Operators in Rigged Hilbert Spaces, Gel’fand Bases and Generalized Eigenvalues
2022
Given a self-adjoint operator A in a Hilbert space H, we analyze its spectral behavior when it is expressed in terms of generalized eigenvectors. Using the formalism of Gel’fand distribution bases, we explore the conditions for the generalized eigenspaces to be one-dimensional, i.e., for A to have a simple spectrum.
Ecologia e selvicoltura dei boschi artificiali di conifere dei Monti Sicani (Sicilia)
2009
I rimboschimenti realizzati in Sicilia dopo il 1950 hanno contribuito notevolmente all’aumento della superficie forestale nell’Isola. In questo lavoro sono descritte e analizzate le caratteristiche ecologiche e selvicolturali dei rimboschimenti localizzati all’interno dei principali siti della Rete Natura 2000 dei Monti Sicani, con l’obiettivo di formulare idonee linee guida di gestione forestale sostenibile finalizzata ad aumentare la loro stabilità ecologico-strutturale e a favorire così i processi di rinaturalizzazione, diffusi spontaneamente in molte aree. L’indagine conoscitiva è stata condotta in ambiente GIS attraverso l’overlay tra la distribuzione dei rimboschimenti, classificati a…
Investigation of a Gravel-Bed River’s Pattern Changes: Insights from Satellite Images
2021
Changes in river pattern have been documented in the literature. The recognition of islands and vegetated patches, which is indicative of the evolution processes, requires simultaneous information at different points and at different times and field studies are still difficult and scarce. The present work, focusing the attention on a gravel-bed river, explores the possibility to conduct a first-step pattern changes analysis by identifying the evolution of the morphological features and taking information of islands and vegetated patches from satellite images easily available from Google Earth. The study is conducted by combining the information taken from both the satellite images and the f…

Modeling ontologies for robotic environments
2002
On the basis of a multiple abstraction levels specification process, we developed a representational model for environmental robotic knowledge through the definition of a set of ontologies using a multi perspective approach. A general ontological model for typical indoor environments has been first developed, followed by its specialization using an implementation perspective. Actual software implementation of the ontology has been obtained via a XML-based markup language, used to build a repository for robotic environmental knowledge. Copyright 2002 ACM.
Rilkean Memories and the Self of a Robot
2019
This paper discusses the concept of Rilkean memories, recently introduced by Mark Rowlands, to analyze the complex intermix of hardware and software related to the self of a robot. The Rilkean memory of an event is related to the trace of that episode left in the body of the individual. It transforms the act of remembering into behavioral and bodily dispositions, thus generating the peculiar behavioral style of the individual, which is at the basis of her autobiographical self. In the case of long-life operating robots, a similar process occurs: the software of the robot has to cope with the changes that happened in the body of the robot because of damaging events in its operational life. T…
The contribution of AI to enhance understanding of Cultural Heritage.
2013
The Artificial Intelligence & Cultural Heritage (AI & CH) working group was born in 1999 with the aim at promoting various scientific activities to increase a more active collaboration between the sectors of cultural assets and artificial intelligence. The many events (workshops and schools) organized over the years have shown the validity of this group for exchanging ideas and gathering researchers and practitioners from different fields. New applications of informatics and artificial intelligence have provided the opportunity to produce innovative tools for documenting, managing and communicating cultural heritage. For this anniversary we intend to show how some of the most important meth…
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…
CAMBIO DE ACTITUDES Y VALORES ANTE LA ENERGÍA TRAS EL USO DE UN JUEGO DE ROL
2010
Los juegos de rol en educación se han definido como dramatizaciones que se vertebran en torno a una situación concreta y utilizan la asignación de papeles a alumnos, quienes deberán defender con argumentos una opinión (previamente perfilada) frente a un problema. Cada vez más utilizados en la educación formal y no formal, destacan entre sus ventajas el convertir lo lúdico en aprendizaje, potenciar el aprendizaje de actitudes y valores y la conexión que se realiza con la vida real entre otros. La utilización de un juego de rol en una investigación educativa sobre cambio de actitudes y valores ante los recursos energéticos cuyos resultados educativos fueron positivos, permitió repetir dicha i…
Hacia la implementación de un modelo de atención temprana por parte de una Organización Paraguaya
2020
Implementation science has been developed to help understand why evidence-based practices are not adopted as rapidly as they might. We describe here the process a rehabilitation center in Paraguay is undergoing to transform itself into a state-of-the-art early intervention program. We describe the organization and its contextual strengths and barriers, the model it chose to implement, and the implementation procedures it has attempted. The implications for model fidelity are highlighted, as this organization needed to make adaptations to the model as designed, to fit the particular context of its mission and the Paraguayan culture. Features of the Routines-Based Model are described. La cie…
