INQUINAMENTO INDOOR DA RADON. UNA APPLICAZIONE DELLE RETI BAYESIANE A SUPPORTO DELLA DIAGNOSI
Get PDFNel quadro più generale della tematica del controllo della qualità ambientale e più in particolare dell’Indoor Air Quality, la presente relazione riporta lo studio di un fenomeno di inquinamento da radon riguardante la scuola “G. Mancino” di Palermo.
Lo spunto viene offerto dal fatto che nel 2005, nel corso di un monitoraggio della radioattività ambientale di Palermo, i tecnici dell’ARPA Sicilia hanno rilevato in questa scuola elementare degli anni ’30, livelli di radon indoor molto superiori ai limiti di legge fissati dal D.Lgs. 241/2000.
Nella prima fase, dopo lo studio delle caratteristiche tipologiche e costruttive del plesso e l’acquisizione dei dati di misura pregressi, si è proceduto ad una nuova campagna di monitoraggio rivolta al rilievo di dati e misure sperimentali sulla presenza del radon indoor e dei dati meteoclimatici del contesto specifico.
Nella seconda fase è stata formulata una proposta di intervento sostenuta dall’analisi dei meccanismi di inquinamento attraverso modelli di simulazione.
In particolare l’approccio metodologico dello studio procede attraverso lo sviluppo di un modello di analisi basato sulle reti bayesiane, rilevatosi uno strumento utile di supporto per la diagnosi e le conseguenti decisioni progettuali, capace di controllare e descrivere fenomeni complessi e di stimare relazioni probabilistiche tra cause ed effetti
Accelerating human–computer interaction through convergent conditions for LLM explanation
No full textThe article addresses the accelerating human–machine interaction using the large language model (LLM). It goes beyond the traditional logical paradigms of explainable artificial intelligence (XAI) by considering poor-formalizable cognitive semantical interpretations of LLM. XAI is immersed in a hybrid space, where humans and machines have crucial distinctions during the digitisation of the interaction process. The author’s convergent methodology ensures the conditions for making XAI purposeful and sustainable. This methodology is based on the inverse problem-solving method, cognitive modeling, genetic algorithm, neural network, causal loop dynamics, and eigenform realization. It has been shown that decision-makers need to create unique structural conditions for information processes, using LLM to accelerate the convergence of collective problem solving. The implementations have been carried out during the collective strategic planning in situational centers. The study is helpful for the advancement of explainable LLM in many branches of economy, science and technology
The Meta Holonic Management Tree: review, steps, and roadmap to industrial Cybernetics 5.0
No full textIndustry 4.0 and 5.0 are currently pushing towards a reconciliation between humans and the concurrent evolution of cyber-physical systems of systems. This constitutes an increasingly complex battlefield in which management and engineering are experiencing hard times. The cybernetics framework, in its recent evolutions, should be refocused to recover a unifying edifice to these challenges. The Cybernetics 5.0, here proposed, aims at finding ways to deal with the complexity of control and management of pervasive networks of digital, analog, mechanic, and human-centered systems. These challenges had always been the basis of cybernetics, but they have been overshadowed by the impressive and exponentially fast advances in information and communication technologies, intelligent automation, and artificial intelligence. However, cybernetics is still crucial when engineering solutions need to move beyond the frontiers of the hard sciences for soft problems, and towards increased interdisciplinarity for hard problems. In this context, holonic architectures are seen as a valuable ground. Hence, holonic foundations are here perfected for the Cybernetics 5.0 vision. The Meta Holonic Management Tree is accordingly proposed as a first methodological instance and factual bridge between cybernetics and the complexities of Industry 4.0 and 5.0
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
