Nonlinear transmission lines are interesting for two broad reasons: first, they have several direct device applications (i.e. harmonic generation, and phase
Establishing traceability for a measurement is very important so that the results of the measurement can be used in a common framework for comparisons and
Traceability of a measurement requires two parts. An unbroken chain of measurements and uncertainties for each link of the chain. The NIST Microwave Uncertainty

This talk provides an overview of recent NIST work in the Internet of Things (IoT) domain in the Information Technology Laboratory. We begin with some examples
Increase of chroma is known to be a major factor for color quality preference in lighting, and gamut area measures are often used to evaluate preference aspects
The International Energy Agencys (IEA) Energy Efficient End-use Equipment (4E) Solid-State Lighting (SSL) Annex is conducting a global interlaboratory
The correlated color temperature (CCT) is defined by the closest point on the Planckian locus from a light source on the (now obsolete) CIE 1960 (u, v) diagram
To assist development of appropriate light sources to diagnose circulatory dysfunction conditions effectively based on the color appearance of patient's skin
Firebrands generated from structures are known to be a source of rapid flame spread within communities in large outdoor fires, such as wildland-urban (WUI)
Large outdoor fires present a risk to the built environment. One example often in the international media reports are wildfires that spread into communities
This paper addresses some important theoretical issues for constrained least-squares fitting of planes and parallel planes to a set of input points. In
Employing wireless communications in gas sensing and air quality monitoring is extremely essential in many industrial scenarios where wired networks cannot
