In the defense industry today, high level SysML system models are used by engineers beginning early in the design process to functionally decompose the system being designed and to flow down requirements to sub-systems and components. Despite their usefulness, these system models are by and large descriptive models and not analytical (executable) models. In contrast, domain level engineers (struct ...

IN THIS PROPOSAL WE DISCUSS THE DEVELOPMENT OF A BLUE (POTENTIALLY GREEN AND OTHER WAVELENGTHS ALSO) SOLID STATE LASER BASED ON PN-JUNCTION HETEROSTRUCTURES IN THE AIXGA1-XN MATERIAL SYSTEM. THESE AIXGA1-XN BASED LASERS WILL BE IDEAL FOR USES IN OPTICAL RECORDING, COMMUNICATION AND LARGE SCREEN DISPLAY SYSTEMS. ESSENTIALLY ALL APPLICATIONS CURRENTLY BEING ADDRESSED BY ARGON-ION LASERS WILL BE IMPA ...

Social network analysis is a powerful method for making sense of an increasingly interconnected world. Developing social network analysis tools requires datasets with which to test them, but sharing datasets is problematic because of privacy issues. Initial attempts to anonymize network datasets proved ineffective due to de-anonymization attacks that leveraged publically available information to i ...

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 ...

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 ...

A PROTOTYPE OF ESM/ELINT RECEIVER SYSTEM UTILIZING ACOUSTIC CHARGE TRANSPORT (ACT) TECHNOLOGY IN AN ADAPTIVE CHANNELIZER IS PROPOSED. THE TYPES OF ACT TECHNOLOGY TO BE EXPLOITED IN THIS DEVELOPMENT ARE TUNABLE FILTERS WITH PROGRAMMABLE BANDWIDTHS AND ADJUSTABLE DELAY LINES FOR DELAY LINE DISCRIMINATORS. A VERY LONG DELAY USING ACT TECHNOLOGY WILL ALSO BE INVESTIGATED. THIS ADAPTIVE RECEIVER BUILDS ...
