Automation for product development and manufacturing is changing to take advantage of the recent expansion of the Internet and the computing technologies
This paper presents a mapping of a standardized representation of a function, consisting of schemata for functions and associated flows. Along with taxonomies
This paper presents an approach to support computer-aided conceptual design of mechatronic assemblies in a collaborative, multi-user environment. We describe a

In a distributed, object-oriented, hierarchical shop control system, there are many ways of organizing the interactions between supervisory controllers and
In this paper, we present the results of spectroscopic ellipsometry (SE) studies of Ta 20 5 films on Si. Based on these results, we have experimentally
We have developed a frequency-domain phase shift system for measuring the zero-dispersion wavelength of multimode optical fibers under overfilled launching

We have modifed a normal-incidence optical reflectance spectroscopy system to allow rapid switching between the measurement of sample reflectance and sample
The development of dense wavelength division multiplexed systems at wavelengths between 1300 and 1600 nm has created a demand for wavelength references
As part of an effort to characterize the uncertainties associated with temperature measurements in fire environments, models of bare bead, single-shielded
A new method has been developed to calibrate tristimulus colorimeters for high accuracy color measurements. Instead of traditional lamp standards, modern, high
This was an extended abstract prepared for inclusion in the Microscopy & Microanalysis '99 Proceedings. It is a summary of Observation of Antiparallel Magnetic
Based on concerns about indoor air quality and trends towards tighter envelope construction, there has been increasing interest in mechanical ventilation of
There is increasing interest worldwide in the use of performance standards for removing barriers to the acceptance of housing innovation.The use of performance
The degree of self-desiccation in field concrete depends on the availability of external water to replace that consumed due to the chemical shrinkage that

X-ray optical processes in solids--absorption, fluorescence and resonantscattering--are modeled within a band-structure-basedapproach to describe electron
We report measurements of heat transfer coefficients of flowing supercritical carbon dioxide (7.38 MPa critical pressure, 31.1 degrees C critical temperature)
Experimental data were collected for the purpose of validating multiphase combustion models and submodels. A spray combustor was fabricated that permits well
Active cavity radiometers (ACRs) have been used for years to measure solar radiation and Earth radiation from low Earth orbit. Extant space-flight ACRs were
Spiral inductors that are fabricated through a CMOS process, are micromachined by using a new post-processing procedure. In this new technique, the inductors
