Classification Of Land Cover In Sentinel-2 Imagery Using Machine Learning Models, Ehsan Ali Al-Zubaidi, Mohammed Ridha Hammoodi, Ahmed Naser Alzurfi

Al-Bahir

Remote sensing data of medium resolution are commonly used to classify land cover, and machine learning (ML) models have taken on a central aspect in the necessary data analysis. Ordinarily, land cover is coded on a pixel basis on the basis of Digital Number (DN) values, which in turn are computed across several spectral bands. This paper is concerned with land cover mapping in Mosul, Iraq, based on satellite images captured by Sentinel-2. Two platforms featuring unsupervised classification algorithms were used, Google Earth Engine and ArcMap, making it possible to use K-means and X-means in Google Earth Engine and ISO …

Eight helping professionals were randomly selected from the pool of 29 participants representing a convenience sample, with the age range from 20 to 44 years. Data were collected via online in-depth interviews with open-ended questions concerning emotion scheme of their intense experience of compassion satisfaction. To analyze the data, phenomenology and consensual qualitative analysis …

Residential Life As An Equity Strategy For First-Year Persistence Among First-Generation, Low-Income, And Racially Minoritized Students, Joshua Kwaku Addai

Poster Presentations

Despite decades of research on student retention, first-year attrition continues to disproportionately affect first-generation, low-income, and racially minoritized students. Institutional responses have largely emphasized financial aid, advising reform, and classroom-based interventions. However, students spend much of their first year within residential environments; spaces that profoundly shape belonging, identity development, and daily engagement. This study argues that residential life is not merely a housing function but a critical, and often underexamined, site of equity-driven student persistence. Drawing on Tinto’s theory of academic and social integration and Museus’s Culturally Engaging Campus Environments (CECE) model, this literature review synthesizes interdisciplinary research to examine …

Sweep Angle Effects Of Flow Over A Seal Whisker-Inspired Undulated Cylinder, Trevor Dunt, Christin T. Murphy, Ondrej Fercak, Raúl Bayoán Cal, Jennifer A. Franck

Mechanical and Materials Engineering Faculty Publications and Presentations

Flow over a seal whisker-inspired undulated cylinder at swept back angles is computationally investigated, comparing the vortex shedding, forces, and wake characteristics to those of an equivalent smooth geometry. Numerous prior studies have demonstrated that undulated cylinders can reduce mean drag and unsteady lift oscillations; however, none have isolated the effects of the sweep angle resulting from whisker positioning in flow. Inspired by the active control seals exert over their whiskers while navigating and sensing in unsteady aquatic environments, this study investigates how such orientation influences the hydrodynamic performance of the geometry. Simulations are performed of flow across a rigid, …

Weakening Relations Over Duals Of Limit Ordinals, Nikolaos Galatos, Isis A. Gallardo

Mathematics: Faculty Scholarship

We prove that all varieties generated by weakening relation algebras over duals of limit ordinals have a decidable equational theory. We also show that there are only countably-many such varieties and they form a chain that embeds in. The time warp algebra is isomorphic to one of these weakening relation algebras (over the dual of the naturals), so we obtain the main result of a recent publication as a special case. The algebras we study connect to the theory of relation algebras, to time warps and graded modalities, and to the algebraic semantics of substructural logics. Our methods are inspired …

Design, Synthesis, And Bioevaluation Of Moxifloxacin Hydrazide Metal Complexes: Integrated Spectroscopic, Computational, Antimicrobial, And Anticancer Investigations, Abbas Mamdoh Abbas, Sara Reda Fisal, Ibrahim A.I. Ali, W. Christropher Boyd, Haitham F. Kalil, Adel Sayed Orabi

Chemistry Faculty Publications

This study reports the synthesis, spectroscopic characterization, and biological evaluation of a novel moxifloxacin hydrazide derivative (MOX-H) and its metal complexes with Co(II), Ni(II), Cu(II), VO(IV), and Gd(III). The ligand was synthesized by hydrazinolysis of moxifloxacin hydrochloride, and the resulting hydrazide was subsequently complexed with the respective metal salts. The interaction between MOX-H and the metal ions yielded the corresponding complexes, formulated as [Co(H2O)Cl(MOX-H)2]Cl & centerdot;2.5H2O, [Ni(H2O)Cl(MOX-H)2]Cl.4.5H2O, [VO(MOX-H)2]SO4.3.5H2O, [Gd (H2O)(MOX-H)2(NO3)2]NO3.2H2O, and [Cu(MOX-H)2(H2O)Cl]Cl & centerdot;xH2O (where x = 2, 2.5, 0.5, for products synthesized via template, microwave-assisted, and hydrothermal methods, respectively). The synthesized analogues were characterized by elemental analysis (CHN), FT-IR, …

The River Of Life In Flannery O'Connor's "The River", Abbi L. Peo

Undergraduate Honors Theses

This thesis examines the role of the River in “The River” by Flannery O’Connor.  O’Connor’s fiction consistently explores the workings of grace and “The River” is no exception. In the story, the River functions as a metaphor for Christ’s grace. Most literary critics focus on the disconcerting drowning of the young protagonist, Harry Ashfield, an example of O’Connor’s signature use of the grotesque to facilitate her characters’ encounters with grace. However, this emphasis on Harry often obscures the broader role of the River within the narrative. When the story’s analysis is limited to Harry’s death, critics overlook how the River …

