The Impact Of Relative Bridge Width On Highway Crashes In Nebraska, Mujahid Ali Bahadur

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

This research examines how bridge width relative to the approach roadway affects crash occurrence on Nebraska highways. The Nebraska Department of Transportation-(NDOT) Bridge Design Manual sets minimum bridge widths based on roadway classification, traffic projections, and the American Association of State Highway and Transportation Officials’ (AASHTO) Load and Resistance Factor Design (LRFD) criteria. While these guidelines ensure structural and functional adequacy, they do not incorporate safety performance analyses based on crash data. This leaves an important gap in understanding how bridge and approach roadway width decisions influence safety outcomes.

This research has four objectives: (1) evaluate crash frequency across different …

Characterization Of Sediment Loads And Size Distribution In Nebraska Roadway Runoff, Pavel Shrestha

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

The Nebraska Department of Transportation (NDOT) must manage sediment and pollutant loads from roadway runoff to meet stormwater regulations for discharges into impaired waters. The SAFL Baffle, a hydrodynamic separator used by NDOT, depends on accurate estimates of total suspended solids (TSS) and particle size distribution (PSD). However, existing studies show large variability in these characteristics, limiting their relevance to Nebraska roadways.

This study monitored stormwater runoff for 1.5 years at four NDOT-maintained sites—two in Lincoln and two in Beatrice—that received runoff from areas outside the roadway right-of-way. The SAFL Baffle was evaluated using the SHSAM (Sizing Hydrodynamic Separators and …

The Big Bang Theory’S Blurred (Tele)Vision Of Scientific Ethics: Some Thoughts For Educators Who Want To Change The Channel, Lee-Anne Broadhead, Sean J. Howard

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This article investigates the way the popular American television program The Big Bang Theory represents the pursuit of scientific knowledge and reflects on the cultural and educational implications of the show’s contradictory problematization and valorization of the reductionist method at the core of modern Eurocentric science. Drawing on story-lines relating to military research, animal experimentation, and pharmaceutical drug trials, we consider the show’s precarious balance of implicit critique (the consistent exposé of systematically violent, often unethical research) and overt celebration (the presentation of science as “cool,” and its practitioners as flawed but endearing). This tension, we argue, enhances the show’s …

Interview With Orca Award Winner Donald Weeks; Unl Biochemistry; Biotechnology, Mark Griep, Donald Weeks

UNL ORCA Interview Series

Emeritus Professor Donald Paul Weeks was awarded the ORCA in 2014, a year before he retired. He grew up in a small farm south of Terre Haute, Indiana.

“The Good Life” Of Ai, Lauren Smith

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Artificial Intelligence, or AI, is powered by data centers, sprawling warehouses of servers that require massive amounts of electricity and water to operate. The United Statesalready has more than 1,000 data centers, with nearly 400 more on the way.

Nebraska is next. Google is building a major new data center in North Lincoln, adding to the 18 operating across the state.

Our collective use of tools like ChatGPT, Google’s Gemini and Microsoft’s Copilot has fueled a boom in generative AI, and with it a surge in energy and water consumption.

The need for AI regulation isn’t a future concern. It’s …

The Myth Of Clean Manufacturing, Andrea Phan

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

We must act now and reform renewable energy credits to reflect real progress. This means tightening Scope 2 rules so that renewable claims are tied to additional, time and location matched, clean power. It means rewarding measurable integration, so that real emissions are avoided, not waived by retroactive certificates. RECs can still play a role, but only in a system that demands we use the tools we already have.

Learn To Fly: Enabling Deep Learning Based Perception And Control In Aerial Robotics, Krishna Muvva

School of Computing: Dissertations, Theses, and Student Research

Uncrewed Aerial Vehicles (UAVs) are increasingly deployed in dynamic, GPS degraded, and cluttered environments, yet their autonomy remains fundamentally constrained by limitations in onboard perception and real-time control. This dissertation addresses these challenges by proposing a unified framework that co-designs deep learning-based perception and model-based control, organized around three core thrusts: Learn to Track, Learn to Localize, and Learn to Evade.

Learn to Track develops dynamic and adaptive perception control mechanisms that optimize CNN inference for target tracking. A control-aware CNN framework dynamically adjusts inference frequency based on UAV motion, reducing latency while maintaining visual lock. An adaptive CNN with …

Exudation Entomology, John Buchanan

Department of Entomology: Distance Master of Science Projects

My master's project is exudation entomology. I propose a new area of entomology that will renew and reshape the science, answer questions that have been explored, and open new questions that have yet to be asked.

Exudation entomology is the study of exudates from arthropods. This includes (but is not limited to) honey, saliva, silk, secretions, venom, pheromones, paper, wax, and more. Other properties, such as bioluminescence, sounds, and odors, are also included. Exudation entomology will explore the chemical makeup of exudates, the anatomical mechanisms for how the arthropod produces the exudate, why the exudate is essential for arthropods and …

Nanjundaswamy

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

The modified Course-Based Undergraduate Research Experience (CURE) in bioenergy research evaluated four upland switchgrass cultivars namely Carthage, NE2010, RC Sundance, and Sunburst for bioethanol production using a separate hydrolysis and fermentation (SHF) process. The cultivars were not different in their biomass composition, sugar and ethanol yields. Carthage produced the highest ethanol yield (10 g/L), followed by Sunburst (9 g/L). A strong correlation was observed between glucose concentration at 48 hours (maximum glucose release) and ethanol yield at 72 hours. Ethanol production increased after 48 hours, and by 72 hours, residual glucose levels in the fermentation medium were negligible. The fermentation …

