Smart Machining Systems: Issues and Research Trends

November 1, 2005
Author(s)
Laurent Deshayes, Lawrence A. Welsch, Alkan Donmez, Robert W. Ivester, David E. Gilsinn, Richard L. Rhorer, Eric P. Whitenton, Florian Potra
Smart Machining Systems (SMS) are an important part of Life Cycle Engineer-ing (LCE) since its capabilities include: producing the first and every product correct; improving the response of the production system to changes in demand (just in time)

Summary of the Panel Discussion on Opportunities and Needs

November 1, 2005
Author(s)
Cedric J. Powell
At the NIST Workshop on Modeling Electron Transport for Applications in Electron and X-ray Analysis and Metrology, there was a final panel discussion on opportunities and needs in this area. A summary is given of points made by some of the contributors in

The Influence of Clay and Elastomer Concentration on the Morphology and Fracture Energy in Preformed Acrylic Rubber Dispersed Clay Filled Epoxy Nanocomposites

November 1, 2005
Author(s)
G Balakrishnan, P R. Start, D T. Raghavan, Steven Hudson, D Yebassa
The influence of toughener and clay concentration on the morphology and mechanical properties of three-phase, rubber-modified epoxy nanocomposites was studied. Nanocomposite samples were prepared by adding octadecyl ammonium ion exchanged clay to a

Theory of the Frequency Comb Output from a Femtosecond Fiber Laser

November 1, 2005
Author(s)
Nathan R. Newbury, Brian Washburn
The output of a femtosecond fiber laser will form a frequency comb that can be phase-locked through feedback to the cavity length and pump power. A perturbative theory is developed to describe this frequency comb output, in particular for a solitonic fiber

Thermochemistry of Inosine

November 1, 2005
Author(s)
J A. Boerio-Goates, Sarah D. Hopkins, Ricardo A. Monteiro, M D. Ribeiro da Silva, M A. Ribeiro da Silva, Robert N. Goldberg
The formation thermodynamic properties of crystalline and aqueous inosine have been determined by using a combination of calorimetric techniques. Oxygen bomb calorimetric measurements on crystalline inosine yielded a standard molar enthalpy of combustion

Correlation Charts for Ultraviolet-Visible Spectrophotometry

October 31, 2005
Author(s)
Thomas J. Bruno, Paris D. Svoronos
This section provides correlation charts and operational information for the design and interpretation of ultraviolet spectrophotometric (UV-Vis) measurements. While UV-Vis. is perhaps not as information-rich as infrared or nuclear magnetic resonance, it

Infrared Spectrophotometry

October 31, 2005
Author(s)
Thomas J. Bruno, Paris D. Svoronos
In this chapter, we present a series of correlation charts to aid in the interpretation of infrared spectra, and in performing infrared spectroscopic measurements. The correlation charts represent the characteristic absorptions that are produced by

Microfabricated Atomic Magnetometers

October 31, 2005
Author(s)
P Schwindt, John E. Kitching, Leo W. Hollberg, Svenja A. Knappe, V Shah, Li-Anne Liew, John Moreland
Using the techniques of microelectromechanical systems, we are developing chip-scale atomic sensors based on laser excitation of alkali atoms. Recently, we demonstrated a magnetometer physics package that had sensitivity of 50 pT / Hz1/2 at 10 Hz, had a

Nuclear Magnetic Resonance Spectroscopy

October 31, 2005
Author(s)
Thomas J. Bruno, Paris D. Svoronos
This section provides correlation charts and operational information for the design and interpretation of nuclear magnetic resonance (NMR) measurements.

Planning Report 05-2: IPv6 Economic Impact Assessment

October 31, 2005
Author(s)
Gregory C. Tassey
This report presents estimates of the costs and benefits associated with transitioning from Internet Protocol Version 4 (IPv4) to Internet Protocol Version 6 (IPv6). Cost estimates are based on likely development and deployment scenarios provided by
