Leveraging Blockchain and Smart Contracts for a New Frontier in Asset Management
No full textThis study explores the potential applications of blockchain technology
to enhance data authenticity and security in real-time monitoring systems. Considering the building or the structure (e.g., bridge, building frame), both systems can
be monitored via IoT. The collected data enable the construction of an information
model (digital shadow). Such conceptual models derived from the data can then be
certified via blockchain, on which smart contracts can be set up. From this approach,
two different strategic paths can be highlighted in the area of efficiency and security.
The first is related to the structural domain and concerns the identification of emergency situations through automatic algorithmic processing of the raw data collected
by sensors: if IoT identifies the exceeding of a safety threshold, for example, thus
associated with abnormal behavior or damage, this condition is mapped and certified
in real time. The smart contract set on the blockchain can at this point automatically
arrange for intervention on the emergency condition (operators warning, interventions, recovery actions, etc.). On the other hand, the certification of the raw data, in
parallel with the certification of the processed data, via blockchain allows for the
reconstruction of the emergency condition from the perspective of scenario but also
in terms of legal implications. The same blockchain and smart contract associative
process can be translated from the emergency scenario to the service scenario for the
management of routine maintenance contract
GIOVANNI CURIONI’S DIGITAL MUSEUM (2/2): POSSIBLE STRATEGIES FOR A DATA MANAGEMENT PLAN
Get PDFIn recent years, the Politecnico di Torino (Italy) is undertaking actions to promote and disseminate its historical archival and material heritage, both with onsite events and with digital tools and platforms dedicated to its digital museum. One of its most important collections is the Curioni’s one (1860-1887). It preserves reproductions of building structures used as teaching aids in the teaching of Construction Science. We are now working on the digitisation project of those artefacts, and we propose a study on the data management protocol structured to satisfy the FAIR principles (Findable, Accessible, Interoperable, Re-Usable). In fact, with the purpose of sharing and enhancing its materials, the Politecnico promotes the digitisation of its entire collection of Curioni’s models, to create a new section of its virtual museum. To this extent, one goal of our research is to foster the accessibility of this tangible heritage in the digital domain. In accordance with the Italian national digitisation plan, PND, we defined a Digital Management Plan for the cultural heritage products, DMP, to guarantee FAIR principles in sharing 3D digital artefacts of the Curioni’s collection. The DMP originated as public administration data management, but the result of this study demonstrates its usefulness also for digital cultural data management
GIOVANNI CURIONI'S DIGITAL MUSEUM (1/2): COMPARATIVE SURVEY TECHNIQUES FOR THE DEFINITION OF A 3D DATA COLLECTION PROCEDURE WITH LOW COST SYSTEMS
Get PDFThe potential of Virtual Heritage, with particular attention to the field of knowledge dissemination, not only in the educational and scientific field, of museum collections, which are very often not accessible, have long been at the centre of the digitisation policies of major national and international institutions. Within this framework, the proposed research is part of a broader research, involving scientific figures from different disciplinary fields for the definition of a workflow for the 3D acquisition, digitisation and creation of a virtual model of miniatures of architectural artefacts kept at the Polytechnic of Turin. The paper describes part of the experimentation conducted for the creation of 3D surveys carried out using different tools, such as a portable LIDAR, Mantis F6, a low cost LIDAR, iPhone 13 Pro, and a digital camera, Nikon Z5, evaluating their performance not only from a metric point of view, but also from a methodological point of view and the subsequent sharing of models in accessible digital environments. The conducted study therefore initiates a process of memory digitisation in order to create a digital platform in which to insert, in an organised and digitised manner, models, data, historical morphological information, material, documentary, etc., in order to make interaction with the virtual reconstructions possible, promoting a new accessibility, all this to test, standardise and define a possible working protocol for massive low-cost 3D artefacts acquisitio
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
