THE U.S. WEATHER SERVICE PRESENTLY USES A "TIPPING BUCKET" RAIN GAUGE FOR MEASURING RAIN ACCUMULATION. THIS DEVICE IS SENSITIVE TO WIND AND MOTION (AS ON BUOYS), CANNOT MEASURE RAIN RATE, AND REQUIRES FREQUENT MAINTENANCE, BECAUSE OF MOVING PARTS. AN ALTERNATIVE DEVICE IS BEING PROPOSED, WHICH INCORPORATES A RIGID, RESONANT TUBE, CLOSED AT THE TOP BY AN ELECTRO-ACOUSTIC TRANSDUCER, AND AT THE BOTT ...

FIBER OPTIC SENSORS HAVE VERY ATTRACTIVE FEATURES FOR INDUSTRIAL APPLICATIONS. BECAUSE THEY USE NONCONDUCTING SILICA INSTEAD OF WIRES, THEY CAN OPERATE IN HIGH ELECTROMAGNETIC FIELD ENVIRONMENTS AND EXPLOSION HAZARD AREAS. THE EXPECTATIONS OF THE 1980S WERE THAT FIBER OPTIC SENSOR USAGE WOULD BE OVER $100M PER YEAR IN 1993; ACTUAL SALES WERE UNDER $20M. THE ORDER-OF-MAGNITUDE ERROR WAS IN PART DUE ...

MSI PROPOSES TO INCORPORATE BACKGROUND SUBSTITUTION OF "FAULTY MODELS" IN CAD DESIGN SIMULATION OF ELECTRONIC CIRCUITS TO PERFORM A "DESIGN OF EXPRIMENTS" DETERMINATION OF SENSITIVITY TO PARAMETRIC VARIATION IN COMPONENTS. THE INFORMATION LEARNED WILL BE USED TO SELECT COMPONENTS THAT WILL HAVE A LONGER LIFE, AND GREATER DURABILITY. THIS FORM OF ANALYSIS COMBINED WITH WORST CASE SENSITIVITY ANALYS ...

SURPLUS OFFSHORE OIL PLATFORMS AND SIMILAR STRUCTURES HAVE POTENTIAL AS BASES FOR THE SUPPORT OF OFFSHORE AQUACULTURE OPERATIONS. ONE CONCEPT DEVELOPED AT NET SYSTEMS ENVISIONS A PLATFORM SURROUNDED BY, AND HELPING TO SUPPORT, A RINGSHAPED ARRANGEMENT OF FLOATING FISH PENS. HOWEVER, BEFORE SUCH STRUCTURES CAN BE INCORPORATED INTO AQUACULTURE SYSTEMS, WE NEED TO BE ABLE TO PREDICT THEIR RESPONSE TO ...
