Rilievo laser del "Convicinio S. Antonio" al rione “Sassi” (Matera
No full textLa conoscenza, la manutenzione e la divulgazione di informazioni relative ad un notevole esempio di Bene Architettonico viene, in questo studio, esplorata con la metodologia della scansione Laser 3D e al contempo viene trattata in ambiente GIS tridimensionale. Il “Convicinio di S.Antonio” (XII-XIII secolo) è stato utilizzato come area-test. Si tratta di una Chiesa rupestre inserita nel più ampio sito storico dei “Sassi” di Matera, particolarmente interessante proprio per l’irregolarità di tutte le sue superfici e volumi scavati nella roccia viva. Il rilievo è stato realizzato con il Laser Scanner terrestre Leica HDS 3000, che permette con poche stazioni di ottenere un modello tridimensionale della Chiesetta molto preciso e particolareggiato, da cui è poi abbastanza facile estrarre anche le più tipiche rappresentazioni dell’oggetto architettonico, quali Piante, Prospetti e Sezioni, per poterle confrontare con quelle di un rilievo tradizionale preesistente. Viene poi esplorata la possibilità di un uso combinato di Cad e Gis in particolar modo con l’utilizzazione della “feature” Multipath, anche combinando insieme software di vario genere. La “feature” Multipath spesso trascurata dai software commerciali, si è qui rilevata di una certa utilità nel modellare un oggetto complesso, come quello esaminato, perché definisce completamente le singole parti delle superfici, e le rende più facilmente manipolabili anche con l’aggiunta delle informazioni semantiche derivabili dalle riprese fotografiche. La rappresentazione tridimensionale così ottenuta è poi stata utilizzata in ambiente Gis sia per i confronti con i rilievi storici, sia per verificare la possibilità di un trattamento veramente tridimensionale dell’oggetto rilevato con tipiche metodologie GisWith this study the Laser data acquisition and handling applied on a suggestive Italian Architectural Heritage was executed, in order to allow next complex spatial processing in 3D GIS visualization environments for the management and divulgation of information on Cultural Heritage. The site test is represented by the “Convicinio of S. Antonio” (XII-XIII centuries), that is one of the Churches carved into the rocks of the “Sassi”, the very ancient quarters of the Matera city. The Laser data of the above Churches were produced by means of the innovative technologies of the terrestrial Laser Scanner Leica HDS 3000, that it is able to extract in a fast way the third dimension of objects and makes high-definition field data capture easy and efficient. Particular attention was made on the potentiality of the CAD-GIS tandem using the feature type Multipatch with different softwares. The Multipatch permits to encapsulate complex objects in a compact way and to add also textures on surfaces, providing a real 3D objects visualization. Such technique is not still used because commercial GIS softwares have not specific tools to create 3D feature Multipatch. The 3D objects made with integrated procedures were next processed with GIS tools, verifying the effective possibility of executing three-dimensional thematic queries of complex georeferenced Laser data

No full textSince the Italian landscape is dense of historic centers and considering that the residential buildings
represent the main potential sector for reducing energy consumptions, the application of renewable energies
into these specific areas becomes an important issue. The use of such systems in these contexts is often
prevented by the lack of specific local legislative references. Therefore, this paper analyzes existing
regulations in order to provide background material for developing criteria useful to integrate renewable
energies into historic city centers. It has been developed in the framework of the IEA-SHC Task 51 Solar
Energy in Urban Planning (http:// task51.iea-shc.org)
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
