International Comparison of Surface Roughness and Step Height (Depth) Standards, SIM 4.8

January 1, 2006
Author(s)
K Doytchinov, F Kornblit, C C. Castellanos, J C. Oliveira, Thomas Brian Renegar, Theodore V. Vorburger
Calibration services of 5 countries from the SIM region are compared through measurements of surface roughness and step height standards. A surface roughness standard with a nominal Ra value of 0.2 mm, a surface roughness standard with a nominal Ra value

Joint Rate Adaptation and Channel-Adaptive Relaying in 802.11 Ad Hoc Networks

January 1, 2006
Author(s)
Michael R. Souryal, Nader Moayeri
Channel-adaptive relaying has recently been proposed as a means to exploit spatial and temporal diversity in multihop ad hoc networks with fading. In conjunction with appropriate routing protocols, adaptive relaying enables each forwarding node in a

Large-Scale Metrology Instrument Performance Evaluations at NIST

January 1, 2006
Author(s)
William T. Estler, Daniel S. Sawyer, Bruce R. Borchardt, Steven D. Phillips
The ASME B89 Committee on Dimensional Metrology has approved a new American National Standard B89.4.19 - Performance Evaluation of Laser Based Spherical Coordinate Measurement Systems. This Standard, to be published in 2006, specifies test methods for

Lessons From Simulation Regarding the Control of Synthetic Self-Assembly

January 1, 2006
Author(s)
Jack F. Douglas, K VanWorkum
We investigate the role of the particle potential symmetry on the form of self-assembly by Monte Carlo simulation with the particular view towards synthetically creating structures of prescribed form and function. We establish a general tendency for the
