New Generation Access Control (NGAC)—because of its “neutrality by design”—represents the most effective and scalable approach for deploying “smart” access control and consent solutions in large dynamic scenarios. NGAC however presents with its own problems: (1) it has miniscule recognition and uptake in the workplace, (2) it is unusable by non-technical policy officers and (3) its doc ...

Infrasound and seismic measurements are used by DTRA and the DoD for nuclear test monitoring, terrorist blast forensics, battle damage assessment, and environmental monitoring. However, these long wavelength physical signals are typically recorded through single-point sensors or sparse low density arrays. As a result, the critical signals of interest are often corrupted or masked by noise or inter ...

This proposal describes the development of a generalized toolkit that enables improved and automated mapping of partitioned subdomains onto available distributed compute nodes for applications operating within pure-MPI or hybrid-MPI parallel runtime environments. This toolkit may be invoked either as an independent pre-processing step or as a dynamic library, improving an applications real-time do ...

The Temperature Programmed Sensing (TPS) system developed at NIST presents many opportunities and unique challenges. The data output from the system can be quite complex and there are many opportunities to optimize the system for specific sensing scenarios. We propose a program aimed at characterizing the system so that potential problems (such as system drift) can be solved early so that the full ...

NIST has developed an ultraviolet weathering device ¿ SPHERE (Simulated Photodegradation via High Energy Radiant Emission) based on integrating sphere technology that is used to accelerate the degradation of polymeric materials. SphereOptics is a manufacturer of integrating spheres and has experience in developing high radiance output uniform sources based on sphere technology. Given its manufa ...
