Manufacturing industry is facing an enormous challenge today in trying to integrate a wide range of systems. The systems span the functional areas of...
Firefighters and other emergency responders often work in adverse environments. The operating environments can be very noisy. Personal Alert Safety Systems...
This report documents the procedures used to develop certified maximum force and absorbed energy values for SRM 2112 and SRM 2113. The report serves to provide...
Experimental data have been gathered by applying 3D imaging systems, such as LIDAR/LADAR instruments, to spherical objects. This report provides a compilation...
Runs of the NSTAB equilibrium and stability code show there are many 3D solutions of the advanced tokamak problem subject to axially symmetric boundary...
Project 25 (P25) is a standards development process for the design, manufacture and evaluation of interoperable digital two-way wireless communications products...
Of all the aspects of destruction kinetics measurement, the one taken most for granted is temperature measurement. The ubiquity of digital thermometers and...
Many people telework (also known as telecommuting), which is the ability for an organization s employees and contractors to perform work from locations other...
Hurricanes wreak havoc on the lives and infrastructure of coastal communities. Storm surge, a local rise in sea level elevations, is perhaps the most...
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or mixtures of refrigerants. The model can simulate a basic...
The NIST SAMATE project conducted the first Static Analysis Tool Exposition (SATE) in 2008 to advance research in static analysis tools that find security...
To evaluate the performance of fingerprint-image matching algorithms on large datasets, a receiver operating characteristic (ROC) curve is applied. From the...
