In-process estimation of time-variant contingently correlated measurands

In-process estimation of time-variant contingently correlated measurands

This paper is devoted to the study and implementation of real-time techniques for the estimation of time-varying, contingently correlated quantities, and relevant uncertainty. An estimation algorithm based on a metrological customization of the Kalman filtering technique is presented, starting from...
