Description
Usability in the Internet of Things (IOT) in the Smart Home is a new concept with limited current research, especially in user perception. User perception is an important aspect in the development of Smart Home Internet of Things systems, including smart home products and devices and in the design of the Smart Home experience. The aim of my thesis is to investigate user perceptions of Smart Home Internet of Things systems to understand how usable current Smart Home Internet of Things systems are from the perception of the user and how that impacts the Smart Home experience. By understanding the usability of Smart Home Internet of Things systems, we can better design Smart Home devices and products for a user-centered experience. My thesis informs the design of user-centered Smart Home Internet of Things systems and experiences.
This study includes a literature review and an empirical study. The empirical study is a usability testing survey that investigates user perceptions of Smart Home technology that make up the Internet of Things system in the Smart Home. Both closed-ended questions and open-ended questions are included in the survey for a comprehensive study. Main results showed that current smart home systems are somewhat usable. Results also showed that smart home users are satisfied with current smart home systems, believes that smart home technology adds value to their lifestyle, and will continue to use smart home technology. Main results showed that the strengths of current smart home systems design are efficiency, learnability, memorability, and enjoyability. Main results showed that there is a trend between age group and smart home user perceptions. These findings inform the design of user-centered smart home systems.

Description
The classification of financially at-risk is an expansive term that fits the personal profile of most individuals when it comes to the conditioning of their attitude toward money management, particularly in the planning and investment of that money for the achievement of long-term goals. In the case of this thesis, we focus primarily on those who have made a career in professional athletics and entertainment. The behavioral finance tendencies of these two industry professions are widely regarded as insufficient and often damaging the to the longevity of achieved financial security. This ideology stems primarily from an environment where individuals enjoy rapid wealth accumulation in a highly competitive and constantly transitioning role within their respective crafts. The subjectively common behavioral shortcomings of these world-class athletes and performers and uncertain day-to-day security of the professions which these at-risk individuals possess make for highly unfavorable circumstances when striving to achieve a lifetime of income and a secure retirement. In examining individuals of these classes who have faced grave financial hardship, this thesis will serve as a basis for identifying measures to recondition problematic behavioral tendencies that ultimately cause disengagement from a prudent financial plan. Therefore, this thesis will also serve as a framework to determine what investment strategies will complement the behavioral modifications financial planners strive to instill in these individuals, so that professional athletes, celebrities, and financially at-risk professionals alike may achieve higher probability of creating financial freedom through the engaged execution of a goals-based financial plan.

Problem Statement
Company X does not currently have a proven hedging method that allows for forecasting flexibility and currency fluctuations, while still reducing the risk of de-designation in their international construction projects. To solve this issue, we will analyze historical currency fluctuations over the past 5 years, forecasting error rates, the impact of de-designation, and earnings per share impact.

Description
This study aimed to quantify glare induced into the NICU through phototherapy devices commonly used to treat neonatal jaundice. The blue light associated with the devices can cause a number of physiological affects including melatonin suppression, disturbances of one's circadian rhythm, and has the potential to lead to risk factors of age-related macular degeneration (AMD) in the long term. The study found that the phototherapy device tested emitted a sufficient amount of light to be considered 'disturbing' using the DeBoer scale. Due to this, phototherapy devices in the future should take into consideration the minimization of light emitted which is not directly treating the infant on the device to prevent potential physiological effects that nurses may experience.

Description
The effect of three different drug modulators on the electrophysiological response of Aplysia neurons was observed through the use of extracellular and intracellular recordings. Extracellular recordings captured the effects of magnesium chloride and glutamate at a variety of concentrations for each. Intracellular recordings displayed the effects of magnesium chloride, glutamate, and GABA for two concentrations each. For extracellular recordings, the average firing rate, average peak-to-peak voltage, average SNR, and sorted units were considered. For intracellular recordings, average firing rate, average peak voltage, and average resting potential were considered. Significance of data could not be determined using statistical analysis due to having a sample size of 1 for every experiment.

