A Comparative Fault Diagnosis Methodology Based On Time Series Analysis Of System's Signals, Hany Bassily Dec 2007

A Comparative Fault Diagnosis Methodology Based On Time Series Analysis Of System's Signals, Hany Bassily

All Dissertations

The detection of system anomalies represents an important task in safety critical systems. Over the past two decades, advances in data manipulation techniques and sensor technology have contributed to the widespread application of signal processing concepts for fault diagnosis. However, the majority of these signal processing, or data driven, diagnostics do not possess the redundancy level exhibited in conventional model-based methods. Among signal processing methods, time series analysis is advantageous since it offers insight into the underlying dynamics and forecasts system behavior. Furthermore, the data driven method allows the depiction of system dynamics with an increased level of redundancy. This …

Techniques For Improving The Performance Of Coupled Oscillator Arrays, Venkatesh Seetharam Dec 2007

Techniques For Improving The Performance Of Coupled Oscillator Arrays, Venkatesh Seetharam

All Dissertations

Coupled oscillator arrays (COAs) have excellent synchronization properties that can be utilized to develop a low cost alternative to phased array systems for beam steering applications. The primary concerns in implementing the COA architecture are the sensitivity to cell-to-cell component variation and poor phase noise performance. Wide injection locking range oscillators reduce the sensitivity to component variation but degrade the array phase noise performance. The objective of this dissertation is to alleviate the concerns hindering the application of COAs by employing techniques to realize COAs with wide mutual injection locking ranges (MILR), improved phase noise characteristics and beam steering capabilities. …

Enhancing The Ability Of Panicum Virgatum To Survive Flooding And Its Effects On Soil Activity When Used For Lakeshore Stabilization, Lee Edwards Dec 2007

Enhancing The Ability Of Panicum Virgatum To Survive Flooding And Its Effects On Soil Activity When Used For Lakeshore Stabilization, Lee Edwards

All Dissertations

Reservoirs in upstate South Carolina are subject to erosion and vegetation has been placed to help stabilize banks, but soils are nutrient-poor and have high bulk densities. Panicum virgatum L. (switchgrass) has been planted in several sites, and it is hypothesized that over time, changes in microbial activity and soil quality will occur in response to the planting. As vegetated sites aged, acid phosphomonoesterase, nitrate reductase, and dehydrogenase activity increased. Low values of nitrogen fixation and substrate-induced respiration were measured at all sites with no statistical differences between sites. Fatty acids indicative of Gram negative bacteria were found in vegetated …

An Experimental And Numerical Study Of The Film Casting Process, Kenneth Aniunoh Dec 2007

An Experimental And Numerical Study Of The Film Casting Process, Kenneth Aniunoh

All Dissertations

Film casting is a common industrial process used to produce polymeric films. During film casting, a polymer melt is extruded through a flat die before rapid cooling on a chill roll. The chill roll velocity is faster than the velocity at which the melt exits the die, thus the polymer melt is stretched and oriented in an extensional flow. The material properties and processing conditions have a significant impact on the process and the final thermal/mechanical properties of the film produced.
Optimization of industrial scale film casting processes is still greatly dependent on trial and error methods. Therefore, this work …

Ultrahydrophobic Surface Modification Of Polymeric Fibers And Inorganic Substrates, Karthik Ramaratnam Dec 2007

Ultrahydrophobic Surface Modification Of Polymeric Fibers And Inorganic Substrates, Karthik Ramaratnam

All Dissertations

The wettability of a solid surface is a very important property, and is governed by both the chemical composition and the geometrical microstructure of the surface. Wettability and repellency are important properties of solid surfaces from both fundamental and practical aspects. The wettability of the solid surface is a characteristic property of materials and strongly depends on both the surface energy and the surface roughness. These properties may be approached by mimicking hydrophobic structures created by nature on lotus leaf surface. The lotus effect is based on surface roughness caused by different microstructures together with the hydrophobic properties of the …

Effect Of Carbon Nanofibers On Microstructure And Properties Of Polymer Nanocomposites, Sungho Lee Dec 2007

Effect Of Carbon Nanofibers On Microstructure And Properties Of Polymer Nanocomposites, Sungho Lee

All Dissertations

Nano-modifiers are typically three orders of magnitude smaller in size than their micro-counterparts. At this scale, interactions between matrix molecules and the nano-modifiers can lead to novel physical and chemical properties of the resulting nanocomposites. Carbon nanofibers (CNFs) are a class of nano-modifiers that has received significant attention recently because they have superior electrical conductivity and mechanical properties with a high aspect ratio (length over diameter). Several recent research studies have focused on enhancing electrical and mechanical performance of composites in the presence of CNFs. However, the influence of CNFs on the structure of the polymer matrix is important in …

Studies In The Biochemistry And Cell Biology Of Trypanosoma Brucei Hexokinases, Jeremy Chambers Dec 2007

Studies In The Biochemistry And Cell Biology Of Trypanosoma Brucei Hexokinases, Jeremy Chambers

