The Development Of A Hydrodynamics-Based Storm Severity Index, Gabriel Francis Todaro

UNF Graduate Theses and Dissertations

A hydrodynamic-based storm severity scale that ranks the damage potential of a storm at a given coastal area is developed. Seventeen tropical and extratropical storm events at 113 different locations on the Atlantic coast and the Gulf of Mexico are examined in order to create and verify a Storm Severity Index Model (SSIM). The results from the SSIM are then used to create a location-based storm severity scale titled the Twenty-Four Point Storm Severity Scale. The Twenty-Four Point Scale is based on three subsets of factors. The first is the energy flux above the normal mean high water line that …

Use Of Ibm Collaborative Lifecycle Management Solution To Demonstrate Traceability For Small, Real-World Software Development Project, Lovelesh Chawla

UNF Graduate Theses and Dissertations

The Standish Group Study of 1994 showed that 53 percent of software projects failed outright and another 31 percent were challenged by extreme budget and/or time overrun. Since then different responses to the high rate of software project failures have been proposed. SEI’s CMMI, the ISO’s 9001:2000 for software development, and the IEEE’s JSTD-016 are some examples of such responses. Traceability is the one common feature that these software development standards impose.

Over the last decade, software and system engineering communities have been researching subjects such as developing more sophisticated tooling, applying information retrieval techniques capable of semi-automating the trace …

Disruption Of Skin Stem Cell Homeostasis Following Transplacental Arsenicosis; Alleviation By Combined Intake Of Selenium And Curcumin, Shiv Poojan, Sushil Kumar, Vikas Verma, Anupam Dhasmana, Mohtashim Lohani, Mukesh K. Verma

School of Medicine Publications

Of late, a consirable interest has grown in literature on early development of arsenicosis and untimely death in humans after exposure to iAs in drinking water in utero or during the childhood. The mechanism of this kind of intrauterine arsenic poisoning is not known; however it is often suggested to involve stem cells. We looked into this possibility by investigating in mice the influence of chronic in utero exposure to arsenical drinking water preliminarily on multipotent adult stem cell and progenitor cell counts at the beginning of neonatal age. We found that repeated intake of 42.5 or 85ppm iAs in …

Stability Of A Circular System With Multiple Asymmetric Laplacians, Ivo Herman, Dan Martinec, J. J. P. Veerman, Michael Sebek

Mathematics and Statistics Faculty Publications and Presentations

We consider an asymptotic stability of a circular system where the coupling Laplacians are different for each state used for synchronization. It is shown that there must be a symmetric coupling in the output state to guarantee the stability for agents with two integrators in the open loop. Systems with agents having three or more integrators cannot be stabilized by any coupling. In addition, recent works in analysis of a scaling in vehicular platoons relate the asymptotic stability of a circular system to a string stability. Therefore, as confirmed by simulations in the paper, our results have an application also …

External piezoelectric actuation has been used to drive the devices into resonance while integrated piezoresistive transduction has been chosen as the resonance …

Prediction Of Load Capacity Variation In Frp Bonded Concrete Specimens Using Brownian Motion, Tayyebeh Mohammadi, Baolin Wan, Jian-Guo Dai, Chao Zhu

Civil and Environmental Engineering Faculty Research and Publications

In wet lay-up process, dry fiber sheets are saturated with a polymer and applied to the concrete surface by hand. This causes relatively large variation in properties of the cured FRP composite material. It is hard to know the exact mechanical properties of the FRP constructed by wet lay-up process. In addition, the stiffness of FRP changes during debonding process due to different amount of concrete attached to the debonded FRP at different locations. It is also inevitable to have considerable variations in the strength of concrete. Therefore, the behaviour of FRP bonded concrete members varies among specimens even when …

H.P. Lovecraft & The French Connection: Translation, Pulps And Literary History, Todd David Spaulding

Theses and Dissertations

Weird fiction writer H. P. Lovecraft captured the zeitgeist of the modernist movement, despite his association with popular fiction. Lovecraft’s post-mortem climb from the margins of the American literary system to its center is indicative of his influence on “mass” and “elite” cultures alike in the second half of the twentieth century and onward. Lovecraft’s influence is not restricted to American culture, but it spread like an airborne virus to other cultures, and to France in particular. His imaginative weird fiction, a unique combination of horror and science fiction, has been translated into more than 25 languages from Bengali to …

3-D Numerical Simulation Of Carbon Dioxide Injection Into The South Georgia Rift Basin For Geologic Storage, Daniel Eric Taylor Brantley

Theses and Dissertations

This study numerically simulated the injection of supercritical phase CO2 into the South Georgia Rift (SGR) basin to evaluate the feasibility and efficacy of long term geologic storage. The injection simulation modeling was divided into two phases. During phase one of the modeling, very little geologic and reservoir dynamics data was known about the SGR basin. Due to lack of basin data, an equilibrium model was used to estimate the initial hydrostatic pressure, temperature and salinity gradients that represent our study area. For the equilibrium model, the USGS SEAWAT program was used and for the CO2 injection simulation, TOUGH2-ECO2N was …

