Physics-Informed Heterogeneous Spatiotemporal Graph Neural Network For Reservoir Simulation, Ahmed A.M.A. Abdullah

LSU Master's Theses

Reservoir simulation is the state-of-the-art method for predicting the flow of petroleum reservoir fluids in porous media. It provides an accurate and unbiased prediction of the performance of petroleum reservoirs under different operating conditions. Despite its advantages, reservoir simulation is computationally expensive; with typical full-field simulation models running for several hours. This limitation is worsened when simulating reservoirs with several equations for each cell, such as multiphysics or compositional reservoir simulation. The goal of this research is to provide a fast and accurate spatiotemporal machine-learning model that incorporates discretized governing mass balance equations for training. To achieve this, we propose …

Investigating The Role Of The I-Ii Linker In Nav1.5, Emily Wagner

McKelvey School of Engineering Graduate Student Theses & Dissertations

The cardiac voltage-gated sodium channel, Nav1.5 is essential for initiating the cardiac action potential. Its dysfunction can lead to dangerous arrhythmias, sudden cardiac arrest, and death. Like many channels, its known properties depend heavily on its structure. The functional core of the alpha subunit consists of four homologous repeats (I, II, III, and IV), each formed from a voltage sensing domain and a pore domain. The channel also contains two cytoplasmic termini and three cytoplasmic linkers (I-II, II-III, and III-IV). While most of the channel has been resolved in multiple structures, the I-II and II-III linkers have remained conspicuously absent …

School of Earth, Environmental, & Marine Sciences Faculty Publications

In an environment increasingly dominated by roads, wildlife crossing structures (WCS) have been installed to decrease wildlife mortality and improve habitat linkages. In South Texas, vehicle collisions have been a major mortality source for the endangered ocelot ( Leopardus pardalis ). To mitigate threats to this species, eight WCS, along with associated fencing, were strategically placed along Farm‐to‐Market Road 106 (FM106), which passes through ocelot habitat. We assessed the rate of on‐roadway crossings and WCS use by GPS‐collared animals before, during, and after WCS installation using camera traps to verify WCS use. Because of the rarity of ocelots in this …

Clocking In And Speaking Out: Navigating Workday Rhythms For Voice Behaviors, Katelyn M. Reeves

LSU Master's Theses

Employee voice behaviors help organizations identify problems, increase productivity, and enhance satisfaction. Most literature focuses on daily-level variations while neglecting potential within-day variations that may have a stronger impact on voice engagement. To investigate within-day variations, this thesis applies chronotype synchrony to explain resource depletion throughout the day, which will determine voice engagement. An experience sampling study with the day reconstruction method of 250 employees revealed that having a morning chronotype leads to a more promotive and prohibitive voice in the morning, with a decline throughout the day due to resource depletion increasing throughout the day. Further, individuals with evening …

In this paper, we describe the hopes, considerations, and questions of a narrative practice research collaboration among three closely connected transgender (trans) and/or non-binary collaborators, in a collection of work meant to support trans, non-binary, and gender expansive life and in response to trans death at a time of increasing hostility toward trans communities. We apply a specific focus on inquiring into how to do narrative therapy and community work research in and about our own communities, and what the ethical, relational and methodological practices for this work might be. We do this through reflecting on existing literature related to …

Resisting Ableism In Research Design, Gipsy Hosking

The Qualitative Report

This paper explores how ableist assumptions can unintentionally create barriers to participation in research by those of non-normative bodies or minds. In traditional epistemology, bodies are considered “universal” rather than “specific,” and the universal body is coded as fully able-bodied and independent with brain and body adhering to normative standards of the White heterosexual English-speaking male. In this article, I present a story of “enabling participation” for those of diverse body capacity in my work with young women living with chronic illness.^[1]Specifically, I explore the accommodations and adaptions I made to my research design to account for the …

“But The Trauma Did Not Fade Away” Childhood Sexual Abuse, Adolescent Pregnancy, And Rurality, Cynthia H. Mcniss

Electronic Theses and Dissertations

Childhood sexual abuse (CSA) and adolescent pregnancy are critical public health issues that intersect in complex ways, particularly in rural areas. Adolescents who have experienced CSA are at a significantly higher risk of becoming pregnant before the age of 19 compared to their peers without such a history (Madigan et al., 2014). Rurality is also associated with elevated rates of adolescent pregnancy due to various socio-economic and healthcare access challenges ("Rural Health Information Hub," 2024). This study employed a grounded theory approach to develop a comprehensive understanding of the social and psychosocial processes influencing the choices, actions, and decisions of …

Compulsory Heterosexuality And Regulatory Hegemony In English Textbooks, Angelika Mae N. Balingasa

Journal of English and Applied Linguistics

Gender representations are crucial in textbooks given that these instructional materials are integral and widely-acknowledged in the field of education. However, despite various efforts to circumvent gender inequalities, textbooks still remain as conduits for proliferating gender biases and heteronormativity. In this study, secondary English textbooks were examined and sequential explanatory research design was used to investigate how genders were demonstrated in the textbooks through the lens of gender performativity theory. The findings revealed that the textbooks adhered to historical gender conventions, as opposed to genders’ fluid and contingent nature. Additionally, all of the textbooks promote hegemonic masculinity with men dominating …

Solving Edges Deletion Problem Of Complete Graphs, Anwar N. Jasim, Alaa A. Najim

Baghdad Science Journal

As the network size increases, there is an increased probability that some components will fail. It is therefore necessary for the network to be able to maintain the interconnection even in the presence of faulty components. The likelihood of a failure in the connections between stations is higher than that of a failure in the stations themselves because of the nature of many networks. Numerous graph-theoretic methods can be used to examine the reliability and efficacy of a network, and the network's dependability is determined by its connectivity. For a parallel and distributed system, the maximum connection time between any …
