Fundamentals of a Generalized Measure Theory

1999

In this chapter, we try to present a coherent survey on some recent attempts in building a theory of generalized measures. Our main goal is to emphasize a minimal set of axioms both for the measures and their domains, and still to be able to prove significant results. Therefore we start with fairly general structures and enrich them with additional properties only if necessary.

Developing a scuba trail vulnerability index (STVI): a case study from a Mediterranean MPA

2008

Scuba diving is now one of the major form of commercial use of marine protected areas (MPAs) around the world and the control of its potential impacts on the marine environment represents a fundamental key to manage this recreational activity in highly dived areas. A potential tool to tackle such issues has been thought to be the definition of a value of recreational carrying capacity of an area, but this approach has been rarely considered management-effective. Therefore, the first step for effectively managing scuba-diving should be ‘bottom-up’: characterizing the benthic communities potentially affected by diving and evaluating their vulnerability. Aim of this paper is to propose a tool …

Verso le Città Cognitive. Un esempio di classificatore fuzzy: il bot parcheggiatore

Le città cognitive (Portmann, Seising e Tabacchi, 2017) sono una possibile evoluzione delle smart cities (Portmann e Fingers, 2016). Nella progettazione di una città cognitiva si tiene conto, oltre che della rete di sensori ed attuatori che contribuiscono alla condivisione dei dati, anche del rapporto tra la città ed il cittadino; a questo fine sono utilizzate una serie di tecnologie proprie della Computational Intelligence (Kacprzyk e Pedrycz, 2015), quali Metaeuristiche, Algoritmi evolutivi e genetici e metodologie Soft Computing per includere nel dialogo non solo vaste moli di dati, ma la possibilità di analisi introspettive che utilizzino come interfaccia da e verso gli utenti i linguag…

A Fuzzy One Class Classifier for Multi Layer Model

2009

The paper describes an application of a fuzzy one-class classifier (FOC ) for the identification of different signal patterns embedded in a noise structured background. The classification phase is applied after a preprocessing phase based on a Multi Layer Model (MLM ) that provides a preliminary signal segmentation in an interval feature space. The FOC has been tested on synthetic and real microarray data in the specific problem of DNA nucleosome and linker regions identification. Results have shown, in both cases, a good recognition rate.

The Webbed Emergence of Fuzzy Sets and Computer Science Education from Electrical Engineering

2013

Historically, Computer science emerged from electrical engineering and from mathematics in the 1960s. From the content of some unpublished documents and also some rather less-well-known papers by Lotfi A. Zadeh it is argued that the emergences of Computer science and Fuzzy Set Theory have been interlinked. Zadeh’s task as Chair of the Electrical Engineering Department in Berkeley in the 1960s, his activities in Education of Engineering and his creation of the theory of Fuzzy sets generated his view on the scientific discipline of Com- puter science as a fuzzy set. This view could establish a new approach to history and philosophy of science.

Birkhoff's aesthetics, Arnheim's entropy. Some remarks on complexity and fuzzy entropy in arts

2015

A judgement of aesthetic in arts is, by sheer consensus, a daunting task that requires evaluation of a whole host of endogenous and exogenous cultural factors. A few of them can actually provide very useful hints in tackling foundational problems in Information Science in a more natural setting than what is usually provided by a typical engineering stance. This interaction can however work the other way about, as instruments from the Information and Computer Science toolkit may help in focusing the less explored features of art and its evaluation. When all the social, historical, hermeneutical and political considerations are stripped from the living flesh of the piece, we lose most of wha…

An analysis System based on Morphological Fuzzy Filters: Application to the study of Marine Pollution Due to Hydrocarbons

Future is where concepts, theories and applications meet (also in fuzzy logic)

2015

No one knows where the future lies, and the idea of serendipity in science is now raised to something of a tropism. This does not impede our will to predict, if not the exact events, at least the short–term trends in the disciplines we live and breathe, and to point at the (subjective) glaring chances for a bright future. This volume is a clear example of the need that any living scientific discipline has for constant regrouping and redirection, in a never–ending process of consolidating results and finding new paths. In this contribution we will try and focus on a number of areas of fuzzy logic and, by extension, in the whole word of uncertainty, where (in our opinion) a number of interest…

Teoria dei Concetti e Teoria degli Insiemi Fuzzy

Nel presente articolo, redatto in forma di position paper, si intende sottoli- neare una serie di possibili sviluppi futuri di questa relazione, ed evidenziare come alcuni degli ostacoli alla definizione di una ToC che rifletta la ricchez- za e la creatività dell‘uso dei concetti nella comunicazione umana possano essere affrontati con l‘aiuto della FST.

Reflections on Technology and Human Sciences: rediscovering a common thread through the analysis of a few epistemological features of fuzziness

2013

A number of reasons, both historical and philosophical, has caused Technology and Human Sciences to be perceived as disjoint domains. In opposi- tion, we claim that there exists a strong methodological affinity between these apparently disconnected fields of knowledge. Our view is further corroborated by new hints from Information Sciences, in which new scientific concepts and tools such as fuzziness have emerged. Comparing the ways in which both Technology and Literature offer a model of reality we shall see that their approaches preserve a strong connection with the “description” of the pieces of reality they aim to model, against the Galileian hard sciences’ approach of making bold hypot…
