New Visualization Techniques For Multi-Dimensional Variables In Complex Physical Domains, Rhonda J. Vickery

Theses and Dissertations

This work presents the new Synthesized Cell Texture (SCT) algorithm for visualizing related multiple scalar value fields within the same 3D space. The SCT method is particularly well suited to scalar quantities that could be represented in the physical domain as size fractionated particles, such as in the study of sedimentation, atmospheric aerosols, or precipitation. There are two components to this contribution. First a Scaling and Distribution (SAD) algorithm provides a means of specifying a multi-scalar field in terms of a maximum cell resolution (or density of represented values). This information is used to scale the multi-scalar field values for …

Improvements On Heat Flux And Heat Conductance Estimation With Applications To Metal Castings, Xingjian Xue

Theses and Dissertations

Heat flux and heat conductance at the metal mold interface plays a key role in controlling the final metal casting strength. It is difficult to obtain these parameters through direct measurement because of the required placement of sensors, however they can be obtained through inverse heat conduction calculations. Existing inverse heat conduction methods are analyzed and classified into three categories, i.e., direct inverse methods, observer-based methods and optimization methods. The solution of the direct inverse methods is based on the linear relationship between heat flux and temperature (either in the time domain or in the frequency domain) and is calculated …

Quality Improvements In Extruded Meshes Using Topologically Adaptive Generalized Elements, Satish Chalasani

Theses and Dissertations

In this dissertation, a novel method to extrude near-body meshes from surface meshes of arbitrary topology that exploits topologically adaptive generalized elements to improve mesh quality is presented. Specifically, an advancing layer algorithm to generate near-body meshes which are appropriate for viscous fluid flows is discussed. First, an orthogonal two-layer algebraic reference mesh is generated. The reference mesh is then smoothed using a locally three-dimensional Poisson-type mesh generation equation that is generalized to smooth extruded meshes of arbitrary surface topology. Local quality improvement operations such as edge collapse, face refinement, and local reconnection are performed in each layer to drive …

Limitations Of Principal Component Analysis For Dimensionality-Reduction For Classification Of Hyperspectral Data, Anil Meerasa Cheriyadat

Theses and Dissertations

It is a popular practice in the remote-sensing community to apply principal component analysis (PCA) on a higher-dimensional feature space to achieve dimensionality-reduction. Several factors that have led to the popularity of PCA include its simplicity, ease of use, availability as part of popular remote-sensing packages, and optimal nature in terms of mean square error. These advantages have prompted the remote-sensing research community to overlook many limitations of PCA when used as a dimensionality-reduction tool for classification and target-detection applications. This thesis addresses the limitations of PCA when used as a dimensionality-reduction technique for extracting discriminating features from hyperspectral data. …

Visual Framing: A Study In Face-Ism From The Websites For The 108th United States Congress., Beth Johnson Anderson

Electronic Theses and Dissertations

Websites are being used by increasing numbers to target a market with a message unfiltered by the media. This content analysis examined the website front-screens for the members of the 108th United States Congress to determine if the photographic images displayed reinforced the media's stereotypical frame of female politicians. A total of 3,892 photographic images were captured from 540 websites and coded using the face-ism index. Overall, the results supported the face-ism theory. Images of females were cropped lower on their bodies than images of males. The face-ism effect was not supported until the number of people in the photograph …

Jeffersonianism And 19th Century American Maritime Defense Policy., Christopher Taylor Ziegler

Electronic Theses and Dissertations

This paper analyzes the fundamental maritime defense mentality that permeated America throughout the early part of the Republic. For fear of economic debt and foreign wars, Thomas Jefferson and his Republican party, opposed the construction of a formidable blue water naval force. Instead, they argued for a small naval force capable of engaging the Barbary pirates and other small similar forces. For protection of the nation and commerce, they wanted a strictly defensive strategy developed around coastal gunboats and harbor fortifications. This research will analyze the naval aspect of this defense mentality from its creation in 1794, through the War …

Towards A Taxonomy Of Aspect-Oriented Programming., Mario Bernard Hankerson

Electronic Theses and Dissertations

As programs continue to increase in size, it has become increasingly difficult to separate concerns into well localized modules, which leads to code tangling- crosscutting code spread throughout several modules. Thus, Aspect-Oriented Programming (AOP) offers a solution to creating modules with little or no crosscutting concerns. AOP presents the notion of aspects, and demonstrates how crosscutting concerns can be taken out of modules and placed into a centralized location.

