An IPMSM torque/weight and torque/moment of inertia ratio optimization

2014

In this paper, a torque/weight and torque/moment of inertia ratio optimization procedure for interior permanent magnet syncronous motors (IPMSMs) is presented. More in detail, a performance comparison between several IPMSM rotor structures has been carried out in order to determine the optimum geometry that can maximize the torque/weight and torque/moment of inertia ratios. A commercial motor, with known electrical and mechanical characteristics, has been taken as reference. Its rotor structure has been modified several times, obtaining different rotor geometries and, therefore, many IPMSM models with different electrical and mechanical characteristics. The finite element method (FEM) analy…

Effect of pulse amplitude on depression and potentiation of ZrO2(Y)-based memristive synaptic device

2022

The effect of the amplitude of depressing and potentiating pulses on the synaptic plasticity (potentiation and depression) of a memristive device based on the Ta/ZrO2(Y)/Pt stack has been experimentally studied. It is shown that the amplitude of depressing and potentiating pulses affects the synaptic plasticity, namely, the value of current passing through the memristive device. The presented results demonstrate the prospects of using the ZrO2(Y)-based memristive devices as stable and low-power elements of neuromorphic systems.

LA ‘RESISTENZA’ DELLA SINISTRA POPOLARE DINANZI AL FASCISMO: IL DIALOGO CON I SOCIALISTI NELLE PAGINE DEL «DOMANI D’ITALIA» (1922-1924)

2022

On December 24 1922, in the midst of the tensions of the post- war crisis and the reactionary offensive, and just two months after the “March on Rome”, the left-wing of the Italian Popular Party published in Milan the weekly «Il Domani d’Italia» (December 1922-July 1924) taking the title of the Chris- tian Democrat weekly (1901-1903) edited by Romolo Murri. The deep religious, democratic and moral crisis pushed the editors – among others Francesco Luigi Ferrari, Gerolamo and Luigi Meda, Cesare and Luigi Degli Occhi – to a political commitment to the struggle and the related social culture. The condemnation of fascist authoritarianism, the need for an internal clarification of the PPI agains…
