Research on Statistical Methods Project

Ongoing
The division typically produces one to a few publications on new statistical methods each year. A list of publications on some research from the past few years is shown below below. Following the publication list, an example of current work on the development of novel statistical methods, useful

SED Consulting Program

Ongoing
Description: Specific SED contributions include: Leadership in the establishment of a high standard of statistical practice within NIST via interactions with technical staff, publications, workshops, and seminars. Design and analysis of experiments, and evaluation of measurement uncertainties for

Short Courses

Ongoing
Staff members of the Statistical Engineering Division regularly offer short courses on uncertainty analysis, design of experiments, and other topics in statistical metrology at NIST, at conferences open to the public, and at other government agencies. Prospective attendees of short courses at NIST

Smart Grid Communication Networks

Ongoing
Objective: To accelerate the development of scalable, reliable, secure, and interoperable communications and standards for smart grid applications; and to enable informed decision making by smart grid operators by developing measurement science-based guidelines and tools. What is the new technical

Software and Data Carpentry

Ongoing
Software and Data Carpentry workshops conduced at NIST are designed to teach basic computing and data skills that enable NIST researchers to get more done in less time, while also making it easier to automate and document research workflows. These skills can allow for more rapid and reliable

Speaker and Language Recognition

Ongoing
Current Speaker and Language Recognition technology activities: Speaker Recognition Evaluation series: (1996-) A biennial NIST evaluation of fully automated text-independent speaker recognition technology. View the 2012 NIST SRE report. Human Assisted Speaker Recognition Evaluation series: (2010- )

Speech Analytics

Ongoing
Current speech analytics work: OpenSAT is a new speech analytic evaluation series designed to include developers from multiple speech analytic technologies where common datasets are used in NIST evaluations. The goal is to bring together developers focused on different speech analytic tasks to

Statistical Characterization of High-Speed Oscilloscopes and Photodiodes

Ongoing
As part of a interdisciplinary team including staff from the Optoelectronics and the Radio Frequency Technology Divisions of EEEL, SED staff are developing statistical methods and associated software for calibration of high-speed digital sampling oscilloscopes and characterizing the impulse response

Statistical Education Project

Ongoing
The NIST laboratory has over 1300 scientists and engineers formulating investigations, planning experiments, collecting data, analyzing data, and deriving scientific/ engineering conclusions. All of these scientific-method components may benefit from both the general and NIST-specific statistical

Statistical Methods in Millimeter-Wave Wireless Metrology

Ongoing
DESCRIPTION: One of the measurement solutions is the use of reverberation chambers for free-field testing of wireless devices. A reverberation chamber is an environment for electromagnetic compatibility testing and other investigations. Quantities of interest that have been studied for wireless

Statistical Methods for Quantitative Imaging

Ongoing
In this project, we have gained valuable experience in the emerging area of developing metrology support for medical image decision making, and we have focused mainly in the area of high resolution CT imaging for lung nodules,using both phantoms and clinical data, in the context of RSNA's QIBA

Statistical Methods in Waveform Metrology

Ongoing
One of the methods developed is the timebase correction procedure for waveforms. A waveform is a representation of a signal varies with time. The most familiar waveform is the sine wave. Waveform measurements are required throughout the optical communications, computer, wireless communications

Statistical Process Monitoring for Autocorrelated Data

Ongoing
DESCRIPTION: Process monitoring is very important for industries. Statistical methodologies have been used to monitor various production process successfully. The majority of statistical process monitoring techniques assume that the process data are free of autocorreation. However, this assumption

Statistical Support for Bioassay Standard Development

Ongoing
Biological assays are procedures that can determine concentration, purity, or biological activity of a substance through scientific experimentation. Fluorescence-based quantification one of the most widely used technique in quantitative clinical and biochemical assays, and it depends on the

Statistics for Ballistics Identification

Ongoing
DESCRIPTION: Statistical Engineering Division has had an ongoing collaboration with NIST's Precision Engineering Division (now Semiconductor and Dimensional Metrology Division) and Office of Law Enforcement Standards (now in the Office of Special Programs) in the field of firearms and tool mark

Strategies for Testing Embedded Software

Ongoing
The objective of this project is to develop efficient new testing strategies for devices following a model outside the usual non-software-embedded framework using the concept of Expectation Maximization (EM). The EM approach is attractive because it would provide an efficient method for extending

Surrogate Gas Prediction Model

Ongoing
DESCRIPTION: Since fossil fuels are devoid of 14C, the measured 14C ratio of atmospheric CO 2 (expressed as Delta-C) is the gold standard measurement to determine the fossil fuel enhancement, C ff, to any atmospheric CO 2 measurement. With enough Delta-C measurements, independent, "top-down"

Text Analysis Conference

Ongoing
Mission TAC's mission is to support research within the Natural Language Processing community by providing the infrastructure necessary for large-scale evaluation of NLP methodologies. TAC's primary purpose is not competitive benchmarking; the emphasis is on advancing the state of the art through

Text REtrieval Conference (TREC)

Ongoing
Its purpose was to support research within the information retrieval community by providing the infrastructure necessary for large-scale evaluation of text retrieval methodologies. In particular, the TREC workshop series has the following goals: to encourage research in information retrieval based

TREC Video Retrieval Evaluation: TRECVID

Ongoing
The TREC conference series is sponsored by the National Institute of Standards and Technology ( NIST) with additional support from other U.S. government agencies. The goal of the conference series is to encourage research in information retrieval by providing a large test collection, uniform scoring

Tunable Compression of Wind Tunnel Data

Ongoing
Variability of Bending Moments The values of the bending moments vary both within each run, and between runs. The between-runs variability provides a standard against which one should assess the severity of any loss of information that a data compression scheme may incur. To assess it, we fitted a
