Analysis of Wasp Waist Hysteresis Loops

January 3, 2005
Author(s)
Lawrence H. Bennett, Edward Della Torre
Wasp-waist and pot belly hysteresis loops have been observed in many materials. When only the major loop is reported, the results are insufficient to establish which processes are involved. We present two models for wasp waist materials that produce

Effect of Magnetic Field Dynamics on Thermocouple Performance

January 3, 2005
Author(s)
F Shir, Lawrence H. Bennett, C Mavriplis
There are challenges in measuring temperature by thermocouples in a time-dependent magnetic field. Although there is considerable experience of the effect of a steady magnetic field, there is a lack of awareness of the outcome of a varying field on

New Generation of the NIST Atomic Spectroscopic Databases

January 3, 2005
Author(s)
Y Ralchenko, Jeffrey R. Fuhr, F C. Jou, Alexander Kramida, William C. Martin, Larissa Podobedova, Joseph Reader, E B. Salomon, Jean E. Sansonetti, Wolfgang L. Wiese
The latest advances in development of atomic spectroscopic databases at the National Institute of Standards and Technology (NIST) result from implementation of modern technologies in database management and database-user interaction. Here we report a

NIST Time and Frequency Bulletin

January 3, 2005
Author(s)
Eyvon Petty
The Time and Frequency Bulletin provides information on performance of time scales and a variety of bradcasts (and related information) to users fo the NIST services.

Obstacle Detection using a TOF Range Camera* for AGV Safety and Navigation

January 3, 2005
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Rajmohan Madhavan
The performance evaluation of an obstacle detection and segmentation algorithm for Automated Guided Vehicle (AGV) navigation in factory-like environments using a 3D real-time range camera is the subject of this paper. Our approach has been tested

The Boundary of X-Ray and Electron Tomography

January 3, 2005
Author(s)
Zachary H. Levine
Samples a few micrometers in total size offer a challenge to both x-ray and electron tomography. X-ray tomography originated imaging the human body with millimeter resolution, but the resolution has been reduced by over 7 orders of magnitude by the use of

Workshop to Define Information Needed by Emergency Responders During Building Emergencies

January 3, 2005
Author(s)
Walter W. Jones, William D. Davis, D D. Evans, David G. Holmberg, Steven T. Bushby, K A. Reed
On May 3, 2004, NIST sponsored a workshop to identify the information needs for emergency responders. The purpose of this workshop was to obtain guidance on the type of building static and dynamic tactical information needed by public safety officials, how
