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 ...

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 ...

THE PROPOSED RESEARCH WILL DEMONSTRATE THE APPLICATION OF A NOVEL NON-DESTRUCTIVE EVALUATION TECHNIQUE KNOWN AS SHEAROGRAPHY IN FLAW DETECTION AND CHARACTERIZATION IN STUCTURAL MATERIALS. THIS NOVEL TECHNIQUE EMPLOYS A MONO CHROMATIC LIGHT SOURCE (E.G. A LASER) AND AN OPTICAL DE DETECTION SCHEME TO REVEAL, DISCERN AND CHARATERIZE ANY ST STRESS AND STRAIN CONCENTRATION INDUCED BY DEFECTS IN MA MATE ...

THE PROPOSED PHASE I PROGRAM IS A FEASIBILITY STUDY MERCIAL SHIPS. SENSOR SYSTEMS TO BE ASSESSED WILL BE BASED ON THE INNOVATIVE METHOD OF S&S ASSOCIATES. IN THIS METHOD, TORQUESTRANSMITTED OVER A ROTATING SHAFT IN THE POWER SYSTEM ARE DETERMINED DIRECTLY FROM FIRST PRINCIPLES IN TERMS OF QUANTITIES MEASURED DURING THE SYSTEM'S NORMAL OPERATION. THE ENGINE PUTPUT TORQUE, LOAD TORQUE, ADN CHANGES I ...

A STUDY CONDUCTED BY INTERVIEWS WITH MANAGEMENT FROM PUBLIC AND PRIVATE TRANSIT OPERATORS AND METROPOLITAN PLANNING ORGANIZATIONS (MPOS) INTENDED TO DETERMINE THE FEASIBILITY AND BENEFITS OF ACCOMPLISHING FIVE OBJECTIVES IN SUBSEQUENT RESEARCH. THE OBJECTIVES ARE TO: 1. IDENTIFY THE RELATION SHIP BETWEEN EXCELLENCE IN THE PROVISION OF TRANSIT AND THE USE OF CONTRACTING WITH THE PRIVATE SECTOR; 2. ...

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 ...
