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.

My thesis is on the subject of mentoring. I researched the benefits and the styles of programs available and then used my research to create a survey to give to IDSA national members to see what they believe would make a good mentoring program. From there I tried to improve the current ASU IDSA mentoring program.

Freewheelin': The American Counterculture in Museums is the first study to explore American museums that collect artifacts from the counterculture era at length. Examining institutions whose specialized collections and histories represent the recent, dynamic social movements of the mid-twentieth century begets particular institutional challenges and extraordinary opportunities; both factors causing the evolution of some American history museums into premier social history centers. I have focused on four institutions for research: the Beat Museum, the GLBT History Museum, the Rock and Roll Hall of Fame, and the Museum of Sex. The analysis of each organization contains a brief account of the history they strive to preserve, a case study of their professional operations, and objective recommendations. Ultimately through researching the four selected institutions and museum studies at large, it was determined that certain collective features are propelling a paradigm shift in modern American history museums.

Capstone project, I began developing an animated series called Legends of Gaia. The show follows a small group of people of mixed ages and backgrounds, as they travel across the world trying to stop the Galliean Empire, a technologically booming western power that has begun fighting a war for world domination. The purpose of this paper is to better explain the origins and inspirations of the mythology of my series, as well as the major two supernatural characters of my series, and the general geography (both physical and metaphysical) of the series. When first developing this series, I looked into the works of Joseph Campbell, as he wrote the book(s) on mythology in many ways. His most famous writings are probably the Hero's Journey and the Monomyth, the basic outline of the journey that most heroes go through, from the call ordinary world, to the call of the adventure, all the way to the hero returning (Campbell 211). Many classic examples of story telling follow the pattern Campbell outlined, and my work is no exception. However, I did not want my series to be a beat for beat retread of the Hero's Journey, and so some parts, such as the Refusal of the Call, when the hero rejects the adventure and befalls a tragedy, were skipped, while others, such as the resurrection, were realized in different ways. Using the Resurrection as an example, in my series the main female character, Diana is reborn twice throughout the series. Once in the final battle with the main villain into her true, goddess form, and the other when her battles are over, and she is reborn in her mortal form permanently.

De Oriendo is a project devoted to a better understanding of the word "original" as it pertains to musical composition. It began as a way for me to try to tackle a twofold fascination that has been with me for the duration of my time at ASU, though I have not always been aware of it. The first half of this fascination is an enduring interest in tracing borrowed material used by composers and other artists throughout history. It seems that almost every research project I have undertaken in the last four years has had something to do with this concept. Scholars like Winton Dean, J. Peter Burkholder, and Sigmund Spaeth have spent parts of their careers charting out the genealogy of historical compositions, uncovering reused melodies and harmonic progressions in the process; the cases of it are countless, even among the most identifiable composers and songwriters. Since there is scholarship clearly demonstrating secondhand ideas in music, it becomes problematic to assume that the word "original" simply describes something completely new, that is, something that does not use material heard or seen before. The second half is more of a personal ambition: I thought that if I truly knew what composers and critics meant when they labeled a piece or an artist as original, then I could somehow find a way to achieve this distinction in my own attempts at composition and avoid that uninteresting, derivative sound I have always feared.

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.

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.

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.
