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.

With as rapid a growth that Esports has had and its current introduction to the public mainstream, there is yet to be sufficient studies and research compiled to fully develop the profile of an Esport consumer. While companies such as Neilson and others have begun scratching the surface of the Esport community, there is much that is relatively unknown. Consumer behavior patterns of traditional sports has been defined for years, however as the billion dollar a year industry that Esports is, Esport consumer behavior is still taking shape. This thesis will attempt to build upon previous studies conducted by former Arizona State University students to continue to define the Esport consumer. Through quantitative research conducted via an online survey consisting of demographic, behavioral, and psychographic questions, the stereotype of an Esport consumer will be dissolved to reveal their true nature. This study will prove to be an iteration among the previous research by -<br/>• Developing a functional segmentation of Esport consumers, which will allow for marketers within the industry to better understand their audience in their attempts to persuade/incentivize<br/>• Understanding and dissecting the scale of influence that content creators (those who play Esports for the purpose of entertaining through various platforms) and competitive Esport athletes have on certain segmentations of consumers<br/>• Discovering the impact the COVID-19 pandemic has had on certain segmentations in regards to their time spent playing themselves<br/><br/> After compiling results from this questionnaire, marketers that are both endemic and non-endemic brands seeking to partner within the Esports space will have a better understanding of their audience and how to connect with them.

In this essay, I set out to explore and analyze how Shirley Jackson’s The Haunting of Hill House, and the character of Eleanor Vance in particular, disrupts and redefines the traditional conventions of the Female Gothic within the context of the 20th century. I utilize Tania Modleski's gendering of Freud's theory of psychoanalysis in her exploration of the ‘Female Uncanny,’ arguing that the source of the Uncanny in the Female Gothic can be found in the "fear of being lost in the mother." I argue that Jackson's complex personal life, including her fraught relationship with her mother and her difficult marriage with literary critic Edgar Hyman, color her fiction and the primary motivations of her protagonist, Eleanor Vance. I also outline the traditional structure of the Gothic novel and the heroine's journey. With the necessary context provided, I then explain how Eleanor Vance’s character rejects these Gothic traditions and ushers in a new era of Female Gothic fiction.

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.

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.
