TODAY'S FIGHTING SHIPS RELY HEAVILY ON RADAR AND SONAR TO KEEP THEM OUT OF TROUBLE. ALTHOUGH SOPHISTICATED, THESE SYSTEMS STILL NEED DATA ON ENVIRONMENTAL CONDITIONS FOR PROPER OPERATION. FOR THIS REASON, IT IS IMPORTANT TO KNOW THE TEMPERATURE OF THE SEA SURFACE IN THE VICINITY OF A SHIP THAT COULD BE THE TARGET OF ENEMY FIRE. AT PRESENT, THERE IS NO GOOD WAY TO MAKE THIS MEASUREMENT. THIS PROPOS ...

NAVY VESSELS PROCESS, UTILIZE AND DISCHARGE NUMEROUS WATER STREAMS WITH VARYING QUALITY/CHEMISTRY REQUIREMENTS. BECAUSE A SOUND SHIPBOARD WATER SYSTEM IS VITAL, COMPREHENSIVE TREATMENT AND CONTROL PROCEDURES HAVE BEEN ESTABLISHED BY THE NAVY. HIGH PRIORITY IS GIVEN TO THEIR IMPLEMENTATION AND MAINTENANCE. WATER ANALYSIS IS AN IMPORTANT ASPECT OF THESE QUALITY CONTROL PROCEDURES. SEVERAL LENGTHY AN ...

THE DEVELOPMENT OF A HIGH SENSITIVITY POLARIMETRIC FIBER OPTIC MAGNETOMETER CAPABLE OF DETECTING LOW-FREQUENCY MAGNETIC FIELDS OF 10 (-12) TESLA/DIV BY HZ IS PROPOSED. THE PHASE I RESEARCH EFFORT IS PRIMARY DIRECTED TOWARD THE DEVELOPMENT OF A FIBER OPTIC MAGNETOELASTIC TRANSDUCER, OF SUFFICIENT SENSITIVITY, WHICH CONVERTS THE SIGNAL MAGNETIC FIELD TO A STRAIN AND TRANSFERS THE STRAIN TO THE CORE ...

THE DEVELOPMENT OF A COMPACT, LOW-COST INSTRUMENT FOR MONITORING THE CONCENTRATIONS OF CO, NO, AND NO(2) IN SUBMARINE ATMOSPHERES IS PROPOSED. THE INSTRUMENT WILL BE BASED ON SOLID POLYMER ELECTROLYTE SENSOR CELLS AND A NOVEL POTENTIODYNAMIC METHOD FOR DETECTING LOW CONCENTRATIONS OF GASES. THE PROPOSED DETECTION RANGES ARE: 0-400 PPM CO, 0-50 PPM NO, AND O-20 PPM NO(2). SOLID POLYMER ELECTROLYTE ...

A SEAWAY SENSOR IS NEEDED FOR 1) BETTER MATCHING SHIP DESIGN TO PERFORMANCE IN SEAKEEPING TRIALS, 2) GENERATING OPERATIONAL CONSTRAINTS, AND 3) TACTICAL APPLICATIONS WHERE FREQUENT RELIABLE ASSESSMENT OF SEA STATE HELPS CONDUCT OPERATIONS SAFETY, EFFICIENTLY AND PRODUCTIVELY. A USEFUL SEAWAY SENSOR MUST IN REAL-TIME MEASURE WAVE HEIGHT, DIRECTION AND PERIOD, THEN PRESENT OPTIMALLY USEFUL INFORMATI ...

ALLOYS BASED ON INTERMETALLIC TI(3)AL HAVE BEEN RECOGNIZED AS POTENTIAL MATERIALS TO BE DEVELOPED FOR HIGH TEMPERATURE APPLICATIONS IN ADVANCED WEAPON SYSTEMS AND AEROSPACE VEHICLES. TITANIUM ALUMINIDES POSSES LOW DENSITY, HIGH STRENGTH AND GOOD OXIDATION RESISTANCE, BUT SUFFER FROM POOR ROOM TEMPERATURE DUCTILITY. THE MAJOR CAUSES FOR LOW ROOM TEMPERATURE DUCTILITY HAVE BEEN IDENTIFIED AS (1) EXT ...

AN IMPROVED LASER DOPPLER TECHNIQUE TO MONITOR EYE ATTITUDE USING AN OPTRA DEVELOPED 2-FREQUENCY HE NE LASER IS PROPOSED. THE HETERODYNE APPROACH MAKES IT POSSIBLE TO UNAMBIGUOUSLY MEASURE EYE ATTITUDE BY INTEGRATING THE DOPPLER SHIFT OF LIGHT SCATTERED OFF THE CORNEA OR SCLERA. THE HIGH SENSITIVITY OF THIS METHOD MAKES IT POSSIBLE TO OPERATE A LOW LIGHT LEVELS--WELL BELOW THE EYE SAFETY EXPOSURE ...
