and temperature setpoints that are specific to the operating mode of the CXFEL. Design specifications for the water supply to the RF-GUN and three LINACs and were made for the nominal operating mode, which adds a 3 kW heat load to the water. To maintain steady cavity dimensions, water must be supplied to each device under test at 30.0 ºC ± 0.06 ºC. The flowrate of water must be 3.5 GPM to the RF-GUN and 2.5 GPM to each of the three LINACs with ± 0.01 GPM flowrate resolution. The primary function of the Dedicated-Precision Thermal Trim Unit (D-PTTU) is to control the flowrate and temperature of water supply to each device under test. A simplified model of the system was developed to select valves that would meet our design specifications for flowrate and temperature control. After using this model for valve selection, a detailed system model was created to simulate relevant coupled-domain physics of the integrated system. The detailed system model was used to determine the critical sensitivities of the system and will be used to optimize the performance of the system in the future. Before the detailed system model can be verified and tuned with experiments, the sensors were calibrated in an ice-bath to ensure the sensors measure accurate and precise values. During initial testing, the D-PTTU was able to achieve ± 0.02 ºC temperature resolution, which exceeds the design specification by a factor of three.

Description
This analysis aimed to understand how and why certain representations of fraternity and sorority life are consistently used in media texts. Throughout this thesis I analyzed various media including films, a television series, a documentary, and coverage of a news story and found that fraternity and sorority representations reinforce different social issues. Additionally, this thesis discusses how fraternities and sororities are framed in the media texts as institutions which force members to abide by larger societal norms and gender roles. Stigmas and social issues surrounding fraternity and sorority life including hazing, violence, and toxic masculinity, femininity and feminism, diversity and racism, and partying, power and misogyny are the focus of many of the media used in this study. This thesis analyzed how media use these topics to generalize representations of fraternity and sorority life members and to perpetuate normalized gender roles and dominant narratives about race and sexuality.

A significant issue in the medical field is a lack of affordable, rehabilitation practices for patients with drop foot. Drop foot is a condition where a person is unable to lift the front part of the foot. People with this condition usually swing their legs in a wide arc to avoid dragging the toes, or lift their leg higher than normal. This can cause an abnormal walking gait and force them to expend more energy than usual for mobility. This condition is usually the result of a nerve injury, brain or spinal injuries, and muscle disorders. One of the most common causes of drop foot is stroke. While there are ways for stroke survivors to live with drop foot, they do not provide free range of motion. Drop foot braces keep the foot in a stationary position with the foot lifted. They do not allow plantarflexion movement of any sort to mimic foot push off. The purpose of this experiment is to allow stroke survivors with drop foot to adjust to a normal walking gait. This experiment is also meant to allow movement while minimizing metabolic cost for the subject.

Description
This thesis project examines the stability margin for different rotor configurations for a quadcopter and compares them against each other to determine the most stable flight configuration possible. The first configuration develops a “standard” for quadcopters with each motor in a corner of a cube at a 60-degree angle from the Y-Axis. The remaining tests increase the angle five degrees per configuration, allowing the motors to get incrementally closer to each other until no longer viable. Five different tests are outlined below depicting the microscopic changes in the pitch and roll of the device. The on-board controller in the quad-copter tracks both the acceleration and gyroscopic movements of the device to obtain the stability margin of each test. Computational analysis is then used to calculate and compare the values found to determine the most stable configuration.

Description
This paper investigates Surface Mechanical Attrition Treatment (SMAT) and the influence of treatment temperature and initial sample surface finish on the corrosion resistance of 7075-T651 aluminum alloy. Ambient SMAT was performed on AA7075 samples polished to 80-grit initial surface roughness. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) tests were used to characterize the corrosion behavior of samples before and after SMAT. Electrochemical tests indicated an improved corrosion resistance after application of SMAT process. The observed improvements in corrosion properties are potentially due to microstructural changes in the material surface induced by SMAT which encouraged the formation of a passive oxide layer. Further testing and research are required to understand the corrosion related effects of cryogenic SMAT and initial-surface finish as the COVID-19 pandemic inhibited experimentation plans.

