21st Century Technologies’ (21CT) ACCESS (Automated Comparison and Clustering of Entity SignatureS) research effort addresses the issue of comparing entities such as human personas and networks, so that a more complete assessment of at-risk entities can be made within and across the various domains in which those entities interact. The Phase I effort of ACCESS will provide an effective similarit ...

The overall goal of the proposed research effort is the development of APICS - an Adaptive Platform-Independent Control System for launch and recovery of submersible remotely operated vehicles (ROVs). APICS will operate in constant tension mode during launch and recovery and also in active heave compensation mode to maintain constant ROV depth is a seaway. Barron Associates, Inc. and its research ...

Aurora Flight Sciences and MIT propose to develop a model-based adaptive health estimation and real-time proactive control to identify gas turbine engine stability risks and avoid them through control action. In this concept, the engine control system actively monitors sensors and actuators, compares them against physical models, and infers which components may be performing poorly and may need to ...

Friction stir welding (FSW) can produce stronger, lighter, and more efficient welds than any previous process. In aluminum assemblies, FSW provides improved joint strength, fatigue properties and crack resistance compared to conventional arc welded joints. One of the current barriers to widespread use of FSW is that the process generally requires the use of clamping systems that are often cumberso ...

Numerical methods have proved to be very successful in low and mid frequency (VHF/UHF) regimes. Although these methods are based on rigorous integral or partial differential equation formulations, they cannot presently solve electrically large problems of EM radiation pattern and coupling prediction associated with antennas on aircraft at higher frequencies (S/X/Ku/Ka bands). On the other hand, as ...

We propose to develop an advanced breakwater and causeway system for operation in austere ports, with limited or no facilities, that will provide a complete solution to reliably enable the military to supply forces ashore with needed cargo and supplies. A ruggedly-designed breakwater made from high-strength fabrics can yield an area of reduced sea state conditions in which cargo transfer operation ...

Currently, communicating to submarines at sea requires either large, low-frequency, land-based systems or for the submarine to be near the surface towing an antenna or loitering near a communications buoy. GMS’s proprietary (US Patent Application 12/219,569 -24 July 2008) wavelength compression antenna (WCA) technology overcomes these limitations by efficiently transmitting a low frequency signa ...

Since the beginning of Naval Warfare, effective communications with the submarine platform has been a significant challenge. By its very nature, submarine warfare succeeds or fails based upon the stealth abilities of the platform. Covert communications at speed and depth are required to fully engage the platform but providing this capability continues to be challenging. Recent efforts to achieve s ...

The primary objective of this Phase II SBIR program would be the continued development of materials for high temperature supersonic flight, designs for low profile, structurally robust conformal antennas and techniques for more rapid, cost-effective and manufacturable fabrication of antennas for aircraft, missiles and other Navy platforms. To accomplish this task, NanoSonic is staffed with a uniqu ...
