Precipitation And Inter-Event Dry Periods For Selected Areas Of Florida, Teresa Rae Lineback

Retrospective Theses and Dissertations

The increase in the pollution of existing water bodies due to poor management of storwater runoff has demanded continuous re-evaluation of present design methods for stormwater management facilities. Current criteria used in determining water quality (treatment) volumes in pond design neglect antecedent conditions resulting from preceding rainfall. The inter-event dry period refers to that time period (hours) which occurs between rainfall events. The

minimum inter-event dry period used for pollution control design should be consistent with the time required for infiltration, chemical precipitation, sediment removal, and biological assimilation; as well as the period of time required to minimize the cumulative …

Surface Mapping And Automatic Tool Path Generation, Labiche Ferreira

Retrospective Theses and Dissertations

With the use of machine vision systems in the manufacturing cycle of a product, the lead time for producing the final product has been substantially reduced. Efforts in the past have aimed at automating the tasks right from the drawing board stage to final production of the product. Such technologies include CAD, CAM, and CAPP. However the task of tool path (NC code) generation has not yet been fully automated. In the current techniques, the user plays a crucial role in the NC code generation process. There is an increasing trend for using machine vision systems in the fabrication of …

Photorefractive Materials For Optical Signal Processing, William B. Lawler

Retrospective Theses and Dissertations

The optical response of the photorefractive crystals KNbO₃:Ta, KNbO₃:Fe, LiNbO₃:Fe, and nominally pure BaTiO₃ is investigated. In the experiment, a holographic grating is built in the crystal under investigation via a two-wave mixing scheme that utilizes the signal-processing capacities of two acousto-optic Bragg cells. The dynamic interaction of the Bragg cells with the photorefractive grating causes a heterodyned RF signal to appear on the output laser beam, enabling the real-time, direct measurement of the amplitude and phase of the space-charge fields in the crystal. Experimental results are presented for the amplitude and phase …

Application Of A Six-State Passive Track Filter Within A Weapon-Delivery System For A Lock-On-After-Launch Missile, Lynda Jeanne Ciaponi

Retrospective Theses and Dissertations

Knowing the benefits that a passive air target tracking system gives the host aircraft attempting to conceal its own presence on the battlefield, it is desired to determine whether the aircraft can also deliver one of its own lock-on-after-launch air-to-air missiles to the target via use of the same passive system. The objective of this thesis is to demonstrate that a passive six-state track filter can be successfully used within such a weapon delivery system. The role of the filter within the system is to track the enemy target in cartesian space utilizing only line-of-sight measurements and to track the …

Texture Segmentation And Classification Using Fractal And Energy Measures, Qing Chen

Retrospective Theses and Dissertations

This thesis introduces a multi-feature based texture segmentation and classifi­ cation algorithm. We first present general background on segmentation approaches which can be categorized into three groups : characteristic thresholding and clus­ tering, edge detection, and region merging. According to our texture segmentation objective, we choose characteristic thresholding and clustering along with region merging as our segmentation method which is accomplished by a popular K-mean algorithm applied in the feature space. Fractal geometry is receiving increasing attention as a model for natural phe­ nomena. We present an efficient method for estimating the fractal dimension of image surfaces and show that …

Design Curves For The Reuse Of Stormwater, Gregory Miller Harper

Retrospective Theses and Dissertations

The reuse of stormwater runoff is becoming an increasingly popular addition to stormwater management systems. The advantages include a reduction in pollution and volume discharges to surface waters, the return of runoff to the ground, and savings in the cost of using potable water. This research, by developing a relationship between the reuse volume (temporary storage volume), the rate at which stormwater is reused, and the percentage of annual surface runoff that is reused, provides a procedure in which to design stormwater reuse systems. The traditional design of pond temporary storage volume has been based on the consideration of water …

Rs170 Image Processing Interface, Charlotte Christou

Retrospective Theses and Dissertations

This thesis deals with the hardware design and implementation of an image processing board that digitizes RS-170 video, passes it thru a sobel filter and sends the results to a high-resolution color printer. Most sobels deal with black and white images, but this thesis uses a static color image. The hardware design will allow direct printing from a RGB separate channel RSl 70 video source to a Tektronix 4693DX Color Printer through a Centronics port. It will also allow the red, blue and green video channels to pass through a sobel filter, with the resulting image being sent out to …

An Analysis Of The Parameters Affecting The Stabilization Rate Of Yard Waste Compost, Patricia G. Fleming

Retrospective Theses and Dissertations

In recent times, municipalities have turned to yard waste composting in an effort to comply with mandated recycling and reduction laws aimed at extending existing landfill capacity. Composting is a biological process whereby decomposition of organic matter occurs under aerobic conditions, producing a stabilized humified material. The objective of the research was to analyze data gathered during pilot yard waste composting operations utilizing the windrow method. The following tasks were accomplished: temperature and oxygen profiles from daily monitoring data were examined and the effect these parameters had on stabilization was determined; stabilization time of varying yard waste matrices was compared …

Combined Photolasticity And Elastostatic Boundary Element Method In Solid Mechanics Applications, Troy Duane Jensen

Retrospective Theses and Dissertations

Considerable efforts have recently been made on combining experimental and numerical techniques in a so called "hybrid" method for stress analysis. One of these techniques is combining photoelastic "experimental" data with the boundary element "numerical" method. Most of this work has centered on using the boundary element method to solve the potential problem (i.e., Laplace's equation) where external boundary conditions must be specified. The results are combined with the photoelastic isochromatic information to separate the principal stresses at any desired interior location. This thesis, however, concentrates on combining the photoelastic data with the elastostatic boundary element method. This is advantageou~ …

The Enhancemnt Of N-Heptane Vapor Incineration Using Ozone And Hydrogen Peroxide, Michael William Hewett

Retrospective Theses and Dissertations

Using a narrow bore quartz tube reactor set inside a three zone Lindburg furnace, a measured air stream with a known concentration of n-heptane was heated to temperatures between 637°C and 687°C. A separate measured air stream with known concentrations of ozone was injected just prior to the thermal zone of the reactor. The differences in heptane concentration entering and exiting the reactor under varying time, temperature, and ozone conditions were monitored with a gas chromatograph in an effort to generate kinetic data. The reactor was modeled as a first order plug flow reactor. The constants in the Arrhenius equation …

Dehydrobromination Of Some 1,3-Dibromo-1,1- Difluoro Compounds Som (4+2) Cycloaddition Reactions Of 1,1-Difluoro-1,3-Dienes, Christopher Foti

Retrospective Theses and Dissertations

The title 1,3-dibromo- l, l-difluoro compounds are dehydrobrominated in the presence of l,8-diazabicyclo[5.4.0]undec-7-ene (DBU). Reaction of simple saturated dibromides with DBU at 25 °C affords moderate yields of monoelimination products in which the reaction is 100% stereoselective and regioselective. Highly conjugated dienes are synthesized at mild reaction conditions in contrast to simple alkyl or pentafluorophenyl dienes which are inaccessible via a double dehydrobromination reaction due to the unexpected formation of trifluoromethyl compounds. Aromatic gem-difluorodienes react with 4-phenyl-1,2,4-triazoline-3,5-dione and a mechanistic experiment demonstrates the relative reactivities of the isomers of 1, l-difluoro-4-phenyl-1,3-butadiene in a Diels-Alder reaction. The unfluorinated analogue of 1, …
