NEW LIGHTING TECHNOLOGIES, INCLUDING FIBER OPTICS AND HIGH EFFICIENCY ARC SOURCES, WILL BE APPLIED IN THIS PHASE I PROJECT TO DEVELOP INNOVATIVE APPROACH LIGHTING SYSTEMS (ALS) FOR AIRPORT RUNWAYS. THE GOAL IS TO REPLACE THE LARGE NUMBER OF INDIVIDUAL INCANDESCENT SPOT LIGHTS PRESENTLY IN SUCH SYSTEMS WITH REMOTE SOURCES COUPLED TO OPTICAL WAVEGUIDES THAT WILL TRANSMIT AND PROJECT THE REQUIRED HIG ...

SCREENING BAGGAGE AND PASSENGERS FOR CONCEALED WEAPONS AND EXPLOSIVES REMAINS A SIGNIFICANT COMPONENT OF THE AVIATION SECURITY SYSTEM. RECENT TECHNOLOGICAL ADVANCES ENHANCE OUR ABILITY TO OBTAIN INFORMATION ABOUT THE SHAPE AND COMPOSITION OF CONCEALED ITEMS. HOWEVER, THE DEVELOPMENT OF DECISION SUPPORTS TO PRESENT THIS INFORMATION TO THE OPERATOR HAS LAGGED BEHIND. HOW A SYSTEM PRESENTS INFORMATIO ...

NETROLOGIC PROPOSES TO BUILD A NAVIGATION SYSTEM FOR SHIPS WHICH INTEGRATES GPS AND LORAN-C. THE GPS SYSTEM PROVIDES ASF ERROR CORRECTION TO LORAN-C SO THAT THE CORRECTED LORAN-C IS ABLE TO FURNISH NEAR GPS QUALITY GEOGRAPHICAL LOCATION INFORMATION. IN AREAS WHERE DGPS IS AVAILABLE THE DGPS SIGNAL CAN BE FURNISHED AS A REFERENE TO REALIZE CORRESPONDING GAINS IN ACCURACY FOR CORRECTED LORAN0-C. A N ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

A RESEARCH PROGRAM IS PROPOSED TO DETERMINE THE FEASIBILITY OF USING ADVANCED VACUUM INSULATIONS TO IMPROVE THE PRODUCTIVITY OF REFRIGERATED SHIPPING CONTAINERS WHILE AVOIDING THE ENVIRONMENTAL RISKS ASSOCIATED WITH CHLOROFLUOROCARBONS (CFC'S) IN FOAM INSULATION CURRENTLY BEING USED. ADVANCED VACUUM INSULATIONS, CURRENTLY UNDER RESEARCH AND DEVELOPMENT, DO NOT CONTAIN CFC'S AND HAVE VERYHIGH THERM ...

A LOW COST MEASUREMENT MODULE TAILORED TO THE APPLICATION OFSENSING RAIL LONGITUDINAL STRESS AND TEMPERATURE IS TO BE DEVELOPED AND INSTALLED IN TWO EXISTING TEST SITES. RESEARCH INTO THE BEST METHOD OF GENERATING POWER AND COMMUNICATING TO THE OUTSIDE WORLD WITHOUT HARD-WIRED CONNECTIONS IS TO BE DETERMINED. A PROTOTYPE OF THE NON-HARD-WIRED CONFIGURATION IS EXPECTED TO BE BUILT AND INSTALLED.

DOWEL BARS HAVE TRADITIONALLY BEEN USED AS AN IMPORTANT LOADTRANSFER MECHANISM ON OUR FEDERAL HIGHWAYS. A SIGNIFICANT PROBLEM OCCURRS WITH THE USE OF THESE BARS DUE TO RUST AND RESULTANT SPALLING AND CRACKING CONCRETE. COMPOSITE REINFORCING BARS (CRB) HAVE BECOME WIDELY USED FOR CRACK CONTROL IN MANY REINFORCED CONCRETE STRUCTURES EXPOSED TO AGGRESSIVE ENVIRONMENTS. A LIMITED AMOUNT OF DATA IS AVA ...

THE MODE S DATA LINK UNDER DEVELOPMENT BY THE FAA IS AN ESSENTIAL UPGRADE TO THE EXISTING AIR TRAFFIC CONTROL (ATC) SYSTEM. IN ORDER TO INSURE THE IMPROVEMENTS IN SAFETY AND EFFICIENCY OF ATC SERVICES MEDIATED BY THIS DATA LINK, IT WILL BE NECESSARY TO ASSESS ITS EFFECTS ON THE WORKLOAD AND PERFORMANCE CAPABILITIES OF AIR TRAFFIC CONTROLLERS. CONSEQUENTLY, IN PHASE I, NTI INCORPORATED WILL DEVELOP ...