Native Americans, Part Ii, Kevin Abourezk

Truth and Reconciliation History Project

The Civil Rights Movement of the 1950s and 1960s – aimed at abolishing legalized racial segregation and discrimination across the United States – found expression in Nebraska in many ways. From college protests to marches in Lincoln, the movement found a home within the youth and counterculture communities of Lincoln and Omaha. But less known is the way the movement impacted Native American populations, especially those in remote Nebraska communities. “Just as young Hispanics, Asians, and Native Americans across the nation were learning the lessons of the black experience of the 1960s and expressing their identity as they sought to …

Exclusion From The Good Life: The Impact Of Anti-Asian Racism On Asian Nebraskans, Heather Fryer, Sharon Ishii-Jordan

Truth and Reconciliation History Project

To understand how Americans of Asian descent experienced, adjusted, and overcame negative experiences in Nebraska, recognizing the external forces on their lives is paramount. The experiences of Asians in their diaspora across the U.S. and Nebraska during a 150-year span have been shaped by both external (global and domestic) and internal (personality and resilience) factors. The presence of stereotypes specifically targeted toward Asian Americans due to exotic imaginings, pseudoscience, and economic fears, in addition to the images created by national media, gave rise to society’s acceptance of stereotypes. These external factors contributed to a belief that continues to this day …

Repair/Preservation Of Concrete Compression Members In Bridges Using Ultra-High-Performance Concrete (Uhpc), Mohammed Hedia, George Morcous

Nebraska Department of Transportation: Research Reports

As of 2024, approximately 36% of bridges across the United States require repair or replacement, with 7% classified as structurally deficient. The estimated cost to address these deficiencies exceeds $260 billion. In recent years, Ultra-High-Performance Concrete (UHPC) has emerged as a repair material for infrastructure preservation, drawing increased attention from transportation agencies and researchers worldwide.

Drift Dynamics Of Early Life-Stage Invasive Carps, Saurav Karki

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Asian carp species pose significant ecological threats to North American freshwater systems due to their invasive nature and prolific reproduction. Their semi buoyant eggs develop while drifting downstream with the river current. Understanding early life-stage transport is therefore critical for predicting recruitment potential and guiding management efforts. Existing fluvial egg drift models, including those relying on 1-D hydraulics and fully 3-D CFD-based models, are either inadequate for complex braided rivers or too computationally demanding for large-scale application. The Platte River in Nebraska, characterized by wide, shallow, multi-threaded channels, is dominated by two-dimensional flow conditions, making a depth-averaged 2-D modeling approach …

Impact Of Humidity From Shrink (Wrap) Tunnels On Refrigeration Systems: Comparing Economic And Environmental Impact Of Natural Gas And Electric, Segun Samuel Oladipo

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

This thesis examines the economic and environmental effects of electric and steam shrink-wrapping tunnels used in beef packaging processes, paying particular attention to the indirect refrigeration loads caused by the heat and humidity that each system releases. Traditional sustainability evaluations frequently ignore these indirect impacts, which are especially important in meat processing facilities where 45–55% of electricity use is attributed to refrigeration. Life cycle assessment (LCA), field measurements, and thermodynamic modeling are all used in this work to offer a thorough analysis of both tunnel types.

The case study facility in Nebraska operates both steam and electric shrink tunnels to …

Hardware And Software Design For A Portable Surgical Training Simulator, Victoria Nelson

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

More than 51 million surgeries are performed on patients annually in the United States. That number grows to 310 million surgeries performed globally each year. Most surgeons go through a minimum of five years of residency – where they train and hone their surgical skills. It is important during this time, and throughout their careers, that they get plenty of practice. Surgical training is time intensive, expensive, and frequently under-resourced. There are finite amounts of surgical training modules for students to share at their facilities. The problem of getting adequate surgical training time continues to exist after surgeons begin their …

Traffic Prediction For Research And Education Networks: Anomaly-Aware Deep Learning And Benchmarking, Mohammad Arafath Uddin Shariff

School of Computing: Dissertations, Theses, and Student Research

Research and Education Networks (RENs) and High-Performance Computing (HPC) environments are critical infrastructures for modern scientific discovery, demanding sustained high-throughput and low-latency data transfers. Unlike commercial networks, RENs exhibit unique traffic characteristics, including predominant “elephant flows,” inherent burstiness, and complex temporal-spatial dynamics often decoupled from human-driven cycles. Traditional traffic forecasting methods, tailored for commercial Wide Area Networks (WANs), consistently fail to capture these distinct REN dynamics, leading to inefficient resource management and potential impediments to scientific progress.

This thesis addresses this critical gap by developing and validating a robust, scalable, and anomaly-aware traffic forecasting framework specifically tailored for REN/HPC networks. …

Low-Level Polarimetric Signatures Of Supercells During Ef3+ Tornado Production, Anthony Noah Began

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Most EF3+ tornadoes are produced by supercells. Understanding of microscale features surrounding intense tornado production remains limited. This research aims to determine commonalities in low-level microphysical processes during intense tornado production via polarimetric radar signature assessment with a Python-based algorithm. Polarimetric variables hypothesized to reflect low-level wind profiles such as the differential reflectivity (Z_DR) arc and the Z_DR–K_DP (specific differential phase) separation vector will be investigated. Supercells which produced EF3+ tornadoes will be examined since these tornadoes pose the highest threat. From 2010 to 2024, the United States recorded approximately 19,100 tornadoes which resulted in …
