A Nonlinear Transient Approach for Morton Synchronous Rotordynamic Instability and Catcher Bearing Life Predictions
(2012-07-16)
This dissertation deals with three research topics; i) the catcher bearings life prediction method, ii) the Morton effect, and iii) the two dimensional modified Reynolds equation.
Firstly, catcher bearings (CB) are ...
Frequentist-Bayes Goodness-of-fit Tests
(2012-10-19)
In this dissertation, the classical problems of testing goodness-of-fit of uniformity and parametric families are reconsidered. A new omnibus test for these problems is proposed and investigated. The new test statistics ...
Analyzing the Limits and Extent of Alpha-Amylase Catalyzed Removal of Starch-Based Filter Cake
(2012-02-14)
The ability of starch to impart functions including fluid-loss control, cuttings transport, and rheological characteristics to water-based drilling fluids has led to its widespread use in the oil industry. The filter cake ...
Macroeconomic Study of Construction Firm's Profitability Using Cluster Analysis
(2012-10-19)
This research aims to identify important factors contributing to a construction firm's profitability and to develop a prediction model which would help in determining the gross margin/profitability of a construction firm ...
Determination of Longitudinal Stress in Rails
(2012-02-14)
The objective of this research is to determine the longitudinal stress in rails by using the polarization of Rayleigh waves. Analytical models are developed to describe the effect of applied stress on wave speed and on the ...
Female Blow Fly (Diptera: Calliphoridae) Arrival Patterns and Consequences for Larval Development on Ephemeral Resources
(2012-07-16)
This investigation explored the environmental and physiological factors affecting adult blow fly (Diptera: Calliphoridae) arrival and attendance at pig (Sus scrofa domesticus L.) carcasses in Brazos Co, TX in the summer ...
High-Resolution Carbon Isotope Stratigraphy, Pennsylvanian Snaky Canyon Formation, East-Central Idaho: Implications for Regional and Global Correlations
(2012-07-16)
Nearly 550 samples of fine grained carbonates, collected every 0.5 to 1.0 m from the Bloom Member of the Snaky Canyon Formation at Gallagher Peak, Idaho, were analyzed to determine the high-resolution carbon isotope ...
The Analysis and Conservation of Two 18-pounder Carronades from the U.S. Navy Schooner Shark
(2012-07-16)
In February of 2008, two 18-pounder carronades were discovered off the Oregon coast near Arch Cape in Clatsop County. In addition to the carronades, several associated artifacts were collected from the site, including ...
Effect of Bioreactor Mode of Operation on Mixed-Acid Fermentations
(2012-10-19)
Using mixed-culture fermentation, the carboxylate platform produces carboxylic acids, which are chemically converted into chemicals and fuels. To optimize the mixed-acid fermentation, different bioreactor configurations ...
CTCF Contributes to the Regulation of the Ribosomal DNA in Drosophila melanogaster
(2012-02-14)
The 35S rDNA gene clusters on the X and Y chromosomes of Drosophila melanogaster are repeats of approximately 150 to 225 copies. Each are transcribed as a single unit by RNA Polymerase I and modified into the 18S, 5.8S, ...
