A Posture Sequence Learning System for an Anthropomorphic Robotic Hand

2003

The paper presents a cognitive architecture for posture learning of an anthropomorphic robotic hand. Our approach is aimed to allow the robotic system to perform complex perceptual operations, to interact with an human user and to integrate the perceptions by a cognitive representation of the scene and the observed actions. The anthropomorphic robotic hand imitates the gestures acquired by the vision system in order to learn meaningful movements, to build its knowledge by different conceptual spaces and to perform complex interaction with the human operator.

La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo

2023

Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…

Within this framework Palermo and its historic center are no exception. The epicenter of these processes is represented here by the Kalsa district which since the early 2000s has been placed at the center of a precise strategy of culturally-based renewal called to drive the city's tourist renaissance (Vinci 2008). The culmination of this path came in 2018 when Palermo was named the Italian capital of culture and chosen as the venue for Manifesta one of the most prestigious traveling biennales of contemporary art. However the exponential increase in tourist arrivals in the last three years came to a halt with the outbreak of the pandemic which showed with unprecedented evidence the contradictions of the development strategies pursued in the historic center and the marks they leave on the territories. While this sudden interruption seems to offer an opportunity to radically rethink urban and cultural policies and find new curbs to the conditions of overtourism in which the historic centers of South European cities and beyond find themselves it could also prove to be an accelerator of the dynamics of commodification of these spaces representing the revival of tourism an easy escape route in times of crisis. The objective of this contribution is to critically explore the urban and social transformations that have crossed the Kalsa district of Palermo from the 2000s to the present using qualitative and quantitative techniques (analysis of statistical data in-depth interviews critical discourse analysis ...) with particular reference to the role that culture has played in these processes. While it is impossible to prefigure post-pandemic scenarios we will examine documents and discourses that trace possible development directions for South European cities and their historic centers.Settore ICAR/21 - UrbanisticaSettore M-GGR/01 - Geografia

Topological Hopf algebras, quantum groups and deformation quantization

2003

After a presentation of the context and a brief reminder of deformation quantization, we indicate how the introduction of natural topological vector space topologies on Hopf algebras associated with Poisson Lie groups, Lie bialgebras and their doubles explains their dualities and provides a comprehensive framework. Relations with deformation quantization and applications to the deformation quantization of symmetric spaces are described

The Urban Exposome during Pregnancy and Its Socioeconomic Determinants

2018

Background: The urban exposome is the set of environmental factors that are experienced in the outdoor urban environment and that may influence child development. Objective: The authors’ goal was to describe the urban exposome among European pregnant women and understand its socioeconomic determinants. Methods: Using geographic information systems, remote sensing and spatio-temporal modeling we estimated exposure during pregnancy to 28 environmental indicators in almost 30,000 women from six population-based birth cohorts, in nine urban areas from across Europe. Exposures included meteorological factors, air pollutants, traffic noise, traffic indicators, natural space, the built environment…

Un modèle radiocentrique pour l'analyse des espaces ruraux périurbains

1995

Research on periurbanisation’s factors, a phenomenon that has greatly contributed to the demographic growth of French rural areas for the last twenty-five years, leads us to ask about the determinants of residential location in rural areas of people working in a town. In order to answer this question, it is necessary to transpose residential location models usually used at the scale of the town - models which are the basis of the New Urban Economics school - to periurban areas. The area we are interested in is differentiated both from urban and rural areas seen from the agricultural production point of view. But we show that it can be analyzed in the same manner as urban areas. However, thi…

Economies d'agglomération et configurations spatiales dans les espaces ruraux

1997

The question to be addressed here is that of the agglomeration/dispersion forces that are likely to account for the location of people and jobs in rural areas and the way they explain spatial patterns in rural areas depending on urban influence. Economic geography models may provide suitable tools with which to investigate the organization of rural areas. We first review these models, focusing on dispersion forces, which rest basically on land consumption and transport costs. We suggest then a set of hypotheses concerning the main forces at work in rural areas. Intensity of agglomeration economies is hypothesized to be related to the urban size, which in turn induces increasing land rents a…

Characterization of the metal artefacts of the two craft-quarters of the roman vicus Bliesbruck (Moselle)

2014

Diese Arbeit ist ein vollständiges Studium der Metallfunde aus den zwei Handwerkervierteln von Bliesbruck (Moselle, Frankreich). Diese Funde stammen aus vierzigjahrelangen Ausgrabungen. Das Korpus besteht aus 450 Kg Metall (Eisen, Kupferlegierungen, weisse Metalle, Gold) wovon 4 200 Objekte und 22 000 Nägel. Eine Objekt- und Funktionsidentifizierung und eine typologische Nägelzahl haben es ermöglicht, die Objektverbindungen wieder zusammenzusetzen und die Daten nach verschiedenen Kriterien einander gegenüberzustellen : Metall, Lage (Viertel und Grundstück), Chronologie und Befundnummertyp. Diese Datenüberfülle und -verschiedenheit ermöglichen das Korpus nach vielartigen geographischen Maβst…
