Fault Detection in Dynamic Systems Using the Largest Lyapunov Exponent
(2012-10-19)
A complete method for calculating the largest Lyapunov exponent is developed in this thesis. For phase space reconstruction, a time delay estimator based on the average mutual information is discussed first. Then, embedding ...
FDTD Analysis of Metamaterial Coated Microwave Antenna
(2011-08-08)
Due to the growth in mobile wireless systems, electrically small antennas (ESAs) which are efficient and have significant bandwidth are in great demand. But these requirements are contradictory. ESAs are known to be highly ...
Performance Evaluation of a Multi-Port DC-DC Current Source Converter for High Power Applications
(2011-08-08)
With the ever-growing developments of sustainable energy sources such as fuel
cells, photovoltaics, and other distributed generation, the need for a reliable power
conversion system that interfaces these sources is in ...
Predicting Forage Nutritive Value Using an In Vitro Gas Production Technique and Dry Matter Intake of Grazing Animals Using n-Alkanes
(2011-08-08)
In the first experiment, forage samples (n = 39) were collected during 4 years (2006
? 2009) from pastures grazed by Santa Gertrudis cattle at the King Ranch, TX. The in vitro
gas production technique (IVGP) was performed ...
Enhancement of the Response Range and Longevity of Microparticle-based Glucose Sensors
(2011-08-08)
Luminescent microspheres encapsulating glucose oxidase and an oxygensensitive
lumophore have recently been reported as potential implantable sensors for in
vivo glucose monitoring. However, there are two main issues that ...
Analysis of the Reactor Cavity Cooling System for Very High Temperature Gas-cooled Reactors Using Computational Fluid Dynamics Tools
(2011-08-08)
The design of passive heat removal systems is one of the main concerns for the modular Very High Temperature Gas-Cooled Reactors (VHTR) vessel cavity. The Reactor Cavity Cooling System (RCCS) is an important heat removal ...
Investigation on Gas-phase Structures of Biomolecules Using Ion Mobility-mass Spectrometry
(2011-08-08)
IM-MS is a 2-D technique which provides separations based on ion shape (ion-neutral collision cross-section, Ω) and mass (m/z ratio). Ion structures can be deduced from the measured collision cross-section (Ωmeas) by ...
The Cross-linguistic Morphological Awareness Transfer: The Development of Chinese-speaking Adolescent Learners' English Morphological Awareness
(2011-08-08)
Cross-linguistic transfer has been found to exist, at different degrees, in the process of second/foreign language acquisition. Both the level of orthographic depth and the orthographic distance between L1 and L2 affect ...
Scaffolding in Technology-Enhanced Science Education
(2011-08-08)
This dissertation focuses on the effectiveness of scaffolding in technology-enhanced science learning environments, and specifically the relative merits of computer- and teacher-based scaffolding in science inquiry. ...
Moisture Diffusion in Asphalt Binders and Fine Aggregate Mixtures
(2011-08-08)
Moisture damage in asphalt mixtures is a complex phenomenon that involves mechanical,
chemical, physical and thermodynamic processes. This damage contributes significantly to the
premature deterioration of asphalt pavements, ...
