2. Precision measurement equipment laboratory - Wikipedia

   en.wikipedia.org/wiki/Precision_Measurement...

   A Precision Measurement Equipment Laboratory (PMEL) is a United States Air Force (USAF) facility in which the calibration and repair of test equipment takes place. This practice is also known as metrology: the science of measurement. Metrology is defined as the science of weights & measures, while a PMEL is the place where technicians perform ...

3. Evaluation of binary classifiers - Wikipedia

   en.wikipedia.org/wiki/Evaluation_of_binary...

   The measure precision at k, for example, is a measure of precision looking only at the top ten (k=10) search results. More sophisticated metrics, such as discounted cumulative gain , take into account each individual ranking, and are more commonly used where this is important.

4. Calibration - Wikipedia

   en.wikipedia.org/wiki/Calibration

   The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...

6. Measurement system analysis - Wikipedia

   en.wikipedia.org/wiki/Measurement_system_analysis

   The ASTM has several procedures for evaluating measurement systems and test methods, including: ASTM E2782 - Standard Guide for Measurement System Analysis; ASTM D4356 - Standard Practice for Establishing Consistent Test Method Tolerances; ASTM E691 - Standard Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test ...

7. Accuracy and precision - Wikipedia

   en.wikipedia.org/wiki/Accuracy_and_precision

   The accuracy and precision of a measurement process is usually established by repeatedly measuring some traceable reference standard. Such standards are defined in the International System of Units (abbreviated SI from French: Système international d'unités ) and maintained by national standards organizations such as the National Institute of ...

8. Metrology - Wikipedia

   en.wikipedia.org/wiki/Metrology

   Metrology is a wide reaching field, but can be summarized through three basic activities: the definition of internationally accepted units of measurement, the realisation of these units of measurement in practice, and the application of chains of traceability (linking measurements to reference standards).

9. Dimensional metrology - Wikipedia

   en.wikipedia.org/wiki/Dimensional_metrology

   Standardized measurements are essential to technological advancement, and early measurement tools have been found dating back to the dawn of human civilization. [1] Early Mesopotamian and Egyptian metrologists created a set of measurement standards based on body parts known as anthropic units. These ancient systems of measurements utilized ...
