A new hybrid model will be developed under this Phase II effort predicting the propagation of transient bursts at high-altitudes that can be used to design and evaluate flux-based discrimination concepts. The hybrid model has 3D continuum (CRAFT CFD® Code), DSMC (DAC97 Code), and free molecular components and performs the complete analysis from burst source to farfield, interfacing solutions alon ...

New Counter-Counter Measure (CCM) techniques are proposed for Missile Defense (MD) which can provide discrimination of balloons and possibly other decoys in the presence of a Re-entry Vehicle (RV). This will be accomplished by the utilization of new advanced materials and concepts manufacturing and deployment technologies unique to General Sciences, Inc. (GSI), and its subcontractor Miltec. It i ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

We investigate the development of a secure fuselet runtime environment built on a foundation of aspect-oriented web services. Aspect-oriented techniques enable the modularization of crosscutting concerns such as remote access, security, and monitoring using code instrumentation. We compose aspect-oriented instrumentation with web service technologies in a noninvasive and orthogonal manner, and lev ...

Advanced space-borne infrared detectors require cooling at temperatures near 10 K. Cooling loads for these detectors will range from 0.25 W to 1.0 W at 10 K, with additional loads at higher temperatures. A multistage cooler, capable of cooling multiple loads, will offer large potential gains in system efficiency and weight. Turbomachine-based Brayton cryocoolers are ideal candidates for these m ...

Effective collective protection fabrics must have a reliable closure system. During our Phase I Work Plan, Sigma-K began developing a Hermetic Textile Closure Hardware (HATCH) system. The HATCH combines both a magnetic and geometric self locking mechanism that will provide a hermetic seal when closed. Our current Phase I successes include developing self closing samples that can provide a hermetic ...

The projected cost for the Mentis Sciences, Inc., (MSI) prototype PAC3 radome is 1/6th of the total cost of the present system. A Pareto analysis of the current MSI process indicates that the two largest costs in radome production are the direct labor associated with fabrication and the cost of the raw materials. In Phase I MSI demonstrated that COTS paint spraying technology reduced the direct ...

Solid State Scientific Corporation proposes an triangular barrier photodiode (TBPD) detector for use on a dual mode sensor. The TBPD will function as a passive low-light visible-SWIR imager at long range and as a 3-D LADAR sensor at short range. The TBPD has the advantage of increased optical gain with decreased incident power, making it very attractive for applications with weak target signals, ...

LIQUIDS RELEASED INTO SPACE OFFER HIGH POTENTIAL AS COUNTERMEASURE AGAINST SDI DEFENSIVE SYSTEMS DESIGNED TO ENGAGE BALLISTIC MISSILES DURING THEIR EXOATMOSPHERIC FLIGHT PHASES. THE COUNTERMEASURE POTENTIAL INCLUDES THE ABILITY TO THWART DETECTION AND DISCRIMINATION SYSTEMS, REDUCE DEW EFFECTIVENESS, AND DEFEAT KEW ATTACK. STREAMS AND SPRAYS OF SELECT LIQUIDS WOULD BE USED TO MASK THE DEPLOYMENT O ...
