Effectiveness And Kinetics Of Ferrate As A Disinfectant For Ballast Water, Andrea L. Jessen
Electronic Theses and Dissertations
The introduction of aquatic nuisance species (ANS) and bacterial pathogens from discharge of ballast water by sea-faring vessels is an ongoing problem that threatens ecosystems and human health. This study investigates the disinfecting capability of ferrate in a marine environment on several organisms listed in international standards for ballast water management. Organisms were grown in a saline solution and were treated with dosages of ferrate ranging from 0.25-5.0 mg/l. A ferrate dose of 5 mg/l resulted in almost complete kill for all organisms tested. Smaller dosages have also been very effective, particularly if all organic material from the nutrient broth …
Developing Emergency Preparedness Plans For Orlando International Airport (Mco) Using Microscopic Simulator Watsim, Daniel Dawson
Developing Emergency Preparedness Plans For Orlando International Airport (Mco) Using Microscopic Simulator Watsim, Daniel Dawson
Electronic Theses and Dissertations
Emergency preparedness typically involves the preparation of detailed plans that can be implemented in response to a variety of possible emergencies or disruptions to the transportation system. One shortcoming of past response plans was that they were based on only rudimentary traffic analysis or in many cases none at all. With the advances in traffic simulation during the last decade, it is now possible to model many traffic problems, such as emergency management, signal control and testing of Intelligent Transportation System technologies. These problems are difficult to solve using the traditional tools, which are based on analytical methods. Therefore, emergency …
Multiple View Geometry For Video Analysis And Post-Production, Xiaochun Cao
Multiple View Geometry For Video Analysis And Post-Production, Xiaochun Cao
Electronic Theses and Dissertations
Multiple view geometry is the foundation of an important class of computer vision techniques for simultaneous recovery of camera motion and scene structure from a set of images. There are numerous important applications in this area. Examples include video post-production, scene reconstruction, registration, surveillance, tracking, and segmentation. In video post-production, which is the topic being addressed in this dissertation, computer analysis of the motion of the camera can replace the currently used manual methods for correctly aligning an artificially inserted object in a scene. However, existing single view methods typically require multiple vanishing points, and therefore would fail when only …

Sub-Pixel Registration In Computational Imaging And Applications To Enhancement Of Maxillofacial Ct Data, Murat Balci
Electronic Theses and Dissertations
In computational imaging, data acquired by sampling the same scene or object at different times or from different orientations result in images in different coordinate systems. Registration is a crucial step in order to be able to compare, integrate and fuse the data obtained from different measurements. Tomography is the method of imaging a single plane or slice of an object. A Computed Tomography (CT) scan, also known as a CAT scan (Computed Axial Tomography scan), is a Helical Tomography, which traditionally produces a 2D image of the structures in a thin section of the body. It uses X-ray, which …

Developing Microscopic Toll Plaza Model Using Paramics, Nezamuddin Nezamuddin
Electronic Theses and Dissertations
Simulation modeling is the most cost-effective way of studying real life transportation problems, either existing or anticipated, without disturbing the balance of the transportation system. There is a vast suite of simulation models available in market, ready to choose from macroscopic, mesoscopic, or microscopic in nature, to study different transportation system elements like freeways, highways, signalized and un-signalized intersections. However, most of these network simulation models, like PARAMICS, VISSIM, CORSIM etc, do not come readily available with built in toll plaza models. On the other hand, many researchers have independently developed toll plaza models, which can only model an isolated …
Influence Map Methodology For Evaluating Systemic Safety Issues, Timothy Barth
Influence Map Methodology For Evaluating Systemic Safety Issues, Timothy Barth
Electronic Theses and Dissertations
Raising the bar in safety performance is a critical challenge for many organizations. Contributing factor taxonomies organize information on why accidents occur. Therefore, they are essential elements of accident investigations and safety reporting systems. Organizations must balance efforts to identify causes of specific accidents with efforts to evaluate systemic safety issues in order to become more proactive about improving safety. This research successfully addressed two problems: (1) limited methods and metrics exist to support the design of effective taxonomies, and (2) influence relationships between contributing factors are not explicitly modeled within a taxonomy. The primary result of the taxonomic relationship …
The Effectiveness Of A Specifically Designed Green Roof Stormwater Treatment System Irrigated With Recycled Stormwater Runoff To Achieve Pollutant Removal And Stormwater Volume Reduction, Michael Hardin
Electronic Theses and Dissertations
One of our greatest threats to surface-water quality is polluted stormwater runoff. In this research, investigated is the use of a green roof irrigated with recycled stormwater runoff to remove pollutants from stormwater runoff and reduce the volume of stormwater runoff leaving developed areas. The green roof properties of interest are the filtration and biological processes as well as the roof's ability to hold water and increase evapotranspiration, reducing the volume of stormwater runoff from the source. Because of the above mentioned reasons the experiment consists of a water quality analysis and a water budget done on several experimental chambers …
Iterchanging Discrete Event Simulationprocess Interaction Modelsusing The Web Ontology Language - Owl, Lee Lacy
Electronic Theses and Dissertations
Discrete event simulation development requires significant investments in time and resources. Descriptions of discrete event simulation models are associated with world views, including the process interaction orientation. Historically, these models have been encoded using high-level programming languages or special purpose, typically vendor-specific, simulation languages. These approaches complicate simulation model reuse and interchange. The current document-centric World Wide Web is evolving into a Semantic Web that communicates information using ontologies. The Web Ontology Language OWL, was used to encode a Process Interaction Modeling Ontology for Discrete Event Simulations (PIMODES). The PIMODES ontology was developed using ontology engineering processes. Software was …
Epidemiological Models For Mutating Pathogens With Temporary Immunity, Neeta Singh
Epidemiological Models For Mutating Pathogens With Temporary Immunity, Neeta Singh
Electronic Theses and Dissertations
Significant progress has been made in understanding different scenarios for disease transmissions and behavior of epidemics in recent years. A considerable amount of work has been done in modeling the dynamics of diseases by systems of ordinary differential equations. But there are very few mathematical models that deal with the genetic mutations of a pathogen. In-fact, not much has been done to model the dynamics of mutations of pathogen explaining its effort to escape the host's immune defense system after it has infected the host. In this dissertation we develop an SIR model with variable infection age for the transmission …
Investigating The Effectiveness Of Redundant Text And Animation In Multimedia Learning Environments, Shiau-Lung Chu
Investigating The Effectiveness Of Redundant Text And Animation In Multimedia Learning Environments, Shiau-Lung Chu
Electronic Theses and Dissertations
In multimedia learning environments, research suggests that simultaneous presentation of redundant text (i.e. identical narration and on-screen text) may inhibit learning when presented with animation at the same time. However, related studies are limited to testing with cause-and-effects content information (e.g., Moreno & Mayer, 1999, 2002). This study examined the effects of redundant text on learners' memory achievement and problem solving ability. The study replicated and extended prior research by using descriptive, rather than cause-and-effect content information. The primary research questions were (a) does redundant text improve learning performance if learners are presented with instructional material that addresses subject matter …

