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 ...

50134-98-I Control of Microbiologically Influenced Corrosion Using Anticolonization Agents--Bioindustrial Technologies, Inc., 40105 Industrial Park Circle, Georgetown, TX 78626-4702; (512) 869-0580 Dr. Daniel H. Pope, Principal Investigator Dr. Daniel H. Pope, Business Official DOE Grant No. DE-FG03-98ER82540 Amount: $73,981 Microbiologically influenced corrosion (MIC) is a very serious type o ...

A GENERAL-PURPOSE, SOLUTION-ADAPTIVE, FINITE-ELEMENTS CODE THAT TREATS BROAD CLASSES OF INCOMPRESSIBLE FLOWS HAS BEEN DEVELOPED. THE CODE EMPLOYS H-ADAPTIVE AND P-ENRICHMENT ALGORITHMS THAT REFINE THE STRUCTURE OF THE MESH TO OPTIMIZE COMPUTATIONS. THE FULL POTENTIAL FOR USE OF SUCH SMART ALGORITHMS IN COMPUTATIONAL FLUID DYNAMICS APPEARS TO LIE IN PARALLEL COMPUTATIONS PRIMARILY BECAUSE OF THE EX ...

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 ...

THE HIGH PRESSURE LIMITS OF A NEW PROPRIETARY TECHNIQUE FOR SURFACE ELEMENTAL AND ISOTOPIC ANALYSIS ARE BEING EXPLORED. THE TECHNIQUE SHOULD BE USEFUL IN THE MILLITORR PRESSURE REGIME, THUS ALLOWING MEASUREMENT OF THIN FILM STOICHIOMETRY DURING GROWTH AND PROCESSING. THE PRESENT RESEARCH IS FOCUSING ON ANALYSIS OF YTTRIUM-BARIUM-COPPER-OXYGEN (YBCO) SUPERCONDUCTOR FILMS SUBJECTED TO HIGH PRESSURES ...

A METHOD TO MEASURE NONDESTRUCTIVELY THE BIAXIAL RESIDUAL STRESSES IN FERRITIC PIPING WELDS WITHIN FOSSIL-FIRED AND NUCLEAR-POWERED ELECTRICITY GENERATING PLANTS IS PLANNED. THE METHOD USES THE MAGNETICALLY INDUCED VELOCITY CHANGES OF ULTRASONIC WAVES TO DETERMINE THE STRESSES. IT IS BEING SHOWN THAT THE METHOD CAN DETERMINE THE ABSOLUTE VALUES, SIGN, AND ORIENTATION OF THE AXIAL AND CIRCUMFERENTI ...
