AS PAVEMENT MANAGEMENT SYSTEMS BECOME THE PRIMARY TOOL BY WHICH AGENCIES ALLOCATE THE FUNDS FOR PAVEMENT REHABILITATION, THE ACCURACY OF DISTRESS DATA. ONE OF THE LEAST EXPENSIVE BEING MANUAL DISTRESS SURVEYS. HOWEVER, MANUAL DISTRESS SURVEYS HAVE THEIR LIMITATIONS. INACCURACIES THAT ARISE IN THE ACCUMULATION AND SUMMARIZATION OF THE DISTRESS DATA CAN LIMIT OR IMPAIR ITS USE SIGNIFICANTLY. ONE WAY ...

FIBER MATERIALS, INC. (FMI) PROPOSES SENSORS WHICH CAN BE EMBEDDED IN PAVEMENT TO MEASURE STRESS AND STRAIN FROM TRUCKS PASSING OVER AT SPEEDS UP TO 60 MPH. THESE SIMPLE, DURABLE SENSORS WILL BE MADE FROM PIEZOELECTRIC COMPOSITES WHICH ACT AS PASSIVE SENSORS AND DEVELOP A CHARGE PROPORTIONAL TO THE APPLIED PRESSURE. THE CHARGE IS CONVERTED TO A VOLTAGE WHICH IS RECORDED ON NEARBY EQUIPMENT. THE PH ...

THE UNITED STATES COAST GUARD (USCG) HAS LONG BEEN INTERESTED IN THE MITIGATION OF HAZARDS TO LIFE SAFTEY FROM FIRE ONBOARD SHIPS. THE DEVELOPMENT OF SUPERIOR FIRE RESISTANT COATINGS FOR GLASS-REINFORCED POLYMERIC (GRP) COMPOSITES, WHICH MAY BE USED AS BULKHEADS, DECKS AND INTERIORWALLS, IS ONE WAY TO ADDRESS THIS PROBLEM. THE COAST GUARD, OTHER GOVERNMENT AGENCIES (E.G., THE U.S. NAVY) AND NUMERO ...

WE PROPOSE TO DEVELOP DETECTORS FOR EXPLOSIVES IDENTIFICATION BASED ON THREE NEW FAST HEAVY CERIUM-DROPPED PEROVSKITE SCINTILLATOR CRYSTALS: YAP, GAO, AND GSO. WE HAVE MADE DETECTORS FROM SMALL (~200 MM(2)) THIN (~40 MM) CRYSTALS OF THESE MATERIALS WHICH HAVE MEASURED EFFICIENCIES, RESOLUTIONS, LIGHT, AND MECHANICAL PROPERTIES COMPARABLE TO OR BETTER THAN THOSE OF NAI AND BGO, THE CURRENT EXPLOSIV ...

A 3-DIMENSIONAL ATTITUDE SENSOR WHICH USES GPS CARRIER PHASEINTERFEROMETRY IS PROPOSED FOR ANALYSIS AND CONCEPT TESTING IN PHASE I, AND PROTOTYPING IN PHASE II. THE RESULTING SENSOR WILL BE ACCURATE AT ANY LATITUDE. ADROIT SYSTEMS PROPOSES TO ENHANCE ITS SUCCESSFUL 2-DIMENSIONAL, STATIC GPSATTITUDE DETERMINING SYSTEM (ADS) SO THAT IT WILL OPERATE UNDER DYNAMIC CONDITIONS WHILE MEASURING 3-DIMENSIO ...

AN INNOVATIVE OBSTACLE DETECTION SYSTEM BASED ON A RAIL-GUIDED PROPELLER-DRIVEN POD CONTAINING A MICROWAVE RADAR SENSOR IS PROPOSED. THE SENSOR POD WILL TRAVEL A FEW MILES AHEAD OF THE HIGH SPEED TRAIN OR MAGLEV VEHICLE, DETECT POTENTIAL OBSTACLES, AND ENACT AN APPROPRIATE WARNING OR AVOIDANCE PROCEDURE. THE PROPOSED OBSTACLE DETECTION SYSTEM HAS MANY HIGHLY DESIRABLE FEATURES INCLUDING: A VERY LO ...

THE ULTIMATE OBJECTIVE OF THIS RESEARCH EFFORT IS THE DEVELOPMENT OF A SHIP MANEUVERING SIMULATION SOFTWARE PACKAGE FOR SHIPBOARD USE IN MANEUVERING ASSESSMENT, PASSAGE PLANNING AND TRAINING. THE SOFTWARE MUST OPERATE IN A STAND ALONE MODE AND/OR INTEGRATED WITH THE SHIP'S NAVIGATION AND CONTROL SYSTEM. THE PHASE 1 EFFORT INCLUDES THE INITIAL DETERMINATION OF THE REQUIREMENTS FOR THIS SOFTWARE PAC ...

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 ...
