Real-Time Cyber-Power Testbed Enhancement And Synchrophasor Data Generation For Anomaly Detection Using Physics-Informed Machine Learning, Vasavi Sivaramakrishnan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Advanced sensing and automation are essential to managing the evolving electric power system with tight coupling of information and power system layer. However, this increasing number of cyber-physical devices brings vulnerabilities from cyber threats and extreme weather events can endanger the power system on a physical level as well. Advanced monitoring and control algorithms with human operators in the loop are needed to enable power system resiliency despite these increasing threats. These advanced algorithms require validation using a realistic test system that mimics real-world scenarios.

This work focuses on a) developing a realistic real-time cyber-power testbed with hardware-in-the-loop to generate …

Venus Balloon Localization: A Map-Aided Navigation Approach Supported By A Single-Satellite, Heath Scott Cottrill

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although Venus and Earth began as twins, possessing comparable size, mass, and composition, past exploration missions have revealed that Venus is now hellishly hot, devoid of oceans, and enveloped in a carbon dioxide-filled atmosphere. To understand when and why this evolutionary divergence occurred, further exploration is required. Today, there is a growing interest in the use of aerial platforms to circumvent the harsh conditions at the surface, which limit the lifetime of landed instruments. In this concept, a single balloon, propelled by the ambient wind field, would operate in the atmosphere at an altitude between 50 and 70 km, where …

Evaluating The Efficacy Of The Archaeal Proteasome To Alleviate Protein-Misfolding Retinopathy, Celine Brooks

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nearly all neurodegenerative diseases (NDs) and some eye diseases are characterized by the presence of misfolded and aggregated proteins. The ubiquitin proteasome system (UPS) is responsible for degrading the majority of proteins including misfolded and aggregated proteins. However, in NDs the performance of the UPS is impaired, and this impairment partially comes from these protein aggregates inhibiting the proteasome. This inhibition leads to an accumulation of protein aggregates, more proteasomal inhibition, and fewer chaperones for newly synthesized proteins, triggering a collapse in proteostasis, which is thought to contribute to the pathogenesis of NDs. Consequently, stimulating proteasome function is being investigated …

Triggered Online System Re-Identification Applied To Model Predictive Control Using Gaussian Processes, Daniel Augusto Kestering

Graduate Theses, Dissertations, and Problem Reports (ETD)

Safety, product quality, enhanced performance, and increased profit all depend on the control of chemical and energy processes. However, operational issues can lead to control challenges, especially when processes are subject to disturbances during their operation. Process control methods work best when processes operate close to their designed operat- ing conditions, but lack of performance or other issues may occur when the process is far from such conditions. To overcome these challenges, in this dissertation, online model re- identification is proposed for Model Predictive Control (MPC). This involves reassessing the predictive model of an advanced controller, namely MPC, when re-identification …

A Floquet Solver For Time Periodic Open Quantum Systems, Fenton Ross Clawson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Computational physics has been a backbone of experimental and theoretical physics since the 1940’s, when the first nuclear bomb and ballistic simulations were per- formed at Los Alamos Laboratory. Nowadays, however, simulation of open quan- tum systems has been formalized into coding packages and user-friendly functions, such as QuTiP or Qiskit, which allow users to simulate these systems without hav- ing the in-depth knowledge required to build the computational backbone from the ground-up. With the shift in modern quantum physics towards the realization of quantum computation, a strong computational background is still necessary to lend validity to theoretical results and …

Analysis Of Pulsar Discoveries And Pulse Profile Variability: From Pulsar Candidates To Gravitational Wave Detector, William Carl Fiore

Graduate Theses, Dissertations, and Problem Reports (ETD)

Last year, pulsar timing arrays (PTAs) reported evidence of a gravitational-wave (GW) background at nanohertz frequencies, opening a new window into the Universe. PTAs measure GW-induced variations in the timing of radio pulses from millisecond pulsars (MSPs) in our Galaxy. In order for PTA experiments to confidently detect and characterize the GW background, they must continue to regularly observe many MSPs and measure their pulse times of arrival as precisely as possible. This motivates efforts to find new MSPs with pulsar surveys, and to study pulsars whose unusual behavior may give rise to excess noise in PTA data sets, potentially …

Investigating The Effect Of Sign-Tracking On Attention And Perceptual Inference, Maria C. Potts

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous research has shown that animals vary in the degree to which they attribute incentive salience to reward predictive cues. In Pavlovian conditioning, two behavioral phenotypes emerge: goal-tracking (GT), in which animals approach the site of the reward, and sign-tracking (ST), in which animals approach the conditioned stimulus and interact with it as if it has become a reward in its own right. ST has been associated with higher rates of impulsivity, drug reinstatement, and relapse, and is thought to confer addiction vulnerability. Though some studies have suggested that similar phenotypes exist in humans and are possibly related to addiction …

