Oligotrophication Effects Following Diversion of Waste Effluent from an Embayment of Lake Martin, Alabama
(2006-12-15)
I examined the effects of nutrient diversion on water quality, phytoplankton, and macroinvertebrate and fish community structures over a 10-year period in Lake Martin, Alabama. In 2001, a pipeline began diverting treated ...
Evolution of Signal Divergence and Behavior in Cyprinella galactura, the whitetail shiner
(2006-12-15)
Acoustic signaling in anurans, insects, birds, and mammals has played an important role as an interspecific isolating mechanism and is also believed to be a mechanism of sexual selection in intraspecific mate choice. A ...
Effects of hydrologic variation on dynamics of channel catfish and flathead catfish populations in regulated and unregulated rivers in the southeast USA
(2006-12-15)
Altered flow regimes resulting from dam construction can have negative impacts on growth and recruitment of fishes in regulated river systems. The effects of hydrologic variation on channel catfish Ictalurus punctatus and ...
A Comparative Study of the Immunological Properties of Extracellular Products Between Virulent and Less Virulent Edwardsiella tarda
(2006-12-15)
The immunological properties of the extracellular products (ECP) of the Edwardsiella tarda parent FL6-60 and mutant RET-04 isolates were investigated in Nile tilapia Oreochromis niloticus. Non-purified ECP derived from ...
Studies on Cercospora Leaf Spot
(2006-12-15)
Fresh Pseudocercospora cornicola specimens were compared to an isotype specimen to confirm species identity. The two specimens proved to be the same taxonomic entity. The fungus was then redescribed and illustrated from ...
Assessing Soil Microbial Populations and Activity Following the Use of Microbial Inoculants: Effects on Disease Suppressiveness and Soil Health
(2006-12-15)
In recent years, assessing use of microbial inoculants for promotion of plant growth has increased. Optimizing application frequency of PGPR is critical to achieving the maximum benefit from this technology. The study ...
Language acquisition of same-sex, multiple-birth siblings: A nature/nurture study
(2006-12-15)
This retrospective study considers the extent to which nature and nurture influence early first language acquisition. Data sets that address rate of grammatical acquisition, acquisition of regional dialect features, and ...
Ad-hoc and Multi-hop Wireless Sensor Networks for Activity Capture in Cooperative Robotics
(2006-12-15)
Cooperative robotics has been the focus of attention of various groups in recent years. The idea of using a team of robots instead of a single one to execute a task came from the necessity of accomplishing a task that is ...
Design and Development of a GPS Intermediate Frequency and IMU Data Acquisition System for Advanced Integrated Architectures
(2006-12-15)
Advanced levels of GPS and INS integration, including Deeply Integrated and Ultra-
Tightly Coupled, have been reported to provide significant gains in anti-jamming capa-
bility and reduced susceptibility to loss of GPS ...
Weak Signal Reception Using Software Defined Radios and a Two-Element Antenna Array
(2006-12-15)
Software Defined Radio (SDR) is a quickly emerging technology. SDR removes
the signal processing task from the analog hardware portion of a radio and places it into
the Digital Signal Processing (DSP) domain. Many ...
Experimental and Theoretical Investigation of Contact Resistance and Reliability of Lateral Contact Type Ohmic MEMS Relays
(2006-12-15)
In this thesis, the reliability of electrostatically actuated ohmic contact type MEMS relays has been investigated. Multi-contact MEMS relays using electrostatic comb-drive actuators have been used in this study. The ...
Kalman Filter Based Tracking Algorithms For Software GPS Receivers
(2006-12-15)
In this thesis several new Kalman filter based tracking algorithms for GPS software
receivers are presented. Traditional receivers use Costas loops and Delay Lock Loops
(DLL) to track the carrier and Pseudo-Random Noise ...
CMOS Stress Sensor Circuits
(2006-12-15)
Two CMOS piezoresistive stress sensor circuits based on piezoresistive MOSFETs (PiFETs) are the focus of this dissertation. The first design is a multiplexed array of 512 piezoresistive sensors fabricated on a 2.2 by 2.2mm2 ...
Tag line tracking and Cardiac Motion Modeling from Tagged MRI
(2006-12-15)
Magnetic resonance (MR) tagging magnetically labels specified regions of the myocardium, which appear in the MR images with a spatially encoded pattern of dark stripes called tag lines. The deformation of these tag lines ...
High Frequency Noise Modeling and Microscopic Noise Simulation for SiGe HBT and RF CMOS
(2006-12-15)
RF bipolar and CMOS are both important in RFIC applications. Modeling of noise provides
critical information in the design of RF circuits. Unfortunately, available compact models
for both RF bipolar and CMOS, are typically ...
The Effectiveness of DIBELS Oral Reading Fluency as a Predictor of Reading Comprehension for High- and Low-Income Students
(2005-08-15)
The purpose of this two-part, non-experimental study was to examine the predictive nature of reading fluency scores in relation to reading comprehension scores and determine if the associations between these scores were ...
Guidelines To Develop Product Forms From Chinese Calligraphy
(2005-12-15)
“Global Westernization” is the most prominent characteristic of the 20th century. World culture, design and art form lean towards the West. Western products, like German products can be seen in markets all over the world. ...
Creating Spatial Probability Distributions for Longleaf Pine Ecosystems Across East Mississippi, Alabama, the Panhandle of Florida, and West Georgia
(2005-12-15)
Longleaf ecosystems have severely decreased in total area since pre-European settlement. These dramatic losses are the principle reason for the listing of many plants and animals as endangered, and have been the driving ...
