In this thesis methods of spoo ng prevention are developed to detect, identify, and
mitigate an attack against both networked and standalone GPS receivers. A network based
detection algorithm is introduced which combines ...
Comparing triploid and diploid growth and mortality in farmed oysters, Crassostrea virginica, in the northern Gulf of Mexico
(2018-02-05)
The significance of the triploid advantage, in terms of growth and survival, varies across studies and environmental conditions. A meta-analysis was performed with 30 studies using chemically induced triploids and triploids ...
Performance of pecan (Carya illinoinensis) cultivars grown in Alabama
(2018-02-01)
Between 1996 and 1999, pecan cultivars were grafted to mature pecan trees at the E.V. Smith Research Center in Shorter, Alabama [E.V. Smith] and Gulf Coast Research and Extension Center in Foley, Alabama [Gulf Coast] in ...
Within-tree Fuel Quality of Loblolly Pine (Pinus taeda)
(2018-01-25)
There is a lack of knowledge in the whole tree’s fuel quality and how that quality might change within the tree or between size classes of trees. A sample set of 20 loblolly pines (5 trees within 4 diameter at breast ...
Effect of Ionic Strength on Cellulose Nanocrystal Dispersion Viscosity and Surface Modification of Thin Film
(2018-01-19)
The primary aim of this research was to explore the effect ionic strength on aqueous cellulose nanocrystal (CNC) dispersions with a range of concentrations spanning isotropic, biphasic, and liquid crystalline regimes. The ...
Assessing Occurrence and Habitat Characteristics of the Southeastern Pocket Gopher (Geomys pinetis)
(2018-01-10)
The southeastern pocket gopher (Geomys pinetis), a species of conservation concern in Florida, Georgia, and Alabama, is of increasing conservation concern due to a range wide decline believed to be due to habitat loss and ...
Development of diets for soft-shell mangrove crabs (Scylla spp)
(2018-01-10)
The objective of this research was to develop practical formulated diets for soft-shell mangrove crab farming. Although the large-scale farming of soft-shell crab has been going for more than 20 years, little research has ...
Deep genetic divergence in the Deep South: An integrative approach to species delimitation reveals the paraphyletic nature of speciation in the trapdoor spider genus Cyclocosmia.
(2018-01-09)
Mygalomorph spiders house an incredible amount of cryptic genetic information, making them an excellent model for species delimitation. An integrative approach to species delimitation uses multiple lines of evidence to ...
Hydrogen Production Via Thermocatalytic Decomposition of Methane Using Carbon Supported Materials
(2018-01-09)
Convectional hydrogen (H2) production process such as steam methane reforming process (SMR) produces massive amounts of CO2 (i.e., 13.7 kg CO2 per kg H2 production). Because of the large amount of CO2 production during the ...
Development of Oligonucleotide, Small Molecule, and Protein Assays using Square-wave Voltammetry with Electrode-bound Nucleic Acid Nanostructures
(2018-01-09)
Biomarker analysis plays a decisive role in health care. This role is not only limited to disease diagnosis, but it also involves understanding of biological and physiological functions in order to monitor health, observe ...
Assessment and Synthetization of Extension Needs Encompassing the Economic and Ecological Impacts of Wild Pigs Among Young Pine Plantations
(2017-12-18)
The southeastern United States has recently seen its first increases in Longleaf pine (Pinus palustris Mill.) acreage after more than four centuries of decline thanks to ongoing restoration efforts. Connecting existing ...
Cyber Security System Dynamic Modeling
(2017-12-15)
Cyber security modeling is the process of creating a normalized view of the cyber security situation. A typical cyber security model has information about the network infrastructure, security settings, and a list of possible ...
Android Malware Detection through Machine Learning on Kernel Task Structure
(2017-12-11)
The popularity of free Android applications has risen rapidly along with the advent of smart phones. This has led to malicious Android apps being involuntarily installed, which violate the user privacy or conduct attack. ...
