An Exploration Of Style Transfer Using Deep Neural Networks, Cameron Y. Smith

Computer Science ETDs

Convolutional Neural Networks and Graphics Processing Units have been at the core of a paradigm shift in computer vision research that some researchers have called `'the algorithmic perception revolution." This thesis presents the implementation and analysis of several techniques for performing artistic style transfer using a Convolutional Neural Network architecture trained for large-scale image recognition tasks. We present an implementation of an existing algorithm for artistic style transfer in images and video. The neural algorithm separates and recombines the style and content of arbitrary images. Additionally, we present an extension of the algorithm to perform weighted artistic style transfer.

Connecting Self-Efficacy And Views About Nature Of Science In Undergraduate Research Experiences, Gina Quan, Andrew Elby

Faculty Publications

Undergraduate research can support students’ more central participation in physics. We analyze markers of two coupled shifts in participation: changes in students’ views about the nature of science coupled to shifts in self-efficacy toward physics research. Students in the study worked with faculty and graduate student mentors on research projects while also participating in a seminar where they learned about research and reflected on their experiences. In classroom discussions and in clinical interviews, students described gaining more nuanced views about the nature of science, specifically related to who can participate in research and what participation in research looks like. This …

An Investigation Into Spent Coffee Waste As A Renewable Source Of Bioactive Compounds And Industrially Important Sugars, Damhan Scully, Amit Jaiswal, Nissreen Abu-Ghannam

Articles

Conventional coffee brewing techniques generate vast quantities of spent espresso grounds (SEGs) rich in lignocellulose and valuable bioactives. These bioactive compounds can be exploited as a nutraceutical or used in a range of food products, while breakdown of lignocellulose generates metabolizable sugars that can be used for the production of various high-value products such as biofuels, amino acids and enzymes. Response surface methodology (RSM) was used to optimize the enzymatic saccharification of lignocellulose in SEGs following a hydrothermal pretreatment. A maximum reducing sugar yield was obtained at the following optimized hydrolysis conditions: 4.97 g of pretreated SEGs, 120 h reaction …

From Drought Monitoring To Forecasting: A Combined Dynamical-Statistical Modeling Framework, Hongxiang Yan

Dissertations and Theses

Drought is the most costly hazard among all natural disasters. Despite the significant improvements in drought modeling over the last decade, accurate provisions of drought conditions in a timely manner is still one of the major research challenges. In order to improve the current drought monitoring and forecasting skills, this study presents a hybrid system with a combination of remotely sensed data assimilation based on particle filtering and a probabilistic drought forecasting model. Besides the proposed drought monitoring system through land data assimilation, another novel aspect of this dissertation is to seek the use of data assimilation to quantify land …

Cultural Awareness In Nuclear Security Programs: A Critical Link, Al-Sharif Nasser Bin Nasser, Jasmine Auda, Katherine Bachner

International Journal of Nuclear Security

Nuclear security programs that offer training and capacity building opportunities to practitioners working in nuclear facilities play a central role in strengthening the global nuclear security architecture. There is often a significant divide, however, between both the development of these programs and their implementation, and between the programs’ intended and actual outcomes. As this article will argue, this disconnect can often be attributed to an absence of cultural awareness and an inability for internationally-designed programs to effectively resonate with local audiences. Accordingly, the importance of the role of cultural awareness in implementing nuclear security programs will be assessed, and its …

A Longitudinal Examination Of A Ssi-Embedded Experiential Environmental Education Course And Environmental Behaviors, Mark H. Newton

USF Tampa Graduate Theses and Dissertations

A perennial goal of environmental education is to produce a scientifically literate citizenry capable of negotiating and resulting complex environmental problems. Popular methods of environmental education instruction tend to overemphasize scientific content knowledge and neglect to consider ethical and moral aspects of the problem. This qualitative study examines the longitudinal association between an experiential environmental education course infused with SSI instruction and students’ environmental behaviors. The results indicate that several students’ conceptualizations of contentious environmental issues change after completing the course and specifically. Furthermore, students’ willingness to act to resolve contentious environmental issues was most closely associated with their environmental …

All-Optical Cooling Of Fermi Gases Via Pauli Inhibition Of Spontaneous Emission, Roberto Onofrio

Dartmouth Scholarship

A technique is proposed to cool Fermi gases to the regime of quantum degeneracy based on the expected inhibition of spontaneous emission due to the Pauli principle. The reduction of the linewidth for spontaneous emission originates a corresponding reduction of the Doppler temperature, which under specific conditions may give rise to a runaway process through which fermions are progressively cooled. The approach requires a combination of a magneto-optical trap as a cooling system and an optical dipole trap to enhance quantum degeneracy. This results in expected Fermi degeneracy factors T/TF comparable to the lowest values recently achieved, with potential for …

Properties Of The Schrödinger Theory Of Electrons In Electromagnetic Fields, Viraht Sahni, Xiao-Yin Pan

