International Evaluation Collaboration: Developing and Managing Infrastructure for Research and Development Programs

Author(s)

Rachel J. Bowers, Dennis Moellman, John S. Garofolo

The most innovative technology can potentially meet any goals of research sponsors. However, this potential may never materialize if the program lacks infrastructure. Although most new programs address basic contractual and managerial components, often few

Is Bonds Out

Author(s)

Robert C. Hagwood

In this paper, the cumulative home run rates of the 20 players with 500 or more home runs are analyzed. We show that Bonds and McGwire have cumulative totals that lie statistically outside the others in the study.

Making Ballot Language Understandable to Voters

Author(s)

Sharon J. Laskowski, Janice G. Redish

The wording and placement of instructions can help or hinder voters from successfully voting for their choices. No research has been done specifically on the language of instructions to voters, but we can draw best practices from research in several

Metrology and process control: dealing with measurement uncertainty

Author(s)

James E. Potzick

Metrology is often used in designing and controlling manufacturing processes. A product sample is processed, some relevant property is measured, and the process adjusted to bring the next processed sample closer to its specification. This feedback loop can

Microsecond-Resolution Laser Polarimetry for the Measurement of the Normal Spectral Emissivity of Pulse-Heated Materials

Author(s)

Sitaraman Krishnan, K Boboridis

The design and operating principles of a new laser polarimeter system capable of microsecond-resolution measurements of the polarization state of light and of optical properties of solid and liquid materials, including the normal spectral emissivity, are

Author(s)

Richard A. Messerly, Michelle C. Anderson, S. M. Razavi, J. R. Elliott

In response to the 10th Industrial Fluid Properties Simulation Challenge, we report viscosity (eta) estimates of 2,2,4-trimethylhexane at 293 K for a range of pressures (P) from 0.1 MPa to 1000 MPa. The Potoff force field is utilized in this study, as a

Moving With Metric (draft title--metric system cube)

Author(s)

P A. Wolf

This information cube promotes the International System of Units (SI), or the metric system.The SI is the dominant system of measurement units worldwide. Developed by the French in the late 18th century, the system has been refined by international

Since 1987, the National Institute of Standards and Technology has been providing evaluation infrastructure for the Automatic Speech Recognition (ASR), and more recently referred to as the Speech-To-Text (STT), research community. From the first efforts in

Nanoparticle Release from Polymer Nanocomposites Used for Potable Water Infrastructure and Food Packaging: Current Progress & Beyond

Author(s)

Andrew Whelton, T.V. Duncan , J.L. Koontz , Tinh Nguyen

Nanoparticle (NP) enhanced polymers have the potential to revolutionize food packaging and water pipe performance, though release from these materials has gone relatively unstudied. A literature review was conducted to identify potential NP release

New NIST-traceable Standards for Calibration and Validation of Differential Scanning Calorimetry

Author(s)

Donald G. Archer

Several reference materials and associated reference values have been recommended for the purposes of calibration and/or validation of differential scanning calorimetry (DSC). However, issues of available sample purity, reference-property value accuracy

NIST Cloud Computing Program Supporting the U.S. Cloud Computing Strategy

Open-Source Excel Tools For Statistical Metrology

Author(s)

Hung-Kung Liu, William F. Guthrie, Juan Soto

In this paper we introduce an approach to construct statistical metrology tools with a Microsoft Excel based interface that use the open source statistical package R as the computational engine. These metrology tools will enable Excel users to access a

Optical trapping of selected dielectric microparticles in air

Author(s)

Haesung Park, Thomas W. LeBrun

We demonstrate a method to trap a selected dielectric microparticle in air using radiation pressure from a single-beam gradient optical trap. Randomly scattered dielectric microparticles adhered to a glass substrate are momentarily detached using

Random Walk Approach to Uniqueness and Mixing Conditions in Markov Random Fields

Author(s)

Antonio M. Possolo, Andrew L. Rukhin

This note gives an interpretation of Dobrushin?s conditions for uniqueness and mixing Markov field in terms of a random walk with an absorbing state. An example involving Ising?s lattice gas model is discussed, and a version of the Central Limit Theorem is

Receiver Sensitivity in CSMA Networks

This paper aims at improving the power efficiency of the CSMA/CA protocol for transmission of multimedia information over multihop wireless channels. Using a distance dependent propagation model, we present a power control scheme, which is based on the

REDUCING THE UNCERTAINTY IN A MEASURE OF THE ACCELERATION OF GRAVITY FOR THE ELECTRONIC KILOGRAM

Author(s)

Richard L. Steiner, Beatrice Parker

Calculating the force on a reference mass for the electronic kilogram experiment requires using both absolute and relative gravity meters to measure the acceleration of gravity. Tests have been conducted to achieve an uncertainty of less than 1 part in 108
