Evaluation of High-intensity and Low-intensity Preconditioning Systems
(2012-02-14)
Steer calves n = 345 (year 1 n = 183; 253 ± 35 kg, year 2 n = 162; 241 ± 36 kg initial BW) were used to evaluate 56-d preconditioning systems in each of two years. Angus- and Charolais-sired calves out of crossbred dams ...
Robust Condition Monitoring and Fault Diagnosis of Variable Speed Induction Motor Drives
(2012-02-14)
The main types of faults studied in the literature are commonly categorized as
electrical faults and mechanical faults. In addition to well known faults, the performance
of a diagnostic algorithm and its operational ...
Characterization of Nanoscale Reinforced Polymer Composites as Active Materials
(2012-02-14)
Single walled carbon nanotube (SWNT)-based polymer nanocomposites have generated a lot of interest as potential multifunctional materials due to the exceptional physical properties of SWNTs. To date, investigations into ...
Learning Usability Assessment Models for Web Sites
(2012-02-14)
This research explores an approach to learning types of usability concerns
considered useful for the management of Web sites and to identifying usability concerns
based on these learned models. By having one or more Web ...
High Resolution Ion Mobility Spectrometry with Increased Ion Transmission: Exploring the Analytical Utility of Periodic-Focusing DC Ion Guide Drift Cells
(2012-02-14)
Drift tube ion mobility spectrometry (IMS) is a powerful, post-ionization separation that yields structural information of ions through an ion-neutral collision cross section. The ion-neutral collision cross section is ...
A Weighted Residual Framework for Formulation and Analysis of Direct Transcription Methods for Optimal Control
(2012-02-14)
In the past three decades, numerous methods have been proposed to transcribe optimal control problems (OCP) into nonlinear programming problems (NLP). In this dissertation work, a unifying weighted residual framework is ...
Effect of Intensive Agriculture on Small Mammal Communities in and Adjacent to Conservation Areas in Swaziland
(2012-02-14)
I examined the effect of sugarcane plantations on small mammal communities at
3 sites in the Lowveld of Swaziland during the dry and wet seasons of 2008. I evaluated
changes in species abundance and community parameters ...
Dynamic Fracture Toughness of Polymer Composites
(2012-02-14)
Polymer composites are engineered materials widely being used and yet not completely understood for their dynamic response. It is important to fully characterize material properties before using them for applications in ...
Patterns of Identification: The Children of Latino/Non-Latino White Families
(2012-02-14)
This thesis examines the various factors that influence how children in
Latino/non-Latino white households are racially and ethnically identified. The question
of multiracial/ethnic identity has come to prominence following ...
Phenotype Analysis of Tobacco Lines Expressing a Deregulated Arabidopsis Ca-ATPase (ACA2)
(2012-02-14)
Functional foods go beyond simply supplying nutrients and are increasingly
becoming a focus in the prevention and treatment of disease; however, the benefits of
biofortified crops to human nutrition have not been well ...
