The authors introduce a new method for simulating phase-controlled induction motors. This method consists of utilizing the general model of the motor, referred to the equivalent two-phase machine, and of applying suitable input signals when the current is switched-off in one or more windings.

The measurement of the rotation speed is an important issue in closed-loop industrial drives. The motor speed is often calculated by a derivative operation of the position measure obtained by an electromagnetic resolver. As a consequence, especially at the lowest speeds, the noise overlapped to...

This paper outlines the results a multi-criteria evaluation study applied to the integrated assessment of flood protection options in Northern Italy. The study aims at comparing advantages and disadvantage of a more traditional approach based on hard infrastructure calibrated on the event with a...

This paper discusses the case for reforming the actual mechanism for charging water abstractions for hydropower production in Italy and proposes to introduce a performance-based environmental fee. This should be able, on the one hand, to internalize the environmental costs that hydropower...
