Investigation Of Software Defined Radio And Deep Learning For Ground Penetrating Radar, Yan Zhang
Investigation Of Software Defined Radio And Deep Learning For Ground Penetrating Radar, Yan Zhang
Graduate College Dissertations and Theses
Ground Penetrating Radar (GPR) is a non-invasive geophysical method that uses radar pulses to image the subsurface. This technology is widely used to detect and map subsurface structures, utilities, and features without the need for physical excavation. Traditional GPR systems, which rely on fixed radio frequency electronics like Application-Specific Integrated Circuits (ASICs), have significant limitations in their flexibility and adaptability. Adjusting operational parameters such as waveform, frequency, and modulation schemes is challenging, which is crucial for tailoring performance to specific tasks or conditions. The considerable size and weight of these systems restrict their applicability in harsh or confined spaces where …

Capacitive Voltage Converter Method For The Search Of Water Ice On Celestial Bodies, Nathan Raymond
Graduate College Dissertations and Theses
Electrical Capacitance Tomography (ECT) is an advanced imaging technique used to map the permittivity of dielectric materials. ECT has diverse uses across various engineering fields, including industrial pipelines, the oil and gas sector, chemical manufacturing, and process monitoring, particularly for analyzing fluid flows. ECT can also be applied as a form of dielectric spectroscopy by measuring the response of materials under test (MUT) to changes in frequency, allowing for a detailed study of permittivity variations in a medium.One of NASA's Artemis missions is to locate and utilize in-situ resources. Transporting water to space is prohibitively expensive, with costs of $20,000 …

Enhancing Grid Reliability With Coordination And Control Of Distributed Energy Resources, Hani Mavalizadeh
Graduate College Dissertations and Theses
The growing utilization of renewable energy resources (RES) within power systems has brought about new challenges due to the inherent uncertainty associated with RES, which makes it challenging to accurately forecast available generation. Further- more, the replacement of synchronous machines with inverter-based RES results in a reduction of power system inertia, complicating the task of maintaining a balance between generation and consumption. In this dissertation, coordinating Distributed Energy Resources (DER) is presented as a viable solution to these challenges.DERs have the potential to offer different ancillary services such as fast frequency response (FFR) when efficiently coordinated. However, the practical implementation …
