The development of a greatly enhanced receiver for the WWVB signal is targeted, as well as possible modifications in the transmitted signal, which would both offer significant improvements in its effective coverage. This is to be achieved while allowing the replacement of the bulky, expensive, ferrite-based antenna, commonly used in the receiver, with a novel lower-cost antenna. Furthermore, the p ...

Perform a feasibility study on developing a face recognition application in a cloud computing environment utilizing MBARK as the middleware. The application will have a client piece that will run on a mobile device and a server piece that will run on a higher-performance computing cluster. The specific objectives of the feasibility can be enumerated as follows: 1. Split/distribute the MBARK middle ...

Improving the quality and intensity of the x-ray beam is an important design goal for every synchrotron installation. Although small, the effects of vacuum windows on x-ray absorption and phase contrast cannot be neglected. Synchrotron x-rays have wavelengths on the order of one Angstrom (1 x 10-10m), the same order of magnitude as inter-atomic distances. These x-rays are used to study many differ ...

NIST desires to develop a standard of pressure in the range of 0.3Mpa to 10 Mpa based on measurements of the dielectric constants of gaseous helium and argon. This requires capacitance measurements having a better linearity than can be made with any currently available product. It is proposed that the design of what is currently the most precise commercial capacitance bridge be modified to improve ...

THE FRANTIC COMPUTER CODE IS THE MOST ADVANCED MODEL FOR ADDRESSING TIME-DEPENDENT RISK EFFECTS ASSOCIATED WITH TECHNICAL SPECIFICATIONS. IT IS USED BY THE INDUSTRY FOR THE EVALUATION OF UPGRADES AND/OR IMPROVEMENTS IN EXISTING TECHNICAL SPECIFICATIONS AND BY THE NRC STAFF IN RESPONDING TO THE LICENSEE SUBMITTALS. THE EXISTING METHODOLOGY HAS TWO MAJOR DEFICIENCIES: IT DOES NOT PROVIDE THE BOUNDIN ...

In the proposed Phase I SBIR program, Aymont Technology and CoolCAD Electronics will design and demonstrate prototype silicon carbide (SiC) avalanche photodiodes (APD) specifically designed for high-efficiency, single-photon counting of 121.6 nm Lyman-alpha photons. This detector will be provided to relevant personnel at NIST for calibration and testing. Both discrete APDs and arrays will be used ...

This SBIR deals with developing a commercial AC Resistance-Ratio Bridge based on research work done by R. D. Cutkosky at NIST during the 1980's. His initial work will be extended by this Phase 1 project to allow for a new state-of-the-art product design and development. The product, the Model 8686 Precision Resistance-Ratio Bridge, will have an operating current range from 0.1mA to 10mA user selec ...

The result of this project will be a fully functional prototype of the Model 8686H Precision Resistance-Ratio AC Bridge. The unit is capable of measuring resistances from 0 to 400 ohms with better than 0.1 uohm resolution and an accuracy of better than +/-0.05ppm. The unit will have advanced features such as a built-in web-browser, USB interface and built-in complex functions. Examples of such com ...
