Electrically Induced Plasma, Nate Ashby

Physics Capstone Projects

My research project, under the mentorship of research professor Ajay Singh was to prove that the plasma he was creating was lasting longer than the electrical current data indicated. He decided that if the plasma was still there, it would be producing light. So we set out to prove that the light emitted from his plasma lasted longer than the current draw measurements.

Precise Detection Of Injection Attacks On Concrete Systems, Clayton Whitelaw

USF Tampa Graduate Theses and Dissertations

Injection attacks, including SQL injection, cross-site scripting, and operating system command injection, rank the top two entries in the MITRE Common Vulnerability Enumeration (CVE) [1]. Under this attack model, an application (e.g., a web application) uses some untrusted input to produce an output program (e.g., a SQL query). Applications may be vulnerable to injection attacks because the untrusted input may alter the output program in malicious ways. Recent work has established a rigorous definition of injection attacks. Injections are benign iff they obey the NIE property, which states that injected symbols strictly insert or expand noncode tokens in the output …

A Comparative Study Of Formal Verification Techniques For Authentication Protocols, Hernan Miguel Palombo

USF Tampa Graduate Theses and Dissertations

Protocol verification is an exciting area of network security that intersects engineering and formal methods. This thesis presents a comparison of formal verification tools for security protocols for their respective strengths and weaknesses supported by the results from several case studies. The formal verification tools considered are based on explicit model checking (SPIN), symbolic analysis (Proverif) and theorem proving (Coq). We formalize and provide models of several well-known authentication and key-establishment protocols in each of the specification languages, and use the tools to find attacks that show protocols insecurity. We contrast the modelling process on each of the tools by …

Study Of Multiband Disordered Systems Using The Typical Medium Dynamical Cluster Approximation, Yi Zhang, Hanna Terletska, C. Moore, Chinedu Ekuma, Ka Ming Tam, Tom Berlijn, Wei Ku, Juana Moreno, Mark Jarrell

Faculty Publications

We generalize the typical medium dynamical cluster approximation to multiband disordered systems. Using our extended formalism, we perform a systematic study of the nonlocal correlation effects induced by disorder on the density of states and the mobility edge of the three-dimensional two-band Anderson model. We include interband and intraband hopping and an intraband disorder potential. Our results are consistent with those obtained by the transfer matrix and the kernel polynomial methods. We apply the method to KxFe2-ySe2 with Fe vacancies. Despite the strong vacancy disorder and anisotropy, we find the material is not an Anderson insulator. Our results demonstrate the …

Stochastic Models For Plant Microtubule Self-Organization And Structure, Ezgi Can Eren, Ram Dixit, Natarajan Gautam

Biology Faculty Research

One of the key enablers of shape and growth in plant cells is the cortical microtubule (CMT) system, which is a polymer array that forms an appropriately-structured scaffolding in each cell. Plant biologists have shown that stochastic dynamics and simple rules of interactions between CMTs can lead to a coaligned CMT array structure. However, the mechanisms and conditions that cause CMT arrays to become organized are not well understood. It is prohibitively time-consuming to use actual plants to study the effect of various genetic mutations and environmental conditions on CMT self-organization. In fact, even computer simulations with multiple replications are …

Comparison Of Otolith-Based Growth Rates And Microchemistry In Red Drum Before, During, And After The Deepwater Horizon Oil Spill, Brock Charles Houston

USF Tampa Graduate Theses and Dissertations

Oil from the Deepwater Horizon blowout reached the Gulf of Mexico coast in the summer of 2010 and potentially exposed species living in those areas to toxic chemicals. The purpose of this study is to examine otoliths from Red Drum (Sciaenops ocellatus) for evidence of oil exposure that could be related to reduced growth rates. Because otolith growth and somatic growth are directly related, differences in annulus measurements can indicate differences in annual somatic growth, which is a good indicator of overall fish condition, and translates into changes in survival and lifetime reproductive potential. This study assessed variation …

Model-Based Analytics And Processes For Transportation Investment Alternatives Analyses: From Least Cost Planning To Multi Criterion Evaluation, Jeff Frkonja

PSU Transportation Seminars

Many public and private organizations that make decisions regarding whether and how to invest in transportation assets or programs do so via a structured decision-support process. This talk will address the technical aspects of the family of such processes that use travel demand model outputs—and other sources of quantified performance data—as inputs to analytic tools including benefit cost analysis (BCA) and multi criterion evaluation. Example applications of this framework have included tolling and pricing studies, capital investment alternatives analyses, and programmatic evaluations. Example processes include "Least Cost Planning" frameworks borrowed originally from the power generation industry.

