Recruitment of students in engineering programs is a critical endeavor for universities striving to thrive in an increasingly competitive landscape. This master’s thesis investigates the effectiveness of utilizing an ASU-inspired Mandalorian armor set as a recruitment prop at engineering recruitment events. The research questions posed in this study delve into the behavioral response of event attendees and evaluate the prop's effectiveness in generating interest and initiating interactions with ASU recruiting staff. Drawing on a combination of observational data, thematic analysis, and insights from the literature review, this study evaluates the prop's impact on booth traffic, attendee engagement, and overall recruitment efforts. The observational data collected from two recruitment events on March 22, 2024, and March 24, 2024, revealed fluctuations in attendee engagement with the prop, with substantial visitor traffic observed on March 22, 2024, compared to March 24, 2024. The thematic analysis provided deeper insights into the prop's role as a conversation starter and attraction for both adults and children, highlighting its ability to spark curiosity and inquiries about its significance and association with ASU and engineering programs. The literature review supported these findings, offering insights into the dynamics of college choice processes and the strategic deployment of marketing practices in higher education recruitment. Concepts from studies by Han (2014), Rogers et al. (2010), Muller et al. (2010), and Brignull & Rogers (2003) informed the design attribution, booth interaction strategies, and logistical considerations associated with the prop's deployment.

The CNC mill is a highly valuable tool for engineering design, allowing for the creation of precise and complex metal parts. However, due to their high cost, many engineers do not have access to these machines until they enter industry, limiting the knowledge and experience of engineering students. This also restricts the level of engineering design they can participate in as they are limited to lower strength materials and processes. To expand the possibilities for engineering students, hobbyists, and small businesses, we created a reliable and affordable desktop CNC mill. Our machine is capable of cutting non-ferrous metals such as aluminum with 70μm repeatable part precision and be compatible with coolant and vacuum systems.

Significant efforts are underway by engineering organizations to diversify their workforce. However, research findings on workplace diversity are mixed, with insufficient clarity into what makes heterogeneous work environments successful. Acknowledging the role of individual behavior in building diverse workplaces that are cohesive and productive, researchers have called for more theory-based investigation into individuals’ workplace behaviors and their determinants. This three-part study bridges the gap within an engineering context by leveraging Berry's acculturation framework (Berry, 1972, 2005) from cross-cultural psychology to examine the factors influencing engineers’ acculturation behaviors in workplaces. Acculturation refers to the process by which individuals adjust to people different from themselves in their daily interactions (Berry, 1972, 2005). Based on Berry’s framework, the study postulates four acculturation attitudes and behaviors for engineers—Integration, Assimilation, Separation, and Marginalization. Acculturation attitudes are based on acculturation preferences, such as the importance an individual places on retaining individual values and the importance an individual places on receiving acceptance from coworkers. These acculturation attitudes and perceived acceptance together influence behaviors. The first study designed and validated an instrument to measure engineers’ acculturation preferences, acculturation behaviors, and perceived acceptance from coworkers. The results provided complete to partial support for the expected correlations among factors. The second study conducted cluster and Chi-square analyses focusing on the two acculturation preferences. The results revealed four clusters corresponding to Berry’s acculturation attitudes and revealed findings, such as women’s preference for Integration attitude over men’s. The third study used a path model to gain insight into gender differences in engineers’ acculturation behaviors and revealed acceptance as a crucial factor. The results quantitatively substantiated prior findings, namely, that women engineers prefer Assimilation and Separation behaviors more and Integration behavior less mediated by factors related to acceptance. The developed instrument and study findings offer researchers another lens to study organizations’ diversification efforts, along with other personal and contextual factors. The study findings could also help engineering organizations recruit employees with acculturation attitudes favorable to the organization’s diversity goals and design trainings that highlight the importance of coworker acceptance. Such interventions would facilitate the creation of more diverse work environments.

With the recent focus of attention towards remote work and mobile computing, the possibility of taking a powerful workstation wherever needed is enticing. However, even emerging laptops today struggle to compete with desktops in terms of cost, maintenance, and future upgrades. The price point of a powerful laptop is considerably higher compared to an equally powerful desktop computer, and most laptops are manufactured in a way that makes upgrading parts of the machine difficult or impossible, forcing a complete purchase in the event of failure or a component needing an upgrade. In the case where someone already owns a desktop computer and must be mobile, instead of needing to purchase a second device at full price, it may be possible to develop a low-cost computer that has just enough power to connect to the existing desktop and run all processing there, using the mobile device only as a user interface. This thesis will explore the development of a custom PCB that utilizes a Raspberry Pi Computer Module 4, as well as the development of a fork of the Open Source project Moonlight to stream a host machine's screen to a remote client. This implementation will be compared against other existing remote desktop solutions to analyze it's performance and quality.

