Refining The Inverse Lipschitz Constant For Injective Relu Networks, Cole Rausch Jan 2024

Refining The Inverse Lipschitz Constant For Injective Relu Networks, Cole Rausch

Electronic Theses and Dissertations

In this thesis, we study the Inverse Lipschitz Constant (ILC) of injective ReLU layers. We study the tightness of the ILC lower bound established in Puthawala et al. Our approach has three components. First, we find that the conditions for injectivity on lines yield a weaker condition than the general condition given in Puthawala et al. Second, we perform numerical experiments to judge the tightness of the existing ILC lower bound and find that bound is overly conservative. Third, we identify the source of the potential slack in the proof of the existing ILC bound, and perform further numerical experiments …

Reimagining Hunting Through Women's Decision Space, H. Nash Jackson Jan 2024

Reimagining Hunting Through Women's Decision Space, H. Nash Jackson

Electronic Theses and Dissertations

Approximately 14.4 million people hunt in the United States, yet only 3.1 million (22%) of these hunters are women. To enhance women’s participation, many state natural resource agencies aim to reduce barriers and create pathways for women to hunt. Previously, researchers surveyed women to understand and describe barriers to their full participation in hunting. However, this methodology often just quantifies the different barriers without describing the interconnectedness and how the complexity of barriers can impact women’s participation in hunting. This thesis instead took an inductive research approach with the goal of better understanding women’s perspectives when faced with complex barriers. …


Computational Characterization Of Extracellular Electro-Osmotic Flow During Tissue Repair, Ashley Jorgensen-Blocker Jan 2024

Computational Characterization Of Extracellular Electro-Osmotic Flow During Tissue Repair, Ashley Jorgensen-Blocker

Electronic Theses and Dissertations

Electrical stimulation (ES) therapy promotes the healing of chronic epidermal wounds and suppresses the degeneration of articular cartilage. Despite the success of ES therapy, the underlying mechanisms by which ES promotes tissue repair are largely unknown, preventing the standardization and optimization of treatments. One proposed mechanism involves electro-osmotic flow (EOF), electrically driven water flow generated within close proximity to the cell surface. EOF induces the transport of macromolecules and removes metabolic wastes and inflammatory molecules from these dense tissues through interstitial flow. This dissertation investigates the application of weak electric fields (EFs) to non-excitable cells and the generation of EOF …
