Real-Time Multimedia-Based Education Through The Internet, Abhay Arun Bakshi Dec 1998

Real-Time Multimedia-Based Education Through The Internet, Abhay Arun Bakshi

Graduate Theses, Dissertations, and Problem Reports (ETD)

The rapid advances in computer and communications technologies are challenging the American education systems to provide increased educational opportunities beyond the traditional geographic boundaries at a reasonable cost. Many educational institutions are answering this challenge by developing distance education programs. Distance education provides effective learning environment. An important requirement for effective distance education is the availability of continuous interactivity and immediate feedback. Over the Internet, synchronous sharing of multimedia content introduces unacceptable delays as network bandwidth is limited. In this thesis, the issue of Internet bandwidth is minimized and a novel system is developed for distance education using multimedia course …

Computational Modeling Of Brittle Impact Erosion Mechanisms, Shanmuga Sundaram Balasubramaniyam Dec 1998

Computational Modeling Of Brittle Impact Erosion Mechanisms, Shanmuga Sundaram Balasubramaniyam

Graduate Theses, Dissertations, and Problem Reports (ETD)

Materials are subjected to an erosion-corrosion environment in a wide range of applications today. Elevated temperatures promote the formation of oxide layers in jet engines. In fluidized bed boilers, the bed materials and piping of slurries and caustic materials cause erosion and corrosion. The process of erosion-corrosion may result in material loss and damage. Proper analytical modeling of the erosion-corrosion processes validated by experiments is needed to estimate the extent of damage in the material.;Empirical relations are available in the literature for predicting the amount of material loss due to erosion. These are obtained by conducting large number of experiments. …

Determination And Analysis Of Natural Gas Vehicle Tailpipe Emissions Based On Continuous Cvs Measurement, Jingang Fu Dec 1998

Determination And Analysis Of Natural Gas Vehicle Tailpipe Emissions Based On Continuous Cvs Measurement, Jingang Fu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Code of Federal Regulations Title 40 (CFR-40) specified a formula for calculating constant Dilution Factor (DF) to account for background pollutants in Constant Volume Sampler (CVS) emissions measurement system. However, it is recognized that the DF is dynamically changing due to the CVS mechanism. Based on the continuous measurement data obtained from natural gas vehicle emissions testing, a new approach was used in this study to calculate instantaneous DF of the CVS system during the test cycle. Using the instantaneous DF improves the accuracy of mass emission measurements, especially when the exhaust pollutant concentrations were approaching that in the ambient …

Rheological Properties Of Candle Filter Deposits At Elevated Temperatures And Pressures, Brian Robert Jordan Dec 1998

Rheological Properties Of Candle Filter Deposits At Elevated Temperatures And Pressures, Brian Robert Jordan

Graduate Theses, Dissertations, and Problem Reports (ETD)

In order to improve the performance of hot gas ceramic candle filters, the theological properties of two types of filter deposits were studied. Black powder from the IGCC (Integrated Gasification Combined Cycle) provided consistent data when sampled from two different sources. This powder's mechanical properties were independent of elevated temperature conditions, suggesting that the particle adhesion process is controlled by the theological properties of the powder. Per US DOE request an apparatus was built to more accurately simulate candle filtration, and it was used to show that the process was unaffected by elevated inlet pressure conditions. The system was modeled …

Productive Performance And Fertility Of Broiler Breeders Maintained In Commercial Colony Cages And On The Conventional Floors, Kitogho J. Mwashighadi Dec 1998

Productive Performance And Fertility Of Broiler Breeders Maintained In Commercial Colony Cages And On The Conventional Floors, Kitogho J. Mwashighadi

Graduate Theses, Dissertations, and Problem Reports (ETD)

