Continuous Query For Top-K Maximal Sum Intervals Over Streaming Data, Zhongshuai Zhang, Xiaochun Yang, Baihua Zheng, Rui Zhu, Haomin Li, Bin Wang

Research Collection School Of Computing and Information Systems

The continuous identification of top-k maximal sum intervals using a sliding window over a data stream is a critical operation for applications in IoT and beyond. A maximal sum interval is a non-overlapping, contiguous subsequence with the maximal sum in a sequence of signed values. Existing algorithms are ill-suited for streaming contexts: they either exhaustively enumerate all intervals even for small k values, or depend on indexes that require frequent and costly restructuring. We propose a novel partition-based strategy. Our core insight is a partitioning scheme that guarantees that any maximal sum interval is fully contained within a single partition, …

Timeradar: A Domain-Rotatable Foundation Model For Time Series Anomaly Detection, Hui He, Hezhe Qiao, Yutong Chen, Kun Yi, Guansong Pang

Research Collection School Of Computing and Information Systems

Current time series foundation models (TSFMs) primarily focus on learning prevalent and regular patterns within a predefined time or frequency domain to enable supervised downstream tasks (\eg, forecasting). Consequently, they are often ineffective for inherently unsupervised downstream tasks—such as time series anomaly detection (TSAD), which aims to identify rare, irregular patterns. This limitation arises because such abnormal patterns can closely resemble the regular patterns when presented in the same time/frequency domain. To address this issue, we introduce TimeRadar, an innovative TSFM built in a fractional time–frequency domain to support generalist TSAD across diverse unseen datasets. Our key insight is that …

Task-Aligned Haze Removal With Semantic-Aware Fusion And Contrast Self-Correction, Jinbin Wang, Aiping Yang, Guosong Jiang, Wenlong Yu, Dongwei Ren, Qinghua Hu

Research Collection School Of Computing and Information Systems

Adverse haze conditions introduce complex degradations that obscure scene details and distort structural cues critical for object detection, posing persistent challenges for vision‐based sensing systems. Although existing haze removal methods have achieved notable improvements in visual clarity, their optimisation objectives are often misaligned with downstream detection requirements, leading to limited detection performance in real‐world scenarios. To address this issue, this work proposes a task‐aligned weakly supervised haze removal framework, termed Dehaze4Detection, which explicitly aligns low‐level restoration with high‐level detection objectives. The framework incorporates a Semantic‐Aware Multi‐Scale Fusion Module (SMFM) that embeds pixel‐level semantic knowledge into the dehazing process, enabling selective …

Cross-Layer Security And Responsive Evaluation Architectures For Quantum Resistance In Connected Vehicles, Geoff Twardokus

Theses

Connected vehicle (CV) technologies are emerging as a crucial technology for improving safety on future roadways. Wireless vehicle-to-everything (V2X) communication allows CVs to exchange information that provides enhanced awareness and supports better driving decisions, especially in high-risk or non-line-of-sight scenarios. However, V2X also exposes new surfaces to physical layer attacks and increasingly sophisticated, potentially quantum-capable threat actors. As human or autonomous CV drivers will make split-second safety-critical decisions based on the contents of V2X messages, ensuring their authenticity, as well as their reliable and timely delivery, is crucial. Otherwise, malicious attackers may interfere with safety services or spoof messages to …

Analysis Of Gwtc-3 With Multiple Quasicircular Next-Generationwaveform Models, Noah M. Manning

Theses

The interpretation of gravitational wave sources depends on the specific choice of model used to interpret signals. For example, previous analyses of GWTC-3 event candidates using the SEOBNRv4PHM, IMRPhenomXPHM, and NRSur7dq4 models have arrived at sometimes notably di!erent conclusions about event properties. Unfortunately, subtle analysis settings and code di!erences can also produce notable di!erences in event properties. Previous work on GWTC-3 has not yet used a consistent analysis framework to reassess all events with state-of- the-art models. In this work, we revisit GWTC-3, reassessing every event using three waveform models: two state-of-the-art models (SEOBNRv5PHM and IMRPhenomTPHM) and one older waveform …

The Effect Of Cerebellar Transcranial Direct Current Stimulation On Anxiety, Shivangi Bhardwaj

