Description
Research on human grasp typically involves the grasp of objects designed for the study of fingertip forces. Instrumented objects for such studies have often been designed for the simulation of functional tasks, such as feeding oneself, or for rigidity such that the objects do not deform when grasped. The goal of this thesis was to design a collapsible, instrumented object to study grasp of breakable objects. Such an object would enable experiments on human grip responses to unexpected finger-object events as well as anticipatory mechanisms once object fragility has been observed. The collapsible object was designed to be modular to allow for properties such as friction and breaking force to be altered. The instrumented object could be used to study both human and artificial grasp.

Description
The generation of walking motion is one of the most vital functions of the human body because it allows us to be mobile in our environment. Unfortunately, numerous individuals suffer from gait impairment as a result of debilitating conditions like stroke, resulting in a serious loss of mobility. Our understanding of human gait is limited by the amount of research we conduct in relation to human walking mechanisms and their characteristics. In order to better understand these characteristics and the systems involved in the generation of human gait, it is necessary to increase the depth and range of research pertaining to walking motion. Specifically, there has been a lack of investigation into a particular area of human gait research that could potentially yield interesting conclusions about gait rehabilitation, which is the effect of surface stiffness on human gait. In order to investigate this idea, a number of studies have been conducted using experimental devices that focus on changing surface stiffness; however, these systems lack certain functionality that would be useful in an experimental scenario. To solve this problem and to investigate the effect of surface stiffness further, a system has been developed called the Variable Stiffness Treadmill system (VST). This treadmill system is a unique investigative tool that allows for the active control of surface stiffness. What is novel about this system is its ability to change the stiffness of the surface quickly, accurately, during the gait cycle, and throughout a large range of possible stiffness values. This type of functionality in an experimental system has never been implemented and constitutes a tremendous opportunity for valuable gait research in regard to the influence of surface stiffness. In this work, the design, development, and implementation of the Variable Stiffness Treadmill system is presented and discussed along with preliminary experimentation. The results from characterization testing demonstrate highly accurate stiffness control and excellent response characteristics for specific configurations. Initial indications from human experimental trials in relation to quantifiable effects from surface stiffness variation using the Variable Stiffness Treadmill system are encouraging.

Description
Most daily living tasks consist of pairing a series of sequential movements, e.g., reaching to a cup, grabbing the cup, lifting and returning the cup to your mouth. The process by which we control and mediate the smooth progression of these tasks is not well understood. One method which we can use to further evaluate these motions is known as Startle Evoked Movements (SEM). SEM is an established technique to probe the motor learning and planning processes by detecting muscle activation of the sternocleidomastoid muscles of the neck prior to 120ms after a startling stimulus is presented. If activation of these muscles was detected following a stimulus in the 120ms window, the movement is classified as Startle+ whereas if no sternocleidomastoid activation is detected after a stimulus in the allotted time the movement is considered Startle-. For a movement to be considered SEM, the activation of movements for Startle+ trials must be faster than the activation of Startle- trials. The objective of this study was to evaluate the effect that expertise has on sequential movements as well as determining if startle can distinguish when the consolidation of actions, known as chunking, has occurred. We hypothesized that SEM could distinguish words that were solidified or chunked. Specifically, SEM would be present when expert typists were asked to type a common word but not during uncommon letter combinations. The results from this study indicated that the only word that was susceptible to SEM, where Startle+ trials were initiated faster than Startle-, was an uncommon task "HET" while the common words "AND" and "THE" were not. Additionally, the evaluation of the differences between each keystroke for common and uncommon words showed that Startle was unable to distinguish differences in motor chunking between Startle+ and Startle- trials. Explanations into why these results were observed could be related to hand dominance in expert typists. No proper research has been conducted to evaluate the susceptibility of the non-dominant hand's fingers to SEM, and the results of future studies into this as well as the results from this study can impact our understanding of sequential movements.

Description
Electromyography (EMG) and Electroencephalography (EEG) are techniques used to detect electrical activity produced by the human body. EMG detects electrical activity in the skeletal muscles, while EEG detects electrical activity from the scalp. The purpose of this study is to capture different types of EMG and EEG signals and to determine if the signals can be distinguished between each other and processed into output signals to trigger events in prosthetics. Results from the study suggest that the PSD estimates can be used to compare signals that have significant differences such as the wrist, scalp, and fingers, but it cannot fully distinguish between signals that are closely related, such as two different fingers. The signals that were identified were able to be translated into the physical output simulated on the Arduino circuit.

The sport of football has become one of the most widely loved and watched sports in the United States. Fans of football are extremely dedicated to the sport and form very personal, emotional attachments to teams within the National Football League. Through studying these fans, three main analysis topics will be addressed in this thesis: the established fan knowledge that creates rules within the fandom on how a fan participates and the exceptions to those rules, the need that fan's who do not fit into the normative patterns of the fandom feel to explain their motivations, and the degree of fanship that can be measured through a fan's explanation for their deviant behavior. For this fandom analysis, two sets of data will be referenced throughout the discussion. The first is anecdotal data pulled from various reddit threads on the personal experiences of each fan as well as some opinion sharing about the National Football League fandom. The second set of data is primary data that I have compiled via a survey. The established fan knowledge within this fandom is two fold: First, fans choose their team for a specific reason (usually based off of the team their parent's are a fan of or the state they grew up in), which typically takes place by age twelve. Secondly, once a fan chooses a team, they should stick with that team through their entire fanship. This second piece of fan knowledge is the most important rule within the fandom. This idea of loyalty is what guides fan participation. Identifying this rule led me to my main question about this fandom \u2014 if fans are so dedicated to their chosen team, what does it mean when someone switches to a new team. I feel that this breaking of a bond that seems so personal to fans is important and should be researched. This brought me to researching these fans that have switched teams, learning why, as well as what this group of fans can say about the National Football League fandom as a whole.

