This paper makes a distinction between measurement at surface and deeper levels. At the deep levels, the items measured are theoretical constructs or their
Knowledge and the way it is represented have a tremendous impact on the capabilities and performance of intelligent systems. There is evidence from studies of
The National Institute of Standards and Technology has created a set of reference test arenas for evaluating the performance of mobile autonomous robots

The degradation of concrete pavements is often controlled by the transport of a deleterious species (chloride or sulfate ions, or water in the case of freeze
In recent years, the use of fiber-reinforced vinyl ester and isophthalic polyester (isopolyester) composites in civil infrastructure has greatly increased, due
We discuss the multi-speaker tasks of detection, tracking, and segmentation of speakers as included in recent NIST Speaker Recognition Evaluations. We consider

We present the results of experiments and modeling of flip-chip geometry solder joint shapes under shear loading. Modeling, using Surface Evolver, included
Testing methods need to establish reliable performance data for laboratory water closet extraction tests with mixed media solid waste(s) standard materials are
We model a load using an artificial neural network (ANN) to improve an on-wafer line-reflect-match (LRM) calibration of a vector network analyzer. The ANN is
A detailed uncertainty analysis for NIST's pulse parameter measurement service is presented that represents the new pulse parameter measurement and extraction
