Micromotion of ions in Paul traps has several adverse effects, including alterations of atomic transition line shapes, significatn second-order Doppler shifts...
A simplified ultrasonic immersion technique has been developed to measure leaky surface and bulk waves in solid materials by using specially designed lensless...
The International Union for Vacuum Science, Technique and Applications (IUVSTA) has established a workshop programme to provide a forum for intense scientific...
This work is one chapter of the 19th NFPA Fire Protection Handbook directed at giving the user simplified methods to estimate quantities used in fire protection...

We report on low-noise DC SQUID series arrays incorporating intracoil damping, which show smooth DC characteristics. The voltage-flux characteristics of these...
Increasing the power and speed of machining operations has several advantages. These include: [1] shorter machining time; [2] improved surface finish; [3]...
It has been shown previously that the solvation energies of small molecules can be computed to useful accuracy with continuum models of the solvent that...
This paper describes a system developed at NIST to produce a composite Automatic Speech Recognition (ASR) system output when the outputs of multiple ASR systems...
This paper suggests that one can use principal components analysis to assess the local dimensionality in a complex dataset. If this is large, then data mining...
