Military network environments will be subject to both internal and external threats for the foreseeable future. Internal threats to cyber networks from U.S. personnel receive little attention in comparison to external threats; yet, the consequences can be even more devastating. The lack of tools for understanding insider threat, analyzing risk mitigation alternatives, and communicating results e ...

Determining the scattering properties of small boats on a rough sea surface is a problem of high importance to the Navy. The resulting simulations require large amounts of compute time and mechanisms are sought to accelerate them. The demand for highly realistic graphics has pushed graphics processing units (GPU) on video cards to the point where they easily outperform general purpose processors f ...

Navy aircraft is equipped with an On-Board Oxygen Generation System (OBOGS) to supply the pilot and the crew with supplemental oxygen for high altitude operation. However, Navy aircraft are usually closely spaced while waiting for take-off from aircraft carriers, and the jet engine exhaust contaminates the bleed air used to supply oxygen to the pilot and crew. Among the contaminants in the engine ...

This is a proposal to determine the technical feasibility of a system capable of separating and localizing intermixed sounds in an auditory scene. Our approach will be to design and develop a computational auditory model that overcomes the inherent theoretical limits of the classic Fourier-based model. Phase I effort will produce a requirements specification and design documentation for the lower ...

The Phase I research project will develop a bio-inspired acoustic source separation, localization and tracking algorithm called PreservEar. Separation of speech signals from an auditory scene, often referred to as the cocktail party problem, has been studied for decades. Current source separation solutions suffer from six major problems: (1) source localization and tracking is not very robust; (2) ...

THE PROPOSED WORK AIMS TO DEVELOP OPTOELECTRONIC IMAGE PROCESSING DEVICES THAT INTEGRATE PHOTODETECTORS AND LIGHT MODULATORS INTO LARGE ARRAYS OF "SMART" PIXELS. THESE DEVICES EXPLOIT A HYBRID OPTOELECTRONIC TECHNOLOGY THAT PLACES FAST FERROELECTRIC LIQUID CRYSTAL (FLC) LIGHT MODULATORS DIRECTLY ATOP VERSATILE SILICON VLSI CIRCUITRY. THE DEVICES NOW PROPOSED WILL INCORPORATE MULTIPLE PHOTODETECTOR ...

The U.S. Air Force has significant interest in the development of adaptive structures for micro munition platforms.  However, power, mass and cost constraints significantly limits the applicability of existing adaptive structure concepts for these smaller platforms.  To address these challenges, CTD is proposing the use of solid-state, electrically-driven actuators that require minimal power and ...

n the highly dynamic submarine environment, the Officer of the Deck is the individual primarily responsible for the safety of the ship, subject to orders from the commanding officer (OPNAVINST 3120.32). Key to the officer of the deck’s success is the development of adaptive decision making skills, supporting monitoring, assessment, and problem solving when faced with cognitively challenging si ...

Through this program, FIRST RF will apply a proprietary antenna technology already in qualification for a specific Low Observable (LO) weapons system. This technology promises to dramatically reduce the cost and complexity of the design and manufacture of conformal antennas for weapons systems and other airframes. FIRST RF proposes a UHF-FTS antenna, combined S- and C-Band aperture, and a novel L- ...

To address the U.S. Navy¡¦s solicitation for shipboard compliant high energy storage system, New Span Opto-Technology Inc. proposes to develop Advanced Hybrid Electrochemical Energy Storage (AESES) technology. The AESES is comprised of a foamed aluminum oxide ceramics anode and a conductive polymer cathode. The anode is made highly porous for higher capacitance. The cathode is made of an aligned ...
