The lost memory of industrial places: the Ipanema blast furnace
No full textThis contribution is based on a joint research project developed by the University of Ferrara, Department of Architecture (Italy) and the Escola Politecnica USP of São Paulo (Brazil) by the which it was possible to scan the interior and exterior surfaces of the ancient blast furnaces of São João do Ipanema, an extraordinary example of industry of cast iron production of the XIX century.
The research was aimed at investigating the evolution of the blast furnace technique exploring a surprisingly rich Brazilian technical literature, with description records and drawings dated between the late 19th and early 20th centuries. Beside historical documentation it was also implemented on site a 3D survey campaign of the furnaces to understand how the profiles were modified along the time.
The first outputs of the project were thus focused on the evaluation of the transformation of the equipment in terms of more efficient shapes able to enhance the relationship between blast furnace profile fuel consumption and productivity.
The use of accurate digital technology, the following CAD elaboration of the chimney, the 3d model and the comparison with XIX century technical drawings confirmed that European directors of the plant were familiar with the most advance technical and scientific procedures and brought to the site a great technological improvement by an innovative know-how

Section I considers project goals and the attendant problems; Section 2 provides a brief summary of state-of-the-art experience and the technologies adopted by the Authors; Section 3 illustrates the key features of the 3-D color data acquisition methods used as well as the shape and color processing pipeline; Section 4 describes the specific study conducted on single elements and facades of the Coliseum in Rome, while Section 6 outlines future work
Integrated survey procedures: a methodological approach for documentation and representation applied to Emilia-Romagna theatres
No full textAfter the earthquake that struck the Emilia-Romagna Region in 2012, the need to activate efficient procedures for heritage conservation emerged. This paper presents a procedure for the integrated documentation of cultural heritage, starting from the current evaluation procedures, standards and tools for surveying seismic damage, namely the Form A (churches) and Form B (palaces) forms used by MiBAC (Ministry for Cultural Heritage). By adopting current tools, several information and details related to the historical, geo-morphological, stratified and structural data are lost. Starting from ongoing PhD research coordinated by the DIAPReM Centre of the University of Ferrara in collaboration with the Agenzia per la Ricostruzione dell'Emilia-Romagna-Sisma 2012, this contribution aims to deepen integrated survey procedures and management of digital tools. This contribution presents the overall methodological approach and a possible application on the Teatro Borgatti in Cento, Ferrara. Therefore, analysing the current scenario and State of the Art, a preliminary assessment of multilevel interpretation of damaged heritage will be illustrated as well as a possible management of seismic risk developing an interoperable and integrated BIM platform

Increasing resilience of Cultural Heritage Assets: the “BIMtoB Academy” project
No full textCultural Heritage is increasingly threatened with destruction not only by traumatic events, but also by rapidly changing social and economic scenarios, which consider the reuse of existing buildings in the same way as building preservation. Thanks to both the technological maturity and increased accessibility of ICT tools, the current digitalization of the building sector has brought about a way to increase the resilience capacity of cultural heritage. Moreover, the interoperability of systems and the new ways of sharing competences, among all the players involved, has lead to awareness of existing cultural heritage assets and risk factors related to transformation processes in the built environment. Consequently, it is possible to identify sustainable maintenance and enhancement strategies to make the preservation effective. The current “BIMtoB Academy” research project focuses on an impact assessment of BIM-based digitization in the construction sector for existing building project management. The study is based on
the application of Integrated Project Delivery Methods (IPD) in order to define, among the Universities, enterprises, real estate asset managers and Public Administrations involved, tailor-made information with different levels of detail and representation according to the type of intervention. Diagnostic analysis, safety, maintenance and an inclusive approach for the project are certainly emerging as key findings in order to drive more effective results
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

No full textThe research project described here concerns the high-definition 3D survey of the morphological and dimensional features of the collection of the marble bas-relieves carved at the beginning of the XVI century by the sculptor Antonio Lombardo to adorn the so-called “Camerino dei Marmi di Alfonso I” or “Camerino di
Alabastro” in the Estense Castle of Ferrara. The sculptures remained in their former place until the end of the XVI century and at present they are one of the masterpieces of the Hermitage Museum in Saint Petersburg. The research project started in March 2004 in occasion of the exhibition entitled “Il Camerino di alabastro: Antonio Lombardo e la scultura all’antica” and held in the Estense Castle of Ferrara. At the end of the exhibition, in June 2004, the bas-relieves returned to Saint Petersburg; the great artistic and historical importance of these bas-relieves and the limited time in which these artefacts were in Ferrara made the advanced 3D survey a useful methodology to build up a data base where to collect metric, morphological, geometrical and surface data. The 3D digital scanning in fact was integrated with further researches and instrumental diagnostic analyses aimed at the comprehension of the significant features and surface specifications of the marbles in order to create an integrated system of dimensional data and surface morphological aspects as a data system organized in the form of a 3D hyper-textual data base
Il rilievo come strumento di investigazione del processo di trasformazione: spazio urbano e luoghi della memoria
No full textNel più ampio ambito del rilievo della scena urbana e della documentazione digitale, che vede l’applicazione integrata di metodologie di rilievo tradizionale e avanzato, l’analisi del dato metrico-morfologico rilevato e la sua rappresentazione costituiscono un’interessante opportunità di ricerca sui processi di modificazione dello spazio urbano.
Il tema del rilievo e della rappresentazione degli spazi urbani è affrontato come atto conservativo e come strumento di tutela del patrimonio e della memoria. La tecnologia di rilievo laser scanner 3D, che permette indagini quantitative e qualitative, consente di organizzare i dati metrico-morfologici in database e di poter accedere, nel tempo, alla “memoria geometrica” di architetture e spazi urbani, come strumento di conoscenza, di ricerca, o come base per interventi di conservazione e restauro.
La ricerca incentrata sul rilievo degli spazi urbani e dei luoghi della memoria è frutto di diverse sperimentazioni di rilievo di contesti storici realizzate negli ultimi anni, e sfociata nella più recente esperienza di rilievo tridimensionale integrato dello spazio urbano pubblico del Largo della Memoria, nel centro della città di San Paolo, Brasile; il progetto è stato realizzato con la finalità principale di definire una metodologie per la documentazione dello spazio urbano in previsione degli interventi di restauro e conservazione
