Ludus absentiae et praesentiae

2006

Volendo descrivere la soluzione di progetto come narrazione di scelte già realizzate sul corpo del Tempio-Duomo di Pozzuoli, come si guardasse a volo d'uccello, questa potrebbe essere descritta sinteticamente, come una architettura inclusa in un prisma di cristallo. Tale immagine riesce a rendere il senso complessivo di molti degli atti progettuali ipotizzati sul volume della chiesa ma, accanto a questi, vanno posti quelli che riconnettono in più punti il Tempio-Duomo al tessuto del rione Terra.

Imaginaire et réalité de l’évènement. Valencia et l’America’s Cup 2007

2009

Le sujet de cette proposition, qui fait état d'une recherche en cours sur la contribution des grands événements à la rénovation urbaine1, porte sur la relation entre infrastructures sportives et mécanismes de transformation des villes. L’analyse de la relation entre l’imaginaire et la représentation de l’événement permet d’aborder, d’une part, le thème de la reconnaissance internationale de l’image de la ville et, d’autre part, le thème de la détermination d’une stratégie urbaine de longue durée. C’est à partir de l’exemple de l’America’s Cup 2007 à Valencia, que sera interrogée la place de l’image et de la représentation des villes dites événementielles. Suivre quelques étapes qui ont cara…

Riqualificazione e valorizzazione piazza Cardinal Pacca, Bagni, Teatro Romano e calata Olivella

2006

La "riqualificazione" e valorizzazione delle aree di piazza Cardinal Pacca, Bagni, Teatro Romano e calata Olivella" si articola tra temi architettonici, urbani, paesaggistici e geografici di estremo interesse. Sulla individuazione di interventi circoscritti prevale, pero, una riflessione più ampia che si incentra su un tema che può essere da un solo termine: connessioni. Le connessioni urbane assumono a Benevento il carattere di necessità urgente. Infatti, la parte del centro storico interessata dal concorso di idee si presenta come un tessuto costituito da più strati. L'agire contemporaneo di edifici recenti ed antichissimi conferisce "senso" ed "identità" alla città. A partire da questa t…

Le front de mer de Valencia et l'héritage de l'America's Cup 2007

2009

The topic of this paper studies the relationship between temporalities and the transformative mechanisms in cities and neglected port zones. The central hypothesis posits that major events can be understood as tools of transformation of the contemporary city in which the event, by its very nature impermanent in character, can nevertheless have a permanent effect on the development of certain facilities. The permanency that gets established as a result of an short-term happening differs from traditional forms of urban intervention. Analysis of urban development growing out of a short-term event uses the case of the 2007 America’s Cup of Valencia to explicate a durable strategy between these …

Collegio, Benevento (pianta della prima sede del collegio presso S. Pietro de Trassedis)

2017

Scheda su un disegno relativo al primo sito ottenuto dala compagnia per la fondazione del collegio a Benevento. La scheda catalografica fa parte di un lavoro di revisione e aggiornamento del catalogo dei disegni di progetto delle sedi della Compagnia di Gesù, custoditi presso la Bibliothèque Nationale de France (BNF) e l'Archivum Romanum Societatis Iesu (ARSI), pubblicato da Vallery-Radot J. nel 1960.

Theoretical construct, method and working tool of the "preventive restoration". The electronic book for the prearranged maintenance of architectural …

2016

A restoration may constitute a positive moment to guarantee the conservation, transmission and a compatible use of an historical architecture, but it is often the result of a long and guilty omission of care, attesting a lack of interest in the architectural heritage we are late forced to heal with extensive and invasive interventions that, in most cases, could be prevented. Clear maintenance programs and a correct and well-planned preventive action could be sufficient to avoid unexpected interventions when it is too late; such simple concepts - apparently shared by everyone - however, remain relegated to a level of brainy attitudes or protocols that do not produce any advantage in terms of…

Urban Events as Cosmopolitan Accelerators and Post-Pandemic Cities: Reflections on Manifesta 12 in Palermo

2021

International events are important opportunities to generate (global) open spaces and networks, and are one of the greatest accelerators of cosmopolitan networks. The global Covid- 19 crisis asks us to rethink the mobility of people and the interconnections between and within cities, where networks and connections are the most powerful accelerators of what we may call the cosmopolitan dimension of urban life. How can we rethink Cosmopolitan Habitat in light of the pandemic? What kinds of international event will we be able to promote from an intra- and post-pandemic perspective? This contribution analyses the experiences of Manifesta 12 in Palermo. The event is explored as a field of experi…

An Active Learning Approach for Classifying Explosion Quakes

2022

In this work, an Active Learning approach for improving the classification of passed seismo-volcanic events is proposed. Here we study the specific case of Explosion Quakes from Stromboli Volcano versus other seismo-volcanic events, recorded as seismograms, and the use of Random Forest as a Classification method. In conformity with the active learning paradigm, the approach recalls the human intervention for the annotation of uncertain data. The uncertainty is established by the event probabilities, predicted by a trained random forest classifier. The human intervention consists of editing and relabelling the data into these main three classes: Explosion Quakes, Non-Explosion Quakes or Non-…

Transient behaviour of a “mixed” overhead-cable EHV line under lightning events

2009

Recently, in many countries have been undergone or are planning links with AC extra-high voltage (EHV) underground cables. Cable lines offer the possibility of a reduced environment impact and for this reason they are often the only alternative for the reinforcement or the expansion of power system accepted by public opinion. The coexistence of overhead and cable line in the so called ¿mixed¿ lines, however, raises several questions regarding their behaviour both in steady state and in transient. The purpose of this work is to investigate the transient behaviour of a mixed overhead-cable EHV line under lightning events, describing the effects of the following overvoltages on the system. The…

Rateless Codes Performance Analysis in Correlated Channel Model for GEO Free Space Optics Downlinks

2012

Settore ING-INF/03 - TelecomunicazioniFree Space Optics (FSO) technologies for satellite communications offer several advantages: wide bandwidth high rate capability immunity to electromagnetic interference and small equipment size. Thus they are suitable for inter-satellite links deep space communications and also for high data rate ground-to-satellite/satellite-to-ground communications. Nevertheless FSO links suffer impairments that cause power signal degradation at the receiver. Scattering and absorption cause power signal attenuations predictable by suitable deterministic models. Optical turbulence causes random irradiance fluctuations which can generate signal fading events and can thereby only be predicted by statistical models. Attenuation and fading events can corrupt FSO links and so it would be recommended to add mitigation error codes on the communication link. FSO channel can be described as an erasure channel: fading events can cause erasure errors. We have identified in rateless codes (RCs) a suitable solution to be employed in FSO links. RCs do not need feedback and they add a redundant coding on the source data that allows the receiver to recover the whole payload despite erasure errors. We implemented two different of rateless codes: Luby Transform (LT) and Raptor. We analyzed their performances on a simulated turbulent GEO FSO downlink (1 Gbps - OOK modulation) at a 106 μm wavelength and for different values of zenith angles. Assuming a plane-wave propagation and employing Hufnagel-Valley we modeled the downlink using: 1) a temporal correlated channel model based on Gamma-Gamma probability distribution and 2) an irradiance covariance function that we converted on a time function using Taylor frozen eddies hypothesis. Our new channel model is able to simulate irradiance fluctuations at different turbulence conditions as it will be shown in the full paper. We will also report performance results of LT and Raptor codes at overhead range varying between 0 and 50% and for different values of source packets.Settore ING-INF/01 - Elettronica
