Advanced Tools For Characterizing HMA Fatigue Resistance
(2011-02-22)
Accurately and efficiently characterizing the material properties of hot mix
asphalt (HMA) is critical to the design and development of pavements that can
experience repeated loading for long periods of time and resist ...
Analysis of Data from the Barnett Shale with Conventional Statistical and Virtual Intelligence Techniques
(2011-02-22)
Water production is a challenge in production operations because it is generally
costly to produce, treat, and it can hamper hydrocarbon production. This is especially
true for gas wells in unconventional reservoirs like ...
Design of a Surface Albedo Modification Payload for Near Earth Asteroid (NEA) Mitigation
(2011-10-21)
The development of the Surface Albedo Treatment System (SATS) onboard a spacecraft mission to the near earth asteroid (NEA) Apophis in 2012 is an innovative concept of deflecting NEAs from possible impact with the Earth ...
Heterogeneous Reaction of NO2 on Soot Surfaces and the Effect of Soot Aging on its Reactivity Leading to HONO Formation
(2011-02-22)
Soot aerosols are known to be an important atmospheric constituent. The
physical and chemical properties of soot allows it to act as a precursor of gas-surface
heterogeneous reactions, providing active sites for the reduction ...
Reference Radiation for Cosmic Rays in RBE Research
(2011-10-21)
When astronauts travel in space, they are exposed to high energy cosmic radiations. The cosmic ray spectrum contains very high energy particles, generally up to several GeV per nucleon. Currently NASA is funding research ...
A Comparative Study of Kalman Filter Implementations for Relative GPS Navigation
(2011-02-22)
Relative global positioning system (GPS) navigation is currently used for autonomous
rendezvous and docking of two spacecraft as well as formation
flying applications.
GPS receivers deliver measurements to
flight ...
Optimal Control of Perimeter Patrol Using Reinforcement Learning
(2011-08-08)
Unmanned Aerial Vehicles (UAVs) are being used more frequently in surveillance scenarios for both civilian and military applications. One such application addresses
a UAV patrolling a perimeter, where certain stations can ...
The Association of Virulent Vibrio Spp. Bacteria on Gafftopsail and Hardhead Catfish in Galveston Bay
(2011-10-21)
Vibrio vulnificus (Vv) and V. parahaemolyticus (Vp) are gram negative, halophilic bacteria that occur naturally in estuarine waters of Galveston Bay. Both bacteria have the potential to cause infections in humans either ...
On Consistent Mapping in Distributed Environments using Mobile Sensors
(2011-10-21)
The problem of robotic mapping, also known as simultaneous localization and mapping (SLAM), by a mobile agent for large distributed environments is addressed in this dissertation. This has sometimes been referred to as the ...
Effects of Exogenously Applied Indole-3-Acetic Acid (IAA) to Cotton
(2011-08-08)
There is a need in the cotton industry for cultivars with enhanced lint yield potential and high-quality fiber properties. Indole-3-acetic acid (IAA) is a phytohormone that is predominantly responsible for cell elongation ...
