We provide an overview of the current state of high-frequency and microwave metrology programs at NIST, as well as a discussion of recent changes, emerging
In this article we propose an adaptive algorithm that determines the duration and frequency of channel scanning in order to facilitate the discovery of
The telecommunications and electric power industries both operate systems that depend upon precise time synchronization or frequency control. These systems

Radio frequency (RF) and analog/mixed-signal (AMS) integrated circuits (ICs) are key enabling components for mobile and wireless communications and their
We demonstrate a new method for measuring transverse stress with 11.8 υm spatial resolution in a fiber Bragg grating sensor, without the use of polarization
Display performance under ambient conditions is as important for display characterization as are darkroom measurements. We review ambient-contrast measurements
The robust retrieval track explores methods for improving the consistency of retrieval technology by focusing on poorly performing topics. The retrieval task in
The goal of the enterprise track it to conduct experiments with enterprise data-- intranet pages, email archives, document repositories -- that reflect the
We describe the wafer-level fabrication of cesium vapor cells by evaporation and photolysis of cesium azide for chip-scale atomic devices. The advantage is that
Low frequency (LF) noise is studied in nMOSFET with various HfO2 dielectric or interfacial layer (IL) thickness and TiN as gate electrode material. LF noise
The Performance Metrics for Intelligent Systems (PerMIS 2006) workshop was held during August 21-23, 2006 at the National Institute of Standards and Technology
Rising automation means fewer humans, maintaining more equipment, which is exchanging more information. This information torrent is expected to increase even

The National Institute of Standards and Technology (NIST) has recently studied a new 3D range camera for use on mobile robots. These robots have potential
A piece of automation equipment such as a robotic crane for steel erection has no intrinsic knowledge of the process it automates. Thus, geometric and spatial

Imaging and spectroscopy at terahertz frequencies (defined roughly as 300 GHz-3 THz) have great potential for both healthcare and homeland security applications
We use a rotating dihedral to determine the cross-polarization ratios of radar cross section measurement systems. Even a small amplitude drift can severely
First responders and incident management personnel need better training resources to prepare for future disasters. Live training exercises while valuable are
