Description
In the past, Industrial Engineering/Engineering Management Capstone groups have not provided adequate documentation of their project data, results, and conclusions to both the course instructor and their project sponsors. The goal of this project is to mitigate these issues by instituting a knowledge management system with one of ASU’s cloud storage tools, OSF, and by updating course rubrics to reflect knowledge sharing best practices. This project used existing research to employ tactics that promote the long-term use of this system. In addition, data specialists from ASU Library’s Research and Data Management department were involved.

Description
End the Silence, End the Violence is a creative project to aid victims of domestic violence. There is a website, pamphlet, video and presentation attached that explains statistics, encourages awareness, and provides victims with access to shelters and legal resources. The website and the pamphlet are intended to put all resources in one place, making them easily accessible for victims of domestic violence. The legal terms were explained, helping any victims who may not have a legal background understand how the court process works. On the website, the adult court process is explained in simple language. Orders of protection are also explained, as well as how to access them, with the direct links to the forms provided. Domestic Violence Shelters in Maricopa county are also listed, along with contact information. All of these shelters were contacted, and were verified to be open for a minimum of one year from October, 2019, and are still accepting victims. No addresses were provided on either the website or the pamphlet, with the hopes that not providing locations will better protect the victims who are seeking help. The pamphlet includes these same shelter resources, along with contact information. The presentation includes domestic violence statistics, as well as important terms and definitions. Finally, there was a video to encourage awareness towards domestic violence. Purple and red paint was used to demonstrate common places these victims suffered abuse, with the purple representing sexual violence, and the red representing physical violence. Not all of the volunteers in the video are victims of domestic violence, but are all advocates for ending domestic violence and helping with prevention.

Description
Mass nuclear catastrophe is a serious concern for society at large when considering the rising threat of terrorism and the risks associated with harnessing nuclear energy. In the case of a mass nuclear/radiological event that requires hundreds of thousands of individuals to be assessed for radiation exposure, a rapid biodosimetry triage tool is crucial [1]. The Cytokinesis Block Micronucleus Assay (CBMN) is a promising cytogenetic biodosimetry assay for triage [2]; however, it requires shipping samples to a central laboratory (1-3 days) followed by a lengthy cell culture process (~3 days) before the first dose estimate can be available. The total ~ 1 week response time is too long for effective medical care intervention. A shipping incubator could cut the response time in half (~3 days) by culturing samples in transit; however, possible shipping delays beyond 2 days without the addition of a necessary reagent (Cyto-B) would ruin the integrity of the samples—for accurate CBMN assay endpoint observation, Cyto-B must be added within a 24-44 hour window after sample culture is initiated. Here, we propose a “Smart” Shipping Incubator (SSI) that can add Cyto-B while samples are in transit through a centrifugal system equipped with microfluidic capillary valve caps. The custom centrifugal system was constructed with CNC machined and 3D printed plastic parts, controlled by a custom printed circuit board (PBC) microcontroller, and housed inside a commercial shipping incubator (iQ5 from MicroQ Technologies). Teflon-coated, pre-pulled glass micropipettes (FivePhoton BioChemicals) were used as microfluidic capillary valve caps. Release of Cyto-B was characterized by a desktop centrifugal system at different tip sizes and relative centrifugal forces (RCFs). A theoretical model of Cyto-B release was also deduced to aid the optimization of the process. The CBMN assay was conducted both in the SSI with centrifugal Cyto-B release and in a standard CO2 incubator with manual addition of Cyto-B as the control. The expected mechanical shock during shipment was measured to be less than 25g. Optimal Cyto-B release was found to be at 35g RCF with a Teflon-coated 40 µm tip. Similar CBMN dose curves of micronuclei per binucleated cells (MN/BN) vs. exposed radiation (Gy) were produced for samples assessed conventionally and with the SSI. The similarities between the two methods suggest that centrifugation does not significantly affect the CBMN assay.

Description
Consumption of clean, pathogen-free water is vital in maintaining health. The water infrastructure in Puerto Penasco, Sonora is not sufficient in providing clean water for its residents. Water in this region is being overdrafted, meaning it is distributed from deep wells faster than it can be regenerated, which prevents more wells from being constructed. There is a high need for a cost-efficient solution to the clean water shortage in this impoverished town. The purpose of this study was to determine: (1) how clean drinking water affects health, (2) how contaminated water and water substitutes, such as soda and juices, negatively impact health, and (3) the impact on water consumption by local residents after providing them with a portable filtration system to create clean drinking water in their own homes. Water filters were distributed in two trials to a convenience sample of 45 participants, 27 of whom were successfully contacted for a post-implementation survey. Out of the 27 participants who took the survey, 27% reported that they drank more water after receiving the filter than before, 40% reported drinking less soda after receiving the filter, 63% reported using their filter on a daily basis, 63% believed that drinking clean water is important for their health, and 74% thought that it was difficult for them to obtain clean drinking water before receiving the filter. Providing residents with a filtration system was effective in increasing water consumption and saving residents money on water but did not provide conclusive data, negating the use of soda as a water substitute. This was an effective small-scale solution to a much larger problem that may be beneficial in other similarly impoverished communities.

