This project will investigate candidate space-time coding schemes to be incorporated in a multiple-input multiple output two-way communication system that operates within an urban warfare environment. The main objective is to increase channel capacity to achieve high-quality video transmission using narrow signal bandwidths, typically deployed for voice channels. The investigation will determine t ...

Advanced Cooling Technologies, Inc. (ACT), in partnership with the University of Nevada-Reno (UNR), is developing a high performance metal hydride heat storage and dissipation technology for high power lasers. The proposed technology incorporates heat pipes for passive acquisition and dissipation of high heat flux heat loads and metal hydrides for storage of the heat loads during the laser operati ...

The objective of this proposal is to demonstrate the feasibility of producing exchange-coupled magnets with a mixture of Sm2Fe17Nx and alpha double prime-iron nitride powders as starting materials. Advanced Materials Corporation (AMC), together with Georgia Institute of Technology propose to produce these powders with the use of a fluidized bed reactor and consolidate mixtures of these powders uti ...

The rapid increase in the use of the Internet in many aspects of our lives has led to an explosive growth in the spread of malware such as computer worms, viruses, and trojans. Security tools typically examine software for the presence of malware either by looking for specific byte signatures, or (more recently) by analyzing the candidate binary’s internal logic. However, it is surprisingly easy ...

We propose to examine the necessary ingredients for the development of marketable codes which will: model the morphology of heterogeneous propellants (a packing code); calculate the thermal and mechancial properties of such a morphology or pack; simulate the combustion of the pack; predict the statistics of aluminum agglomeration on the burning pack surface; simulate the flight of these agglomera ...

Laser Induced Breakdown Spectroscopy (LIBS) is being successfully transitioned to field applications in both close-contact (proximity) and standoff detection modes. LIBS is attractive since it can be used to detect a wide range of chemical, biological and explosive (CBE) hazardous materials. While LIBS is well suited to evaluation of complex hazards, including improvised explosive devices (IEDs) ...

Self-healing composites and adhesives would alleviate longstanding problems in aerospace structures associated with multiple types of damage mechanisms such as mechanical/thermal fatigue, microcracking, and debonding. A composite cryogenic tank based on self-healing technology would prevent leakage by sealing microcracks throughout the lifetime of the tank and enable the use of composites in this ...

We aim to construct litmus paper-like colorimetric sensors for detection and quantification of chemical and biological agents in water by performing combinatorial selection of DNA aptamers for cyanobacteria toxins such as microcystins and saxitoxins. Aptamers are single stranded DNA that can bind target molecules with high affinity and specificity. Such DNA aptamers are biocompatible, biodegradabl ...

The main goal of the proposed program is to develop Sm2Fe17Nx/Fe16N2 high performance bulk nanocomposite magnets with maximum energy product approaching 100 MGOe. The proposed study includes: (1) Development of Sm2Fe17Nx single-phase powder with superior magnetic properties; (2) Development of Ti-stabilized Fe16N2 nanoparticles; (3) Development of nanocrystalline composite hard magnetic materials ...

MWIR avalanche photodetectors (APDs) are required in modern Air Force weapons systems to detect, recognize and track stationary and mobile targets under various atmospheric conditions against complex backgrounds. Theoretical and experimental results point toward HgCdTe as the material of choice for fabricating these devices, due to its low ratio of impact ionization coefficients. In Phase I we per ...
