Description
The U.S. Army Research Laboratory (ARL) was tasked to investigate the ballistic performance of aluminum alloy (AA) 5059 to determine if it was a desirable alternate alloy for use as vehicle armor. Current alloys, such as AA5083 and AA7039, have high yield and tensile strengths and provide increased ballistic protection but have significantly less corrosion resistance than AA5059. AA5059 generally provides greater ballistic protection levels than AA5083...

Description
The performance of six different commercially available carbon monofluoride (CFx) materials were evaluated at four different discharge rates. The physical and chemical properties of the CFx materials were correlated to cell performance in lithium coin cells. This study was undertaken to determine if there are specific physical or chemical properties that can be tied to performance and if modification of these properties could lead to an improved carbon...

Description
The present study is part of an ongoing effort to identify objective predictors of subjective air traffic controller workload. The study begins with a comparison of the salient variables governing en route controllers' perceptions of the performance capabilities of a sample of aircraft and the actual performance of the aircraft in the en route environment. A group of 24 Certified Professional Controllers (CPCs) from Kansas City (N= 17) and Boston...

Description
SIGIR found that Wamar successfully completed the three contracts and that JCC-I/A and GRD actively carried out their management and oversight responsibilities, though some management and contract problems affected costs and schedules. The 2004 contract, competitively awarded to Wamar to purchase and deliver armored vehicles (W914NS-04-D-0121), was mostly successful although eight vehicles were stolen and other vehicles were delivered late. Wamar...

Description
A mission program named Extended Area Protection and Survivability was initiated at the U.S. Army Research Laboratory to demonstrate guided ammunition technologies to defend the battle space against any presented targets, such as mortars, rockets, and artillery. This report introduces the first step in the development of the guided ammunition system. It presents high-level physics-based simulations of a 60-mm projectile system. The topology of the...
