Fuzzy ServPerf model combined with ELECTRE III to comparatively evaluate service quality of international airports in Sicily
2015
In this paper a new approach was proposed so as to comparatively evaluate the quality of service alternatives. In particular, a fuzzy extension of the ServPerf service conceptual model was considered to estimate quality scores of fundamental service criteria, whereas the non-compensative multi-criteria decision-making ELECTRE III method was employed to point out the quality ranking of service alternatives on the basis of which the comparative service quality analysis was performed. In order to show the effectiveness of the proposed approach, an empirical study concerning service quality evaluation of the three international airports in Sicily (Italy) was conducted with detailed proposals fo…
Removal of old protein layers from surfaces of works of art by new enzymes
2012
The aim of the present project is to set up bio-cleaning protocols in order to easily remove altered protein layers (e.g. animal glues) by enzymatic proteins (proteases). Protein molecules were isolated from marine invertebrate organisms, characterized by size exclusion highpressure liquid chromatography (Waters: SEC-HPLC, BioSuite 250 to 10㎛ SEC 7.5 x 300 mm) and their gelatinase activity analyzed by zymography on polyacrilamide gel. The remarkably proteolytic activity and the reaction temperature range of these enzymes, 4° to 37℃, made it possible to hypothesize their use in bioremediation projects. Tests were performed on protein coating found on some polychrome wooden artifacts exposed …
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 From the content of some unpublished documents and also some rather less-well-known papers by Lotfi A. Zadeh it is argued that the emergences of Computer science and Fuzzy Set Theory have been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.
Algorithmic paradigms for stability-based cluster validity and model selection statistical methods, with applications to microarray data analysis
2012
AbstractThe advent of high throughput technologies, in particular microarrays, for biological research has revived interest in clustering, resulting in a plethora of new clustering algorithms. However, model selection, i.e., the identification of the correct number of clusters in a dataset, has received relatively little attention. Indeed, although central for statistics, its difficulty is also well known. Fortunately, a few novel techniques for model selection, representing a sharp departure from previous ones in statistics, have been proposed and gained prominence for microarray data analysis. Among those, the stability-based methods are the most robust and best performing in terms of pre…
On the Evaluation of Images Complexity: A Fuzzy Approach (revised and expanded)
2006
The inherently multidimensional problem of evaluating the complexity of an image is of a certain relevance in both computer sci- ence and cognitive psychology. Computer scientists usually analyze spa- tial dimensions, to deal with automatic vision problems, such as feature- extraction. Psychologists seem more interested in the temporal dimension of complexity, to explore attentional models. Is it possible, by merging both approaches, to define an more general index of visual complexity? We have defined a fuzzy mathematical model of visual complexity, using a specific entropy function; results obtained by applying this model to pictorial images have a strong correlation with ones from an exp…
Destinazione dei beni pubblici e teoria del provvedimento amministrativo
2020
Il contributo esamina la teoria del provvedimento amministrativo elaborata dalla dottrina giuspubblicistica, soprattuto da Scoca, per valutarne la rilevanza rispetto ad una particolare categoria di atti amministrativi, gli atti di destinazione dei beni pubblici.
Commento agli articoli 543-566
2016
Il lavoro consiste in un commento a tutte le disposizioni del codice di procedura civile in materia di espropriaizone presso terzi, con richiami alle principali leggi speciali, e in un commento alle norme del codice di procedura civile sul pignoramento immobiliare e sull'intervento dei creditori nella espropriazione immobiliare The essay is a commentary on civile procedure rules concernig enforcement of civil obbligation, with reference to the seizure of debtors's credit towards other people (e.g. attaching of erarnings) and with respect to the seizure of real estate.

A decomposition theorem for σ-P-directionally porous sets in Fréchet spaces
2007
In this paper we study suitable notions of porosity and directional porosity in Fréchet spaces. Moreover we give a decomposition theorem for $\sigma$-$\mathcal{P}$-directionally porous sets.
