Get PDFThe last few years have marked an exponential growth in the use of electronic and computing technologies that opened new
possibilities and new scenarios in the Geomatic field. This evolution of tools and methods has led to new ways of approaching
survey. For what concerns architecture, the new tools for survey acquisition and 3D modelling allow the representation of an object
through a digital model, combining the visual potentials of images, normally used for documentation, with the precision of a metric
survey.
This research focuses on the application of these new technologies and methodologies on sensitive areas, such as portions of the
cities affected by earthquakes. In this field the survey is intended to provide a useful support for other structural analysis, in
conservation as well as for restoration studies.
However, survey in architecture is still a very complex operation both from a methodological and a practical point of view: it requires
a critical interpretation of the artefacts and a deep knowledge of the existing techniques and technologies, which often are very
different but need to be integrated within a single general framework.
This paper describes the first results of the survey conducted on the church of San Geminiano in San Felice sul Panaro (Modena).
Here, different tools and methods were used, in order to create a new system that integrates the most recent and cutting-edge
technologies in the Geomatic field. The methodologies used were laser scanning, UAV photogrammetry and topography for the
definition of the reference system. The present work will focus on the data acquisition and processing whit these techniques and their
integration
Integrated topographical and inclinometric procedures for long term monitoring of complex civil structures
No full textIn this paper, the complementary nature of topographical and continuous inclinometric monitoring procedures for the assessment of the movements of the complex structure being built is analysed.
The processes used in the two different monitoring systems and the results obtained are described. These are characterized by a significant homogeneity in terms of the precision of the two different types
of monitoring which can be considered interchangeable. It is therefore demonstrated that as the two systems are completely independent from each other and not correlated they can be used to validate each
other reciprocally
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
