Piezoelectric model of rainfall energy harvester
2014
In this paper a model to predict the harvest of the energy contained in rainfall by means of piezoelectric transducers is presented. Different studies agree on the level of suitable generated voltage on the electrodes of a piezoelectric transducer subjected to rainfall, but a complete characterization on the supplied power is still missing. This work, in order to limit optimistic forecasts, compares the behavior of the transducers subjected to real and artificial rainfall, a condition that has shown promising behavior in laboratory.
A low-level spectrometer with a planar low-energy HPGe: shielding arrangement tests and system performance for 210Pb determination in air filter samp…
2001
A system for low-energy photon spectrometry using a planar germanium detector with appropriate specifications is presented. A spectrometric background investigation has been carried out with various detector shielding arrangements. The characteristics of the system for measurements of 210Pb in air-particulate matter on filters have been determined.
Selective harmonic mitigation with asymmetrical staircase voltage waveform for a three-phase five-level Cascaded H-Bridge Inverter
2020
Selective harmonics elimination or mitigation strategies are used in all applications where it is necessary to rise the efficiency and reliability of the overall system. This paper presents a simple approach to reduce the low order harmonics amplitude of an asymmetrical staircase voltage waveform for a five-level, three-phase Cascaded H-Bridge Inverter without solving non-linear equations. Through this simple approach, polynomial equations to evaluate the control angels in real-time operations have been found. The effectiveness of the harmonic mitigation method has been tested through the simulation analysis in MatLab/PLECS environment.

Investigation on the Single Event Burnout threshold behaviour of Power MOSFETs under atmospheric-like neutron spectrum irradiation
2017
N-channel power MOSFETs were tested at ChipIr (ISIS-RAL) with atmospheric-like neutron spectrum. Voltage thresholds for Single Event Burnout were evaluated and their correlations with the devices characteristics (V(BR)DSS) were investigated.

An accurate measurement procedure of power losses variations in electrical drives
2020
This paper presents a general procedure for the accurate measurement of power losses variations in electrical drives. More specifically, the paper addresses the issue related to the efficiency comparison of electrical drive controlled with different control algorithms. This procedure is applied to a permanent magnet synchronous motor drive, assessing its power losses by means of two different measurement systems, each one characterized by different accuracy and cost. The comparison between these two systems is carried out for different working conditions in terms of load, speed and magnetization in order to demonstrate that the power losses variations can be accurately measured even with no…

La disciplina della libertà personale
2019
I congegni della libertà personale del minore incrociano temi cruciali nella prospettiva sovranazionale dei best interests of the child: la tutela della personalità fragile del minore che ha fatto ingresso nel circuito penale attraverso la più traumatica delle vicende, quella della compressione della libertà individuale, ha imposto modalità di gestione individualizzanti improntate all’insegna della più ampia flessibilità, dal “primo contatto” ai paradigmi della discrezionalità giudiziale nella modulazione delle vicende cautelari. Spiccano, tra tutti, gli equilibri difficili tra educazione e cautela, nell’orbita di un sistema normativo imperfetto, che una prassi illuminata ha saputo declinar…