(W)Holistic Approaches: Empowering The Whole Of Child, Annette Johnson, Tiarnah Hamlin, Jack Lundie-Jenkins, Erin King, Karen Malyon, Jennifer Cartmel

International Journal of Playwork Practice

Holistic approaches are an evolving pedagogy in the Outside of School Hours Care (OSHC) sector that, despite its recognised value, remain an elusive practice for many educators. This ambiguity has been acknowledged in My Time Our Place (MTOP): Framework for School Age Care in Australia 2.0 (AGDE, 2022). In alignment with this process, the ability for OSHC and extended learning to empower children’s self-identities is fundamental to supporting their holistic development. In a world emerging from the coronavirus pandemic, the ongoing impacts on children – the result of physical separation and societal stressors – cannot be ignored. Accordingly, the child’s …

Who Let The Werewolves Into The Manuscripts: Written And Pictorial Representations Of Werewolves In English Manuscripts, Allison Slowiak

LSU Master's Theses

The werewolf – a fictional figure that transforms from human to wolf – serves as a compelling example of how medieval thought shaped ideas about identity and transformation. The motif of the werewolf, present in a small corpus of works from the tenth through the fourteenth century, emerged to explore the limits of change while also comparing the likeness of humanity to its animal counterpart. This paper explores medieval literature - Beowulf, Bisclavret, Biclarel, and Melion – from both French or English descent to offer overlapping and contrasting thoughts about human likeness to wolves. The manuscripts - The Nowell Codex, …

A Standard Notation System For Beatbox And Vocal Percussion, Andrew W. Bass

LSU Master's Theses

Every instrument in the cannon has a standard notation system. Even percussion, with its hundreds of instruments, has a system of notation that can be understood. With that being said, Beatbox/ vocal percussion does not have a standardized notation for its music. As a beatboxer myself, when I perform, I often have to either create my own part to perform or I have to listen to a recording of a previous performance of a piece. In the rare occasion when there is sheet music, it is often not clear. Pentatonix is currently the premier A Capella group and when I …

Computational Medicine Center Faculty Papers

Guidelines for managing scientific data have been established under the FAIR principles, requiring that data be Findable, Accessible, Interoperable, and Reusable. In many scientific disciplines, especially computational biology, both data and models are key to progress. For this reason, and recognizing that such models are a very special type of "data", we argue that computational models, especially mechanistic models prevalent in medicine, physiology and systems biology, deserve a complementary set of guidelines. We propose the CURE principles, emphasizing that models should be Credible, Understandable, Reproducible, and Extensible. We delve into each principle, discussing verification, validation, and uncertainty quantification for model …

Insights Into Stroke Risk And Prediction For Underweight Individuals, Saeed Awad M. Alqahtani, Moutasem S. Aboonq

Neurosciences

This review explores the relationship between underweight status and stroke risk and outcomes. Although the impact of obesity on stroke is well-documented, the harmful effects of being underweight are often overlooked. Drawing on evidence from observational studies, case-control studies, and meta-analyses, this review highlights that underweight individuals face increased mortality, poorer functional recovery, and higher rates of major adverse cardiovascular events and recurrent strokes post-stroke. Challenges in stroke prediction for this population are examined, including the limited research focus, shortcomings of existing risk assessment tools such as the CHA₂DS₂-VASc score, and population-specific factors affecting underweight prevalence …

A Pretraining-Based Framework For On-Device Training Of Imu-Based Locomotion Mode Detection For Wearable Active Exoskeletons, Muhammad Tahir Khan

LSU Master's Theses

Active exoskeletons are being developed to support human movement in physically demanding industries such as construction. For these systems to work effectively, they must be able to correctly identify the user’s current activity. This process is known as locomotion mode detection and plays an important role in selecting the appropriate control parameters for exoskeletons. Many existing approaches use inertial measurement units (IMUs) to recognize these activities and have shown strong performance. However, most of these methods depend on large amounts of labeled data collected under specific conditions. As a result, they often do not perform well when applied to new …

Influence Of Depressive Symptoms On Disease Activity In Patients With Rheumatoid Arthritis: The Mediating Effect Of Self-Efficacy, Wen-Wei Lin, Chieh-Tsung Yen, Hua-Lung Huang, Hanoch Livneh, Ming-Chi Lu, Wei-Jen Chen, Tzung-Yi Tsai

Leadership, Learning and Counseling Faculty Publications and Presentations

Background and Objectives:

Rheumatoid arthritis (RA) is a lifelong autoimmune disease in which joint inflammation is caused by a dysfunctional immune system. Synchronous depressive symptoms have been identified as determinants of disease progression, especially disease activity as measured using the 28-joint Disease Activity Score (DAS28). Although growing evidence suggests the interplay between depression and DAS28 in RA, related findings remain inconsistent, implying that a pivotal underlying mechanism is overlooked. Hence, we aimed to examine whether self-efficacy, the belief in one’s ability to manage health, could mediate the association between depressive symptoms and DAS28.

Materials and Methods:

Between January and October …
