Molecular Cloud Properties In High-Mass Star Forming Regions, Mohammed Essa Abdulla Ali Ahli
Molecular Cloud Properties In High-Mass Star Forming Regions, Mohammed Essa Abdulla Ali Ahli
Theses
Using high spatial resolution observation of 12CO (2−1) and 13CO (2−1) emissions, I present the molecular cloud properties of N42 in the Small Magellanic Cloud. The observations were taken using the Atacama Large Millimeter Array observations. I conducted a thorough analysis of molecular gas properties to understand how the cloud properties of N42 differ from those of Galactic clouds. My analysis shows that, in N42, the majority of CO emission appears clumpy, while molecular cores with YSOs exhibit greater linewidths and masses. Massive clump cores are associated with YSOs. Virial analysis of the 12CO and 13CO …

Barriers And Facilitators To The Completion Of Advance Directives In Healthy, Non-Healthcare Employed Adults Aged 45-65, Michael Lawrence Dion
Barriers And Facilitators To The Completion Of Advance Directives In Healthy, Non-Healthcare Employed Adults Aged 45-65, Michael Lawrence Dion
Theses
The Patient Self-Determination Act passed in 1991 requires staff in health care facilities, such as skilled nursing facilities, hospitals, home health services and primary care offices to ask patients about advanced directives. Despite this, actual completions of advance directives in America remain low. To determine the barriers and facilitators to the completion of advance directives in healthy, non-health care employed individuals aged 45-65. It is believed healthy individuals in this age group both desire the advance directive, and have strong opinions regarding their end of life preferences.

Towards Efficient Lifelong Machine Learning In Deep Neural Networks, Tyler L. Hayes
Towards Efficient Lifelong Machine Learning In Deep Neural Networks, Tyler L. Hayes
Theses
Humans continually learn and adapt to new knowledge and environments throughout their lifetimes. Rarely does learning new information cause humans to catastrophically forget previous knowledge. While deep neural networks (DNNs) now rival human performance on several supervised machine perception tasks, when updated on changing data distributions, they catastrophically forget previous knowledge. Enabling DNNs to learn new information over time opens the door for new applications such as self-driving cars that adapt to seasonal changes or smartphones that adapt to changing user preferences. In this dissertation, we propose new methods and experimental paradigms for efficiently training continual DNNs without forgetting. We …

Lightness, Brightness, And Transparency In Optical See-Through Augmented Reality, Lili Zhang
Theses
Augmented reality (AR), as a key component of the future metaverse, has leaped from the research labs to the consumer and enterprise markets. AR optical see-through (OST) devices utilize transparent optical combiners to provide visibility of the real environment as well as superimpose virtual content on top of it. OST displays distinct from existing media because of their optical additivity, meaning the light reaching the eyes is composed of both virtual content and real background. The composition results in the intended virtual colors being distorted and perceived transparent. When the luminance of the virtual content decreases, the perceived lightness and …

Convection In High-Mass And Low-Mass Common Envelopes, Emily C. Wilson
Convection In High-Mass And Low-Mass Common Envelopes, Emily C. Wilson
Theses
While isolated stars evolve in fairly predictable ways, the evolution of a binary star (i.e., a pair of stars) is not as well understood. Many close binary systems undergo a phase of evolution wherein one star engulfs the other such that both stars share a common stellar envelope. During this phase, the orbital distance between the two stars rapidly shrinks by a factor of 100-1000 in approximately 1-10 years. As a result of this so-called “inspiral,” the companion deposits energy into the envelope until the shared envelope itself becomes gravitationally unbound and is ejected from the system. The efficiency with …
