Assessing Computer Vision Based Conflict Detection In Uas Traffic Monitoring Under Secure Communication Constraints, Fadjimata Issoufou Anaroua

Doctoral Dissertations and Master's Theses

The rapid growth of Unmanned Aircraft Systems (UAS) and Advanced Air Mobility (AAM) is creating a new low-altitude airspace ecosystem where drones, air taxis, service suppliers, communication networks, sensors, and ground-based monitoring systems must work together safely. Within this ecosystem, UAS Traffic Management (UTM) is expected to provide a digital framework for coordinating operations beyond traditional air traffic control. However, reliable integration also requires resilient monitoring methods that can detect non-cooperative aircraft, protect communication links, and maintain timely situational awareness under real-world constraints.

This dissertation examines how computer vision can support cooperative monitoring systems such as Remote ID and ADS-B …

Teaching Through Sound: Approaches To The Use Of Fixed Media In Pedagogical Viola Etudes, Roberto C. Mochetti Jr.

LSU Doctoral Dissertations

This dissertation examines the pedagogical possibilities of fixed media in newly composed viola etudes. While fixed media is commonly treated as accompaniment or as a performance medium, this project argues that it can also serve as an active component of technical and musical training. By providing stable and repeatable sonic environments, fixed media can support forms of listening, intonation, sound production, and performer awareness that are difficult to cultivate through traditional etudes alone. This argument responds to a broader pedagogical gap in string training, where long-established etudes and models of technical development remain central even as contemporary viola performance increasingly …

Incorporating Increased Road User Costs Into Pavement Management Modeling: A Case Study Of Two-Lane Rural Highways, Khaled A. Abaza, Mohamed S. Yamany

Faculty Publications

The impact of increased road user costs on optimal pavement rehabilitation plans has been investigated using a simplified pavement management model. The increased road user costs include elevated vehicle operating costs (VOCs) due to work-zone lane closures and traveling on severely deteriorated pavements. A model is proposed for estimating the VOC for work-zone lane closures on two-lane rural highways, considering both stopping and idling costs. Another model for approximating the increased VOC associated with driving on poor/bad pavements is suggested as a function of the relevant VOC rate and a proportionality factor. Sample results are presented for a two-lane rural …

Human-Driven, Autonomous, Or Hybrid? The Optimal Fleet Configurations For Ride-Hailing Platforms, Wenjing Li, Yali Zhang, Jun Sun, Zhaojun Yang

Information Systems Faculty Publications

The growing commercialization of autonomous vehicles (AVs) is reshaping consumer service preferences and prompting ride-hailing platforms to redesign fleet structures that accommodate the coexistence of human-driven vehicles (HVs) and AVs. This article develops a queueing game framework that incorporates vehicle heterogeneity and consumer preference differences to systematically compare three fleet configuration strategies: the pure HV (PHV) strategy (HVs only), the pure AV (PAV) strategy (AVs only), and the hybrid strategy (both HVs and AVs). The analysis highlights how consumer mismatch losses, AV operating costs, and service rates jointly shape equilibrium outcomes. Results show that when consumer mismatch losses are moderate, …

Advances In The Application Of Electroencephalography In Food Sensory Science, Li Wenbin, Hou Xiaoyi, Deng Na, Leng Tuo, Fu Haohua, Wang Jianhui

Food and Machinery

Traditional sensory evaluation of food is affected by subjectivity and other factors, resulting in significant limitations. Electroencephalography (EEG), owing to its advantages of high temporal resolution, non-invasiveness, and real-time dynamic monitoring, offers an objective neurophysiological perspective and analytical approach to address this issue, effectively advancing food science research from subjective descriptions to objective neural decoding. This paper systematically reviews the applications of EEG in food flavor recognition and prediction, objective evaluation of food quality, and analysis of food nutrition and consumer behavior. In light of the current state of technological development, it is proposed that multimodal technology integration and machine …

Law Enforcement Help-Seeking Behaviors And Organizational Mental Health Supports, Jordan Elizabeth Longendorf

Walden Dissertations and Doctoral Studies

Due to the traumatic and repetitive nature of law enforcement work, mental health support is often needed by officers, but is not consistently sought. Law enforcement leaders need to understand this concern as a leading indicator of workforce well-being, organizational effectiveness, and officers’ willingness to seek needed mental health support. Guided by the conceptual framework of Rickwood and Thomas’s help-seeking behaviors, the purpose of this descriptive phenomenological study was to explore law enforcement officers’ lived experiences of help-seeking behaviors for emotional and mental health issues. Data were collected through six semistructured interviews with current law enforcement officers in four different …

Starling, Noriyuki Suzuki, Penny Vlahos, Roland Weber, Bryan W. Brooks

Graduate School of Oceanography Faculty Publications

Knowledge on chemicals, waste, and pollution is shaped by geographical, financial, and disciplinary biases, which can cause blind spots for key emerging issues, including those relevant to low income countries and vulnerable communities. Scientists, practitioners, affected communities, and policy makers working in the areas of the newly established Intergovernmental Science-Policy Panel on Chemicals, Waste, and Pollution (ISP-CWP) have interest in identifying issues of potential and emerging relevance that currently escape their attention. Horizon scanning offers a critical tool to identify such issues. Here, we provide guidance on aligning horizon scanning approaches with differing objectives, audiences, and thematic scopes. We structure …

All Decisions

In this nonpayment proceeding, the court declined to strike the tenant's reply papers after the landlord moved to dismiss the petition on only one day's notice. Exercising its discretion under CPLR 2214(b) and CPLR 406, the court allowed the reply papers, finding that limiting litigants to half-arguments would not serve the goal of a just, speedy, and inexpensive determination of proceedings under CPLR 104.

