This paper presents a noise reduction technique for vibration signal analysis in rolling bearings, based on local geometric projection (LGP). LGP is a non
Building stakeholders need compelling metrics, tools, data, and case studies supporting major investments in sustainable building technologies. Proponents of
We measured the pulse response nonlinearity of two silicon photodiodes at 193 and 248 nm with different measurement conditions. We found large and different
The best-known vulnerability scoring standard, the Common Vulnerability Scoring System (CVSS), is designed to quantify the severity of security-related software
Perfluorosulfonate ionomers (PFSIs) are of great importance in polymer electrolyte membrane fuel cell (PEMFC) applications. In order to optimize membrane
We examine a broadband method to extract the relative permittivity and loss tangent of low-loss dielectric substrates from on-wafer scattering-parameter
We present a technique for characterizing and modeling random vector-network-analyzer measurement errors. These errors manifest themselves as random changes or

The SIM time and frequency metrology working group has developed a comparison network for the Americas, with the goals of improving metrology in the SIM region
A method is presented for achieving high entrapment efficiencies of a hydrophilic drug simulant, sulforhodamine B (SRB), in nanometer-scale liposomes using a
The national standard for air kerma from gamma-ray beams is maintained in the US by the National Institute of Standards and Technology (NIST), the primary

In the ballistics measurements and correlations, optimum selection of c has particular importance for an unambiguous extraction of Individual Characteristics
This paper describes a platform for studying the bending behavior of ultra-compliant (stiffness less than 1 N/m) atomic force microscope (AFM) cantilevers. The
Error-motions of rotating axes are one of many sources of imprecision in machining. Accurate determination of axis of rotation error motions of the rotary axes