All-Inclusive List of Electronic Theses and Dissertations

Anxiety is one of the most prevalent mental health disorders in the U.S. Individuals of all ages are affected by anxiety. Therefore, research into anxiety and its potential treatment has constantly been an area of interest. Newer approaches to managing anxiety include non-invasive stimulation techniques, such as Transcranial Direct Current Stimulation (tDCS), because of its accessibility and effectiveness. Past tDCS work typically focused on regions in the frontal lobe. However, tDCS over the cerebellum has not received as much attention compared to the cerebrum, despite recent work demonstrating cerebellar involvement in emotion processing. Thus, a better understanding of how cerebellar …

Hvi-Cidnet+: Beyond Extreme Darkness For Low-Light Image Enhancement, Kangbiao Shi, Xiaowen Ma, Yixu Feng, Tao Hu, Peng Wu, Guansong Pang, Qingsen Yan

Research Collection School Of Computing and Information Systems

Low-Light Image Enhancement (LLIE) aims to recover visually pleasing content and details from degraded low-light images. However, existing RGB-based methods often suffer from color bias and brightness artifacts due to inherent high color sensitivity. Although the HSV color space can decouple brightness and color, it introduces noticeable red and black noise artifacts. To address these challenges, we adopt the Horizontal/Vertical-Intensity (HVI) color space for LLIE, which is defined by the HV color map and learnable intensity. The former enforces small distances for red coordinates to alleviate red noise artifacts, while the latter adaptively compresses low-light regions to suppress black noise …

Continuous Authentication For Industrial System Access: Evaluating Bluetooth Low Energy Direction Finding And Channel Sounding For Tailgating And Relay Attacks, Mitchell Mennelle

LSU New Orleans Theses and Dissertations

In physical access control, authentication is often viewed as a one-time event, where, once an authorized user crosses a protected boundary, downstream systems assume the user remains physically present. Tailgating and relay attacks violate this assumption. In this thesis we propose a continuous authentication layer based on two Bluetooth Low Energy spatial signals. Angle of Arrival direction finding follows the trail of a worn credential to determine when an operator exits a work zone. Bluetooth Channel Sounding measures a physical property of the radio path and verifies distance during stationary periods. Limiting Relay Attacks with Event-Driven Distance Verification. A stream …

Extended Adaptive Oscillator Framework For Gait Phase Estimation With Adaptive Coupling And Transition Detection Across Locomotion Tasks, Nikhila Radha Krishnan

All Theses

Gait phase is a human-inspired physical variable that describes the instantaneous position of a person within a gait cycle. Adaptive oscillators have been widely used for gait phase estimation due to their ability to synchronize with periodic and pseudo-periodic biomechanical signals and generate monotonically increasing cyclic phase values. Typically, the performance of adaptive oscillators is strongly influenced by coupling strength, a parameter that bridges a trade-off between convergence speed and steady-state variability of the estimated stride frequency. In gait assistive applications, stride frequency estimation must be sufficiently fast to enable phase-based assistance while achieving a stable stride frequency estimate. The …

Insect Abundance And Bat Use Of Fields For Foraging In The Cumberland Plateau, Caroline M. Abramowitz

All Theses

Bat populations and their insect prey are declining, making it urgent to understand how habitat features and management support both groups. Early successional habitat (ESH), grasslands and shrublands with reduced vegetative clutter and abundant flowering resources, may benefit foraging bats and nocturnal insects. This study examined how landscape context, patch characteristics, microhabitat features, and management (mechanical mastication and prescribed burns) affected insects and bats across 29 managed fields in Big South Fork National River and Recreation Area (TN/KY) from 2024–2025. Flight-intercept traps collected 25,297 insects across five orders. Though results were order-specific, vegetative composition and height were the strongest predictors …

Trace Element Concentrations In Tissues And Otoliths Of Fishes From Artificial Reefs In The Northern Gulf Of Mexico: The Role Of Size, Age, And Trophic Position, Blaine Savoie

LSU New Orleans Theses and Dissertations

Nearshore artificial reefs and fishes relying on them to forage and refuge can be susceptible to trace element (TE) pollutants from anthropogenic sources. Although some TE are essential, higher concentrations can cause detrimental effects and concern regarding consumption. This study assesses TE accumulation in nearshore reef fishes in the northern Gulf of Mexico, a region influenced by coastal riverine discharge, where fishing has socioeconomic importance. Five fish species from six eco-reefs were collected and analyzed for TE. An inductively coupled plasma mass spectrometer was used to analyze the TE concentrations of muscle, liver, and otoliths. TE concentrations of tissues and …

