Acquisizione tridimensionale e fruizione digitale del busto loricato di Nerone. 3D modelling and digital exploration of the lorica bust of Nero
No full textLa digitalizzazione tridimensionale del torso loricato attribuito a Nerone è stata avviata con il duplice intento di valorizzare, da un lato, il patrimonio conservato presso il Museo Civico Archeologico di Bologna e, dall’altro, di sperimentare, in ambito scientifico, metodi e tecniche di rilievo digitale tridimensionale ad alta risoluzione, in grado di trasporre dati reali in ambiente digitale e consentire di condurre analisi da punti di vista e con finalità differenti.
Il modello tridimensionale ad altissima risoluzione del busto loricato di Nerone è stato manipolato nella sua restituzione grafica con la finalità di essere fruito sotto forma di proiezione olografica, trasformando, di fatto, la realtà fisica in una realtà aumentata
Documenting lost heritage. The experience of the survey of architectures damaged by the earthquake in the Emilia area, Italy.
No full textOne year ago, the earthquake that devastated a wide architectural heritage in the Emilia area, in Northern Italy, gave rise to a series of surveys and investigations aimed at both documenting a lost or seriously compromised heritage and at recording information that can be used by different operators (i.e. fire departments, civil protection, engineers, architects, urban planners) and for different uses in different times, concerning the development of safety, recovery, restoration or demolition programs.
The characteristics of that particular earthquake damaged a wide variety of buildings concerning both historical centers, rural buildings and recent buildings, that were built using different technologies. The devastation also involved buildings in which documentation on built heritage was collected, such as, for example, land registries and other historical archives. As a consequence, the impossibility to rapidly recover the previously acquired documentation or its unavailability gave rise to extensive survey campaigns.
Besides the urgency of developing safety programs, in some cases, these survey campaigns were also motivated by the purpose of collecting information on heritages that share common architectural composition and structural characteristics and therefore belong to specific building typologies. These kinds of investigations are particularly useful in case studies such as, for example, rural buildings, that were not previously accurately and documented in detail.
In other cases, large scale documentation was mandatory in order to conduct a census of specific heritages, such as, for example, worship buildings, and their location on the territory, in order to plan their reconstruction, demolition or restoration based on actual needs and real possibilities of intervention.
The aim of this contribution is to show how digital methodologies and technologies can be used as an indispensable practice in order to produce graphic documentation about an architectural heritage that has been destroyed or severely damaged by a natural disaster. The presented case studies belong to a repertoire that ranges from single buildings to wider complexes that were selected for their historical and cultural importance and for the urgency of the development of intervention plans.
In all case studies, the aim of surveys was to collect the most detailed and accurate information compatibly with the reduced possibility of access to unsafe buildings. In particular, most of them have been surveyed just from the outside, using fast and non contact survey methodologies, while documentation of inside spaces was collected through photographic repertoires, preexisting documentation or specific targeted investigations. In some cases, documentation was also integrated and completed thanks to accurate descriptions that were reported by people who lived those spaces.
All accessible areas were acquired mainly using laser scanners; in some cases, when accuracy and definition were not priority tasks, the indirect measurement approach supported by orthophotos was adopted instead of a range-based one.
In other cases, a structure from motion approach was used in order to quickly reconstruct the integrity of collapsed elements
SYNTHETIC BIOMIMETIC MINIMAL
No full text“Inspired by Nature” is an installation of the students’ work developed by two seminar classes at SCI-Arc (Southern California Institute of Architecture, Los Angeles) and one course at NABA (Nuova Accademia di Belle Arti, Milano). Each class, starting from a common quest, analyzed and developed a unique relationship with the natural world exploring design at different scales to provide a variety of interpretations and design proposals. The installation will be exhibited at NABA during the 2010 Fuori Salone (April 12-16) in Milan. The show will then travel to other locations during the following months.
Synthetic Visual Study Seminar at SCI-Arc (Instructor Elena Manferdini with the collaboration of Anna Maria Manferdini). The work of this seminar aims to extend the potential of architectural surfaces to produce effect through the invention of new breeds of artificial matter. Students investigated the ability of synthetic materiality to produce sensuality, tactility and visual novelty. Through the semester both analogical and digital procedures have been used as agents of design innovation. Modulation of texture, relief and colors derived by 3d scanned materials have been adopted as primary design source. Students used the textural qualities scanned from the animal and vegetal skins to develop new methodologies for highly articulated surfaces through the use of several experimental software technologies (Z-brush) and fabrication (CNC milling).
Biomimetic envelopes Applied Study Seminar at SCI-Arc (Instructor Ilaria Mazzoleni). The seminar finds inspiration from the animal world and, through the analysis and understanding of specific animal skin examples, translates the learned principles into the built environment. The ways in which the environment shapes the behavior and physiological evolution and adaptation of animals is an interesting question for many of us. How to translate the lessons learned from the analysis and observation of the animal world is the design learning experience proposed to students. The resulting architectural building envelopes perform and respond; they take into consideration various dynamic local environmental conditions and resources, enhancing and supporting them rather than exploiting them, creating a more sustainable way of building and living.
Minimal living Design Studio at NABA (Instructor Luca Poncellini). The aim of the course is to investigate the possibility of developing a complex task of interior and architectural design along a timeline, through the integration of dynamic schemes of organization, structures, and processes. Conceptual references for the project are derived from the observation of nature: natural phenomena, behaviors, strategies of organization and/or evolution, feedbacks loops. The analysis leads to the definition of an operational matrix of relations in space and time, adopted as a base for the project.
The tree different scales of design were chosen to support the pedagogical goals of “Design Is One”, a parallel on-going investigation that Elena Manferdini and Ilaria Mazzoleni have been conducting for the past three years. Focus of this research is the understanding of the disciplines of design and architecture within their historical and geographical context in Southern California and Northern Italy and the discovery of design fields through a series of site visits to world leading Italian and American designer studios that shaped the design field at large in the past century. This installation wants to promote the cultural exchange and the collaboration between the two institutions of NABA and SCI-Arc
Integrated multi-scalar approach for 3D Cultural Heritage acquisitions
No full textThis contribution presents the results of investigations on the reliability of technologies based on the Structure from Motion approach for the 3D digitization of build heritage. Since in the architectonical survey field the level of detail of acquisitions is based on scales of representation that range between values that are generally compatible with the definition provided by some of the most widespread SfM technologies, we tested their performances and developed a procedure with the purpose of easing the work of surveyors called to restore digital representations at different scales. Restored 3D models were compared among each other and with a gold standard acquisition. These analysis led to qualitative and quantitative evaluations and to considerations on times and skills required by all tested technologies. Strengths and weaknesses are here highlighted and the integration of different technologies is presented, as it generally represents the best solution in most multi-scalar contexts

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
