Masters Theses
Hypoxia occurs when the body's tissues are unable to obtain adequate oxygen supply and is the primary environmental factor present when pilots are exposed to increasing altitude levels. Hypoxia leads to impaired vision, cognition, and motor control function, which can negatively affect performance and become deadly if a pilot becomes incapacitated. Thus, objective identification of early-onset hypoxia is critical to increase the time of useful consciousness and prevent physiological episodes. Of the few studies utilizing eye-tracking, there is disagreement and mixed results concerning saccadic eye metrics as a means to measure and detect hypoxia. Therefore, the purpose of this study …
Hardware Security Of The Controller Area Network (Can Bus), David Satagaj
Hardware Security Of The Controller Area Network (Can Bus), David Satagaj
Senior Honors Theses
The CAN bus is a multi-master network messaging protocol that is a standard across the vehicular industry to provide intra-vehicular communications. Electronics Control Units within vehicles use this network to exchange critical information to operate the car. With the advent of the internet nearly three decades ago, and an increasingly inter-connected world, it is vital that the security of the CAN bus be addressed and built up to withstand physical and non-physical intrusions with malicious intent. Specifically, this paper looks at the concept of node identifiers and how they allow the strengths of the CAN bus to shine while also …
Performance Optimizations Of Nosql Databases In Distributed Systems, Tristyn Maalouf
Performance Optimizations Of Nosql Databases In Distributed Systems, Tristyn Maalouf
Senior Honors Theses
Databases store information about a system and provide a mechanism for data to be accessed and manipulated. While advancements in the 1970s provided a relational database model that has persisted to this day, web-scale era mass data needs surfacing in the 1990s and the early 2000s revealed limitations in the scalability of the relational model. As systems grew and transitioned into distributed architectures to support mass data storage and parallel processing, a complete overhaul of distributed computing technologies evolved that fundamentally departed from the relational data model in favor of the NoSQL data model. The course of this research details …
Championing Christ In The Technical Workplace, Jonathan Habbick
Championing Christ In The Technical Workplace, Jonathan Habbick
Senior Honors Theses
Liberty University's goal of training champions for Christ is a high and lofty goal. Liberty has put in place classes and assignments throughout a student's time at Liberty that are aimed towards training them to be champions for Christ. However, many students who graduate from Liberty University are left lonely and unsure of how to go forth championing for Christ. This thesis will provide the motivation and encouragement for students to not only be champions for Christ but actually champion Christ, specifically in the technical workplace. In addition, this thesis evaluates Liberty's practices and will provide changes or additions that …
Net Energy Index: A New Way To Measure Energy Efficient Buildings, Dylan Suplee
Net Energy Index: A New Way To Measure Energy Efficient Buildings, Dylan Suplee
Senior Honors Theses
Energy efficiency indexes are useful for providing tangible measurements of energy efficiency in buildings. Buildings use approximately 70% of all electricity in the USA. Using that energy efficiently has two primary benefits: limiting greenhouse gas emissions and reducing grid strain. Utilizing local renewable energy sources contributes to the same benefits. Currently, there is no index that considers renewable energy sources when measuring energy efficiency. Therefore, this paper proposes the Net Energy Index, which compares the net power usage of a building to the floor area of the building in order to determine energy efficiency. If renewable energy supplies power to …
A Test Bed For Evaluating The Performance Of Iot Networks, Hope Harvey
A Test Bed For Evaluating The Performance Of Iot Networks, Hope Harvey
Senior Honors Theses
The use of smaller, personal IoT networks has increased over the past several years. These devices demand a lot of resources but only have limited access. To establish and sustain a flexible network connection, 6LoWPAN with RPL protocol is commonly used. While RPL provides a low-cost solution for connection, it lacks load balancing mechanisms. Improvements in OF load balancing can be implemented to strengthen network stability. This paper proposes a test bed configuration to show the toll of frequent parent switching on 6LoWPAN. Contiki’s RPL 6LoWPAN software runs on STM32 Nucleo microcontrollers with expansion boards for this test bed. The …
Investigating The Effects Of Flue Gas Injection, Hot Water Distribution, And Fill Distribution On Natural Draft Wet Cooling Tower Performance, John Stapleton
Investigating The Effects Of Flue Gas Injection, Hot Water Distribution, And Fill Distribution On Natural Draft Wet Cooling Tower Performance, John Stapleton
Senior Honors Theses
Natural draft wet cooling towers (NDWCT) are a common method of heat removal in powerplants. This study employs a numerical cooling tower model developed by Eldredge, Benton & Hodgson (1997) to examine whether utilizing nonuniform water, fill profiles, and flue gas injection can improve NDWCT efficiency. The results show that each of these variables can be optimized to lower outlet water temperature. Within the range tested for each parameter, the water profile had the most significant effect on outlet water temperature, followed by the flue gas temperature and then the fill profile. The optimum parameter combination reduced the predicted outlet …
Finding A Single Equation To Represent Urea Evaporation, Sublimation, And Decomposition In Selective Catalytic Reduction Systems, Noah Hertzler
Finding A Single Equation To Represent Urea Evaporation, Sublimation, And Decomposition In Selective Catalytic Reduction Systems, Noah Hertzler
Senior Honors Theses
Aqueous Urea used in Selective Catalytic Reduction (SCR) Systems undergoes three sequential processes that result in ammonia being produced to reduce harmful NOx emissions: Water evaporation, Urea sublimation, and Urea decomposition into ammonia and isocyanic acid. While these phases can be simplified by modeling the Urea as pure water, accuracy is sacrificed to do so. In order to make SCR modelling both accurate and simple, this project set out to find an equation that could represent all three processes. Simulations were run in ANSYS and Particle to generate a set of data, then an empirical equation was created to model …
