A Study On Effect Of Information From Navigation System On Driving Behavior, Mio Suzuki, Shota Moriya

Kentucky Transportation Center Presentations

In recent years, navigation services using smartphone applications have become common, and while the number of users is increasing, accidents and violations have begun to occur due to drivers being so focused on obtaining information that they cannot see their surroundings or the information itself is incorrect. Therefore, this study focuses on the fact that stress on drivers caused by such guidance can also be a cause of accidents, and aims to understand the understandability of information and driving behavior of navigation systems and stress by using a driving simulator. From the questionnaire survey by the users, it was found …

An Exploratory Analysis Of Fatal Vehicle Crashes In Urban And Rural Kansas In Relation To Identified Golder Hour Gaps In Hospital Coverage, Mason W. Lipford, Grace N. Whisler Lipford, Gregory L. Newmark, Eric J. Fitzsimmons

Kentucky Transportation Center Presentations

The state of Kansas is a relatively rural state with a majority of highway/interstate miles through farmland and low populated areas. These rural areas can be hot spots for crashes to occur and the lack of hospitals and emergency response nearby can make these types of crashes turn deadly. Few studies have been done on this topic especially for the state of Kansas. As the Department of Transportation is pushing to the “Drive to Zero” goal, pinpointing the harmful factors to indicate where improvements are needed to reduce the number, and severity of crashes is an important first step. Using …

Analyses And Reconstructions Of Crash Scenarios For Class 8, Long-Haul Trucks, Monish Dev Sudhakhar, Rohan Khaire, Jeffrey Wishart, Yan Chen

Kentucky Transportation Center Presentations

Knowledge and analysis of crash scenarios from naturalistic driving data can provide insight into the causes of crashes and thus motivate or benefit the future design of automated driving systems (ADSs). The circumstances commonly resulting in crashes for human-driven, light-duty vehicles were previously compiled into the 37 pre-crash scenarios by NHTSA [1]. However, crash analyses and reconstructions for Class 8 long-haul trucks have not yet been explored in the literature. The Crash Investigation Sampling System (CISS) database has been used as the crash data source for compiling a dataset containing details on a nationally representative sample of thousands of heavy-duty …

Exploratory Prompting Of Large Language Models To Act As Co-Pilots For Augmenting Business Process Work In Document Classification, Jose Ramon Ilagan, Joseph Benjamin R. Ilagan, Claire Louisse Basallo, Zachary Matthew Alabastro

Quantitative Methods and Information Technology Faculty Publications

Businesses deal with different types of documents containing unstructured documents. The data in these documents must be converted into digital forms other automated systems could only process. One generic use case is document classification, which usually involves manual transformation due to human understanding needed in the process. These documents go beyond those generated through regular business transactions and operations and also include web-based content such as online news, blogs, e-mails, and various digital libraries. Recent developments in robotic process automation (RPA) and artificial intelligence (AI) aim to automate the otherwise expensive, time-consuming, and repetitive manual steps. Through more powerful natural …

Compton Scattering Of Mammographic Soft X-Ray Beams By Alkali And Transition Metal Salt Filters Produce X-Ray Interference Zones That May Have Treatment Potential For Localized Cancer Lesions, Subhendra N. Sarkar, Eric Lobel, Sabina Rakhmatova, Derbie Desir, Somdat Kissoon, Daler Djuraev, Katie Tam

Publications and Research

In breast x-ray imaging scattered radiation adds 50% of harmful radiation dose from anisotropic Compton scattering mechanism. We have been working with double layered inorganic salt materials that can induce Compton scattering to the incident mammographic x ray beams (in 20-30 kVp range) with adequate isotropy (angular control). Typically metal nitrates and alkali halide salt layers are shown here to cause low energy radiation interference zones with high and low photon intensities and local flux heterogeneity in terms of flux covariance. Spatial variation of low energy photon flux creates concentrated and sparse radiation zones that may be used to induce …

Geodatabase And Automation Code Used For Past And Real-Time Dynamic Landslide Hazard Maps In Eastern Kentucky, Nathaniel O'Leary, L. Sebastian Bryson, Jason M. Dortch

Earth and Environmental Sciences Research Data

We developed spatiotemporal landslide hazard maps (LHMs) using soil, hydrologic, and geomorphic parameters from the subaerial infinite slope factor of safety (FS) equation under unsaturated conditions. Soil properties were sourced from the NRCS WSS, while geomorphic variables were derived from a 1.5 m LiDAR-based DEM and ArcGIS Online. Soil moisture from Hydrus-1D, driven by precipitation and evapotranspiration (ET) data from Irrigation Manager, introduced temporal variability. Validation against known landslide sites demonstrated FS accuracy both spatially and temporally, despite some false positives. To reduce false positives and enhance slope stability representation, novel depth-to-bedrock (DTB) and soil root cohesion maps were incorporated …

Earth and Environmental Sciences Faculty Publications

For many years, urban sciences relied heavily on traditional, authoritative data sources. However, a paradigm shift has occurred recently with the advent of citizen-driven data contribution. This evolution in data acquisition for urban science is attributable to advancements in positioning and navigation technologies, widespread use of digital devices, the rise of Web 2.0, enhanced broadband communications, and refined data management techniques. The significance of crowdsourced geospatial data in the realm of urban sciences is now widely acknowledged. A diverse array of novel data sources has been increasingly gaining prominence. These include, but are not limited to, social media platforms, street …

Wip: “We Just Did That”: Building Engineering Identity And Sense Of Belonging Through Team Accomplishment In First-Year Design Projects, Leah Maykish, Jessica E.S. Swenson, Eunsil Lee, Emma Treadway

Engineering Faculty Research

This work in progress research paper explores the ways that team-based design-build-compete projects may build engineering identity and a sense of belonging during the first year of an undergraduate engineering program. We analyzed end of semester retrospective interviews of students to identify instances of the quantity and quality of interaction criteria for developing a sense of belonging and the performance and recognition factors for developing engineering identity. Early findings suggest that the design project provides opportunities to develop both identity and sense of belonging. Additionally, a sense of belonging may have helped students to buffer negative performance and recognition to …

Classification Of Sow Postures Using Convolutional Neural Network And Depth Images, Md Towfiqur Rahman, Tami M. Brown-Brandl, Gary A. Rohrer, Sudhendu R. Sharma, Yeyin Shi

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The United States swine industry reports an average preweaning mortality of approximately 16% where approximately 6% of them are attributed to piglets overlayed by sows. Detecting postural transitions and estimating sows’ time budgets for different postures are valuable information for breeders and engineering design of farrowing facilities to eventually reduce piglet death. Computer vision tools can help monitor changes in animal posture accurately and efficiently. To create a more robust system and eliminate varying lighting issues within a day including daytime/ nighttime differences, there is an advantage to using depth cameras over digital cameras. In this study, a computer vision …
