Examination Of The R-Process In Accretion-Induced Collapse (Aic), Daryl C. Davis Jan 2005

Examination Of The R-Process In Accretion-Induced Collapse (Aic), Daryl C. Davis

Electronic Theses and Dissertations 2000 - 2009

This work is a simulation of the Accretion-Induced Collapse of a 1.37 solar mass white dwarf into a neutron star and the subsequent generation of a neutrino-driven wind, with an examination as to whether the event is a candidate for r-process nucleosynthesis. The simulation utilizes a new radiation hydrodynamic code, RadHyd, to model the AIC event. We examine the process of Accretion-Induced Collapse utilizing two sets of neutrino-scattering and absorption rates: The first, and simpler of the two has been in use since they were first introduced in 1985. The second includes a more accurate implementation of neutrino-nucleon scattering and …

Experimental Study Of The Wake-Modes For Propulsion Of Two-Dimensional Heaving Airfoils, Alan Joe Buzard Jan 2005

Experimental Study Of The Wake-Modes For Propulsion Of Two-Dimensional Heaving Airfoils, Alan Joe Buzard

Electronic Theses and Dissertations 2000 - 2009

Particle image velocimetry and flow visualization are used to characterize the wake of a heaving airfoil in a set of two experiments. In the first experiment a tandem airfoil configuration is used, with a stationary airfoil downstream of a heaving airfoil (modified Schmidt wave-propeller). Several vortex structures are identified for a forced Strouhal number (St)---based on airfoil chord-length, forcing frequency, and free-steam velocity---for 0.1 < St < 0.7. An asymmetric average velocity profile is measured in the upper St range. In the second experiment, the wake behind a single heaving airfoil is further inspected, with the purpose of highlighting the asymmetric wake, for 0.1 < St < 1.0. A maximum wake excursion of 18 degrees is measured at St = 0.6, and a minimum excursion of 5.7 degrees occurs at St = 0.9. Using averaged velocity profiles, a virtual origin of the wake excursion is also calculated.

Evolutionary Psychological Approach To The Study Of Sibling Influences, Richard L. Michalski Jan 2005

Evolutionary Psychological Approach To The Study Of Sibling Influences, Richard L. Michalski

Electronic Theses and Dissertations 2000 - 2009

Research in the psychological sciences has long focused on the impact families have on later development. One feature of families is the birth order in which children from one family develop. Birth order serves as a proxy for developmentally relevant criteria including differences in age, size, and status between siblings. Following from theories derived from evolutionary psychology, differences in perceived favoritism, personality dimensions, and sexual strategy are examined. As an initial examination of the influences siblings can have beyond childhood, responses to the upset over the infidelities of in-laws are examined. Results from this series of studies suggests (1) birth …

Estimation Of The Scattering Function Of Fading Channels For Acoustic Communications In Shallow Waters, Vincent. Allemand Jan 2005

Estimation Of The Scattering Function Of Fading Channels For Acoustic Communications In Shallow Waters, Vincent. Allemand

Electronic Theses and Dissertations 2000 - 2009

The measurement of the Scattering function of time-variant fading channels is of strong interest in the field of underwater acoustic communications, as it indicates the limitations of the channel capacity. It also helps reducing the development time of acoustic communication systems and the need for on-site tests using so-called "fading simulators". The Scattering function is interpreted as the expected power received at a given time-delay and frequency shift for a given signal transmitted through the acoustic channel. It has been estimated using a fourth-moment method developed by Kailath from 18 to 30 kHz, 8-ms broad-band chirps and 20--28 kHz, 28-ms …

Fashion And Power: The Representation Of Gender In Store Window Displays, Kami T. Barrett Jan 2005

Fashion And Power: The Representation Of Gender In Store Window Displays, Kami T. Barrett

Electronic Theses and Dissertations 2000 - 2009

Fashion and dress have a complex relationship to identity. The clothes we choose to wear can express our identities in terms of gender, race, class, and/or sexuality, among other things. This study examines how gender, race, and class are used to interpellate primarily female shoppers through store window advertising in the city of London, England. Using a feminist cultural and media studies approach, I analyze eight store window display advertisements as texts, and how their portrayals of women are presented to consumers. This study concludes that stereotypical, degrading, humiliating and violating representations of women and femininity abound in store window …

