In Situ Water Sensing Systems: Research On Advancements In Environmental Monitoring, Abigail Seibel
In Situ Water Sensing Systems: Research On Advancements In Environmental Monitoring, Abigail Seibel
Honors Theses
In this work, two sensing systems were researched in order to improve in situ environmental monitoring. The first is a pH and Total Alkalinity sensor used to determine these characteristics of sea water. I explored the facets of this sensor over a 7-week internship with Dr. Ellen Briggs in her lab in summer of 2023. The second is a more holistic sensing system that reads temperature, turbidity, and pressure used for studying environmental characteristics of Alaskan bever ponds. Both systems were developed in close collaboration with scientists who are collecting data to better understand the impacts of climate change. Better …

Formula SAE is a multifaceted competition that involves student teams designing and competing with an open-wheel style race car. There are 5 different dynamic events included in the competition. Each event requires a unique aerodynamic setup to have the best performance possible. This design project focuses on a drag reduction system (DRS) that will improve aerodynamic performance, resulting in faster lap times and increased competitiveness. Key features include a direct electronic actuation mechanism that will allow the rear wing to be adjusted during a race. The benefits of the DRS system, include increased speed, improved handling, and greater fuel efficiency …
Creating An Automatic Lowering Function For Quarter-Scale Tractor Pulling Sled, Sam Wilkins
Creating An Automatic Lowering Function For Quarter-Scale Tractor Pulling Sled, Sam Wilkins
Honors Theses
As the agricultural industry works to continuously integrate innovative technology and improve production efficiency, improved on-board data acquisition and transmission will be necessary for all agricultural machines. To make this a reality, the utilization of controller area network (CAN) technology will be crucial. Therefore, it is important for all agricultural engineers to have foundational knowledge of CAN bus systems and the standards that govern their use in industry. The UNL quarter-scale tractor team regularly utilizes CAN buses on their tractors and testing equipment. One such testing machine is the team’s pulling sled, which uses CAN messages to transport important information …
Exploring The Use Of Virtual Reality In Designing And Prototyping Medical Devices, Evan Marsh
Exploring The Use Of Virtual Reality In Designing And Prototyping Medical Devices, Evan Marsh
Honors Theses
A degree in engineering is highly sought after in the United States. Despite the grueling coursework and sacrifices involved in earning an engineering degree, the rewards after college are numerous. However, the engineering field is vast, and the degree obtained is not always the profession followed in industry. A lot of what we learn in the college of engineering is very broad and surface-level. It is worth noting that only about 10% of what engineering students learn in school is applicable in the workplace, but they wish they had learned a lot more about that 10%.
Stump Grinder Project, Wyatt Hopper
Stump Grinder Project, Wyatt Hopper
Honors Theses
This project covers the analysis of a Portable Stump Grinder device sponsored by private investors known as Gary and Carol Sherman, two farmers out of Lincoln, Nebraska. The ultimate goal of this project, in terms of the work we were assigned, was to provide the foundation work for future engineering teams to design and build the stump grinder for Gary and Carol Sherman.
Modern Practices For Responsive Web Design And Web Accessibility, Keyaun Washington
Modern Practices For Responsive Web Design And Web Accessibility, Keyaun Washington
Honors Theses
Responsive web design and web accessibility play crucial roles in ensuring an optimal user experience on the web. By designing websites with responsiveness and accessibility in mind, more opportunities are opened up for a wider audience to access and interact with our content. Through modern practices, responsive web design allows websites to reach several different devices ranging from compact smartwatches to expansive television screens. Designing for accessibility provides accommodations for individuals with impairments while also providing benefits for individuals without impairments. However, designing for responsiveness and accessibility can present challenges; a poor attempt at providing accessibility features can worsen a …

Leadership And Project Management In Engineering: Baja Tube Bender, Maysyn Tm Sorensen
Leadership And Project Management In Engineering: Baja Tube Bender, Maysyn Tm Sorensen
Honors Theses
Typical coursework for Undergraduate Mechanical Engineering students does not deeply focus on project management and leadership. Detailed in the following documentation is review of my Mechanical Engineering Senior Design capstone project as well as analysis of final presentations of other capstone projects. The Senior Design capstone projects spanned both semesters of the ‘22-’23 academic school year. After the first semester of my project I produced a post-mortem report to analyze the project’s progress and suggest improvements for the project, design, and team interaction. These improvements were compiled into an action plan and implemented in the spring semester. When the project …

The scope of this report is an overview of the development of powered and unpowered aircraft, including lighter-than-air, heavier-than-air, and aerospace technologies. Aviation developments were generally not limited to one specific country or person, …
A Device For Measuring Acoustic Output Intensity Of Transcranial Doppler Ultrasound Transducers For Comparison With Fda Regulations, Sarah Altman, Gregory Bashford, Benjamin Hage
A Device For Measuring Acoustic Output Intensity Of Transcranial Doppler Ultrasound Transducers For Comparison With Fda Regulations, Sarah Altman, Gregory Bashford, Benjamin Hage
Honors Theses
Transcranial Doppler Ultrasonography (TCD) is a non-invasive methodology which can evaluate cerebral blood flow velocity in real time. Single-element focused circular transducers placed on the scalp produce ultrasound waves capable of penetrating the skull with minimal aberration, enabling measurement of the Doppler shift. As such, TCD can measure blood flow velocity in the internal carotid and vertebral arteries, as well as the arteries of the Circle of Willis: the Anterior Cerebral (ACA), Posterior Cerebral (PCA), and Middle Cerebral Arteries (MCA). Intracranial aneurysm and ischemic stroke are serious conditions in which ballooning or occlusion of cerebral vessels cause insufficient perfusion, leading …

Economic And Input-Use Efficiency Of Nitrogen Management Techniques In Non-Irrigated Maize Production, Katie J. Bathke
Economic And Input-Use Efficiency Of Nitrogen Management Techniques In Non-Irrigated Maize Production, Katie J. Bathke
Honors Theses
The efficiency of nitrogen (N) management has become a main concern in agricultural cropping systems for understanding the optimal N rate to help producers improve economically and reduce the exhaustion of natural resources environmentally. Nitrogen rates vary both temporally and spatially by the interactions of the soil environment and rainfall through a growing season. Thus, a site-specific approach can further optimize this variability with the understanding of the role soil variability plays in the N rate applied to a non-irrigated field. The objective of this study was to evaluate the various nitrogen treatments for their nutrient use efficiency and economic …
