Frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) was employed to measure over 100 transitions in the R-branch of the b1Σg+←X3Σg-(0,0) band for the rare O2 isotopologues. The use of 17O- and 18O-enriched mixtures allowed for line positions to be
A review of the evolution of modeling for accurate dimensional scanning electron microscopy is presented with an emphasis on developments in the Monte Carlo technique for SEM dimensional metrology. The progress of modeling for accurate metrology is

Sustainability has become a very significant research topic as it impacts many different manufacturing industries. Therefore, the technologies for monitoring, analyzing, evaluating, and optimizing the sustainability performance indicators for manufacturing
A Model-Based Enterprise (MBE) is an organization that applies modeling and simulation technologies to integrate and manage its technical and business processes related to production and product lifecycle support. By using product and process models to
This article introduces the Multi-Relationship Evaluation Design (MRED) framework whose objective is to take uncertain input data and automatically output comprehensive evaluation blueprints complete with targeted evaluation elements. MRED is unique in
A procedure is described for assigning values of the number of equivalent reference fluorophores (ERF) to microspheres labeled with a fluorophore designed to produce fluorescence in a given channel of a multicolor flow cytometer. There is a different

STEP-NC is the result of a ten-year international effort to replace the RS274D (ISO 6983) G and M code standard with a modern associative language. The new standard connects CAD design data to CAM process data so that smart applications can understand both
This paper presents infrared-based measurements and analysis of cutting tool temperatures for orthogonal machining of alloyed titanium. High-speed infrared video provided the basis for measurement of cutting tool temperature distribution as reported here

We describe a high sensitivity and high spectral resolution laser absorption spectrometer based upon the frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) technique. We used the Pound-Drever-Hall (PDH) method to lock the probe laser to the high
Nanowirenanocluster hybrid chemical sensors were realized by functionalizing gallium nitride (GaN) nanowires (NWs) with titanium dioxide (TiO2) nanoclusters for selectively sensing benzene and other related aromatic compounds. Hybrid sensor devices were
We report highly reproducible gravimetric and optical measurements of microdroplets enabled by fluidic pressure feedback control and state-of-the-art measurement systems that lend new insights into the process of drop-on-demand (DOD) printing. Baseline
By transferring of a small part of a macroscale sample to a novel thermally insulated sample platform we are able to mitigate flooding and electron heating problems typically associated with Environmental Scanning Electron Microscopy imaging of water

Temperature and plastic strain maps were obtained during orthogonal cutting of two AISI 4140 steels with different machinability indexes using a high-speed dual-spectrum (visible and infrared) and visible spectrum cameras, respectively. Surface and
This is an editorial article for a special issue on smart grid. The main objective is to report on some, if not all, of smart grid future technical challenges. While acknowledging its limited coverage, this issue offers a wide range of interesting
This article gives an example of improving the effectiveness of behavior modeling languages using ontological techniques. The techniques are applied to behaviors in the Unified Modeling Language (UML), using the logical meanings for classification
In our recent work, we have demonstrated effectiveness of the concept of multi-probe microassembly for manipulating and inserting microscale, sub-millimeter, parts to create three-dimensional microstructures. However, the approach has been based on trial
This paper describes an implementation of the IEEE 1451.0 and 1451.5 standards for smart transducers. The implementation, developed at the National Institute of Standards and Technology (NIST), uses Internet Protocol Version 6 (IPv6) over Low power
