Titolo Tesi ( vecchio ordinamento):
Valutazione della pericolosità sismica locale per il centro abitato di Ponzano Superiore nel Comune di Santo Stefano Magra (Prov. di La Spezia).
Sintesi:
Il paese di Ponzano Superiore fa parte del comune di Santo Stefano Magra nella bassa Valle del fiume Magra sito in provincia di La Spezia.
L’obiettivo del presente lavoro è la valutazione della pericolosità sismica locale per il centro abitato di Ponzano Superiore, dove vengono individuate le condizioni geologico-geomorfologiche in grado di poter determinare, in occasione del verificarsi di un terremoto, amplificazioni degli effetti sismici connesse alle proprietà di sito ( es. riattivazione di corpi di frana, liquefazione, effetti cresta, ecc..).
La metodologia utilizzata per tale scopo segue in parte quella proposta dal VEL ( Valutazione Effetti Locali), utilizzata già dalla regione Toscana e adottata con le opportune modifiche anche dalla Provincia della Spezia.
Il presente studio è esteso all’individuazione di aree con possibili amplificazioni sismiche nel centro abitato, mediante la realizzazione di una carta di sintesi, ottenuta da cartografie di dettaglio ( alla scala 1:5000) di tipo geologico, geomorfologico, litotecnico.
La campagna di rilevamento, avvenuta nel periodo Gennaio 2005 – Giugno 2005 ha riguardato pertanto la raccolta di numerosi dati geologici, geomorfologici, litotecnici.
I dati geologici sono essenzialmente di tipo stratigrafico-strutturale, riguardanti la ricostruzione delle strutture del substrato,sintetizzata nelle sezioni geologiche, e la delimitazione e la caratterizzazione delle coperture.
Le varie forme e i processi che hanno portato all’assetto morfologico attuale delle aree studiate sono stati evidenziati nella carta geomorfologica.
In questa fase sono state rilevate le varie forme ( frane, detrito, alluvioni…) specificandone la genesi e lo stato di attività.
Durante il rilevamento sono stati acquisiti numerosi parametri litotecnici, utilizzati per la caratterizzazione degli ammassi rocciosi e delle coperture ( es. proprietà delle discontinuità, valutazione della resistenza alla comprensione uniassiale, raccolta di campioni rappresentativi per ogni formazione). I campioni di roccia raccolti in campagna sono stati successivamente analizzati in laboratorio ( Test di Point Load, valutazione della densità media dei vari litotipi).
Tutti i dati litotecnici sono stati poi utilizzati per realizzare una carta litotecnica, in cui sono state distinte le varie Unità Litologico Tecniche (ULT). In base alle evidenze risultanti dalla carta geologica, geomorfologia e litotecnica, è stata inoltre realizzata una carta di sintesi, che individua le aree per le quali è possibile un’amplificazione sismica, connessa alle proprietà del sito.
La carta non delimita zone ordinate secondo criteri di pericolosità crescente, ma evidenzia le aree per le quali le particolari situazioni geologico-geomorfologiche possono determinare amplificazione sismica
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
Process and Product Quality Optimization with Explainable Artificial Intelligence
No full textIn today's rapidly evolving technological landscape, businesses across various industries face a critical challenge: maintaining and enhancing the quality of both their processes and the products they deliver. Traditionally, this task has been tackled through manual analysis, statistical methods, and domain expertise. However, with the advent of artificial intelligence (AI) and machine learning, new opportunities have emerged to revolutionize quality optimization. This chapter explores the process and product quality optimization in a real industrial use case with the help of explainable artificial intelligence (XAI) techniques. While AI algorithms have proven their effectiveness in improving quality, one of the longstanding barriers to their widespread adoption has been the lack of interpretability and transparency in their decision-making processes. XAI addresses this concern by enabling human stakeholders to understand and trust the outcomes of AI models, thereby empowering them to make informed decisions and take effective actions
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
A methodology to guide companies in using Explainable AI-driven interfaces in manufacturing contexts
Full text linkNowadays, the increasing integration of artificial intelligence (AI) technologies in manufacturing processes is raising the need of users to understand and interpret the decision-making processes of complex AI systems. Traditional black-box AI models often lack transparency, making it challenging for users to comprehend the reasoning behind their outputs. In contrast, Explainable Artificial Intelligence (XAI) techniques provide interpretability by revealing the internal mechanisms of AI models, making them more trustworthy and facilitating human-AI collaboration. In order to promote XAI models' dissemination, this paper proposes a matrix-based methodology to design XAI-driven user interfaces in manufacturing contexts. It helps in mapping the users' needs and identifying the “explainability visualization types” that best fits the end users' requirements for the specific context of use. The proposed methodology was applied in the XMANAI European Project (https://ai4manufacturing.eu), aimed at creating a novel AI platform to support XAI-supported decision making in manufacturing plants. Results showed that the proposed methodology is able to guide companies in the correct implementation of XAI models, realizing the full potential of AI while ensuring human oversight and control
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