Four Hostile Newspapers: The Role Of Bal Gangadhar Tilak And Arthur Griffith In Constructing A National Identity In India And Ireland, Susan A. Rosenkranz Jan 2005

Four Hostile Newspapers: The Role Of Bal Gangadhar Tilak And Arthur Griffith In Constructing A National Identity In India And Ireland, Susan A. Rosenkranz

Electronic Theses and Dissertations 2000 - 2009

Although historians have begun to explore the impact of Irish nationalism on India's nationalists in the late nineteenth and early twentieth century, few studies have examined the link between Irish and Indian journalism in that same era. While the Indian National Congress and the Irish Parliamentary Party pursued constitutional means to achieve Home Rule, their elitist composition ensured that neither enjoyed broad appeal. Thus, the emergence of a viable native press played a critical role in the forging of a national identity. In the vanguard of the movement were editors Bal Gangadhar Tilak and Arthur Griffith, whose newspapers provided a …

Gopher Tortoise Habitat Use And Spatial Distribution In A Southeastern Florida Population, E. H. King Jan 2005

Gopher Tortoise Habitat Use And Spatial Distribution In A Southeastern Florida Population, E. H. King

Electronic Theses and Dissertations 2000 - 2009

Gopher tortoise ecology is poorly understood in the rapidly developing, urbanized southeastern end of its range. This study reports on a population at Florida Atlantic University in Boca Raton, Florida. Burrow surveys were conducted from May to July 2003 and May to August 2004. Burrows were marked and mapped as was vegetative cover. Burrow locations were tested against vegetative cover height and soil types. Burrow locations did not differ among soil types. The densest concentrations of burrows were located in areas of low, patchy vegetative cover. This is consistent with known gopher tortoise habitat preferences elsewhere in their range. Gopher …

Hot Pink, Lee E. Pifer Jan 2005

Hot Pink, Lee E. Pifer

Electronic Theses and Dissertations 2000 - 2009

The poems of this thesis take the reader to primal places of the mind, body, and soul, often considered better left unspoken or unseen. These places are no doubt dark and full of strange dreams. Here, relationships have a lack of resolution and, of course, are engineered by pleasure and pain. Pain is fire, ice, or reflection. Pleasure is also pain. It is all an eternal dance. Pain gives pleasure meaning and vice versa, like violence and passion. There is a pleasure in the heat rising from a red bottom, and a beauty in that image. I challenge social customs …

Human Mate Poaching: How Frequent Is It And What Motivates It?, Alastair P C Davies Jan 2005

Human Mate Poaching: How Frequent Is It And What Motivates It?, Alastair P C Davies

Electronic Theses and Dissertations 2000 - 2009

Mate poaching occurs when an individual has sexual relations with the romantic partner of another. In Study A, I investigated the prevalence of mate poaching by presenting participants with questions whose devising was informed by a stricter definition of mate poaching than that employed by earlier studies. As expected, relative to participants in earlier studies, the current participants reported fewer experiences of mate poaching. In Study B, I investigated the likelihood that the benefits and costs of mate poaching will, respectively, motivate participants to poach or will deter them from doing so. Results indicated that for males and females to …

Impact Of The Red Imported Fire Ant (Solenopsis Invicta ) On Two Species Of Sea Turtle Hatchlings, Holly B. Krahe

Electronic Theses and Dissertations 2000 - 2009

Although the red imported fire ant (Solenopsis invicta ) is known to kill sea turtle hatchlings, little research has focused on sub-lethal effects of ant attacks on hatchlings emerging from nests. Sea turtle hatchlings of two species (Caretta caretta and Chelonia mydas) exposed to fire ants during incubation and emergence were collected on Juno Beach, Florida. Hatchlings were maintained for ten days in a common saltwater outdoor pool at the Marinelife Center, Juno Beach. Hatchlings showing pustules diagnostic of S. invicta stings were compared to non-stung controls in terms of survival, growth (mass and SCL) and initial crawling strength. Loggerhead …

