Not Available The technique of screen printing has been demonstrated to be of practical benefit in numerous engineering applications. Over the past two decades, these benefits have been widely recognized by the electronics industry, as evidenced by the flourishing fields of screen-printed thick-film electronics. Multilayer circuits are now manufactured by the sequential deposition of conductive an ...

The key innovation of this proposal is the use of Time Modulated Ultra-Wideband (TM-UWB) technology to develop a low cost radio system that allows both voice communication and tracking positions of fire fighters inside buildings. This radio has several characteristics which make it ideal for tracking multiple individuals without line-of-sight. During Phase I we have performed many tests, incl ...

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 ...

This is a Phase 2 proposal to develop an instrument to simultaneously measure particle size, velocity, and concentration in applications characterized by a large size range and high particle concentration. The instrument will be based on the Pulse Displacement Technique whose feasibility was demonstrated during Phase 1. Experiments performed during Phase 1 demonstrated a high accuracy in meas ...

This Phase II SBIR Project will provide optimization framework and technology for Interoperable Message Passing Interface Technology, and the underlying Message Passing Interface Standard. This effort represents a challenge and Opportunity. With the emergence of cluster computing, there are many opportunities to connect diverse parallel programming Environments based on the MPI programming mo ...

Not Available This project develops and demonstrates an innovative and economic technology that uses ultrasonic energy to destroy organisms in a ship ballast system, thereby minimizing impact from alien species introduced from shipping. Phase 1 results successfully showed that organisms were rapidly destroyed by ultrasound at various frequencies and power densities. Although the mechanism of destr ...

Not Available The goal of the proposed work is to develop a novel detector for analytical spectrometry having large active area, high-energy resolution and capable of operating at high counting rates. The proposed detector will be specifically designed for x-ray microanalysis to provide orders of magnitude advancement in the performance over conventional energy dispersive systems. During the Phase ...

Not Available The objective is to develop a horizontal ADCP (HADCP) for mapping horizontal flow structure in channels, harbors, and ports. This would be useful in areas where currents pose a threat to safe boat navigation. The Challenge for such a system is to measure flow even though bottom and surface returns could contaminate the profiles. Phase 2 will develop a long range HADCP using a frequen ...

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 ...
