The capability of separating and localizing intermixed sounds in an auditory scene, also known as auditory scene analysis is the ear"s ability to handle the cocktail party effect. There are no useful models that emulate this holy grail of auditory research. Fourier-type theory and computational auditory scene analysis (CASA) techniques do not fully explain how the biological ear is able to"hear ev ...

THIS PROPOSAL DESCRIBES A NOVEL METHOD FOR TARGETING NOISY, HIGH-VALUE TARGETS SUCH AS ENEMY ARTILLERY, HELICOPTERS AND, PERHAPS, HEAVY VEHICLES AND GENERATORS. THE CONCEPT MAKES USE OF RELATIVELY INEXPENSIVE ACOUSTIC SENSORS WHICH CAN BE DEPLOYED IN ENEMY TERRITORY BY AIR DROP OR BY ARTILLERY. THE SYSTEM LOCATES TARGETS BY CORRELATING THE ACOUSTIC SIGNALS RECEIVED BY SEVERAL PAIRS OF SENSORS TO D ...

Use of"Smartphones"and cellular networks is becoming an increasing priority for military applications. By placing the source of information directly with the solider on the ground via a Smartphone, the vision of"every soldier a sensor"becomes attainable. mZeal proposes to facilitate this vision with the Adaptive Multi-Media Streaming for Android (AMMSTAR) system. AMMSTAR will capture photographic ...

Presently available electro-optic (E-0) materials are unsatisfactory for many applications due to their small E-0 coefficients and relatively large electroacoustic effect. Many other complex-oxide E-0 crystals show promise for providing substantial improvements in E-0 device performance. orders of magnitude reductions in drive voltage, power consumption, electroacoustic wave generation, and device ...

Curing of glass or carbon fiber-reinforced thermoplastic composites using high energy electron beams (HEEB) offers impressive advantages for the fabrication of structural components in commercial and military vehicles. HEEB curing greatly reduces the time to cross-link the polymer matrix, while increasing composite tensile strength. The process simultaneously cures the matrix, adhesives and paints ...

With power consumpition becoming prohibitive, SOI has become a key technological approach for production of integrated circutis with markedly reduced power requirments. SOI provides improvement (maintenance) of circuit performance and reduction of power consumption, largely independent of circuit architecture. Improved modelilng is a way of reducing the escalating cost impact of technology and pro ...

Image analysis and graphics synthesis can be achieved with learning techniques using direct image examples without physically-based 3D models. We have developed novel techniques based on computer vision and on neural network algoritms: The mapping from novel images to a vector of "pose" and "expression" parameters can be learned from a small set of example images using a function approximation tec ...

RECENT RESEARCH HAS INDICATED THE POTENTIAL BENEFITS OF AEROASSISTED ORBITAL TRANSFER MANEUVERS FOR REALIZING SIGNIFICANT FUEL SAVING OVER PURELY PROPULSIVE MANEUVERS FOR BOTH COPLANAR AND PLANAR TRANSFER USING APPROXIMATE CLOSED-LOOP GUIDANCE LAWS AND/OR NUMERICAL OPTIMIZATION ALGORITHMS. THIS RESEARCH HAS FOCUSED ON CURRENTLY ENVISAGED TRANSATMOSPHERIC VEHICLES. BASIC RESEARCH IS NEEDED TO INVES ...
