PoliSave: Efficient Power Management of Campus PCs
Full text linkIn this paper we study the power consumption of networked devices in a large Campus network, focusing mainly on PC usage. We first define a methodology to monitor host power state, which we then apply to our Campus network. Results show that typically people refrain from turning off their PC during non-working hours so that more than 1500 PCs are always powered on, causing a large energy waste. We then design PoliSave, a simple web-based architecture which allows users to schedule power state of their PCs, avoiding the frustration of wasting long power-down and bootstrap times of today PCs. By exploiting already available technologies like Wake-On-Lan, Hibernation and Web services, PoliSave reduces the average PC uptime from 15.9h to 9.7h during working days, generating an energy saving of 0.6kW/h per PC per day, or a saving of more than 250,000 Euros per year considering our Campus Universit
Distributed algorithms for green IP networks2012 Proceedings IEEE INFOCOM Workshops
Full text linkWe propose a novel distributed approach to exploit sleep mode capabilities of links in an Internet Service Provider network. Differently from other works, neither a central controller, nor the knowledge of the current traffic matrix is assumed, favoring a major step towards making sleep mode enabled networks practical in the current Internet architecture. Our algorithms are able to automatically adapt the state of network links to the actual traffic in the network. Moreover, the required input parameters are intuitive and easy to set. Extensive simulations that consider a real network and traffic demand prove that our algorithms are able to follow the daily variation of traffic, reducing energy consumption up to 70% during off peak time, with little overheads and while guaranteeing Quality of Service constraint

Osservazioni penalistiche 'a prima lettura' sul progetto di codice della crisi e del'insolvenza
Full text linkIl presente contributo raccoglie alcune riflessioni sulle implicazioni penalistiche e processual-penalistiche del recente schema di decreto legislativo attuativo della l. 19 ottobre 2017 n. 155, recante una delega per la riforma delle discipline delle crisi d’impresa e dell’insolvenza. In particolare, sono prese in considerazione sia le (non numerose) disposizioni direttamente incidenti sulla materia penale, sia alcuni fra i possibili effetti espansivi o riduttivi della responsabilità penale scaturenti dal nuovo assetto del diritto concorsuale dell’insolvenza
