In this paper we explore how placing the same amount of absorber in different locations within a reverberation chamber can have different loading effects. This...
This paper provides the basis for an interactive mini tutorial and covers how to convert technical content to training materials. It includes: defining the...
The National Institute of Standards and Technology (NIST) now offers a service that provides customers with an oscillator locked to UTC(NIST), the United States...
The Sistema Interamericano de Metrologia (SIM), one of the world s five major regional metrology organizations (RMOs) recognized by the Bureau International des...
Refractometry of air is a central problem for interferometer-based dimensional measurements. Refractometry at the 10^{-9} level is only valid if air temperature...
The Moore M48 coordinate measuring machine (CMM) has provided NIST with unique and very flexible measurement capabilities for many years. The machines state of...
Linear modal analysis and superposition technique has been used extensively in earthquake engineering and seismic applications for decades, and it is here...
