Dynamic Deformation and Shear Localization in Friction-Stir Processed Al0.3CoCrFeNi and Fe50Mn30Co10Cr10 High-Entropy Alloys

Description: High entropy alloys (HEAs) are a relatively new class of solid solution alloys that contain multiple principal elements to take advantage of their high configurational entropy, sluggish diffusion, lattice distortion, and the cocktail effect. In recent development, work hardening mechanisms known as twinning induced plasticity (TWIP) and transformation induced plasticity (TRIP) have been found active in Al0.3CoCrFeNi (molar fraction) and Fe50Mn30Co10Cr10 (at %) HEA compositions. Friction-stir pr… more

Gradual: A Sound-Based Composition for Tenor Saxophone and Fixed Electronics, with Critical Essay

Description: In the first half of the twentieth century, sporadic attempts of avant-garde composers to include sounds other than pitch in musical composition paved the way for the composers in the second half to embrace the sound of all types in their creative works. The development of technology since the mid-past century has facilitated composers' inclusive use of sound. The recent achievements in electronics and computers have led to cost-effective tools for today's composers to explore new possibilities… more

Audiovisual Concatenative Synthesis and "Replica"

Description: Audiovisual concatenative synthesis is an analysis-driven granular technique using a corpus of multimedia data to sequence audio and video streams on a microtemporal level. This text outlines my development of this technique as a tool for multimedia composition, using my work, Replica, as a case study. The paper illustrates how the concepts of granular structure, gesture capture, and replication are integral not only to the software but to the architecture of the composition. In doing so, machi… more

Military and Veteran Mental Health Stigma and Help-Seeking Behaviors: Role of Leadership and Attachment

Description: Mental health stigma has been identified as a barrier to help-seeking in the United States. Research suggests that insecure attachment may contribute to higher mental health stigma and lower help-seeking behavior. This may be particularly salient in military personnel who tend to report higher mental health stigma than the general population. Evidence suggests that both supportive and destructive military leadership are related to service members' attitudes toward seeking help. In the current s… more

The Conceptual Autopoiēsis of Language-Habits and Language-Cultures that Orient Humans as Separate from Nature

Description: In this dissertation I consider the nature of the relationship between orientation and language-habits in the context of environmental ethics. Specifically, I focus on the problem of orientation as a way of understanding the unabated trend of anthropocentrism in the dominant Western language-culture. Orientation operates as the attitudes, beliefs, and feelings in relation to something that we embody in our lived experiences. One way that we communicate our orientation in relation to the land is… more

Improving Actigraphy Specificity to Better Inform Insomnia Diagnosis and Treatment Decisions

Description: Accurate assessment of sleep-wake patterns is important for sleep researchers and clinicians. Actigraphs are low-cost, non-intrusive, wrist-worn activity detectors used to estimate sleep-wake patterns in a natural environment for several nights. Although actigraphy shows good sensitivity (sleep detection), it has consistently demonstrated poor specificity (wakefulness detection while lying in bed relatively motionless). Because insomnia is characterized by wakefulness in bed, actigraphy may not… more

Carbon Nanotubes and Molybdenum Disulfide Protected Electrodes for High Performance Lithium-Sulfur Battery Applications

Description: Lithium-sulfur (Li-S) batteries are faced with practical drawbacks of poor cycle life and low charge efficiency which hinder their advancements. Those drawbacks are primarily caused by the intrinsic issues of the cathodes (sulfur) and the anodes (Li metal). In attempt to resolve the issues found on the cathodes, this work discusses the method to prepare a binder-free three-dimensional carbon nanotubes-sulfur (3D CNTs-S) composite cathode by a facile and a scalable approach. Here, the 3D structu… more
