RESEARCH IS PROPOSED FOR A DEVICE TO SUPERIMPOSE STORED WEAPON IMAGES ONTO THE X-RAY SCANS OF BAGGAGE IN AIRPORTS. CRITICAL IMAGE PARAMETERS AND PROCESSING ALGORITHMS NECESSARY TO ACHIEVING A REALISTIC OVERLAY WILL BE IDENTIFIED AND DEMONSTRATED. TO MAXIMIZE THE DEVICE UTILITY, IT WILL BE PLACED BETWEEN THE VIDEO OUTPUT OF THE X-RAY MACHINE AND THE VIDEO INPUT OF THE OPERATOR'S MONITOR.SPECIAL IMA ...

A PROGRAMMABLE DEFECT SIMULATOR IS NEEDED TO TEST ULTRASONIC RAIL FLAW DETECTION SYSTEMS. CALIBRATION STANDARDS CAN BE DEVELOPED WITH VARIABLE PHYSICAL CHARACTERISTICS ACCORDING TO A PREDESCRIBED SCHEME THAT SIMULATES COMMONLY-OCCURRING FLAWS (CROSS-HEAD FATIGUE CRACKS) IN RAILWAY SYSTEM RAILS. THIS PROJECT WOULD DEVELOP A METHOD OF ALTERING THE EFFECTIVE REFLECTIVITY OF A SOLID-GAS INTERFACE THRO ...

POLYMER CONCRETE IS A RELATIVELY NEW COMPOSITE MATERIAL THATIS ALREADY FINDING INCREASING APPLICATION IN A WIDE VARIETY OF INDUSTRIAL APPLICATIONS RANGING FROM SIMPLE, UNDERGROUND UTILITY BOXES TO SOPHISTICATED MACHINE TOOL BASES AND HIGH VOLTAGE ELECTRICAL INSULATORS. IN THE HIGHWAY FIELD, POLYMER CONCRETE HAS FOUND USE AS PROTECTIVE OVERLAYS, REPAIR MATERIALS, SIGNAL/SAFETY SYSTEMS (FOR EXAMPLE, ...

THE PHASE I RESEARCH IS INTENDEDTO DEMONSTRATE THE BASIC FEASIBILITY OF CONSTRUCTING AND OPTIMIZING A NEW MAGNETO-OPTIC 'SANDWICH' DEVICE INTENDED FOR DIRECT VISUALIZATION OF FLAWSIN FERROUS MATERIALS (STEEL) IN A MARINE ENVIRONMENT. THE DEVICE IS BASED IN THE PROPERTY OF SOME MAGNETO-OPTIC GARNETFILMS TO ROTATE THE PLANES OF POLARIZATION OF AN INCIDENT, LINEARLY POLARIZED LIGHT WAVE (FARADAY MAGN ...

THE PROPOSED COMPUTER-BASED SYSTEM TO SUPERIMPOSE THE IMAGE OF THREAT WEAPONS ONTO THE X-RAY PROJECTION IMAGE OF HAND BAGGAGE IS BASED ON (1) MODELING OF X-RAY PROJECTION IMAGES OF SELECTED THREAT WEAPONS IN A VARIETY OF ROTATIONAL POSITIONS. (2) COMPUTER DETECTION AND TRACKING OF REAL-TIMEMOVING X-RAY IMAGES OF SCANNED HAND BAGGAGE. (3) COMPUTER IDENTIFICATION OF APPROPRIATE PLACEMENT OF SIMULATE ...

WE WILL DETERMINE THE FEASIBILITY OF IMPROVED METHODS FOR DETERMING AIR CONTENT IN FRESH CONCRETE. WE EXPECT THAT A STUDY OF VOLUME CHANGE WITH VARYING PRESSURE AND VACUUM WILL LEAD TO A METHOD THAT WILL INDICATE BOTH AIR CONTENT AND VOID SIZE, AND YIELD AIR CONTENTS THAT T ARE UNAFFECTED BY THE NONTHEORETICAL COMPRESSIBILITY OF SMALL VOIDS. WE WILL DETERMINE THE FEACIBILITY OF SIMPLER METHODS OF ...

THIS PROJECT IS BASED ON THE BELIEF THAT AIR TRAFFIC CONTROLTRAINING IS INDEED A TASK THAT COULD BENEFIT GREATLY FROM THE ADDITION OF SPEECH TECHNOLOGY. THIS PROPOSAL IS ALSO BASED ON THE BELIEF THAT THIS APPLICATION REQUIRES VERY CAREFUL INTEGRATION BEING AWARE OF THE SPECIFIC LIMITATIONS AND CAPABILITIES OF THE AVAILABLE TECHNOLOGIES. WE OFFER BOTH EXTENSIVE RESEARCH EXPERIENCE WITH AIR TRAFFICC ...

URBAN TRANSIT IMPROVEMENTS ENHANCE THE VALUE OF THE PROPERTY THEY SERVE. TRADITIONAL URBAN TRANSIT FINANCING TECHNIQUES NEGLECT THIS POTENTIAL SOURCE OF REVENUE. BENEFIT ASSESSMENT DISTRICTS AND IMPACT MITIGATION FEES, BASED ON CONCEPTS ORIGINALLY DEVISED FOR MINOR IMPROVEMENTS (EG. SIDEWALKS), HAVE BEEN APPLIED EXPERIMENTALLY TO URBAN TRANSIT, BUT DO NOT GENERATE THE MAJOR FUNDING URBAN TRANSIT R ...
