Realization of a Controllable Metafilm (''Smart Surface'') Composed of Resonant Magnetodielectric Particles: Measurements and Theory

November 1, 2005
Author(s)
Christopher L. Holloway, Pavel Kabos, Mohamed Mohamed, Edward Kuester, Michael D. Janezic, James R. Baker-Jarvis
In previous work, we derived generalized sheet-transition conditions (GSTCs) for the average electromagnetic fields across a metafilm, which, when properly designed, can have certain desired reflection and transmission properties. A metafilm is the two

Restructuring of Tungsten Thin Films Into Nanowires and Hollow Square Cross-Section Microducts

November 1, 2005
Author(s)
P. M. Parthangal, Richard E. Cavicchi, Christopher B. Montgomery, Shirley Turner, Michael R. Zachariah
We report on the growth of nanowires and unusual hollow microducts of tungsten by thermal treatment of tungsten films in a RF H2/Ar plasma at temperatures between 550-620 C. Nanowires with diameters of 10-30 nm and lengths between 50-300 nm were formed

Robust Optimization for Smart Machining System: An Enabler for Agile Manufacturing

November 1, 2005
Author(s)
Laurent Deshayes, Lawrence A. Welsch, Robert W. Ivester, M A. Donmez
This paper reports our efforts towards developing a mathematical and information framework for optimization of machining processes within a Smart Machining System (SMS). An SMS uses diverse integrated technologies that enable an enterprise to: (1) produce

Scanning electron microscope dimensional metrology using a model-based library

November 1, 2005
Author(s)
John S. Villarrubia, Andras Vladar, Michael T. Postek
The semiconductor electronics industry places significant demands upon secondary electron imaging to obtain dimensional measurements that are used for process control or failure analysis. Tolerances for measurement uncertainty and repeatability are smaller

Secure Messaging in BACnet

November 1, 2005
Author(s)
David G. Holmberg
A proposal for BACnet secure messaging is nearing public release by the BACnet standard committee (ASHRAE SSPC-135). The proposal adds a level of BACnet specific security to existing IT security, extending the BACnet standard to offer basic security using

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