In this paper, a taxonomy of aspect-oriented programming, as well as a basic overview and introduction of AOP, will be presented in order to assist future researchers in getting started on …

Interworking Methodologies For Dcom And Corba., Edwin Kraus

Electronic Theses and Dissertations

The DCOM and CORBA standards provide location-transparent access to network-resident software through language independent object interfaces. Although the two standards address similar problems, they do so in incompatible ways: DCOM clients cannot use CORBA objects, and CORBA clients cannot utilize DCOM objects, due to incompatible object system infrastructures.

This thesis investigates the performance of bridging tools to resolve the incompatibilities between DCOM and CORBA, in ways that allow clients to cross object system boundaries. Two kinds of tools were constructed and studied: tools that bind clients to services at compile time, and tools that support dynamic client-server bindings. Data developed …

A Sense Of Place., Neli Ilieva Ouzounova

Electronic Theses and Dissertations

Concerned with anxiety and displacement, the artist explores a sense of place within the self. Personal experiences are presented as an accumulation of fragmented symbols, textures and pattern. Symbolic imagery is being created, influenced by a devaluation of established norms and a reorganization of cultural identity. The individualÆs interaction and experience with the surrounding world affirms his idiosyncratic symbolism. The artwork is a visual language that through the use of disparate segments sets up the portrayal of the fragmented self and psychological journeys of the artist.

Individuals establish themselves in many ways, including gestures as part of expression. This expression …

The Osteogenic Effects Of 12 Weeks Of Oral Supplementation Of Androstenedione In Middle-Aged Men., Troy Matthew Wills

Electronic Theses and Dissertations

Recent evidence suggests that declining bone mineral density (BMD) in males is related to declining circulating estrogens. The majority of endogenous plasma estrogens in males result from peripheral aromatization of plasma androgens. Thus, it was hypothesized that dietary supplementation with an aromatizable androgen (androstenedione) may stimulate increases in BMD.

BMD (measured by dual energy x-ray absorptiometry) and biochemical markers of bone turnover (1, 25 OH2 Vitamin D, calcitonin, deoxypyrodinoline, and parathyroid hormone) were assessed before and after 12 weeks of dietary androstenedione supplementation (200 mg/d). Twenty-four volunteers were randomized into either an androstenedione supplementation or placebo groups. Study volunteers also …

An Analytical Method To Determine The Mechanical Properties Of Linear Viscoelastic Solids, Rani W. Sullivan

Theses and Dissertations

A new methodology has been developed to model the viscoelastic behavior of solids using a general spectrum function. Not all materials can be modeled using simple Kelvin-Voigt (K-V) or Maxwell elements where the viscoelastic parameters are constants. There is a need for a general spectrum function that can be used to model the Lame' functions which constitute all properties of interest. Thus far, there is no method like the one presented in this study that can determine the moduli of viscoelastic materials. This study develops a methodology by which the time dependent properties of homogeneous and non-homogeneous materials may be …

Coupling Heat Transfer And Fluid Flow Solvers For Multi-Disciplinary Simulations, Qingyun Liu

Theses and Dissertations

The purpose of this study is to build, test, validate, and implement two heat transfer models, and couple them to an existing fluid flow solver, which can then be used for simulating multi-disciplinary problems. The first model is for heat conduction computations, the other one is a quasi-one-dimensional cooling channel model for water-cooled jacket structural analysis. The first model employs the integral, conservative form of the thermal energy equation, which is discretized by means of a finite-volume numerical scheme. A special algorithm is developed at the interface between the solid and fluid regions, in order to keep the heat flux …
