A Probabilistic Perspective Of Human-Machine Interaction, Mustafa Canan, Mustafa Demir, Samuel Kovacic

Engineering Management & Systems Engineering Faculty Publications

Human-machine interaction (HMI) has become an essential part of the daily routine in organizations. Although the machines are designed with state-of-the-art Artificial Intelligence applications, they are limited in their ability to mimic human behavior. The human-human interaction occurs between two or more humans; when a machine replaces a human, the interaction dynamics are not the same. The results indicate that a machine that interacts with a human can increase the mental uncertainty that a human experiences. Developments in decision sciences indicate that using quantum probability theory (QPT) improves the understanding of human decision-making than merely using classical probability theory (CPT). …

Reciprocal Regulation Of Transketolase-Like 1 And Hypoxia-Inducible Factor 1 Alpha In Metabolic Reprogramming And Growth Of Diffuse Midline Glioma, H3 K27m-Mutant, Christopher Andrew Waker

Browse all Theses and Dissertations

Diffuse midline glioma, K27M-mutant (DMG) are intractable brain tumors, primarily occurring in the pediatric and adolescent population. Patients have a median survival of less than one year after diagnosis. A lack of therapeutic targets has been a barrier to improvement in patient survival. Irradiation therapy improves symptoms while chemotherapy and surgical intervention, for the most part, have not yet demonstrated utility for treatment. DMG are characterized by a histone H3 mutation that results in the genome-wide loss of epigenetic-repressive marks on K27 and is associated with the misexpression of genes, like Cancer/Testis antigens. A member of this group, transketolase-like 1 …

A Design Thinking Framework For Human-Centric Explainable Artificial Intelligence In Time-Critical Systems, Paul Benjamin Stone

Browse all Theses and Dissertations

Artificial Intelligence (AI) has seen a surge in popularity as increased computing power has made it more viable and useful. The increasing complexity of AI, however, leads to can lead to difficulty in understanding or interpreting the results of AI procedures, which can then lead to incorrect predictions, classifications, or analysis of outcomes. The result of these problems can be over-reliance on AI, under-reliance on AI, or simply confusion as to what the results mean. Additionally, the complexity of AI models can obscure the algorithmic, data and design biases to which all models are subject, which may exacerbate negative outcomes, …

Effect Of Build Geometry And Build Parameters On Microstructure, Fatigue Life, And Tensile Properties Of Additively Manufactured Alloy 718, Anna Dunn

Browse all Theses and Dissertations

Additive Manufacturing (AM), particularly laser powder bed fusion, is being studied for use in critical component applications. Tensile and fatigue testing shows differences when built using different laser powers. However, when fabricated in an as-printed geometry, the gauge sections of the two specimens are different and experience different thermal behavior. This work explores microhardness, microstructure size, Niobium segregation, and porosity from samples made with varying laser power and different build geometry sizes representative of the gauge sections in the tensile and fatigue bars. Results show that microhardness varies spatially across the sample. Smaller diameter metallographic coupons (fatigue diameter) have a …

The Role Of Son In Chromatin-Mediated Gene Expression, Melissa Jordan Ward

Browse all Theses and Dissertations

Gene expression in mammalian cells requires complex nuclear choreography, and there is increasing evidence that spatiotemporal organization of chromatin and nuclear compartments plays an important role in gene expression. In this dissertation, I examined the function of SON, a splicing factor with a known role in nuclear organization, in chromatin-mediated gene expression. SON association with a transcriptionally inactive U2OS 2-6-3 reporter gene array provided a useful model to study SON’s chromatin dynamics. I demonstrated that SON associates with the inactive but not the activated array, and that SON’s RNA binding domains are not necessary for that association. Second, I discovered …

Green Infrastructure In Parking Lot Retrofits, Delaney Sall, Julie Wildschut

Student Papers and Reports

The built environment poses significant risks to surrounding ecosystems. Impervious surfaces like roofs, roads, and parking lots do not allow rainwater to gradually filter into the soil. Instead, runoff often flows directly into storm drains and waterways —causing flooding, erosion and pollution.

One way to mitigate these negative impacts is the installation of Green Infrastructure (GI), a variety of practices designed to infiltrate runoff into the soil, filter out pollutants, and provide habitat for native species.

