ALTHOUGH MANY POTENTIAL TECHNOLOGIES EXIST FOR DEPOSITING EXOTIC THIN FILM DEVICES, CONTROLLING THE MATERIAL PROPERTIES HAS BEEN A MAJOR STUBLING BLOCK TO ACHIEVING SUCCESSFUL AND REPRODUCIBLE DEVICE PROPERTIES. IN THE CASE OF PULSED LASER DEPOSITION (PLD) OF HIGH TC SUPERCONDUCTOR FILMS, THE EMISSION OF THE PLASMA CAN BE CORRELATED WITH THE QUALITY OF FILMS DEPOSITED. BUT THIS MEASUREMENT PROVIDE ...

Development of an optical water level sensor is proposed to solve some of the problems and limitations of current sounding tube/protective well acoustic sensors. By using light instead of sound, temperature gradient effects on the measurement are obviated. Furthermore, the proposed system eliminates the need for a sounding tube, protective well and associated temperature sensors, and does not requ ...

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 ...

The near-field scanning optical microscope can supply information on the shape and electrical properties of surfaces with nanometer resolution. The quantitative interpretation of images is difficult because of the difficulty of electromagnetic field solutions in the near-field limit. We propose to supply software to aid in this analysis. The finite-element programs generate two and three-dimension ...

The purpose of the VMIS is to allow manufacturers the luxury of testing and perfecting manufacturing plans long before a single machine tool is turned on and resources are committed. The VMIS will allow the user to select an available machine tool and an available inspection device, specify a proposed inspection plan and a dimensional analysis procedure, and then build and inspect hundreds (or ev ...

A growing number of fire fighters are suffering third degree burns; this has led to questions about the adequacy of thermal protective performance (TPP) measurements for protective clothing. A new heat flux sensor, whose response approximates that of skin, will be developed to provide better measurements of heat transfer in TPP tests. This sensor will be used with nonlinear parameter estimation an ...

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 ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

Measurement and real-time telemetry of tsunami wave runup height data provides an important component of the overall threat estimate at tsunami warning centers. However, there are no commercially available devices which could furnish this information. Thus, the proposed is an R&D program aimed at the development of an inexpensive, "intelligent", accurate water level data transmitter based on the ...
