The Air Force has demonstrated that a water is capable of extinguishing comparable H2O2 oxidizer fires with 23 pounds of water vs 67 pounds of halon. Recent advances in sensor technology make it possible to detect an H2O2 leak prior to ignition, or to rapidly detect ignition in order to initiate fire protection system water flow. Recent findings by Streamline Automation also indicate that fire e ...

Surreptitious communication through steganography has application in many settings. There are many different techniques for hiding steganographic content and in theory, any file type can serve as a carrier. Most studies in steganalysis have focused on single file types and a few steganographic methods on those file types, representing a limited sample of the population of transmitted data. We pr ...

For Phase I, we propose to investigate the scientific, technical, and commercial merit and feasibility of IR sensors based on nanostructures that are compatible with standard silicon IC technology. In Phases II and III we will integrate these sensors with future generations of cellular neural network (CNN) chips. Specifically, we propose to investigate and develop nanoantennas composed of lithogr ...

Gradient Technology in conjunction with Professor M. Hillmyer of the Department of Chemistry at the University of Minnesota proposed to develop advanced technology to recover and convert the explosive and urethane binder found in plastic bonded explosives. This technology provides a unique reclamation, recovery, and reuse opportunity for dramatically reducing the disposal cost of technology munit ...

This proposal is for the design and development of a challenging, adaptable, and extendible AI system for use in state-of-the-art computer-based wargames. The development will result in a 3rd generation computer wargame based on modern air power conflict and the ability to apply the technology developed for this project in other wargames ranging from tactical ground-based warfare to naval conflic ...

Carbon nanotubes (CNTs) have a promise as building blocks for future materials and devices. This STTR Phase I project will focus on the (University-based) theoretical modeling and assessment of mechanical properties, transfer of this knowledge to NanoTechnologies of Texas, Inc. (NTT) which in turn will concentrate its effort on nanotube synthesis, characterization and improvements of the growth c ...

Nanophotonics promises to have a revolutionary impact on the landscape of photonics technology. Due to the maturity of sub-micron silicon CMOS technology, nanophotonics on silicon is anticipated to play a critical role in future nano-system integration. In this program, we propose an innovative approach to building ultra-compact silicon Mach-Zehnder(MZ) modulators. The proposed structure consists ...

Beryllium (Be) has been the material of choice for many MDA Exoatmospheric Kill Vehicle (EKV) components due to its desirable physical characteristics despite health hazard concerns and its high cost. However, Be/Be alloys have poor radiation shielding properties against x-ray, gamma and space radiation. Lead shielding materials must be used in conjunction with Be/Be alloy materials where radiat ...

Lubrication problems in rolling element bearings are the leading cause of failure in spacecraft momentum/reaction wheels, control moment gyros, gimbals, and similar applications. Condition monitoring technologies developed for terrestrial or aircraft applications are not adequate due to unique spacecraft conditions and the need to prevent rather than just detect damage. Sentient Corporation, in co ...

The feasibility of chemical beam epitaxy to grow ultrahigh quality GaN thin films will be developed. This process will allow the growth of GaN on high thermal conductivity substrates and enable the fabrication of precision superlattice structures. GaN will be grown using Ga effusion cells and ammonia-in an ultrahigh vacuum environment. This growth rate will be in the 1 micron per hour range at tem ...
