Replacement Prioritization Of Precast Deck Panel Bridges In Florida, Ganesh Deshmukh

USF Tampa Graduate Theses and Dissertations

During the mid 70's and early 80's, several precast deck panel bridges were constructed in Florida. These utilize prestressed precast panels as stay-in-place forms and are designed to act compositely with a cast-in-place deck which is poured subsequently. Such bridges offer advantages of quicker construction and lower costs. However, several such bridges built in Florida developed extensive cracking and spalling. Following localized failures, the Florida Department of Transportation have decided to replace all 127 precast panel deck bridges in Districts 1 and 7. Since deck replacement is contingent on funding, it is necessary to develop a rational procedure to decide …

Georeferencing Digital Camera Images Using Internal Camera Model, Alok Nagdev

USF Tampa Graduate Theses and Dissertations

The NASA Airborne Topographic Mapper (ATM) is a laser scanning instrument which is used mainly to collect dense topographic data over much of the conterminous US coastline. The inclusion of two digital cameras in consonance with the ATM instrument now gives 3-band (RGB) imagery apart from a very rich topographic data. This imagery, in its crude form, has limited applications due to it being not georeferenced and having a heavy camera lens distortions. As thesis, a processing system - Park-View - is developed to bring this imagery into a more suitable format for the scientists for analytical and interpretational purposes. …

She Fell To Her Knees And Other Stories, Karen Brown Gonzalez

USF Tampa Graduate Theses and Dissertations

These collected stories represent a culling from a portion of work that shares a similar theme of loss--its manifestation, its channeling, by various fictional characters, into the palpable and sensate, into the physical world of the body. They are people, mostly women, who have lost their hold on the world to which they are accustomed, who become entangled in situations where their bearings are skewed, their judgment faulty, their decisions based solely on a physical, most often sexual, attraction that simultaneously depletes a sense of worth, while providing its semblance.

The loss stems, at times, as in "Manifold," from beyond …

A Comparison Of Tone Burst Auditory Brainstem Response (Abr) Latencies Elicited With And Without Notched Noise Masking, Rachele M. Orsini

USF Tampa Graduate Theses and Dissertations

Objective: The air conduction click is currently the most widespread stimulus used to estimate the pure tone audiogram as part of auditory brainstem response (ABR) testing. The click is characterized by its broad spectral content and rapid onset, which may not make it the best choice for frequency specificity. An alternative stimulus is a short duration tone burst stimuli with notched noise masking. When obtaining an ABR using standard unmasked tone bursts, the brief stimulus onset may cause spectral splatter producing response contributions from unwanted regions of the cochlea; thus reducing the frequency specificity of the ABR. Notched noise masking …

Comparative Analysis Of Serologic Assays For The Detection Of Antibodies To Eastern Equine Encephalomyelitis Virus In Sentinel Chickens, Christy L. Voakes

USF Tampa Graduate Theses and Dissertations

Florida's mild climate supports year round enzootic transmission of arthropod-borne (arbo) viruses, such as St. Louis Encephalitis virus (SLEV), West Nile virus (WNV), and Eastern Equine Encephalomyelitis virus (EEEV). First isolated in 1960 from two Florida blue jays, Highlands J virus (HJV) is endemic to the state and vectored by the same mosquitoes as EEEV (Henderson et al, 1962). EEEV and HJV are both alphaviruses, but HJV is not pathogenic to humans, occasionally causes encephalitis in horses, and is a recognized pathogen in some bird species (turkeys, emus, etc) (Cilnis et al, 1996).

The Florida Sentinel Chicken Arboviral Surveillance …

Towards Adaptation Of Ofdm Based Wireless Communication Systems, Sharath Reddy Billoori

USF Tampa Graduate Theses and Dissertations

OFDM has been recognized as a powerful multi-carrier modulation technique that provides efficient spectral utilization and resilience to frequency selective fading channels. Adaptive modulation is a concept whereby the modulation modes are dynamically changed based on the perceived instantaneous channel conditions. In conjunction with OFDM systems, adaptive modulation is a very powerful technique to combat the frequency selective nature of mobile channels, while simultaneously attempting to fully maximize the time-varying capacity of the channel. This is based on the fact that frequency selective fading affects the sub-carriers unevenly, causing some of them to fade more severely than others. The modulation …

The Politics Of Being An Egg “Donor” And Shifting Notions Of Reproductive Freedom, Elizabeth A. Dedrick

