Flexural Response of Syntactic Foam Core Sandwich Structures: Effects of Graded Face Sheets and Interpenetrating Phase Composite Foam Core
(2011-05-09)
In this thesis, flexural responses of sandwich structures with different syntactic foam core architectures are studied. The syntactic foam core is made by dispersing hollow glass microballoons in epoxy matrix at different ...
Changes in Southern Piedmont Grassland Community Structure and Nutritive Quality Under Future Climate Predictions: Tropospheric Ozone and Altered Rainfall
(2011-05-19)
Tropospheric (ground-level) ozone (O3) is the most significant phytotoxic air pollutant in the United States. It is readily transported to rural agricultural and forested areas from urban centers. Estimating the effects ...
An Examination of Teacher Working Conditions in Alabama Middle Schools
(2011-05-09)
The purpose of this study was to determine what relationships, if any, exist between how Alabama middle school teacher perception of their principals affect student achievement and teacher attrition. Peer comparisons ...
Genetic Resistance to Reniform Nematode (Rotylenchulus reniformis) in Upland Cotton (Gossypium hirsutum)
(2011-05-09)
Reniform nematode, Rotylenchulus reniformis Linford & Oliveira, is one of the most destructive nematode pests of cotton (Gossypium spp.), and upland cotton (G. hirsutum L.), the most common cultivated type, is lacking in ...
Application of Mobility Models to Collaborative Search and Rescue Robotics
(2011-05-26)
This thesis addresses the challenges of using small, low-cost robotic nodes with limited processing capabilities in collaborative search and rescue. Mobility models tailored specifically to the mobility patterns of such ...
A Non-contact Method for Sensing Tire Contact Patch Deformation Using a Monocular Vision System and Speckled Image Tracking
(2011-05-16)
A full-field, non-contact deformation sensing system was developed with an application for tires. Using an image tracking algorithm, in-plane displacements and their gradients were calculated. Furthermore, the effects of ...
Development of Wireless Magnetoresistive Sensor Network for Unexploded Ordnance and Landmine Detection
(2011-05-06)
This thesis summarizes the effort toward developing a passive/active magnetoresistive (MR) sensor array for unexploded ordnance (UXO) realized with wireless sensor network technology. In recent years, the rapid development ...
Econometric Analysis of Household Energy Consumption in the United States, 2006 and 2008
(2011-05-18)
Household expenditures on electricity and gasoline account for a very large share of household budget in the United States. Considering the upward trend in energy price during recent years, this study investigated U.S. ...
Rooting Evaluation of Kiwifruit (Actinidia chinesis) and Effects of Anaerobiosis on Bud Break
(2011-05-05)
Two unrelated studies were conducted in completion of this degree. The first study evaluated different rates of growth hormone on softwood kiwifruit (Actinidia chinensis) cuttings to determine the proper rate for optimal ...
Response of Resistant Pepper Varieties to Viruses in the Genus Potyvirus
(2011-05-18)
Potyviruses are a persistent threat to bell pepper (Capsicum annuum L.) production worldwide. We have expended much effort to study the resistance response of pepper cultivars at cellular and whole plant levels. To evaluate ...