Comparative Analysis Of Rigging Implementations, John E. Thomas

Master of Fine Arts in Digital Media Culminating Experience

Rigging acts as a bottleneck between modeling and animation, yet core rigging principles and procedures have largely stagnated over the past two decades. However, cutting-edge rigging systems have begun appearing recently in software not typically used for animation. These tools are proposed to mitigate the need for rigging artists. These novel systems now force teams to evaluate what system is best for their projects. Artists have focused their analysis of rigging tools on how they interact with, or compare to, existing pipeline structures, concepts, and deadlines. This research centers on the implementation and development of tools and systems ranging from …

Towards Confucian Economic Democracy: A Relational Alternative To Possessive Individualism, Sor-Hoon Tan

Research Collection School of Social Sciences

This article offers a Confucian conception of ownership and a different approach to equality based on a concept of relational person that could provide an alternative philosophical framework for economic democracy. The Confucian concept of nonexclusive and nonabsolute co-ownership, conditional on owners fulfilling their social responsibilities and sustained in networks of relationships mitigates the drive to appropriation and resistance to redistribution even without formalizing legal rights of equal ownership. Confucian texts’ condemnation of wide disparities between rich and poor corresponds with distributive ideas that balance equal satisfaction of needs with merit-based incentives for productivity constrained by social harmony. Without advocating …

When The Best-Fit Model Is Not Best: The Glass Slipper Fallacy And Latent Growth Mixture Modelling, Jonathan L. Chia, Markus Wettstein, Andree Hartanto

Research Collection School of Social Sciences

Despite the use of latent growth mixture modelling (LGMM) to study longitudinal changes, existing practices may inadvertently impede this very investigation. Although subgroup trajectories may theoretically differ in their structure (e.g., some subgroups being linear, some curvilinear), the current convention advocates overreliance on the baseline model to derive subsequent profile trajectories, which may obscure these structural differences. In this article, we provide a brief description of extant LGMM practices, after which we explicate the pitfalls of the current approach. Finally, we provide a principled approach for LGMM research moving forward. Specifically, we recommend specifying a set of theoretically plausible models …

Artificial Intelligence (Ai) In Forensic Psychology: An Umbrella Review Of Potentials And Pitfalls, Ysabel Thereze Ang Guevarra, Nur Eva Alisha Binte Mohamed Hisham, Andree Hartanto

Research Collection School of Social Sciences

Artificial intelligence (AI) is becoming increasingly embedded within forensic psychological practice, shaping how criminal risk, legal responsibility and public safety are assessed. AI tools are now used in recidivism prediction, behavioural analysis, deception detection and investigative support, high-stakes domains where errors can have profound consequences. Despite this rapid adoption, the existing literature remains fragmented, with most reviews confined to narrow subdomains and offering limited integrated synthesis of AI′s broader role in forensic psychology. Thus, this umbrella review addresses this gap by synthesising findings from 43 reviews obtained from five major databases, namely EBSCOhost ERIC, EBSCOhost PsycInfo, PubMed, Scopus and Web …

The Ambivalent Wisdom Of Moral Disgust, Brandon Yip

Research Collection School of Social Sciences

This paper has two aims. First, to provide a positive account of moral disgust. I suggest that moral disgust is a response to acts that are socially corrosive, namely, acts that undermine the normative structure to which an agent is attuned. I support this analysis with two lines of evidence: (1) moral disgust serves the important function of guarding normative structures from socially corrosive actions and (2) the analysis provides an illuminating explanation of moral disgust in a wide variety of cases. The secondary aim of this paper is to probe the normative implications of my positive account. I suggest …

Misplay Or Malice? Players’ Interpretations Of Poor Gameplay In Competitive Team-Based Multiplayer Online Games, Valerie Yu, Benjamin H. Detenber, Sonny Rosenthal

Research Collection College of Integrative Studies

Research on perceptions of gaming toxicity has focused on its verbal forms, while gameplay-related forms remain relatively understudied. Furthermore, assessments of gameplay actions as toxic may depend on situational considerations. The present study used a controlled experiment to examine player interpretations of gameplay sabotage using pre-recorded gameplay scenarios from the game, League of Legends. We found that the presence of gameplay sabotage elicited stronger negative emotions and triggered greater player-reported intentions to retaliate and correct the offending player than in comparable instances of unintentional poor gameplay. Further exploratory analyses suggested that participants rated poor gameplay as less acceptable in more …

