Estimating Error Discovery in Library Conformance Testing

Author(s)
Gordon E. Lyon
Procedure libraries provide fresh insight into unit conformance testing. The library specification, as an ensemble, offers cost estimates for error discovery even prior to obtaining code to test. One extracts or decides counts of: (i) formal parameters for

ESTIMATING UNCERTAINTY LIMITS IN THE NIST-2008 ELECTRONIC KILOGRAM

Author(s)
Richard L. Steiner, Edwin R. Williams, Ruimin Liu, Beatrice Parker
The NIST electronic kilogram has had three published results, each with slightly less uncertainty. In the present design, there are several measurement components that have uncertainties that are difficult to reduce further. These limiting uncertainties

Feedback control of a nonlinear electrostatic force transducer

Author(s)
Ivan Ryger, Stefan Chamraz, Richard Balogh, Alexandra B. Artusio-Glimpse, Michelle S. Stephens, John H. Lehman, Paul A. Williams
In this article, we document a design process for a feedback controller for a nonlinear electrostatic transducer that exhibits a strong unloaded resonance. This is being used for precision optical power measurement by means of a photon force measurement

Framework for Performance Evaluation of Face, Text, and Vehicle Detection and Tracking in Video: Data, Metrics, and Protocol

Author(s)
Rangachar Kasturi, D Goldgof, K Soundararajan, V Manohar, M Boonstra, V Korzhova, J Zhang, Rachel J. Bowers, John S. Garofolo
Common benchmark datasets, standardized performance metrics, and baseline algorithms have demonstrated considerable impact on research and development in a variety of application domains. These resources provide both consumers and developers of technology

Green Fluorescent Protein in Inertially Injected Aqueous Nanodroplets

Author(s)
Jianyong Tang, Ana Jofre, G M. Lowman, Rani B. Kishore, Joseph E. Reiner, Kristian Helmerson, Lori S. Goldner, M E. Greene
individual hydrosomes into an immiscible solvent matrix composed of perfluorotriamylamine. Hydrosomes containing EGFP were optically trapped held at the focus of an excitation laser in a confocal microscope, and single molecule photobleaching events were

Handover-based Call Admission Control in Heterogeneous Wireless Networks

Author(s)
Nicolas Chevrollier, Nada T. Golmie, Nicolas Montavont
With the need for mobility comes stringent quality of service requirements that have to be met before users are able to roam seamlessly across different network infrastructures. In this paper we investigate the use of a handover-based call admission

Improvements in the Winkler Titration for Iodide in Iodized Salt

Author(s)
Kenneth W. Pratt, Karen E. Murphy
A bromine gas generator, based on bleach, potassium bromide and dilute hydrochloric acid, replaces hazardous pure bromine used in the classical Winkler titration for iodide. This modification eliminates the need to store or use pure bromine. The gas

Influence of Aggregate Properties on Concrete Mechanical Performance

Author(s)
Jussara Tanesi, Dale P. Bentz, Scott Z. Jones, Mengesha Beyene, Haejin Kim, Ahmad Ardani, Paul E. Stutzman
While the influence of paste properties on concrete performance has been extensively studied, that between aggregate characteristics and concrete performance has not been investigated in detail. Based on previous research that demonstrated significant

Inter-comparison Example

Author(s)
Adriana Hornikova, Maritoni A. Litorja, Stefan D. Leigh, J B. Fowler
This paper overviews results from Consultative Committee on Photometry and Radiometry (CCPR) the Supplementary Comparison S2. It details measurement and analysis of aperture areas involving 9 laboratories using 8 distinct artifacts, each having a different

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.

JCGM-WG1-SC1-N88 -- Comments

Author(s)
Antonio M. Possolo
Comments on Clemens Elster's contribution to the Working Group 1 of the Joint Committee for Guides in Metrolgy, BIPM, entitled "Calculation of uncertainty in the presence of prior knowledge" (2007, Metrologia, Volume 44 (2007), Pages 111-116), showing how

JCGM-WG1-SCO-N13 -- Comments

Author(s)
Antonio M. Possolo
Comments on the Draft of Supplement 0 to the Guide to the Expression of Uncertainty in Measurement (GUM), to be discussed during the April 2007 meeting of Working Group 1 of the Joint Committee for Guides in Metrolgy, BIPM, in Sevres, France.

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

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