From Research To Decision In A Uk Parliamentary Office: How Internal Communication Translates Complex Information Into Workplace Action, Donovan Singh

Faculty Curated Undergraduate Works

This project examines how internal workplace communication translates complex information into guidance that a decision-maker can use. The project uses an anonymised UK parliamentary office as a practice-based case study. The elected representative is referred to as MP A, the placement office as Parliamentary Office A, and the placement supervisor as Supervisor B. Anonymisation is necessary because the project analyses briefing practice and workplace feedback rather than the identity, political position, or internal operations of a specific office.

The research question is: How does internal communication translate complex information into clear, accurate and actionable guidance for workplace decision-makers? The project …

Capturing An Electron In The Virtual State, Alok Nath Singh, Bibek Bhandari, Rafael Sánchez, Andrew N. Jordan

Mathematics, Physics, and Computer Science Faculty Articles and Research

We address a foundational question in quantum mechanics: can a particle be directly found in a classically-forbidden virtual state? We instantiate this conceptual question by investigating the traversal of electrons through a tunnel barrier, which we define in a triple quantum dot system where the occupation of the central dot is energetically avoided. The motivation behind this setup is to answer whether the central dot is occupied or not during a virtual transition when it is being explicitly monitored. We investigate this problem in two different limits of continuous measurements: the stochastic quantum diffusion and the quantum jump. We find …

Biological Sciences: Faculty Publications

Climate change is reshaping coastal ecosystems through gradual warming and increasingly frequent extreme heat events, potentially affecting native and introduced species differently. We experimentally compared the native marine snail Littorina obtusata, a habitat and dietary specialist, to the introduced generalist Littorina littorea under sustained warming and short-term extreme heat. We measured survival and performance metrics, including grazing, growth, and attachment strength, under short- and long-term thermal stress in air and water. L. littorea consistently outperformed L. obtusata, maintaining or increasing function under warming and exhibiting greater survival during simulated heatwaves. Conversely, L. obtusata showed performance declines and higher …

Regularization-Based Crystallite Size Distribution Analysis Of Pt/C Catalysts From X-Ray Diffraction, Chenglong Ma, Weiyu Shi, Zhongjun Hou

Online First

Accurate determination of the platinum (Pt) crystallite size distribution in carbon-supported Pt/C catalysts is critical for evaluating both the initial performance and long-term durability of proton exchange membrane fuel cells (PEMFCs). Conventional characterization approaches—including transmission electron microscopy (TEM), small-angle X-ray scattering (SAXS), and the Scherrer equation—are limited by restricted statistical sampling, sensitivity to support interference, or the inability to resolve the full breadth of the size distribution. In this work, we present a regularization-based inversion framework that extracts the volume-weighted crystallite size distribution directly from X-ray diffraction (XRD) line profiles, without requiring any a priori assumption regarding the functional form …

Firms In The Flood: Is Fema Failing Small Businesses?, Lauryn Charles

Electronic Theses and Dissertations 2020 - Present

When faced with a natural disaster, small businesses remain largely outside the direct reach of federal assistance. The Federal Emergency Management Agency (FEMA) estimates that up to 65% of small businesses close within two years of direct impact by a hazard event. Despite this vulnerability, existing research has focused primarily on infrastructure and household recovery, leaving the small business sector underexamined. This study is the first to link county-level IRS income data, FEMA mitigation grants, and SBA disaster records to empirically evaluate whether federal pre-disaster mitigation spending and community social resilience moderate the relationship between disasters and small business recovery …

Trust And Signaling: An Exploratory Study Of Residential Attitudes Towards Energy Efficiency Advisors And Outdoor Media, Hal T. Nelson, Ivana Osmanovic

Public Administration Faculty Publications and Presentations

As the building sector shifts toward community-led energy efficiency (EE) initiatives to mitigate the climate crisis, scaling adoption requires understanding behavioral drivers. This study examines key drivers of EE measure adoption: perceived non-energy benefits, trusted advisors, and behavioral signaling. This research contributes to the energy policy and social science literature by empirically linking social trust with signaling preferences. It extends existing EE adoption decision theories by identifying distinct clusters of “expert” versus “close” advisors across demographic groups. Data from an experimental survey (n = 238) in Portland, Oregon, were analyzed using principal component analysis (PCA) and multivariate regression modeling. Results …

Quantum Geometry Effects In The Very Early Universe And Black Hole Spacetimes, Meysam Motaharfar

LSU Doctoral Dissertations

Loop quantum gravity (LQG) techniques applied to symmetry-reduced spacetimes generically resolve the big bang and black hole interior singularities of classical general relativity. In loop quantum cosmology (LQC), the big bang singularity is replaced with a non-singular quantum bounce connecting the pre-bounce contracting and post-bounce expanding branches, while the black hole interior singularity is, in general, replaced with a smooth finite transition surface yielding a black-hole-to-white-hole transition. In this dissertation, we investigate the implications of quantum gravitational singularity resolution for the physics of the very early universe and black holes within the LQG/LQC framework. In the first part, we show …

Scraping The Earth: Testing Ndvi As An Indicator Of Military Ground Maneuver Within The Israeli Invasion Of The Gaza Strip, Thomas A. Bergeron

LSU Master's Theses

The advancement of open-source (OSINT) and geospatial intelligence (GEOINT) has allowed independent researchers to study human conflict in new ways, with tools that were previously reserved only for state intelligence agencies. In order to advance methodologies, researchers must continue to evaluate new tools to study war.  Valued for its accessibility and moderate spatial resolution, the Normalized Difference Vegetation Index (NDVI) is one such tool that has not been widely systematically tested for its use in an open-source GEOINT investigation of modern conflict. This study tests NDVI as an indicator of military maneuver by leveraging a mixed-method approach against open-source kinetic …
