Within recent years, the drive for increased sustainability within large corporations has drastically increased. One critical measure within sustainability is the diversion rate, or the amount of waste diverted from landfills to recycling, repurposing, or reselling. There are a variety of different ways in which a company can improve their diversion rate, such as repurposing paper. A conventional method would be to simply have a recycling bin for collecting all paper, but the concern for large companies then becomes a security issue as confidential papers may not be safe in a traditional recycling bin. Salt River Project (SRP) has tackled this issue by hiring a third-party vendor (TPV) and having all paper placed into designated, secure shredding bins whose content is shredded upon collection and ultimately recycled into new material. However, while this effort is improving their diversion, the question has arisen of how to make the program viable in the long term based on the costs required to sustain it. To tackle this issue, this thesis will focus on creating a methodology and sampling plan to determine the appropriate level of a third-party recycling service required and to guide efficient bin-sizing solutions. This will in turn allow for SRP to understand how much paper waste is being produced and how accurately they are being charged for TPV services.

Technological applications are continually being developed in the healthcare industry as technology becomes increasingly more available. In recent years, companies have started creating mobile applications to address various conditions and diseases. This falls under mHealth or the “use of mobile phones and other wireless technology in medical care” (Rouse, 2018). The goal of this study was to identify if data gathered through the use of mHealth methods can be used to build predictive models. The first part of this thesis contains a literature review presenting relevant definitions and several potential studies that involved the use of technology in healthcare applications. The second part of this thesis focuses on data from one study, where regression analysis is used to develop predictive models.

The primary purpose of this paper is to evaluate the energy impacts of faults in building heating, ventilation, and air conditioning systems and determine which systems’ faults have the highest effect on the energy consumption. With the knowledge obtained through the results described in this paper, building engineers and technicians will be more able to implement a data-driven solution to building fault detection and diagnostics

In the United States alone, commercial buildings consume 18% of the country’s energy. Due to this high percentage of energy consumption, many efforts are being made to make buildings more energy efficient. Heating, ventilation, and air conditioning (HVAC) systems are made to provide acceptable air quality and thermal comfort to building occupants. In large buildings, a demand-controlled HVAC system is used to save energy by dynamically adjusting the ventilation of the building. These systems rely on a multitude of sensors, actuators, dampers, and valves in order to keep the building ventilation efficient. Using a fault analysis framework developed by the University of Alabama and the National Renewable Energy Laboratory, building fault modes were simulated in the EnergyPlus whole building energy simulation program. The model and framework are based on the Department of Energy’s Commercial Prototype Building – Medium Office variant. A total of 3,002 simulations were performed in the Atlanta climate zone, with 129 fault cases and 41 fault types. These simulations serve two purposes: to validate the previously developed fault simulation framework, and to analyze how each fault mode affects the building over the simulation period.

The results demonstrate the effects of faults on HVAC systems, and validate the scalability of the framework. The most critical fault cases for the Medium Office building are those that affect the water systems of the building, as they cause the most harm to overall energy costs and occupant comfort.

During my fourth year at Arizona State University, I enrolled in two capstone projects while working towards my
undergraduate degree in aerospace engineering. The first of the two team projects was an aerospace capstone: Design of
Autonomous Aircraft Systems. The second being a capstone project based out of Arizona State’s design school:
Innovation Space. The purpose of this dual enrollment was to compare and contrast the two product development projects,
in hopes to recommend a course of action to engineers younger than myself who are presented the option of multiple
capstones. This report will elaborate on three areas of engineering design and how they were realized in these projects.
These 3 topics are product development and its effect on design to manufacture, design feature creep, and technical vs
non-technical design. After considering the pros and cons of both capstone projects and their relation to the three main
topics of this report, it was decided that individuals who are motivated to become the best engineers they can be upon
graduating from an undergraduate program, they should find the time to take both capstone courses. Both Design of
Autonomous Aircraft Systems and Innovation Space present opportunities to create new ways of engineering thinking, all
of which will be necessary for an engineer to succeed in his/her first years in industry.

Research indicates that over 7.7% of adults who seek medical care every year at a hospital report a delay in receiving care, having difficulty receiving care, or being unable to receive care due to long waiting times (Kennedy et al. 2004). This continue to stir the need for researchers to explore ways to extend healthcare services in minimal waiting times. This thesis research utilizes Arena, a discrete event simulation software, to analyze waiting times in a typical hospital setting. It goes on to explore the impact of cross training of hospital personnel in meeting the critical needs of patients while minimizing waiting times. Simulation output data were analyzed, and cross training was found to have significant impact on reducing waiting time when: intake of patients is higher than current (original) arrival rate, intake of appointment patients is highest, or intake of emergency patience is highest of the three patient categories.

This project evaluates the success that a Food Waste assignment had on reducing food waste by exploring factors that suggest waste minimization. Previous ASB 370/394: Ethics of Eating students were surveyed regarding their thoughts on their current food waste behavior and what food waste strategies they implemented to reduce their waste. The success of the assignment was determined using SPSS statistical software. Respondents reported that foods that they waste the most were vegetables, fruits, and bread and most respondents indicated that they threw away 1-2 cups of food per week, typically only when they clean out their fridge and/or pantry. Participants revealed the main reasons for their food waste were “I buy too much,” followed by “do not have time to prepare the food I buy,” and “my produce didn’t look appealing anymore.” Based on the results from the survey, over 60% of respondents indicated that they had changed their food waste behavior to produce less waste. The Food Waste Assignment was deemed a success in encouraging students to limit their food waste due to the majority of students indicating they change their behavior after completing the assignment. The three main tactics students implemented to reduce their food waste were: “eating more leftovers,” “proper food storage,” and, “meal planning.” While the Food Waste Assignment was successful, ways to improve the assignment were still identified. To help students address their food waste behavior, reading or videos on ways to prevent food waste or suggestions for students to improve their food waste could be provided.

Motorcycle fatalities have been increasing at a faster rate than the number of motorcycles being registered in the United States. There is limited analysis on the causes of fatal motorcycle crashes, specifically regarding different demographics, certain driver behavior, and various crash characteristics. It is important to be aware of how these factors relate to each other during a fatal motorcycle crash. This analysis focuses on these factors and explores potential steps to decrease motorcycle fatality rates using research and data from the Fatality Analysis Reporting System (FARS) from the National Highway Traffic Safety Administration (NHTSA), and data from the National Household Travel Survey (NHTS). Based on this data, there are noticeable trends between different genders and age groups. According to the analysis, males have a higher fatality rate than females, and their fatal crashes tend to involve multiple driver infractions such as drinking, speeding, not wearing a helmet, and driving without a license. Similarly, younger drivers have a higher fatality rate than older drivers, and their fatal crashes tend to involve multiple driver infractions. Although older drivers involved in fatal crashes usually drive more cautiously, they tend to be involved in single-vehicle crashes more often than younger drivers. Moving forward, implementing certain training programs directed towards particular demographics has the potential to decrease motorcycle rider fatalities.