USF Tampa Graduate Theses and Dissertations

As an Assisted Reproductive Technology (ART) that has been available for over twenty years, the transfer of healthy eggs from a presumably fertile woman into the womb of a woman diagnosed as infertile has become a common part of the landscape of human reproduction in the United States. Yet the general societal acceptance of this practice commonly known as "egg donation" oversimplifies the complex medical, ethical, and societal issues ignited by its use. In light of the limited critical discussions presently occurring about egg transfer, I will interrogate some of the silences and more ambiguous issues invoked by its practice. …

Light Quality And Phytoplankton Viability, Lisa A. Malick

USF Tampa Graduate Theses and Dissertations

A method is presented, using calculations of the underwater light field, to examine viability of phytoplankton at depth. For this study, viability is defined as the ability of phytoplankton to harvest, and efficiently convert enough photons into primary production to overcome metabolic demands. How the available light field influences the production environment is examined. Changes in water column constituents, such as chlorophyll and colored dissolved organic matter (CDOM) concentration, alter the spectral quality and quantity of the light field at depth. Certain species with specialized survival strategies, such as assemblages of photoprotective and light-harvesting accessory pigments, may be better-suited to …

From Just War To Just Peace: Re-Visioning Just War Theory From A Feminist Perspective, Naomi Malone

USF Tampa Graduate Theses and Dissertations

This paper studies the history of just war theory and critiques it from various feminist perspectives. Using a definition of war as inseparable from the system within which it is embedded, the paper contends that just war theory has been incorporated into the realist paradigm that predominates current political thought, making it susceptible to manipulation. Most importantly, this usurpation has shifted just war theory's focus from jus ad bellum to jus in bello considerations, seriously weakening its deterrent effects on war. The paper proposes its replacement with a just peace theory, discussing several existing frameworks and explaining the important part …

Modeling Time Space Prism Constraints In A Developing Country Context, Ram S. Nehra

USF Tampa Graduate Theses and Dissertations

Recent developments in microsimulation modeling of activity and travel demand have called for the explicit recognition of time-space constraints under which individuals perform their activity and travel patterns. The estimation of time-space prism vertex locations, i.e., the perceived time constraints, is an important development in this context. Stochastic frontier modeling methodology offers a suitable framework for modeling and identifying the expected vertex locations of time space prisms within which people execute activity-travel patterns. In this work, stochastic frontier models of time space prism vertex locations are estimated for samples drawn from a household travel survey conducted in 2001 in the …

Concerning Theories Of Personal Identity, Patrick, Bailey

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis is to provide a brief examination of the historical accounts of philosophical theories of personal identity and show the influence that each has had on the development of contemporary theories. In doing so, the thesis explores the problems associated with these theories, attempting to establish a meta-theory (i.e. a theory about theories) of personal identity. What is demonstrated is that the fundamental problems of personal identity arise from issues related to the use of language, as well as assumptions involving the concept of personhood.

By demonstrating that our understanding of personhood is relative to frameworks …

This thesis investigates the performance of TCP and newer TCP versions over High Bandwidth Delay Product Channels (HBDPC), such as the on demand optical channels described above. In addition, …

An Online Strategy For Wavelet Based Analysis Of Multiscale Sensor Data, Alok K. Buch

USF Tampa Graduate Theses and Dissertations

Complex industrial processes are represented by data that are well known to be multiscaled due to the variety of events that occur in a process at different time and frequency localizations. Wavelet based multiscale analysis approaches provide an excellent means to examine these events. However, the scope of the existing wavelet based methods in the fields of statistical applications, such as process monitoring and defect identification are still limited. Recent literature contains several wavelet decomposition based multiscale process monitoring approaches including many real life process monitoring applications, such as tool-life monitoring, bearing defect monitoring, and monitoring of ultra-precision processes such …

A Comparison Of Exhaled Breath Nitric Oxide Between Old And Young Individuals, Robert L. Gordon

USF Tampa Graduate Theses and Dissertations

BACKGROUND: Older individuals suffer from higher rates of pulmonary infections than younger individuals. In addition, older individuals have increased morbidity and mortality due to pulmonary infections when compared to younger individuals. The physiological and immunological reasons for these aforementioned differences are not clear. Recently, non-invasive markers of the lung's physiologic and immunologic status have been recognized. This study employs one of these non-invasive markers, exhaled nitric oxide, in an attempt to determine how the airways may change with age, predisposing older individuals to pulmonary diseases and poorer outcomes as compared to younger individuals.

METHODS: Exhaled nitric oxide measurements were obtained …
