Rainfall-Runoff Modeling In Humid Shallow Water Table Environments, Tatiana X. Hernandez

USF Tampa Graduate Theses and Dissertations

Simulating the processes of rainfall and runoff are at the core of hydrologic modeling. Geomorphologic features, rainfall variability, soil types, and water table depths strongly influence hydrological process in Florida ecosystems. Topographic characteristics of the terrain define the stream paths and landscape. Alteration of these characteristics as a result of urban and/or agricultural developments, for example, can highly influence wetlands and river basin response. There are two predominant landforms in Florida: wetlands, where Variable Saturated Areas form near streams causing saturation excess runoff, and uplands where runoff is mainly generated by infiltration excess.

Difference In Hearing Screening Failure Rates As A Function Of Ethnicity In Well Newborns Screened At Tampa General Hospital, Sybil N. Prewitt

USF Tampa Graduate Theses and Dissertations

The difference in otoacoustic emission (OAE) hearing screening failure rates as a function of ethnic category was investigated in a population of newborns at Tampa General Hospital, Tampa, Florida. Clinical observation led to a concern that due to a higher incidence of outer and middle ear dysfunction in Hispanic newborns and children, screening could result in disparate failure rates, with a larger number of these infants requiring further testing. This result would warrant changes in current protocols, as well as screener training,and parent counseling practices.

Between January and July of 2000, 1407 newborns were tested utilizing distortion product otoacoustic emission …

Literacy, Technology, And Change: The Gates Of Hell, Janice R. Walker

USF Tampa Graduate Theses and Dissertations

In this dissertation, I first briefly examine the history of technology as it impacts on literacy practices, and especially the history of resistance to technological developments in the humanities. In so doing, I also briefly examine some of the possible ideological underpinnings of this resistance, including looking at some of the arguments proposed to counter it. More specifically, I consider how literacy practices, pedagogical practices, and assessment and gatekeeping practices in the field of composition studies impact on and are impacted by the intersection of computer technologies and our field. Finally, I offer some suggestions for ways in which our …

Knowledge-Guided Processing Of Magnetic Resonance Images Of The Brain, Matthew C. Clark

USF Tampa Graduate Theses and Dissertations

This dissertation presents a knowledge-guided expert system that is capable of applying routinesfor multispectral analysis, (un)supervised clustering, and basic image processing to automatically detect and segment brain tissue abnormalities, and then label glioblastoma-multiforme brain tumors in magnetic resonance volumes of the human brain. The magnetic resonance images used here consist of three feature images (T1-weighted, proton density, T2-weighted) and the system is designed to be independent of a particular scanning protocol. Separate, but contiguous 2D slices in the transaxial plane form a brain volume. This allows complete tumor volumes to be measured and if repeat scans are taken over time, …

Stratigraphy And Geologic History, Bunces Key, Pinellas County, Florida, Douglas E. Crowe

USF Tampa Graduate Theses and Dissertations

Bunces Key, a narrow, linear, barrier island on the west-central coast of Florida, was founded in 1961. Its growth and development since that time is well documented by aerial photography. Cores taken from the Key and surrounding areas reveal a stratigraphic succession of facies reflecting rapid vertical aggradation. Sedimentation began on a gently sloping platform through the landward migration of large scale bedforms (sand waves) during fair weather periods. Migration of these bedforms ceased when emergence and lack of continued overwash precluded further movement. Vertical accretion to supratidal levels resulted from the continued onshore transport of sediment and subsequent welding …
