TIVOLI, HADRIAN'S VILLA: THE PLUTONIUM PROJECT (COMUNE DI TIVOLI, PROVINCIA DI ROMA, REGIONE LAZIO)
2021
The Universities of Pavia and Oxford continued their investigations in Villa Adriana, in the area called Plutonium, traditionally interpreted as a reproduction of the Underworld, and located on one of the highest rises of the complex, in the east part of the Villa. The excavations took place from 1 to 21 July 2019. A team of 12 graduate students and postdoctoral researchers took part in the project, both from Oxford and Pavia Universities (S. Andronio, I. Bossolino, E. Casarotti, A. Dalgkitsi, E. Di Virgilio, V. Jukic Buca, A. Poldi Allai, G. Restaino, T. Runeckles, A. Verde). Dr Gilberto Montali, from the University of Palermo, supervised the architectural survey and documentation of the a…
Il progetto Plutonium di Villa Adriana: prime considerazioni a margine del nuovo rilievo e prospettive di ricerca
2020
Nel corso del 2016 e 2017 la missione congiunta delle università di Oxford e Pavia ha condotto una serie di campagne di ricognizione, rilevamento (georadar e geomagnetico) e rilievo architettonico nell'area nota dalla letteratura archeologica come pertinente al Plutonium e Inferi di Villa Adriana. Il complesso, situato nella sona nord-orientale della Villa, in corrispondenza di un rilievo naturale e ai margini della proprietà demaniale è costituito da tre elementi principali: 1) una grotta artificiale/ninfeo, collocata all'estremità di una valletta artificiale, interamente scavata nel tufo (gli Inferi); 2) un grosso edificio costruito su alte sostruzioni concamerate (il Plutonium); 3) una r…
Tra antichità e medioevo: viaggiatori, architetti e intellettuali in Sicilia fra gli anni venti e trenta dell’Ottocento
2016
Quando Eugène Emmanuel Viollet-le-Duc raggiunge la Sicilia nell’aprile del 1836 è un giovanissimo professore dell’Ecole de dessin de Paris in procinto di compiere quello che per numerosissimi suoi precursori era diventato, ormai da diversi decenni, una tappa obbligata del Grand Tour in Italia. Frotte di rampolli dell’aristocrazia europea, ma soprattutto artisti e cultori di antichità avevano attraversato negli anni precedenti le strade talvolta perigliose dell’isola alla ricerca delle vestigia di mitiche città come Agrigento, Siracusa, Selinunte ecc., spesso tenendo insieme passione ar- cheologica e gusto del pittoresco, come può testimoniare il vastissimo repertorio iconogra co che abbiamo…
Impact of COVID-19 pandemic on mobility in ten countries and associated perceived risk for all transport modes.
2021
The restrictive measures implemented in response to the COVID-19 pandemic have triggered sudden massive changes to travel behaviors of people all around the world. This study examines the individual mobility patterns for all transport modes (walk, bicycle, motorcycle, car driven alone, car driven in company, bus, subway, tram, train, airplane) before and during the restrictions adopted in ten countries on six continents: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. This cross-country study also aims at understanding the predictors of protective behaviors related to the transport sector and COVID-19. Findings hinge upon an online survey con…
Discovering Homophily in Online Social Networks
2018
During the last ten years, Online Social Networks (OSNs) have increased their popularity by becoming part of the real life of users. Despite their tremendous widespread, OSNs have introduced several privacy issues as a consequence of the nature of the information involved in these services. Indeed, the huge amount of private information produced by users of current OSNs expose the users to a number of risks. The analysis of the users’ similarity in OSNs is attracting the attention of researchers because of its implications on privacy and social marketing. In particular, the homophily between users could be used to reveal important characteristics that users would like to keep hidden, hence …
Castellaccio of Monreale: From the Survey to the Visualisation of Virtual Reconstructions
2023
On Monte Caputo near Monreale stands a castle, presumably built in the twelfth century. The paper presents the first results of a still in progress survey activity, carried out on the entire monument using laser scanning and photogram-metric methods. This activity was carried out as part of a scientific agreement stipu-lated between the University of Palermo, Department of Architecture and the Club Alpino Siciliano, owner of the Castle. The graphic restitution of the survey provided new information and unpublished images of the castle. It was then possible to formu-late hypotheses on the virtual reconstruction of lost configurations. This was achiev-able thanks to the survey analytical read…
A virtual reconfiguration of two destroyed neighborhoods in the Old Town of Palermo
2018
The proposed contribution deals with the topic of virtual three-dimensional reconstructions on an urban scale. The choice was oriented on significant samples of city portions that over the centuries have undergone substantial transformations or distortions: the aim is to reconstruct their history backwards, starting from the current survey and using the tools of virtual representation to reconfigure the forms of the past and tell their events. From here comes the idea to create, for pieces, a hypertextual study of the urban image of Palermo: the theme of the transformation of the city, of change and of complexity, opens up differentiated research paths. The hypertext choice was almost obvio…
Disegnare il non costruito: la Caserma-Teatro G.I.L. di Luigi Moretti a Piacenza
2021
Come si misura la distanza che intercorre tra noi e un edificio rimasto sulla carta? Questa domanda apparentemente pretestuosa può esserci utile per incardinare delle riflessioni sull’uso del Disegno nello studio dell’architettura non realizzata, soprattutto quella del primo ‘900. Non a caso, nell’approfondire un progetto rimasto tale di Luigi Moretti per la città di Piacenza (la locale “Caserma-Teatro G.I.L.”) si è voluto prioritariamente verificare un metodo che prevede l’applicazione di alcuni degli strumenti propri della Scienza della Rappresentazione. I culmini di questo processo lento di decodifica e successiva esegesi sono stati certamente l’analisi grafica (che ha permesso di discre…
A discrete-element model for viscoelastic deformation and fracture of glacial ice
2015
a b s t r a c t A discrete-element model was developed to study the behavior of viscoelastic materials that are allowed to fracture. Applicable to many materials, the main objective of this analysis was to develop a model specifically for ice dynamics. A realistic model of glacial ice must include elasticity, brittle fracture and slow viscous deformations. Here the model is described in detail and tested with several benchmark simulations. The model was used to simulate various ice-specific applications with resulting flow rates that were compatible with Glen's law, and produced under fragmentation fragment-size distributions that agreed with the known analytical and experimental results.
Hybrid VLC/WiFi Architectures with Priority Feedback Channels
2022
In this paper, we consider integrating Visible Light Communication (VLC) and WiFi technologies in an ultra-dense (massive) Internet of Things scenario, where WiFi links are used for complementing VLC links and vice-versa. Indeed, in case of mobility and/or bidirectional communications, limited coverage areas and self-generated interference can be an issue. We consider hybrid VLC/WiFi nodes where the VLC link is used for the majority of (data) traffic and the WiFi link is employed as a feedback channel (e.g. transmitting TCP ACKs). In presence of intense WiFi traffic, the WiFi network may be congested and thus, to fully exploit the VLC bandwidth, we discuss possible priority mechanisms to fu…
