Electrical Safety Analysis in the Presence of Resonant Grounding Neutral
2019
The resonant grounding is one of the possible methods of the system neutral grounding for the medium voltage distribution. IEEE standards do define this grounding configuration, but important advantages and drawbacks of the resonant grounding might not be fully known, due to its rather uncommon application in North America. On the other hand, resonant grounding in Europe is imposed by the increased requirements for power quality, especially for medium-voltage (MV) industrial users, imposed to electric utilities by regulatory authorities, with the purpose to protect the interests of users and consumers. Level of the continuity of the service, magnitude and phase of ground-fault currents, mag…
CONOSCENZA E CONSERVAZIONE. PROSPETTIVE PER LE DOMUS DI PIAZZA DELLA VITTORIA A PALERMO.
2014
Il tema di ricerca possiede un carattere multidisciplinare, coinvolge ampi settori e, con un approccio metodologico di tipo olistico, mette in evidenza le complessità storiche, artistiche, architettoniche, archeologiche e urbanistiche, tenendo conto delle differenti implicazioni sul piano sia tecnologico che museografico. Il caso di studio scelto, per elaborare una strategia d’intervento e riproponibile in altri contesti, è costituito dalle Domus di Piazza della Vittoria a Palermo, un exemplum di complesso residenziale unico nell’ambito della città, arricchito dalla presenza di importanti mosaici che testimoniano la circolazione di possibili culti praticati nell’area occidentale della Sicil…

Contributions à l’imagerie polarimétrique et à ses applications en vision pour la robotique
2019
Ce mémoire présente le bilan de l'ensemble de mes travaux de recherche effectués de septembre 2006 à juin 2019 au sein de l'équipe Creusotine du laboratoire Le2i devenue équipe Vibot ERL CNRS 6000 depuis janvier 2018. Les principales activités de recherche que j'ai menées au cours de ces 10 dernières années autour de l'imagerie polarimétrique, de la vision omnidirectionnelle et de leurs applications en vision pour la robotique seront particulièrement détaillées dans ce document. Elles seront présentées selon deux grandes parties : la première concernera plutôt l'aspect mise en œuvre et calibrage des caméras et la seconde se concentrera sur les applications potentielles en vision pour la rob…

Timbral Qualities of Semantic Structures of Music.
2010
The rapid expansion of social media in music has provided the field with impressive datasets that offer insights into the semantic structures underlying everyday uses and classification of music. We hypothesize that the organization of these structures are rather directly linked with the ”qualia” of the music as sound. To explore the ways in which these structures are connected with the qualities of sounds, a semantic space was extracted from a large collection of musical tags with latent semantic and cluster analysis. The perceptual and musical properties of 19 clusters were investigated by a similarity rating task that used spliced musical excerpts representing each cluster. The resulting…
Métodos para la caracterización del sistema de revisión por pares de artículos científicos
2022
El proceso de revisión por pares constituye una pieza clave de los engranajes que componen el sistema de publicación de la ciencia. Este vela por la calidad, integridad, reproducibilidad y robustez de los trabajos que se envían a las revistas científicas y es objeto continuo de estudio y discusión en la comunidad científica, involucrando a autores, editores y revisores en una tarea conjunta plagada de procesos sociales que se manifiestan a modo de negociación entre las diferentes partes, asumiendo el editor el papel de árbitro. A su vez, el proceso de revisión por pares es la insignia de calidad de las propias revistas. Mantener unos altos estándares y hacer del sistema de revisión un eleme…
Analysis of microtomographic images of porous heterogeneous materials
2015
In this work, we study the phases of image processing chain of microtomographic imag- ing in order to obtain reliable results while optimizing the time spent on denoising and segmentation. We consider that the decisions made at the early phases of the processing chain are most important and the selection made there essentially determine the overall quality of imaging process. We also compare here various denoising method qualita- tively, however, we think that the pure noise removal ability is not the only requirement for noise removal in microtomographic images. By proper denoising we can affect selec- tion of segmentation methods and, thus, also the quality of the analysis. Additionally, …
Dynamic assessment of word derivational knowledge: Tracing the development of a learner
2016
The present paper reports on a case study that explored the applicability of dynamic assessment (DA) for promoting learners’ word derivational knowledge in English as a second or a foreign language (L2). One learner’s performance on tasks assessing his word derivational knowledge was measured four times. The first two measurements were conducted before and after three weekly human-mediated DA sessions and the last two, which took place a year and a half later, before and after three weekly computerised DA sessions. Think aloud protocols and interviews were used to trace changes in the learner’s use of strategies and knowledge sources. The results revealed that following the dynamic assessme…
Cognitive Linguistics as the Underlying Framework for Semantic Annotation
2012
In recent years many attempts have been made to design suitable sets of rules aimed at extracting the semantic meaning from plain text, and to achieve annotation, but very few approaches make extensive use of grammars. Current systems are mainly focused on extracting the semantic role of the entities described in the text. This approach has limitations: in such applications the semantic role is conceived merely as the meaning of the involved entities without considering their context. As an example, current semantic annotators often specify a date entity without any annotation regarding the kind of the date itself i.e. a birth date, a book publication date, and so on. Moreover, these system…
