“…As a demonstration of GEMM’s capabilities for curvature measurement, profiles of that same mirror were measured with GEMM and the NIST Moore M-48 coordinate measuring machine. Although the methods are far different, two reconstructed profiles differ by 22 nm peak-to-valley, or 6 nm rms. …”

“…Therefore, the research aims to design a semi-automatic model for vulnerability analysis of threats for the National Institute of Standards and Technology (NIST) database of cyber-crime. We have developed a semi-automatic model that simulates the CVE (Common Vulnerabilities and Exposures) list of the NIST database between 1999 and 2021, concerning the resources used by the threat agents, pre-requisites input, attack vectors, and dormant results. …”

“…This paper describes the beginning and evolution of microwave rotational spectroscopic research starting in 1954 at the National Bureau of Standards (NBS), located at that time in Washington, DC, through the present at NIST in Gaithersburg, MD. David Lide was hired in 1954 to start this research employing Stark modulated waveguide septum cells. …”
