Pianificazione degli investimenti nelle reti idriche per il miglioramento dei livelli di servizio

Consequential life cycle assessment of the Italian power system
2022
Energy production and consumption contribute to 76% of the European greenhouse gas (GHG) emissions in 2018, and 90% of global GHG emissions with land use, land use change and forestation (LULUCF) in the same year. By applying energy efficiency (EE) and renewable energy (RE) technologies, the GHG emission intensity of the energy sector reduced by 1.3% in 2018 compared to the previous year. The current climate change policy aims at decarbonization, sustainable environment, economic prosperity and social equity. It requires the deep decarbonisation of the economies, meaning that the energy and power systems as well as other emission intensive sectors need to transform into zero-emission ones. …
The New Nino Capability Index for Dynamic Process Capability Analysis
2015
The process capability analysis is a crucial activity to evaluate if the process outcome meets the design specifications. Classically, such analysis is performed by verifying the in-control condition of the process and evaluating suitable capability indices, by assuming the process in-control steady-state condition. However, the in-control period of the process characterizes only a part of the system functioning cycle, the one with the lower defective rate. In particular, the system functioning cycle is also characterized by the out-of-control period, during which a greater defective rate is produced, and such increasing is not considered by the widely adopted capability indices. As consequ…
PROCESSO CONSERVATIVO E SIGNIFICATIVITà UN APPROCCIO METODOLOGICO PER LA PROGETTAZIONE DEI SISTEMI DI PROTEZIONE NEI SITI ARCHEOLOGICI/CONSERVATION P…
2018
Patrimonio culturale in generale e dei beni archeologici in particolare, in ragione della loro duplice natura (materiale e immateriale) e coerentemente con l’interesse della Cultura tecnologica per la centralità di quegli aspetti di processo che sono determinanti per una loro adeguata valorizzazione e ampia fruizione, il presente contributo propone un modello di valutazione per capire ‘cosa’ conservare e ‘per- ché’ nell’ottica di uno sviluppo sostenibile, ancor prima di ‘come’ farlo, consentendo una più chiara lettura e una più agevole interpretazione delle complesse relazioni esistenti fra le preesistenze archeologiche, il contesto naturale e i sistemi antropici aggiunti. Il modello di val…
A study on the assessment of the production costs curves in micro-grids
2013
In micro-grids, due to their small scale, there is commonly only one power supplier. A competitive wholesale market hardly exists, so the question about how to consider market issues for small producers within micro-grids arises. On the other hand, the specific features of micro-grids where load and generated power hardly find a balance, require that customers take part to regulation issues, also using demand-response (DR) programs. In this paper, price responsive (PR) policies and their programs are discussed to answer this question. A case study of a micro-grid with one micro-turbine and two photovoltaic (PV) generators is analyzed to assess the overall production cost in order to build a…

Una rete costiera tra dentità e degrado
2009
Il volume affronta le problematiche relative al governo dei territori costieri, in particolare meridionali, a partire dalle sollecitazioni emerse in occasione del VII Congresso Regionale dell'INU Sicilia Territori costieri: quali politiche per un governo integrato, organizzato a Palermo il 29 e 30 novembre 2007. Gli ambiti costieri di riferimento, fortemente urbanizzati e spesso oggetto di uno sviluppo non regolamentato, sono espressione di una complessità che generalmente viene affrontata con pratiche e strumenti pianificatori di settore, talvolta anche contraddittori, che ne mettono a repentaglio il fragile equilibrio. Il volume si compone di quattro parti l'identità dei territori; le pre…
Developing Tele-Operated Laboratories for Manufacturing Engineering Education
2010
The aim of the PeTEX-project is to establish an e-Learning platform for the development, implementation, and delivery of educational training programs in the field of manufacturing engineering. The PeTEX team designs both: a technical platform for eLearning based on “Moodle” including distributed tele-operated experimentation facilities, and didactic and socio-technical requirements for a successful online learning community. User interfaces are deployed for remote access to instruments, data analysis and multiplexed data access via network protocols. Hence, the platform provides complex tools in order to perform various activities to support the educational process, from telemetric experim…
Electrical Safety Analysis in the Presence of Resonant Grounding Neutral
2019
The resonant grounding is one of the possible methods of the system neutral grounding for the medium voltage distribution. IEEE standards do define this grounding configuration, but important advantages and drawbacks of the resonant grounding might not be fully known, due to its rather uncommon application in North America. On the other hand, resonant grounding in Europe is imposed by the increased requirements for power quality, especially for medium-voltage (MV) industrial users, imposed to electric utilities by regulatory authorities, with the purpose to protect the interests of users and consumers. Level of the continuity of the service, magnitude and phase of ground-fault currents, mag…
