EUROPA 2020 IN SICILIA: SPIN-OFF DI RICERCA, DISTRETTI HIGH-TECH E STRATEGIE DI INNOVAZIONE ISTITUZIONALE
2014
Gli indicatori di posizione che quantificano le priorità della strategia Europa 2020 denunciano un ritardo nello sviluppo della Sicilia rispetto alle altre regioni italiane. Per ridurre tali divari si propongono strategie trainate dall`innovazione quali ad esempio distretti tecnologici e spin-off di ricerca. Dopo un excursus di letteratura volto a mettere a confronto queste due forme di innovazione tecnologica ed organizzativa, viene proposto un esercizio empirico che intende verificare quanto la creazione di imprenditorialità da parte dell’Università può contribuire alla riduzione dei divari di sviluppo. Si intende proporre alcune suggerimenti di policy per aumentare la loro efficacia nell…
A Critical Comparison of Remote Sensing Leaf Area Index Estimates over Rice-Cultivated Areas: From Sentinel-2 and Landsat-7/8 to MODIS, GEOV1 and EUM…
2018
Leaf area index (LAI) is a key biophysical variable fundamental in natural vegetation and agricultural land monitoring and modelling studies. This paper is aimed at comparing, validating and discussing different LAI satellite products from operational services and customized solution based on innovative Earth Observation (EO) data such as Landsat-7/8 and Sentinel-2A. The comparison was performed to assess overall quality of LAI estimates for rice, as a fundamental input of different scale (regional to local) operational crop monitoring systems such as the ones developed during the "An Earth obseRvation Model based RicE information Service" (ERMES) project. We adopted a multiscale approach f…

Presentazione
2011
In questa presentazione, è sintetizzata la versione rivista e ampliata degli interventi svolti dai relatori nel convegno intitolato "Cinematografia ed Educazione Interculturale: una finestra aperta verso il dialogo" realizzatosi il 23 marzo 2011. Questo Convegno è stato organizzato dai docenti afferenti al corso di laurea in Scienze dell'Educazione della Facoltà di Psicologia e Scienze della Formazione dell'Università "Kore" di Enna. In this presentation, the revised and expanded version of the interventions carried out by the rapporteurs in the conference on 23 March 2011 titled “Cinematography and Intercultural Education: a window open to the dialogue” is synthesized. This conference has …
La consegna educativa
2021
Una rilettura critica del saggio “La consegna”, di Antonio Bellingreri. La riflessione, di pedagogia fondamentale e filosofia dell’educazione, è volta ad indagare i tratti costitutivi, ovvero l’essenza, della persona umana, a partire da un’analisi dell’epoca contemporanea, restituitaci dalla letteratura come tardo-moderna. Di una gioventù privata di significativi modelli di comportamento e sistemi valoriali, diffidente del passato non meno che del futuro, intende farsi carico l’educazione, privilegiato strumento per re-immettere in circolo valori e significati smarriti. Divenendo consegna, la relazione educativa risponde al bisogno posto al fondo della persona umana (il bisogno di riconosci…
A polynomial algorithm solving a special class of hybrid optimal control problems
2006
Hybrid optimal control problems are, in general, difficult to solve. A current research goal is to isolate those problems that lead to tractable solutions [5]. In this paper, we identify a special class of hybrid optimal control problems which are easy to solve. We do this by using a paradigm borrowed from the Operations Research field. As main result, we present a solution algorithm that converges to the exact solution in polynomial time. Our approach consists in approximating the hybrid optimal control problem via an integer-linear programming reformulation. The integer-linear programming problem is a Set-covering one with a totally unimodular constraint matrix and therefore solving the S…
A robust calibration methodology for an On-Board Diagnostic car system
2006
New car models are now by law equipped with on-board diagnostic (OBD) systems aimed at monitoring the state of health of strategic components that ensure low levels of polluting exhaust emissions. During development phases, for each new car model, the OBD system must be finely calibrated. This article presents a robust calibration methodology taking into account sources of variability mainly due to production process, operating, and environmental conditions. The methodology enables us to evaluate the false alarm and failure to detect risks intrinsically related to the adopted calibration. An application concerning an upstream oxygen sensor monitored by the OBD is presented.
Decentralized Synchronization for Zigbee wireless sensor networks in Multi-Hop Topology
2010
Abstract The most effective solution for energy saving in low-rate wireless sensor networks is maintaining each node in a doze state as long as possible. In order to guarantee network connectivity, the intervals at which the network sensors are turned on and off have to be coordinated. We analyze the Zigbee MAC performance in sensor networks deployed in multi-hop topologies. For this networks, critical inefficiencies can arise due to transmissions performed by hidden nodes. We evaluate the impact of different synchronization schemes on the network performance, both in terms of network capacity and in terms of energy consumption. We show how the synchronization function can be opportunistica…
Monitoring of the effect of solar radiation and rain on the building envelope with integrated vertical vegetation
2022
The goal of the present paper is the verification of the improvement of the performance of a building envelope with a green wall also in conditions of high irradiance (≥0.6 kW/m2) and with variable meteorological conditions (sunny, cloudy, and rainy), with a focus on intense rainfall and tempest. The object of the analysis has been the Innovation and Technology for Development Center in the University Campus of the Polytechnics of Madrid, where a modular system of integrated vertical vegetation has been installed on the skin of the South and West prospects. The study is based on the analysis of the effective thermoregulation capacity of the system in different climatic situations and has be…
