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 …

Trustworthy Artificial Intelligence For Real-Time Quality Assurance In Additive Manufacturing, Md Shafikul Islam

LSU Master's Theses

Additive manufacturing requires quality assurance methods capable of detecting process anomalies before defects propagate across subsequent layers. This thesis develops a trustworthy artificial intelligence framework for real-time surface anomaly detection in Fused Deposition Modeling (FDM) using laser-derived depth maps and Vision Transformers (ViTs). Conventional convolutional models aggregate global context gradually through stacked local kernels, which can limit their sensitivity to spatially distributed surface deviations. The proposed approach instead tokenizes depth-map patches and applies global self-attention to classify four process conditions: normal printing, under-extrusion, over-extrusion, and empty or void regions. The framework combines token-level attention visualization, vanilla saliency, Integrated Gradients, and …

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 …

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 …

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 …

Research outputs 2022 to 2026

Gastric cancer remains a major global health burden, ranking fifth worldwide in both incidence and mortality. While Helicobacter pylori is a well-established Group I carcinogen, increasing evidence suggests that non-H. pylori bacteria, including Streptococcus anginosus, may also contribute to gastric carcinogenesis. However, their comparative pathogenic roles and interactions remain poorly defined. In this study, public databases showed stage-dependent abundance changes of H. pylori and S. anginosus but no significant correlation during gastric cancer progression. We further quantified both bacteria in gastric fluid samples collected from 500 individuals using a non-invasive gastric string test and in fecal samples from an independent …
