Physical quantities are a characteristic or property of an object that can be measured or calculated from other measurements. Units are standards for expressing and comparing the measurement of physical quantities. All units can be expressed as combinations of four fundamental units. The four fundamenta...
In order to analyze the insertion task, we focus on force and moment information and inclination measurements. Conventional approach, i.e., a position-based analysis, is not appropriate for such a narrow dimensional tolerance because it is unlikely that human operators conduct the task based on ...
The aim of the paper is to suggest an approach to development of a theory of measurements for non-physical quantities. For these measurements it is not possible to ensure traceability because of their exclusive nature as substantiated by the author. This theory is presented as particularly importan...
The SI units together with the SI prefixes provide a logical and interconnected framework for measurements in science, industry, and commerce. In some cases, quantities are commonly expressed in terms of fundamental constants of nature, and use of these constants or “natural units” is acceptable...

Quantities covered include frequency, amplitude, and phase instabilities; spectral densities of frequency, amplitude, and phase fluctuations; and time-domain deviations of frequency fluctuations. In addition, recommendations are made for the reporting of measurements of frequency, amplitude, and phase ...
