The Salvation Army And Government Funding - Blessing Or Bane?, Noreen Scott

Master's Theses

This study was conducted to explore the issues surrounding government funding of faithbased nonprofit organizations. The main question addressed was what, if any, are the positives and negatives for a religious nonprofit faith-based organization accepting government funding. This study examined the Salvation Army, a faith-based 50l(c)(3) charitable organization with a long history of accepting government funding for its social service programs. Seven Salvation Army administrators were interviewed to determine whether government funding for this organization's social services had any impact on the organization in four specific areas:

1. Finances

2. Staffing

3. Administrative reporting

4. Mission

Three noteworthy issues were …

Sic Etch Development In A Lam Tcp 9400se Ii System, Janna Rea Bonds

Theses and Dissertations

SiC etch development has been performed in a Lam TCP 9400SE II system (a system meant for polysilicon etching and modified for SiC etching). SiC etching has never been reported in this particular system. Various parameters (carrier material, pressure, gas additives, gas flow, and electrode power) were examined and their effects determined on etch rate and resulting surface morphology. An efficient carrier material (graphite), operating pressure (25 mTorr), and gas flow rate (30 sccm) for obtaining peak etch rates were determined for this system. Peak etch rates of 1254 Å/min. in CHF3:O2, 4314 Å/min. in SF6:O2, and 1255 Å/min. in …

Error Estimation And Grid Adaptation For Functional Outputs Using Discrete-Adjoint Sensitivity Analysis, Ravishankar Balasubramanian

Theses and Dissertations

Within the design process, computational fluid dynamics is typically used to compute specific quantities that assess the performance of the apparatus under investigation. These quantities are usually integral output functions such as force and moment coefficients. However, to accurately model the configuration, the geometric features and the resulting physical phenomena must be adequately resolved. Due to limited computational resources a compromise must be made between the fidelity of the solution obtained and the available resources. This creates a degree of uncertainty about the error in the computed output functions. To this end, the current study attempts to address this problem …

Adsorption Of Organic Pollutants Onto Natural Adsorbents, Arun Subramani

Theses and Dissertations

In this research, the adsorptive capacities of kenaf, peat moss, hay, and peanut hulls were evaluated for the removal of TNT and 2,4-DCP from aqueous solutions. Adsorbent loading capacities determined by batch studies were verified by continuous column experiments. It was found that the adsorption capacity of the candidate adsorbents were significantly lower than granular activated carbon (GAC). The impact of surface modification techniques, such as surface oxidation, were evaluated to study the effect on adsorption capacity. At lower equilibrium concentrations of the adsorbate (less than 10 ppb), surface oxidation by ozone showed an increase in the adsorption capacity. The …

Two And Three-Dimensional Finite Element Analysis Of Plasticity-Induced Fatigue Crack Closure: A Comprehensive Parametric Study, Kiran N. Solanki

Theses and Dissertations

Finite element analyses are frequently used to model growing fatigue cracks and the associated plasticity-induced crack closure. Two-dimensional, elastic-perfectly plastic finite element analyses of middle-crack tension (M(T)), bend (SEB), and compact tension (C(T)) geometries were conducted to study fatigue crack closure and to calculate the crack opening values under plane-strain and plane-stress conditions. The loading was selected to give the same maximum stress intensity factor in both geometries, and thus similar initial forward plastic zone sizes. Mesh refinement studies were performed on all geometries with various element types. For the C(T) geometry, negligible crack opening loads under plane-strain conditions were …

Best Effort Mpi/Rt As An Alternative To Mpi: Design And Performance Comparison, Raghavendra Angadi

Theses and Dissertations

The Real-Time Message Passing Interface (MPI/RT) is an emerging real-time communications middleware standard for distributed real-time applications. The Message Passing Interface (MPI) is the de facto standard for high performance parallel application development. In this thesis, we describe how MPI/RT with best effort quality of service can be used as an alternative for MPI. Mercury Computer Systems' RACE embedded parallel computer is used as the platform for comparison of design and performance of these two standards. The main advantages MPI/RT has over MPI are its explicit support for communication channels and its emphasis on early binding. Design and implementation of …