Description
This study seeks to understand the role that media coverage of the Red for Ed movement and related teachers strike in Arizona had on college students’ views toward the issues of teacher pay and education funding. I conducted a survey of 448 students from Arizona State University who were first administered a pre-test gauging their initial views on teacher pay and education funding. Participants were then divided into three groups, with the first group watching a video montage of Red for Ed media clips that contained a minute-long clip showing the average annual teacher salary level in Arizona. The second group watched an identical video montage as the first group but without the average teacher salary clip, while the third group watched an unrelated and politically insignificant video. Participants were then given the same series of questions after watching their respective stimulus videos to gauge post-test views. The results show that students exposed to media coverage that showed what teachers make on an annual basis saw significant decreases in what they thought teachers should earn and how much the state should devote to education funding in comparison to those who saw similar media coverage of Red for Ed but did not see what teachers earn. In contrast, the latter group saw no significant difference compared to those who were not exposed to any media coverage of Red for Ed, challenging the widely-touted “protest paradigm” trap often highlighted in current academic literature. Finally, the study shows that while ideology plays a role in support for higher teacher pay and willingness to raise taxes to fund education, liberal students showed no overall difference in how much they would fund education in comparison to moderate and conservative students. This study, therefore, provides insight into how interactions and portrayals in the media can influence public opinion towards teachers protests and their goals, as well as how educators can adapt to this dynamic by adopting specific protest strategies to more effectively build political and public support.

Baseball has been America’s “national pastime” since the turn of the 20th century. Until the 1960s when the National Football League, and later the National Basketball Association, began gaining popularity, Major League Baseball was the top sport in the country. The home run in baseball is one of the most exciting plays the game has to offer, and Babe Ruth was the first player to hit home runs like no one had ever seen before. By 1927, Ruth had the top five single-season home run totals, and his career high of 60 in 1927 stood as the major league record for 34 years until Roger Maris hit 61in 1961. That single-season record has since been reset by Mark McGwire, who hit 70 home runs in 1998, and Barry Bonds, who hit 73 home runs in 2001. The home run connects baseball fans in ways other aspects of the game cannot. Through those connections, the sport remains prominent in the sports world and captivates new fans every year. As the late Hall of Fame manager Earl Weaver said, “you can’t sit on a lead and run a few plays into the line and just kill clock. You’ve got to throw the ball over the damn plate and give the other man his chance. That’s why baseball is the greatest game of them all.”

An understanding of aerodynamics is crucial for automobile performance and efficiency. There are many types of “add-on” aerodynamic devices for cars including wings, splitters, and vortex generators. While these have been studied extensively, rear spoilers have not, and their effects are not as widely known. A Computational Fluid Dynamics (CFD) and wind tunnel study was performed to study the effects of spoilers on vehicle aerodynamics and performance. Vehicle aerodynamics is geometry dependent, meaning what applies to one car may or may not apply on another. So, the Scion FRS was chosen as the test vehicle because it is has the “classic” sports car configuration with a long hood, short rear, and 2+2 passenger cabin while also being widely sold with a plethora of aftermarket aerodynamic modifications available. Due to computing and licensing restrictions, only a 2D CFD simulation was performed in ANSYS Fluent 19.1. A surface model of the centerline of the car was created in SolidWorks and imported into ANSYS, where the domain was created. A mesh convergence study was run to determine the optimum mesh size, and Realizable k-epsilon was the chosen physics model. The wind tunnel lacked equipment to record quantifiable data, so the wind tunnel was utilized for flow visualization on a 1/24 scale car model to compare with the CFD.
0° spoilers reduced the wake area behind the car, decreasing pressure drag but also decreasing underbody flow, causing a reduction in drag and downforce. Angled spoilers increased the wake area behind the car, increasing pressure drag but also increasing underbody flow, causing an increase in drag and downforce. Longer spoilers increased these effects compared to shorter spoilers, and short spoilers at different angles did not create significantly different effects. 0° spoilers would be best suited for cases that prioritize fuel economy or straight-line acceleration and speed due to the drag reduction, while angled spoilers would be best suited for cars requiring downforce. The angle and length of spoiler would depend on the downforce needed, which is dependent on the track.
