International System of Units (SI)

Ongoing
Members of the Fundamental Constants Data Center (FCDC) participate in meetings of the Consultative Committee for Units (CCU) which advises the International Committee for Weights and Measures on matters concerning the SI. The latest meeting of the CCU, held at the BIPM in June of 2013 was attended

Internet Infrastructure Protection

Ongoing
In the FY 2016 ITL staff made significant contributions in the design, standardization, test and measurement of technologies to improve the security and robustness of the Internet’s global routing protocol BGP. NIST staff are key contributors to Internet Engineering Task Force (IETF) standards to
Dual SIM solution

Inter-Network Mobility Management

Ongoing
The Middle Class Tax Relief and Job Creation Act of 2012 (H.R. 3630) appropriated $7 billion for the establishment of a nationwide interoperable public safety broadband network under FirstNet, an independent authority in the National Telecommunications and Information Administration (NTIA). FirstNet

Ion Mobility Spectrometry

Ongoing
IMS employs a drift tube with an applied electric field to separate ionized molecules based on their mobility. The technique is robust and capable of differentiating a wide range of drug and explosive molecules. Recent work has sought to investigate the utility of IMS for screening of illicit

Ion Traps

Ongoing
Trapped ions are sensitive to electric-field noise from trap-electrode surfaces. This noise has been an obstacle to progress in trapped-ion quantum information processing (QIP) experiments for more than a decade. It causes motional heating of the ions, and thus quantum-state decoherence. This

Iris Challenge Evaluation (ICE)

Completed
ICE 2006 Workshop ICE 2006 consisted of a large-scale, open, independent technology evaluation of iris recognition technology. To guarantee an accurate assessment, the ICE measured performance with sequestered data (data not previously seen by the researchers or developers

Iris Exchange (IREX) 10: Ongoing Evaluation of Iris Recognition

Ongoing
IREX 10 is a continuing evaluation of automated iris recognition technology. Administered at the Image Group's Biometrics Research Laboratory (BRL), developers submit their matching software for analysis over sequestered test data. As an ongoing evaluation, developers may submit their software at

Iris Exchange (IREX) Overview

Ongoing
The data used in IREX comes from publicly available datasets and from operational data provided by various government and commercial entities. The publicly available data sets may be procured from the original sources; in general, NIST does not have license to redistribute any of the public datasets

Iris Experts Group - II Homepage

Ongoing
Documents for Public Comment Some of our IEG activities generate documents that may benefit from public comment. There are three general categories: Documents that are sent to OSAC for further work. Documents that are provided to another entity (e.g. FBI NGI) for dissemination. Documents that will

Iris Projects

Ongoing
IRIS Experts Group II Starting in June 2016, NIST is convening the Iris Experts Group as a series of colloquia addressing topics of interest to operational deployment of biometrics in the United States government and more broadly. Iris Exchange (IREX) The Iris Exchange (IREX) was initiated at NIST

Isotope Metrology

Ongoing
The application of isotope measurements drives advances in an enormous number of fields and stakeholder engagements, including federal and state government agencies, academia, and private industry including the medical industry. The objective of the NIST Isotope Metrology Program is to address the

Isotopes as Environmental Tracers in Biological Specimens

Ongoing
Multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS) provides sensitive and precise measurements of stable isotope ratios and can be coupled to a variety sample introduction systems such as laser ablation and gas or liquid chromatography. The versatility and performance of MC-ICP

ITL Forensic Science Program

Ongoing
The principal goals of the Program are to develop standards, measurement methods, tests, validation studies, and technology to: Better understand and improve the accuracy and reliability of forensic science. Provide scientifically validated bases for forensic methods and standards. Establish

ITL Quantum Information Program

Ongoing
The principal goals of the ITL Quantum Information Program are: To understand the potential (both opportunities and risks) for quantum information to revolutionize information science. To develop theory, methods, architectures and algorithms to enable engineering and testing of quantum computing
NIST JARVIS

JARVIS-ALIGNN, JARVIS-ALIGNN-FF

Ongoing
ALIGNN uses a line graph neural networks to include bond distances and angular information graph to incorporate finer details of atomic structure, leading to high accuracy models. While the nodes of an atomistic graph correspond to atoms and its edges correspond to bonds, the nodes of an atomistic

JARVIS-DFT

Ongoing
JARVIS-DFT hosts materials property data for ~40000 bulk and ~1000 low-dimensional crystalline materials and the database is continuously expanding. Some of the properties in the database are: formation energies, bandgaps, elastic, piezoelectric, dielectric constants, and magnetic moments

JARVIS-FF

Ongoing
Many classical force-fields are developed for a particular set of properties (such as energies) and they may not have been tested for properties or configurations outside the training (such as elastic constants, defect formation energies or energies for metastable phases). JARVIS-FF provides an
JARVIS-ML overview

JARVIS-ML

Ongoing
JARVIS-ML introduced Classical Force-field Inspired Descriptors (CFID) as a universal framework to represent a material’s chemistry-structure-charge related data. With the help of CFID and JARVIS-DFT data, several high-accuracy classifications and regression ML models were developed, with
NIST Shielded Room

Johnson Noise Thermometry

Completed
The NIST Gaithersburg JNT project produces data useful for verification of the International Temperature Scale of 1990 (ITS-90) over a temperature range from 500 K to 930 K. This range overlaps those covered by other thermodynamic methods, most notably the upper-most range of Acoustic Thermometry

Key Comparisons and International Interlaboratory Studies Project
