Optimizing Artificial Neural Networks For Smart Grid Stability Analysis Using Tabu Search-Based Hyperparameter Tuning, Salwa Khalid Abdulateef, Armaneesa Naaman Hasoon, Moceheb Lazam Shuwandy Nov 2025

Optimizing Artificial Neural Networks For Smart Grid Stability Analysis Using Tabu Search-Based Hyperparameter Tuning, Salwa Khalid Abdulateef, Armaneesa Naaman Hasoon, Moceheb Lazam Shuwandy

Baghdad Science Journal

Smart grids are supposed to make electricity networks more reliable, yet in practice their behavior can be surprisingly unstable when the load changes too quickly. During this work, we tried to understand that instability and to build a model that predicts when a grid remains stable or begins to drift. We used an Artificial Neural Network and tuned it with a Tabu Search routine that keeps adjusting the number of neurons and the activation functions until the results stop improving. It was not a single run; several training attempts were needed before the model settled. After applying the Tabu optimization, …

Thinning Antarctic Glaciers Expose High-Altitude Nunataks Delivering More Bioavailable Iron To The Southern Ocean, Kate Winter, John Woodward, Stuart A. Dunning, James R. Jordan, Joseph A. Graly, Matthew J. Westoby, Sian F. Henley, Robert Raiswell

School of Geography, Earth and Environmental Sciences

Glacial systems entrain and transfer sediment, rich in essential nutrients, from continental sources to the ocean, where they are released by meltwater. In the Southern Ocean, primary producers are limited by the availability of micronutrients, like iron (Fe), so any increase in continental sediment supply could enhance primary productivity and subsequent drawdown of atmospheric CO2. Here we provide a systematic account of labile Fe concentrations in Antarctic continental sediments. Ferrihydrite and crystalline Fe (oxyhydr)oxides were extracted from 27 Antarctic samples collected from nunataks, lateral moraines and blue ice areas in the Sør Rondane Mountains, East Antarctica. We report …

Node-Attributed Spatial Graph Partitioning: A Kullback-Leibler Divergence Based Approach, Valentin Nechita Nov 2025

Node-Attributed Spatial Graph Partitioning: A Kullback-Leibler Divergence Based Approach, Valentin Nechita

Electronic Theses and Dissertations

This thesis presents a novel approach to node-attributed spatial graph partitioning (NSGP) that addresses limitations in existing homogeneity measures. We introduce a Kullback-Leibler (KL) divergence-based formulation we name KLD that measures attribute similarity by comparing each node’s distribution to its subgraph centroid, providing a computationally efficient method of measuring homogeneity. Integrated within a multilevel graph partitioning framework and Fiduccia-Mattheyses refinement, our approach achieves approximately 90% runtime reduction compared to the baseline Clustering and Local Refinement (CLR) algorithm while maintaining comparable partition quality. Applied to COVID-19 infection data combined with American Community Survey demographics across U.S. FIPS codes, KLD successfully identifies …

Cultural Synthesis In Iranian Graphic Design: A Fusion Of Tradition And Modernity, Maryam Mehrabadi Nov 2025

Cultural Synthesis In Iranian Graphic Design: A Fusion Of Tradition And Modernity, Maryam Mehrabadi

LSU Doctoral Dissertations

This thesis examines Iranian graphic design as a politically embedded and semiotically charged field wherein visual form operates as a site of ideological negotiation, cultural memory, and symbolic resistance. Focusing on the works of Ghobad Shiva and Morteza Momayez, the study situates graphic design within the sociopolitical constraints of the Pahlavi monarchy and the post-1979 Islamic Republic. It argues that Iranian design practices cannot be understood outside the country’s enduring identity crisis—shaped by the unresolved tension between three coexisting cultural strata: ancient Persian heritage, Islamic civilizational identity, and Western modernity. Drawing on the work of Edward Said, the thesis also …

School of Geography, Earth and Environmental Sciences

Calcium carbonate precipitation in ageing ocean crust sequesters carbon dioxide dissolved in seawater through seafloor weathering reactions, influencing atmospheric CO2 concentrations on million-year timescales. However, this crustal carbon sink, and the extent it balances CO2 degassing during crustal formation at mid-ocean ridges, remain poorly quantified due to limited sampling of the vast ridge flanks where CO2 uptake continues for millions of years. Here we quantify the carbon sink hosted within talus breccias that accumulated through mass wasting 61 million years ago during rift faulting at the slow spreading Mid-Atlantic Ridge, cored during International Ocean Discovery Program South Atlantic Transect Expedition …

Bladder prolapse, also known as cystocoele, is the most common form of pelvic organ prolapse (POP), significantly affecting women's physical, sexual, and psychosocial health, particularly in low- and middle-income countries (LMICs). Despite its widespread prevalence and disabling consequences, bladder prolapse remains under-recognised and inadequately addressed in global health strategies. Prevalence estimates vary widely across regions, from 3%-64.6%, influenced by diagnostic methods and cultural reporting biases. Common risk factors include high parity, early childbirth, prolonged labour, poor postpartum care, malnutrition, obesity, and ageing. Clinical diagnosis often relies on simplified grading systems in resource-limited settings. Conservative treatments like pelvic floor muscle training …

Low-Energy Multiphoton Scattering At Tree-Level And One-Loop Order In A Homogeneous Electromagnetic Field, James Edwards, Ivan Ahumada Hernandez, Patrick Copinger Nov 2025

Low-Energy Multiphoton Scattering At Tree-Level And One-Loop Order In A Homogeneous Electromagnetic Field, James Edwards, Ivan Ahumada Hernandez, Patrick Copinger

School of Engineering, Computing and Mathematics

We study low energy photons coupled to scalar and spinor matter in the presence of an arbitrary homogeneous electromagnetic field in a first-quantized (worldline) approach. Utilizing a Fock-Schwinger gauge for both the scattering photons and homogeneous background, simple compact expressions are found for both the photon- and background-dressed effective action and propagator in scalar and spinor quantum electrodynamics. The low-energy limit allows identification of the coupling of the scattering photons as one of an effective homogeneous superposition of their field strengths, with amplitudes following from application of a suitable linearization operator. To treat the linearization, several techniques are employed, including …

Between Sovereignty And Commons: Legal Frameworks For Digital Data Governance In India, Anushka Sachan Nov 2025

Between Sovereignty And Commons: Legal Frameworks For Digital Data Governance In India, Anushka Sachan

Journal of Law and Public Policy

This legislative note critically examines the Indian Digital Personal Data Protection (DPDP) Act, 2023, with a focus on its provisions that imply data sovereignty and their implications for the governance of digital commons. Drawing on the seminal works on data commons, the note explores the conceptual and practical tensions between centralised data sovereignty, participatory, and decentralised models of data stewardship. While data sovereignty is often justified on grounds of national security and control, it may inadvertently hinder the development of inclusive and accountable frameworks for managing data as a public good.

Revisiting The Meaning Of 'Forests'—In Re: T.N. Godavarman Thirumulpad V Uoi, Gayathri D. Naik

Journal of Law and Public Policy

This Case Comment reflects on the contributions of the judiciary to forest governance and management through the use of continuous mandamus in the landmark case T.N. Godavarman v UoI. It offers insights into these contributions, particularly an expansion of the understanding of ‘forests’, by examining the latest judicial decision in the Godavarman series, which was on the protection of sacred groves in Rajasthan. The expansion of the definition of ‘forests’ to include sacred groves can help accord the protection and ensure the preservation of these small forest lands with rich biodiversity and religious and cultural significance.
