The behavior of fresh High- Performance Concretes (HPC) concrete is not substantially different from conventional concrete.

So, this is basic problem of one of most dynamic field of measurements technique, represented by electric measurements of non electric phenomena. The paper proposes a precision full-ware rectifier scheme that solves main aspects existing in conventional precision rectifiers based on diode and opamps.

It is known from many studies and investigations, that the drive vibrations are mainly responsible of the driver’ s performance perception and the vehicle’ s driveability.
