Characterization and Reduction of Unexplained Noise in Superconducting Transition-Edge Sensors

May 7, 2004
Author(s)
Joel N. Ullom, William B. Doriese, Gene C. Hilton, James A. Beall, Steven Deiker, William Duncan, S. L. Ferreira, Kent D. Irwin, Carl D. Reintsema, Leila R. Vale
The noise in superconducting Transition-Edge Sensors (TESs) commonly exceeds simple theoretical predictions. The reason for this discrepancy is presently unexplained. We have measured the amplitude and frequency dependence of the noise in TES sensors with

Improving the Usability and Accessibility of Voting Systems and Products

May 7, 2004
Author(s)
Sharon J. Laskowski, James H. Yen, Marguerite W. Autry, J Cuginin, William H. Killam
The goal of this report is to describe how research and best practices from the human factors, human-machine and human-computer interaction, and usability engineering disciplines can be brought to bear to improve the usability and accessibility of voting

Performance Analysis of Next-Generation LADAR for Manufacturing, Construction, and Mobility

May 6, 2004
Author(s)
William C. Stone, Maris Juberts, Nicholas Dagalakis, Jack A. Stone Jr., Jason J. Gorman
The NIST Construction Metrology and Automation Group (CMAG), in cooperation with the NIST Intelligent Systems Division (ISD), is developing performance metrics and researching issues related to the design and development of a Next-Generation LADAR (laser

Test Environment and Procedures for Testing dd Provided With FreeBSD 4.4

May 6, 2004
Author(s)
James R. Lyle
This document describes the testing of dd in the FreeBSD environment. The test cases that were applied are described in Disk Imaging Tool Specification, Version 3.1.6.The tests were run on test systems in the Computer Forensics Tool Testing Lab at the

IPPS: An Integrated Process Planning System

May 4, 2004
Author(s)
Suber Huang, J Mei, Xuhang Tong, Steven R. Ray
The past two decades have witnessed the development of many CAPP (Computer-Aided Process Planning) systems. From variant process planning to generative process planning, great progress has been made. However, due to the complexity of the problems involved

Cryogenics on a Chip

May 3, 2004
Author(s)
Jukka Pekola, Rob Schoelkopf, Joel Ullom
Low-temperature techniques often bring to mind cryogenic liquids, gas compressors, and massive installations. But researchers are now building refrigerators and sensors that work by controlling electrons on a silicon chip.

A chromium surface magneto-optical trap for magnetic microtrap studies

May 1, 2004
Author(s)
M Pichler, S Hill, Jabez J. McClelland
A surface magneto-optical trap for chromium atoms is demonstrated as a first step toward loading atoms into microscopic magnetic traps. Characteristics of the trap and transfer to microscopic magnetic traps will be discussed.

An Operator-Independent Approach to Mass Spectral Peak Identification and Integration

May 1, 2004
Author(s)
William E. Wallace, Anthony J. Kearsley, Charles M. Guttman
A mathematical algorithm is presented that accurately locates and calculates the area beneath mass spectral peaks using only reproducible mathematical operations and a NO user-selected sensitivity parameters. This represents a major refinement of last year
