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 ...
Effect of Forest Structure on the Understory Light Environment and Growth Potential of Oak Seedlings in a Closed Canopy Riparian Forest
(2005-12-15)
This research was designed to examine the relationship between the residual structure following low intensity partial cutting regimes and the light characteristics found in a riparian hardwood forest. The relationships ...
Parenting Processes and Risky Sexual Behaviors in First and Second Generation Hispanic Immigrant Youth
(2006-12-15)
Despite the remarkable increase of Hispanic immigrant families with foreign-born and American-born children, the unique problems and behavioral characteristics of this particular population continue to be overlooked. Even ...
Performance of Sugar Maple Taxa (Acer saccharum Marsh.) in North Alabama
(2006-12-15)
A sugar maple (Acer saccharum Marsh.) variety trial was initiated in March, 1999 at the North Alabama Horticulture Substation in Cullman, Ala. (USDA Zone 7). The purpose of the study was to identify superior sugar maple ...
Effective Non-Traditional Weed Control in Container-Grown Nursery Crops
(2006-12-15)
A series of experiments were conducted to evaluate container nursery crop tolerance and oxalis control with postemergence applied diuron as influenced by timely overhead irrigation. Intent was to identify an interval ...
Isolation of Genes from Cold Treated Poncirus trifoliata
(2006-12-15)
Low temperature is one of the most critical environmental factors limiting plant growth and productivity. To survive, plants have developed a complex stress response system for defense against various environmental factors. ...
Stem Cutting Propagation of the Endangered Species, Clematis socialis (Kral)
(2006-12-15)
Clematis socialis (Kral), the Alabama leather flower, is a federally listed endangered species native to NE Alabama and NW Georgia. In addition to conservation and management practices of the few existing populations, ...
Slave Missions and Membership in North Alabama
(2006-12-15)
As white landowners settled the North Alabama towns of Florence, Huntsville, and Tuscaloosa with their slaves, they began to create missions for the religious education of blacks. Many did so out of a desire to share their ...