Publications and Research

The Schrödinger theory of electrons in an external electromagnetic field can be described from the perspective of the individual electron via the ‘Quantal Newtonian’ laws (or differential virial theorems). These laws are in terms of ‘classical’ fields whose sources are quantal expectations of Hermitian operators taken with respect to the wave function. The laws reveal the following physics: (a) In addition to the external field, each electron experiences an internal field whose components are representative of a specific property of the system such as the correlations due to the Pauli exclusion principle and Coulomb repulsion, the electron density, kinetic effects, …

A Gis Analysis Of Waulsortian-Like Mounds In The Mississippian Of Kentucky And Tennessee, Philip Roberson

Scholars Week

Following a mass extinction nearly 365 million years ago, bryozoans and crinoids replaced corals and stromatoporoids as the dominant framework organisms in reefs and, during the very earliest part of the Carboniferous period, they built reef-like structures that are known from Europe, North America and Africa. They are characterized by large size, a matrix of carbonate mud, and their major framework organisms.

Waulsortian-like mounds occur in geographically isolated patches in outcrop and in the subsurface of central Tennessee and Kentucky where they are associated with hydrocarbon production. These mounds have the same characteristic organisms as the European mounds and do …

Commercial Space Situational Awareness (Ssa) Capabilities And Their Benefits For Civilian Space Traffic Management (Stm), Mark A. Skinner

Space Traffic Management Conference

Paralleling (but lagging) satellite development, SSA, long the sole domain of sophisticated militaries, now includes commercial providers. These commercial capabilities, identified as beneficial to the sustainable use of outer space[1], have demonstrated technical sophistication sufficient to positively contribute to the mitigation of satellite interference and provide actionable SSA information. Utilizing small optical telescopes, these entities are able to determine the orbits of objects in the geosynchronous orbit (GSO) to sizes as small as 1 m², with measured positional uncertainties of 10s of meters, on the order of the size of a modern communications satellite. These techniques …

Using Sensitivity Analyses For Unobserved Confounding To Address Covariate Measurement Error In Propensity Score Methods, Kara E. Rudolph, Elizabeth A. Stuart

Johns Hopkins University, Dept. of Biostatistics Working Papers

Propensity score methods are a popular tool to control for confounding in observational data, but their bias-reduction properties are threatened by covariate measurement error. There are few easy-to-implement methods to correct for such bias. We describe and demonstrate how existing sensitivity analyses for unobserved confounding---propensity score calibration, Vanderweele and Arah's bias formulas, and Rosenbaum's sensitivity analysis---can be adapted to address this problem. In a simulation study, we examined the extent to which these sensitivity analyses can correct for several measurement error structures: classical, systematic differential, and heteroscedastic covariate measurement error. We then apply these approaches to address covariate measurement error …

Personal Reflections / 11.18.16, José M. Torres

Personal Reflections

It’s been an eventful time since the Cubs won the World Series! It was amazing to see 5 million people celebrate the Cub’s victory. Hopefully we won’t have to wait another 108 years to relive the experience. Last week we had a historic election and now, our country will transition power from President Obama to President-elect Trump.

Heightened discourse followed this historic election and rising tensions and fears are being experienced, especially by minorities, immigrants, refugees and others groups. IMSA will remain the safe and welcoming place that it’s always been for 30 years. Our counselors are available for our …

Results Of The Deepest All-Sky Survey For Continuous Gravitational Waves On Ligo S6 Data Running On The Einstein@Home Volunteer Distributed Computing Project, B. P. Abbott, R. Abbott, T. D. Abbott, M. R. Abernathy, Teviet Creighton, Mario C. Diaz, Soma Mukherjee, Volker Quetschke, Malik Rakhmanov

Physics & Astronomy Faculty Publications

We report results of a deep all-sky search for periodic gravitational waves from isolated neutron stars in data from the S6 LIGO science run. The search was possible thanks to the computing power provided by the volunteers of the Einstein@Home distributed computing project. We find no significant signal candidate and set the most stringent upper limits to date on the amplitude of gravitational wave signals from the target population. At the frequency of best strain sensitivity, between 170.5 and 171 Hz we set a 90% confidence upper limit of 5.5×10-25, while at the high end of our frequency range, around …

Relaxation In Bolted Assemblies, Samuel Augustus Moeller

Theses and Dissertations

The purposes of this investigation were to (a) extend previously developed elastic spring models for bolt assemblies to include simulating creep loss in the bolt and the threads and (b) to present an approach in which appropriate spring stiffness in the model are determined rationally. Previous efforts at modeling tension in bolts have been limited in that they were not readily applicable to analyses of realistic bolted connections. The simulated load distributions on the shank and the threads in a single-bolt assembly showed good comparison to the gathered experimental data as did the simulated, time dependent creep loss in the …

Tracking Earthquake Frequency And Intensity In Oklahoma, Kristin Lorenzini

Scholars Week

The purpose of this project is to show the dramatic increase of earthquakes that have occurred in Oklahoma over the past eight years that have been correlated to fracking in the area. Starting in 2009, before fracking took place in Oklahoma, there were a total of 33 earthquakes throughout the whole year. In 2010, when fracking began in Oklahoma, the number of earthquakes spiked to over 100 in one year. The number of earthquakes grew over the years and in 2015 there were over 2,000. Data from 2016 were also used but only through the month of September, the year …
