Experimental And Computational Insights Into Reservoir Rock Mechanics And Petrophysical Properties, Prasad Pothana

Theses and Dissertations

This dissertation investigates the influence of stress, mineralogy, and microstructure on the elastic and transport properties of reservoir rocks. A multi-scale framework integrating laboratory measurements, petrophysical inversion, and discrete-element simulations is developed to quantify the stress-dependent behavior of heterogeneous sedimentary formations relevant to hydrocarbon production and CO2 sequestration.

Core-scale experiments quantify velocity–effective stress and permeability–effective stress relationships in tight siliciclastic and mixed lithologies. Results demonstrate that pore-throat collapse and microcrack closure under confining stress cause systematic reductions in permeability and acoustic velocities. The derived empirical functions provide predictive capability for estimating in-situ stress effects on reservoir performance and time-lapse seismic …

Microbial Communities And Host Plants Of Megachilidae In The Greater Grand Forks Area (Ggfa), Sara Margit Wallace

Theses and Dissertations

Although Megachilidae are important pollinators in the United States, there is still much to learn about the health and functionality of these bees. Megachilids are threatened by competition from non-native pollinators and other environmental factors. The species distribution and composition of the gut microbiome in megachilid bees are not well known for the Greater Grand Forks Area (GGFA). My research seeks to answer the questions: what megachilid species are in the GGFA, where are they, and what symbionts are in their gut microbiomes? I collected and identified solitary bee specimens from North Dakota and Minnesota, dissected their gut contents, and …

Examining The Utility Of Haptic Feedback To Improve Pilot Situational Awareness & Performance: A Psychophysiological Approach, Jessica Van Bree

Theses and Dissertations

Pilot situational awareness (SA) has been deemed to be a critical component of flight efficacy, efficiency, and overall mission success. Studies have shown that several incidents and accidents have been the result of level-one SA errors, meaning that members of the flight crew have failed to accurately perceive the elements in their environments. As such, several strategies have been investigated to improve pilot SA. One potential avenue of research is the addition of haptics in to the flight deck. In some studies, the implementation of haptics have shown to improve piloting tasks, pilot safety, and aircraft control. The current study …

Elucidating The Oxidation Mechanisms In Cr2alb2 Using Density Functional Theory And Thermodynamic Modeling, Ushan Asela Adhikarige

Theses and Dissertations

This thesis investigates the oxidation behavior of Cr2AlB2 surfaces using density functional theory calculations combined with thermodynamic modeling. Our analysis encompassed surface stability assessments, oxygen adsorption studies on various surfaces, and thermodynamic insights into oxidation mechanisms. Surface stability assessments reveal that the (010) surface terminated with an Al layer exhibits the lowest surface energy. Oxygen adsorption studies on the (010), (111), and (021) surfaces demonstrate strong dissociative adsorption with binding energies ranging from -4.72 to -4.22 eV depending on coverage. Thermodynamic analysis shows that elevated temperatures reduce oxidation favorability, while increased oxygen partial pressure enhances it. The study reveals that …

Road Surface And Subsurface Monitoring Using Machine Learning, Koduah Amoako

Theses and Dissertations

This thesis presents a comprehensive, non-invasive framework for real-time monitoring of road surface and subgrade conditions using acoustic sensing and machine learning. Traditional Tire-Road Coefficient of Friction (TRCF) estimation techniques often rely on intrusive sensors, offline data analysis, or laboratory measurements, making them impractical for real-time applications. The present research introduces an alternative approach that utilizes the acoustic emissions generated by tire-road interaction to infer both surface friction and subsurface integrity dynamically.Measurement microphones were mounted beneath a test vehicle to record tire-road noise signatures across different pavement textures and vehicle speeds. The collected acoustic signals were processed using Fast Fourier …

Integration Of Fluorescence Imaging And Advanced Analytical Techniques For Reliable Contamination Detection, Mahsa Aliee

Theses and Dissertations

Effective surface contamination detection in food processing and healthcare environments is hindered by the limitations of visual inspection and ATP bioluminescence testing, both of which struggle to identify thin, transparent, or spatially irregular organic residues. These constraints contribute to inconsistent hygiene verification and create a need for objective, scalable, and real-time detection methods capable of operating under variable environmental conditions.

This dissertation develops an integrated framework that combines UV-induced fluorescence imaging with advanced analytical techniques to improve contamination detection reliability.

The Impacts Of Hydrometeor Centrifuging On Numerical Simulations Of Supercells And Tornado-Like Vortices, Ronald Stenz

Theses and Dissertations

Supercell simulations capable of resolving a tornado-like vortex (TLV) have typically ignored hydrometeor centrifuging, resulting in the unrealistic buildup of precipitation in the center of TLVs. To improve the realism of numerical simulations of supercells and their resulting TLVs, an algorithm to parameterize bulk hydrometeor centrifuging was incorporated into an idealized cloud model. Simple idealized vortex simulations and simulations of supercells producing TLVs were analyzed to determine the impacts of hydrometeor centrifuging on numerically simulated supercells and TLVs. The inclusion of hydrometeor centrifuging does not appear to directly impact the intensity and duration of supercell spawned TLVs. Although precipitation minima …

Investigation Of Wireless Communication Sub-Optimizing Factors And Ai-Based Optimization For Ber Reduction, Lalan Jee Mishra

Theses and Dissertations

The increasing demand for high-throughput, low-latency, and reliable wireless communication has led to significant advancements of cellular wireless technologies since the early ‘80s. However, in dynamic and interference-prone environments—particularly those involving Unmanned Aerial Vehicles (UAVs)—signal degradation due to pathloss, multipath propagation, co-channel interference, and weather-induced attenuation continues to undermine performance. These factors contribute to elevated bit error rates (BER), inefficient spectrum usage, and unreliable communication links, thereby limiting the practical utility of wireless systems in aerial applications. Traditional mitigation techniques, while effective under certain conditions, often fail to adapt to rapidly changing wireless environments. This shortcoming underscores the need for …
