UNDER IFR CONDITIONS, AIRPORT CAPACITY IS CURRENTLY LIMITED BY FAA SEPARATION STANDARDS BETWEEN AIRCRAFT. THESE STANDARDS ARE SET TO AVOID A LANDING ENCOUNTER WITH A VORTEX WAKE. IF AN ONBOARD VORTEX SENSOR AN ESCAPE SYSTEM COULD BE DEVELOPED WHICH IS BOTH RELIABLE AND INEXPENSIVE, THE A AVIATION COMMUNITY COULD BENEFIT BY DECREASED TERMINAL DELAYS WITHOUT COMPROMISING SAFETY. THE CONCEPT TO BE ST ...

SPEECH RECOGNITION IN AIR TRAFFIC CONTROL (ATC) (NOISE, MULTIPLE VOICES) AND PSYCHOLOGICAL OR PHYSICAL STRESS (PEAK TRAFFIC PERIODS, COLDS), WHILE MEETING THE NEED OF ERROR-RESISTANT OPERATION. A SUCCESSFUL DESIGN THAT "CAPTURES" THE INFORMATION ALREADY COMMUNICATED VERBALLY, HOWEVER, WOULD SAVE TIME NOW SPENT RE-ENTERING SPOKEN DATA THROUGH THE KEYBOARD AND REDUCE THE NEED FOR A CONTROLLER TO LOO ...

TWO YEARS AGO IT WAS EXPERIMENTALLY SHOWN THAT CHARGED WATERDROPLETS COULD KNOCK-DOWN SMOKE RAPIDLY. WE NOW PROPOSE TO TO DEVELOP A DEVICE WHICH USES A CHRGED FINELY POWERED SOLIDAEROSOL TO KNOCK-DOWN SMOKE. USING A SOLID INSTEAD OF A LIQUID AEROSOL HAS SIGNIFICANT ADVANTAGES. THE SOLID PART ICLES CAN BE PRE-FORMED IN A READY-TO-USE STATE. PARTICLE SIZE CAN BE RIGOROUSLY CONTROLLED AND HAVE OPTIMU ...

OVER THE LAST 5 YEARS, A NUMBER OF ULTRASONIC APPROACHES TO RESIDUAL AND APPLIED STRESS MEASUREMENTS USING EMATS HAVE BEEN REPORTED. NONE OF THESE HAS BEEN EVALUATED ON STEEL BUT THERE ARE NO FUNDAMENTAL REASONS WHY MOST CANNOT BE APPLIED TO STEEL. WHEN THE MEASUREMENT CONSTRAINTS IMPOSED BY MAKING MEASUREMENTS WITH A DEVICE ATTACHED TO A RAILCAR TESTING VEHICLE ARE CONSIDERED, TWO EMAT ULTRASONIC ...

The feasibility of the universal placement of telecommunications and power supply lines below ground, as an alternative to their typically low-cost installation on utility poles, depends upon the availability of a cost-effective convenient method for placing and replacing cables belowground. A network of underground conduits constructed of field-assembled rigid sections, including straight segmen ...

DUE TO THE IMPROVED MECHNICAL PROPERTIES AND DURABILITY OF POLYMER CONCRETE MATERIALS, THERE IS A LOT OF INTEREST IN INTHE HIGHWAY COMMUNITY FOR USE OF THESE MATERIALS FOR PAV PAVEMENT APPLICATIONS. BUT THERE IS NO INFORMATION AVAILABLEABOUT ITS APPLICATION FOR AIRPORT RUNWAY USE. PANDALAI COATINGS COMPANY PROPOSES TO TAKE UP A STUDY OF POLYMER CONCRETE MATERIALS TO EVALUATE ITS FEASIBILITY AS AN ...

TRADITIONALLY, SHIPBOARD POWER GENERATION IS ACCOMPLISHED VIA AUXILIARY ENGINES AND GENERATOR SETS. SIGNIFICANT COST ADVANTAGES CAN BE PROJECTED IF THIS ELECTRICAL DEMAND COULD BE MET BY EXTRACTING POWER FROM THE SHIP'S PRIME MOVER. TO ACCOMPLISH THIS, AND TO MAINTAIN A CONSTANT FREQUENCY ON THEGENERATOR WHILE THE SPEED OF THE PRIME MOVER VARIES OVER A WIDE RANGE, THIS CONTRACTOR PROPOSES THE USE ...

COST OF CARGO HANDLING OPERATIONS CAN BE REDUCED BY EQUIPMENT THAT USES LESS TIME AND ENERGY TO PERFORM AND RANDREQUIRES LESS MANPOWER TO OPERATE, MONITOR, AND MAINTAIN. ONE OBJECTIVE OF THIS PROPOSAL IS TO EVOLVE A PRELIMINARY DESIGN OF A REPRESENTATIVE PIECE OF MACHINERY, NAMELY A MOORING/WARPING AUTOMATIC TENSIONING WINCH USING ADVANCED ELECTRO-MECHANICAL TECHNOLOGY, ELIMINATING HYDRAULICS AND ...

WITH THE GROWING COST OF TRACK MAINTENANCE FOR HEAVY AND LIGHT RAIL TRANSPORTATION SYSTEMS, THE NEED FOR EFFECTIVE MAINTENANCE PLANNING AND FORECASTING OF MAINTENANCE REQ UIREMENTS HAS BECOME MORE READILY APPARENT. THIS IN TURN LEADS TO THE REQUIREMENT FOR AN INTEGRATED TRACK MAINTENANCEFORECASTING AND PLANNING SYSTEM THAT WILL ENABLE TRACK MAIN TENANCE SUPERVISORS TO EFFECTIVELY PLAN THEIR MAINTE ...
