Shape Memory Alloy Robotic Truss
(2008-09-09)
The development, design, and analysis of a Shape Memory Alloy Robotic Truss (SMART) actuator is presented in this research paper. SMART is a three-degree of freedom actuator capable of large rotary and bending displacements ...
Effect of Coordinate Switching on Simulation Accuracy of Translunar Trajectories
(2008-09-09)
This thesis focuses on the effect of round-off error in the accurate simulation of translunar trajectories. The three-body dynamics can be posed in either an Earth-centered (EC) or Moon-centered (MC) frame. In this study, ...
Invasive Characteristics of Chinese Privet (Ligustrum sinense Lour.) in a Bay Swamp in the Fall Line Hills of East-Central Alabama
(2008-09-09)
Exotic species often become invasive because of an ability to occur in many habitat types with a variety of environmental variables. One species of plant that is particularly invasive throughout the southeastern United ...
Methods for Optimization of a Launch Vehicle for Pressure Fluctuation Levels and Axial Force
(2008-09-09)
A computational fluid dynamics (CFD) code has been combined with a Genetic Algorithm (GA) to perform a shape optimization study on a two dimensional axisymmetric model of a typical launch vehicle. The objective of this ...
Tufted Lovegrass (Eragrostis pectinacea) and Doveweed (Murdannia nudiflora) Control in Warm-Season Turfgrasses.
(2008-09-09)
Tufted lovegrass has been identified as a problem weed in sod production in Mississippi, Tennessee, Arkansas, Georgia and Alabama, particularly in zoysiagrass. The slow growth rate of zoysiagrass is suspected to be a ...
Competition between Domestic and Imported Farmed Fish - A Demand System Analysis
(2008-09-09)
Monthly data from 1999 through 2007 are used to estimate demand interrelationships between domestic and imported farmed fish. Specifically, a demand model is estimated for four products: imported frozen tilapia fillets, ...
Launch Vehicle Performance Enhancement Using Aerodynamic Assist
(2008-09-09)
A complete preliminary design model of a three-stage solid-fuel launch vehicle
has been combined with a genetic algorithm to perform an optimization study with the
goal to enhance performance using aerodynamic assist. ...
Aerodynamic Testing of a Circular Planform Concept Aircraft
(2008-09-09)
Auburn University has entered into collaboration with Geobat Flying Saucer Aviation Inc. for aerodynamic and flow visualization studies of the Geobat aircraft. The aircraft model that was tested consisted of a circular ...
Analysis of Stable Isotopes of Hydrogen to Determine Migrational Source of Silver-Haired Bats (Lasionycteris noctivagans) in Alabama
(2008-09-09)
Signatures of deuterium obtained from claws of 21 silver-haired bats (Lasionycteris noctivagans) were used to estimate the nearest probable pre-migratory location of these bats. For 5 consecutive weekends beginning 28 ...
Yaw-Roll Coupled Oscillations of a Slender Delta Wing
(2008-09-09)
The delta wing has been a highly studied aerial planform, from counter rotating vortices to a rolling `wing rock' motion. The research done at Auburn University is an extension of those studies. This research studies not ...
