Understanding Visual Representation Of Imputed Data For Aiding Human Decision-Making, Ryan M. Thompson

Browse all Theses and Dissertations

The effectiveness of representing higher dimensional data on a two-dimensional visualization was required to be studied in the development of a novel data imputation method, Continuous Imputation With Association Rules (CIWAR). When the CIWAR method is used to impute missing data, the method generates additional metadata that increases each imputed data point's dimensionality. Potential use cases for CIWAR include situations where imputed data would be analyzed by individuals with little or no data analytic experience or situations where imputed data would be used to aid high-stress time-critical human decision processes. A study was conducted to assess the effect of the …

Exploring The Relationship Between Teamwork Skills And Team Members' Centrality, Francisco Cima, Pilar Pazos, Ana Maria Canto

Engineering Management & Systems Engineering Faculty Publications

The present paper describes an exploratory study of small teams working on a four-month project as part of a graduate engineering program. The research had two primary goals. The first was to utilize the log files from shared repositories used for team collaboration to describe the network structure of the teams. The second was to determine whether the network centrality of any individual team member is associated with their teamwork skills and attitudes towards the collaboration platform. The relationship between teamwork skills, attitudes towards the collaboration technology, and the centrality index was explored using Pearson correlations. A total of 35 …

Regulation Of Δnp63Α By Tip60 Promotes Cellular Proliferation, Andrew Jared Stacy

Browse all Theses and Dissertations

ΔNp63α is a p53 transcription factor family member that promotes cellular proliferation and survival. In squamous cell carcinoma (SCC), ΔNp63α overexpression is associated with poor prognosis and survival, implicating it as a proto-oncogene. Despite its importance in SCC, the mechanisms regulating ΔNp63α expression are poorly understood. We have identified the acetyltransferase TIP60 as a novel upstream regulator of ΔNp63α levels. We discovered that TIP60 regulates ΔNp63α via two mechanisms. First, TIP60 upregulates ΔNp63α mRNA levels. Moreover, pharmacological inhibition of TIP60 activity reduces ΔNp63α transcript levels, indicating that TIP60-cataltyic activity is vital to amplified transcription of ΔNp63α. Second, we have demonstrated …

Host-Parasite Interactions: Comparative Analyses Of Population Genomics, Disease-Associated Genomic Regions, And Host Use, Sara Rose Seibert

Browse all Theses and Dissertations

Birds are major vectors and reservoir hosts of pathogens across our globe. Pathogens can be spread through the dispersal and seasonal movements of migratory and resident wild birds. Although biogeographic barriers have the potential to restrict completely or in part gene flow in wild birds, variation in ecological drivers of dispersal likely influences the effectiveness of these barriers amongst different species. This dissertation seeks to enhance our knowledge of Southern Hemisphere waterfowl species’ dispersal, population genomics, and disease ecology using population genomic techniques (double-digest restriction-site associated DNA sequencing (ddRADseq)) and multi-variate statistics. First, we investigated the roles of dispersal behavior …

Scalable, Pluggable, And Fault Tolerant Multi-Modal Situational Awareness Data Stream Management Systems, Michael Partin

Browse all Theses and Dissertations

Features and attributes that describe an event (disasters, social movements, etc.) are heterogeneous in nature. For virtually all events that impact humans, technology enables us to capture a large amount and variety of data from many sources, including humans (i.e., social media) and sensors/internet of things (IoTs). The corresponding modalities of data include text, imagery, voice and video, along with structured data such as gazetteers (i.e., location-based data) and government and statistical data. However, even though there is often an abundance of information produced, this information is fragmented across the various modalities and sources. The DisasterRecord system aims to provide …

Browse all Theses and Dissertations

Deep Neural Networks (DNNs) are powerful tools blossomed in a variety of successful real-life applications. While the performance of DNNs is outstanding, their opaque nature raises a growing concern in the community, causing suspicions on the reliability and trustworthiness of decisions made by DNNs. In order to release such concerns and towards building reliable deep learning systems, research efforts are actively made in diverse aspects such as model interpretation, model fairness and bias, adversarial attacks and defenses, and so on. In this dissertation, we focus on the research topic of DNN interpretations for visual intelligence, aiming to unfold the black-box …

