Application Of Deep Learning On Gage R&R For Anomaly Detection, Oluwatope Richard Ojo

Electronic Theses and Dissertations

This thesis explores the application of deep learning techniques, specifically autoencoder based models, to enhance anomaly detection within Gage Repeatability and Reproducibility (Gage R&R) studies—an essential component of Measurement System Analysis (MSA) in quality engineering. Traditional Gage R&R methodologies, while effective for linear and low-dimensional data, exhibit limitations in detecting subtle, nonlinear variations in complex measurement systems. To address this challenge, an unsupervised autoencoder was developed and trained on a synthetically generated dataset comprising 2,500 voltage measurements (5V and 33V) derived using Generative Adversarial Networks (GANs) based on real-world manufacturing data measurements.

The proposed autoencoder model achieved a 95th percentile-based …

Inferring Feeding Biology In Extinct Shrews (Soricidae: Mammalia): Application Of A Linear Morphometric Approach, Derek J. Den Ouden

Electronic Theses and Dissertations

Linear morphometrics have been used extensively to infer the ecology of fossil organisms, but shrews have not yet been thoroughly explored using this technique. Often considered to have a homogenous insectivorous diet, direct dietary observation suggests shrew dietary diversity is substantial. Diversity of this nature is well established to have influenced skull morphology in other mammal clades, so similar patterns are hypothesized to be detectable in shrews. To test this, I examined the link between known diet and morphological disparity in extant shrews using linear morphometrics and then utilized that framework to infer the dietary ecology of several fossil taxa. …

Mediation analyses revealed that perceived social support mediates the relationship between ACEs and both anxiety and depression. Moderated mediation analyses further indicated that …

Exploring Young Adults’ Implicit Theories Of Emotion And Emotion Dysregulation On Parental Emotion Socialization And Internalizing Symptomology, Daryl Parungao

Electronic Theses and Dissertations

Research regarding emotion socialization suggests parents’ responses towards their children’s negative emotions, which may be characterized as either emotion dismissive or emotion coaching behaviors, are associated with children’s well-being into adulthood. A heuristic model of emotion socialization suggests that child-level factors related to emotion processing may moderate this association (Eisenberg, 1998), which warrants further examination when considering relevant risk factors for mental health disorders such as anxiety and depression. This dissertation explored how parent emotion socialization responses interact with young adults’ beliefs about the controllability of emotions and their difficulties with emotion regulation with regard to their impact on young …

“With Neither Hope Nor Fear”: Continuity In The Life Of Isabella D’Este, Alyssa Murphy

Electronic Theses and Dissertations

Isabella d’Este is traditionally viewed as the most notable female art patron of Renaissance Italy, primarily studied for her excellent taste. This positive interpretation has left her out of the reputational rehabilitation that modern historians have applied to many of her contemporaries, and what recent work has been done focuses on her marriage. However, Isabella outlived her husband by nearly twenty years, and contrary to writers who view that widowhood as an afterthought, she remained a dominant political and cultural figure in her own right. This thesis reassesses Isabella’s letters to argue that the traditional segmentation of her life does …