The talk will also …

Gravitons To Photons--Attenuation Of Gravitational Waves, Preston Jones, Douglas Singleton

Publications

In this essay, we examine the response of an Unruh–DeWitt (UD) detector (a quantum two-level system) to a gravitational wave background. The spectrum of the UD detector is of the same form as some scattering processes or three body decays such as muon-electron scattering or muon decay. Based on this similarity, we propose that the UD detector response implies a “decay” or attenuation of gravitons, G, into photons, γ, via G+G→γ+γ or G→γ+γ+G. Over large distances such a decay/attenuation may have consequences in regard to the detection of gravitational waves.

Explaining The Varying Success Of Radical Right Parties In European Union And National Elections, Jakub Wondreys

Research Papers

In this study, I try to explain-as other scholars have-the growing success of radical right parties in Europe. I also address conceptualization and classification issues. Contrary to other scholars, I compare party performance across two different elections: European and National. Also unlike the vast majority of studies that focus exclusively on Western Europe, this study looks more broadly at all members of the European Union, including those in Central Eastern Europe. My main argument is that radical right will perform better in European than in national elections. In explaining why parties should perform better in the former rather than the …

A New Extension Of The Binomial Error Model For Responses To Items Of Varying Difficulty In Educational Testing And Attitude Surveys, James A. Wiley, John Levi Martin, Stephen J. Herschkorn, Jason Bond

Publications and Research

We put forward a new item response model which is an extension of the binomial error model first introduced by Keats and Lord. Like the binomial error model, the basic latent variable can be interpreted as a probability of responding in a certain way to an arbitrarily specified item. For a set of dichotomous items, this model gives predictions that are similar to other single parameter IRT models (such as the Rasch model) but has certain advantages in more complex cases. The first is that in specifying a flexible two-parameter Beta distribution for the latent variable, it is easy to …

Interpret The Numbers: Putting E-Book Usage Statistics In Context, Maria Savova, Madelynn Dickerson

Library Staff Publications and Research

E-books have been an integral part of library collections for a long time now, but they are still surrounded by controversy. How much our patrons really use them? That seemingly simple question has a very complicated answer that could depend on a number of factors. The e-books’ usage reports mean very little on their own and leave many unanswered questions. In order to contextualize the usage statistics, the Claremont Colleges Library conducted an analysis of enhanced usage reports in comparison with the total offerings of e-book content available to our users from all major providers, and through all access models. …

Development Of Truck Route Choice Data Using Truck Gps, Mohammadreza Kamali

USF Tampa Graduate Theses and Dissertations

Over the past few decades, the value and weight of freight shipments have grown steadily in both developed and developing countries. A recent statistic in the U.S. reveals that weight of shipments increased from 18,879 to 19,662 million tons between 2007 and 2012 (1). It is also expected that this amount will increase to 28,520 million tons by 2040 (1). It is worth mentioning that 67 percent of shipments are shipped by truck mode in 2012. The monetary value of freight is expected to escalate even faster than weight. This value is estimated to rise from US$ 882 per ton …

A Study On The Integration Of Multivariate Metocean, Ocean Circulation, And Trajectory Modeling Data With Static Geographic Information Systems For Better Marine Resources Management And Protection During Coastal Oil Spill Response – A Case Study And Gap Analysis On Northeastern Gulf Of Mexico Tidal Inlets, Richard Ray Knudsen

