Description
In this project, the use of deep neural networks for the process of selecting actions to execute within an environment to achieve a goal is explored. Scenarios like this are common in crafting based games such as Terraria or Minecraft. Goals in these environments have recursive sub-goal dependencies which form a dependency tree. An agent operating within these environments have access to low amounts of data about the environment before interacting with it, so it is crucial that this agent is able to effectively utilize a tree of dependencies and its environmental surroundings to make judgements about which sub-goals are most efficient to pursue at any point in time. A successful agent aims to minimizes cost when completing a given goal. A deep neural network in combination with Q-learning techniques was employed to act as the agent in this environment. This agent consistently performed better than agents using alternate models (models that used dependency tree heuristics or human-like approaches to make sub-goal oriented choices), with an average performance advantage of 33.86% (with a standard deviation of 14.69%) over the best alternate agent. This shows that machine learning techniques can be consistently employed to make goal-oriented choices within an environment with recursive sub-goal dependencies and low amounts of pre-known information.

Young adults do not know basic emergency preparedness skills. Although there are materials out there such as printed and online materials form Center for Disease Control, it is unlikely that college-age people will take the time to read them. Some individuals have addressed the issue of young adults not wanting to read materials by creating a fun interactive game in the San Francisco area, but since the game must be played in person, a solution like that can only reach so far. Studies suggest that virtual worlds are effective in teaching people new skills, so I have created a virtual world that will teach people basic emergency preparedness skills in a way that is memorable and appealing to a college-age audience. The logic used to teach players the concepts of emergency preparedness is case-based reasoning. Case-based reasoning is the process of solving new problems by remembering similar solutions in the past. By creating a simulation emergency situation in a virtual world, young adults are more likely to know what to do in the case of an actual emergency.

Description
Makers are those who enjoy creating things and learning new skills, as well as interacting within a connected community (Doughtery, 2012). Through the analysis of Makers as part of a larger study (Jordan & Lande, 2013) a researcher had noticed the emergence of leadership traits within the Maker community (Oplinger, Jordan, and Lande, 2015). The National Academy of Engineering has determined that leadership is a key quality for the engineer of the future (Clough, 2004). The Engineering Accreditation Commission has determined several necessary outcomes for engineering students that coincide with leadership roles (Engineering Accreditation Commission, 2012). Proactiveness, confidence, motivation, communication, coaching will be important skills for engineers so that they can effectively lead teams, adjust to change, and synthesize (Ahn, Cox, London, Cekic, and Zhu, 2014). In National Academy of Engineering's The Engineer of 2020 (Clough, 2004) future engineers are expected to be in position to influence "in the making of public policy and in the administration of government and industry." The Maker community offers a broad spectrum of individuals engaged in informal engineering and tinkering activities across multiple pathways (Foster, Wigner, Lande, and Jordan, 2015). This study explores leadership using a theoretical framework of competing values (Quinn, 1988) (Zafft, Adams, and Matkin, 2009) including relating to people, managing processes, leading change, and producing results. The study relies upon artifact elicitation (based on photo elicitation (Harper, 2002)) with 40 of these Makers at four Maker Faires in the United States. The artifact elicitation interviews were conducted at the Maker Faires in front of participants' inventions, where the Makers were asked to describe the invention and the process behind it. Using a theoretical framework of competing values (Quinn, 1988) (Quinn, Faerman, Thompson, and McGrath, 1990) and through parallel inductive-deductive analysis, the emergent themes among our sample of Makers include that they express leadership qualities of (1) innovators \u2014 they utilize different skillsets to develop unique products and solutions; (2) monitors \u2014 they evaluate projects and respond to results; (3) directors \u2014 they set goals and expectations of their projects and processes; and (4) producers \u2014 they are determined and possess a personal drive. From the findings a call to action is made on implementing leadership lessons in the engineering classroom.

Description
As robotics technology advances, robots are being created for use in situations where they collaborate with humans on complex tasks. For this to be safe and successful, it is important to understand what causes humans to trust robots more or less during a collaborative task. This research project aims to investigate human-robot trust through a collaborative game of logic that can be played with a human and a robot together. This thesis details the development of a game of logic that could be used for this purpose. The game of logic is based upon a popular game in AI research called ‘Wumpus World’. The original Wumpus World game was a low-interactivity game to be played by humans alone. In this project, the Wumpus World game is modified for a high degree of interactivity with a human player, while also allowing the game to be played simultaneously by an AI algorithm.

Description
Adaptive expertise is a model of learning that posits two dimensions of development: efficiency and innovation. The mindset of an adaptive expert will serve any engineer by drawing upon diverse experiences to develop novel solutions to problems. Their mindset is based in lifelong learning, characterized by applying past experience to current design challenges. Solution design requires a process, and a breadth of experience is among the adaptive expert's greatest tools in identifying the approach to take in an unfamiliar situation. The fluidity and agility of their mind allows them to work effectively throughout their career in technical design, as the situation of an engineer's design work can vary drastically over the course of time. This paper describes a study on an innovative junior-level electrical and robotic systems project course taught at a large southwestern university that encourages students to develop adaptive expertise in the context of real-world design projects. By fabricating prototypes, students learn strategies for troubleshooting and technical design, and iterations of the part demand reflection on previous design thinking. This study seeks to answer the following research questions: (1) How does user-centered design stimulate abstractive design thinking? (2) How does fabrication of prototypes stimulate active design thinking? And (3) How is the classroom culture enabling engineering design in the optimal adaptability corridor? Critical incident interviews were conducted with stakeholders in the course, and a thematic analysis of the transcripts conducted. Results show that this project-based curriculum fosters adaptive expertise by stimulating both abstractive and active design thinking. This provides a framework for practicing adaptive design thinking in classrooms. Disseminating these findings to curriculum designers will encourage more engaging, effective classes that graduate adaptive experts.

