Partial Discharges in HVDC Cables - The Effect of the Temperature Gradient During Load Transients
2021
The paper investigates the role of the space charge accumulation phenomena in the inception of Partial Discharges (PD) in a defect within the bulk of the dielectrics of a High Voltage Direct Current (HVDC) cable. It is widespread accepted that the number of PD occurring in an HVDC cable during its lifetime is largely less than that under AC voltage stress. This is essentially due to higher values of the voltage between the conductor and the screen needed to trigger PD under a steady DC voltage than the same value under AC stress. Nevertheless, due to the dependency of the electrical conductivity of the insulation on the electric field and temperature, PD in HVDC cables is strongly influence…
Development of bidirectional dc-dc converters for hybrid power sources - Final Report
2018
A Bidirectional Isolated Full-Bridge Converter was designed, prototyped and tested. The device is intended to interface a Bank of Supercapacitors with a battery-powered bus, in order to boost the capability of supplying large power peaks. The converter was based on the Isolated Dual Active Bridge configuration. When driven by an external control voltage, it is capable of generating in both directions a train of current pulses, with 2kW peak power, for any battery voltage in the range 24-32V and for any supercapacitor voltage in the range 35-70V. Worst-case battery current was 70A. Pulse duration was 100ms with 50% duty cycle and 1 ms rise time.
Potere disciplinare e norme incorporate
2020
The problem I discuss is whether the behaviors which are the product of the exercise of disciplinary power may be characterized as “normative”, and if so in what sense of the word “normative”. Disciplinary power is, I will say, the “inscription of norms” in the body of those who are subject to it. I distinguish two ways (“indirect” and “direct” inscription) in which norms may be inscribed, through the exercise of disciplinary power, in the body of the subjects, which I dub, respectively, “automatic execution (of norms)” and “normative automatisms”. Automatic execution of norms is a well-known phenomenon. Normative automatisms are odd entities: in the case of normative automatisms, the norm …
Vulnerabilità, concetto di diritto e approccio clinico-legale
2019
Does a clinical legal approach tell us something interesting about the nature and the concept of law? Is it possible to re-think the relationship between law and morals starting from the legal clinics experience? Is the juxtaposition between doctors and jurists convincing? These are the main questions that will be addressed here. They are questions concerning legal epistemology and legal philosophy in the strict sense that seems not to be so interesting for clinical jurists. Indeed, clinical jurists above all emphasize the importance of legal clinics from the viewpoint of education and social justice, but neglect the contribution that a clinical legal method can offer with respect to the kn…

La Direzione dei lavori
2009
Questa settima edizione del volume "La direzione dei lavori", successiva all'entrata in vigore del d.lgs. n. 81/2008 aulla sicurezza è aggiornata anche al terzo correttivo del Codice dei contratti.Il quadro normativo sui lavori pubblici è, in attesa del nuovo Regolamento sulle oepre pubbliche, costituito adesso dal d.lgs. n. 163/2006, dal Regolamento n. 554/1999, dal Capitolato generale d'appalto n. 145/2000 e dal Regolamento per la qualificazione delle imprese n. 34/2000. Nel volume sono inseriti oltre 140 modelli per la gestione degli atti relativi alla direzione dei lavori ed al collaudo e numerose tavole fuori testo contengono i diagrammi di flusso di alcune procedure.
La tutela civilistica del consumatore di fronte alle pratiche commerciali scorrette
2018
Lo scritto analizza gli strumenti civili di tutela, sia risarcitoria che invalidatoria, del consumatore, i quali appaionocomeun necessario complemento della disciplina pubblicistica volta a reprimere le pratiche commerciali scorrette. In particolare, l’esigenza di tutela della libertà del consumatore giustifica, a fronte di pratiche commerciali scorrette, una lettura non restrittiva delle norme in materia di responsabilità precontrattuale e di annullabilità del contratto per vizi del consenso o incapacità, in modo da garantire a questi rimedi un effettivo ambito di operatività.