Aberrant Lipid Accumulation And Retinal Pigment Epithelium Dysfunction In Prcd-Deficient Mice, Sree Indrani Motipally

Graduate Theses, Dissertations, and Problem Reports (ETD)

Progressive Rod-Cone Degeneration (PRCD) is a peripheral membrane protein predominantly expressed in photoreceptor outer segment (OS) disc membranes with an unknown function. Several mutations in Prcd are implicated in Retinitis pigmentosa (RP) in humans. The most common “cysteine to tyrosine” (C2Y) mutation in Prcd leads to progressive retinal atrophy in multiple dog breeds and RP in humans. Canine models harboring the C2Y mutation in Prcd show disorganized OS structure with greatly attenuated photoreceptor OS renewal rates. Recent studies show defects in the photoreceptor nascent disc flattening in the absence of Prcd. However, it is unclear how OS discs eventually …

An Investigation Of Relations Between Developmental Stage, Impulsivity, And False Confessions, Madison G. Gallimore

Graduate Theses, Dissertations, and Problem Reports (ETD)

The current study examined relations between developmental stage, impulsivity, and false confessions. Based on the findings from Tervo-Clemmens et al. (2023), participants were divided into two groups based on age; ages included those who had not yet reached executive functioning maturation (12-to-20-years-old) and those who had reached executive functioning maturation (21-to-37-years-old). Impulsiveness was determined by performance on a delay-discounting task based on Mok et al. (2020) and the Barratt Impulsivity Scale-11 (BIS-11) Self-control subscale. False confessions were measured based on whether participants orally admitted to a minor wrongdoing. All participants experienced the same study procedure. The false confession paradigm utilized …

The Search, The Localization, And The Characterization: Fast Radio Transients, Reshma Anna Thomas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fast radio transients are energetic bursts in centimeter or meter wave-lengths, lasting only milliseconds, and originating from both Galactic and extra-Galactic sources. In our Galaxy, these transients primarily originate from pulsars, which are rotating neutron stars. The more energetic extra-galactic transients, known as fast radio bursts (FRBs), have unknown origins. This thesis explores various techniques, including single dish and interferometric observations, to detect and accurately localize fast radio transients. It also investigates how the propagation effects of radio waves can reveal characteristics of the local environment and potential FRB sources. Furthermore, it demonstrates how FRBs can be used to study …

Fingerphoto Deblurring Using Wavelet Style Transfer, David Connard Keaton

Graduate Theses, Dissertations, and Problem Reports (ETD)

This work focuses on a deblurring network designed specifically for the task of deblurring contactless fingerprints, a.k.a fingerphotos. This network takes the general idea of style transfer, and applies it to the realm of deblurring. The standard use case for style transfer networks is artistic style transfer, which is used for recreational purposes. For this work, though, style transfer is used in the context of deblurring. Since style transfer can transfer artistic styles from one image to another, who's to say it can’t transfer clarity and sharpness as well? This is the focus of this work; taking a blurry fingerphoto, …

Advances In Machine Learning Aided Seismic Interpretation And Inversion For Subsurface Characterization, Tobi Micheal Ore

Graduate Theses, Dissertations, and Problem Reports (ETD)

Geophysical data are used to “remotely sense” the subsurface to illuminate structures, stratigraphy, and features that are of interest in the exploration for energy, suitable storage for carbon dioxide, geothermal development, and environmental considerations. The interpretations of these data typically are regarded as partially an art, as it depends on the experience of the interpreter. This is further exacerbated with the big data era as this data is large and takes several days, even longer, to manually interpret. To bridge this gap of speed and subjective bias, machine learning has been successfully applied to automate the geophysical interpretation process. This …

Investigating The Effect Of Using Humorous Threats In Recreation Area Rules Signage To Influence Behavioral Intentions, Jacob Timothy Vargas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Communicating the importance of rules and warnings to visitors of recreational parks through signage can be difficult. However, it is one of the most important things to keep visitors safe. Oftentimes, these signs use fear of punishment or injury to discourage certain behaviors. According to studies following the Extended Parallel Processing Model (EPPM), using threats can backfire and cause visitors to use maladaptive fear responses to counteract a threat message if the content is too extreme or too psychologically close. Humor is a versatile tool that can be used to grab attention, temper perceptions, and influence decision-making. Comedians like Jon …

The Names Of All Wild Things: Field Guides And Environmental Thinking, Frank Izaguirre Phd

Graduate Theses, Dissertations, and Problem Reports (ETD)

The project first traces the earliest origins of natural history writing, surveying how natural history writing from antiquity presented and categorized the living world, and then how the rise of print culture and growing popularity of natural history writing would facilitate the rise of European empires. Values and conventions emerged that would later feed into the field guide, like the pairing of text and illustration to aid identification and the decontextualizing of plants and animals from their environments.

Near the end of the nineteenth century, the field guide genre emerged. Some wildly popular books, mostly written by women, emphasized the …
