The safeguard of built heritage in archeological sites, an interdisciplinary approach based on light-weight UAV photogrammetry and terrestrial laser scanning survey: the case study of Monte Lucio
No full textThis paper introduces a well-defined working pipeline oriented to a multidisciplinary approach to analyze the structural behaviors of the Archeological Heritage through complementary and integrated studies. The geometrical and deterioration data pertaining to a medieval tower in “Monte Lucio” (Reggio Emilia, Italy) were joined in an accurate 3D model to be used for structural analysis, starting from the complementary use of a terrestrial laser scanning (TLS) with UAV air photogrammetry. Meanwhile, an interdisciplinary collaboration between different professional figures such as archeologists and chemists was established to get information relating to masonry stratigraphy and mortar typology. This allowed the material characterization fine-setting for parameters then embedded into structural models, usually the most complex operation in historical buildings. This led to classify the different brick typologies and the elevations’ characteristics in a 10x10 cm pixel matrix, identifying each slice uniquely by using different colors. The matrix was then imported in MATLAB, assigning coordinates and mechanical characteristics to each pixel, according to material typology. Finally, the model was imported in Abaqus Unified Fea to perform “Pushover analysis” and to calculate the distribution of horizontal forces to evaluate possible prevention measures to be taken. In conclusion, through the adoption of different combined digital survey technologies and multidisciplinary data sharing, the proposed workflow proved to
be efficient in the case study presented
Dati storico-archeologici dell’arsenale di Genova. Dal sottosuolo all’elevato
No full textBesides the extensive collection of documentary and iconographic sources, our knowledge of the port of Genoa can now count on the results of archaeological excavations. In 1988 investigations carried out during electricity works led to the identification of structures of the medieval mole, whose memory had been preserved only in a street name (‘Via del Molo’); this discovery has made it possible to locate the medieval military harbour in the area of Mandraccio. Presumably without installations to house the ships, it was abandoned in the early 14th C. because the basin had silted up; but already in the second half of the 13th C. the military harbour had been transferred west of the old mole (‘Spiaggia di Pré’), not far from the Hospital of the Hospitallers of Jerusalem, and was to remain there until the fall of the Republic of Genoa at the end of the 18th C. and the complete transformation into warehouses. Excavations carried out in 1992 on the occasion of the celebration of Columbus, re- vealed remains of the medieval arsenals, and made clear the arrangement of the basin in front, protected by a breakwater and divided into two sectors: the ‘darsena dell’arsenale’ and the ‘darsena del vino’. In 1982 in the same area, during work on the construction of a purification plant, seven pilasters of the medieval period were found, not aligned with the par- allel walls delimiting the slipways. Excavations in 2000-1 followed by a survey campaign in 2001-2, both carried out during work on the reclamation and restoration for the new Maritime Museum in the former Galata Quarter, were con- centrated on the structures of the ‘New Arsenal’ or ‘New Arches’, which in the early 17th C. were built to the east of, and adjoining, the Old Arsenal. The ‘New Arches’ complex originally consisted of eight slipways, intercommunicating through archways, and were destined in time to be reduced in number. The excavations have distinguished various lev- els of pavement, and identified in one sector a dry dock.
The archaeological analysis of the building elevation detected the original 17th century structure of the shipyard as it was described in ancient documents. The pillar and arch structure was completely hidden by later parts of the building and it was presumed completely lost. This structure was absorbed in the second half of the 18th century by a continu- ous one: stone and brick walls with barrel vaults in stone chips; giving rise to four levels of large galleries, more than 50 meters long with large stone vaults, 9 meters wide.
Archaeological investigation led to comprehension of the building transformations, using a rigorous survey of the structure and scientific analyses
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
Structural framework evolution from the 17th to 20th century in the Genoa Republic's Shipyard. Architectural archeology investigates the layers of structure
No full textVariations 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