Description
For my honors thesis, I developed a proof of concept alpha prototype of a biomedical device for detection of cerebrospinal fluid leaks during spinal surgery. Cerebrospinal fluid leaks are a consequence of tears in the dura mater of the spinal cord and can result in potentially life-threatening conditions and are overall a large burden not only on the patient but upon the clinical teams managing the patient postoperatively. What I created was an optical sensor that I programmed to be sensitive to detecting green wavelength light. The device would ideally be attached to surgical drain tubing and used in conjunction with fluorescein (a green fluorescent dye) infused lumbar punctures into the spinal canal of patients. As the dye circulates through the spinal cord, any tears in the dura mater would cause the fluorescein to leak out with cerebrospinal fluid into the incision site. This fluid may then be collected by the surgical drain where the sensor may detect the fluorescein, triggering a buzzer response that would notify the patient or the surgeons of an ongoing leak that requires repair. The time I spent on my thesis involved sensor validation to ensure it could differentiate between colors, testing the sensor's color sensitivity by performing a fluorescein aliquot, and running proof of concept testing that could show the sensor can detect fluorescein drain tubing and provide an adequate response. The sensor was able to differentiate between varying concentrations of fluorescein in solution and provided exceptional results in its proof-of-concept testing. Next steps will be to re-run the sensor validation study with different dyes as well as consolidating the device's electrical hardware onto a single circuit board as development of beta and gamma prototypes move forward.

Description
This thesis examines two electronic games, PlayerUnknown’s Battlegrounds (PUBG) and Fortnite, which rose to popularity as battle royale-style videogames, to question whether they are viable candidates for success as esports. In his 2018 Barrett Honors Thesis, Noah Hilliker developed a model for assessing electronic games as successful esports. His thesis, titled “Ambassador Communities, Hybrid Spectatorship, and Other Indicators of Success in eSports” applied his model of indicators of success to League of Legends, Overwatch and Hearthstone. In this thesis, I have applied his indicators to (PUBG) and Fortnite, which differ significantly from the games he previously analyzed, precisely as I argue here, because they are battle royale games. These indicators fall under three categories: the nature of fans, the overall design of the game and the relationship between game developers and fans. The data that was examined for this investigation included academic literature on esports, posts on online platforms, news articles, YouTube content and forums. The following indicators were analyzed in their application to the collected data for both games: self-organization, spectator-player hybridity, ambassadors, clear center of action, demonstration of skill, mechanical variance, game balance, character of fan/developer relationship and feedback to fans. Through this project, I apply a previous approach to analyzing esports success to two games, Fortnite and PUBG, in order to analyze how well the model fits battle royale-style games.

Description
Photovoltaic panels are commonly used for their versatility in on-site generation of clean electricity in urban environments, specifically on rooftops. However, their implementation on rooftops poses potential (positive and negative) impacts on the energy use of buildings, and urban climates. The negative impacts are compounded if PV is installed on top of a high-albedo rooftop. This study quantitively investigates these impacts from PV installation on top of a building with a white roof in Phoenix, AZ. We supplemented our measurements with EnergyPlus simulations to model the energy implications for archetypical residential and retail buildings and calculated the energy penalty to generation ratio as well as sensible heat flux for each combination of panel height and building type. Results indicate that the daily cooling energy penalty to due blockage of outgoing longwave radiation can be 4.9—11.2% of the PV generation. In addition, while we observed a small decrease in nighttime sensible heat flux to the ambient, PV cases increased the daytime heat flux by more than a factor of 10. This study highlights the potential unintended consequences of rooftop PV under certain conditions and provides a broader perspective for building designers and urban planners.

Characterization of particulate process and product design is a difficult field because of the unique bulk properties and behaviors of particles that differ from gasses and liquids. The purpose of this research is to develop an equation to relate the angle of repose and flowability, the ability of the particle to flow as it pertains to particulate processes and product design. This research is important in multiple industries such as pharmaceuticals and food processes.

Description
International refugees have continuously shaped the identity of modern London, England, creating a diverse cityscape. However, the referendum in June 2016 indicated a perceived desire of the majority of United Kingdom (UK) citizens to leave the European Union (EU) and the domination of far-right, anti-immigrant rhetoric in British politics. These elements have given rise to the question of how refugees will find belonging in a geographical space that continues to create borders at both a national and borough level. As the Brexit vote still stands, barriers to applying for refugee status and successful resettlement could increase - complicating the lives of refugees wanting to resettle in the UK. Urban spaces such as London, Manchester, and Birmingham have transformed into places where the lives of the British cross daily with the lives of those forcibly removed from their home state. With minimal current research on the relationship between international refugees in London and the current social and political identity of the city, post-Brexit vote, I believe there is a gap in understanding to be filled. This gap includes defining the relationship between place, people, and politics in the context of the city of London as well as the boroughs that comprise the city. In addition, this research explores the future of London as a place at a borough-level and aims to understand how the idea of borders and nationalism have been uncovered and subsequently amplified through the referendum. The following paper includes data collected from British refugee agencies and inhabitants of five London boroughs that will add to existing research in the form of academic and professional journals and published reports produced by refugee agencies and the British government in hopes to identify the current nature of the relationship between international refugees and Londoners and how this relationship might shift in the future.