A trial with four replicates was conducted to compare performance and fertility of naturally mated broiler breeders maintained on litter floor versus their counterparts maintained in two tiered colony cages. Cage maintained hens with restricted feeding weighed less (P 0.05) was found in egg weights among treatments. No difference (P > 0.01) was found in feed conversion ratio per dozen eggs produced by hens maintained in cages and those on the conventional floors. A higher (P < 0.05) hen-day production was observed from 29 to 35 weeks of age in broilers maintained in cages than those on the conventional floors, but after this period no difference (P > 0.05) occurred. There were more (P < 0.05) eggs collected with cracks from cages than from the litter floors. The fertility rate was different (P 0.05) difference in mortality rate occurred between hens maintained on the fitter floors versus those in cages. When the breeders were 41 weeks of age, eggs from each treatment group were randomly collected, weighed, and incubated. Offspring from these treatments were randomly allocated to litter floor pens. Progeny were spaced at 23 CM.2 and were reared to 42 days. There was no significant (P > 0.05) difference in growth rate and feed conversion ratio in offspring from hens maintained on the litter floors versus …

Velocity Profile In Confined Elliptic Fractures, Stephen Ronald Pack Jr. Dec 1998

Velocity Profile In Confined Elliptic Fractures, Stephen Ronald Pack Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

The primary objective of this research is to determine the friction inside a smooth fracture and to incorporate the effect of friction on a fluid transient inside a tapered-elliptical-confined fracture. In order to do so, the non-uniform velocity profile in an elliptic fracture with laminar flow of both Newtonian and non-Newtonian fluids was calculated. A transient flow computer program is presented using the method of characteristics, to show the frictional effects on acoustic damping. However for flow inside a hydraulic fracture, the 3D velocity profile is highly non-uniform, and the use of Vav creates an error as Vmax >> Vav. The …

Investigation Of The Formation Of Residual Ash On Candle Filters, Sharath J. Simha Dec 1998

Investigation Of The Formation Of Residual Ash On Candle Filters, Sharath J. Simha

Graduate Theses, Dissertations, and Problem Reports (ETD)

When coal undergoes combustion, not all the carbon in the coal may be consumed. This is due to improper mixing of reactants, proximity of cold surfaces and the desire to operate combustors at lower temperatures. Depending on the type of coal and the operating conditions of the combustor, there may be about 4--6% of unburned carbon in the refuse. This unburned carbon is carried along in the flow of gases and ash. If the combustion gas products are to pass through a high temperature gas filtration system, ash and unburned carbon are deposited on the wall of a candle filter. …

Computational Models Of Particle Size Effects On Brittle Oxide Scale Erosion, Ravi S. Tangirala Dec 1998

Computational Models Of Particle Size Effects On Brittle Oxide Scale Erosion, Ravi S. Tangirala

Graduate Theses, Dissertations, and Problem Reports (ETD)

Metals and alloys designed for machines at elevated temperatures have microstructures and chemistries optimized to provide strength and resistance to oxidation. The majority of the commercial high temperatures metal or alloys intended to use at temperatures below 850°C or so rely on the formation of a continuous surface layer of essentially oxide scale for further oxidation resistance. Erosion of these machine parts by the small solid particle entrained in the liquid or gaseous working environment is a serious problem in many industrial applications. Numerous experiments have been conducted to obtain empirical relations for predicting material loss during erosion and to …

Prediction Of Turbulent Mixing At The Interface Of Density Stratified, Shear Flows Using Cfd, Matthew Robert Umbel Dec 1998

Prediction Of Turbulent Mixing At The Interface Of Density Stratified, Shear Flows Using Cfd, Matthew Robert Umbel

Graduate Theses, Dissertations, and Problem Reports (ETD)

Numerical simulations were performed involving stratified, shear flows that have been investigated experimentally. One set of simulations dealt with a homogeneous shear flow involving miscible fluids. The other set of simulations dealt with a developing shear layer involving immiscible fluids. The re-fueling of a compensated fuel/ballast tank, which is partially characterized by a shear layer, was also simulated. In all the simulations a single fluid, scalar transport multiphase model and the k-epsilon turbulence model were used. In the simulations involving miscible fluids an interfacial thickness relationship given by delta/H∼(Ri*)--2.1 and an entrainment relationship given by E∼(Ri*)--1.1 were predicted. These relationships …

