Adaptive Optics Simulations for Siding Spring
Using an observational derived model optical turbulence profile (model-OTP)
we have investigated the performance of Adaptive Optics (AO) at Siding Spring
Observatory (SSO), Australia. The simulations cover the performance for AO
techniques of single conjugate adaptive optics (SCAO), multi-conjugate adaptive
optics (MCAO) and ground-layer adaptive optics (GLAO). The simulation results
presented in this paper predict the performance of these AO techniques as
applied to the Australian National University (ANU) 2.3 m and Anglo-Australian
Telescope (AAT) 3.9 m telescopes for astronomical wavelength bands J, H and K.
The results indicate that AO performance is best for the longer wavelengths
(K-band) and in the best seeing conditions (sub 1-arcsecond). The most
promising results are found for GLAO simulations (field of view of 180
arcsecs), with the field RMS for encircled energy 50% diameter (EE50d) being
uniform and minimally affected by the free-atmosphere turbulence. The GLAO
performance is reasonably good over the wavelength bands of J, H and K. The
GLAO field mean of EE50d is between 200 mas to 800 mas, which is a noticeable
improvement compared to the nominal astronomical seeing (870 to 1700 mas).Comment: 15 pages; accepted for publication in PAS
Improving single use bioreactor design and process development using the HyPerforma 5:1 S.U.B
Operating bioreactor vessels at low working volumes (high turn-down ratio) is often desirable but brings about challenges in regard to mixing, mass transfer, and process control. Research done towards optimizing cell culture has provided methods to improve performance and control when operating under these special conditions. Impacts of enhanced energy transfer-Implementing bottom heat exchange, alternate impeller positions, and considering agitation dissipation rates. Maximizing your platform-Taking advantage of the unique Thermo Fisher Scientific Drilled Hole Sparge design and implementing a new Cross Flow Sparge into the headspace have yielded reliable mass transfer and cell culture results from 10-2000L working volumes. Improving bioprocess production–How new technology improves equipment utilization, scheduling efficiency, inventory logistics, and reactor harvest consistency. Operating at 5:1 Turn Down with the new 1000L and 2000L Hyperforma S.U.B. - cGMP operating considerations, design features, implementing enhanced processing tool
Two Is the Oddest Number: Same-Sex Marriage and the Victorian Afterlife
This dissertation reads today's same-sex marriage debate in United States in relation to the English debates over marriage reform in the 1850s. In particular, it focuses on the postmodern afterlife of the Victorian, arguing that the Victorian afterlife merges deeply suspicious readings with reparative ones. Starting with John Stuart Mill's "The Subjection of Women," it examines the manner in which today's readings of Mill's treatise repeat the responses of Mill's contemporaries. The paranoid reactions of today's readers attempt to show the inadequacies and contradictions of Mill's liberalism. At the same time, they highlight the paradoxical quality of Mill's "ideal of marriage," which involves "two persons of cultivated faculties, identical in opinions and purposes, between whom there exists that best of equality, similarity of powers and capacities with reciprocal superiority." In other words, "I am superior to you at the very same time that you are superior to me." So the desire for reciprocal superiority to embrace the supposedly non-paranoid, utopic celebrations surrounding the phenomenon of same-sex marriage, while it also reminds us not to dispense with paranoia, since these promises are pure fantasy.
The volatile relationship between these opposing reading practices (the paranoid and the reparative) helps us to identify the impossibility of true marriage equality. In order to highlight their dialectical relationship, subsequent chapters focus on the paranoid and reparative qualities of two contradictory critical readings of Charles Dickens's "David Copperfield"; on "Little Dorrit" and its same-sex couple (Miss Wade and Tattycoram); on Walter Pater's hagiography of Winckelmann; and, finally, on Oscar Wilde's "The Importance of Being Earnest" and what I call Eve Kosofsky Sedgwick's "reparative avunculate,' that is, the alternative familial relations that flit upon the play's surface but get ignored by paranoid scholars focusing solely on the psychoanalytic triad of the father-mother-child. While the "reparative avunculate" is comprised by Algernon's cynical, paranoid insistence that "two is none," it is a necessary addition to Wilde's farcical portrayal of bourgeois marriage. Taken together, paranoid and reparative analyses demonstrate there is no such thing as an anti-hierarchical, egalitarian, non-zero-sum, two-person partnership, although we continue to desire such partnerships
Cacophony: Stories
Cacophony: Stories was written over three years in the Center for Writers at the University of Southern Mississippi. The collection depicts middle-class characters disconnected from relationships, careers, and family. Each story explores disillusioned characters forced to confront a major moment in their lives from a bleak setting. Characters find varying degrees of success in forging an identity in the face of flawed existence. This existence lingers, producing an apathetic lifestyle where characters must act. These characters act passively through the narrative and the collection sees them forced to break away from their malaise. The collection aims to explore austere suburban life, removing middle-class virtue to uncover a layer of despondency fraught with social, cultural, economic, and environmental complications
