Restauro e applicazioni informatiche. La gestione digitale della commessa per la documentazione e il miglioramento della qualità degli interventi di conservazione delle superfici architettoniche
No full textThe research project develops procedures and digital processes in order to enhance the design and the execution quality of interventions for the conservation of architectural surfaces. The aim is to finally promote the dialogue among disciplines with different natures but which are actually very close. The proposal consists in a mobile software based on the platform FileMaker for the management of restoration operations through the creation of a database organised in modules, permitting to register the analytic documentation of the entire restoration process. Moreover, the software allows to involve directly and at the same time the designer, the works supervisor, the construction company and the offices appointed for the preservation of historical buildings. These figures are called to participate directly and simultaneously in the decision procedure, in order to reduce the lenght of control and realization process in favor of a better cultural and technical quality, thanks to the implementation of “good practices” studied and developed with specific computer systems
Nonlinear analysis of masonry structures reinforced with the CAM system
No full textThis work focuses on the numerical analysis of masonry elements reinforced with the CAM system. An efficient macromechanical finite element modeling approach is proposed to reproduce the nonlinear response of such structures, based on a plastic-damage material model. Three main factors are investigated: setting of the steel stripes pre-tensioning values, definition of the boundary conditions, and calibration of the stripes post-yielding behavior. Hence, sensitivity analyses on pretensioning stress are carried out to investigate the effectiveness of the CAM system and provide designers with some useful recommendation
CTD profiles from oceanographic expedition HH/14 with RV HELMER HANSSEN in the Fram Strait in 2014
No full textSeawater temperature and pressure profiles from station HH14/00 from expedition HH14 (2014) in the Fram Strait. CTD data during the HH14 cruise were measured at regular intervals using a Seabird 911 Plus CTD on the R/V Helmer Hanssen. These profiles were used to characterise the physical structure of the water column in the Fram Strait
CTD profiles at stations GeoB22333-2 and GeoB22365-3 from MARIA S. MERIAN cruise MSM66
No full textConductivity-Temperature-Depth (CTD) profiles obtained in the Baffin Bay at stations GeoB22333-2 and GeoB22365-3 during the MSM66 cruise (22nd of July 2017 – 28th of August 2017). The CTD on-board Maria S. Marian is a Sea-Bird Electronics Inc. SBE 911plus (Temperature sensor SBE 3plus and Conductivity sensor SBE 43). The CTD has a depth rating of 6800 m, measuring conductivity between 0 and 70 ms/cm, temperature between 0 and 35ºC, and pressure between 0 and 10000 psi. The CTD is equipped with an additional sensor for fluorescence (WETLabs ECO FLNTU(RT)D)
CTD profiles from oceanographic expedition IAOOS with RV JAN MAYEN in the Fram Strait in 2008
No full textSeawater temperature and pressure profiles from stations 1 to 8 from expedition IAOOS (2008) in the Fram Strait. CTD data during the IAOOS cruise were collected using a standard SeaBird 911 Plus conductivity-temperature-depth (CTD) profiler on the R/V Jan Mayen. These profiles were used to characterise the physical structure of the water column in the Fram Strait
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
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
