Dyno : Dynamic Neurosymbolic Orchestrator For Multi-Agent Systems, Ritvik Garimella, Chathurangi Shyalika, Renjith Prasad, Amit Sheth

Publications

Large Language Model (LLM)-based multi-agent systems (LaMAS) represent an emerging paradigm for tackling complex, multi-step reasoning and decision-making problems. As these systems scale, orchestration, which is the ability to coordinate, manage, and evaluate the interactions among diverse agents, becomes central to their success. While recent orchestrators such as AgentFlow have demonstrated promise in managing communication and task delegation, they remain limited in their ability to understand task semantics, coordinate heterogeneous agent types (e.g., reactive vs. cognitive), and adaptively align outputs with human-defined goals. In this position paper, we introduce the DYNO (Dynamic Neurosymbolic Orchestrator), a system developed as part of …

A Performer's Guide To Selected Trumpet Excerpts Of Orchestral Works By Women Composers, Julia Stowell

University of Kentucky Doctoral Dissertations

Orchestral excerpts are brief passages from symphonic repertoire that are intended to demonstrate a player’s musical and technical abilities. The canon of orchestral trumpet audition excerpts has been relatively unchanged for several generations. This established canon of excerpts rarely features works written by women. As orchestras begin diversifying their programs, the frequently requested orchestral excerpts require new considerations to reflect these changes. In order for excerpts to be reflective of the orchestral canon, they must be updated as the canon changes.

Once an excerpt has been identified and obtained, the next issue is addressing its unique musical and technical challenges. …

Regulating Galaxy Growth: Ionized Gas Conditions, Star Formation Histories, And Environmental Effects, Shweta Jain

University of Kentucky Doctoral Dissertations

Understanding galaxy formation and evolution requires tracing how baryons cycle between stars, gas, and the interstellar medium (ISM) across cosmic time. The efficiency of star formation, the buildup of metals, and the regulation of gas inflows and outflows are governed by evolving physical conditions within galaxies and their environments. My thesis investigates how the ionized ISM, star formation histories, and environmental processes have shaped galaxy evolution over the past ∼ 12 Gyr. The primary focus of this work is the evolution of the physical conditions of ionized gas in galaxies, including gas-phase metallicity and ionization state. Using new and archival …

Phonics And Friends: A Critical Multimodal Discourse Analysis Of Popular Teacher Influencers' Content, Zachary T. Milford

University of Kentucky Doctoral Dissertations

This critical multimodal discourse analysis examined how five teacher-influencers aligned with the Science of Reading (SoR) movement performed authority, constructed discourses, and used affective and semiotic resources in viral TikTok videos about reading instruction. Drawing on Kress and van Leeuwen's (2001) multimodal social semiotics, Fairclough's (1992) critical discourse analysis, Foucault's (1977, 1982) theorizations of power, Papacharissi's (2014) theory of affective publics, Ong's (1982) secondary orality, and Taussig's (1993) mimesis and alterity, this interpretive, qualitative, multiple-case study analyzed fifty viral TikTok videos and four semi-structured interviews with teacher-influencers. Data were analyzed through within-case and within-mode coding, cross-modal analysis, and cross-case analysis …

Technology-Facilitated Violence And Abuse: Portrayals And Perceptions, Christina S. Walker

University of Kentucky Doctoral Dissertations

In the past, intimate partner violence (IPV) was primarily perpetrated in person. However, due to new mediated communication technologies and capabilities like social media and artificial intelligence (AI), perpetrators can use this technology for various purposes including subjecting others to violence, harassment, and abuse. Such violence can be a form of IPV and is referred to as technology-facilitated violence and abuse (TFVA). TFVA is becoming increasingly prevalent and is encountered by a staggering percent of women. Furthermore, unlike traditional forms of IPV, even men are subjected to TFVA at increasing and disproportionate rates, particularly male teens.

