Advanced Fluid Characterization - Laboratory Information Management System

Ongoing
Breath sampling of cannabis users. I n July 2019, the National Institute of Justice awarded our team funding for a three-year project to provide the chemical foundation for industry to develop a cannabis breathalyzer. We are developing new experimental methods to enhance the clinical, thermodynamic

Advanced Microwave Radiometer Metrology

Ongoing
Using the NIST radiometer as a test bed, we studied the stability of temperature measurements for infrequent calibrations and developed stability metrics. We developed models to simulate output temperatures from the NIST radiometer, thus enabling the study of radiometer output without having to

Bayesian Metrology Project

Ongoing
Research, develop, and apply Bayesian methods to the metrological problems of NIST; promulgate results to other metrology laboratories and to NIST customers. Four specific areas are targeted: traceability, interlaboratory comparisons, calibration, and part inspection. These areas were chosen because

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

Cement Characteristics by Direct Phase Assessment

Ongoing
DESCRIPTION: The major research goal is the accurate prediction of field performance metrics from accurate characterization of mineralogical composition and texture. Compounding characterization and prediction problems is the widespread reliance since the 1930's on the Bogue estimates of composition

Charpy Impact Machine Verification Program

Ongoing
The low cost and simple configuration of the test have made it a common requirement in codes for critical structures. However, the test is not useful if the variation in test results between laboratories is not tightly controlled. The control is accomplished by requiring the indirect verification of

Clutter Measurement

Ongoing
The Irregular Terrain Model (ITM) is a model for radio propagation that has been widely used for predicting the attenuation of a radio signal as a function of distance and the variability of the signal in time and in space. It was developed in the 1960 sand therefore does not fully utilize the

Collaborative Research with NIST Scientists and Engineers

Ongoing
As members of interdisciplinary teams, SED statisticians contribute in a variety of ways. SED staff develop appropriate statistical strategies to meet the needs of the research teams, participate in the planning of experimental studies, and conduct rigorous and nontrivial uncertainty analysis of

Combinatorial Testing

Ongoing
For more information regarding the Combinatorial Testing, please visit the Computer Security Resource Center (CSRC)..

Comparative Mammalian Proteome Aggregator Resource (CoMPARe) Program

Ongoing
Comparative proteomics strives to gain insight into key underlying molecular changes that result in unique phenotypes across related taxa. Proteomic analysis complements comparative genomics by providing evidence of protein abundance, orthogonal to gene copy number and amount of transcript. To

Comparative Serum Proteomics Project

Ongoing
State-of-the-art biomolecular analysis is no longer limited to model organisms and is becoming routine in non-model organisms. Major drivers of this emerging bioanalytical capacity include increasing accessibility and quality of sequenced genomes as well as high-resolution fast-duty cycle mass

Consistency Analysis and Uncertainty in ‘omic Data

Ongoing
‘Omics is increasingly moving out of the laboratory and towards use in industrial and commercial applications. For instance, in biomanufacturing, there is a need for quality control when developing biotherapeutics, which will almost certainly require a machine-learning classifier to separate

Content-Based Access to Unstructured Information

Ongoing
The goal of the project is to support the development of automatic systems that can provide content-based access to information that has not been explicitly structured for machine consumption. This support is in the form of evaluation infrastructure, since to quote Lord Kelvin, "If you can not

Critical Current Metrology

Ongoing
PML staff have completed the construction and testing of a variable-temperature and variable-strain, or unified, apparatus for measuring critical current. The apparatus combines world class capabilities in variable-temperature and variable-strain measurements and is expected to be the highest

Data Science

Ongoing
Current MIG Data Science project activities DARPA D3M. NIST is supporting the DARPA D3M (Data-Driven Discoveries of Models) program as part of the Test and Evaluation (Government) Team. The D3M Program aims to allow automated systems with subject matter experts to model and solve complex machine

Density Functional Tight Binding Methods

Presently the study by quantum chemistry techniques of large (several thousands of atoms) molecular systems is limited by large computer time and space (memory, disk) requirements. The required time, memory, and disk space to solve the requisite equations typically increase exponentially with the

Design and Analysis of Key Comparisons

Ongoing
DESCRIPTION: With the recent signing of the Mutual Recognition Arrangement (MRA), National Metrology Institutes (NMI's) and Regional Metrology Organizations (RMO's) around the world have committed themselves to establishing the equivalence of their measurement standards. Currently, however, there is

Detecting Change Points in Surface Temperature Records

Ongoing
DESCRIPTION: For the purpose of exposition, consider the record daily minimums averaged by month for a station near Reno Nevada. There is a clear drop in the level between 1920 and 1940 and a positive drift starting at about 1980. There is also however, considerable variability due to seasonal

e-Statistics

Ongoing
DESCRIPTION: e-FITS is a web-based tool, currently available to NIST staff, used to perform the following tasks for over 100 probability distributions. Generate graphs of probability functions (probability density, cumulative distribution, inverse cumulative distribution, hazard, cumulative hazard

Experimental Evaluation of Large-Scale Parallel Measurement Systems

Ongoing
DESCRIPTION: An archetype among biological experiments is gene-by-gene determination of the expression difference between two groups of biological units. For each gene, the experiment yields a data set consisting of one or more expression values for each unit. Gene to gene, these data sets can be

Functional Analysis of Variance

Ongoing
Assessment of measurement data often raises statistical inference questions which have not been adequately addressed in the statistical literature. For example, NIST scientists may encounter issues on whether two measurement techniques give arise to similar measurement curves, whether there is a

Genome in a Bottle

Ongoing
Consortium goals: The Genome in a Bottle Consortium is a public-private-academic consortium hosted by NIST to develop the technical infrastructure (reference standards, reference methods, and reference data) to enable translation of whole human genome sequencing to clinical practice and innovations