Surgeon Health And Well-Being Initiative: A Survey Of General And Orthopedic Surgery Residents' Reports Of Musculoskeletal Pain., Maryam Mohamed, Grace J Kim, Kristen Conrad-Schnetz, Zhan Yang, Mary Carneval

Ambulatory and Primary Care Articles

Background Musculoskeletal (MSK) pain is a well-known risk among surgeons, resulting from the multifactorial physical demands of the occupation. Because of the demands faced by resident surgeons, many individuals find themselves with sometimes debilitating MSK pain. Although these risks are well documented and there have been proposed solutions, there is little discussion on the role that osteopathic manipulative treatment (OMT) can play in relief of MSK pain over time in this population. Objective The purpose of this study is to determine the prevalence and distribution of MSK pain among general and orthopedic surgery residents at Cleveland Clinic Foundation (CCF). Based …

Extinction Risk Of Coral Reef Fishes In The Philippine Marine Ornamental Trade, Jemelyn Grace Baldisimo Sepulveda

Biological Sciences Theses & Dissertations

Coral reef ecosystems in the Philippines face severe threats from intense fishing and habitat degradation. This dissertation evaluated the extinction risk of fishes in the Philippine Marine Aquarium Trade (MAT) using Productivity Susceptibility Analysis (PSA) and temporal genomics. A global PSA framework was modified by including local susceptibility factors. Of the 103 species evaluated, six were categorized as highly vulnerable and 62 as moderately vulnerable, revealing increased local vulnerability and underscoring the importance of local assessments to guide conservation efforts.

Temporal genomics compared historical (1908–1909 U.S.S. Albatross Expedition) and contemporary populations of the MAT-targeted Sphaeramia nematoptera and Pseudanthias squamipinnis, …

Physiological, Cognitive, Behavioral, And Perceptual Contributors To Falls Risk Across Middle And Older Adulthood, Jacquelyn Moxey

Rehabilitation Sciences Theses & Dissertations

Falls are multifactorial events influenced by physiological, cognitive, behavioral, and perceptual factors. Although falls prevention research has traditionally focused on older adults and objectively measured physical impairments, less is known about how cognitive performance, physical activity, and perceptions of ability collectively contribute to falls risk vulnerability across middle and older adulthood. This dissertation examined these relationships through three complementary studies.

Study 1 examined associations between cognitive screening performance and physiological falls risk in 315 community-dwelling older adults. Lower global cognitive performance was associated with greater physiological falls risk. Performance on items reflecting attention and visuospatial/executive function demonstrated the strongest domain-level …

Long-Term Spatiotemporal Change In Coral Reef Fish Populations And Communities In The Philippines, John Christopher Whalen

Biological Sciences Theses & Dissertations

The Visayas Region of the Philippines is a global epicenter of marine fish biodiversity. Hypotheses attribute this peak of species richness within the Coral Triangle to processes that occur at geological time scales. However, changes in biodiversity may occur on ecological time scales, allowing for the assessment of the potential impact of anthropogenic activities. Recent declines in genetic, species, and ecosystem diversity have been observed in the tropics, including the Philippines. Within the Philippines the Visayas Region is considered the epicenter of species adversity due to anthropogenic stressors such as habitat degradation, overfishing, and harvesting individuals for the aquarium trade. …

Virtual laboratories offer a potential solution to the access and scalability challenges of laboratory courses by allowing students to conduct experiments without physical equipment or geographical constraints. AI-powered teaching assistants, particularly those grounded in course-specific materials, can help mitigate the instructional support gap that arises when students work independently in digital learning environments. This dissertation presents three-phase research into …

Quantitative Surface-Enhanced Raman Spectroscopy For Antiretroviral Drug Monitoring: Novel Quality Index And Distributional Approaches In Aqueous And Plasma Matrices, Marguerite Rose Butler

Chemistry & Biochemistry Theses & Dissertations

Surface-enhanced Raman spectroscopy (SERS) offers high sensitivity for molecular detection but is limited for quantitative applications by spatial heterogeneity in signal enhancement on dried colloidal substrates. This Dissertation addresses these limitations through the development and evaluation of novel quantitative methods applied to the antiretroviral drugs tenofovir and emtricitabine.