In the current state …

Non-Invasive Digital Restoration Of Damaged Photographic Film Negatives, Ankan Bhattacharyya

University of Kentucky Doctoral Dissertations

Physical restoration of damaged photographic film causes more damage. Also, existing non-invasive digital restoration of film negatives does not produce print-quality optical images. Instead, they produce X-ray projections, which are not the same as optical projections. This thesis addresses these problems and establishes a framework that can digitally restore old, damaged films without the need to open them physically. Virtual Unwrapping is an existing pipeline that has proven itself over the last couple of decades to work on unopenable papyrus scrolls, like the Herculaneum Scrolls. This thesis utilizes the concept of virtual unwrapping to restore damaged photographic film negatives. Due …

Frequency And Phase Synchronization Of Antenna Arrays With Phase Incoherent Microcontrollers, Harley W. Byrd

University of Kentucky Master's Theses

The construction of phased array antennas has traditionally been an expensive and complex task. It has recently been claimed that it is possible to construct high-performance Wi Fi antenna arrays using inexpensive consumer components. Motivated by some limited data available from online presentations of such devices, this thesis covers an attempt to construct a phased-array Wi-Fi antenna using several ESP32 chips, which have native Wi-Fi modulation and demodulation capabilities. While there are many positive aspects associated with utilizing ESP32 chips for this purpose, a key challenge is the inherent phase incoherence of their internal Phase Locked Loops (PLLs). The approach …

The Impact Of Flight Instructor Feedback On Subsequent Instructor Evaluations Of Student Performance, Ayhan Rozyyev, Jennifer E. Thropp

Journal of Aviation/Aerospace Education & Research

This study examines the impact of feedback tone and feedback order on flight instructors’ evaluations of student performance in an aviation training context. Using a 2×2 mixed factorial design, 40 certified flight instructors reviewed fictitious training records and rated students based on feedback that varied in tone (positive vs. negative) and order (positive-first vs. negative-first). Results showed that positive feedback significantly influenced evaluations across all measured dimensions, while feedback order had no significant effect, challenging assumptions about primacy and recency effects. These findings highlight the role of positive reinforcement in shaping instructor evaluations and suggest that structured training environments can …

Impact Of In-Cabin Human Machine Interface Designs On Passenger Trust In Urban Air Mobility, Ricole A. Johnson, Erika E. Gallegos

Journal of Aviation/Aerospace Education & Research

Urban Air Mobility (UAM) presents a promising solution for alleviating urban traffic congestion and enhancing transportation efficiency. However, the widespread acceptance of UAM, particularly sustained ridership of autonomous passenger air vehicles (PAVs), is contingent upon addressing critical human factors for building passenger trust, especially in the absence of a human pilot. This paper evaluates how different in-cabin human-machine interface (HMI) designs affect passenger trust in the aircraft and in-cabin display, situation awareness, and pilot preferences. Forty participants, equally split between early and late technology adopters, completed two simulated flights: a baseline flight with no HMI and a second flight featuring …

Under-Enforcement Of Tribal Land Use Regulations, Ezra Rosser

South Dakota Law Review

This brief Article explores the advantages and disadvantages of the under-enforcement of land use regulations by the Navajo Nation. Though scholarship on economic development, including tribal economic development, tends to emphasize the importance of well-defined and predictable rules, homeowners and entrepreneurs seeking land use permissions confront an environment on the reservation marked by under-enforcement. As this Article shows, the limited resources available to many tribal members help explain the tribe’s decision to selectively under-enforce otherwise required land use permitting processes. The purpose of this Article is to neither praise nor condemn an under-enforcement strategy, but instead to provide a framework …

When A Black Man Is In The Principal’S Office: Black Male Leaders Navigating Racialized Spaces, Phillip Smith

GSE Faculty Publications

This study describes the experiences of fourteen Black male principals or heads of school navigating racialized spaces, including the politics of race, and experienced racism in educational settings as well as in school leadership. Data analysis utilized a critical race theory (CRT) and culturally sensitive methodological and interpretive framework. The data analysis revealed themes associated with identity scrutiny, right to lead, meritocracy and color evasiveness, all falling within the white gaze paradigm. However, the results also suggest a demonstrable pathway for Black leaders to successfully navigate the pitfalls of the white gaze and experienced negative professional and personal reactions to …

Pretrial Justice In Indian Country And Bordertowns-Including Rural Tribal Communities In The Bail Reform Conversation, Jordan Gross

South Dakota Law Review

Pretrial detention rates in the United States are down, except in rural counties. Indigenous people are both over-represented and under-protected in settler-colonial criminal justice systems. Yet the criminal justice needs and experiences of rural and Indigenous people are largely overlooked in criminal justice reform research and discourse. I examined the role of rurality in bail administration in Pretrial Justice in Out-of-the-Way Places – Including Rural Communities in the Bail Reform Conversation. There I explained how bail reform measures centered on urban and suburban needs and demographics fail to address pretrial justice challenges and opportunities unique to rural communities. This Article …

