More that 52% of the U.S. highway congestion in urban areas is a direct result of highway incidents. Federal and State transportation authorities are searching for quick, low-cost and efficient highway incident detection and warning systems. Several solutions have been proposed but none could meet the requirements of transportation authorities. Central Signal, funded by federal agencies, has done ...

The TEXAS Model for Intersection Traffic is a high-quality single-intersection microscopic traffic simulation model developed at The University of Texas at Austin. It analyzes in sub microscopic detail the behavior of driver-vehicle units as they go through an intersection and intermix with other traffic flows. It has detailed intersection geometry, path following, microscopic car following, lan ...

ANTROPIX CORPORATION PROPOSES TO OBTAIN TIME - RESOLVE OPTICAL PROPERTIES MEASUREMENTS (PLASMA OPACITY IN THE 8 - 12 MICRON SPECTRAL REGION, AS WELL AS STARK BROADENING AND RELATIVE INTENSITY PARAMETERS) ON BROADBAND PLASMA BARRIERS (BPBS) GENERATED BY LASER ACTIVATION OF ALKALI METAL (E.G., NA AND CS) VAPORS. SIMILAR MEASUREMENTS WILL BE COMPLETED ON KNOWN PHASE TRANSITION MATERIALS (PTMS) SUCH A ...

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 ...

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 ...

Knexient proposes POINT2, a processing system for OSI on the Web. Specifically, POINT2’s text processing engine finds primary types—main events or entities discussed in online news. When the primary type is an event, it is related to its location and time of occurrence. The location of the primary event is converted into lat/lon coordinates and presented on KnexientGlobe, a custom geospatia ...

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 ...

Reliable sample preparation from a variety of complex matrices remains one of the most challenging problems facing biological detection in the field. This is especially true for isolation of nucleic acids from an environmental or clinical sample. A clean nucleic acid sample, free from contaminating materials such as cell debris, dirt and inhibitory chemicals, is required to ensure the robust perfo ...

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 ...
