Analyzing Sedentism in the Built Environment: A Case Study in Archaeological Geophysics at Boundary Village, Uintah County, Utah
Get PDFThis thesis presents a case study that evaluates the ability of near-surface remote sensing to generate archaeological data suitable to answer questions about human behavior. Specifically, this project assesses the ability of two remote sensing methods, ground-penetrating radar (GPR) and magnetic gradiometry to resolve subsurface archaeological features that are markers of sedentism. In this study, the markers of sedentism are features of village sites where their variability is linked to the anticipated and actual length of time spent occupying a domestic site. A comparative dataset was generated to assess how specific subsurface archaeological features would look in GPR and magnetic data sets in the Intermountain West. A Fremont-period pithouse village site was used as a case study to test GPR and magnetic gradiometry. The generated data was then evaluated based on the relationship between the built environment and sedentism. Remote sensing results indicate that postholes and pit features were more identifiable than pithouses, ancient living surfaces, or activity areas. Additionally, magnetic data expectations were not met. The results yielded insight into near-surface remote sensing in the Intermountain West, theory building in geophysical archaeology, and justify further research into the relationship between storage and mobility in prehistoric archaeology
Warming a Calf
Get PDFCalves born in the winter or spring are often exposed to harsh weather and environmental conditions. After birth, calves may become chilled due to cold temperatures or not being dried off promptly. A chilled calf may be experiencing hypothermia. This fact sheet explains the different types of hypothermia and methods for warming a calf until it can be safely returned outside
The TRGB–SBF Project: Creating a New Distance Ladder With Surface Brightness Fluctuations
No full textMany current observational methods to measure the expansion rate of the universe (H0) rely on the same zero-point calibrations. Values of the Hubble constant derived from those local calibrations are in conflict with the predicted value of H0 from the successful ΛCDM cosmological model, resulting in the Hubble tension. In order to decrease systematic uncertainties, and to address this tension, we have created a new and independent sequence of distance measurement techniques. We have used James Webb Space Telescope (JWST) tip of the red giant branch (TRGB) distances to 14 giant elliptical galaxies that we used as calibrators for surface brightness fluctuation (SBF) distances. These TRGB distances replace the calibration previously occupied by Cepheid variable stars. We present a new calibration of the SBF distance scale using DECam optical colors and the TRGB zero point and show how it affects previous SBF measurements of the Hubble Constant
Far-Field UAV-Enabled Antenna Radiation Pattern Mapping
No full textThis paper presents an overview of an research project at Weber State University (WSU) focused on developing a UAV-based system for measuring far-field radiation patterns of physically large antennas operating in the High-Frequency (HF, 3–30 MHz) and Very-High-Frequency (VHF, 30–300 MHz) ranges. Leveraging commercially available unmanned aerial systems (sUAS) components, software-defined radios (SDRs), open-source software tools, and advanced simulation environments, this project aims to create a cost-effective, scalable measurement solution that addresses the logistical challenges of traditional methods. By enabling autonomous three-dimensional radiation mapping of operational antennas in open-field environments, the proposed system refines industry practices and expands our understanding of ground interactions and directivity effects on in-environment antenna performance
Bi-Level Route Optimization and Path Planning With Hazard Exploration
No full textEffective risk monitoring in dynamic environments such as disaster zones requires an adaptive exploration strategy to detect hidden threats. We propose a bi-level unmanned aerial vehicle (UAV) monitoring strategy that efficiently integrates high-level route optimization with low-level path planning for known and unknown hazards. At the high level, we formulate the route optimization as a vehicle routing problem (VRP) to determine the optimal sequence for visiting known hazard locations. To strategically incorporate exploration efficiency, we introduce an edge-based centroidal Voronoi tessellation (CVT), which refines baseline routes using pseudo-nodes and allocates path budgets based on the UAV\u27s battery capacity using a line segment Voronoi diagram. At the low level, path planning maximizes information gain within the allocated path budget by generating kinematically feasible B-spline trajectories. Bayesian interference is applied to dynamically update hazard probabilities, enabling the UAVs to prioritize unexplored regions. Simulation results demonstrate that edge-based CVT improves spatial coverage and route uniformity compared to the node-based method. Additionally, our optimized path planning consistently outperforms baselines in hazard discovery rates across a diverse set of scenarios

Controllers and Control Insights for a Bio-Inspired Rotating Empennage Fighter Aircraft
No full textOne method to improve aerodynamic efficiency in fighter aircraft is to remove the vertical tail. Removing the tail, however, causes complications in terms of control. If the tail is allowed to rotate for control, multiple trim solutions arise, where traditional aircraft generally only have one trim solution for a given flight condition. In the present work various control methodologies are studied for controlling a rotating tail fighter aircraft. Through analyzing these controllers it is found that, without modifying the BIRE aircraft, some minimum amount of lift must be carried on the tail for control to be successful, given common handling qualities and maneuvering metrics for fighter aircraft. If the center of gravity is shifted 1 ft forward, acceptable control performance is achieved as evaluated from fighter aircraft performance metrics. Despite the increased lift carried on the tail with the center of gravity shifted forward, the BIRE aircraft has lower drag than the baseline aircraft over a significant portion of the flight envelope