All Dissertations

Trypanosoma brucei expresses two hexokinases (TbHK1 and TbHK2) that are 98% identical at the amino acid level. We previously found that recombinant TbHK1 (rTbHK1) has hexokinase activity, while rTbHK2 did not, a finding attributed to differences in the C-termini of the proteins. We found that the C-terminal tails of TbHK contained a novel motif specific for eukaryotic hexokinases found within the final helix of an ATP-binding domain. By altering the residues in the C-terminal tail of TbHK1 to resemble the residues found in TbHK2, we found that D454, F462, M466, and N469 were essential to TbHK1 catalysis. Additionally, we found …

Evaluation Of Human Prolactin, Its Antagonist, And Antagonist-Based Fusion Proteins As Chemopreventative And Therapeutic Agents, Seth Tomblyn Dec 2007

Evaluation Of Human Prolactin, Its Antagonist, And Antagonist-Based Fusion Proteins As Chemopreventative And Therapeutic Agents, Seth Tomblyn

All Dissertations

Cancer is a collection of diseases with many different manifestations and is the second leading cause of death in the United States. Breast cancer accounts for nearly one third of cancer diagnosis in women. Prolactin (PRL) functions as a lactogen and as a mammary gland differentiation factor. PRL acts in an autocrine/paracrine manner within the mammary gland and in breast tumors which implies PRL may be involved in breast cancer progression. This is corroborated by the PRLR over-expression in breast cancer cells lines and the majority of patient biopsies. These reasons make PRL and PRLR attractive targets for breast cancer …

Influence Of Mercury-Dissolved Organic Matter (Dom) Complexation On Toxicity In Natural Waters, Christina Mcnaughton Dec 2007

Influence Of Mercury-Dissolved Organic Matter (Dom) Complexation On Toxicity In Natural Waters, Christina Mcnaughton

All Dissertations

Global industrialization, coupled with a large biogeochemical cycle that moves mercury through the environment, has resulted in higher mercury concentrations being detected in many environmental compartments. Although the presence of mercury in each compartment has the potential to elicit toxicity, mercury found in natural waters provides the greatest risk, due to the various reactions it can undergo, resulting in a plethora of different species.
Due to the fact that mercury contamination in aquatic systems has the potential to bioaccumulate and biomagnify up the food chain and cause toxicity, understanding the behavior of mercury in these systems is imperative in the …

Inclusive dijet and trijet production in deep inelastic ep scattering has been measured for 10 < Q2 < 100 GeV2 and low Bjorken x, 10-4 < xBj < 10-2. The data were taken at the HERA ep collider with centre-of-mass energy sqrt(s) = 318 GeV using the ZEUS detector and correspond to an integrated luminosity of 82 pb-1. Jets were identified in the hadronic centre-of-mass (HCM) frame using the kT cluster algorithm in the longitudinally invariant inclusive mode. Measurements of dijet and trijet differential cross sections are presented as functions of Q2, xBj, jet transverse energy, and jet pseudorapidity. As a further examination of low-xBj dynamics, multi-differential cross sections as functions of the jet correlations in transverse momenta, azimuthal angles, and pseudorapidity are also presented. Calculations at O (αs3) generally describe the trijet data well and improve the description of the dijet data compared to the calculation at O (αs2). © 2007 Elsevier B.V. All rights reserved.

The first observation of (anti)deuterons in deep inelastic scattering at HERA has been made with the ZEUS detector at a centre-of-mass energy of 300-318 GeV using an integrated luminosity of 120 pb-1. The measurement was performed in the central rapidity region for transverse momentum per unit of mass in the range 0.3 < pT / M < 0.7. The particle rates have been extracted and interpreted in terms of the coalescence model. The (anti)deuteron production yield is smaller than the (anti)proton yield by approximately three orders of magnitude, consistent with the world measurements. © 2007 Elsevier B.V.

In-Vitro Investigations On Ultrasonic Control Of Water Chestnut, Meiyin S Wu, J. Wu Dec 2007

In-Vitro Investigations On Ultrasonic Control Of Water Chestnut, Meiyin S Wu, J. Wu

Department of Biology Faculty Scholarship and Creative Works

Water chestnut (Trapa natans L.) is native to southern Europe and tropical Africa and Asia and was first introduced into North America in 1874. Since then, wild populations have quickly become established in many locations in the northeastern United States. T. natans is referred to as a noxious aquatic weed since its aggressive growth usually results in complete coverage of the water surface with floating rosettes of leaves. This study investigated the potential of the ultrasonic control of water chestnut since ultrasound has been documented to effectively damage plant cells and tissues. Various frequencies and amplitudes of ultrasound waves generated …

Predicting The Growth Of Deciduous Tree Species In Response To Water Stress: Fvs-Bgc Model Parameterization, Application And Evaluation, Ying Wang

All Theses

A hybrid model (FVS-BGC) that couples the process-model STAND-BGC to the empirically based forest vegetation simulator (FVS) was parameterized with comprehensive ecophysiological, site, and silvicultural data collected on Acer rubrum L. (A. rubrum), Paulownia elongata (P. elongata), Quercus nuttallii (Q. nuttallii), and Quercus phellos (Q. phellos) in 2006. A series of simulations provided of estimates species-specific carbon gain, growth, and yield under well-watered and water-stressed conditions. Simulations on a species-specific basis allowed assessment of drought effects on stand production and the ability of FVS-BGC to predict on a deciduous species basis. Under well watered conditions, FVS-BGC was able to predict …
