A user-friendly control system to easy reconfigure a manufacturing cell
2006
Generic manufacturing enterprises need to interact with an environment characterized by a strong competition. In order to react to the mutable requests of market, control systems should confer to the manufacturing system capabilities for easy modifiability, and this can be achieved by reducing the necessary time to reconfigure the existing system. Following this main requirement, this paper presents a user-friendly control system that pursues three operational goals: - Ability to easy re-program the sequence of operations of the manufacturing equipments of a manufacturing cell; - Reconfigurability of the system, by allowing to add/remove a new/existing component in/from the manufacturing ce…
·En la carne desnuda la escarcha". Modalización lírica y construcción simbólica en la poesía de José Hierro
2011
En la Tesis Doctoral “En la carne desnuda la escarcha”. Modalización lírica y construcción simbólica en la poesía de José Hierro se lleva a cabo un recorrido por la obra poética del santanderino de adopción Pepe Hierro (1922-2002) mediante el cual se confirma la hipótesis de que su poesía puede dividirse en dos épocas creativas diferenciadas, correspondientes a dos poéticas también diferentes. Para ello, se analiza la obra del poeta desde dos perspectivas básicas en todo discurso lírico: la modalización lírica y los procedimientos simbólicos que se construyen. Según ambas perspectivas es posible, en efecto, determinar un punto de inflexión en su poesía y delimitar en ella, por tanto, dos mo…
Vibrational circular dichroism studies of exceptionally strong chirality inducers in liquid crystals.
2021
7,7′-Disubstituted 2,2′-methylenedioxy-1,1′-binaphthyls are highly efficient chirality inducers in nematic liquid crystals. The absolute configuration of these compounds is, however, hard to determine as they only crystallize as racemic mixtures. In this work a Vibrational Circular Dichroism (VCD) study is reported that provides an unambiguous determination of the absolute configuration of these compounds. An in-depth General Coupled Oscillator (GCO) analysis of the source of the VCD signal reveals that the unusual structure of these binaphthyl compounds inherently leads to strong and robust VCD bands. Combined with linear transit calculations, our VCD studies allow for the determination of…
Vibrational circular dichroism spectroscopy for probing the expression of chirality in mechanically planar chiral rotaxanes
2020
Mechanically interlocked molecules can exhibit molecular chirality that arises due to the mechanical bond rather than covalent stereogenic units. Developing applications of such systems is made challenging by the absence of techniques for assigning the absolute configuration of products and methods to probe how the mechanical stereogenic unit influences the spatial arrangements of the functional groups in solution. Here we demonstrate for the first time that Vibrational Circular Dichroism (VCD) can be used to not only discriminate between mechanical stereoisomers but also provide detailed information on their (co)conformations. The latter is particularly important as these molecules are now…
OLTRE IL LEGAME. GENITORI E FIGLI NEI NUOVI SCENARI FAMILIARI
2014
I repentini cambiamenti che la famiglia attuale attraversa da alcuni decenni riguardano ogni aspetto della sua configurazione e struttura, rendendo necessaria una prospettiva complessa e multidisciplinare indispensabile alla sua comprensione. Le relazioni intra-familiari e inter-sistemiche, i criteri di normatività e funzionalità, lo stesso significato del termine famiglia sono in continua mutazione, arricchendosi di nuove sfumature e declinandosi in nuovi scenari. Il sottosistema filiale non è immune da tali trasformazioni, e la relazione genitore-figlio deve essere riformulata alla luce di tali più ampi cambiamenti. La famiglia attuale, dunque, può presentarsi oggi profondamente different…
Pour une approche qualitative du sensible
2016
International audience; En sciences humaines et sociales, une production extrêmement abondante concerne l’attractivité et la valorisation du sensoriel et du sensible sur un plan anthropologique (Laplantine, 2005 ; Auge, 2014), sociologique (Le Breton, 2006 ; Lipovestky, 2015), en sémiotique (Landowski, 1998 ; Fontanille, 2004) ou en marketing (Giboreau, 2008), sans même aller chercher des ressources psychologiques ou psychanalytiques. Dans sa richesse et sa complexité, dans l’unité aussi à rechercher, au sein du sensible, ce sont autant d’objets et d’espaces qui s’ouvrent pour la recherche en communication, que de problématiques d’ordre épistémologique, conceptuel, méthodologique, opératoir…
De la pertinence de l'adjectif "étrangère" en Didactique des Langues-Cultures
2012
Les statuts traditionnellement attribués aux langues (ancienne/moderne, morte/vivante, maternelle/étrangère) continuent de remplir leurs fonctions : opposer, ordonner, identifier acteurs et spécialistes de chaque domaine. De leur côté, « Français Langue Etrangère » et « FLE », après des débuts difficiles, connaissent un succès tel que l’on oublie les idées qu’ils véhiculent et leur adaptation nécessaire à une diversité linguistique et culturelle croissante. Dans le contexte de l’apprentissage effectif et durable des langues-cultures du monde, impossible sans processus de familiarisation, la pertinence de l’adjectif « étrangère » est discutable. Accorder une valeur maximale aux qualificatifs…
Implementing Ethics in AI: Initial Results of an Industrial Multiple Case Study
2019
Artificial intelligence (AI) is becoming increasingly widespread in system development endeavors. As AI systems affect various stakeholders due to their unique nature, the growing influence of these systems calls for ethical considerations. Academic discussion and practical examples of autonomous system failures have highlighted the need for implementing ethics in software development. However, research on methods and tools for implementing ethics into AI system design and development in practice is still lacking. This paper begins to address this focal problem by providing elements needed for producing a baseline for ethics in AI based software development. We do so by means of an industri…
Towards realistic artificial benchmark for community detection algorithms evaluation
2013
Many algorithms have been proposed for revealing the community structure in complex networks. Tests under a wide range of realistic conditions must be performed in order to select the most appropriate for a particular application. Artificially generated networks are often used for this purpose. The most realistic generative method to date has been proposed by Lancichinetti, Fortunato and Radicchi (LFR). However, it does not produce networks with some typical features of real-world networks. To overcome this drawback, we investigate two alternative modifications of this algorithm. Experimental results show that in both cases, centralisation and degree correlation values of generated networks…