Traditions come about in a variety of ways varying from school to school and sport to sport. Fans in the NCAA have the most connection to their team’s traditions when they follow one or multiple dimensions of the P.A.T.H. framework. Traditions that are Passionate, Authentic, Tribal, and Historical help fans have a sacred, emotional bond between themselves and their favorite team. Most of the time, this bond makes people behave in a way that they do not normally. The best traditions create an atmosphere that allows someone to come back decades later and feel like they never left. When fans feel strongly toward the tradition, it creates a passion unlike any other. The fans will go through great lengths to keep the tradition happening. When a tradition comes about organically and is not forced on the fanbase, it follows the authentic dimension. Fanbases will not be willing to keep a tradition going if they feel like it was manufactured; it needs to be something that they want to do. The tribal dimension is created by the desire people have to be a part of a group because of a shared belief. People have a need to fit in and belong, so if a tradition is able to create this feeling, it will be more likely to stick. The historical dimension explains itself; a tradition that has been around for many years has a much better chance of being around for years to come because of the history associated with it. Traditions that encompass one or all of the dimensions of P.A.T.H. have a better chance of sticking and becoming a tradition that is recognized nationally. Traditions should eventually become something that completes the game day experience. At the end of the day, people will not remember exact plays that happened, but they will remember the experiences they shared with everyone else in the stands.

The America's Cup is the preeminent international sailing competition. Since the cup was first awarded to the United States in 1851 for winning a race around the Isle of Wight in England, it has been up for perpetual international competition. The purpose of this project is to assess the marketing strategies implemented for the 35th America's Cup which took place in Bermuda in June of 2017. Through qualitative and quantitative research I discovered the strengths and weaknesses of the current marketing strategies in addition to identifying opportunities for future Cups. While attending the 35th America's Cup in Bermuda I was able to conduct long interviews with several c-level executives of the America's Cup Event Authority as well as conduct a survey with attendees of the Cup. Analysis of this data allowed me to determine effective consumer awareness practices, ideal consumer involvement techniques, experience design, optimal marketing tactics, and strategic branding. I was also able to identify critical goals that the current Event Authority Management have set that embody their vision for future America's Cups. The ultimate objective of this research is to propose marketing strategies that will expand the influence of the America's Cup and transform it into an iconic and widely known sporting event in the United States. In previous years there has been very limited marketing invested in building awareness for the America's Cup so I plan to identify components that have brought them success in the past and then recommend new strategies and tactics that will successfully build awareness and increase viewership. These elements will then be able to be integrated into a marketing strategy and experience model for future America's Cups.

Description
Startle-evoked-movement (SEM), the involuntary release of a planned movement via a startling stimulus, has gained significant attention recently for its ability to probe motor planning as well as enhance movement of the upper extremity following stroke. We recently showed that hand movements are susceptible to SEM. Interestingly, only coordinated movements of the hand (grasp) but not individuated movements of the finger (finger abduction) were susceptible. It was suggested that this resulted from different neural mechanisms involved in each task; however it is possible this was the result of task familiarity. The objective of this study was to evaluate a more familiar individuated finger movement, typing, to determine if this task was susceptible to SEM. We hypothesized that typing movements will be susceptible to SEM in all fingers. These results indicate that individuated movements of the fingers are susceptible to SEM when the task involves a more familiar task, since the electromyogram (EMG) latency is faster in SCM+ trials compared to SCM- trials. However, the middle finger does not show a difference in terms of the keystroke voltage signal, suggesting the middle finger is less susceptible to SEM. Given that SEM is thought to be mediated by the brainstem, specifically the reticulospinal tract, this suggest that the brainstem may play a role in movements of the distal limb when those movements are very familiar, and the independence of each finger might also have a significant on the effect of SEM. Further research includes understanding SEM in fingers in the stroke population. The implications of this research can impact the way upper extremity rehabilitation is delivered.

Description
I worked on the human-machine interface to improve human physical capability. This work was done in the Human Oriented Robotics and Control Lab (HORC) towards the creation of an advanced, EMG-controlled exoskeleton. The project was new, and any work on the human- machine interface needs the physical interface itself. So I designed and fabricated a human-robot coupling device with a novel safety feature. The validation testing of this coupling proved very successful, and the device was granted a provisional patent as well as published to facilitate its spread to other human-machine interface applications, where it could be of major benefit. I then employed this coupling in experimentation towards understanding impedance, with the end goal being the creation of an EMG-based impedance exoskeleton control system. I modified a previously established robot-to-human perturbation method for use in my novel, three- dimensional (3D) impedance measurement experiment. Upon execution of this experiment, I was able to successfully characterize passive, static human arm stiffness in 3D, and in doing so validated the aforementioned method. This establishes an important foundation for promising future work on understanding impedance and the creation of the proposed control scheme, thereby furthering the field of human-robot interaction.
