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 …

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 …

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 …

Multiple Case Study Of Science And Engineering Integration In Secondary School Across Six School Districts, Elizabeth Hasseler, Elizabeth B. Lewis
Department of Teaching, Learning, and Teacher Education: Faculty Publications
A multiple case study was conducted to investigate six districts’ approaches to integrating science and engineering curricula in their secondary education programs. Data collected included classroom observations, interviews with teachers and administrators, college transcripts, professional development, and curriculum, as well as how, and how district personnel supported, and teachers enacted classroom instruction to align with the Next Generation Science Standards (NGSS). Six districts were chosen due to their ranges in their size, urban or rural context, and demographics. There were 25 participants in the study who were either district personnel or secondary teachers. All school districts in the study incorporated …

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 …

Effective irrigation and agricultural water management (IAWM) is critical for food security and water security. A key requirement in designing, implementing and operation of IWM is the necessary knowledge and capacity on the farm, in the service industry and within the supply chain. Educational opportunities that not only teach the relevant principles of irrigated agriculture, but also the necessary applied skills are essential. An Irrigation Field Course was initiated by the IHE Delft Institute for Water Education (IHE Delft) and was later developed as a joint field course with IHE Delft, the University of Nebraska-Lincoln (UNL), and the Daugherty Water …