Embedded software is different in many aspects to traditional software; as such, a software developer may face issues when attempting to transition from traditional to embedded software development. This thesis explores providing feedback and applying optimizations at the source code level of embedded software. The aim is to measure the impact of these optimizations on teaching embedded software design principles, as well as assessing the relative success of each optimization in terms of a variety of metrics. There are many considerations when altering code and is a known limitation imposed by most software optimization schemes. By applying optimizations at the source level, the aim is to demonstrate what the optimizations do and how they provide value to the resulting software. In order to fulfill these goals, the Embedded C Source Optimizer has been developed, which is used to import and export code, select which optimizations are applied, and provide feedback to the end user. This utility abstracts away the lower level operations performed by each optimization, while conveying the resulting changes to the end user. Since embedded systems are generally quite limited compared to modern computers, someone transitioning from traditional software design to embedded software may find it challenging to understand how to overcome these limitations. Clearly conveying means to improve a naive implementation of an embedded program aids through demonstrating what changes need to be made to satisfy embedded design rules. The optimizations which the utility can apply range from simple replacement operations to more complex applications of implicit utilization of built-in hardware peripherals on supported microcontrollers. Each optimization comes with its own set of considerations, risks, and potential level of improvement to the resulting code. These optimization options are evaluated by comparing embedded software before and after each option is applied through a variety of metrics, allowing the relative success of each to be determined as effectively as possible. The end goal for this utility is to aid in crossing the hurdle from traditional software to embedded software in a comprehensive and educational manner, with the provided optimization options acting as an avenue for teaching embedded concepts.

The purpose of this creative project was to create a stereo sound system in a unique medium. As a team, we decided to integrate a Tesla Coil with a bluetooth audio source. These high frequency, high voltage systems can be configured to emit their electrical discharge in a manner that resembles playing tunes. Originally the idea was to split the audio into left and right, then to further segregate the signals to have a treble, mid, and base emitter for each side. Due to time, budget, and scope constraints, we decided to complete the project with only two coils.<br/><br/>For this project, the team decided to use a solid-state coil kit. This kit was purchased from OneTelsa and would help ensure everyone’s safety and the project’s success. The team developed our own interrupting or driving circuit through reverse-engineering the interrupter provided by oneTesla and discussing with other engineers. The custom interpreter was controlled by the PSoC5 LP and communicated with an audio source through the DFRobot Bluetooth module. Utilizing the left and right audio signals it can drive the two Tesla Coils in stereo to play the music.

This graduate thesis explains and discusses the background, methods, limitations, and future work of developing a low-budget, variable-length, Arduino-based robotics professional development program (PDP) for middle school or high school classrooms. This graduate thesis builds on prior undergraduate thesis work and conclusions. The main conclusions from the undergraduate thesis work focused on reaching a larger teacher population along with providing a more robust robot design and construction. The end goal of this graduate thesis is to develop a PDP that reaches multiple teachers, involves a more robust robot design, and lasts beyond this developmental year. There have been many similar research studies and PDPs that have been tested and analyzed but do not fit the requirements of this graduate thesis. These programs provide some guidance in the creation of a new PDP. The overall method of the graduate thesis comes in four main phases: 1) setup, 2) pre-PDP phase, 3) PDP phase, and 4) post PDP phase. The setup focused primarily on funding, IRB approval, research, timeline development, and research question creation. The pre-PDP phase focused primarily on the development of new tailored-to-teacher content, a more robust robot design, and recruitment of participants. The PDP phase primarily focused on how the teachers perform and participate in the PDP. Lastly, the post PDP phase involved data analysis along with a resource development plan. The last post-PDP step is to consolidate all of the findings in a clear, concise, and coherent format for future work.

The purpose of this paper is to develop an understanding of Navajo students' perspectives on how engineering can be used to improve life in their own communities on the Navajo reservation. Branching off an existing study that aims to develop a culturally-contextualized engineering design curriculum for middle schools in the Navajo Nation, this research focuses on a curriculum module entitled, "Future Chapter Presidents". This module is inspired by the Future City Competition where middle school students are tasked with imagining a better future. To make "Future Chapter Presidents" more culturally-relevant, students are instead tasked with proposing solutions that will improve life on the reservation. This module emphasizes engineering design alongside teaching Navajo Nation government standards by having students in the class run for a position in their local government. Students are prompted with creating a campaign poster that showcases their proposed solutions directed at their own communities. In order to analyze students' perspectives and understanding of how engineering can be used to improve life on the reservation, thematic analysis is used to study each individual poster. Meanwhile, because the researchers conducting this study are not Navajo, Tribal Critical Race Theory (Brayboy, 2006) was applied to ensure that the content of the posters are interpreted from an Indigenous lens. The results of this study can be used to inform future curriculum development for engineering design modules in the Navajo Nation and expand upon existing literature that provides understanding of how Navajo students experience and understand engineering in the context of their culture.
