2019
L'articolo riflette sul processo di istituzionalizzazione della Consulta delle Culture del Comune di Palermo, istituita nel 2013, ed analizza la campagna elettorare del 2018 a partire dalle interviste ad alcuni candidati e testimoni privilegiati. The article concerns the institutionalization process of the Council of Cultures of the Municipality of Palermo, established in 2013. Furthermore, it analyzes the 2018 electoral campaign starting from interviews with some candidates and privilege witnesses.
Terremoti e monumenti in Sicilia: la facciata campanile tra continuità, catastrofi e “ottimizzazioni” (XII-XVIII secolo)
2013
La facciata campanile è un archetipo dell’architettura religiosa siciliana. Dal Medioevo al Tardobarocco sono state costruite nell’Isola imponenti facciate torre con cella campanaria nell’ultimo ordine. Fino al XVI secolo questa tipologia, di matrice nord-europea, contemplava un avancorpo parallelepipedo addossato al prospetto, avente anche funzione di contrafforte a contenimento delle spinte impresse sulla facciata dalle arcate longitudinali interne, amplificate in caso di terremoto. La scarsa efficienza statica di queste prime strutture, verticalizzanti e monoblocco, è dimostrata dai crolli in occasione dei forti sismi che hanno colpito la Sicilia in età moderna. Nonostante le distruzioni…
Perizie sulla stabilità di cupole e campanili della Sicilia centro-orientale nel secondo Settecento
2015
Il saggio analizza episodi di criticità strutturali relativi a cupole e campanili della Sicilia del secondo Settecento (chiese Madri di Ragusa, Piazza Armerina e Caltagirone). In particolare verranno esaminati i progetti ex novo e le perizie redatti dall’architetto catanese Francesco Battaglia sulle problematiche relative al comportamento statico di strutture spingenti, come le cupole e le volte, o alte e isolate, come i campanili, di cui l’architetto propone soluzioni finalizzate alla loro fortificazione e sicurezza. Diverse relazioni tecniche, di cui alcune inedite, stilate da Battaglia nella seconda metà del XVIII secolo e talune in risposta ad altrettante perizie richieste a rinomati pr…
Arbitrary Phase Access for Stable Fiber Interferometers
2021
Well-controlled yet practical systems that give access to interference effects are critical for established and new functionalities in ultrafast signal processing, quantum photonics, optical coherence characterization, etc. Optical fiber systems constitute a central platform for such technologies. However, harnessing optical interference in a versatile and stable manner remains technologically costly and challenging. Here, degrees of freedom native to optical fibers, i.e., polarization and frequency, are used to demonstrate an easily deployable technique for the retrieval and stabilization of the relative phase in fiber interferometric systems. The scheme gives access (without intricate dev…
Measurements of Silicon Photomultipliers Responsivity in Continuous Wave Regime
2013
We report on the electrical and optical characterization, in continuous wave regime, of a novel class of silicon photomultipliers fabricated in standard planar technology on a silicon p-type substrate. Responsivity measurements, performed with an incident optical power down to tenths of picowatts, at different reverse bias voltages and on a broad (340–820 nm) spectrum, will be shown and discussed. The device temperature was monitored, allowing us to give a physical interpretation of the measurements. The obtained results demonstrate that such novel silicon photomultipliers are suitable as sensitive power meters for low photon fluxes.
Settlement, radiocarbon dates and craft productions during Late Neolithic and Bell Beaker periods in the ‘corredor de Montesa’ (Valencia, Spain). The…
2014
[EN] In this paper we present the results related to the excavation works conducted in Late Neolithic and Bell Beaker sites of Quintaret (Montesa, Valencia) and Corcot (l’Alcúdia de Crespins, Valencia), both in the middle valley of Canyoles river. The sites, neighboring each other, offer a quite different volume of information (Quintaret: 51 structures; Corcot: 4 structures). 14C dates allow us to define the occupation of this area of the valley along the first half of the III millennium cal BC. The presence of bell beaker ceramic in archaeological record of Quintaret is limited to just one structure (Q138), where at least 7 different vessels have been identified. Other prominent point of t…
Smart Assistance for Students and People Living in a Campus
2019
Being part of one of the fastest growing area in Artificial Intelligence (AI), virtual assistants are nowadays part of everyone's life being integrated in almost every smart device. Alexa, Siri, Google Assistant, and Cortana are just few examples of the most famous ones. Beyond these off-the-shelf solutions, different technologies which allow to create custom assistants are available. IBM Watson, for instance, is one of the most widely-adopted question-answering framework both because of its simplicity and accessibility through public APIs. In this work, we present a virtual assistant that exploits the Watson technology to support students and staff of a smart campus at the University of Pa…
Volver a la tierra. Transiciones agroecológicas de los sistemas agroalimentarios hacia la soberanía alimentaria
2016
La agroindustria prometía la erradicación del hambre en el mundo, pero a pesar del aumento de la producción agrícola cerca de mil millones de personas pasan hambre y por el otro lado más de mil millones padecen sobrepeso u obesidad, con enfermedades crónicas. El sistema agroalimentario es ineficiente e insostenible, provocando la pérdida de suelos, escasez de agua, disminución de la biodiversidad y conflictos sociales. Haciendo frente al modelo agroindustrial surge la agroecología como ciencia, que se alimenta de diferentes disciplinas y en principios de manejo observados en las prácticas campesinas tradicionales, con las cuales los pueblos han ido perfeccionando los agroecosistemas a lo la…
Global Spaces for Local Politics: An Exploratory Analysis of Facebook Ads in Spanish Election Campaigns
2021
[EN] Sponsored content on Facebook has become an indispensable tool for implementing political campaign strategies. However, in political communication research, this channel is still unexplored due to its advertising model in which only target audiences are exposed to sponsored content. The launching of the Facebook Ad Library in May 2018 can be considered a turning point in this regard, inasmuch as it now offers users direct access to ads paid for by political parties, among other advertisers. This paper analyzes some aspects of the strategies implemented by six national parties during the campaigns running up to the two general elections held in Spain in 2019, by performing an analysis o…
Representing social intelligence: An agent-based modeling application
2017
Abstract Intelligent systems are composed of autonomous components that interact each others, with and through the environment, in order to give intelligent support for reaching specific objectives. In such kind of systems the environment is an active part of the system itself and provides input for runtime changing and adaptation. Modeling and representing systems like this is a hard task. In this paper we propose a biologically inspired approach that combined with the use of Agent-Based Modeling allows to create a means for analyzing emergent needs of the system at runtime and converting them into useful intelligent services to be provided. The experiment proposed for validating and illus…
