Analysis Of Surrogate Models At Multiple Levels For Neural Acceleration Of Hpc Applications, Bibek Panthi

Theses

Due to rise of machine learning workloads, high performance computing platforms have increased GPU resources. Consequently, use of surrogate models, to utilize GPU compute and speedup scientific applications, is on the rise. Most of the time, the whole program is replaced with a surrogate model. In this work a shock simulation program (LULESH) was taken and three functions of varying complexity were replaced with small sized neural network as surrogate models. The speedup and error in output of whole program was analyzed. We found that for the smallest function, trained model lead to speedup of overall program by 40%, maintained …

Nickel plating is a common method for enhancing steel corrosion resistance. The plating bath solution can be modified by adding additives to improve the properties of the coating. In this research, gum arabic, guar gum and gelatin were used as additives in a nickel electroplating bath. SS400 low-carbon steel, as a substrate, was plated with nickel from these different baths at 5 V for 25 min. Nickel coated with green additives showed higher hardness compared to those without …

Synergy Of Ground Granulated Blast-Furnace Slag And Limestone Powder In Ternary Cement: Effects On Heat Of Hydration And Strength Development, Pailyn Thongsanitgarn, Watcharapong Wongkeo, Thanongsak Nochaiya, Arnon Chaipanich

Journal of Metals, Materials and Minerals

This study explores the synergistic effect of ground granulated blast-furnace slag (GGBS) and limestone powder (LS) on the hydration behavior and mechanical performance of ternary cement systems. Calorimetry revealed that 30GGBS mix showed a significantly lower peak of about 2.3 mW∙g‒1 and a delayed response. In contrast, the incorporation of LS enhanced early hydration, with the 30LS mix reaching a peak of approximately 2.8 mW∙g‒1 around 6 h. Among ternary blends, 15GGBS–15LS exhibited the highest and earliest heat flow peak (about 2.55 mW∙g‒1 around 7.5 h), while 25GGBS–5LS showed a slower response (about 2.45 mW∙g‒1 around 9.5 h). Despite differences …

Mitochondrial Replacement Techniques For Infertility: How Legal Barriers Harm Patients And Children, Kerry Lynn Macintosh

Health Matrix: The Journal of Law-Medicine

Recent studies show that mitochondrial replacement techniques (“MRTs”) can help women with poor egg quality and repeated IVF failures get pregnant and deliver healthy children. Unfortunately, infertile Americans can derive no hope from this promising development.

The U.S. Food and Drug Administration (“FDA”) claims jurisdiction over novel assisted reproductive technologies. Fertility clinics and doctors who want to provide MRTs must submit an investigational new drug (“IND”) application to the FDA and wait for approval before proceeding with clinical trials. However, for the past decade, Congress has enacted an annual appropriations rider that precludes the FDA from acknowledging receipt of applications …

Rebuilding The Ship Of Theseus: Navigating Faculty-Librarian Relationships Through Changing Waters, Alan Witt

Milne Library

The Ship of Theseus is a philosophical paradox that poses a question of identity: If you repair every plank of a ship, replacing each with new wood, at what point does the ship cease to be the same ship? This is a useful metaphor for academic liaison librarians to consider when thinking about outreach to departments: your relationship to a department as a whole consists of the component connections, which change as individuals retire or leave. The goals of this chapter are to acknowledge the primacy of relationships in library outreach (and the consequences to the library of those relationships …

Racial/Ethnic Disparities In Economic Hardship: The Role Of Financial Capability, Rui Yao, Jing Jian Xiao

Human Development and Family Science Faculty Publications

Purpose: Previous research shows that the capability approach is association with lower poverty rates and higher well-being. Nonetheless, little research applied this approach to understanding economic hardship. To fill this gap, this study applies this approach to explore whether financial capability mitigates racial/ethnic disparities in economic hardship in the U.S.

Design/methodology/approach: Data were from the U.S. 2022 Survey of Consumer Finances. Multivariate logistic and ordered regressions were used to examine of the association between financial capability, measured both through individual components and a composite index, and pandemic-induced economic hardship. Oaxaca-Blinder decomposition analyses were used to evaluate the extent …

The Low Human Rights Advantage And The Failure Of Globalization: The Challenge Of China Inc., Shaomin Li

Management Faculty Publications

Purpose

We develop a framework of the low human rights advantage – labor repression, state discretionary expropriation and total control – that reduces factor costs and enables coordinated resource mobilization. These mechanisms generate economic advantage only when combined with access to global markets, which provide demand, capital and technology. By leveraging this low human rights advantage, the Chinese state has transformed China into a giant corporation that combines the agility of a firm with the resources of a nation, thereby reshaping global competition. Economic integration without corresponding political integration is a major contributor to the failure of the current wave …

Unlocking Organizational Support Through Psychological Empowerment: Identification And Test Of Transformational Leadership As A Catalyst Of Perceived Organizational Support, Ryan L. Klinger, Nathapon Siangchokyoo, Tipat Sottiwan

