Computational Modeling Of Biochemical Systems Using Cellular Automata, Advait Apte

Theses and Dissertations

Biological systems exhibit complex behaviors through coordinated responses of individual biological components. With the advent of genome-scale techniques, one focus has been to develop methods to model interactions between components to accurately describe intact system function. Mathematical modeling techniques such as constraint-based modeling, agent-based modeling, cellular automata (CA) modeling and differential equation modeling are employed as computational tools to study biological phenomenon. We have shown that cellular automata simulations can be used as a computational tool for 12 predicting the dynamics of biological systems with stochastic behavior. The basic premise for the research was the observations made during a study …

The Effectiveness Of Prevent-Teach-Reinforce: Does The Presence Of Comorbid Internalizing Behavior Problems Moderate Outcomes For Children With Externalizing Behavior Problems?, Bonnie Saari

USF Tampa Graduate Theses and Dissertations

This study examined the effectiveness of a school-based intervention process known as Prevent-Teach-Reinforce for children with a combination of externalizing and internalizing behaviors compared to children with only externalizing behaviors. The dependent variables examined were social skills, problem behaviors, and academic engaged time. Data for the current study were taken from archival data collected by the Florida Mental Health Institute that included students in kindergarten through 8th grade. A series of repeated-measures analysis of variance (ANOVA) was used to identify differences in improvement on the dependent variables for the two groups of students.

The Ecological Advantages Of Nuclear Power, Fred P. Bosselman

All Faculty Scholarship

Major electric utilities are deciding whether to build nuclear power plants. How will their decision affect ecological processes and systems, both in the United States and globally? The article makes three arguments: (1) if nuclear power plants are not built, the gap will be filled by more coal-fired power plants; (2) the impact of coal-fired power plants on ecological processes and systems is likely to be increasingly disastrous; and (3) nuclear power’s ecological impacts are likely to be neutral or even positive.

Fractal Location And Anomalous Diffusion Dynamics For Oil Wells From The Ky Geological Survey, Keith Andrew, Karla M. Andrew, Kevin A. Andrew

Physics & Astronomy Faculty Publications

Utilizing data available from the Kentucky Geonet (KYGeonet.ky.gov) the fossil fuel mining locations created by the Kentucky Geological Survey geo-locating oil and gas wells are mapped using ESRI ArcGIS in Kentucky single plain 1602 ft projection. This data was then exported into a spreadsheet showing latitude and longitude for each point to be used for modeling at different scales to determine the fractal dimension of the set. Following the porosity and diffusivity studies of Tarafdar and Roy[1] we extract fractal dimensions of the fossil fuel mining locations and search for evidence of scaling laws for the set of deposits.

Masters Theses, 2010-2019

Offshore wind power is an increasingly viable resource that is being considered by many coastal States in the U.S for development. This thesis provides a recommendation concerning the foundations that will be needed for the construction of offshore wind farms off the coast of Virginia. To accomplish this I reviewed current and prototype underwater foundation technologies in order to establish viable options for developers to use. I was also able to analyze a case study that conducted “an analysis and survey of the experiences and lessons learned by developers of offshore wind farms” in Europe. This case study focuses mainly …

A Simulation Model For Triclosan Concentrations In The North And Middle Rivers, Virginia, Preeyaporn Songkiatisak

Masters Theses, 2010-2019

Incidences of fish kills and intersex phenomena have occurred extensively in the Shenandoah River since 2004. Pharmaceuticals including triclosan have been detected at low concentrations in the Shenandoah River. Scientists hypothesize that triclosan, an antibacterial agent, may be one of the pharmaceuticals that is responsible for fish kills and intersex phenomena. Methyl triclosan (MTS) were found in fish tissues at a significantly higher concentration in the part of the Shenandoah River where fish kills are present compared to a non-impact river. Triclosan is widely used in personal care products, such as soaps, shampoos, and toothpastes and is rinsed down the …

Optimal Cryptographic Hardness Of Learning Monotone Functions, Dana Dachman-Soled, Homin K. Lee, Tal Malkin, Rocco A. Servedio, Andrew Wan, Hoeteck Wee

Publications and Research

Over the years a range of positive algorithmic results have been obtained for learning various classes of monotone Boolean functions from uniformly distributed random examples. Prior to our work, however, the only negative result for learning monotone functions in this model has been an information-theoretic lower bound showing that certain super-polynomial-size monotone circuits cannot be learned to accuracy 1/2+w(log n/ p n) (Blum, Burch, and Langford, FOCS’98). This is in contrast with the situation for nonmonotone functions, where a wide range of cryptographic hardness results establish that various “simple” classes of polynomial-size circuits are not learnable by polynomial-time algorithms.

Scalable Multi-Core Model Checking Fairness Enhanced Systems, Yang Liu, Jun Sun, Jin Song Dong

Research Collection School Of Computing and Information Systems

Rapid development in hardware industry has brought the prevalence of multi-core systems with shared-memory, which enabled the speedup of various tasks by using parallel algorithms. The Linear Temporal Logic (LTL) model checking problem is one of the difficult problems to be parallelized or scaled up to multi-core. In this work, we propose an on-the-fly parallel model checking algorithm based on the Tarjan’s strongly connected components (SCC) detection algorithm. The approach can be applied to general LTL model checking or with different fairness assumptions. Further, it is orthogonal to state space reduction techniques like partial order reduction. We enhance our PAT …

Progress Toward The Total Synthesis Of Lyconadin A, Yu Zhang

Theses and Dissertations

Lyconadin A is a pentacyclic Lycopodium alkaloid isolated from the club moss Lycopodium complanatum with antitumor properties. We have developed a novel 7-exo/6-exo acyl radical cascade cyclization as a method of making the bicyclo[5.4.0]undecane ring system of lyconadin A. The model products are trans-fused ring systems, while a cis-fused ring system is needed in lyconadin A. We have discovered a method to convert the trans-fused model cascade cyclization product into the desired cis isomer. Based on Donohoe's pyridone synthesis, we developed a method for the construction of 5-alkyl and 3,5-dialkyl-6-carbomethoxy-2-pyridones, the former of which …

Saving Energy In Network Hosts With An Application Layer Proxy: Design And Evaluation Of New Methods That Utilize Improved Bloom Filters, Miguel Jimeno

USF Tampa Graduate Theses and Dissertations

One of the most urgent challenges of the 21st century is to investigate new technologies that can enable a transition towards a society with a reduced CO₂ footprint. Information Technology generates about 2% of the global CO₂, which is comparable to the aviation industry. Being connected to the Internet requires active participation in responding to protocol messages. Billions of dollars worth of electricity every year are used to keep network hosts fully powered-on at all times only for the purpose of maintaining network presence. Most network hosts are idle most of the time, thus presenting a huge …

Uncertainty In Measurements And Cognitive Engineering Analysis Of A Decision Support System For Power System Reconfiguration, Venkata Krishna Pendurthi

Theses and Dissertations

Accuracy of the measurement data used for the decision making process or for shipboard operations and control is very important to ensure the reliability and survivability. The uncertainties present in measurement data need to be minimized for reliable system operation. In this work, a fuzzy logic based model is developed to deal with uncertainty in the meter data. Operational and historical parameters of the meters were used to determine a ‘trust’ value of individual meter. A fuzzy correction system for measurement data was used to generate an input dataset for a genetic algorithm based reconfiguration system. Additionally, with the goal …
