Men, Women, And Italians: The Masquerade Of Narrative And Identity In Richardson's Sir Charles Grandison, Ruth A. Holmes

English Theses & Dissertations

The chaotic masquerades that proliferated during the British long eighteenth century punctuated the period’s preoccupation with order and categorization. The identity categories that the masquerade disrupted, the novel reinforced, or perhaps even created. It was in the middle of this period, in the political center of Britain, that Samuel Richardson published his third and final novel, The History of Sir Charles Grandison (1753), a novel which centers England and was also centered by England, a national treasure entangled in literary and cultural history. Tracing the nexus of gender and nationalism in Grandison then becomes important given the novel’s active entanglement …

The Human That Is Not Human: Examining The Doppelganger Through David Hume, Brittnea Anne Holland

English Theses & Dissertations

The roots of horror are deeply entangled with the concepts presented through Enlightenment thinkers, especially in terms of the self and what makes a human truly a human; David Hume's essays and discussions on human nature lend themselves easily to the analysis of horror throughout the ages, particularly both in terms of what makes humanity human and in terms of metaphysical and theological concepts--and the rejection of them. This, coupled with Sigmund Freud and Otto Rank’s concepts of the uncanny, allows for the ability to perceive what makes creatures like the Doppelganger everlasting throughout humanity. Though horror as a concept …

Currently high purity niobium is the material of choice for SRF cavities which have been optimized to operate near their theoretical field limits. This brings about the need for significant R&D efforts to develop next generation superconducting materials which could outperform Nb and keep up with the demands of new accelerator facilities. To achieve high quality factors and accelerating gradients, the cavity material should be able to remain in the superconducting Meissner state under high RF magnetic field without penetration of quantized …

An Autoethnography On Teaching Antiracism In The Current Sociopolitical Environment, Taylor M. Jacobson

Teaching & Learning Theses & Dissertations

In the course of American history, students from historically marginalized and underrepresented communities have been left out of the educational conversation. This has created an era of undereducated citizens who have historically used privilege to oppress students from these communities. Teachers must use their privilege to teach antiracist education that specifically encourages students to stand up for the justice needed to make a better world. Although this education is important, politicians, parents, and school board administrators are consistently putting teachers in an awkward position when they work towards implementing antiracist education by enacting policies that force them to stop or …

End-To-End Network Slicing Using Hypergraph Theory, Omar Abdul-Latif

Theses

Network slicing is the practice of implementing multiple virtualized and independent architectures on a single physical network infrastructure, in a way that allows for multiplexing and efficient use of resources. Network slicing is based on the concept of network virtualization and, when it reaches maturity, is expected to result in complete softwarization of 5G, Beyond-5G (B5G) and 6G networks. This means that future networks will only need minimal physical infrastructure upgrades (mostly in the frontend of the network). Network slicing is identified as one of the key enablers of next generation wireless mobile networks due to its ability to multiplex …

Improved Grover’S Implementation Of Quantum Binary Neural Networks, Brody A. Wrighter

Theses

Binary Neural Networks (BNNs) are the result of a simplification of network parameters in Artificial Neural Networks (ANNs). The computational complexity of training ANNs increases significantly as the size of the network increases. This complexity can be greatly reduced if the parameters of the network are binarized. Binarization, which is a one bit quantization, can also come with complications including quantization error and information loss. The implementation of BNNs on quantum hardware could potentially provide a computational advantage over its classical counterpart. This is due to the fact that binarized parameters fit nicely to the nature of quantum hardware. Quantum …
