As robots become more prevalent, the need is growing for efficient yet stable control systems for applications with humans in the loop. As such, it is a challenge for scientists and engineers to develop robust and agile systems that are capable of detecting instability in teleoperated systems. Despite how much research has been done to characterize the spatiotemporal parameters of human arm motions for reaching and gasping, not much has been done to characterize the behavior of human arm motion in response to control errors in a system. The scope of this investigation is to investigate human corrective actions in response to error in an anthropomorphic teleoperated robot limb. Characterizing human corrective actions contributes to the development of control strategies that are capable of mitigating potential instabilities inherent in human-machine control interfaces. Characterization of human corrective actions requires the simulation of a teleoperated anthropomorphic armature and the comparison of a human subject's arm kinematics, in response to error, against the human arm kinematics without error. This was achieved using OpenGL software to simulate a teleoperated robot arm and an NDI motion tracking system to acquire the subject's arm position and orientation. Error was intermittently and programmatically introduced to the virtual robot's joints as the subject attempted to reach for several targets located around the arm. The comparison of error free human arm kinematics to error prone human arm kinematics revealed an addition of a bell shaped velocity peak into the human subject's tangential velocity profile. The size, extent, and location of the additional velocity peak depended on target location and join angle error. Some joint angle and target location combinations do not produce an additional peak but simply maintain the end effector velocity at a low value until the target is reached. Additional joint angle error parameters and degrees of freedom are needed to continue this investigation.

Long distance travel around the globe can potentially be revolutionized with the use of an intercontinental rocket that uses low earth orbit as its medium. This transport system can increase growth in many new businesses like tourism travel between the continents. This research evaluates the technical and non-technical possibilities of using a double-stage reusable rocket, where the second stage is also a reusable, rocket-powered passenger vehicle using a low earth orbit space journey with a stabilized re-entry method that ensures passenger comfortability. A potential network of spaceports spanning the globe is postulated within a range of 4,000 km to 8,000 km(2,160 nm to 4,320 nm) of each other, and each located within an hour by any other means of ground transport to population hubs greater than four million. This will help further connect the world as the journey from one major city to another would take at most an hour, and no point on the habited continents would be more than 4,000 km(2,160 nm) from a spaceport. It is assumed that the costs of an international first class flight ticket are in the thousands of dollars range showing how there is a potential market for this type of travel network. The reasoning and analysis, through a literature review, for an intercontinental rocket vehicle is presented along with the various aspects of the possibility of this kind of travel network coming to fruition in the near future.

Students from the Founder’s Lab at ASU created Equalitree, a company whose main focus is bringing together fans, student-athletes, coaches, and executive staff. In developing the company, the founders looked at various data points from the NCAA about what is already being done to increase diversity and inclusion. After finding staggering statistics about the state of diversity, the founders began to create ‘Equalitree’. A consulting agency tackling diversity and inclusion. The goal is to increase diversity and inclusion within sports organizations through a series of educational events, social campaigns, and dialogues. In researching the effectiveness of this business model, the founders hosted a week of events. The first event was a dialogue, in which attendees were presented with statistics of diversity within college sports, what is being done on college campuses to bridge gaps and open dialogues, and even held a discussion. For the second event, the founders hosted Keynote Speaker, former NFL player L.J. Shelton, to speak on his experiences within college sports and the NFL. Overall, Equalitree received highly rated reviews and feedback from attendees about the events and the effectiveness.

Titanium has been and continues to be a popular metal across any form of manufacturing and production because of its extremely favorable properties. In important circumstances, it finds itself outclassing many metals by being lighter and less dense than comparably strong metals like steel. Relative to other metals it has a noteworthy corrosion resistance as it is stable when it oxidizes, and due to the inert nature of the metal, it is famously hypoallergenic and as a result used in a great deal of aviation and medical fields, including being used to produce replacement joints, with the notable limitation of the material being its cost of manufacturing. Among the variants of the metal and alloys used, Ti6Al4V alloy is famous for being the most reliable and popular combination for electron beam manufacturing(EBM) as a method of additive manufacturing. <br/>Developed by the Swedish Arcam, AB, EBM is one of the more recent methods of additive manufacturing, and is notable for its lack of waste by combining most of the material into the intended product due to its precision. This method, much like the titanium it is used to print in this case, is limited mostly by time and value of production. <br/>For this thesis, nine different simulations of a dogbone model were generated and analyzed in Ansys APDL using finite element analysis at various temperature and print conditions to create a theoretical model based on experimentally produced values.

