3D REALITY-BASED MODELING IN HBIM ENVIRONMENT APPLIED TO ARCHAEOLOGICAL SITES: RECONSTRUCTIVE HYPOTHESIS OF THE LATE-ROMAN FORT OF UMM AL-DABADIB (EGYPT)
No full textThe work aims to deepen the various aspects of three-dimensional modelling based on an image-based survey of an archaeological object. The architecture subject of this study is a
late Roman fortified structure, located in Egypt, in the oasis of Kharga, more precisely in Umm al-Dabadib. The aim was to model in a parametric environment the architectural evidence
measured both with classical approaches and with 3D surveys and to develop reconstructive hypotheses, assisted by historical and architectural documentation of archaeological sites
strictly interconnected to Umm al-Dabadib. If the model usually takes root from a project and develops gradually with it, in the historical and archaeological case the only starting point is
the current state of the building, narrated through surveys and documentation. Thanks to the close-range photogrammetric survey of the entire fort of Umm al-Dabadib, it was possible to
accurately reconstruct its shape and geometry and infer the construction techniques. This made it possible to recognize and understand the richness, peculiarity and uniqueness of each
modelled element, to identify and reconstruct its shape, to draw fairly reliable assumptions about its construction methods and therefore to reconstruct the entire architectural organism.
The irreversible destruction of elements of the building that established its identity is the main reason for recreating it even only in a virtual environment, through a virtual tool, albeit based
on the reality and tangibility of pre-existence. The strength of the reality-based modelling is that from the same digital survey it was possible
to develop different architectural solutions
Remote fruition of material and non material goods. ICT for IV century BC necropolis.
No full text— The technologies that allow the representation, the organization, the computation and the advanced exchange of information no longer reside within the exclusive domain of engineering. They are embedded in application products which suggest innovative themes and call for novel political, economic and entrepreneurial strategies and therefore more creative paths for research in general and Cultural Heritage in particular. Remote fruition of high interest sites is a central issue for historical, archaeological and environmental research whenever the themes and goods being studied are difficult to access for specialist researchers or no-technical user. One of such instances has been chosen to illustrate the potential of ITC via the description of a pre-organized information elaboration process, which is flexible as to demand
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
Digital immersive applications for a valorization project of a medieval stone village : a case study of Ghesc
Full text linkLAUREA MAGISTRALELa tesi presentata esplora le possibili applicazioni di tecnologie immersive di Realtà Aumentata e Realtà Virtuale nel campo della visualizzazione architettonica, considerando la loro capacità di valorizzare e re-immaginare i siti del patrimonio culturale. Il borgo medievale di Ghesc, caratterizzato dalla tradizionale architettura in pietra, è stato utilizzato come caso studio per sviluppare tre esperienze digitali con tre approcci tecnologici diversi: Immersal SDK, Unity VR e Spark AR. Queste esperienze sono state progettate non solo ai fini della conservazione digitale ma anche per essere di supporto alle attività di valorizzazione del patrimonio costruito dell'Associazione Canova come strumenti educativi, divulgativi e di marketing. Le tre idee progettuali di fruizione immersiva del villaggio in pietra ossolana, offrono nuovi approcci in cui gli edifici possono essere preservati e promossi, grazie ad approcci tecnologi innovativi e accattivanti. Infine, viene effettuato un confronto tra le tre ipotesi progettuali, analizzandone impieghi, accessibilità e bisogni. La tesi si conclude con considerazioni e valutazioni finali per programmare scelte future in base ai requisiti del progetto, ai limiti tecnologici, al contesto architettonico e ai criteri economici nella scelta degli strumenti digitali appropriati.This thesis explores the applications and uses of Augmented Reality (AR) and Virtual Reality (VR) technologies in the field of architectural visualisation, considering their ability to valorise and reimagine cultural heritage sites. The medieval village of Ghesc, characterised by its traditional stone architecture, was used as a case study to develop three digital experiences with three different technological approaches: Immersal SDK, Unity VR and Spark AR. These experiences were designed not only for digital preservation but also to support the Canova Association activities as educational, dissemination and marketing tools. These three digital project ideas for the immersive access to the Ossola stone offer new approaches in which buildings can be preserved and promoted, thanks to innovative and engaging technological approaches. Finally, a comparison of the three projects is made, analysing their uses, accessibility, and needs. The thesis concludes with final considerations and evaluations to plan future choices based on project requirements, technological limitations, architectural context and economic criteria when choosing the appropriate digital tools
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
The domes of the Amalfi Coast: survey and digital representation of complex shapes
No full textTo know the historic and cultural heritage it is especially interesting the group of domes, which characterize Salerno and the Amalfi Coast. This system displays several differences, which have to be researched if we want to achieve a deep knowledge of the architectonical heritage typical of this territorial context. From metric data acquired as 3D cloud points and filed as informative systems it also has been possible to develop geometric and formal researches to propose digital models of the analyzed domes. The presented research intends to act in two guiding principles: - to verify, in the field of digital representation and storage of architectural heritage, the capabilities of methodologies used for the RGB point clouds scanning; - to implement data and images scanned with an analysis and a visualization procedure, based on digital instruments in which the multiple levels of information space can explain the quantitative and qualitative relations beyond the objects themselves
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
