Image classification based on 2D feature motifs
2013
The classification of raw data often involves the problem of selecting the appropriate set of features to represent the input data. In general, various features can be extracted from the input dataset, but only some of them are actually relevant for the classification process. Since relevant features are often unknown in real-world problems, many candidate features are usually introduced. This degrades both the speed and the predictive accuracy of the classifier due to the presence of redundancy in the candidate feature set. In this paper, we study the capability of a special class of motifs previously introduced in the literature, i.e. 2D irredundant motifs, when they are exploited as feat…

Sistemas híbridos orgánicos-inorgánicos en films de Langmuir-Blodgett
2002
ÉCe travail porte sur la formation et la caractérisation de nouveaux systèmes organiques-inorganiques par l'utilisation de films de Langmuir et de la technique de Langmuir-Blodgett. Plusieurs voies ont ainsi été explorées afin d'obtenir des films minces hybrides aux propriétés multiples, en particulier magnétiques. L'utilisation de l'interaction entre monocouches cationiques et des anions présents en sous-phase a ainsi permis l'organisation de différents polyanions inorganiques en structure lamellaire. Cette stratégie a ensuite été généralisée au cas de colloïdes de Bleu de Prusse, composés bimétalliques étendus. Une large étude (de la préparation à la caractérisation) a été consacrée à ces…
Sémiotique et pandémie : journal intime
2020
Au lieu d’une réflexion a posteriori sur la période de la pandémie Covid-19, je présente ici quelques extraits d’un journal que j’ai tenu pendant les mois plus tragiques (jusqu’à ce moment) du confinement. L’épiphanie du virus a modifié presque tout dans notre vie quotidienne, et une bonne partie de ce « tout » concerne spécifiquement la signification. D’où l’intérêt du sémioticien. Du point de vue médiatique, l’épidémie est une aubaine. La bad news qui est une good news. La malchance foudroyante qui rapporte énormément. Une nouvelle appétissante qui attire l’attention du public blasé, qui multiplie l’audience et avance – bien davantage que son objet – par contagion immédiate : tout le mond…
How Do Proverbs Get Their Meanings? The Model of Interpretation Based on a Metaphor Theory.
2011
The constellation of proverbs is quite permanent. Only one third of proverbs are supposed to change in about one hundred years (Kuusi 1994: 117−118). This means that the proverbs used in the 21st century are much the same as the proverbs in the beginning of the 20th century and quite the same as in 1850’s. In this article I focus on the proverb as a significant unit. Even if the proverbs are unchangeable, their meanings are not. The proverbial expressions can be looked from at least four stand points: (1) What is the proverb decoded to mean? (2) What do the words mean? (3) What does the speaker mean? (4) How does the listener interpret the proverb? With all the four ways there are some weak…
Heavy-Ion-Induced Degradation in SiC Schottky Diodes : Incident Angle and Energy Deposition Dependence
2017
Heavy-ion-induced degradation in the reverse leakage current of SiC Schottky power diodes exhibits a strong dependence on the ion angle of incidence. This effect is studied experimentally for several different bias voltages applied during heavy-ion exposure. In addition, TCAD simulations are used to give insight on the physical mechanisms involved. peerReviewed
Problemes epistemològics dels condicionants prelingüístics
1994
Les reflexions que segueixen se situen en les fronteres entre ontologia, epistemologia i filosofia del llenguatge. No pot sorprendre aquesta situació: el més habitual és que els problemes filosòfics siguen problemes fronterers o, dit d'altra manera, que la reflexió filosòfica situe sempre els seus problemes allà on més s'emboliquen. The object of this paper is to carry out a criticat anatysls of the epistemological foundations of those extralinguistic elements to which it is necessary to resort in order to give an account of communication, both intratinguistic and interlinguistic. The paint of view adopted is exclusively philosophical, within the field of problems of philosophy of language,…
Mater semper certa est ? Passé, présent, avenir d'un adage, Actes du colloque de Dijon des 24-25 novembre 2016, K. Fiorentino et A. Fiorentino (dir.)…
2018
International audience; La preuve de la filiation maternelle, résumée par l’un des adages les plus connus en droit de la famille, Mater semper certa est, a pendant longtemps semblé être une évidence voulue par la nature, donc ne posant que peu de problème juridique, à l’inverse de la paternité. Pourtant, l’évidence a-t-elle toujours été aussi flagrante ? Pourquoi ressentir le besoin de forger un adage ? Quelle fut sa valeur et a-t-il toujours parfaitement reflété la réalité ? Force est de constater que si la maternité est certaine, la preuve de celle-ci se heurte à plusieurs difficultés tant matérielles que processuelles. Il s’agit donc ici de s’interroger sur la place accordée en droit à l…
Linear Types for Higher Order Processes with First Class Directed Channels
1995
Abstract We present a small programming language for distributed systems based on message passing processes. In contrast to similar languages, channels are one-to-one connections between a unique sender and a unique receiver process. Process definitions and channels are first class values and the topology of process systems can change dynamically. The operational semantics of the language is defined by means of graph rewriting rules. A static type system based on the notion of linear types ensures that channels are always used as one-to-one connections.
Naming sensory impressions in winespeak between professionals and non-professionals
2014
International audience; Connections between semantics — for instance, cognitive semantic models such as prototype theory — and sensory analysis have often been studied from an interdisciplinary perspective involving disciplines such as linguistics, cognitive psychology, and chemistry. Among the many fields concerned with this topic, this paper will focus on the particular case of winespeak and especially on the co-construction of a shared knowledge between professionals and consumers. The hypothesis to be verified is (i) that objectivist and strict terminological approaches can not account for the processes at work when professionals and non professionals try to agree on the ‘specialized me…
