COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

FEASIBILITY STUDY FOR APPLICATION OF MICROMECHANICAL GYRO AND ACCELEROMETER TECHNOLOGY OR OTHER SOLID STATE INERTIAL SENSORS FOR INERTIALLY GUIDED CONVENTIONAL MUNITIONS. INERTIAL MEASUREMENT UNITS (IMU'S) ARE CONCEPTUALLY DEFINED FOR USE ON THE MUNITION AND ON THE WEAPON DELIVERY PLATFORM. ESTIMATES OF IMPACT ACCURACY MADE. IMU REQUIREMENTS ARE DEFINED. INNOVATIVE DUAL IMU APPROACH APPLIED TO TAN ...

ARTIFICIAL INTELLIGENCE/EXPERT SYSTEM TECHNIQUES HAVE DEMONSTRATED THE ABILITY TO ADDRESS COMPLEX REASONING TASKS REQUIRED FOR PROCESS PLANNING. FEATURE-BASED DESIGN THEORY AND PRELIMINARY EFFORTS HAVE SHOWN THE POTENTIAL OF PROVIDING A FUNDAMENTAL MODEL FOR CAPTURE AND MANIPULATION OF DESIGN KNOWLEDGE. HOWEVER, THE TWO TECHNOLOGIES HAVE NOT BEEN SUFFICIENTLY INTEGRATED TO ALLOW DESIGN FEATURES TO ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...

THE PRIMARY GOAL OF THIS PROJECT IS TO DEVELOP AND DEMONSTRATE A SIMULATION/FACTORY CONTROL CAPABILITY TO (1) SIMULATE PRODUCTS, PROCESSES, AND FACTORY CONFIGURATIONS AT MULTIPLE LEVELS OF ABSTRACTION, (2) PROVIDE FINE GRAINED ANALYSIS OF PRODUCT AND PROCESS DESIGNS, AND (3) PROVIDE A MODEL DRIVEN FACTORY CONTROL ARCHITECTURE SO THAT THE MODELS EXECUTED IN THE SIMULATION STUDIES CAN BE DIRECTLY US ...

THE PROJECT IS AIMED AT DEVELOPING A NEW TECHNOLOGY FOR PRINTED INTEGRATED FABRICATION OF ELECTROMECHANICAL SYSTEMS (INCLUDING MULTI-LAYER ELECTRIC CIRCUT BOARDS AS WELL AS OPTOELECTROMECHANICAL DEVICES SUCH AS AIRCRAFT/VEHICLE INSTRUMENT PANELS) AS A MONOLITHIC OBJECT USING A FAST LOW-COST AUTOMATABLE PROCESS THAT IS HIGHLY EFFICIENT FOR PROTOTYPING. THE PROCESS IS BASED ON SOLIDIFICATION OF LIQU ...

FUEL CELLS OPERATING IN AQUEOUS ELETROLYTES (BELOW 200¿C, DEPENDING ON THE CHOSEN ELECTROLYTE TECHNOLOGY) NORMALLY OPERATE ON HYDROGEN FUEL AND OXYGEN (OR AIR) AS THE OXIDANT. HIGH-PERFORMANCE FUEL CELL ELECTRODES REQUIRE HIGH CATALYST SURFACE AREAS, GOOD ELECTRONIC CONDUCTIVITIES AND BROAD REACTION ZONES, DEFINED BY THE CONTACT AREA BETWEEN THE CATALYST, THE GAS PHASE REACTANT AND THE ELECTROLYT ...

ALGORITHMS ARE DERIVED THAT DEFINE THE PATHS OF MAXIMUM COHERENCY FOR A SEISMIC EVENT GENERATED BY FIRING AN ARTILLERY WEAPON FROM AN ARBITRARY LOCATION. SIGNAL EXTRACTION TECHNIQUES ARE DESCRIBED TO EXTRACT THE COHERENT SIGNAL FROM AN EVENT RECORDED ON MULTIPLE RECEIVERS. SIMULATED BATTLEFIELD RECORDINGS ARE GENERATED BY TREATING THE SEISMIC SIGNATURE OF ARTILLERY WEAPONS AS IMPULSE RESPONSES FRO ...
