Electron energy loss spectroscopy in a transmission electron microscope (TEM) was used to measure elemental profiles of Si, 0 and N in the SiO x/Si xN y/SiO x...
A defected zone in the HVPE (hydride vapor phase epitaxy)-deposited GaN located near an interface with a SiC substrate was investigated by transmission electron...
This study seeks to elucidate structure-property relationships in a series of unfilled dental copolymers and their composites. The copolymers/composites were...
The gloss value of a test sample is determined relative to a standard, generally a polished piece of black glass. Therefore, gloss is a dimensionless quantity...
We demonstrate how a topological atom laser can be realized by output coupling a trapped vortex state with a Raman scattering process. We find a linearized...
Hexafluoro-1,3 butadiene (C,F,) is a potential new etching gas for the manufacturing ol semiconductors which has a very low global warming potential, unlike...
Experimental studies of the energetics and vibrational spectrum of the chloroperoxyl radical, ClOO, are contradictory. The most recent experiment accessed the...
The crystallization behavior of thin polypropylene films with and without 4-biphenyl carboxylic acid as a nucleating agent was investigated using high...
This article reviews the primary concepts of repository-centered development with the Unified Modeling Language, explaining the relation between notation...
This article compares Activity models of the Unified Modeling Language, version 2 (UML 2) [U2 Partners 2003], to a popular systems engineering (SE) flow diagram...
This is the second in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model...
Conceptual integrity is required for the result of data integration to be cohesive and sensible. Compromised conceptual integrity results in semantic faults...
A high-throughput combinatorial approach to the edge delamination test is proposed. This approach can construct the failure map as a function of temperature and...

We report on the design and performance of our second-generation 32-channel time-division multiplexer developed for the read-out of large-format arrays of...
This paper presents a master/slave cellular based mobile ad-hoc network architecture for multihop multimedia communications. The proposed network is based on a...

A FEA study of coating/substrate bilayers is conducted as a foundation for damage analysis. Attention is focused on the stresses along the contact axis...
This paper presents an experimental study of the angular response of an ellipsoidal radiometer performed using a 25 mm diameter variable temperature blackbody...
We use an atomistic tight-binding theory to study arrays of T-shaped GaAs/AlGaAs quantum wires. An atomistic approach allows us to provide a theory of the...
The spectrum of xenon excited in a low-inductance vacuum spark was photographed at high resolution in the region 9.5 nm - 15.5 nm. The observed transitions were...
As markets become unexpectedly turbulent with a shortened product life cycle and a power shift towards buyers, the need for methods to rapidly and cost...

The paper describes a model-driven method of systems integration using legacy models. The method defines relationships between elements of legacy models to...
A photometer/tristimulus colorimeter has been developed at the National Institute of Standards and TEchnology (NIST) to realize a color scale. A novel...