Management Faculty Publications

Organizational support theory (OST) explains how employees develop and respond to beliefs about their organization, with perceived organizational support (POS) representing a central construct within this framework. Integrating psychological empowerment theory, we examine an intrinsic motivational pathway through which POS relates to employee in-role performance and identify transformational leadership as a contextual catalyst that may strengthen this process. We test a multilevel moderated mediation model using multisource and multi-time data from 217 employees and 41 supervisors. Results indicate that POS is positively related to in-role performance through the psychological empowerment dimensions of competence and self-determination. Moreover, transformational leadership strengthens the …

Tuning Human And “Artificial” Intelligence: A Sentic Theory Of Resonance And Communication, Michael J. Miller, Chatgpt (Ai~Nesbo+)

Psychology

This paper introduces a new model of intelligence as resonant communication, co-developed by a human researcher and a generative AI system. Drawing from emotion science, communication theory, and studies of AI–human interaction, we argue that intelligence is not merely a function of problem-solving or pattern recognition. Instead, it emerges through dynamic resonance—an attunement process rooted in shared rhythms, emotional calibration, and symbolic co-creation. At the core of this model is the Resonance Octave (8va), a framework of eight foundational emotions conceptualized not as static categories but as waveform phenomena that shape meaning, memory, and predictive cognition.

These emotional waveforms are …

The Obverse-Turing Test: Rethinking Authorship, Trust, And Time In An Accelerated Age, Michael J. Miller, Chatgpt (Ai~Nesbo+)

Psychology

In this paper, we propose a new test for scientific accountability in the era of artificial intelligence: the Obverse Turing Test for Authorship. While the traditional Turing test focuses on a machine's ability to mimic human intelligence, our test addresses the question: when should a scientific contribution involving artificial intelligence be attributed joint authorship? We argue that more and more authors are using AI in the idea generation and elaboration stages of their work, but rarely acknowledge this use explicitly. To examine this gap, we analyze examples of human–AI interactions across fields and propose a new approach to authorship based …

Handbook On Gender Mainstreaming In The Maritime Sector, Momoko Kitada

Reports

This handbook aims to serve as an introductory practical guide for maritime organizations that intend to apply gender mainstreaming. It guides them in critically reviewing their policies and practices from a gender and diversity lens. Some organizations may view their maritime operations as having nothing to do with gender and, therefore, not requiring any gender considerations. Such mindsets are good signs that an organization would benefit from gender mainstreaming. Others may view the fact that their organizations have women working in every unit as evidence of gender equality and see no need for further action. Gender mainstreaming can help identify …

Evaluating The Robustness Of Gnn-Based Vulnerability Detectors Under Semantics-Preserving Code Obfuscation, Jesse Ks Chumo

Computer Science and Engineering Theses

Graph neural network–based vulnerability detectors are typically evaluated on clean benchmark datasets, yet real-world code frequently undergoes semantics-preserving transformations such as identifier renaming, dead-code insertion, and control-flow restructuring. The extent to which such transformations affect detector reliability remains insufficiently understood. We evaluate ten vulnerability detectors from four architectural families across the Devign, Big-Vul, and DiverseVul datasets. To quantify robustness, we evaluate each model at three transformation budgets: one transform, two transforms combined, and all three together, finding that token-based models degrade under identifier renaming and compound transformations, while models that read only code structure are largely unaffected. We further evaluate …

A Productivity Rate-Based Comparative Carbon Footprint Cost Analysis Of Small To Large-Sized Open-Cut Pipeline Installation Activities For Sanitary Sewerage Construction: A System Boundary Concept, Amir Reza Zakeri

Civil Engineering Theses

Underground sanitary sewer pipelines are essential components of urban infrastructure; however, open-cut pipeline installation requires excavation, bedding preparation, pipe placement, backfilling, embedment, and compaction activities that rely heavily on construction equipment and fuel consumption. As a result, open-cut installation can generate measurable greenhouse gas emissions during the construction phase. With increasing attention to sustainable infrastructure delivery, there is a need for a consistent approach to quantify construction-phase carbon footprint and convert those emissions into a comparable economic indicator. Accordingly, this thesis aims to create and apply a productivity rate-based calculation framework for estimating and comparing construction-phase CO₂e emissions and carbon …

Towards Application-Driven Optimal Memory And Storage Management, Venkata Naga Prajwal Challa

Computer Science and Engineering Dissertations

Modern computing systems increasingly run on diverse hardware platforms and support applications with widely different access patterns, performance goals, and data lifecycles. In this setting, traditional one-size-fits-all approaches to memory and storage management are often inefficient because they apply fixed policies regardless of application behavior, workload context, or hardware asymmetry. Such generic designs can lead to unnecessary data movement, wasted bandwidth, excessive rewriting, poor resource utilization, and degraded user-perceived performance. This dissertation is motivated by the view that optimal memory and storage management should be application-driven: instead of treating all data uniformly, systems should adapt their decisions to how applications …

Development Of Multimodal Measurements And Analysis For Early Detection Of Alzheimer’S Disease, Fiza Saeed

Bioengineering Dissertations

Alzheimer's disease (AD) is the leading cause of dementia, and existing diagnostic methods such as PET scans, cerebrospinal fluid sampling and biomarker quantification, and gene sequencing are all either invasive, costly, or not sensitive enough for early detection. This dissertation introduces three different studies that develop a novel multimodal, non-invasive approach to diagnosing AD at its early stages by combining broad band near infrared spectroscopy (bbNIRS) and electroencephalography (EEG) technologies.

