Passenger safety concerns have prompted the FAA to elicit energy-sensitive neutron detectors which do not rely on the time-of-flight method and are suitable for use in explosive detection systems. Invocon, Inc. proposes to design an inspection system consisting of an energy source and a detector. Designated FERET sytem, (Field Energy Recoid Emission Technology), it would detect substances identi ...

The exchange of ship ballast water has introduced non-native organisms to ports around the world. These bioinvaders are non-indigenous species that have the potential to upset local ecological systems and economics. Various treatment methods are in limited use or experimentation: heat treatment, ultraviolet, chemical, and filtration. These are successful in eliminating a portion of the organis ...

USCG SOLICITATION 90-CG5 SUGGESTS EVALUATION OF KALMAN FILTERING A DIGITAL SIGNAL PROCESSING (DSP) TECHNIQUE, TO IMPROVE GEODETIC POSITIONING PROVIDED BY SINGLE CHAIN, AND EVENTUALLY, MULTICHAIN LORAN RECEIVERS. A DSP TECHNIQUE COMPARABLE TO KALMAN FILTERING HAS ALREADY BEEN IMPLEMENTED ON A SINGLE CHAIN LORAN RECEIVER, RESULTING IN SUBSTANTIAL GEODETIC POSITIONING IMPROVEMENTS IN NOISY, DYNAMIC E ...

N/A

A PROTOTYPE FOR AN EXPLOSIVE DETECTION SYSTEM USING PULSED FAST NEUTRON ACTIVATION (PFNA) TECHNIQUES USES AN ELECTROSTATIC TANDEM ACCELERATOR TO PRODUCE NANOSECOND WIDTH PULSES OF 6 MEV DEUTERONS. WHILE THIS APPROACH ALLOWS ONE TO PRODUCE NEUTRONS OF AN ENERGY SUITED TO THE REACTION ONE HOPES TO EXCITE IN SAMPLE ATOMS OF INTEREST, IT REQUIRES THE USE OF A FAIRLY LARGE AND EXPENSIVE ACCELERATOR SYS ...

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 ...

THE FEDERAL AVIATION ADMINISTRATION (FAA) HAS LONG BEEN INTERESTED IN THE MITIGATION OF HAZARDS TO LIFE SAFETY FROM FIRE ONBOARD COMMERCIAL AIRCRAFT. THE DEVELOPMENT OF SUPERIOR FIRE RETARDANT (FR) ADDITIVES FOR POLYMERIC MATERIALS, WHICH MIGHT BE USED IN THE INTERIORS OF AIRCRAFT, IS ONE WAY TO ADDRESS THIS PROBLEM. THIS PROPOSED PROGRAM WILL EXAMINE THE EFFICACY OF CURRENTLY AVAILABLE FIRE RETAR ...