Dimensionality Reduction Of Hyperspectral Signatures For Optimized Detection Of Invasive Species, Abhinav Mathur

Theses and Dissertations

The aim of this thesis is to investigate the use of hyperspectral reflectance signals for the discrimination of cogongrass (Imperata cylindrica) from other subtly different vegetation species. Receiver operating characteristics (ROC) curves are used to determine which spectral bands should be considered as candidate features. Multivariate statistical analysis is then applied to the candidate features to determine the optimum subset of spectral bands. Linear discriminant analysis (LDA) is used to compute the optimum linear combination of the selected subset to be used as a feature for classification. Similarly, for comparison purposes, ROC analysis, multivariate statistical analysis, and LDA are utilized …

Integration Of Zero-Valent Metals And Chemical Oxidation For The Destruction Of 2,4,6-Trinitrotoluene Within Aqueous Matrices, Rafael Hernandez

Theses and Dissertations

The Department of Defense (DoD) has numerous sites that contain groundwater contaminated with 2,4,6-trinitrotoluene (TNT). The currently applied technologies for treating TNT contaminated waters are carbon adsorption and chemical oxidation. Carbon adsorption is a non-destructive technology, which could create future liability issues and is inefficient at relatively low TNT concentrations. On the other hand, application of chemical oxidation for the treatment of TNT contaminated water generates trinitrobenzene (TNB), a by-product of the incomplete oxidation of TNT. TNB is regulated as strictly as TNT. Additionally, over 70% of the reactor required treatment time for meeting target levels is due solely for …

Linear Unmixing Of Hyperspectral Signals Via Wavelet Feature Extraction, Jiang Li

Theses and Dissertations

A pixel in remotely sensed hyperspectral imagery is typically a mixture of multiple electromagnetic radiances from various ground cover materials. Spectral unmixing is a quantitative analysis procedure used to recognize constituent ground cover materials (or endmembers) and obtain their mixing proportions (or abundances) from a mixed pixel. The abundances are typically estimated using the least squares estimation (LSE) method based on the linear mixture model (LMM). This dissertation provides a complete investigation on how the use of appropriate features can improve the LSE of endmember abundances using remotely sensed hyperspectral signals. The dissertation shows how features based on signal classification …

Relationships Between Reflectance And Soil Physical And Chemical Properties, Abdulrahman Mohammed Alrajehy

Theses and Dissertations

Soil chemical and physical properties are important to farm productivity, and they vary within fields, so farmers are interested in managing inputs like fertilizer according to local soil conditions within fields. Thus, they must have knowledge of soil conditions of interest, which have historically been measured at a few locations with tedious soil sampling and laboratory analyses. Advantageous to farmers would be a measurement method that provided more geographically detailed information at similar or lower cost. Remote and ground-based optical sensing are possibilities for gathering detailed soil information rapidly and inexpensively. This study considers the possibility of optically measuring soil …

Experimental Studies Of The Drag Of An Axisymmetric Submarine Hull, John Lindsley Freudenthal

Theses and Dissertations

The purpose of these studies was to measure the drag coefficient of a small model submarine to add data to a Reynolds number study. First, a laser Doppler velocimeter (LDV) was used to measure the flow characteristics of the Mississippi State University water tunnel. The velocity and turbulence intensity profiles were measured for a range of freestream velocities of 8.6 m/s to 10.7 m/s. Several wake velocity profiles were taken for a model submarine at downstream distances of x/d = 10 to x/d = 28, with a freestream velocity of 8.6 m/s. A formula for the drag coefficient that uses …

A Framework For Automatic Ontology Generation From Autonomous Web Applications, Giovanni Modica

Theses and Dissertations

Ontologies capture the structure, relationships, semantics and other essential meta information of an application. This thesis describes a framework to automate application interoperability by using dynamically generated ontologies. We propose a set of techniques to extract ontologies from data accessible on the Web in the form of semi-structured HTML pages. Ontologies retrieved from similar applications are matched together to create a general ontology describing the application domain. Information retrieval and graph matching techniques are used to match and measure the usefulness of the ontologies created. Matching algorithms are combined together to produce global ontologies based on local ontologies inherently present …