Whispers from Above is a creative project that aims to normalize the conversation and validate the emotional experience of grief, through the use of art therapies. Art therapy can be expressive in which someone creates their own work, such as visual art, poetry, performance, music, movement, etc. Art therapy can also be receptive in which someone analyzes and understands someone else's artwork. This project was released on SoundCloud in order to make grief resources more accessible to all and to build an online community.<br/><br/>Whispers from Above worked with twelve poets, fifteen artists, six different interviewees, and multiple musicians to create a month of grief support. The finale piece of Whispers from Above was devised from the twenty-nine poems used within this month-long healing journey. All the individual poems were woven into a single devised poem to be presented as the final piece symbolizing that no one is alone in grief.<br/><br/>Whispers from Above is creative community exploration of grief, loss, and death in which we hope contributors, and listeners find solace and support. This series will exist on SoundCloud after March 27th, 2021 with a monthly release of a poem or interview accompanied by art, and music.

Digital learning tools have become ubiquitous in virtual and in person classrooms as teachers found creative ways to engage students during the COVID 19 pandemic. Even before the pandemic and widespread remote learning, however, digital learning tools were increasingly common and a typical part of many classrooms. While all digital learning tools are worthy of study, math digital learning tools (MDLTs) designed for K - 8th grade in particular raise questions of efficacy and usefulness for classrooms. This paper shows that MDLTs are an effective tool to raise students’ math achievement across K - 8th grade, and that time spent on MDLTs can lead to better understanding of a topic than traditional, teacher led instruction. However, if the MDLT is being delivered in a language the student is not familiar with, that student will not be able to benefit from MDLTs in the way other students do. This is also true of students who receive Special Education services. Additionally, higher quality MDLTs that provide feedback that attaches meaning to students’ work creates a better learning environment for students than one with simpler feedback. Based on my experiences with student teaching this year and using the popular MDLT IXL frequently, I recommend that MDLTs not just be used for independent practice time, but for whole class, problem solving sessions where students have to use mathematical thinking in new content areas. This will build deeper conceptual learning and a greater sense of achievement in students.

The past two and a half semesters have been extremely difficult for college students. Due to the COVID-19 pandemic, student motivation has been slipping. I felt my own productivity slowly diminishing shortly after March 2020, and a number of students that I have spoken with share a similar mentality. In addition, the social lives of students have taken a toll. Social distancing, event cancellations and online classes have led to a serious lack of social interaction with their peers. I felt as though the theatre community, in particular, was suffering, because of how much of our lives are centered around social interaction. Not only is social interaction recreational for us theatre students, but it’s integral for our careers as well. We are very conditioned to getting together multiple times a week just to experience emotion with each other, and this was all taken away very abruptly in March 2020. The remaining theatrical events last season were cancelled, and the events this season were mostly moved to an online setting. I began to think that the theatre community at ASU needed some way to stay connected despite these unfortunate circumstances, and that is when I found out about Alpha Psi Omega. Alpha Psi Omega is a National Theatre Honors Society which used to have a chapter here at ASU, so I took it upon myself to reactivate the chapter.

This thesis project has been conducted in accordance with The Founder’s Lab initiative which is sponsored by the W. P. Carey School of Business. This program groups three students together and tasks them with creating a business idea, conducting the necessary research to bring the concept to life, and exploring different aspects of business, with the end goal of gaining traction. The product we were given to work through this process with was Hot Head, an engineering capstone project concept. The Hot Head product is a sustainable and innovative solution to the water waste issue we find is very prominent in the United States. In order to bring the Hot Head idea to life, we were tasked with doing research on topics ranging from the Hot Head life cycle to finding plausible personas who may have an interest in the Hot Head product. This paper outlines the journey to gaining traction via a marketing campaign and exposure of our brand on several platforms, with a specific interest in website traffic. Our research scope comes from mainly primary sources like gathering opinions of potential buyers by sending out surveys and hosting focus groups. The paper concludes with some possible future steps that could be taken if this project were to be continued.