Influence Of Eliot's Modernism In Two Early Novels And Autobiographies Of Doris Lessing, M. Catherine Burns Jan 2005

Influence Of Eliot's Modernism In Two Early Novels And Autobiographies Of Doris Lessing, M. Catherine Burns

Electronic Theses and Dissertations 2000 - 2009

There is deep personal and artistic empathy for T. S. Eliot's modernist poetry in Doris Lessing's early novels and two later autobiographies. As Eliot did, Lessing uses the modernist doctrine of difficulty to portray the education and development of the writer-artist as a long, problematic process, involving prodigious, rigorous, energetic reading efforts, and self-conscious reflexive writing. Lessing also frequently quotes other authors, and she thoroughly uses subverted allusive schemes and extrusive structural complications to render realism in her narratives more vividly. Her mature aesthetic sets at a distance a sense of personal displacement, exile, and uncertain cultural identity and echoes …

Intrusion Detection In Wireless Networks: A Data Mining Approach, Shyam Varan Nath Jan 2005

Intrusion Detection In Wireless Networks: A Data Mining Approach, Shyam Varan Nath

Electronic Theses and Dissertations 2000 - 2009

The security of wireless networks has gained considerable importance due to the rapid proliferation of wireless communications. While computer network heuristics and rules are being used to control and monitor the security of Wireless Local Area Networks (WLANs), mining and learning behaviors of network users can provide a deeper level of security analysis. The objective and contribution of this thesis is three fold: exploring the security vulnerabilities of the IEEE 802.11 standard for wireless networks; extracting features or metrics, from a security point of view, for modeling network traffic in a WLAN; and proposing a data mining-based approach to intrusion …

Investigation Of The Influence Of Surface Roughness On Reflection Coefficients Measured By A Chirp Sonar Using A Laser Profiling Of The Seafloor, Nicolas. Hache Jan 2005

Investigation Of The Influence Of Surface Roughness On Reflection Coefficients Measured By A Chirp Sonar Using A Laser Profiling Of The Seafloor, Nicolas. Hache

Electronic Theses and Dissertations 2000 - 2009

This research investigates the validity of an acoustic propagation model by comparing theoretical reflection coefficients, function of frequency, to FAU chirp sonar measurements (chirp sub-bottom profiler). An acoustic model has been implemented to estimate the spectrum of energy reflected from sandy sediments in the presence of surface scattering. The surface roughness being the dominant reverberation part, the volume scattering has been neglected in this model. A laser scanning system involving an image-processing algorithm has been designed to measure the seafloor bottom roughness using 1D Fourier transforms. In the case of anisotropic roughness, an estimation of the sand ripples dominant direction …

Textual Masks Of Nathanael West, Jared Bezet Jan 2005

Textual Masks Of Nathanael West, Jared Bezet

Electronic Theses and Dissertations 2000 - 2009

The novels of Nathanael West are preoccupied with the deconstruction of Western civilization, satirizing and parodying its most respected ideologies and literatures; they are also involved in recreating both cultural and personal identity from the deconstructed fragments of this culture by performances or masks of identity. The textual mask is a trope that performs both these functions in the work of Eliot, Pound, and Joyce, but especially in West. West demonstrated the mask's destructive force and constructive potential in both his writing and his personal life. The novels---The Dream Life of Balso Snell, Miss Lonelyhearts, A Cool Million, and The …

Study On Glucose Metabolism: Computer Simulation And Modeling, Meta. Leesirikul Jan 2005

Study On Glucose Metabolism: Computer Simulation And Modeling, Meta. Leesirikul

Electronic Theses and Dissertations 2000 - 2009

Sorensen's model of glucose metabolism and regulation is reconstructed using SimulinkRTM. Most of the existing glucose metabolism models consist of several mass balance equations that interact with each others. Graphical format used by SimulinkRTM provides a visualized perspective of such relations so that it is easier to modify the model on ad hoc basis. Type-I and Type-II diabetes with relevant clinical details are simulated. Further, a control strategy is introduced in order to simulate the control of exogenous insulin pump. Simulated results are consistent with available clinical data. Living systems in general, exhibit both stochastical and deterministic characteristics. Activities such …