Gold/Qds-Embedded-Ceria Nanoparticles: Optical Fluorescence Enhancement As A Quenching Sensor, Nader Shehata, Effat Samir, Ishac Kandas

Electrical & Computer Engineering Faculty Publications

This work focuses on improving the fluorescence intensity of cerium oxide (ceria) nanoparticles (NPs) through added plasmonic nanostructures. Ceria nanoparticles are fluorescent nanostructures which can emit visible fluorescence emissions under violet excitation. Here, we investigated different added plasmonic nanostructures, such as gold nanoparticles (Au NPs) and Cadmium sulfide/selenide quantum dots (CdS/CdSe QDs), to check the enhancement of fluorescence intensity emissions caused by ceria NPs. Different plasmonic resonances of both aforementioned nanostructures have been selected to develop optical coupling with both fluorescence excitation and emission wavelengths of ceria. In addition, different additions whether in-situ or post-synthesis have been investigated. We found …

A Narrative Approach To Understanding Career Attrition For Women Engineers, Brian Merritt Scott

Inclusion & Marginalization: How Perceptions Of Design Thinking Pedagogy Influence Computer, Electrical, And Software Engineering Identity, Sarah L. Rodriguez, Erin E. Doran, Rachel E. Friedensen, Elizabeth Martínez-Podolsky, Paul S. Hengesteg

Faculty Publications

Engineering identity plays a vital role in the persistence of engineering students, yet limited research exists on how particular pedagogical approaches influence engineering identity at the college level. This qualitative case study explored how undergraduate student perceptions of design thinking pedagogy influence computer, electrical, and software engineering identity. The study found that design thinking pedagogy reinforces the recognition of an engineering identity, particularly for those from historically marginalized groups (i.e., women, people of color). Intentional implementation, including organization and framing of design thinking pedagogy, was an essential foundation for fostering student interest in the course and connecting to their role …

Set And Spike: Mentoring A Student-Athlete In Stem For Undergraduate Engineering Education Research, Leroy Long Iii, Mckenna D. Gooch

Publications

It is well known that student-athletes are more diverse and higher academic achievers, on average, than their collegiate peers. However, little research has explored the mentoring relationships of student-athletes who conduct undergraduate research. Unique challenges and opportunities exist for student-athletes and faculty when it comes to mentoring undergraduate research in fields like science, technology, engineering and math (STEM). Using a collaborative autoethnographic methodological approach and apprenticeship theory, our personal narratives detail how an engineering professor mentored a former engineering student-athlete for undergraduate engineering education research. We offer several findings and recommendations.

Vortex Fluidic Mediated Synthesis Of Polysulfone, Aghil Igder, Scott Pye, Ahmed Hussein Mohammed Al-Antaki, Alireza Keshavarz, Colin L. Raston, Ata Nosrati

Research outputs 2014 to 2021

Polysulfone (PSF) was prepared under high shear in a vortex fluidic device (VFD) operating in confined mode, and its properties compared with that prepared using batch processing. This involved reacting the pre-prepared disodium salt of bisphenol A (BPA) with a 4,4′-dihalodiphenylsulfone under anhydrous conditions. Scanning electron microscopy (SEM) established that in the thin film microfluidic platform, the PSF particles are sheet-like, for short reaction times, and fibrous for long reaction times, in contrast to spherical like particles for the polymer prepared using the conventional batch synthesis. The operating parameters of the VFD (rotational speed of the glass tube, its tilt …

ENGR 333

Today, many institutions and individuals see energy efficiency as an important issue; reducing energy consumption is thought to decrease demand for fossil fuels and consumes energy more sustainably. However, while more efficient devices can save users both energy and money, they do not always result in less energy use as a society. This discrepancy between expected and actual energy savings is called the rebound effect. This can be a result of several factors: increased use of the device drawing more energy, manufacturers using more energy to create the new device, or money saved by the users being respent in the …

Energy efficiency can be a worthy goal for institutions and individuals; reducing energy consumption decreases demand for fossil fuels and consumes energy more sustainably. However, more cost-effective devices can lead to behavioral changes that ultimately increase energy consumption, even though the devices themselves are more energy efficient: This called the rebound effect. Rebound occurs when less energy is saved than expected. This can be a result of several factors: increased use of the device drawing more energy, manufacturers using more energy to create the new device, or money saved by the users being re-spent in the economy.