Influence Of High-Intensity Turbulence On Laminar Boundary Layer Development On A Cylindrical Leading Edge: Enhancement To Eddy Diffusivity, Juli Pearson

Theses and Dissertations

The growing demand for increased efficiency in turbine engine designs has sparked a growing interest for research of air flow around curved surfaces. The turbine’s operating conditions result in material property constraints, especially in the first stage turbine vanes and blades. These turbine vane components experience extreme loading conditions of both high temperature and high turbulence intensities exiting the combustor. The surface of the turbine blades has cylindrical leading edges that promote stabilizing flow accelerations. These convex surfaces can cause a reduced eddy diffusivity across the boundary layer.

This thesis reviews measurements of velocity and turbulence intensities taken just shy …

Modern unmanned aerial vehicles (UAV) are made of lightweight structures, owing to the demand for longer ranges and heavier payloads. These lightweight aircraft are more susceptible to vibrations caused by atmospheric turbulence transmitted to the fuselage from the wings. These vibrations, which can cause damage to the payload or on board avionics present a serious problem, since air turbulence is expected to increase over the next few decades, due to climate change.

The objective of this thesis is to predict the vibration of an aircraft fuselage by establishing a relationship between wing and fuselage vibration. A combination of ANSYS® and …

Preventing Or Mitigating The Irreversible Ro Membrane Fouling Caused By Dissolved Organic Matter And Colloidal Materials During Surface Water Treatment, Raphael Ade Afonja

Theses and Dissertations

Reverse osmosis (RO) is increasingly being used for water treatment because of its small ecological footprint and improved membrane technology. However, a major challenge to the application of this technology in water treatment is the irreversible fouling observed in RO membranes. Fouling, mainly caused by dissolved organic matter (DOM) and colloidal materials (CM) in water, can increase the energy and maintenance costs and decrease the permeation flux and membrane life. Different pretreatments, such as coagulation, flocculation, sedimentation, and membrane-filtration, need to be applied upstream of the RO system to remove potential RO foulants. Membrane remediation by chemical cleaning also needs …

Local Buckling Restraining Behavior Of Concrete-Filled Steel Tubular Columns Under Seismic Loads, Fokruddin Ahmad

Theses and Dissertations

Extensive investigations have verified that frame systems consist of concrete-filled steel tubular (CFST) columns have more benefits than ordinary reinforced concrete and steel systems. The CFST column increases earthquake resistant capabilities due to the concrete filling inside the steel tubes and are ideal for buildings subjected to large compressive stress. The use of CFST columns is drawing attention due to their strength and quake-proof advantages. Local buckling of the steel tube is delayed by the restraint of the concrete, and the strength of concrete is increased by the confining effect of the steel tube.

This thesis deals with the local …

Inquiry-Based Teaching In The College Classroom: The Nontraditional Student, Daniel A. Kiernan

Theses and Dissertations

Decline in the economic realm often bolsters an increase of nontraditional student enrollments in colleges and universities (Windolf, 1992). Many of these students, who do not desire to major in some scientific area, find themselves struggling in required science courses. Over the last decade, science departments of higher education have been adjusting their curriculum to include inquiry in the college science classroom. Although inquiry-based teaching has been shown to be very academically positive in science classrooms from K-12, “at the college level the data are mixed as to whether increasing inquiry instruction can significantly change students’ learning or attitudes toward …

An Investigation Of A Culturally Responsive Approach To Science Education In A Summer Program For Marginalized Youth, Brittany A. Garvin

Theses and Dissertations

The demographics of today’s schools are becoming more and more ethnically and linguistically diverse, as culturally diverse students comprise approximately one third of school populations (Ladson-Billings, 2005). However, the educational experiences of students of Color demonstrate a history of marginalization and inequity (Williamson et al., 2007) as far too many students of Color have maintained poor educational achievement outcomes. The effects of such disproportionally high levels of low academic achievement are extensive and can be witnessed across subject content areas, particularly in math, science, and literacy. To improve the academic performance of students who are culturally, racially, ethnically, and linguistically …

Investigating Flipped Learning: Post-Secondary Student Self-Regulated Learning, Perceptions, And Achievement, Sarah Rae Sletten

Theses and Dissertations

The flipped classroom is a current educational model that is gaining popularity at the post-secondary level. In a flipped classroom, content (i.e., lectures), which is normally delivered in-class, is assigned as homework in the form of video lectures, and assignments that were traditionally assigned as homework, are done as learning activities in class. It was hypothesized that the effectiveness of the flipped model hinges on a student’s desire and ability to adopt a self-directed learning style. The purpose of this study was two-fold; it aimed examining the relationship between two variables—students’ perceptions of the flipped model and their SRL behaviors—and …
