A Framework To Audit Scheduling Events In The Linux Operating System, Edward G. Hudgins

Open Access Theses & Dissertations

Soft real-time systems have responsiveness requirements that are desirable but not critical for operational effectiveness. This Thesis describes a new scheduler logging framework named "Integrated Process Scheduler Archiver" (IPSA) intended to assist with this analysis. Due to human sensitivity to interface delays on gesture-driven devices, mobile devices are a common case of soft-real time systems. Mobile systems generally do not incorporate real-time schedulers, but instead utilize over-provisioning and a variety of scheduling heuristics to generally provide acceptable responsiveness. These devices are highly multi-programmed Energy limitations on mobile limit the extent of overprovisioning, thereby increasing the sensitivity of system behavior to …

Comparison Of Mesoscopic Fracture Analysis Techniques: A Case Study Near Onion Creek Diapir, Paradox Basin, Utah, Muhammed Tarik Iraz

Open Access Theses & Dissertations

Faults and fractures are abundant along the diapir contact in the Onion Creek Diapir in eastern Utah and relate to the mechanisms of diapir formation. Western Onion Creek exhumes two spectacular exposures of the diapir contact and adjacent wall rocks providing two nearly orthogonal transects oriented ~E-W and S-N. In this study, I used field measurements from natural outcrops and a 3D model developed using Structure-from-Motion/Multiview Stereo photogrammetry to evaluate fracture reservoir development along diapir margins. The 3D-Model was developed using Agisoft Photoscan from ~3200 ground-based images and was georeferenced using 76 ground control points located with a GPS unit …

Onshore-Offshore Velocity Models North Of The Mendocino Triple Junction In Northern California, Alan Jacquez

Open Access Theses & Dissertations

The Mendocino Triple Junction (MTJ) marks the boundary where the Gorda plate, North American Plate, and Pacific Plate meet, separating the Cascadia subduction zone to the North from transform tectonics of the San Andreas plate boundary. This actively deforming region experiences high seismic activity and young geological features. Here we examine offshore and onshore seismic wide-angle reflection and refraction data north of the MTJ crossing the Cascadia subduction zone from offshore northern California to the Western edge of the Sierra Nevada. We image subsurface structures in this region by creating P-wave velocity models using datasets collected in 1993 to 1994 …

Environmental Injustice And Racial/Ethnic Heterogeneity In Houston, Texas, Michel G. Loustaunau Garcia

Open Access Theses & Dissertations

This Thesis seeks to contribute to distributive environmental justice (EJ) research by analyzing racial/ethnic and intra-ethnic disparities in potential health risks from exposure to hazardous air pollutants (HAPs) in Harris County, the most populous county in Texas. Previous EJ research in this urban area has not examined intra-ethnic heterogeneity in exposure to air pollutants or attempted to compare social disparities in exposure to air pollution caused by vehicular (mobile) and point (stationary) sources. The goal of this study is to determine how the EJ implications of cancer risks from inhalation exposure to HAPs from mobile and stationary sources differ across …

Titanium Incorporated Gallium Oxide (Ga-Ti-O): Structure Property Relationship And Performance Evaluation For Extreme Environment Applications, Sandeep Manandhar

Open Access Theses & Dissertations

The existing power generation systems, which utilize fossil fuels, are in dire need of efficient, reliable chemical sensors that can operate safely at higher temperatures. These sensors control the combustion environment and the emissions during combustion. Several sensing materials such as SnO2, ZnO, TiO2, WO3, and Ga2O3 exhibit high sensitivity to certain type of chemical molecules and in a certain range of temperatures. Among these candidate materials, β-Ga2O3 is stable at very high temperatures and has shown functionality for oxygen sensing at higher temperatures (>700°C). However, the response time and sensitivity must be significantly improved in order to derive …

Evaluation Of Recycled Gypsum Application Dosages To Enhance The Water Infiltration Rate At Water Retention Ponds, Jorge Luis Navarrete

Open Access Theses & Dissertations

The retention ponds play central role for efficient collection, removal, and drainage of rainfall runoff from surrounding streets to minimize flooding and damage. However, low percolating retention ponds may result in an extended ponding of water, abundance bacteria accumulations, mosquito breeding, environmental hazards, among others. The presence of clayey soils and soil sodicity reduces infiltration rates of retention ponds. To enhance the infiltration rate of ponds, it is proposed to use recycled gypsum (RG), as a soil amendment in retention ponds consisting of clayey soils to enhance low infiltration rates.

To evaluate the influence of RG in clayey soils as …

Evaluation Of Brackish Water Desalination By Membrane Capacitive Deionization Systems: Performance Tradeoffs In Salt Removal, Hydraulic Recovery, Charge Efficiency, And Specific Energy Consumption, Oluwaseye Michael Owoseni

Open Access Theses & Dissertations

As potable water demand continues to exceed availability in several regions of the world, alternative water sources such as desalination and direct potable reuse have become of high importance in water sustainability discussions. The conventional desalination technologies include reverse osmosis (RO) and thermal distillation. Major barriers to the applicability of these technologies for desalination include inorganic scaling (RO) and high energy requirements respectively. This research provides an evaluation for the feasibility of Membrane Capacitive Deionization (MCDI), which is a technology gaining interest due to its theoretically low energy requirements for brackish water (less than 3 g/L) desalination. The motivation for …

A Combined Field, Experimental And Modeling Approach To Understand The Impacts Of Flood Irrigation On Pedogenic Caco3 And Co2 Dynamics In Drylands, Anna Cristina Ortiz

Open Access Theses & Dissertations

Soil salinization is a global problem affecting 10% of agricultural soils, particularly in irrigated arid-lands. This study investigated salt loading through flood-irrigation, particularly of calcite (CaCO3) salt in the southwest of the United States. To evaluate the impact that flood-irrigation has on CaCO3 buildup and its effect on C-cycling, a natural soil and two agricultural soils were sampled: a pecan orchard and an alfalfa field in the El Paso, TX region. Agricultural soils in this study are flood irrigated by the Rio Grande river and by ground waters in its absence, both of which are oversaturated with calcite.

