Electrostatic Influence on Ion Transport through the alpha HL Channel

October 1, 2003
Author(s)
M Misakian, John J. Kasianowicz
The current-voltage relationship of a single Staphylococcus aureus α-hemolysin(αHL) channel is nonlinear, rectifying, and depends on the bulk pH and the ionic strength. The data are described qualitatively by a simple one-dimensional Nernst-Planck analysis

Flexible Manufacturing System for Mass Customization Manufacturing

October 1, 2003
Author(s)
Guixiu Qiao, R F. Lu, Charles R. McLean
Mass customization manufacturing (MCM) has been gaining recognition as an industrial revolution in the 21st century. This paper presents innovative approaches in realizing and exercising MCM in theoretical and practical applications. Strategies of

From Data to Outcomes: Assessment activities at the NIST Research Library

October 1, 2003
Author(s)
Barbara P. Silcox, P J. Deutsch
The Research Advisory Committee (RAC) at the National Institute of Standards and Technology (NIST) in its 2000 Annual Report to the NIST Director expressed concern that the NIST Research Library would not be able to meet the research needs of the

From Data to Outcomes: Assessment Activities at the NIST Research Library

October 1, 2003
Author(s)
Barbara P. Silcox, P J. Deutsch
This is the third and final article in a series describing assessment activities at the National Institute of Standards and Technology (NIST) Research Library. The first article described the development, administration, and interpretation of a customer

Human Identification from Body Shape

October 1, 2003
Author(s)
Afzal A. Godil, Patrick J. Grother, Sanford P. Ressler
In this paper, we investigate the utility of static anthropometric distances as a biometric for human identification. The 3D landmark data from the CAESAR database is used to form a simple biometric consisting of distances between fixed rigidly connected

Impact of Natural Ventilation Strategies and Design Issues for California Applications, Including Input to ASHRAE Standard 62 and California Title 24-Report on Task 4.4.3a and 4.4.3b of CEC-EEB RMT Project

October 1, 2003
Author(s)
Steven J. Emmerich, Andrew K. Persily, William S. Dols, James W. Axley
Natural ventilation has the potential to reduce the energy required for cooling and ventilating commercial buildings while still providing acceptable thermal comfort and indoor air quality. While a recent surge of interest in Europe has advanced natural

Information-based Intelligent Unmanned Ground Vehicle Navigation

October 1, 2003
Author(s)
Rajmohan (. Madhavan, Elena R. Messina
Abstract?Sensor-centric navigation of Unmanned Ground Vehicles (UGVs) operating in rugged and expansive terrains requires the competency to evaluate the utility of sensor information such that it results in intelligent behavior of the vehicles. In this

Kinematics of the Sagittarius B2(N-LMH) Molecular Core

October 1, 2003
Author(s)
J M. Hollis, J A. Pedelty, D A. Boboltz, S Y. Liu, Lewis E. Snyder, Patrick Palmer, Francis J. Lovas, P R. Jewell
Ethyl cyanide (CH3CH2CN) emission and absorption have been imaged with the Very Large Array toward Sagittarius B2(N-LMH) by means of the 5(15)-4(14) rotational transition at 43.5 GHz (lambda similar to mm). The 1.5 x 1.4 VLA beam shows two principal

Manufacturing Data Validation Through Simulation

October 1, 2003
Author(s)
Guodong Shao, Yung-Tsun Lee, Charles R. McLean
In order to ensure that the process plan and numerical control (NC) programs are complete and correct before jobs are released to the shop floor, manufacturing industry needs a validation system that has visualization and analysis capabilities. A prototype

Nanocrystal Molecules and Chains

October 1, 2003
Author(s)
J F. Diaz, W Jaskolski, J Planelles, Javier Aizpurua, Garnett W. Bryant
The electron energy structure of linear artificial molecules and one-dimensional chains formed of spherical semiconductor nanocrystals is investigated with and without and applied magnetic field. Both uniform and multilayer nanocrystals are studied. The

National Software Reference Library (NSRL)

October 1, 2003
Author(s)
Barbara Guttman
The National Software Reference Library (NSRL) of the U.S. National Institute of Standards and Technology (NIST) collects software from various sources and publishes file profiles computed from this software (such as MD5 and SHA-1 hashes) as a Reference