Expression Systems For Synthetic Spider Silk Protein Production, Michaela R. Hugie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spider silk is a biodegradable and biocompatible natural material that is stronger than steel and more elastic than nylon. These properties make spider silk a desirable material for many commercial products, ranging from textiles to biomedical materials. Due to spiders’ cannibalistic and territorial nature it is impossible to farm them to produce spider silk at a high enough yield to meet product demands. Therefore, a bioengineered synthetic process is necessary to produce spider silk. Synthetic spider silk has been produced in bacteria, goats, yeast, plants, mammalian cells and silkworms, but none of these processes provided a commercially viable yield or …

Career Prospects And Resources Of Domestic Engineering Doctoral Students, Laura A. Gelles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Career prospects are a motivating factor for entry and retention of doctoral students, especially in the discipline of engineering. While doctoral student training provides them with highly specialized skills to be an independent researcher, they may not have the requisite skills or guidance to secure the job position of their choice. Therefore, it is important to provide doctoral students with opportunities, training, and information (i.e., resources) about different types of careers to not only ensure they are productive contributors of teaching and research, but also equip them for future career prospects. Research techniques based upon in-depth narrative interviews and combining …

Human Rights, Environmental Justice, Social Justice, Faith Values And Ethics: Building Stronger Partnerships For The Common Good By Understanding The Differences, Theresa Harris, Leanne M. Jablonski, Sarah Fortner, Malcolm Daniels

Biennial Conference: The Social Practice of Human Rights

Partnerships between human rights practitioners, local communities, scientists, engineers, and health professionals have shown potential to address deeply rooted, systemic human rights concerns. These collaborations are essential for achieving the UN Sustainable Development Goals (SDGs), and for engaging the perspectives and expertise of all constituents. However, even when the individuals in these partnerships or the organizations they represent have common goals, their motivations, analyses, and solutions often come from different perspectives. Members of good will can inadvertently alienate one another when attempting to work together. The fields of human rights, social justice, environmental justice, and ethics have each developed their …

Adipose Tissue Engineering: A Therapeutic Strategy For The Treatment Of Obesity And Glucose Intolerance, Michael A. Hendley

Theses and Dissertations

Despite available treatment options, the number of people afflicted by type 2 diabetes has steadily risen for decades. Nearly 90% of the diabetic population also suffers from obesity and the link between the two diseases is undeniable. Characterized by rapid expansion of the adipose tissue and improper lipid storage, the mishandling of lipids by adipose tissue promotes the diabetic state. Excess lipids, unable to be properly stored, build up in peripheral tissues promoting insulin resistance and type 2 diabetes. Therapeutic strategies designed to address adipose tissue lipid handling could represent a promising treatment strategy for obesity associated type 2 diabetes. …

Sandy Soil Improvement Through Microbially Induced Calcite Precipitation (Micp) By Immersion, Shihui Liu, Kang Du, Wei Huang, Lin Li

Civil and Architectural Engineering Faculty Research

The goal of this article is to develop an immersion method to improve the microbially induced calcite precipitation (MICP) treated samples. A batch reactor was assembled to immerse soil samples into cementation media. The cementation media can freely diffuse into the soil samples in the batch reactor instead of cementation media being injected. A full contact flexible mold, a rigid full contact mold, and a cored brick mold were used to prepare different soil sample holders. Synthetic fibers and natural fibers were selected to reinforce the MICP-treated soil samples. The precipitated CaCO3 in different areas of the MICP-treated samples was …