Pseudospectral Techniques For Non -Smooth Evolutionary Problems, Chris Palmer Guenther Dec 1998

Pseudospectral Techniques For Non -Smooth Evolutionary Problems, Chris Palmer Guenther

Graduate Theses, Dissertations, and Problem Reports (ETD)

A pseudospectral approach is used to solve non-smooth evolutionary problems using Fourier collocation and Chebyshev collocation. It is well known that pseudospectral methods for smooth problems can offer superior accuracy over finite difference and finite element methods.;This paper explores the use of pseudospectral methods for non-smooth evolutionary problems in the area of hyperbolic heat transfer. Boundary and initial conditions are considered which cause instantaneous jumps, in the temperature and flux, prior to the propagation of a thermal wave into the medium. There is a considerable amount of literature that has investigated hyperbolic heat transfer under similar conditions, the common problems …

Waiting With Brother Thomas, Chris Sagers Dec 1998

Waiting With Brother Thomas, Chris Sagers

Law Faculty Articles and Essays

In this Essay, Christopher Sagers argues that those schools of thought that could be called "doubtful"—that is, those predicated on suspicion of belief to some degree—share a range of similarities and, more importantly, are attacked through a set of common criticisms. He argues that the fundamental criticism of these "doubtful" schools of thought—that doubt leads us to nihilism and therefore must be bad—is a non sequitur. Furthermore, he continues, we reject doubt not because it is bad, but because it is difficult. Ultimately, he suggests ways to face the problems of nihilism or, rather, ways of understanding them as other …

Principal Component Mapping Applied To Raman Microspectroscopy Of Fiber-Reinforced Polymer Composites, C. M. Stellman, K. S. Booksh, A. R. Muroski, M. P. Nelson, Michael L. Myrick

Faculty Publications

We describe the development and implementation of a spectroscopic Raman imaging system using Principal Component data analysis. Raman microspectroscopy followed by multivariate data analysis and principal component mapping has been used to investigate the spatial variations of chemical and physical properties at interfaces in glass-reinforced composites on the micrometer scale. A protocol for monitoring chemical and physical variances via multivariate statistics has been developed and a preliminary study of a "real world" glass-reinforced composite is presented. It is demonstrated that multivariate Raman imaging is more precisely interpretable than traditional univariate methods and that by appropriately choosing distinct spectral regions (such …

"Wildly Enthusiastic" About The First Multilateral Agreement On Trade In Telecommunications Services, Laura B. Sherman Dec 1998

"Wildly Enthusiastic" About The First Multilateral Agreement On Trade In Telecommunications Services, Laura B. Sherman

Federal Communications Law Journal

In 1998, the World Trade Organization’s (WTO) "Basic Telecom Agreement" dramatically opened to foreign competition basic telecommunications services of the sixty-nine WTO Members committing to the Agreement. The process and results of the WTO negotiations are important to telecommunications consumers because there will be increased market competition, thereby decreasing the price of such services and increasing consumer choice. The negotiations that led to the WTO Agreement resolved many difficult issues including: scheduling, regulator’s independence, competitive safeguards, and interconnection of telecommunications suppliers. The resolution of these issues will allow market access and foreign ownership in over 90 percent of major markets. …

The Anglicans In New Guinea And The Torres Strait Islands, David Wetherell Dec 1998

The Anglicans In New Guinea And The Torres Strait Islands, David Wetherell

Pacific Studies

This study compares the Anglican diocese of Carpentaria in northeastern Australia with its Anglican neighbor the diocese of New Guinea. While New Guinea called for sacrifice on a heroic scale as befitted a mission among pure “pagans,” Carpentaria was intended primarily as a church for Europeans. However, the withdrawal of thousands of settlers from the Gulf of Carpentaria country from 1910 to 1942 in the wake of recurrent cyclones, economic depression, and drought led to wholesale white depopulation. This depopulation, added to the Anglicans’ acceptance of the London Missionary Society’s sphere in the Torres Strait Islands, left Carpentaria overwhelmingly Islander …
