Dynamic Speed Monitoring System Effectiveness On Sharp Curves, Vasu Tavasna Persaud Jan 2007

Dynamic Speed Monitoring System Effectiveness On Sharp Curves, Vasu Tavasna Persaud

Electronic Theses and Dissertations

The design of rural interchanges is of critical concern due to the need for the safe transition of vehicles from one high speed roadways to another and vice versa. This transition is accomplished by entry and exit ramps of various forms. The southbound entry loop ramp at the US 27/ US 192 trumpet interchange in Polk County, Florida does not provide such safe transition since historically there has been a high incidence of vehicular off-tracking. The geometry of the southbound entry ramp coupled with high approach speeds are two of the contributing factors. Due to the high cost of interchange …

Optimizing The Design Of Multimodal User Interfaces, Leah Reeves Jan 2007

Optimizing The Design Of Multimodal User Interfaces, Leah Reeves

Electronic Theses and Dissertations

Due to a current lack of principle-driven multimodal user interface design guidelines, designers may encounter difficulties when choosing the most appropriate display modality for given users or specific tasks (e.g., verbal versus spatial tasks). The development of multimodal display guidelines from both a user and task domain perspective is thus critical to the achievement of successful human-system interaction. Specifically, there is a need to determine how to design task information presentation (e.g., via which modalities) to capitalize on an individual operator's information processing capabilities and the inherent efficiencies associated with redundant sensory information, thereby alleviating information overload. The present effort …

Stabel Isotope Turnover Rates And Diet-Tissue Discrimination In The Skin Of West Indian Manatees: Implcations For Evaluating Their Feeding Ecology And Habitat Use, Christy Alves

Electronic Theses and Dissertations

The West Indian manatee (Trichechus manatus) is an herbivorous marine mammal that occupies freshwater, estuarine, and marine habitats. Despite being considered endangered, relatively little is known about the feeding ecology of either of the two recognized subspecies, the Florida manatee (T.m. latirostris) and Caribbean or Antillean manatee (T.m. manatus). A better understanding of their respective feeding preferences and habitat use is essential to establish criteria on which conservation plans can be based. The present study expands on previous work on manatee feeding ecology by both assessing the application of stable isotope analysis to manatee tissue and providing critical baseline parameters …

Restoration Of Intertidal Oyster Reefs Affected By Intense Recreational Boating Activity In Mosquito Lagoon, Florida, Andrea Barber Jan 2007

Restoration Of Intertidal Oyster Reefs Affected By Intense Recreational Boating Activity In Mosquito Lagoon, Florida, Andrea Barber

Electronic Theses and Dissertations

In recent years, intertidal reefs of Crassostrea virginica (eastern oyster) along central Florida's east coast have suffered extensive losses due to wakes from recreational boats. These wakes have caused extensive shell movement and sediment resuspension which results in large piles of disarticulated shells along the seaward edges of reefs. Dead margins extend up to one meter above mean high water. The creation and enforcement of "no wake" zones in the area are unlikely. Thus, there is an urgent need for an alternative restoration strategy before these oyster reefs decline any further. The goal of this project was to develop a …

African Religious Integration In Florida During The First Spanish Period, Christopher Beats Jan 2007

African Religious Integration In Florida During The First Spanish Period, Christopher Beats

Electronic Theses and Dissertations

This thesis is an examination of the unique conditions for African-descended slaves in St. Augustine, Florida, during the First Spanish Period. St. Augustine was an important garrison at a remote point in the Spanish Empire at the edge of a hostile frontier. As such, economics were less a priority than defense. Slaves, therefore, received different treatment here than in English colonies or even other Spanish colonies. Due to the threat of Protestantism, religious adherence was more important as a test of loyalty than ethnicity and slaves and freed-people were able to integrate better than in other Spanish holdings. In order …

Genetic And Phenotypic Evolution In The Ornate Chorus Frog (Pseudacris Ornata): Testing The Relative Roles Of Natural Selection,, Jacob Degner Jan 2007

