Guidelines for Using Color in Voting Systems

October 23, 2008
Author(s)
Maureen Stone, Sharon J. Laskowski, Svetlana Z. Lowry
This document is a digital color design guide for the electronic displays of voting systems. It encodes best practice for usability in general, and specifically to accommodate a wide range of color vision deficiencies. Systems that follow these guidelines

October 22, 2008
Author(s)
Matthew A. Scholl, Kevin Stine, Joan Hash, Pauline Bowen, L A. Johnson, Carla Dancy Smith, Daniel Steinberg
Special Publication 800-66 Rev. 1, An Introductory Resource Guide for Implementing the Health Insurance Portability and Accountability Act (HIPAA) Security Rule, which discusses security considerations and resources that may provide value when implementing

Collective dynamics in the Heisenberg pyrochlore antiferromagnet Gd 2 Sn 2 O 7

October 22, 2008
Author(s)
J. R. Stewart, Jason Gardner, Yiming Qiu, G. Ehlers
Gd2Sn2O7 is believed to be a good approximation to a Heisenberg antiferromagnet on a pyrochlore lattice with exchange and dipole-dipole interactions. The system is known to enter a long-range ordered ground state (the "Palmer Chalker" state) below Tc = 1 K

Establishment of the SIM Time Scale

October 22, 2008
Author(s)
Michael A. Lombardi, Nelida Diaz-Munoz, J. Mauricio Lopez-Romero
The SIM time and frequency metrology working group has developed a comparison network for the Americas, with the goals of improving metrology in the SIM region by allowing as many countries as possible to participate in the network. As of May 2008, 10

Organic single crystal field-effect transistors of a soluble anthradithiophene

October 22, 2008
Author(s)
Oana Jurchescu, Sankar Subramanian, R J. Kline, Steven D. Hudson, John E. Anthony, Thomas Jackson, David J. Gundlach
We use single crystals (grown by physical vapor transport) of a soluble oligomer to obtain a better understanding of the intrinsic properties, limitations and potential of these materials. Single crystals are well-suited for studies exploring the effects

Hydraulically Pumped Cone Fracture in Brittle Solids

October 21, 2008
Author(s)
Herzl Chai, Brian R. Lawn
An analysis of inner cone cracks in brittle solids subject to cyclic indentation in liquid is presented. These inner cone cracks, so named because they form well within the maximum contact circle, are postulated to be driven by a hydraulic pumping

Aqueous blackbody calibration source for millimeter-wave/terahertz metrology

October 20, 2008
Author(s)
Charles Dietlein, Zoya Popovic, Erich N. Grossman
This paper describes a calibrated broadband emitter for the millimeter-wave through terahertz frequency regime, called the aqueous blackbody calibration source. Due to its extremely high absorption, liquid water is chosen as the emitter on the basis of

A COMPACT, COMPOUND ACTUATOR FOR THE MOLECULAR MEASURING MACHINE

October 19, 2008
Author(s)
Jing Li, Yin-Lin Shen, Jaehwa Jeong, Fredric Scire, John A. Kramar
A compact, two-stage, vertical actuator with built-in sensors has been developed for the Molecular Measuring Machine (M3) and other potential precision instrumentation applications, such as scanning probe microscopy (SPM). In this article, we describe the

Comparison of NIST SI Force Scale to NPL SI Mass Scale

October 19, 2008
Author(s)
Christopher W. Jones, John A. Kramar, Stuart Davidson, Richard Leach, Jon R. Pratt
Small masses in the 1.0 mg to 0.1 mg range were developed and calibrated at NPL with traceability to the IPK. These masses were transported to NIST at Gaithersburg and used as deadweights on the NIST electrostatic force balance, to facilitate a mass-force

Error Motions of a Non-orthogonal Rotary Axis

October 19, 2008
Author(s)
Michael L. McGlauflin, Shawn P. Moylan
Error-motions of rotating axes are one of many sources of imprecision in machining. Accurate determination of axis of rotation error motions of the rotary axes has a direct influence on the accuracy of the finished part. International and U.S. national

A New Spin on the Doppler Effect

October 17, 2008
Author(s)
Mark D. Stiles, Robert D. McMichael
The coupling between ferromagnetism and electrical current has recently been the object of intense study because of the combination of interesting scientific developments and the potential technological impact. This coupling is mediated by spin current

Cooling Mode Fault Detection And Diagnosis Method For A Residential Heat Pump

October 17, 2008
Author(s)
Minsung Kim, Seok H. Yoon, William V. Payne, Piotr A. Domanski
Performance characteristics of a R410A residential unitary split heat pump equipped with a thermostatic expansion valve (TXV) were investigated in the cooling mode under no-fault and faulty conditions. An automated method of steady-state detection was

High Performance Organic Thin-Film Transistors Made Simple Through Molecular Design and Processing

October 17, 2008
Author(s)
Oana Jurchescu, Marina Feric, Behrang H. Hamadani, M. Devin, Sankar Subramanian, Balaji Purushothamanc, John E. Anthony, Thomas Jackson, David J. Gundlach
We report on a simple a method of inducing self-isolation of the thin film transistors via manipulation of the chemical interactions between the organic molecules and the surfaces where they are deposited. We use pentafluorobenzenethiol (PFBT) treatment of

International photomask linewidth comparison by NIST and PTB

October 17, 2008
Author(s)
James E. Potzick, Ronald G. Dixson, Richard Quintanilha, Michael T. Stocker, Andras Vladar, Egbert Buhr, Bernd Bodermann, Wolfgang Hassler-Grohne, Harald Bosse, C.G. Frase
In preparation of the international Nano1 linewidth comparison on photomasks between 8 national metrology institutes, NIST and PTB have started a bilateral linewidth comparison in 2008, independent of and prior to the Nano1 comparison in order to test the

Standardization of Auxiliary Equipment for Next Generation CNC Machining

October 17, 2008
Author(s)
David Odendahl, Sid Venkatesh, John L. Michaloski, Frederick M. Proctor
This paper presents the recent work of the Open Modular Architecture Control (OMAC) Machine Tool Working Group to support STEP-NC, which is a new standard for the exchange of comprehensive Computer Numerical Control (CNC) manufacturing data. Because of the

The Origins of Random Telegraph Noise in Highly Scaled SiON nMOSFETs

October 17, 2008
Author(s)
Jason P. Campbell, Jin Qin, Kin P. Cheung, Liangchun (. Yu, John S. Suehle, A Oates, Kuang Sheng
Random telegraph noise (RTN) has recently become an important issue in advanced circuit performance. It has also recently been used as a tool for gate dielectric defect profiling. In this work, we show that the widely accepted model thought to govern RTN
