A multi-disciplinary approach to the preservation of Cultural Heritage: a case study on the Piazzetta degli Ariani, Ravenna
No full textThe Interdepartmental Centre for Industrial Research (CIRI) – Building and Construction of the University of Bologna is a ‘cross-over’ research board composed of several departments whose scholars come from different disciplines. their aim is to work together, share their know-hows, and dibate issues from different points of view.
The pilot project concerns the ‘Square of the Arians’, Ravenna, Italy, suffering from chronic problems of physical and social deterioration, despite the fact that the Arian Baptistery is part of the Unesco World Heritage List. Moving from an analytical historical study of the site and of its sources, a large-scale operational project led to the reconstruction of different diachronic phases of the site through 15 centuries of history and has produced a 3D reconstruction and Virtual Tours for remote and mobile visualization. The results were displayed in July, 2013 by a conference and an open, multimedia exhibition in the Square itself, comprising 3D modelling, videos, interned-based support utilities, etc. Such a project represents a successful and flexible result to be adapted to different cases in the field of the preservation of the Cultural Heritage
Photographing the past: using cloud computing and photo-modelling for 3D historical architecture modelling
No full textHistorical architecture often features very detailed elements that are frequently characterized by complex ornamentation, such as capitals, vaulted arches, portals, mouldings etc. Modelling such highly detailed surfaces with traditional software packages can be a very difficult and time-consuming task.
This poster discusses the combined use of two software applications to integrate traditional three-dimensional reconstructions of historical architecture and 3D models generated by semi-automatic photo-modelling.
Two famous churches in Ravenna were used for the case studies: San Giovanni Evangelista and Spirito Santo.
These churches are two outstanding examples of early Christian architecture in Ravenna; built between the 5th and the 6th centuries, they feature excellent examples of the key elements of religious architecture of late antiquity and the medieval period.
The aim of the study was to document the modifications made to these churches through the centuries by means of a three-dimensional reconstruction that was chiefly created with the combined use of two open-source software programs: Blender was used to recreate the main structures such as walls, apses, roofs and windows, and Autodesk 123D Catch® was chosen to generate 3D textured models of the most detailed parts: capitals, portals, decorated columns and the ambo of Spirito Santo. The success of this technique demonstrates that the use of a hybrid workflow can simplify the generation of complex shapes, increase the level of detail, and speed up the whole modelling process
Le origini ravennati degli archetti pensili
No full textThis essay was prepared by an interdisciplinary research team that combines exper-
tise in architectural history with the most up-to-date digital survey methods. The
system of “pievi” at the center of interest (S. Pietro in Sylvis, S. Pancrazio in Russi,
S. Maria in Ronta, S. Pietro in Trento, S. Giovanni in Ottavo) is located in the ter-
ritories of Romania, heir to the Byzantine Exarchate, included in the archdiocese
of Ravenna. The group of churches is usually attributed to the 9th-10th centuries and
presents a phenomenon of considerable interest: the arched corbel table decora-
tion. The research involves a very precise survey of all preserved structures in the
area and comparative investigations capable of reconstructing the historical devel-
opment of these building

Il punto sulle decorazioni di Palazzo dei Diamanti negli anni di Cesare d’Este. Nuove riflessioni e un progetto di tour virtuale.
No full textThe current state of the art of the decorations of Palazzo dei Diamanti in the years of Cesare d’Este.
New reflections and a virtual tour · The painted cycle in the apartment of Cesare d’Este in Palazzo dei Diamanti
has been the most remarkable interior decoration in late 16th century Ferrara. Our essays aim at
reconsidering the enterprise from different points of view, studying the original disposition of canvases
on the wooden ceilings and wall friezes, and the iconographical choices of the patron. Resting upon archival
documentation and sources, with the collaboration of the MultiLab in the Department of Cultural
Heritage, University of Bologna, we propose the reconstruction of the decoration through virtual realit
Cloud computing e fotomodellazione come integrazione della modellazione 3D per l’architettura storica. La chiesa di San Giovanni Evangelista in Ravenna
Full text linkHistorical architecture often features very detailed elements that are frequently characterized by complex ornamentation, such as capitals, vaulted arches, portals, mouldings etc. Modeling such highly detailed surfaces with traditional software packages can be a very difficult and time-consuming task, which often requires considerable skills and does not always ensure a strict adherence to the original object. This article discusses the combined use of two software applications to integrate traditional three-dimensional reconstructions of historical architecture and 3D models generated by semi-automatic photo-modeling. The case study is represented by a virtual reconstruction of the main structural changes undergone by the church of San Giovanni Evangelista in Ravenna, built by the Empress Galla Placidia in the 5th century AD. The aim of the study was to document the modifications made to this church over the centuries by means of a three-dimensional reconstruction that was chiefly created with the combined use of two open source software programs. Blender was used to recreate the main structures such as walls, apses, roofs and windows, and Autodesk 123D Catch was chosen to generate 3D textured models of the most detailed parts: capitals, portals, decorated columns.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
