Infrared Thermography And High Accuracy Gps For Automated Asphalt Crack Detection, Tarek M. Abdel-Monem
Electronic Theses and Dissertations
Roads are major public assets. The USA spends billions of dollars each year on road construction and maintenance. To keep these roads in a healthy condition and for better planning and allocation of maintenance budgets, knowledge of distressed locations is needed. Roads develop cracks when they are subjected to stresses that exceed their designed criteria or their materials properties. Early detection and repair of cracks has proven to be the most cost-effective strategy in limiting the damage to roads and reducing expenditures. Various methodologies of crack detection were developed and significant techniques were made in the last few years. One …

Cascading Effects Of Predator Removal On The Ecology Of Sea Turtle Nesting Beaches, Brandon Barton
Cascading Effects Of Predator Removal On The Ecology Of Sea Turtle Nesting Beaches, Brandon Barton
Electronic Theses and Dissertations
Traditional views of food web dynamics have characterized species interactions as linear and direct. However, modern food web theory suggests that interactions can also be nonlinear and indirect, so that disturbance at one trophic level is transmitted throughout the community. Many previous studies have demonstrated that the removal of top predators from terrestrial ecosystems can have broad-scale impacts on community ecology. I examined the direct and indirect effects of raccoon removal from sea turtle nesting beaches in east-central Florida during the summers of 2003 and 2004. Raccoon and ghost crab predation are among the highest causes of egg mortality for …
The Effects Of Electrode Geometry On Current Pulse Caused By Electrical Discharge Over An Ultra-Fast Laser Filament, Matthew Bubelnik
The Effects Of Electrode Geometry On Current Pulse Caused By Electrical Discharge Over An Ultra-Fast Laser Filament, Matthew Bubelnik
Electronic Theses and Dissertations
The time-resolved electrical conductivity of a short-pulse generated plasma filament in air was studied. Close-coupled metal electrodes were used to discharge the stored energy of a high-voltage capacitor and the resulting microsecond-scale electrical discharge was measured using fast current sensors. Significant differences in the time dependence of the current were seen with the two electrode geometries used. Using sharp-tipped electrodes additional peaks in the time-resolved conductivity were seen, relative to the single peak seen with spherical electrodes. We attribute these additional features to secondary electron collisional ionization brought about by field enhancement at the tips. Additional discrepancies in the currents …

Internet Advertising: Are We Breaking Ground Or Moving Dirt?, Jaime Marshall
Electronic Theses and Dissertations
Seeking to validate the Elaboration Likelihood Model (ELM) of Persuasion for the online advertising context, a laboratory experiment utilizing 240 undergraduates was conducted at a southeastern university. The quality of banner advertisement contents--product endorser (spokesperson) and arguments (headlines)--were manipulated testing the variables' effect on click-through and attitude toward the advertisement for groups with high and low levels of product category involvement. Exploring a replica of a popular music website, participants were exposed to the test banners on the site's homepage. Due to the limited number of click-throughs, the relationship between the independent variables and click-through could not be established. However, …

Advances In The Opto-Mechanical Design And Alignment Of The Hehsi Imaging Spectrometer Based On A Sagnac Interferometer, Michael Stuart Schreiber
Electronic Theses and Dissertations
The High Efficiency HyperSpectral Imager (HEHSI) is a Fourier Transform hyperspectral imager based on a Sagnac interferometer. This thesis research concentrates on the design upgrade and calibration of HEHSI from a proof of concept instrument to a prototype field instrument. Stability is enhanced by removing degrees of freedom and alignment is enhanced by providing for in-situ adjustments. The use of off the shelf components allows for reduced development time and cost constraints. HEHSI is capable of multiple configurations to accommodate sensors and optics with specialized capabilities for multiple wavelength ranges and viewing conditions. With a spectral response of 400 to …

Plant City, Florida, 1885-1940: A Study In Southern Urban Development, Mark W. Kerlin
Plant City, Florida, 1885-1940: A Study In Southern Urban Development, Mark W. Kerlin
Electronic Theses and Dissertations
This study investigates the development of Plant City, Florida as a railroad town developing on the Southwest Florida frontier from 1885-1940. The study chronicles the town's origins and economic, political, and social development in relationship to the broader historical theories of southern urban development, specifically those put forward in David Goldfield's pioneering work, Cotton Fields and Skyscrapers: Southern City and Region 1607-1980. Goldfield contended that southern cities developed differently than their northern counterparts because they were not economically, politically, philosophically and culturally separated from their rural surroundings. Instead, they displayed and retained the positive and negative attributes of southern society …
Confocal Laser Scanning Microscopy As A Tool For The Investigation Of Tetracycline Fluorescence In Archaeologicalhuman Bone, Corey Maggiano
Confocal Laser Scanning Microscopy As A Tool For The Investigation Of Tetracycline Fluorescence In Archaeologicalhuman Bone, Corey Maggiano
Electronic Theses and Dissertations
Fluorochromes such as tetracycline have been used to label bone for histomorphometric analysis, measuring bone formation, growth, maintenance, and pathology. More recently, similar fluorescence has been observed in ancient human bone. Attributed to tetracycline (TC) exposure, this phenomenon could affect various aspects of health during life and/or preservation of remains postmortem. Standard epifluorescence microscopy is the most common tool employed in the analysis of these labels. Though valuable, this technique is limited by its inability to penetrate bone three-dimensionally and its inclusion of out-of-focus light, possibly disrupting accurate analysis. Confocal Laser Scanning Microscopy (CLSM) has been demonstrated as a valuable …
