Histogram Specification Of 24-Bit Color Images In The Color Difference (C-Y) Color Space, A. R. Weeks, L. J. Sartor, H. R. Myler

Faculty Bibliography 1990s

Histogram equalization and specification have been widely used to enhance information in a gray scale image, with histogram specification having the advantage of allowing the output histogram to be specified as compared to histogram equalization, which attempts to produce an output histogram that is uniform Unfortunately, expanding histogram techniques to color images is not very straightforward Since humans are sensitive to chromatic changes, care must be taken to ensure that incorrect colors are not produced. Additionally expanding the one-dimensional histogram used in gray level histogram techniques to a joint histogram (usually of three variables representing the primary colors of red, …

Nscat Normalized Radar Backscattering Coefficient Biases Using Homogenous Land Targets, Josko Zec, David G. Long, W. Linwood Jones

Faculty Bibliography 1990s

The NASA scatterometer (NSCAT) is a spaceborne radar sensor designed to measure the normalized radar backscattering coefficient sigma(o) of the Earth's surface. Over the ocean, backscatter measurements are used to infer surface wind vectors. Wind retrieval is based on a statistical relationship between short-ocean wave roughness (that causes the backscatter) and the surface wind speed and direction. For NSCAT geometry, multiple antennas are used to provide backscatter measurements at several azimuth directions to resolve wind direction ambiguities. To achieve the desired wind vector accuracy, these antenna beams must be calibrated within a few tenths of a decibel. A simple relative-calibration …

Nitrogen Incorporation And Trace Element Analysis Of Nanocrystalline Diamond Thin Films By Secondary Ion Mass Spectrometry, D. Zhou, F. A. Stevie, L. Chow, J. Mckinley, H. Gnaser, V. H. Desai

Faculty Bibliography 1990s

Nitrogen has been successfully incorporated into nanocrystalline diamond films produced by a CH4/N-2 microwave plasma-enhanced chemical vapor deposition method. High mass resolution secondary ion mass spectrometry (SIMS) characterization shows that the density of the incorporated nitrogen, monitored via CN-, can be as high as 10(21) atoms/cm(3) depending on the ratio of CH4 to N-2 in the reactant gas and on the substrate temperature used for the film preparation. SIMS depth profiles demonstrate that the incorporated nitrogen is uniform within the diamond films (about 1.5 mu m thick) except at the surfaces and at the interface between film and substrate. Furthermore, …

Behavioral And Physiological Responses Of The Lobster, Homarus Americanus, To Temperature: A New Synthesis, Steven Harold Jury

Doctoral Dissertations

Temperature has a pervasive influence on lobster behavior, physiology and ecology and affects their subsequent distribution in thermally variable habitats such as estuaries and coastal areas. A multidisciplinary approach, including field and laboratory studies, was used to show: (1) that lobsters sense temperature with warm and cool thresholds as small as 0.1--0.2°C; (2) the relationship between temperature and activity is not linear, but instead switches between a high activity level in warmer months (10--20°C) and a lower level in colder months (<10°C) with transition periods in the spring and fall; (3) Parallel studies in the lab and field show that daily levels of activity are not greatly influenced by small temperature variations (i.e. tidally induced changes of 14°C), but activity levels are significantly higher in the field (249 +/- 55.1 m/d) than in the laboratory (88 +/- 12.0 m/d); (4) lobsters prefer a narrow range of temperatures over others available in a thermal gradient and avoid temperatures >23.5 +/- 0.4°C, suggesting that they behaviorally thermoregulate. While this preferred temperature shifts seasonally, the final preferred temperature …

Preparation And Characterization Of Derivatized Microparticles Immobilized In Hydrogel Membranes For Optical Chemical Sensing Based On Polymer Swelling, Eric William Miele

Doctoral Dissertations

Hydrogel membranes containing aminated microparticles have been investigated for reflectance based optical sensing. The membranes were evaluated by UV/Vis spectrophotometry, for potential use in a remote distributive fiber optic chemical sensor. This work describes efforts for improving the signal and decreasing the overall response time of the membranes. The microparticles were prepared by dispersion and seeded emulsion polymerization techniques. The microparticles were derivatized to introduce pH sensitivity. The hydrogel membranes containing swellable microparticles are turbid. Scattering occurs at the microparticle-hydrogel interface and is based on refractive index changes accompanying polymer swelling. The particles swell in response to hydrogen ion concentration, …

Topics In Chaotic Secure Communication, Andrew Thomas Parker

Doctoral Dissertations

Results in nonlinear dynamics and chaos during this decade have been applied to problems in secure communications with limited success. Most of these applications have been based on the chaotic synchronization property discovered by Pecora and Carroll in 1989 [37]. Short [44, 45, 48] demonstrated the effectiveness of nonlinear dynamic (NLD) forecasting methods in breaking this class of communication schemes. In response, investigators have proposed enhancements to the basic synchronization technique in an attempt to improve the security properties. In this work two of these newer communication systems will be analyzed using NLD forecasting and other techniques to determine the …

