Although instrumented indentation and atomic forcve microscope (AFM) are utilized extensively for the measurement of forces in the piconewton to millinewton
The step-diagonal test modifies the diagonal displacement test for machine tool performance evaluation by executing a diagonal as a sequence of single-axis

This paper investigates an alternative method to assess thermal errors due to the heat generated by moving linear axes using a spindle-mounted probe and simple
The National Bureau of Standards (now the National Institute of Standards and Technology (NIST)) pioneered the use of circular line-heat-sources in guarded hot
We discuss the performance of a feed-forward amplifier (FFA) at 10GHz. The feed-forward method is primarily used to suppress intermodulation distortion in

We demonstrate a simple technique to significantly improve the long-term frequency stability in atomic clocks vased on coherent population trapping (CPT). In
Developing exchange standards for technical product data started historically as multiple, and isolated, national efforts in the 1970s and early 80s. The
In this paper, we characterize microwave nonlinearity in a high temperature superconducting (HTS) thin film sample by measurement of a geometry-independent
Molecular dynamics simulation is used to calculate the infinite-dilution diffusivity of sodium hydroxide (NaOH) in steam at conditions of temperature and
