Computational Simulations Concerning Unsteadiness Attenuation In Axial Turbines, Robert R. Croft

Theses and Dissertations

Axial turbomachines have inherently unstable flow fields due to the interaction between rotating and nonrotating blade rows. In addition, combustor instabilities add considerable stress on the blading via the introduction of localized radial and/or circumferential temperature discontinuities known as hot streaks. To alleviate the losses due to nonconformities within the turbine a computational effort has been undertaken investigating the effects of clocking an imbedded stage in a multi- stage axial turbine and a separate study considering the effects of an imposed temporally oscillating hot streak within a 1 1/2 stage turbine. Time-dependent hot streak results show little relation of rotor …

Neodymium And Erbium Coordination Environments In Phosphate Glasses, Mevlüt Karabulut, G. K. Marasinghe, Ezzeldin Metwalli, Andrew K. Wittenauer, Richard K. Brow, C. H. Booth, D. K. Shuh

Materials Science and Engineering Faculty Research & Creative Works

The local structures of Nd3+ and Er3+ ions in two series of rare-earth (RE) phosphate glasses with nominal compositions xR203-(1-x)P2O5, where R=Nd and Er and 0.05≤x≤0.28, have been characterized by LIII-edge extended x-ray-absorption fine-structure spectroscopy (EXAFS). The RE coordination number depends on the R2O3 content, decreasing from 9.0 (10) oxygen nearest neighbors in ultraphosphate compositions (x<0.15) to 6.4 (9) oxygen nearest neighbors for the metaphosphate (x∼0.25) compositions. The average Er-O bond distance decreases from 2.29 (1) to 2.23 (1) Å, and the average Nd-O bond distance decreases from 2.40 (1) to 2.37 (1) Å over the same compositional range. The changes in coordination environments are consistent with the conversion of isolated RE polyhedra to clustered RE polyhedra sharing common oxygens as the number of available terminal oxygens per RE ion decreases with increasing x.

Microstructure Determination In A Self Assembled Surfacant System Formed By Aot/Lecithin/Isooctane And Water, Vivek Agarwal

Open Access Master's Theses

We have observed a novel transformation from a microemulsion to a gel phase by increasing the water content of a system consisting of bis(2-ethylhexyl) sodium sulfosuccinate (AOT), phosphatidycholine(lecithin), and 2,2,4 -trimethylpentane (isooctane). The viscosity increases by six orders of magnitude and a rigid gel forms as the water content is increased above a specific threshold. Small angle neutron scattering (SANS) experiments on this surfactant mesophase reveal the microstructure as columnar hexagonal at lower water contents and temperatures, and lamellar at higher water contents and temperatures. SANS is also able to capture the transition between these two structures. These structures are …

The Fringing Halophytic Vegetation Of Lake Austin: A Study Of Mining Impacts And Vegetation Dynamics, Simone Vellekoop

Theses : Honours

Mining operations in arid regions of Western Australia are faced with many environmental management issues. One such issue is the disposal of mine water to the environment. Mine water is commonly discharged to nearby salt lakes under licence by the Department of Environmental Protection. Licence conditions dictate that the discharge water and the receiving environment be monitored to allow impacts on the environment to be detected. Salt lakes are associated with vegetation communities dominated by halophytic members of the Chenopodiaceae, While these plants are tolerant of salinity extremes, the germination stage of many species requires periods of lowered salinity. There …

Empirical Characteristic Function In Time Series Estimation, J. Knight, Jun Yu

Research Collection School Of Economics

Policymakers seeking to design efficient and smoothly functioning pension systems for their aging workforces are beginning to acknowledge the key importance of administrative expenses when formulating rules for pension plan structure and fee disclosure requirements. This study explores the links between retirement plan offerings and pension expenses for a wide range of private and public sector pension plan types, using an invaluable new data set on two thousand Australian pension funds. Our analysis indicates how pension plan design can strongly influence plan expenses and consequently eventual retirement security.

