Strategies for the valorization of the small towns in the inland areas of Sicily
2019
La crisi degli insediamenti minori (specie nelle aree interne che presentano maggiore fragilità) impone che si debba ragionare su aree vaste per poter elaborare nuove visioni e costruire una nuova cittadinanza. La possibilità di operare sul territorio esteso diventa premessa di metodo e di operabilità del progetto, riconoscendo che i territori frammentati, le risorse puntuali (anche di grande valore storico e culturale) non sono più in grado di generare processi. The crisis of small settlements (especially in inland areas that are very fragile) requires a large-scale reasoning to be able to develop new visions and build a new citizenship. The possibility of operating on a wide territory bec…
Politiche e disposizioni per il ripopolamento dei piccoli centri abbandonati. Alcune riflessioni
2020
The contribution constitutes an introduction to one of the sections of the conference, which highlights the need to put in place, on the issues in question - the depopulation of inland areas - a pre-eminent pedagogical-formative action that helps communities to reverse their gaze by considering small towns a resource.
Small towns between Globalization and Sustainability
2011
I piccoli centri urbani rappresentano una frazione significativa della popolazione totale in molte regioni del mondo. Molti di questi centri hanno subito modifiche in seno alla loro economia e tipologia a causa della globalizzazione e dei cambiamenti economici del mondo avvenuti già nella metà del ventesimo secolo. L’economia locale indipendente delle piccole città, che è stata assorbita dall’economia globale, ha determinato la perdita delle identità locali e la loro stessa qualità di vita. In tale ragione risiede l’importanza di una progettazione urbana sostenibile - intesa come l’interazione tra economia, ambiente e benessere sociale – finalizzata a conservare i valori locali delle piccol…

Assessing the Economic Benefit due to BESS Management in a Renewable Energy Community of a Small Island
2022
The paper presents a study carried out on the island of Pantelleria regarding the interaction among distributed energy resource and energy storage systems in renewable energy communities. EU, in the Clean Energy Package, defines the 'Jointly acting renewables self-consumers' (JARSCs) and the 'Renewable Energy Communities' (RECs) as innovative models to share energy from renewables facilities. Nevertheless, the behaviour of JARSCs and RECs is designed to maximize the final users' self-consumption without considering the impacts on the power grid operation. A comparison of various operational strategies of BESS and an investigation of their effect on the distribution network are key elements …
Stability Analysis in a Vietnam Small Island for the Deployment of a Nearshore Wave Power Plant
2022
The requirement for a more sustainable energy mix is promoting the spreading of technologies supplied by renewable sources. However, the introduction of unprogrammable energy sources in small electrical grids could jeopardize the stability of the entire system. In this context, the paper analyses a small island in Vietnam, assessing the effects due to the installation of a new power plant supplied by sea wave energy. While the installation of this technology could represent a great opportunity to reduce the local energy dependence, on the other side the quality of the supply could be worsened. Solutions are assessed to allow a good network service.
An experimental analysis of power quality in presence of single phase grid connected photovoltaic systems
2004
In this paper, an experimental power quality analysis in presence of single phase grid connected PV systems is performed in a PV system installed at the Department of Electric Engineering of the University of Palermo through a measurement system set up by the Authors. In particular the analysis has been carried out focusing the attention on voltage and current distortion, as the solar radiation varies. The corresponding Total Harmonic Distortions in voltage and current terms are reported and compared with the standards limits. The presence of interharmonic components is also discussed.

Retinal image synthesis through the least action principle
2020
Eye fundus image analysis is a fundamental approach in medical diagnosis and follow-up ophthalmic diagnostics. Manual annotation by experts needs hard work, thus only a small set of annotated vessel structures is available. Examples such as DRIVE and STARE include small sets for training images of fundus image benchmarks. Moreover, there is no vessel structure annotation for a number of fundus image datasets. Synthetic images have been generated by using appropriate parameters for the modeling of vascular networks or by methods developing deep learning techniques and supported by performance hardware. Our methodology aims to produce high-resolution synthetic fundus images alternative to the…
