There is need for fast, easy-to-operate, and low-risk methods for mapping geography, velocity, and bathymetry of rivers. River charts can be nonexistent or inadequate because of changes in water volume, tides, sediment transport, flooding, and other events. This is a hindrance and a hazard for navigation and other operations. Currently, procedures to map rivers involve navigating surface vessels i ...

Advances in electronically controlled injection technologies for diesel engines have provided a method to improve medium- to heavy-duty engine performance through increased injection pressures, multiple injections, and injection rate shaping. Although these injection systems have been primarily limited to larger engines, the ability to rapidly and precisely meter fuel for smaller engines is partic ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...

A team consisting of Spectral Sciences Inc., Boston University, Boston University Medical School, Radcliffe Consulting and Brighton Consulting will collaborate to develop and validate a novel optical device for the monitoring and evaluation of blood coagulation. In this proposal we describe a novel optical blood coagulation monitoring instrument. The instrument has no moving parts, uses very small ...

In this STTR program, Photonic Systems Inc. and Prof. Jacob Khurgin at Johns Hopkins University propose novel optical external and internal fiber cooling approaches to efficiently cool the high power GaN microwave amplifier. The external cooler is a single end, square-shape, Yb:ZLAN fiber with high reflection (HR) coated surface which can attach to the amplifier surface and create a cold spot at t ...

Future naval operations are expected to make extensive use of unmanned vehicles to support a range of operations, including intelligence gathering, mine warfare, force protection, and anti-submarine warfare. Current unmanned systems are typically controlled remotely by an operator who directly manipulates a control interface for the vehicle. The effectiveness of this approach is obviously limited ...

The proposed Automated Linguistic Analysis Revealing Misrepresentation and Messaging (ALARMM) system significantly advances the state of the art in detecting deception in unstructured data such as Web sites and chat messages. Our research focuses on automated techniques based on linguistic theory that can detect both misrepresentations and hidden messages. The proposed work draws on the field of s ...

This NAVY Small Business Technology Transfer project is directed toward the development of a novel hydrogen generator that employs nanostructured metal foam catalysts. Special coating and form factor will also be employed to the hydrogen generating materials to ensure the safety of storage and transportation, while maintaining very high packing density compared with conventional powder packing.

The implementation of structural health monitoring (SHM) systems into naval applications has been hindered due to component quantity, including sensors, power/communication cables, and acquisition/computation units, as well as data quality. Particularly for large-area applications such ship hulls, complexity of implied system infrastructure can be impractical, and data can be worthless with attenu ...

SI2 Technologies, Inc. (SI2) proposes an innovative solution to the Navy’s need for wideband antennas to support naval ships and Marine Corps’ vehicle communications, electronic warfare (EW), and radar functions. SI2 will develop efficient, broadband, metamaterial antennas for operation in the VHF-UHF frequency range. These antennas will initially be designed for integration with the composite ...
