"21st Century Systems, Inc. (21CSI) proposes to continue its research and realization of an agent-based decision support system, EXLOG21, for logistics and maintenance operations. In Phase I we researched the base theoretical underpinnings for expeditionarylogistics and constructed a convincing autonomic logistics (AL) system prototype (interfaced to a notionally simulated subset of an instrumente ...

"Adequate hearing protection for U.S. Navy crew personnel is mandatory and may be achieved through the use of earcups, earplugs, or both. Donning only the earcups or only the earplugs is referred to as single hearing protection (SHP), while the use ofearplugs under earcups is called double hearing protection (DHP). This Phase I program offers a comprehensive engineering study and design strategy ...

"The extreme noise fields encountered by U.S. Navy flight deck and cockpit crewmen interfere with speech intelligibility and cause hearing loss to warfighter personnel, even with the currently-fielded communication systems. This Phase I program willdevelop new active noise reduction (ANR) technologies and improve existing passive technologies for incorporation into a prototype double hearing prot ...

"The Patuxent River Naval Air Warfare Center (Aircraft Division)is working towards the completion of a personal double hearingprotection (DHP) communication system for use in extreme noiseenvironments. This Phase II program has been designed to finishthe identification of best-possible performance for DHPcommunication systems, followed by successful prototyping of asystem that will be available f ...

"Under Phase I array-processing techniques were developed andanalyzed which provided an effective interference rejectioncapability for acoustic intercept systems. This was demonstratedvia computer analysis and simulation of these techniques asapplied to a volumetric acoustic intercept sensor. It was shownthat, using such an array, an adaptive spatial normalizationtechnique could be used to suppr ...

"The current state of the art for roll-on/roll-off ships (RO/RO) transfer in the stream is sea state 3 (winds up to 16 knots and waves up to 5 feet), and many ramps are not certified for these conditions. This proposal includes a conceptual design for aRO/RO Cargo Transfer system between two freely floating vessels in the stream in sea states up to state 5. This Cargo Transfer design allows for ...

"This proposal addresses development of a new generation of ropes based on advances in fibers, protective materials and manufacturing. These ropes must be as strong and stiff in tension as current wire ropes, yet be much lighter and more flexible. Newmaterials must be resistant to abrasion, wear, creep, and thermal degradation. Phase I will focus on an initial study to identify economically via ...

"With the achievement of 2.1 kW CW I R operation and an upgrade to10 kW in progress, free-electron lasers (FEL) are now a serious option for high-power, military and commercial applications. As specifically identified in the recent "Department of DefenseLaser Master Plan", the key technology issue on the path to high-power FEL deployment is the demonstration of reliable, high-brightness, photocat ...