To trace …

No Habrá Rey Sin Reina: Gender Discourse In Isabel, A Contemporary Representation Of Queen Isabel I Of Castile And King Fernando Ii Of Aragon, Michelle Sabrina Peters

Open Access Theses & Dissertations

By examining the figures of the Catholic Monarchs -Isabel and Fernando- in the popular television show Isabel, this research demonstrates how the historical fiction genre tends to privilege the stories of exceptional women and the men surrounding them. Unlike other historical fiction shows where the emphasis is placed on the empowerment of a single female character, Isabel emphasizes the mutual empowerment and equitable dynamic between a woman and a man. In an era when gender roles and prejudice were particularly strict, Fernando and Isabel enter into marriage with diametrically opposed notions of gender roles. However, when they begin ruling and …

A Psychometric Evaluation Of The Treatment Self-Regulation Questionnaire (Tsrq) For Assessing Motivations For Responsible Drinking, Dylan Keith Richards

Open Access Theses & Dissertations

Self-determination theory (SDT) may be useful for understanding alcohol use and alcohol-related consequences among college students. A version of the Treatment Self-Regulation Questionnaire (TSRQ; Ryan & Connell, 1989) exists for assessing motivations proposed by SDT for responsible drinking, but no study has evaluated its psychometric properties. Thus, the purpose of the present studies was to provide a psychometric evaluation of this version of the TSRQ. In Study 1, among a convenience sample of college student drinkers (n = 308), a four-factor structure of the TSRQ that is theoretically consistent with SDT was supported; however, the amotivation subscale demonstrated unacceptable internal …

Data-Driven Predictive Framework For Modeling Complex Multi-Physics Engineering Applications, Arturo Schiaffino Bustamante

Open Access Theses & Dissertations

Computational models are often encountered in multiple engineering application, such as structural design, material science, heat transfer and fluid dynamics. These simulations offer the engineers the capability of understanding complex physical situations before putting them to practice, either through experimentation or prototyping. The current advances in computational sciences, hardware architecture, software development and big data technology, have allowed the construction of sturdy predicting frameworks for analyzing a wide array of natural phenomena across different disciplines, either through the implementation of statistical methods, such as big data, and uncertainty quantification, or through high performance computing of a numerical model. The objective …

"Wommanly Noblesse:" Female Gender Dynamics In Medieval Romance, Mary Elizabeth Shaner

Open Access Theses & Dissertations

Exploring systemic, gendered power dynamics and inequalities for women within medieval Matters of Rome, France, and Britain Romances is essential to understanding real-world sociopolitical power structures and female gender roles. Diverging from most previous scholarship in my use of critics as well as in my interpretation of Criseyde and Guinevere as protagonists, my argument examines how scholars would laud the heroic bravery of Geoffrey Chaucer's Criseyde and Sir Thomas Malory's Guinevere if they were male heroes, yet because of the narrative conventions of medieval Romance, Courtly Love, Chivalry, and the Antifeminist Traditions, these fictive women are seen as the destroyers …

We Got This: Toward A Facilitator-Youth Apprenticeship Approach Supporting Collaboration And Design Challenges In Youth-Designed Mobile Location-Based Games, Sara Vogel, Judy Perry

Publications and Research

It's May at a New York City high school’s after-school program. We—the adult facilitators—have been guiding a group of youth to produce a location-based mobile game. The teens have worked dozens of hours and want to see a finished product. But with the final playtest coming soon, we are stuck. Reflecting on the most recent session with the participants, we realize that the game is far behind where it should be. Despite having already begun to code the game and write its interactive text, the game’s core mechanics are still only half-baked, and adjusting problematic real-world locations in the digital …

Burnout Syndrome And Depression, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

In this chapter, we proposed an overview of burnout, from the introduction of the construct in the mid-1970s to the growing realization that the syndrome was better conceived of as a depressive condition. Recent studies have shown that the distinction between burnout and depression is problematic, both theoretically and empirically. The history of burnout research suggests that transdisciplinary communication and methodological standards should be strengthened to avoid the proliferation of constructs that, in fact, refer to the same phenomena. Construct proliferation, a transgression of the scientific canon of parsimony, is considered a major problem today because it undermines theory building …

Interpretation Bias Toward Ambiguous Information In Burnout And Depression, Renzo Bianchi, Eric Laurent, Irvin Sam Schonfeld, Jay Verkuilen, Chantal Berna

Publications and Research

Burnout has been defined as a job-related syndrome combining pervasive fatigue and loss of motivation. In recent years, evidence has mounted that burnout may reflect a depressive condition. In this study, we expanded on past investigations of burnout-depression overlap by focusing on interpretation biases toward ambiguous information among the two entities. We conducted a web-based study involving 1056 participants (83% female; mean age: 42.87). Burnout symptoms were assessed with the Shirom-Melamed Burnout Measure and depressive symptoms with the PHQ-9. The Ambiguous Scenarios Test (AST), a measure of interpretation bias validated among dysphoric individuals, was the outcome of interest. The AST …