Description
Effective communication and engineering are not a natural pairing. The incongruence is because engineering students are focused on making, designing and analyzing. Since these are the core functions of the field there is not a direct focus on developing communication skills. This honors thesis explores the role and expectations for student engineers within the undergraduate engineering education experience to present and communicate ideas. The researchers interviewed faculty about their perspective on students' abilities with respect to their presentation skills to inform the design of a workshop series of interventions intended to make engineering students better communicators.

Optical Communications are at a high point of interest by the space engineering community. After successful projects like the Lunar Laser Communications Demonstration (LLCD), NASA has become interested in augmenting their current Deep Space Network (DSN) with optical communication links. One such link is Deep Space Optical Communications (DSOC) which will be launching with the Psyche mission. To gain a full understanding of the advantages of this network, this thesis will go over the history and benefits of optical communications both on Earth and in space. This thesis will then go in depth on NASAs DSOC project through an algorithmic implementation of the communications channel.

Description
Class instructors at Arizona State University monitor students’ attendance for classes in which attendance is either mandatory or encouraged. Class monitoring can be done using traditional systems such as sign sheets and roll calls. From my initial observations while attending a class which utilized a sign sheet for class attendance monitoring, I thought the process took long and was inefficient. As a result, I created an automated system that would replace the traditional systems and improve the class monitoring process. Thus, this study aims to determine whether the automated system reduced the time it takes to monitor class attendance, and whether it was efficient.
To examine the above question, the automated system was deployed to 2 classes at Arizona State University. Additionally, surveys were distributed to 2 instructors and 33 students and they were asked to respond to questions relating to class attendance and the monitoring systems which were being used alternatively with the newly-created automated system. Analysis of the responses demonstrated that use of an automated system reduced the time it takes students to mark their presence, and thus increase the time used for other class activities. The results also indicate that the design of the automated system affects the overall time it takes to monitor attendance. On this basis, it is recommended that instructors utilize an automated system to monitor class attendance. Further research is needed to study the time it takes instructors to set up different monitoring systems in order to ascertain that an automated system reduces the overall time it takes to monitor attendance compared to other traditionally used systems.

The spread of fake news (rumors) has been a growing problem on the internet in the past few years due to the increase of social media services. People share fake news articles on social media sometimes without knowing that those articles contain false information. Not knowing whether an article is fake or real is a problem because it causes social media news to lose credibility. Prior research on fake news has focused on how to detect fake news, but efforts towards controlling fake news articles on the internet are still facing challenges. Some of these challenges include; it is hard to collect large sets of fake news data, it is hard to collect locations of people who are spreading fake news, and it is difficult to study the geographic distribution of fake news. To address these challenges, I am examining how fake news spreads in the United States (US) by developing a geographic visualization system for misinformation. I am collecting a set of fake news articles from a website called snopes.com. After collecting these articles I am extracting the keywords from each article and storing them in a file. I then use the stored keywords to search on Twitter in order to find out the locations of users who spread the rumors. Finally, I mark those locations on a map in order to show the geographic distribution of fake news. Having access to large sets of fake news data, knowing the locations of people who are spreading fake news, and being able to understand the geographic distribution of fake news will help in the efforts towards addressing the fake news problem on the internet by providing target areas.

Description
Parents in STEM careers are more apt to guide their kids towards STEM careers (Sherburne-Michigan, 2017). There are STEM programs and classes for students who are interested in related fields, but the conundrum is that students need to be interested in order to choose to participate. The goal of this creative project was to introduce engineering concepts in a high school class to reveal and investigate the ways in which engineering concepts can be successfully introduced to a larger student populace to increase interest in engineering programs, courses, and degrees. A lesson plan and corresponding materials - including circuit kits and a simulated ball launching station with graphical display - were made to accomplish this goal. Throughout the lesson students were asked to (1) use given materials to accomplish a goal, (2) predict outcomes based on conceptual understanding and mathematical calculations, (3) test predictions, (4) record data, and (5) analyze data to generate results. The students first created a simple circuit to understand the circuit components and learn general electrical engineering concepts. A simple light dimmer circuit let students demonstrate understanding of electrical concepts (e.g., voltage, current resistance) before using the circuit to a simulated motor in order to launch a ball. The students were then asked to predict the time and height of a ball launched with various settings of their control circuit. The students were able to test their theories with the simulated launcher test set up shown in Figure 25 and collect data to create a parabolic height versus time graph. Based on the measured graph, the students were able to record their results and compare calculated values to real-world measured values. The results of the study suggest ways to introduce students to engineering while developing hands-on concept modeling of projectile motion and circuit design in math classrooms. Additionally, this lesson identifies a rich topic for teachers and STEM education researchers to explore lesson plans with interdisciplinary connections to engineering. This report will include the inspiration for the product, related work, iterative design process, and the final design. This information will be followed by user feedback, a project reflection, and lessons learned. The report will conclude with a summary and a discussion of future work.
