INTEROPERABILITY MATTER: LEVELS OF DATA SHARING, STARTING FROM A 3D INFORMATION MODELLING
Nowadays, the adoption of BIM processes in the AEC (Architecture, Engineering and Construction) industry means to be oriented towards synergistic workflows, based on informative instruments capable of realizing the virtual model of the building. The target of this article is to speak about the interoperability matter, approaching the subject through a theoretical part and also a practice example, in order to show how these notions are applicable in real situations. In particular, the case study analysed belongs to the Cultural Heritage field, where it is possible to find some difficulties – both in the modelling and sharing phases – due to the complexity of shapes and elements. Focusing on the interoperability between different software, the questions are: What and how many kind of information can I share? Given that this process leads also to a standardization of the modelled parts, is there the possibility of an accuracy loss

From point cloud to BIM: a modelling challange in the Cultural Heritage field
Speaking about modelling the Cultural Heritage, nowadays it is no longer enough to build the mute model of a monument, but it has to contain plenty of information inside it, especially when we refer to existing construction. For this reason, the aim of the research is to insert an historical building inside a BIM process, proposing in this way a working method that can build a reality based model and preserve the unicity of the elements. The question is: "What is the more useful mean in term of survey data management, level of detail, information and time savings?" To test the potentialities and the limits of this process we employed the most used software in the international market, taking as example some composed elements, made by regular and complex, but also modular parts. Once a final model is obtained, it is necessary to provide a test phase on the interoperability between the used software modules, in order to give a general picture of the state of art and to contribute to further studies on this subject
BIM & Cultural Heritage: compatibility tests in an archaeological site (extended)
Nowadays, when people talk about BIM software, they refer to new constructions, made of regular elements and standard parameters. The question is: what happens when one, instead of a new building, considers an ancient or existing one? To answer this question, the possibility of using effectively the BIM process for the maintenance and the conservation of Cultural Heritage has to be evaluated. In particular, the research examines the case study of the archaeological site of the Sanctuary of Diana in Nemi (Rome), which is an important example in the National Heritage. The final product consists of a parametric model, where one can find, embedded in a database, all the information about the elements for the management of conservation projects. Highlighting positive aspects and existing limits, in order to contribute to further studies on the subject, leading to a mandatory implementation and use of this software, even in relation to future European legislative framework

INTEGRATION OF 3D MODELS AND DIAGNOSTIC ANALYSES THROUGH A CONSERVATION-ORIENTED INFORMATION SYSTEM
In the recent years, mature technologies for producing high quality virtual 3D replicas of Cultural Heritage (CH) artefacts has grown thanks to the progress of Information Technologies (IT) tools. These methods are an efficient way to present digital models that can be used with several scopes: heritage managing, support to conservation, virtual restoration, reconstruction and colouring, art cataloguing and visual communication. The work presented is an emblematic case of study oriented to the preventive conservation through monitoring activities, using different acquisition methods and instruments. It was developed inside a project founded by Lombardy Region, Italy, called “Smart Culture”, which was aimed to realise a platform that gave the users the possibility to easily access to the CH artefacts, using as an example a very famous statue. The final product is a 3D reality-based model that contains a lot of information inside it, and that can be consulted through a common web browser. In the end, it was possible to define the general strategies oriented to the maintenance and the valorisation of CH artefacts, which, in this specific case, must consider the integration of different techniques and competencies, to obtain a complete, accurate and continuative monitoring of the statue
Ospedale e territorio. I centri socio-sanitari.
Nel corso degli ultimi decenni l'invecchiamento della popolazione e la crescente esposizione a fattori di rischio ambientali e sociali hanno determinato in tutto il mondo un incremento delle malattie cronico-degenerative. La riconversione del sistema sanitario appare quindi una sfida irrinunciabile, come si evince anche da un recente documento stilato dall'associazione dei medici di famiglia britannici:"lo status quo non è più sostenibile. Se vogliamo soddisfare il bisogno di salute dei nostri pazienti negli anni a venire, dobbiamo produrre un cambiamento radicale nelle quantità, nell'organizzazione e nell'erogazione dei nostri servizi, a partire dall'assistenza primaria". Le nuove politiche assistenziali dovranno, quindi, seguire alcuni obiettivi fondamentali: integrazione tra ospedale e territorio, organizzazione multidimensionale dell'assistenza, presa in carico delle fragilità e della cronicità, prossimità e facilità di accesso ai servizi, empowerement dei pazienti nel processo di cura, monitoraggio dell'efficacia terapeutico-assistenziale. Inoltre, sarà necessario ridefinire l'approccio alle malattie croniche, passando da un metodo reattivo, basato sull'attesa dell'evento acuto, a un metodo pro attivo, improntato sulla prevenzione, per evitare o rinviare nel tempo il decorso della malattia
Un modello informativo parametrico per il Duomo di Milano. Test e Sperimentazioni.
Nowadays, with the spread of the BIM technology in the Cultural Heritage field, it is important to find, case by case, a method that permits to manage the archeological and architectural artifacts considering their personal needs.
In this case, the project focuses on a portion of the roofs of the Milan Cathedral, chosen for the complexity and richness in shapes of the components, which leads to difficult survey operations. The target was to experience complex methods of multi-sensor and multi-scale data acquisition and to build an infographic three-dimensional reality-based model in order to help and manage the conservation activities of the building. The complexity of the Cathedral’s late gothic style represents a hard challenge for the application of the innovative surveying methods and for modelling with a BIM-oriented software.
For this reason, the experiment was made with two different modelling methods (one is object-oriented modelling BIM and the other is based on the use of NURBS surfaces), in order to find the differences between the two, in terms of managing the survey data, modelling, the accuracy of the model, the time required to create it and the typology of data that they are able to visualize and insert.
The result of this work is an example of methodological approach that can enhance the widespread application of this innovative technology for restoration or maintenance activities of built heritage
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