Because of the way urban areas developed, most commercial parking lots lack GI. If a property owner wants to use their space to …

Fundamental Factors For Success: Engineering Faculty And Industry Partners, Molly F. Schaefer

All Graduate Theses, Dissertations, and Other Capstone Projects

Partnerships and collaborations between higher education and industry have a long history in the United States. Numerous partnerships have contributed to advancements in the economy, education and training, humanity, and innovation. The subject areas of science, engineering, and technology are fields in which many of the collaborations occur, and many of the partnerships are often initiated and led by a faculty and a member of industry. Yet, it remains unclear how academia and industry achieve successful partnerships when the goals, language, culture, and organizational structures significantly differ from one organization to another. This study examined whether partnerships among engineering faculty …

Cadent Diffusion: Permeating The Membrane, Isabella M. Kubo

Creating Reel Designs: Reflecting On Arthrogryposis Multiplex Congenita In The Community, Iris Layadi

Purdue Journal of Service-Learning and International Engagement

Because of its extreme rarity, the genetic disease arthrogryposis multiplex congenita (AMC) and the needs of individuals with the diagnosis are often overlooked. AMC refers to the development of nonprogressive contractures in disparate areas of the body and is characterized by decreased flexibility in joints, muscle atrophy, and developmental delays. Colton Darst, a seven-year-old boy from Indianapolis, Indiana, was born with the disorder, and since then, he has undergone numerous surgical interventions and continues to receive orthopedic therapy to reduce his physical limitations. His parents, Michael and Amber Darst, have hopes for him to regain his limbic motion and are …

Implementation Of Stereo Digital Image Correlation For In-Plane Strain Measurements To Quantify The Anisotropic Behavior, Plastic Flow, And Strain Hardening Of Extruded Aluminum Alloy, Farzana Yasmeen

Theses and Dissertations

The efficient use of metals is important in various industries, including aerospace, automotive, and energy systems. In each case, the type and range of combined loading conditions can be quite different. The approaches to stress analysis of such complex engineering components and assemblies often are limited to elastic conditions. For those cases where components are relatively thin, elastic-plastic conditions are present; there is continuing interest in assessing the accuracy of analytic and computational models for combined loading conditions. In such cases, experiments performed with axial and shear loads (e.g., tension-torsion) provide baseline data regarding the relationship between applied stresses and …

Build Your Own Body Mod: Empowerment Through Prototyping And Design, Anaiss Arreola, Katherine R. Ganim

Journal of Science Education for Students with Disabilities

When you don’t have a hand, what could you have instead? This article introduces the impact of inviting youth with disabilities to learn tools and technology to design their own solutions and advocate for their own future. This approach to programming is rooted in a mindset of designing WITH, not FOR. Not only are design outcomes improved when users are incorporated into the process, but this approach has been shown to improve confidence in creating one’s own solutions. These programs include hands-on “design-your-own-body-mod” workshops, as well as a budding inclusive design consultancy led by youth with disabilities. Through this programming, …

Scope Process: Fostering Students' Design Outcome Effectiveness, Andrew J. Hughes, Cameron D. Denson

Educational Leadership & Technology Faculty Publications

The purpose of this article is to help Technology and Engineering Educators scaffold engineering design and problem-solving experiences so that students taking technology and engineering courses will develop an improved ability to design. Technology and Engineering Education seems to increasingly focus on problem-solving, design, and engineering. Technology and Engineering Education is not the only discipline with this focus. The fact that both Science and Technology and Engineering Education are similarly focused on the teaching and learning of engineering begs the question of what separates technology and engineering educators from science educators in the teaching of engineering? Lewis (2004) cautioned that …

Therefore, an investigation of female-only classes was undertaken; the findings revealed that the overall enrollment of females went up in the course and in subsequent classes, these students maintained their interests and attitudes towards Technology and Engineering, their perceptions of an engineer's gender changed from that of mostly male to mostly female, and their concepts of what an engineer does changed from mostly building or …

Investigating The Habits Of Mind Of Practicing Engineers, Theresa K. Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One goal of undergraduate engineering education is to prepare students with the knowledge, skills, and decision-making strategies that are necessary for success in engineering practice. One proposed method to teach students these skills is to incorporate habits of mind into K-12 and undergraduate curricula. Habits of mind are the intelligent, social behaviors that engineers should aspire to have when solving problems, engaging with others, and dealing with uncertainty. Previous literature has suggested that incorporating ideas about habits of mind in educational curricula can teach students the disciplinary skills, technical knowledge, and social values that would help prepare them to enter …