Genetic And Phenotypic Evolution In The Ornate Chorus Frog (Pseudacris Ornata): Testing The Relative Roles Of Natural Selection,, Jacob Degner

Electronic Theses and Dissertations

Understanding how migration, genetic drift, and natural selection interact to maintain the genetic and phenotypic variation we observe in natural populations is a central goal of population genetics. Amphibians provide excellent model organisms for investigating the interplay between these evolutionary forces because amphibians are generally characterized by limited dispersal abilities, high philopatry, and are obligately associated with the areas around suitable habitats (e.g. breeding ponds). Thus, on relatively small geographic scales, the relative effects of all of these evolutionary forces can be studied together. Here, we study the interaction of migration, genetic drift, natural selection, and historical process in the …

The Emergence Of The Maya Tlaloc: A Late Classic Religious Icon, Amanda Toyie Groff Jan 2007

The Emergence Of The Maya Tlaloc: A Late Classic Religious Icon, Amanda Toyie Groff

Electronic Theses and Dissertations

Iconography has the capability to memorialize and guarantee one's place in history; iconography can also provide powerful insight into human culture, and explore social and cultural values in a visual manner. Iconography can incorporate information about group identities, allegiances, religious affiliations, propaganda, and acceptance within both modern and ancient societies. By studying a specific iconographic figure, the Central Mexican god Tlaloc, as a visual representation of a belief or identity, we can glean a greater understanding of the cultural transmission of iconographic symbols. The substantial use of this icon, in both Central Mexico and the Maya region, reveals iconography as …

Demographic Consequences Of Managing For Florida Scrub-Jays (Aphelocoma Coerulescens) On An Isolated Preserve., Casey Lyon Jan 2007

Demographic Consequences Of Managing For Florida Scrub-Jays (Aphelocoma Coerulescens) On An Isolated Preserve., Casey Lyon

Electronic Theses and Dissertations

Many species naturally occupy discrete habitat patches within a mosaic of habitats that vary in quality. The Florida scrub-jay (Aphelocoma coerulescens) is endemic to Florida scrub, a habitat that is naturally patchy and greatly reduced in area over recent decades owing to development and urbanization. Because of this habitat loss, future management of Florida scrub-jays will focus on smaller, fragmented tracts of land. My study examines such a tract, Lyonia Preserve, southwest Volusia County, FL. This preserve was unoccupied by scrub-jays prior to habitat restoration. The preserve is now frequently managed exclusively for scrub-jays as a habitat island surrounded by …

Real-Time Tree Simulation Using Verlet Integration, Bobak Manavi Jan 2007

Real-Time Tree Simulation Using Verlet Integration, Bobak Manavi

Electronic Theses and Dissertations

One of the most important challenges in real-time simulation of large trees and vegetation is the vast number of calculations required to simulate the interactions between all the branches in the tree when external forces are applied to it. This paper will propose the use of algorithms employed by applications like cloth and soft body simulations, where objects can be represented by a finite system of particles connected via spring-like constraints, for the structural representation and manipulation of trees in real-time. We will then derive and show the use of Verlet integration and the constraint configuration used for simulating trees …

Responses Of Small Rodents To Restoration And Management Techniques Of Florida Scrub At Cape Canaveral Air Force Station, Florid, Alexis Suazo

Electronic Theses and Dissertations

Proper habitat management is essential for the survival and reproduction of species, especially those listed under state or federal laws as endangered, threatened or of special concern, and those with small local populations. Land managers use a combination of mechanical cutting and prescribed burning to manage and restore degraded scrub habitat in east central Florida. This approach improves habitat for the endangered Florida scrub-jay (Aphelocoma coerulescens), but little is known about its effects on other taxa, especially the threatened southeastern beach mouse (Peromyscus polionotus niveiventris). This single species approach may not be beneficial to other taxa, and mechanical cutting and …