Monitoring Process Variability With Symmetric Control Limits, Zhenlin Yang

Research Collection School Of Economics

Control charts for monitoring process variability, such as the R-chart and S-chart, do not have symmetric probability limits as the distribution of the sample variability is not normal. Hence, the usual zone rules can not be applied although it is still desirable to be able to use the information from more than one point in decision making. In this paper, a modified S-chart based on an optimal normalizing transformation of the sample variance is first introduced. The new chart is shown to have approximate symmetric probability limits and hence can be interpreted in the same way as that of a …

Performance Modeling And Prediction For The Scalable Solution Of Partial Differential Equations On Unstructured Grids, Dinesh Kumar Kaushik

Computer Science Theses & Dissertations

This dissertation studies the sources of poor performance in scientific computing codes based on partial differential equations (PDEs), which typically perform at a computational rate well below other scientific simulations (e.g., those with dense linear algebra or N-body kernels) on modern architectures with deep memory hierarchies. We identify that the primary factors responsible for this relatively poor performance are: insufficient available memory bandwidth, low ratio of work to data size (good algorithmic efficiency), and nonscaling cost of synchronization and gather/scatter operations (for a fixed problem size scaling). This dissertation also illustrates how to reuse the legacy scientific and engineering software …

Corporate Governance In The Cause Of Peace: An Environmental Perspective, Donald O. Mayer

Vanderbilt Journal of Transnational Law

This Article examines the role of multinational corporations in creating global peace. Part I discusses the role of multinational corporations in the global economy, emphasizing the relationship between multinational corporations, governments, and the environment. Part II explores whether corporations have a moral duty to oppose ill-conceived laws and policy proposals and to support well-conceived laws that encourage efficiency and sustainability, but may hinder short-term profitability. Part III expands and further explores the argument set forth in Part II by examining the continuing dependency of the United States and other industrialized democracies on oil from the Middle East. Part IV concludes …

"Super Jumbo" Problem: Boeing, Airbus, And The Battle For The Geopolitical Future, Daniel L. Fisher

Vanderbilt Journal of Transnational Law

The commercial aircraft industry is important to the United States for both economic and political reasons. Economically, commercial aviation has been the linchpin of the military-industrial complex and a positive actor on many other segments of U.S. industry. Politically, Boeing has ensured the lead of the United States in the aviation industry and aviation exports, which have a beneficial effect on the ability of the United States to export geopolitical power.

Cognizant of this salutary effect of a successful aviation industry on the United States, Europe created and financed Airbus as a direct competitor to Boeing, hoping it would play …

Health Versus Trade: The Future Of The Who's Framework Convention On Tobacco Control, Alyssa Woo

Vanderbilt Journal of Transnational Law

On October 16, 2000, the World Health Organization (WHO) began the first session of negotiations of its first international health treaty, the Framework Convention on Tobacco Control (FCTC). Scheduled for adoption in May 2003, the FCTC is a comprehensive multilateral treaty that will cover everything from tobacco smuggling to tobacco advertising and the extent of the liability of tobacco companies.

This Note argues that even-handed domestic measures implementing the FCTC will be protected from international, trade-based complaints because the World Trade Organization's dispute settlement system has given sufficient and appropriate content to the health exception to the normal trade rules …

The Single Row Routing Problem Revisited: A Solution Based On Genetic Algorithms, Albert Y. Zomaya, Roger Karpin, Stephan Olariu

Computer Science Faculty Publications

With the advent of VLSI technology, circuits with more than one million transistors have been integrated onto a single chip. As the complexity of ICs grows, the time and money spent on designing the circuits become more important. A large, often dominant, part of the cost and time required to design an IC is consumed in the routing operation. The routing of carriers, such as in IC chips and printed circuit boards, is a classical problem in Computer Aided Design. With the complexity inherent in VLSI circuits, high performance routers are necessary. In this paper, a crucial step in the …

The Fullest Possible Accounting: The Myth Of American Pow/Mias In Southeast Asia, David L. Sutton

Iowa Journal of Communication

This essay examines the Vietnam War POW/MIA myth, the belief in the existence of living, breathing Americans soldiers still held captive in the remote jungles of Southeast Asia. This essay takes the position that the Vietnam War POW/MIA myth is not the sole product of a slick and manipulative U.S. government public relations campaign; rather, this contemporary myth finds its origin in the American monomyth, a long-standing cultural narrative.

Object Persistence And Availability In Digital Libraries, Michael L. Nelson, B. Danette Allen

Computer Science Faculty Publications

We have studied object persistence and availability of 1,000 digital library (DL) objects. Twenty World Wide Web accessible DLs were chosen and from each DL, 50 objects were chosen at random. A script checked the availability of each object three times a week for just over 1 year for a total of 161 data samples. During this time span, we found 31 objects (3% of the total) that appear to no longer be available: 24 from PubMed Central, 5 from IDEAS, 1 from CogPrints, and 1 from ETD.

