Precise Point Positioning Inertial Navigation Integration For Kinematic Airborne Applications, Ryan Watson

Graduate Theses, Dissertations, and Problem Reports (ETD)

UAVs have the potential for autonomous airborne remote sensing applications that require rapid response to natural hazards (e.g. volcano eruptions, earthquakes). As these applications require very accurate positioning, tightly coupled Global Positioning System (GPS) Precise Point Positioning (PPP) Inertial Navigation Systems (INS) are an attractive method to perform real-time aircraft positioning. In particular, PPP can achieve a level of positioning accuracy that is similar to Real-Time Kinematic (RTK) GPS, without the need of a relatively close GPS reference station. However, the PPP method is known to converge to accurate positioning estimate more slowly when compared to RTK, a drawback of …

Empirical Genetic Algorithm Parameter Tuning Concerning The Synthesis Of Combinational Logic Circuits, Joshua Ward

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study identifies optimal parameter values for a genetic algorithm used in the synthesis of combinational logic circuits. Parameters used to obtain an initial solution circuit are examined as well as parameters used to optimize solution circuits. Finding an initial solution circuit was done using a fitness function that was less influential while optimizing solution circuits used a stronger fitness function. This allowed parameters to be studied under very different circumstances. It was discovered that parameters which maintained a higher genetic diversity and strayed farther from the concept of "Survival of the Fittest" produced better results in general.

Storage Capacity Estimation Of Commercial Scale Injection And Storage Of Co2 In The Jacksonburg-Stringtown Oil Field, West Virginia, Zhi Zhong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Geological capture, utilization and storage (CCUS) of carbon dioxide (CO2) in depleted oil and gas reservoirs is one method to reduce greenhouse gas emissions with enhanced oil recovery (EOR) and extending the life of the field. Therefore CCUS coupled with EOR is considered to be an economic approach to demonstration of commercial-scale injection and storage of anthropogenic CO2. Several critical issues should be taken into account prior to injecting large volumes of CO2, such as storage capacity, project duration and long-term containment. Reservoir characterization and 3D geological modeling are the best way to estimate the theoretical CO 2 storage capacity …

Phosphorus Determination In Forage And Manure Using Portable X-Ray Fluorescence Spectroscopy To Support Comprehensive Nutrient Management Planning, Yadav Sapkota

Graduate Theses, Dissertations, and Problem Reports (ETD)

Phosphorus (P) runoff from agricultural fields is a major cause of water quality degradation problems. A P mass balance across the farm could maintain profitability and sustainability of animal-based farms and minimize water quality problems. Comprehensive Nutrient Management Plans (CNMPs) require mineral composition, especially P, data on soil, forage, and manure samples for accurate planning. However, traditional wet chemical methods of P determination are costly, time-consuming, and generate hazardous waste. X-ray fluorescence (XRF) could overcome many of these disadvantages and allow rapid determination of P concentrations. Portable XRF (PXRF) units are Energy Dispersive (ED) systems with low power X-ray tubes …

Comparing Fixed-Amount And Progressive-Amount Dro Schedules For Tic Suppression In Youth With Chronic Tic Disorders, Matthew R. Capriotti, Jennifer E. Turkel, Rachel A. Johnson, Flint M. Espil, Douglas W. Woods

Psychology Faculty Research and Publications

Chronic tic disorders (CTDs) involve motor and/or vocal tics that often cause substantial distress and impairment. Differential reinforcement of other behavior (DRO) schedules of reinforcement produce robust, but incomplete, reductions in tic frequency in youth with CTDs; however, a more robust reduction may be needed to affect durable clinical change. Standard, fixed‐amount DRO schedules have not commonly yielded such reductions, so we evaluated a novel, progressive‐amount DRO schedule, based on its ability to facilitate sustained abstinence from functionally similar behaviors. Five youth with CTDs were exposed to periods of baseline, fixed‐amount DRO (DRO‐F), and progressive‐amount DRO (DRO‐P). Both DRO schedules …