Accuracy Study Of A Free Particle Using Quantum Trajectory Method On Message Passing Architecture, Ravi K. Vadapalli

Theses and Dissertations

Bhom's hydrodynamic formulation (or quantum fluid dynamics) is an attractive approach since, it connects classical and quantum mechanical theories of matter through Hamilton-Jacobi (HJ) theory, and quantum potential. Lopreore and Wyatt derived and implemented one-dimensional quantum trajectory method (QTM), a new wave-packet approach, for solving hydrodynamic equations of motion on serial computing environment. Brook et al. parallelized the QTM on shared memory computing environment using a partially implicit method, and conducted accuracy study of a free particle. These studies exhibited a strange behavior of the relative error for the probability density referred to as the transient effect. In the present …

An Analysis For Evaluating The Cost/Profit Effectiveness Of Parallel Systems, Maria Teran

Theses and Dissertations

A new domain of commercial applications demands the development of inexpensive parallel computing platforms to lower the cost of operations and increase the business profit. The calculation of returns on an IT investment is now important to justify the decision of upgrading or replacing parallel systems. This thesis presents a framework of the performance and economic factors that are considered when evaluating a parallel system. We introduce a metric called the cost/profit effective metric, which measures the effectiveness of a parallel system in terms of performance, cost and profit. This metric describes the profit obtained from the performance of three …

Modeling Of Evaporation And Condensation Pressure-Drop In Micro-Fin Tubes, Meng-Onn Tan

Theses and Dissertations

Three existing pressure-drop models are validated and analyzed with experimental data compiled from the research database. From the analysis, it was found that the pressure-drop prediction results from the models are not very accurate and not consistent with all experimental datasets. A new pressure-drop model was consequently created based on the findings from the study, and experimental data from the database were used to validate the model to produce more accurate and consistent predictions. The new pressure-drop model was tested on experimental datasets that were in the database and also with experimental datasets that were not in the database. Good …

Scheduling For Proportional Differentiated Services On The Internet, Manimaran Selvaraj

Theses and Dissertations

Proportional Differentiated Services can be provisioned in terms of bandwidth, delay, or packet loss. Several studies contributed schedulers and packet droppers that achieved proportional bandwidth, delay, or loss differentiation. However, all these schemes differentiated in terms of only one of the three metrics. A simple, unified, scalable, and robust scheme to simultaneously control all three metrics was felt important. By controlling just delay and packet loss, proportional differentiation can be achieved in terms of all three metrics. A robust adaptive scheduler for proportional delay differentiation services is presented. Proportional services are further policed by a class based packet dropper. The …

Small Signal Stability Of An Unregulated Power System, Vikas Singhvi

Theses and Dissertations

Rotor angle stability is the ability of the interconnected synchronous machines of a power system to remain in synchronism. This stability problem is concerned with the behavior of one or more synchronous machine after they have been perturbed. These perturbations can be small or large depending upon the type of disturbances considered. The work presented in this thesis is focused on the power system behavior when subjected to small disturbances. The ?small signal? disturbances are considered sufficiently small for the linearization of system equations to be permissible for the purpose of the analysis. The first step in the small signal …

The influence of obstacle reflectivity, composition and area on the size and shape of the radar detection zone are discussed. An experimental setup for measuring position and velocity of the obstacle crossing the truck path …

Growth Of 6h-Sic Homoepitaxy On Substrates Off-Cut Between The [01-10] Planes, James Dennis Vandersand Jr

Theses and Dissertations

The wide band-gap semiconductor silicon carbide has tremendous potential for use in high power, high temperature, and high frequency electronic devices. One of the more important design factors for these devices is the epitaxial layer. It is desirable that this thin film have uniform polytype, thickness, and impurity concentration, as well as be defect free. One method used for SiC to ensure epitaxial layers with homogenous polytype is to cut wafers from a boule that has been tilted towards a specific crystallographic face at a fixed angle (known as ?off cut?). The purpose of this thesis was to investigate the …
