Shipboard structures employing composites typically use glass/vinyl ester (VE) manufactured with vacuum assisted RTM. This composite system offers reduced weight, no corrosion and improved signature performance but lacks the fire performance characteristics required for shipboard use. Phenolic resins (PH) provide outstanding fire performance but are difficult to process and offer lower structur ...

The growing reliance on wireless electronic systems presents us with a need for new diversity antennas for civilian and military platforms. These antennas must take account of platform curvature, material treatments and nearby interactions, all of which affect the antenna performance. To support the development and design of these antennas, a new generation of analysis is required which retains ...

This proposal addresses development of a distributed image oriented storage and indexing architecture for building content searchable image databases (containing test, graphics, images, and digitize video). This is particularly difficult because computer vision has yet to solve the shape recognition problem which encompasses both text type and object type entities. Also, since substantial comput ...

Ultrafiltration membranes offer great potential for compact, low cost clean-up of Navy surface ship graywater and blackwater. A major limitation of these ultrafiltration membranes is significant loss in flux with time associated with membrane fouling from proteins, polysaccharides, and other waste products. Backflushing can only be used to a limited extent. Chemical treatments are undesirous si ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...

In spite of their high speed and precision, contemporary computing platforms fail to deliver the computational density required for real- time image processing towards the realization of truly intelligent and autonomous behavior in today's weapons systems and computers. And yet the simplest of living systems are able to perceive and interpret their environment effortlessly, using only a ...

Protecting marine mammals from harm during Navy explosive operations is a high priority. A dedicated sensor system for field mitigation that has a high probability of detection, is flexible and can be tailored to fit the scope of an exercise is highly desirable. A preliminary examination of the characteristics and behavior of marine mammals suggests that a unique dedicated passive acoustic senso ...

The objective of this program is to develop a low cost hydrophone for use in towed line arrays. To this objective, Phase I will identify and develop hydrophone array assemblies using cost-effective hydrophone designs. This will be accomplished through the use of sonobuoy technology as related to design and manufacturability. During Phase I the specification requirements for the array will be d ...