New Methods For Modeling Accelerated Life Test Data, Michelle Hopkins Capozzoli

Doctoral Dissertations

An accelerated life test (ALT) is often used to obtain timely information for highly reliable items. The increased use of ALTs has resulted in nontraditional reliability data which can not be analyzed with standard statistical methodologies. I propose new methods for analyzing ALT data for studies with (1) two independent populations, (2) paired samples and (3) limited failure populations (LFP). Here, the Weibull distribution, which can accommodate a variety of failure rates, is assumed for the models I develop. For case (1), a parametric hypothesis test, a Bayesian analysis and a test using partial likelihood are proposed and discussed. For …

Hardware-Software Codesign In A High-Level Synthesis Environment, Tamas L. Visegrady

Doctoral Dissertations

Interfacing hardware-oriented high-level synthesis to software development is a computationally hard problem for which no general solution exists. Under special conditions, the hardware-software codesign (system-level synthesis) problem may be analyzed with traditional tools and efficient heuristics. This dissertation introduces a new alternative to the currently used heuristic methods. The new approach combines the results of top-down hardware development with existing basic hardware units (bottom-up libraries) and compiler generation tools. The optimization goal is to maximize operating frequency or minimize cost with reasonable tradeoffs in other properties.

The dissertation research provides a unified approach to hardware-software codesign. The improvements over previously …

A Constraint-Based Framework For Configuration, Daniel Sabin

Doctoral Dissertations

The research presented here aims at providing a comprehensive framework for solving configuration problems, based on the Constraint Satisfaction paradigm. This thesis is addressing the two main issues raised by a configuration task: modeling the problem and solving it efficiently. Our approach subsumes previous approaches, incorporating both Simplification and further extension, offering increased representational power and efficiency.

Modeling. We advance the idea of local, context independent models for the types of objects in the application domain, and show how the model of an artifact can be built as a composition of local models of the constituent parts. Our modeling technique …

The Mut-2 Mutator Of Caenorhabditis Elegans, Kathrine Queta Flint Boese

Doctoral Dissertations

The mut-2 mutator plays multiple regulatory roles in the germ line of C. elegans. In addition to regulating germ line transposition of at least four distinct transposon families (Tc1, Tc3, Tc4 and Tc5) mut-2 is implicated in chromosome segregation. Animals that harbor the mut-2 mutator produce broods with a higher incidence of males phenotype (Him) as a result of an increase in X chromosome non-disjunction during meiosis.

Using the Him phenotype conferred by mut-2(r459), I mapped the gene to the dpy-14 sem-4 interval on LGI. However, efforts to identify a molecular clone of the gene were hampered because the available …

The Development Of Rna Probe And Rt-Pcr Assays For The Detection Of Enteroviruses In Sludge, Amy Elisabeth Moore

Doctoral Dissertations

Many wastewater treatment plants generate more sludge than can be disposed of by conventional means. The United States Environmental Protection Agency (USEPA) has encouraged communities to dispose of sludge by land application. Sludge may contain enteric viruses that are known to survive for long periods of time in sludge-amended soil and can travel great distances, potentially contaminating surface and ground water.

Standard cell culture methods for the detection of enteric viruses are costly and results are not obtained for 30 or more days. The development of methods that provide results more quickly and with lower cost are needed.

The Dynamics Of Rotor With Rubbing, Jerzy T. Sawicki, Joe Padovan, Rabih Al-Khatib

Mechanical Engineering Faculty Publications

This paper presents the description of some phenomena associated with dynamic behavior of rotors interacting with stationary components. Numerical simulations show rotor vibration spectrum rich in subharmonic, quasi-periodic, and chaotic vibrations. The nonlinear calculation techniques are applied to demonstrate the changes of the vibration patterns for different operating conditions. Some conclusions are discussed with regard to unique characteristics of rub-induced rotor response, initial conditions, as well as appropriate ranges of system parameters. Of special interest are the changes in the apparent nonlinearity of the system dynamics as rubs are induced at different rotor speeds. In particular, starting with 2nd order …

Borderland "Day Tourists" From The East: Trieste's Transitory Shopping Fair, Julian V. Minghi

Visions in Leisure and Business

Flows of people across international boundaries to shop have long been a common phenomenon. The end of the Cold War removed barriers to such flows from Eastern to Western Europe and gave rise to a distinctive strain of borderland shopper-officially a "day tourist" from Central Europe, but in reality a professional shopper working as an essential part of an international retail distribution system linking supply from the West to consumption in the East. The case of Trieste (Italy) is examined. The city's borderland shoppers became important during the late 1980s and activity peaked in 1993-5 as bus loads of Central …

Segmentation As A Method For Improving Model Generated Estimates Of Recreational Boating Use, Tsung-Chiung Wu, Edward M. Mahoney, Daniel J. Stynes

Visions in Leisure and Business

The primary purpose of this study is to develop a system of models based on boat storage segments that can generate different estimates of boating use for regions and counties. It is based on the premise that models. that incorporate market segmentation are more efficient and generate more accurate estimates of recreational use when a market is comprised of identifiable market segments. The results show that incorporating storage segments as part of the system of models improves estimates of both the amount and spatial distribution of boating use. The boating use estimates generated by the system of models captures the …
