Earth-centered inertial (ECI) coordinate frames have their origins at the center of mass of Earth and are fixed with respect to the stars. [1] " I" in "ECI" stands for inertial (i.e. "not accelerating "), in contrast to the "Earth-centered – Earth-fixed" ( ECEF ) frames, which remains fixed with respect to Earth's surface in its rotation ...

The model was first studied in 1976 and studies through the 1990s showed that adopting such a model could generate 10% savings on project time and 7% on cost. [6] The wider adoption of ECI was a recommendation of the 1994 Latham Report into systemic failings in the British construction industry; the practice became increasing popular during the early 2000s.
Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by François Arago in 1824, but French physicist Léon Foucault is credited with discovering them in 1855. ECT began largely as a result of the English scientist Michael Faraday's discovery of electromagnetic induction in ...