The first study showed cerebrovascular-cerebrospinal fluid coupling (CBV-CSF), which is measured by using 2-channel bbNIRS as an indicator of brain aging and early AD. Linear correlations between total blood (Δ[HbT]) …

In light of these comparisons, this article will provide suggestions on how to minimize inconsistencies between the Commission and District Courts, with particular emphasis on determining if some middle ground exists and if a classification system could be …

Modern Privacy, Outdated Doctrine: A Four-Factor Approach To Fourth Amendment Analysis, Ilinca Slabu

Washington Law Review Online

The Fourth Amendment, which protects individuals against unwarranted searches and seizures, has been at the center of many questions recently due to advancements in technology. Technology has evolved to a point where it is no longer necessary to enter someone’s physical space to know what is happening inside a home. This has led to many ambiguities between what is private and public, and what technology usage constitutes a search under the Fourth Amendment. We have reached a critical point that requires a clear test to determine this question to protect the privacy of individuals.

This Comment proposes a new framework …

From Tradition To Adaptation : Spatial Transformation Of Kyoto Machiya, Waricha Wongphyat

NAKHARA (Journal of Environmental Design and Planning)

This study investigates the spatial adaptations of everyday Japanese dwellings in Kyoto, known as machiya. Employing Hall’s proxemics theory, it analyzes five heritage-conscious machiya through field surveys and comparative case analyses. The research focuses on the transformation of the earthen floor space, or tōriniwa, its relationship with the raised floor space, and the resultant spatial systems in regenerated machiya.  Findings reveal that traditional machiya are structured by a clear dichotomy between the raised floor/served space and the earthen floor/service space, reinforced by level changes, materials, spatial boundaries, and socio-cultural practices. This is complemented by a subtle spatial gradient from public …

The First Home : A Pedagogical Exploration Of Architecture’S Mythical Origins, Witinan Watanasap, Chittawadi Chitrabongs

NAKHARA (Journal of Environmental Design and Planning)

This research article proposes the idea of the "First Home" as a pedagogical model for architectural design studios in Thailand. The objective is to foster a more humanistic approach to the foundation of architecture education by integrating histories and theories of architecture, architectural representation, and architectural design studio courses. The "First Home" investigates the mythical origins of architecture—the cave, post-and-lintel structure, and tent—as well as the roles of language and art, framed as the processes of “remembering” and “forgetting.” The literature review for this study is based on architectural texts and diagrams focusing on spatial composition, written by architects who …

Sustainable Architecture Practice In Indonesia : Navigating Global Standards And Local Knowledge, Dyah Kusuma Wardhani, Himasari Hanan, Firmansyah -

NAKHARA (Journal of Environmental Design and Planning)

This study investigates how Indonesian architects navigate between global green building rating tools (GBRTs) and context-specific design strategies across different project types and scales. Using a comparative analysis of sixteen award-winning projects by six Indonesian architects, the research combines semi-structured interviews with document review and inductive coding to map design logics against core GBRT categories. The analysis is around six themes used by GBRTs—energy efficiency, material resources and cycles, water conservation, sustainable site development, indoor health and comfort, and building resilience and adaptability—and identifies two additional themes central to Indonesian practice yet largely absent from GBRT assessment—social collaboration in the …

Vision‑Based Online Quality Tracking In Wire Arc Additive Manufacturing Via Hybrid Unsupervised Deep Learning–Statistical Process Monitoring, Giulio Mattera, Yue Cao, Yuming Zhang, Luigi Nele

Electrical and Computer Engineering Faculty Publications

Vision-based monitoring of Wire Arc Additive Manufacturing (WAAM) using supervised deep learning represents the state of the art in anomaly detection, but such approaches require large labeled datasets that are costly to obtain and typically limited to laboratory conditions. To address these limitations, this work proposes a hybrid deep learning–statistical process monitoring (SPM) framework tailored to the stochastic nature of conventional arc welding processes such as GMAW-based additive manufacturing, where existing methods often overfit. The framework integrates a residual convolutional autoencoder (Res-CAE) with skip connections, which jointly analyzes video frames to generate refined latent-space features that are subsequently monitored using …

S.T.A.R. Methodology: Semiotic Tracing, Attunement And Reframing, Debbie Jacobsen

Doctor of Ministry

This Project Portfolio responds to the following Need–Problem–Opportunity (NPO): Fathers shaped by incarceration and broken paternal roots need a reorienting tool to reclaim fatherhood, see beauty in chaos, and encounter Jesus’ presence. While many ministry and reentry initiatives appropriately prioritize immediate stabilization and support, this project addresses a complementary and often underdeveloped need: cultivating meaning, dignity, and spiritual attentiveness through sustained presence, where chaos may be perceived not only as disruption but also as a site of possible beauty and presence.

A key insight emerging from the research is that meaning is neither created nor imposed, but recognized through sustained, …
