Extremely Low Frequency Electric and Magnetic Field Measurement Methods

December 1, 1998
Author(s)
Martin Misakian
During the early 1970's, reports originating in the Soviet Union described a variety of ill effects experienced by personnel working in 500 kV and 750 kV switchyards [1,2],. The effects were attributed to the presence of the ac electric fields as well as

Finite Precision Representation of the Conley Decomposition

December 1, 1998
Author(s)
Fern Y. Hunt
We present the theoretical basis for a novel way of studying and representing the long time behavior of finite dimensional maps. It is based on the sample paths of a Markov chain. Applications of the method to the approximation of attractors of maps and to

Heat Transfer Analysis and Modeling of a Cryogenic Laser Radiometer

December 1, 1998
Author(s)
Brian E. Johnson, A. R. Kumar, Z M. Zhang, David J. Livigni, Christopher L. Cromer, Thomas Scott
This study investigates the laser optimized cryogenic radiometer (LOCR) recently acquired by the National Institute of Standards and Technology in Boulder, Colorado, to calibrate laser power meters and detectors.

Impediments to Software Engineering Technology Transfer

December 1, 1998
Author(s)
M V. Zelkowitz, D Wallace, D W. Binkley
Although the need to transition new technology to improve the process of developing quality software products is well understood, the computer software industry has done a poor job of carrying out that need. All toooften new software technology is touted

Indentation Creep Behavior of a Direct-Filling Silver Alternative to Amalgam

December 1, 1998
Author(s)
Hockin D. Xu, Kate Liao, F Eichmiller
Amalgam creep has been identified as a key parameter associated with marginal breakdown and corrosion. Recently, a consolidated silver powder was proposed as a mercury-free alternative to amalgam. The aim of the present study was to characterize the time
