In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

This project team will fully develop and test AlphaBear 2, a vocabulary learning game for grade 4 to 7 students. Vocabulary is a prerequisite for academic success, as it is linked to stronger performance across academic subjects and improved reading comprehension. It is more difficult for students to participate in educational activities without understanding the key vocabulary associated with tha ...

THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP A HIGH-ACCURACY, HIGHRANGE PRESSURE AND TEMPERATURE TRANSDUCER FOR THE MEASUREMENT OF RAPID TRANSIENTS TO 700 MPA AND TEMPERATURES TO 3000 K, AS WELL AS HEAT TRANSFER, IN GUN INTERIORS. ALL THREE MEASURING FUNCTIONS WILL BE PERFORMED BY ONE SMALL (ABOUT 20 MM IN DIAMENTER) SENSOR UNIT AND SOME EXTERNAL TEMPERATURE SENSORS. THE PRESSURE IS DETECTED BY CA ...

The extended short wavelength infrared (e-SWIR) wavelength band is in a performance gap for infrared detectors. At both shorter and longer wavelengths high performance detector technologies exist: SWIR InGaAs detectors (1.7 m cutoff), and MWIR (3-5 m cutoff) detectors such as InAs-based and GaSb-based Unipolar Barriers, MCT, and InSb. This program proposes development of high performance e-SWIR de ...

A STUDY IS PROPOSED TO DETERMINE THE FEASIBILITY OF A NEW MEASUREMENT SYSTEM FOR DETERMINATION OF RADIOACTIVE CONTAMINATION IN WATER UNDER BATTLEFIELD CONDITIONS. THE PROPOSED SYSTEM HAS THE ADVANTAGES OF AN EASY TO USE, LIGHTWEIGHT, COMPACT, AND RUGGEDIZED MONITORING SYSTEM FOR DIRECT MEASUREMENT OF FISSION PRODUCT CONTAMINATION IN WATER. IT IS ANTICIPATED THAT THE SYSTEM WILL BE CAPABLE OF DETEC ...

Solid oxide fuel cells have long suffered from degradation due to impurities in the fuel and complexities associated with dissimilar materials and high operating temperatures.This degradation lowers the usable cell power output and requires ancillary equipment for fuel sulfur removal and reformation.A unique microstructure for the tubular anode will be produced using a novel freeze-casting techniq ...

THE INCREASING TEMPO AND LETHALITY OF THE MODERN BATTLEFIELD DICTATE THAT THE ARMY'S DISPERSED, SEMI-AUTONOMOUS UNITS AND SYSTEMS POSSESS THE CAPABILITY TO DEFEND THEMSELVES INTELLIGENTLY ON THE BATTLEFIELD BY HAVING EFFECTIVE C2 SYSTEMS WHICH ASSISTS IN INTEGRATING THE DEFENSES FOR WEAPONS PLATFORMS. THE US ARMY FIELD ARTILLERY ENVISIONS THE DISPERSED, SEMI-AUTONOMOUS OPERATION OF WEAPONS SYSTEMS ...

SCATTER FROM GROUND-BASED LASER PORTS (WEAPONS, COMMUNICATION SYSTEMS, RANGE FINDERS) CAN BE LARGE ENOUGH THAT THE LASER LOCATION MAY BE DETERMINED BY DETECTORS POSITIONED WELL AWAY FROM THE BEAM. PORT SCATTER CAN BE REDUCED, BUT NOT ELIMINATED, THROUGH THE USE OF BAFFLES TO LIMIT DIRECT VIEWING OF THE LASER OPTICS. THIS DOCUMENT PROPOSES DEVELOPING A METHOD TO PREDICT THE SCATTER SIGNAL FROM LASE ...

Traditional weapon systems often fail to meet the requirements of close combat typical of the previously discussed engagement, where insurgents often blend in or store weapon amongst friendly or non-combatant forces, to shield them from precision strike munitions of a technologically superior force. This type of warfare has led to an increased focus on the use of less-lethal weapons, to reduce let ...

The purpose of our Phase II effort is to solidify the information architecture and design concepts of the DimSum Framework into a fully-functioning, open-source toolkit. This toolkit will be ready to use (and validated with several small proof-of-concept applications) for software development efforts that enable the Army to cost-effectively build cross-device user interfaces. The framework is stro ...
