From the figure of load, material index is formulated as a reference for performance property requirements. Using data from analysis software and qualitative data, eight performance criteria such as durability, corrosion resistance, cost, and environmental impact are then weighted using the …

Metallurgical Investigation Of A Modified Eye Bolt Failure Caused By Improper Weld Extension, Specification Deviation, And Crevice Corrosion, Dimas Muhammad Fawwaz, Reza Miftahul Ulum, Johny Wahyuadi Soedarsono, Yudha Pratesa

Journal of Materials Exploration and Findings

A modified eye bolt from the David Arm Manhole Storage Tank underwent thorough metallurgical study due to the consequences of the bolt's malfunction during operation. Safety issues arose when the manhole door detached during operation. The mechanical testing and chemical composition analysis of the bolts indicated they were manufactured from an ASTM A193 Grade B7 material used for high-temperature bolting. This material did not conform to the engineering drawing, which mentioned SA 563A, which is about nuts, not bolts. This contradiction clearly shows that the eye bolt which was installed does not conform to the intended design. Welded connections of …

Non-Native English-Speaking Teachers Of Writing, Native-Speaker Ideologies, And Feedback Uptake In First-Year Composition, Mustapha Bannerman

Rhetoric and Composition PhD papers

Research on non-native English-speaking teachers (NNESTs) and writing feedback has rarely examined how students’ perceptions of multilingual instructors shape feedback uptake. This critical literature review synthesizes scholarship from composition studies, second language writing, translingualism, and NNEST research to examine this relationship in first-year composition. The review argues that native-speaker ideologies may shape perceptions of instructor credibility in ways that could influence students’ willingness to trust and apply feedback during revision. It identifies a significant gap in existing scholarship and calls for empirical research and pedagogical practices that promote linguistic justice, multilingualism, and equitable writing instruction in higher education.

Locating-Chromatic Number Of Bipartite Graphs, Dian Kastika Syofyan, Edy Tri Baskoro, Hilda Assiyatun, Ira Apni Purwasih, Zata Yumni Awanis, Arga Febriantoni

Baghdad Science Journal

The locating-chromatic number of a graph combines proper vertex coloring with vertex identification through distances to color classes. Although this parameter has been studied for many graph families, general results for bipartite graphs remain limited. Bipartite graphs contain structural symmetries, especially within each partite set, making it difficult to obtain distinct color codes. This paper establishes lower and upper bounds for the locating-chromatic number of bipartite graphs using neighborhood equivalence classes in the two partite sets. The bounds describe the effect of identical neighborhoods on the number of distinguishable color codes. They are shown to be tight, and regular complete …

Dynamical Properties Of Proximal Group Spaces, Najlaa Adnan Hadi

Baghdad Science Journal

In this paper, we introduce a new class of dynamical systems, Proximal Dispersive Group Spaces (PDG - spaces), to study the structure of topological group actions. In these spaces, we observe a mixture of two different behaviors: points come close to each other (proximal convergence) under some group elements, while remaining separated (dispersive separation) under others. This framework generalizes the classical theory to allow for selective convergence without global asymptotic collapse. We give a formal definition of PDG - spaces and study some of their basic properties, like invariance under group actions and incompatibility with equicontinuous systems. Our results show …

Their properties were characterized using X-ray diffraction (XRD), vibrating sample magnetometry (VSM), and field-emission scanning electron microscopy (FE-SEM). XRD confirmed a single-phase cubic spinel structure for all compositions. A gradual peak shift with increasing La³⁺ content indicated lattice expansion, attributable to the larger ionic radius …

Synergistic Photodetectors Based On Sno2/Si With Cnts Via Vacuum Thermal Evaporation, Sozan A. Hassan, Walla M. Mohammd, Mohanad Q. Kareem, Kawkab D. Salim

Baghdad Science Journal

This study presents a precision-engineered carbon nanotube (CNT)-doped SnO₂/Si heterojunction photodetector, wherein interfacial physics governs performance beyond individual material capabilities. Stepwise CNT loadings (0, 0.03, and 0.07 wt.%) were deposited by vacuum thermal evaporation to systematically reconstruct the crystallographic, morphological and band-alignment landscape. A-sure X-ray diffraction demonstrates that the rutile phase remains, and atomic force microscopy and scanning electron microscopy confirm grain passivation at the nanoscale. High sub-bandgap light sensitivity can be achieved, benefiting from the built-in field-assisted carrier separation at the SnO₂/Si interface, whereby the redshifted absorption edge is indicative of intentional bandgap engineering. CNT …

Predicting Cesarean Section Delivery In The United States Using Machine Learning: Population-Based Retrospective Study, Yanchao Yang

Business Analytics Faculty Publications

Background:
Cesarean section (C-section) is the most common surgical procedure in the United States, yet its use varies widely across regions and institutions. Although clinical risk factors are central to delivery decisions, geographic context, health system capacity, and local practice patterns may also influence C-section use. Understanding both the determinants and predictability of C-section delivery is important for improving obstetric quality and equity.

Objective:
This study aims to document geographic variation in C-section use across the United States, identify maternal and county-level factors associated with C-section delivery, and evaluate the predictive performance of machine learning models across clinically defined risk …

Determining The Feasibility Of A Habituation Assessment In Managed Red Wolves, Emily C. Lynch, Joseph W. Hinton, Jennifer B. Nagashima, Curtis Malott, Natalie J. Johnson, Emily Haering, Robin Petersen, Allison Johnson, Julie K. Young

Wildland Resources Faculty Publications

For species extirpated from the wild, ex situ breeding programs are essential for providing the individuals necessary for re-establishing wild populations through reintroductions. However, repeated exposure to humans under managed care may reduce wariness and alter behavioral responses in ways that are maladaptive after release. Although some pre-release behaviors reflect natural responses essential for survival and reproduction, others may result from habituation to humans and increase the risk of conflict, recapture, or mortality following translocation. These risks underscore the need for behavioral assessments to help identify appropriate candidates for release. However, because the assessments themselves require some exposure to humans, …

Physical Design Automation For Next Generation Ics: Graph And Machine Learning Based Approaches, Dr. Kritanta Saha

Doctoral Theses

Integrated Circuit (IC) technology has progressed significantly over the last six decades, culminating in billions of transistors on a chip. The widely used 193 nm immersion lithography process exceeds modern feature sizes, leading to layout pattern distortions and electrical violations. Mitigation techniques such as Multiple Patterning and Optical Proximity Correction become ineffective below 45 nm, prompting the development of several Next-Generation Lithography (NGL) methods such as Extreme Ultraviolet Lithography (EUVL), Multiple Electron Beam Lithography (MEBL). MEBL employs thousands to millions of e-beams in parallel to overcome throughput limitations. A 2D layout is partitioned into vertical stripes by stitch-lines (SLs), each …