Architecting A Complex Adaptive System Model For Selecting Policies To Reduce Kidney Discard, Lirim Ashiku

Doctoral Dissertations

"The kidney allocation system is a complex, evolving system involving multiple heterogeneous agents. Each agent exhibits emergent behavior that may not fully align with the complex system goals. Therefore, there is a need for a transdisciplinary systems approach to visualize the interdependency among agents and understand the dominant patterns that shape the kidney allocation system.

First, this research presented an incremental hierarchical system engineering approach in identifying the agents’ needs and behaviors toward the complex systems’ goal of maximizing deceased donor kidney utilization and reducing kidney discard. The hierarchical systems approach linked with model-based system engineering aided in eliciting agents’ …

Mid-Infrared Spectroscopy And Machine Learning For Chlorogenic Acid Quantification In Coffee, Deborah Herdt, Felix Wühler, Thomas Kunz, Victoria Schiwek, Sarah Kühnemuth, Brian Gibson, Matthias Rädle

Research Outputs: 2025-Present

To predict chlorogenic acid (CGA) concentration in coffee during roasting, a machine learning algorithm was applied to mid-infrared (MIR) data. A total of 44 roasting samples between 140 and 220 °C, along with an unroasted control, were dry-heated in an eddy current roaster and subsequently ground and measured. CGA concentrations were predicted from MIR spectroscopy data using a multilayer perceptron (MLP) regressor and validated against a high-performance liquid chromatography with diode array detector reference. The algorithm performed spectral preprocessing and selected relevant wavenumber regions. The MLP-based model achieved a high coefficient of determination, outperforming classic peak evaluation, indicating that automated …

Enhanced Pulsar Timing Precision For The Era Of Nanohertz Gravitational Wave Astronomy, Sofia V. Sosa Fiscella

Theses

In 2023, several international collaborations comprising the International Pulsar Timing Array achieved a major scientific milestone with the first detection of a signal in pulsar timing observations consistent with the signature expected from a stochastic gravitational wave background, created by an ensemble of unresolved supermassive black hole binaries in the early Universe. The next breakthrough in the field is expected to be the first detection of a continuous wave from a single such binary, which would allow us to better understand their evolution and that of our Universe. However, this feat will require unprecedented precision in our timing measurements. To …

Dna Landscape Tool: An Interactive Webpage, Kerstyn Gay

Theses

Deoxyribonucleic acid (DNA) is a molecule that carries genetic information that makes up every organism. DNA is typically introduced into the biology curriculum starting in high school and depending on an individual's educational path can continue through college. Although taught frequently during school, elements of DNA can be difficult for students to grasp, due to the different visual representations of DNA found in various resources. For instance, when comparing an illustration of a chemically accurate nucleotide base to an abstract visualization of a chromosome learners often aren’t given enough scaffolding to see how one representation relates to the other, which …

Predicting Undergraduate Fallout And Success, Ammar Ahmed Alzarooni

Theses

Universities need to uncover students who are likely to drop out early and do something about it. It should be easy to find and use this information. This thesis evaluated interpretable machine-learning models (MLMs) for predicting three final student outcomes including Dropout, Enrolled and Graduate, using solely demographic, administrative/financial and first-semester academic variables. Study employed publicly accessible Portuguese UCI student retention dataset (4,424 records) and incorporated end-of-Semester-1 feature window to prevent look-ahead leakage and align with actual advising cycles. We trained and compared models using stratified validation, explicit class-imbalance handling and decision-threshold optimization to make dropout detection most critical factor. …

H2 Matrix Compression For Fast Magnetic Field Post-Processing, Calvin M. Demps

University of Kentucky Master's Theses

Large-scale computational electromagnetic simulations frequently require the assembly of dense system matrices, whose computation time and memory cost grow rapidly with problem size and can render high-resolution simulations impractical. This thesis presents a benchmark of the H² hierarchical matrix method applied to the construction of a coupling matrix that maps magnetization current in a structure to the magnetic field at observation points external to the structure. The underlying field interaction is derived from Maxwell's equations and discretized using a Nyström approach, producing a dense matrix.