An Investigation Of Altruism And Personality Variables Amongbeginning Counseling Students, Laura Schmuldt
An Investigation Of Altruism And Personality Variables Amongbeginning Counseling Students, Laura Schmuldt
Electronic Theses and Dissertations
Altruism is loosely defined as a desire to help others as well as acts and behaviors towards that end, particularly when no expectation of personal gain or reward exists (Batson, Fultz, Schoenrade & Paduano, 1987). It seems likely that individuals who choose to pursue acareer in counseling might be doing so out of some altruistic interest; in other words a desire to come to the aid of others in distress. It has been noted as well that some individuals may enter the counseling profession based more on self-interest; for example, as "wounded healers" hoping to work on personal issues (Wheeler, …

Electronic Theses and Dissertations
Do you remember the first time you used an Automatic Teller Machine (ATM)? Or a pay-at-the-pump gas station? Or an airline e-ticket kiosk? How did you know what to do? Although you never received any formal instruction in how to interact with the self-service technology, you were likely able to accomplish your task (e.g., withdrawing or depositing money) as successfully as an experienced user. However, not so long ago, to accomplish that same task, you needed the direct mediation of a service professional who had been trained how to use the required complex technology. What has changed? In short, the …

Predicting Surface Scatter Using A Linear Systems Formulation Of Non-Paraxial Scalar Diffraction, Andrey Krywonos
Predicting Surface Scatter Using A Linear Systems Formulation Of Non-Paraxial Scalar Diffraction, Andrey Krywonos
Electronic Theses and Dissertations
Scattering effects from rough surfaces are non-paraxial diffraction phenomena resulting from random phase variations in the reflected wavefront. The ability to predict these effects is important in a variety of applications including x-ray and EUV imaging, the design of stray light rejection systems, and reflection modeling for rendering realistic scenes and animations of physical objects in computer graphics. Rayleigh-Rice (small perturbation method) and Beckmann-Kirchoff (Kirchhoff approximation) theories are commonly used to predict surface scatter effects. In addition, Harvey and Shack developed a linear systems formulation of surface scatter phenomena in which the scattering behavior is characterized by a surface transfer …

Tya Methodology Twentieth-Century Philosophy, And Twenty-First Century Practice: An Examination Of Acting, Directing, And Dramatic Literature, Allen Mccoy
Electronic Theses and Dissertations
Throughout the twentieth century, theatre for young audiences (TYA), or children's theatre, has been situated as something "other" or different than adult theatre, a kind of theatre--but not really theatre, a construct which opened the door to numerous "how to" philosophies geared specifically toward the theatre for young audiences practitioner. As a twenty-first century theatre practitioner, I am interested in how these philosophies are situated within or against current professional practices in the TYA field. This interest led me to the main question of this study: What are the predominant twentieth-century philosophies on acting, directing, and dramatic literature in the …
Between Continents, Mona Hassan
Between Continents, Mona Hassan
Electronic Theses and Dissertations
Between Continents is a collection of thirty-two poems. The most challenging aspect of finding the right voice and the appropriate metaphors in "Between Continents" has been the difficulty in assimilating a diversity of traditions within my own work. The polarity of aesthetic values is a well known feature of contemporary American poetry. Charles Webb in his essay on the competing aesthetics in poetry uses the metaphor of apples and orangutans to point out how exaggerated this difference really is. Jorie Graham sees in the way young writers today are simultaneously influenced by elements of poets whose philosophies mutually exclude each …
