Testing Ikonos and Landsat 7 ETM+ Potential for Stand-Level Forest Type Mapping by Soft Supervised Approaches
2003
Forest types can be adopted as a suitable reference for classifying survey units within multipurpose forest resources inventories, at the properly considered level. This kind of hierarchical classification approach integrates an ecologically meaningful per-habitat perspective with practical survey, planning and management requirements. Advanced remote sensing technologies can be valuable tools for a cost-effective implementation of such an approach. In the present paper, data from high (Landsat 7 ETM+) and very high (Ikonos) spatial resolution satellite sensors were tested to understand their potential contribution supporting stand-level forest type mapping under Mediterranean conditions. I…
Varieties of Vagueness, Fuzziness and a few foundational (and ontological) questions
2011
In this paper we discuss the multifaceted nature of vagueness, the limits of (standard) set theory in dealing with the foundational aspects that a really innovating theory of vagueness should manifest, and the difficul- ties in outlining the possible features that such a type of new formalism should exhibit in order to be able to deal with such innovative aspects. We shall highlight some aspects of the role that Fuzzy Set Theory (FST) can play in this process.

Specificities and Vagaries of Medicine from the Viewpoint of Hard Sciences
2013
Among many other beautiful reflections on the ontology of medicine, in his Handbook of Analytic Philosophy of Medicine, Sadegh Zadeh promotes Fuzzy Sets Theory among the basic instruments of logic for medical understanding, highlights the importance of vagueness in the medical language and as an intrinsic property of medical epistemology, and invokes the clear advantages of a medical fuzzy taxonomy to overcome the binary concept of being healthy/ill. We briefly discuss these aspects, relating them to the peculiarity of Fuzziness as the only purely scientific notion among the foundational tools needed to define an analytic philosophy of medicine more concerned with an explicatum of the notio…
Human error contribution to accidents in the manufacturing sector: A structured approach to evaluate the interdependence among performance shaping fa…
2023
Since the 1970s, Human Reliability Analysis (HRA) methods have received a great interest for the quantification of the Human Error Probability (HEP) in Nuclear Power Plants (NPPs). To this purpose, the second-generation HRA methods consider contextual and cognitive factors - named Performance Shaping Factors (PSFs) - that may influence the workers’ performance during tasks execution. Despite the recent extension of HRA methods to different fields, only few studies refer to the manufacturing sector. In addition, the majority of contributions assume the independence among PSFs, which may result in an over or under estimation of HEP. Therefore, the present paper focuses on the manufacturing se…
Qualità dell’aria: il Fuzzy Environmental Analogy Index Model (FEAIM) per valutare l’idoneità delle stazioni ai fini modellistici
2020
Tutte le attività volte a studiare le cause primarie e gli effetti dell’inquinamento atmosferico richiedono l’impiego di una rete di monitoraggio della qualità dell’aria ottimizzata per la valutazione dell’esposizione dei bersagli recettori agli effetti degli inquinanti aerodispersi. Nell’ambito di una collaborazione tra ARPA Sicilia e il Dipartimento di Ingegneria dell’Università di Palermo, sono state condotte ricerche per sviluppare una metodologia innovativa utile per ottimizzare l’assetto delle reti di monitoraggio della qualità dell’aria su scala regionale. L’approccio metodologico si fonda su un nuovo indice, chiamato indice di analogia ambientale del territorio (FEAI), basato sulla …

Evaluation of capabilities of fuzzy logic classification of different kind of data
2008
In this paper, in order to evaluate the capability of several data, acquired by different sensors, some object-oriented classification tests have been carried out. In particular, the results obtained with two RGB ortophotos, acquired with traditional methodology, have been compared with the ones obtained with two QuickBird images and with the ones obtained by ADS40 pushbroom sensor. The object classification is based on two next steps: The classification to objects is based on two next steps: the decomposition of the whole image in dimension objects bigger than the pixel, procedure called segmentation, and the next classification with Fuzzy logic. This approach provides more reliable result…
The Linguistic Continua
2022
There is no doubt that there are inferential chains that break, and sometimes break suddenly. For instance, provided p and q are synonyms, that is, their respective meanings are contextually indistinguishable under the definition.