USF Tampa Graduate Theses and Dissertations

The Oil Pollution Act of 1990 requires the development of Regional and Area Contingency Plans. For more than 20 years, the State of Florida, under both the Department of Environmental Protection and the Florida Fish and Wildlife Commission, has worked closely with the U.S. Coast Guard and the National Oceanic and Atmospheric Administration to develop these plans for coastal and marine oil spill response. Current plans, developed with local, state and federal stakeholder input, use geographic information systems (GIS) data such as location and extent of sensitive ecological, wildlife, and human-use features (termed Environmental Sensitivity Index data), pre-defined protection priorities, …

Understanding Climate Change And Sea Level: A Case Study Of Middle School Student Comprehension And An Evaluation Of Tide Gauges Off The Panama Canal In The Pacific Ocean And Caribbean Sea, Juan Carlos Millan-Otoya

USF Tampa Graduate Theses and Dissertations

The present study had two main objectives. The first was to determine the degree of understanding of climate change, sea level and sea level rise among middle school students. Combining open-ended questions with likert-scaled questions, we identified student conceptions on these topics in 86 students from 7^th and 8^th grades during 2012 and 2013 before and after implementing a Curriculum Unit (CU). Additional information was obtained by adding drawings to the open-ended questions during the second year to gauge how student conceptions varied from a verbal and a visual perspective. Misconceptions were identified both pre- and post-CU among …

Existence Of Noncontractible Periodic Orbits Of Hamiltonian System Separating Two Lagrangian Tori On T*��N, Jinxin Xue

Dynamical Systems Seminar

In this talk, we show the existence of non contractible periodic orbits in Hamiltonian systems defined on T*��n separating two Lagrangian tori under certain cone assumption. Our result answers a question of Polterovich (Symplectic intersections and invariant measures, Annales mathematiques du Quebec (2014)). As an application, we find periodic orbits of almost all the homotopy types on a dense set of energy level in Lorentzian type mechanical Hamiltonian system. This solves a problem of Arnold (Mathematical problems in classical physics. Trends and perspectives in applied mathematics, Appl. Math. Sci., vol. 100, Springer, New York, (1994)).

Assessing Density Functionals For The Prediction Of Thermochemistry Of Ti-O-Cl Species, Yingbin Ge, Douglas Deprekel, Kui-Ting Lam, Kevin Ngo, Phu Vo

All Faculty Scholarship for the College of the Sciences

Titanium dioxide (TiO2) nanoparticles are widely used in contaminant remediation, photocatalysis, and solar cell manufacturing. The low-cost production of TiO2 nanoparticles via the combustion of titanium tetrachloride (TiCl4) in oxygen is thus an important industrial process. To accurately model the flame synthesis of TiO2 nanoparticles, reliable thermodynamic data of Ti-O-Cl species are indispensable but often unavailable. We therefore carried out benchmark calculations, using the left-eigenstate completely renormalized singles, doubles, and perturbative triples (CR-CC(2,3), aka CR-CCL) method with the cc-pVTZ basis set, to obtain the equilibrium structures and vibrational frequencies of selected Ti-O-Cl species; we then performed single-point CCSD(T)/aug-cc-pVLZ …

Global Trends In Higher Education Policies, Kathryn Moyle

Initial Teacher education

This paper outlines the current global context for higher education in 2015, as a basis for examining the key trends in teacher education in the first decades of the 21st century. The purpose of this paper is to outline the current global contexts for higher education, and to provide an overview of the policies found in teacher education in those countries that consistently produce students who perform highly on international standardized tests such as PISA, TIMSS and PIRLS. The policies guiding teacher education in ‘high-performing’ countries tends to be aligned and inter-connected. These policies include public investment in education; creating …

Homogeneous Cosmology With Aggressively Expanding Civilizations, S. Jay Olson

Physics Faculty Publications and Presentations

In the context of a homogeneous Universe, we note that the appearance of aggressively expanding advanced life is geometrically similar to the process of nucleation and bubble growth in a first-order cosmological phase transition. We exploit this similarity to describe the dynamics of life saturating the Universe on a cosmic scale, adapting the phase transition model to incorporate probability distributions of expansion and resource consumption strategies. Through a series of numerical solutions spanning several orders of magnitude in the input assumption parameters, the resulting cosmological model is used to address basic questions related to the intergalactic spreading of life, dealing …
