Enhancing Inspection Methodology of Solar Power Plants Through Integrated Infrared Thermography and 3d Data Fusion
No full textInfrared thermography (IRT) is a non-invasive imaging technique that enables qualitative and quantitative temperature analysis. In some thermographic applications, geometry and spatial relationships are crucial for analyzing surfaces and localizing thermal defects. These include photovoltaic (PV) power generation systems, a rapidly expanding sector in response to the growing demand for renewable energy that requires fast and accurate monitoring technologies for maintenance operations. This research aims to develop a technology to monitor the operation of solar modules and possible anomalies by simultaneously acquiring aerial images by connecting optical and thermal infrared sensors to unmanned aerial vehicles (UAVs), obtaining thermal orthoimages as output. Results indicate significant improvements in accuracy and reproducibility, making this methodological approach a promising option for rapid monitoring compared to other current alternatives, making consumer-grade thermal imaging cameras accessible for thermal orthoimage generation
Scan-To-Bim Procedure for an Old Industrial Plant
No full textThe work presents an efficient solution, based on integrating different data sources, for the digitization and modelling of an old structure with the HBIM methodology. It deals with survey issues, focusing on the various design approaches between parametric and not-parametric architectural elements. A procedural pipeline is formalized for data acquisition, processing, and generating a complete model for a disused industrial plant, formerly used for tobacco processing and located in the city of Battipaglia, Italy. The most difficult challenge is to obtain parametric objects of complex geometries. The results obtained corroborate with the robustness and accuracy of the proposed strategy
AR to Rediscover Heritage: the Case Study of Salerno Defense System
No full textRecognizing and transmitting the uniqueness and identity of one’s territory represents fundamental step to guarantee its sustainability, protection and valorisation. Of particular importance, moreover, is the issues of the lesser-known heritage of great value but which, unfortunately, in some cases is still little known and often in a state of neglect. However, the diffusion of new technology and the great development of digitization positively contribute to the accessibility and visibility of these patrimonies, increasing the knowledge and the dissemination. This contribution focuses on one of the towers of the coastal defence system, a perfect example of a lesser-known architecture of great interest to be valued. Through a multidisciplinary approach, which inextricably links history and new ICT applications, it will be possible to improve the knowledge of the heritage, enriching with complementary information that goes beyond the simple geometric definition of the building: an important tool for protection and preservation mainly for informative purposes
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
Image-based georeferenced urban context reconstruction in a BIM environment: the case of the Crotone Fortress
No full textThe potentialities of the use of the UAV survey as base for the generation of the context mesh are illustrated through the experiments on the case study, the Crotone Fortress, proposing two workflows for the importation of the triangulated model, maintaining its real geographical coordinates, in the Autodesk Revit environment through a Dynamo Visual Programming Script [VPL]. Starting from the georeferenced context of the photogrammetric mesh, nine federated BIM models were produced: four of the urban context, four of the detailed areas, and the architectural model of the fortress
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
