DIVER SCIENTIST COMMONLY RELY ON A VARIETY OF INSTRUMENTS TO ACCOMPLISH THEIR MISSION. USING MULTIPLE SPECIALIZED INSTRUMENTS HOWEVER NOT ONLY IS COSTLY, BUT ALSO LIMITS A DIVERS MOBILITY. STILL, MANY CAPABILITIES TAKEN FOR GRANTED BY "TOP-SIDE" FIELD RESEARCHERS, SUCH AS PRECISE NAVIGATION AND COMPUTERIZED RECORD TAKING, REMAIN UNSATISFIED OR ARE NOT ADEQUATELY ADDRESSED BY CONVENTIONAL MEANS. TH ...

SILICON P-N JUNCTION PHOTODIODES (AXUV DIODES) WITH STABLE, THEORETICALLY PREDICTABLE QUANTUM EFFICIENCIES IN THE SOFT X-RAY (1 TO 100 NM) WERE DEVELOPED BY US RECENTLY LEADING TO THEIR USE FOR THE ESTABLISHMENT OF AN INDEPENDENT RESPONSIVITY SCALE FOR THE SOFT X-RAY REGION. THE LARGEST ACTIVE AREA DIODE DEVELOPED SO FAR IS 3 CM(2) LIMITING THE SOLID ANGLES DURING SURFACE ANALYSIS STUDIES. FABRICA ...

EXPERIMENTS AT THE MASSACHUSETTS INSTITUTE OF TECHNOLOGY, THE JOHNS HOPKINS UNIVERSITY, AND QUANTUM MAGNETICS HAVE SHOW THAT CORROSION REACTIONS CREATE MEASURABLE MAGNETIC FIELDS. IN CONTRAST TO OTHER TECHNIQUES, MAGNETIC DETECTION OFFERS THE POSSIBILITY OF DIRECTLY DETECTING CORROSION PROCESSES NONINVASIVELY FROM OUTSIDE THE CORRODING VESSEL. IN PHASE 1, IN COLLABORATION WITH THE MARINE CORROSION ...

DIFFERENCE FREQUENCY MIXING USING DIODE LASERS AS PUMP AND SIGNAL SOURCES PROMISES TO PROVIDE A CHEAP, COMPACT ROOM-TEMPERATURE SOURCE OF MID-IR RADIATION FOR INSTRUMENTS BASED ON IR ABSORPTION. HOWEVER, HIGH POWER TUNABLE SPECTROSCOPIC-QUALITY DIODE LASERS REQUIRED FOR DFM ARE CURRENTLY LACKING. SDL PROPOSES A HIGH POWER TUNABLE LASER THAT PROVIDES OVER ONE WATT OF CW DIFFRACTION-LIMITED SINGLE-S ...

WE PROPOSE TO DEVELOP AN ADVANCED OPTICAL-FLOW MOTION ESTIMATION AND SEGMENTATION ALGORITHM FOR USE WITH MOBILE ROBOTS. BASED UPON OUR EARLIER WORK ON OPTICAL-FLOW IMAGE ANALYSIS, AN ADVANCED OPTICAL-FLOW SEGMENTATION ALGORITHM, USING DISCONTINUITY INFORMATION IN BOTH VELOCITY AND INTENSITY DOMAINS, PERMITS THE SEGMENTATION OF VIDEO SEQUENCES ALONG NATURALLY OCCURING MOTION BOUNDARIES. ESTIMATING ...

SINCE THE DISCOVERY OF THE "OZONE HOLE" THE MONITORING OF LONG TERM TRENDS AND GEOGRAPHICAL VARIABILITY OF UV IRRADIANCE AND HOW IT IMPACTS OUR ENVIRONMENT HAS BECOME INCREASINGLY IMPORTANT. THERE IS AN IMMEDIATE NEED TO DEPLOY NETWORKS OF SUITABLE INSTRUMENTATION YET THERE APPEARS TO BE NO SIGNIFICANT LEVEL OF AGREEMENT THAT SUITABLE AND COST-EFFECTIVE ALTERNATIVES EVEN EXIST. THIS PROPOSED EFFOR ...

SILICON PHOTODIODES WITH STABLE, THEORETICALLY PREDICTABLE QUANTUM EFFICIENCY IN THE XUV SPECTRAL RANGE HAVE BEEN RECENTLY DEVELOPED BY RAJ KORDE AND SCIENTISTS AT NIST. SCIENTISTS AT BESSY AND PTB IN GERMANY HAVE INDEPENDENTLY CONFIRMED THAT THE CALCULATED QUANTUM EFFICIENCY OF THESE XUV SILICON DIODES CAN BE USED FOR THE ESTABLISHMENT OF AN INDEPENDENT RESPONSIVITY SCALE IN THE XUV SPECTRAL RANG ...

DATA INTENSIVE APPLICATIONS PLACE A BURDEN ON EXISTING DATABASE SYSTEMS. ESPECIALLY ACUTE ARE THE REQUIREMENTS PLACED BY APPLICATIONS THAT REQUIRE DATABASE SEMANTICS BEYOND THE SCOPE OF EXISTING ENVIRONMENTS. WORK IN OBJECT-ORIENTED DATABASE TECHNIQUES PROMISES TO ALLEVIATE SOME OF THESE PROBLEMS. RECENT DEVELOPMENTS IN EXTENSIBLE DATABASE ENVIRONMENTS WILL SUPPORT THE INTEGRATION OF OBJECTAPPROAC ...