Description
Prison dog training programs, which emerged in the 1980s, have been gaining popularity at both a national and international level. The programs allow inmates to train dogs as service animals for veterans and first responders. After reading several different research projects that examined the impact of dog training programs in prison, the majority of them show that there are a lot of benefits and a few challenges. The beneficial impact was examined both with an in-person walkthrough of a prison with the program and through a series of interviews conducted for the purposes of this study. Interviews were conducted with Sister Pauline Quinn, the founder of prison dog training programs; Patricia Barnhart, who previously managed a dog training program at a Florida prison; the director at New Life K9s, Nicole Hern, and all the inmates in the New Life K9s prison program at the Men’s Colony prison in California. Bringing dogs into prisons has created a change in inmate behavior, staff behavior, and a safer, calmer environment for those within the prison. Calming the prison environment allows inmates to develop skills they can take with them when they leave prison, which in turn will help reduce recidivism. The research suggests that starting a dog training program in the state of Arizona could significantly benefit the state prison system, community and everyone involved.

Description
This paper presents a variable damping controller that can be implemented into wearable and exoskeleton robots. The variable damping controller functions by providing different levels of robotic damping from negative to positive to the coupled human-robot system. The wearable ankle robot was used to test this control strategy in the different directions of motion. The range of damping applied was selected based on the known inherent damping of the human ankle, ensuring that the coupled system became positively damped, and therefore stable. Human experiments were performed to understand and quantify the effects of the variable damping controller on the human user. Within the study, the human subjects performed a target reaching exercise while the ankle robot provided the system with constant positive, constant negative, or variable damping. These three damping conditions could then be compared to analyze the performance of the system. The following performance measures were selected: maximum speed to quantify agility, maximum overshoot to quantify stability, and muscle activation to quantify effort required by the human user. Maximum speed was found to be statistically the same in the variable damping controller and the negative damping condition and to be increased from positive damping controller to variable damping condition by 57.9%, demonstrating the agility of the system. Maximum overshoot was found to significantly decrease overshoot from the negative damping condition to the variable damping controller by 39.6%, demonstrating an improvement in system stability with the variable damping controller. Muscle activation results showed that the variable damping controller required less effort than the positive damping condition, evidenced by the decreased muscle activation of 23.8%. Overall, the study demonstrated that a variable damping controller can balance the trade-off between agility and stability in human-robot interactions and therefore has many practical implications.

Description
Opening a business is often an exciting time in one’s life, as they take their business idea into the marketplace. But, most individuals fail to adequately address whether their business can actually succeed before entering the marketplace. The thesis, Creating a Successful Gluten-Free Bakery: A Financial Model and Analysis analyzes whether or not a gluten-free bakery is a viable business to open in today’s marketplace. By costing the main financial variables, creating a financial model of a gluten-free bakery, and running scenario analysis, I was able to find whether or not opening a gluten-free bakery was a viable business in today’s marketplace.

Description
An existing house is outdated and in need of a renovation. The kitchen, living room, bar and dining room are currently all closed off from one another creating four separate spaces. The goal is to recreate the main floor into an open concept space, that is great for entertaining, and being with family and friends. This Thesis/Creative Project deals in the area of structural redesign, aesthetics, client relations and budget tracking. To do this effectively, Revit, AutoCAD, RISA 3D and Excel will all be used to complete various elements of the project. In order to open the space a structural analysis needs to be done to ensure the structural integrity of the home remains solid. If structural walls are being removed the forces being exerted on those walls will need to be redistributed. This will require a redesign of the structural members to ensure the forces are supported. Once the walls are down the area can be redesigned to ensure function and usability. Every inch of the space needs to be optimized to ensure the most efficient use of space. The storage will also need to be taken into consideration because there will be storage loss when removing walls. The space will need to look aesthetically pleasing and keep in theme with the country cabin feel of the home. The Client’s will be involved in every step of the process to ensure they are satisfied with the varying design. While redesigning the area there is a strict budget that was set by the Clients, and every step of the designing process needs to take into consideration the cost. Once the successful completion of the project is accomplished, the Clients, will have the ability to take the plans and complete the renovation on the house.

Description
Following the prolific car-centric design of the twentieth century, many cities are grappling with increasing pedestrian deaths and greater vehicle congestion. To solve these problems, many of these cities are expressing a desire to create more effective and vibrant walkable places. Aside from safety, numerous benefits come from pedestrian friendly communities, including greater economic activity, better health, greater social capital, and less environmental impact. Although there are several tools already available, evaluating an area’s current walkability situation is still varied, and evaluating a pedestrian’s thoughts on safety and enjoyability is also difficult. The benefits of walkability and past and present tools are summarized in this paper. The goal of this paper was to create a walkability evaluation tool that included smaller, often overlooked aspects of the sidewalk and site design that contribute to a pedestrian’s experience and safety. The author developed a tool containing 40 different measures of the sidewalk concerning safety, connectivity, enjoyment, and accessibility, as well as created methods for visualizing the data. The tool was then utilized to gather data at six Phoenix-metro area intersections using a combination of on street data collection and GIS software and Google Street View. The paper also details suggestions on how to act upon the data and improve walkability in an area, including minor street alterations and larger policy shifts in zoning codes. Although in preliminary data collection the tool provides a good snapshot of the data, further development of the tool and assessment of its reliability are needed, as well as greater data collection to compare evaluated areas to a larger region.

Description
A heterogeneous team of robots working in symbiosis can maximize their strengths while complementing each other’s weaknesses. These simple robots can achieve more working together than they could on their own but cost less than a single robot with the same combination of capabilities. This project aims to validate the symbiotic relationship of an Unmanned Aerial Vehicle (UAV) and an Unmanned Ground Vehicle (UGV) with a physical implementation of a heterogenous team of robots and a demonstration of their capabilities. This paper details the selection of robots, the design of the physical coupling mechanism, and the design of the autonomous controls. An experiment was performed to assess the capabilities of the robots according to four performance criteria. The UGV must navigate a space while the UAV follows. The UAV must couple with the UGV. The UAV must lift the UGV over an obstacle. The UGV must navigate the space while carrying the UAV.
