AER PROPOSES TO DEVELOP A NEW CONCEPT IN PROVIDING WEATHER \FORECASTING FOR INDUSTRY, MADE POSSIBLE BY THE DECREASING COSTS OF POWERFUL COMPUTERS. IMPROVED SHORT-RANGE FORECASTS WOULD BE OBTAINED BY RUNNING A MODEL ON THE USER'S COMPUTER. THE MODEL WOULD ACCESS THE FORECASTS OF THE NATIONAL METEROLOGICAL CENTER AND MODIFY THEM THROUGH A DETAILED SIMULATION OF THE PHYSICS OF ATMOSPHERIC PROCESSES,T ...

WE PROPOSE TO APPLY ARTIFICIAL NEURAL NETWORKS TO THE DERIVATION OF CLOUD MOTION VECTORS FROM SATELLITE IMAGERY. IN PHASE I, WE WILL CONCENTRATE ON USING A NEURAL NETWORK IN THE FIRST STEP IN THE DERIVATIO OF CLOUD MOTION VECTORS, THE HEIGHT ASSIGNMENT AND TARGET SELECTION. THE NEURAL NETWORK COMBINES, AT EACH IMAGE PIXEL, BRIGHTNESS IN DIFFERENT CHANNELS TO DETERMINE CLOUD TYPE AND LEVEL (I.E., L ...

This project will design and deliver a high accuracy monitor for the photo-chemically coupled pollutants nitric oxide, nitrogen dioxide and ozone using infrared absorption spectroscopy with quantum cascade (QC) lasers. The target molecules are monitored at air quality stations worldwide using instruments which require frequent calibration and are subject to significant chemical interferences (in t ...

Solid-state light sources promise many advantages over traditional technologies. Among these advantages is the ability to construct a source whose relative spectral distribution can be tuned to better match a desired spectrum. We propose addressing this technical and market opportunity through the development of a novel single-chip semiconductor device which delivers high optical output power (>20 ...

The use of thermal neutrons has been widespread over the past several decades in many investigations such as non-destructive testing (NDT), neutron radiography and macromolecular crystallography. For some applications such as crystallographic diffraction studies, neutrons are scattered over 4o in space and an ideal detector would be able to image the scattered radiation on a spherical surface. Cur ...

WE WILL DEVELOP WAVELET-BASED DOMAIN DECOMPOSITION PROCEDURES FOR THE SOLUTION OF THE INITIAL VALUE PROBLEM FOR THE SCHROEDINGER EQUATION ON MULTIDIMENSIONAL SPATIAL DOMAINS. ACCURATE AND PRACTICAL NUMERICAL CALCULATIONS WOULD BE OF GREAT USE IN THE IMPLEMENTATION AND EXTENSION OF THE BORN-OPPENHEIMER PROCEDURE. BEING BOTH COMPACTLY SUPPORTED AND ORTHOGONAL, WAVELETS COMBINE THE ADVANTAGES OF FINI ...

In this NIST SBIR program Boston MicroSystems develops MEMS-based fluid viscosity-density sensors which can be installed in refrigerant system compressors to monitor, in real time, refrigerant system health. Such sensors will provide early detection of water contamination, lubricant degradation and other problems which can lead to catastrophic refrigerant system failure if left uncorrected. Such s ...