Teacher Perspectives On The Effect Of The Florida Public Accountability System On The Middle School Classroom, Helen Roberts Jan 2005

Teacher Perspectives On The Effect Of The Florida Public Accountability System On The Middle School Classroom, Helen Roberts

Electronic Theses and Dissertations 2000 - 2009

The Florida Public Accountability System and the Florida Comprehensive Assessment Test, FCAT, have been in use since 1996. Since that time, schools have received grades, rewards and sanctions for performance, promotion requirements have changed, and the results of the FCAT are published annually for public scrutiny. With testing required in grades 3 through 11, middle schools (grades 6--8) must test all the students in their schools. A literature review revealed that, although achievement studies, drop out studies, and other data had been analyzed, little research focused on the impact of the FCAT from the perspective of the classroom teacher. This …

Theoretical And Experimental Studies Of Multisensory Integration As A Coupled Dynamical System, Collins G. Assisi Jan 2005

Theoretical And Experimental Studies Of Multisensory Integration As A Coupled Dynamical System, Collins G. Assisi

Electronic Theses and Dissertations 2000 - 2009

Perception and behavior are mediated by a widely distributed network of brain areas. Our main concern is, how do the components of the network interact in order to give us a variety of complex coordinated behavior? We first define the nodes of the network, termed functional units, as a strongly coupled ensemble of non-identical neurons and demonstrate that the dynamics of such an ensemble may be approximated by a low dimensional set of equations. The dynamics is studied in two different contexts, sensorimotor coordination and multisensory integration. First, we treat movement coupled to the environment as a driven functional unit. …

Un-Resistive Reproduction? Medical Hegemony, Pregnancy, And Reality Television, Serena R. Bruno

Electronic Theses and Dissertations 2000 - 2009

A new trend of unscripted, reality television programming chronicling the real-life childbirth experiences of American women and families has gained considerable ground in recent years. These programs, especially Discovery Health's BirthDay and The Learning Channel's A Baby Story, record, edit and broadcast the prenatal, childbirth, and postnatal health care of "everyday" women volunteers, including their physical, social, and emotional concerns. This research study focuses attention on the authoritative, technological and therefore, medically hegemonic perspective of this type of programming, illuminating through content, textual, focus group, and survey analyses the abundance of medically hegemonic meanings in both the discursive and visual …

When We Hurt The Ones We Love: Predicting Violence Against Women From Men's Mate-Retention Behaviors, Aaron T. Goetz Jan 2005

When We Hurt The Ones We Love: Predicting Violence Against Women From Men's Mate-Retention Behaviors, Aaron T. Goetz

Electronic Theses and Dissertations 2000 - 2009

Mate-retention behaviors are designed to solve several adaptive problems, such as deterring a partner's infidelity and preventing defection from the relationship. Although many mate-retention behaviors appear to be innocuous romantic gestures (e.g., giving flowers), some may be harbingers of violence. Here, the relationship between men's mate-retention and violence against women was investigated. In Study 1, men reported their use of mate-retention behaviors and violence in their relationships. Study 2 assessed women's reports of their partners' mate-retention behaviors and their partners' violence against them. Study 3 secured husbands' reports of their mate retention and wives' reports of their husbands' violence. As …

Validating The Search, Experience, And Credence Product Classification Framework In A Model Of Patronage Intentions, Tulay. Girard

Electronic Theses and Dissertations 2000 - 2009

Although the Internet as a shopping medium provides convenience to easily access products, the U.S. e-commerce retail sales still make up a very small percentage of the U.S. total retail sales. To better understand what influences consumers' choices to shop for products or services on the Internet versus local retail stores, this study tests the influence of antecedent factors of consumer patronage intentions for Internet and local retail stores. The study draws the antecedent factors from the extant literature, which include product classes, the importance consumers place on retailer attributes, and consumer perceived risk in product classes. Because the Internet …