Federated Searching Interface Techniques For Heterogeneous Oai Repositories, Xiaoming Liu, Kurt Maly, Mohammad Zubair, Qiaoling Hong, Michael L. Nelson, Frances Knudson, Irma Holtkamp

Computer Science Faculty Publications

Federating repositories by harvesting heterogeneous collections with varying degrees of metadata richness poses a number of challenging issues: (1) how to address the lack of uniform control for various metadata fields in terms of building a rich unified search interface, and (2) how easily new collections and freshly harvested data in existing repositories can be incorporated into the federation supporting a unified interface? This paper focuses on the approaches taken to address these issues in Arc, an Open Archives Initiative compliant federated digital library. At present Arc contains over 1M metadata records from 75 data providers from various subject domains. …

Fast Inner Product Computation On Short Buses, R. Lin, S. Olariu

Computer Science Faculty Publications

We propose a VLSI inner product processor architecture involving broadcasting only over short buses (containing less than 64 switches). The architecture leads to an efficient algorithm for the inner product computation. Specifically, it takes 13 broadcasts, each over less than 64 switches, plus 2 carry-save additions (t_csa) and 2 carry-lookahead additions (t_cla) to compute the inner product of two arrays of N = 2⁹ elements, each consisting of m = 64 bits. Using the same order of VLSI area, our algorithm runs faster than the best known fast inner product algorithm of Smith and Torng …

A Critical Exploration Of The School Context For Young Adolescents Completing Primary Education [Thesis], Sasha A. Stumpers

Theses : Honours

Recent research suggests that students' classroom engagement, increased academic effort, and subsequent success or failure arc not only influenced by individual differences in skills and pre-dispositions, but also by the school context. However, there is a need to further investigate the school context in relation to the well-being of the collective through concepts such as power and control. Therefore, this research sought to critically explore young adolescents' perceptions and experiences of their school context. Furthermore, how year seven students experience their school prior to the transition into high school was investigated. Using a semi-structured interview schedule, 8 male and 7 …

John Forrest: Western Australia Under The Banyan Tree, Zoë Janina Yökki Joy Trotman

Theses : Honours

This story is about a man named John Forrest, my great-great-great uncle. I want to Investigate how he shaped and enacted upon the space we now call the State of Western Australia: as explorer, as surveyor, and as Premier. The photographs in my thesis explore how he impacted upon the landscape that we currently observe: they illustrate ways in which his past influence can be detected in the landmarks of our state, and they act as evidence of the “bigger picture”, demonstrating the effects his influence has had on the present condition of the land itself. Forrest helped construct many …

Travellers And The Industrial Revolution: Observations Of Cornwall, Cynthia Lane

Theses : Honours

The following dissertation is a "contribution to contemporary debates about the industrial revolution and the perpetuation of 'differcnce'."¹ It covers the era of Cornish industrialisation and the attendant socio-economic and cultural changes from the emergence of copper mining in the 1690s to the eve of its crash in 1866, through the observations of a selection of contemporary travellers/writers. It explores the image of Com wall through West Barbary versus Industrial Civilisation, and compares the county's processes of industrialisation with the canonical industrial revolution of the midlands and the north of England. Cornwall is examined as an example of the …

Growth Dependant Properties Of Undoped And In-Situ Doped Chemically Deposited Cds Thin Films, Aaron John Reynolds

Theses : Honours

This research project examines the growth dependant properties and composition of Cadmium Sulfide thin films produced by the Chemical Bath Deposition Method. The specific areas investigated are the effect of deposition temperature, the effect of an Indium dopant on the films structure and properties, and the effects of post deposition processing such as annealing in air on the film composition. The chemical bath deposition apparatus used has been refined and tested to ensure that the films were grown in a more efficient manner than previously, with more control of the influencing deposition parameters such as temperature. Films grown by the …

Using Simulated Annealing In Geostatistics, Wesley Wells

Theses : Honours

Simulation methods are now used extensively for estimation and prediction in mining and petroleum industries and also in environmental management. In this thesis we describe the method of simulated annealing and examine in detail the GSLIB implementation algorithm SASJM. In the context of two case studies involving both sample and exhaustive data sets, we demonstrate this algorithm and then investigate the effect on the outcome of varying the different algorithm parameters. We also consider the effect of varying the weighting given in the simulated annealing objective function to the reproduction of each of the sample histogram and semivariogram. For the …
