Biometric Quality

Ongoing
Quality analysis is a technical challenge because it is most helpful when the measures reflect the performance sensitivities of one or more target biometric matchers. NIST addressed this problem in August 2004 when it issued the NIST Fingerprint Image Quality algorithm, which was designed to be

Biometric Standards Program and Resource Center

Summary: Supporting the national strategy on biometrics and the development of required biometric standards is the cornerstone of our program. We seek to help the U.S. government and private sector meet their needs for high performance/highly secure interoperable biometric-based personal

Biometric Usability

Ongoing
The Visualization and Usability Group conducting research on the usability of biometrics. With the plans for integrating biometrics into many areas of government and public life, the importance of usability research has increased. We hope this site can broaden the awareness of what usability

Biometrics

With the need for improved homeland security, biometrics were identified as a key enabling technology. NIST (because of its mission and track record) supports the government-wide effort to increase the collection of good quality biometrics, to see that the data collected is appropriately shared with

Biometrics Web Services (BWS)

Ongoing
News A WS-Biometric Devices Walkthrough is now available. This document provides step by step instructions to develop a WS-BD web camera service. NBIS.Net 5.0.0 is available. This release provides access to NBIS 5.0.0 functionality from within any .Net language. NIST has published an updated

Biomolecular assembly

Ongoing
The integration of new materials or components into the design and production of diverse nanotechnologies, ranging from electronic devices to therapeutic particles, requires a quantitative understanding of process–structure–property relationships, as well as interactions with other entities in the

Bioprocessing Laboratory

Ongoing
Current Capabilities Computer controlled liquid nitrogen biostorage system Two culture areas including 4 monitored CO2 incubators 2 Six-foot BSLII biosafety cabinets Measurements- cell count and concentration, STR typing, flow cytometry, cell volume size distribution, conventional transmission and

Biosecurity for Synthetic Nucleic Acid Sequences

Ongoing
Emerging biotechnology, enabled by the ability to genetically engineer biological systems similar to the way we write software and program computers, can provide solutions to many pressing societal needs related to health, food security, supply chain resilience, and job growth for economic and

Biosurveillance and Pathogen Detection

Ongoing
NIST has established partnerships with other federal agencies to develop standards and measurement solutions to support biosurveillance. These efforts are supported in part through interagency agreements with partner agencies listed below to address their standards needs. PROGRAMS Standards for

Birefringence Properties of Optical Materials (0.12 μm – 2 μm)

Ongoing
For crystals with non-cubic crystal symmetry, we make accurate measurements of the birefringence and its wavelength dispersion (0.12 μm – 15 μm) by separate index measurements of the two polarizations using the NISTs minimum deviation refractometry system. In nominally isotropic materials (cubic

Boulder Microfabrication Facility

Ongoing
The Boulder Microfabrication Facility (BMF) is a 1700 m 2 (18,000 ft 2), ISO class 5 (class 100) clean room dedicated to providing state-of-the-art micro- and nano-fabrication capabilities to meet the microelectronic and microelectromechanical systems needs of NIST-Boulder staff members and their

Bringing the SI to Global Atmospheric Greenhouse Gas Measurement

Ongoing
This multifaceted program leverages expertise in three complementary technical focus areas- all of which involve SI-traceable measurements of relevant atmospheric species such as carbon dioxide, methane, water vapor and oxygen. The efforts include gravimetrically based preparation of primary

Broadband Coherent Anti-Stokes Raman Scattering (BCARS) Microscopy

Ongoing
Impact There is a need for label-free chemical microscopy in medicine, biology and materials science. Most of the current methods use chemical labels that often disturb the distribution and nature of chemical components being investigated. The method we are developing enables noninvasive and rapid

Broadband Large-Scale Modeling for Wireless

Ongoing
The objective of this project is to advance the state of the art in measurement and modeling of high frequency wireless systems and components under large signal conditions. Develop and verify a standard nonlinear device with large-signal response that can be predicted from underlying physical

Building Integration with Smart Grid

Ongoing
Objective - To develop the measurement science for industry standards that will enable interconnection of home and building automation and control systems with a future "smart" utility grid, provide consumers with energy usage information, and support industry efforts to develop the needed standards

Building Joint Sealant Service Life Prediction

Ongoing
The primary building sealant problem is that no method exists to provide high quality data for elucidating the relative importance of the k = 4 major weathering factors: X1: temperature, X2: humidity, X3: ultra-violet radiation, and X4: mechanical loading(and interactions) on the change in pre

Building Measurement Confidence for Cell Characterization

Ongoing
NIST collaborates with key stakeholders in industry, other government agencies, and academia to develop measurement assurance strategies and advanced measurement capabilities for cell characterization. Data and concepts developed through workshops and laboratory programs inform the development of

Building the next generation reference reflectometer

Ongoing
Have you ever wondered why some objects appear glossy, and others diffuse? Or thought about the complexity of characterizing the way light reflects from an object under different illumination and viewing angles and at different wavelengths in order to realistically render it in a computer simulation

Building-Level Seismic Performance Assessment

Ongoing
Objective: To better understand the seismic performance of buildings designed in areas of medium-to-high seismicity and to identify ways to create enhanced performance through low-damage approaches, improved code provisions, and improved analysis procedures. What is the Problem? Despite progress

Calculation of optical constants and dielectric response

Ongoing
By optical properties, we mean those of the following sort: the index of refraction n and the index of absorption k, from which one can calculate the dielectric function, loss function, absorption coefficient, reflectance, and so forth from standard formulas. All of these quantities, it should be

Calibration of Force Transducers

Ongoing
The calibration report describes the relationship between the applied force and the measured deformation, either in electrical or mechanical units. A transducer can be calibrated using (1) a readout device furnished by the customer, in which case the transducer and the readout device are calibrated

Calibration of Mass Standards

Ongoing
Redefinition of the Kilogram and Consensus Value of the Kilogram The unit of mass was redefined in May 2019 as part of a general revision to the International System of Units (SI). See SI Redefinition. The kilogram is now defined by the Planck constant. The International Prototype Kilogram (IPK) no
