Restoration of a XVII Century’s predella reliquary: From Physico-Chemical Characterization to the Conservation Process

2021

We report on the restoration of a XVII century’s predella reliquary, which is a part of a larger setup that includes a wall reliquary and a wooden crucified Christ, both belonging to the church of “Madre Maria SS. Assunta”, in Polizzi Generosa, Sicily, Italy. The historical/artistic and paleographic research was flanked successfully by the scientific objective characterization of the materials. The scientific approach was relevant in the definition of the steps for the restoration of the artefact. The optical microscopy was used for the identification of the wood species. Electron microscopy and elemental mapping by energy-dispersive X-ray (EDX) was successful in the identification of the l…

Contributions à l'analyse et à l'interprétation des images : Extraction et représentation de caractéristiques

2016

Ce mémoire, rédigé en vue de l'obtention de l'Habilitation à Diriger des Recherches (HDR), offre un aperçu des travaux de recherche et d’encadrement que j’ai pu mener depuis l'obtention de mon doctorat. Il montre la diversité des champs d’application et de recherche (en vision et en imagerie médicale) que j’ai pu couvrir , ainsi que mon implication dans l’encadrement doctoral.Mes activités de recherche se divisent en deux grandes parties. D'une part, l'analyse de scènes dynamiques, à savoir la détection de regions d'intérêt dans des séquences d'images, pour réduire la taile des données à traiter, et la détection et le suivi d'objets mobiles à l'aide de caméras de diverses natures (perspecti…

Why Use Interactive Multi-Objective Optimization in Chemical Process Design?

2008

Problems in chemical engineering, like most real-world optimization problems, typically, have several conflicting performance criteria or objectives and they often are computationally demanding, which sets special requirements on the optimization methods used. In this chapter, we point out some shortcomings of some widely used basic methods of multi-objective optimization. As an alternative, we suggest using interactive approaches where the role of a decision maker or a designer is emphasized. Interactive multi-objective optimization has been shown to suit well for chemical process design problems because it takes the preferences of the decision maker into account in an iterative manner tha…

Oggetti narrati, oggetti narranti. Le scarpe come simbolo, racconto e rappresentazione

2022

Gli oggetti hanno voce, se hanno vita. Bisogna prima interrogarsi sulla vita delle cose per poter ascoltare le loro voci. Mettendo a fuoco un caso esemplare, le scarpe, si prenderanno in considerazione sia gli oggetti narrati nei componimenti letterari, sia gli oggetti narranti, cioè quegli oggetti simbolici che sono capaci di raccontare uno stile di vita. Infine si esaminerà la relazione tra design e narrazione al fine di evidenziare le strategie e dispositivi narrativi attraverso cui il designer riesce a rendere significante la voce degli oggetti nelle istallazioni artistiche. Objects have a voice, if they have a life. We need earlier to think of the life of things in order to listen to t…

Análisis de los antecedentes histórico-filosóficos de la "paradoja cognitiva de Duval"

2015

In a famous article published in 1993, Raymond Duval highlighted a simple fact: the student may confuse the mathematical object O he is trying to build cognitively with one of its semiotic representations R(O). Duval explained that this confusion was due to a sort of inevitable paradox: only someone who has already built O, can recognize R(O) as a representation of O and not as an object in itself. Thereafter, this thought has been extremely influential for researchers. However, even if in different terms, many scholars of semiotics have emphasized the same phenomenon. In this paper we propose to remind some of them. En un famoso artículo publicado en 1993, Raymond Duval evidenciaba el sigu…

Apprendre à manger. Sémiotique des objets de table pour enfants

2021

The subject of children at the table is related to that of conviviality on two levels. Firstly, at the level of the acquisition of social rules concerning the ways of being at the table, the codes of the meal, the recognition of appropriate behaviour in different contexts (at home, outside, formal, informal, etc.), in short, the "have to". Secondly, at the level of the acquisition of a general know-how, represented by all the somatic behaviours necessary for the consumption of the meal: learning to chew solid food, to drink from a glass, to use cutlery, to handle plates, bowls, soup plates, and so on. In this essay, we will analyse table objects designed for children (glasses, cutlery, plat…

« L’homme-à-fourchette ». La construction du convive-modèle à la table de Buckingham Palace

2021

“Every meal is a lesson learned”. The Victorian saying warns of the risk of punishment that every guest constantly incurs. These sanctions often relate to the way in which one approaches, one selects, one handles the cutlery on the table. Indeed, the construction of the ideal guest, of his way of being with others and of behaving in relation to food, often and above all involves being a "model user" of table service. We will analyze this aspect from the images and speeches posted on the Windsors' Twitter account, the official websites of the Royal Family and the manners manuals they sponsor. Each of these supports manifests an aspect of the subjectivity of the ideal guest as a model-user of…

Investigating the Structure of Vela X

2018

Vela X is the prototypical example of a pulsar wind nebula whose morphology and detailed structure have been affected by the interaction with the reverse shock of its host supernova remnant. The resulting complex of filamentary structure and mixed-in ejecta embedded in a nebula that is offset from the pulsar provides the best example we have of this middle-age state that characterizes a significant fraction of composite SNRs, and perhaps all of the large-diameter PWNe seen as TeV sources. Here we report on an XMM-Newton Large Project study of Vela X, supplemented by additional Chandra observations. Through broad spectral modeling as well as detailed spectral investigations of discrete emiss…