The method is benchmarked across various geometries of increasing complexity and for increasing mesh …

Gauge-Invariant Gravitational Wave Polarization In Metric F(R) Gravity With Cosmological Implications, Ramesh Radhakrishnan, David Mcnutt, Delaram Mirfendereski, Alejandro Pinero, Eric Davis, William Julius, Gerald Cleaver

Physics & Astronomy Faculty Publications

We develop a fully gauge-invariant analysis of gravitational-wave polarizations in metric 𝑓⁡(𝑅) gravity with a particular focus on the modified Starobinsky model 𝑓⁡(𝑅) =𝑅 +𝛼⁢𝑅2 −2⁢Λ, whose constant-curvature solution 𝑅𝑑 =4⁢Λ provides a natural de Sitter background for both early- and late-time cosmology. Linearizing the field equations around this background, we derive the Klein–Gordon equation for the curvature perturbation 𝛿⁢𝑅 and show that the scalar propagating mode acquires a mass 𝑚2𝜓 =1/(6⁢𝛼), highlighting how the same scalar degree of freedom governs inflationary dynamics at high curvature and the propagation of gravitational waves in the current accelerating Universe. Using the scalar–vector–tensor …

Hybridization Of Genetic Algorithm, Principal Component Analysis And Deep-Learning For Networks Intrusion Detection Systems, Mostafa A. R. Eltokhy, Hend M. A. Mahmoud, Mohammad Sammany

Trends in advanced sciences and technology

With cyber-attacks on the rise, the demand for precise and efficient Intrusion Detection Systems (IDS) is more critical than ever. Traditional machine learning methods struggle with high false alarm and poor detection rates. IDS are crucial for creating secure digital environments by classifying and responding to network intrusions. However, the large volume of inputs for classification often leads to reduced accuracy and misclassification errors. To address this problem, Principal Component Analysis (PCA) is used to optimize the number of classifier inputs, enhancing simplicity without compromising accuracy. A significant challenge in PCA for feature selection lies in determining the best cutoff …

Structural and optical properties were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and UV–Vis spectroscopy, while surface wettability was evaluated through water contact angle measurements. XRD confirmed the formation of pure anatase TiO₂, while FTIR spectra verified the presence of Ti–O and Ti–O–Ti bonds. Wettability analysis showed that films prepared with the lowest precursor concentration exhibited the …

Freedom Of Tribal Association, Andrea Nishi

South Dakota Law Review

In Morton v. Mancari, the Supreme Court upheld a statute granting hiring preference to Indian candidates on the grounds that it did so not on the basis of race but on the basis of affiliation with a tribe as a political entity. As the Court recognized, if such a law were struck down on equal protection grounds, the basis for all federal policy protecting Indian interests would be undermined. In Mancari, this reasoning was used to uphold a law that benefitted Indian candidates pursuant to the federal government’s recognized trust responsibility to Indian tribes. The logic of Mancari has since …

Artificial Intelligence, Tribal Sovereignty, And The Criminal Justice System, Kevin Angelo Brown

South Dakota Law Review

As artificial intelligence (“AI”) has become increasingly integrated into everyday life in Indian Country and into governmental functions, including policing, courts, and corrections, it is creating new circumstances that can undermine tribal sovereignty. The 575 federally recognized Tribal Nations are under significant pressure to maintain their sovereignty while adapting to new AI-based technologies. With the implementation of AI, tribes should retain control over how it is used to benefit their communities, without compromising their legal rights or well-being, particularly in light of past harms caused by inadequate legal protections that allowed technological developments to damage tribal health, environments, economies, and …

Poincaré Invariance And The Unruh Effect, Alexandre Deur, Stanley J. Brodsky, Craig D. Roberts, Balša Terzić

Physics Faculty Publications

In quantum field theory, the vacuum is popularly considered to be a complex medium populated with virtual particle + antiparticle pairs. To an observer experiencing uniform acceleration, it is generally held that these virtual particles become real, appearing as a gas at a temperature that grows with the acceleration. This is the Unruh effect. However, it has been shown that vacuum complexity is an artifact produced by treating quantum field theory in a manner that does not manifestly enforce causality. Choosing a quantization approach that patently enforces causality, the quantum field theory vacuum is barren, bereft even of virtual particles. …