A quality index (Qi) metric was developed to rank individual SERS spectra within each well based on analyte peak prominence relative to local baseline. SERS spectra were acquired from evaporated silver colloid deposits on aluminum well plates using a custom raster-scanning Raman system. Calibration curves were constructed using the top-ranked spectra (Top-Qi …

I Was There, I Belonged There, And I Should Be There: The Adult Student Experience In Community College Courses Filled With High School Students, Charles Douglas Bowling

Educational Leadership & Workforce Development Theses & Dissertations

The rapid expansion of dual-enrollment and early college high school programs in North Carolina has led to a substantial increase in the numbers of dual-enrolled high school students in community college classrooms. This exploratory case study examined how adult students described their experiences in university-transfer courses in which dual-enrolled high school students make up the majority of the class. It also examined how some of these adult students’ instructors described the experiences of these adult students.

The current study was conducted at three community colleges in rural counties in southern Appalachia and included semi-structured interviews with 18 adult students (24-60 …

Interpretable Sparse Modeling Of Longitudinal Signals Via Critical-Range Rectification And Anytime Rule Compression, Jason Orender

Computer Science Theses & Dissertations

High-dimensional longitudinal data arise in clinical monitoring, industrial control systems, and other sensor-driven domains where outcomes are often governed by threshold-and-lag behavior. Traditional longitudinal workflows frequently depend on expert guessing to nominate candidate variables, lag windows, and threshold hypotheses, followed by repeated hypothesis testing over a limited set of manually specified relationships. While such approaches can be useful in narrow settings, they are often less robust in high-dimensional regimes because important interactions may be missed, multicollinearity can destabilize inference, and the resulting process can be labor-intensive and difficult to scale. This dissertation develops an end-to-end framework for interpretable sparse longitudinal …

Empirical Rhetorical Modeling: New Analytical Tools To Evaluate The Intensity Of Rhetoric, August Immel

English Theses & Dissertations

Since 2020, the United States has experienced a surge of incendiary rhetoric in contemporary political discourse, which exacerbates societal polarization and incites violence as evidenced by heightened politically motivated attacks. Numerous actors characterize the impetus of such violence as “extreme rhetoric.” No standard definition exists for such a term, and this gap necessitates the central research question of this dissertation, which interrogates how rhetoric can be systematically evaluated for “extremeness.” I propose that the issue of extreme rhetoric can be fruitfully examined from within the context of rhetorical theory, but instead of attempting to create a new definition of “extreme …

Faculty Conceptualizations Of Recreational Therapy And Disability: Influences On The Formal, Hidden, And Null Curricula In Undergraduate Recreational Therapy Education, Shelly Lynne Beaver

Human Movement Studies & Special Education Theses & Dissertations

Undergraduate education is a bedrock of professional preparation for entry-level recreational therapists, shaping their scope of practice, philosophical orientations, and approaches to service delivery. While significant attention has been given to the development of a formal recreational therapy curriculum – explicitly taught knowledge, skills, and competencies – little is known about the hidden and null curricula that may implicitly or unintentionally shape students’ professional identities, values, and beliefs. While these less explicit curricular dimensions may have profound effects on how preservice recreational therapists conceptualize both recreational therapy and disability, their impact remains largely unknown. Therefore, the aim of this research …

Experimental Investigation Of The Discharge Modes Of Nanosecond Pulsed Plasmas At Atmospheric Pressure, Md Ziaur Rahman

Electrical & Computer Engineering Theses & Dissertations

The generation of repeatable and stable nanosecond pulsed atmospheric pressure plasmas is important to non-thermal plasma applications in various fields including medicine, material processing, food processing, and plasma ignition for combustion. This dissertation investigates the atmospheric pressure plasma initiation and formation under 10 – 200 ns pulsed power for electrode configurations applicable for transient plasma ignition (TPI) for combustion. The impacts of pulsed power parameters, gas condition, and electrode geometry on the discharge initiation and modes (i.e., streamer, transient spark and spark) are systematically evaluated for applying TPI for combustion. We evaluated the discharge modes driven by both longer and …

De Facto Captivity In The Land Of The Free: Exploring The Confining Effects Of Network And System Avoidance, Brianna Ovalle

Sociology & Criminal Justice Theses & Dissertations

Encroaching state surveillance has primarily targeted people of color living in urban, inner cities, resulting in both much higher likelihoods of encountering state agents and the consequences of such contact. The ceaseless surveillance has led some individuals to engage in protective behaviors aimed at minimizing encounters with agents of the CLS. These behaviors are adaptable to present risks of surveillance and contact with the system. While there are various types of avoidance, the focus of this research is system avoidance and network avoidance. Previous literature for both types of avoidance focuses on the experiences of lower SES men. Further, as …
