Design and Workspace Analysis of a 6-6 Cable-Suspended Parallel Robot

October 1, 2003
Author(s)
JJ Pusey, A Fattah, S K. Agrawal, Elena R. Messina, Adam S. Jacoff
In this paper, we study the design and workspaceof a 6-6 cable-suspended parallel robot. Theworkspace volume is characterized as the set ofpoints where the centroid of the moving platformcan reach with tensions in all suspension cables at a constant

Development of an Optical Fiber-Based Moisture Sensor for Building Envelopes

October 1, 2003
Author(s)
William M. Healy, S Luo, M Evans, A Sucheta, Y Liu
Optical fiber-based moisture sensors have been developed to help detect moisture problems in building envelopes. The sensors are created with a coating on a long period grating that is written onto optical fiber. As the coating absorbs moisture from its

Droplet-String Deformation and Stability During Micro-Confined Shear Flow

October 1, 2003
Author(s)
Jai A. Pathak, Kalman D. Migler
We have performed experiments on model emulsions of polyisobutylene (PIB) and poly(dimethylsiloxane) (PDMS) to quantify the effect of confinement on deformation and stability of droplets and strings (threads) under flow. It is known from some of our

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
