Cultural Heritage As A Driver Of Development
2010
After drawing attention to the importance of cultural heritage, the Authors analyze the inherent problems of the various stages: conservation, valorization and fruition which, interacting and fully respecting the integrity and identity of the asset and its history, can promote local economic development and employment opportunities.
Noncooperative dynamic games for inventory applications: A consensus approach
2008
We focus on a finite horizon noncooperative dynamic game where the stage cost of a single player associated to a decision is a monotonically nonincreasing function of the total number of players making the same decision. For the single-stage version of the game, we characterize Nash equilibria and derive a consensus protocol that makes the players converge to the unique Pareto optimal Nash equilibrium. Such an equilibrium guarantees the interests of the players and is also social optimal in the set of Nash equilibria. For the multi-stage version of the game, we present an algorithm that converges to Nash equilibria, unfortunately not necessarily Pareto optimal. The algorithm returns a seque…
The thermophysical characterization of technical elements in the historic architecture: experiences in Palermo
2014
Per contemperare il miglioramento delle prestazioni energetiche e ambientali dell'architettura storica con l'esigenza della sua conservazione, è necessario analizzare le caratteristiche termofisiche dei materiali e degli elementi tecnici che la connotano. Tuttavia la disponibilità di pochi dati in merito si somma alle disomogeneità tipiche della costruzione storica e alle difficoltà di analisi ad esse connesse. In particolare, per la trasmittanza termica delle murature storiche, la letteratura scientifica evidenzia scostamenti anche notevoli tra i valori desunti da misure in situ e quelli calcolati, in genere superiori ai primi. Il contributo espone gli obiettivi e la metodologia di un prog…
Introduction to coronary imaging with 64-slice computed tomography
2005
The aim of this article is to illustrate the main technical improvements in the last generation of 64-row CT scanners and the possible applications in coronary angiography. In particular, we describe the new physical components (X-ray tube-detectors system) and the general scan and reconstruction parameters. We then define the scan protocols for coronary angiography with the new generation of 64-row CT scanners to enable radiologists to perform a CT study on the basis of the diagnostic possibilities.
How should vaccination services be planned, organized, and managed? Results from a survey on the Italian vaccination services
2019
Background. Quality improvement is an increasingly recognized approach to maximize service effectiveness and minimize costs in public health. However, the Italian law never provided for the institutional accreditation of vaccination services. Furthermore, a recently approved law added six more compulsory vaccinations to the original four, which has led to a considerable increase in vaccination efforts, without any previous resources evaluation. The aim of the study was to investigate structural, organizational and managerial characteristics of the Italian vaccination services, in order to suggest the adoption of adequate quality standards. Study design. A survey involving the representative…
Josephson Traveling Wave Parametric Amplifiers as Non-Classical Light Source for Microwave Quantum Illumination
2021
Abstract Detection of low-reflectivity objects can be enriched via the so-called quantum illumination procedure. In order that this quantum procedure outperforms classical detection protocols, entangled states of microwave radiation are initially required. In this paper, we discuss the role of Josephson Traveling Wave Parametric Amplifiers (JTWPAs), based on circuit-QED components, as suitable sources of a two-mode squeezed vacuum state, a special signal-idler entangled state. The obtained wide bandwidth makes the JTWPA an ideal candidate for generating quantum radiation in quantum metrology and information processing applications.

The role of perceived value and emotions in the satisfaction and future intentions of spectators
2016
The quality of service offered by sports entities has become a good predictor of user satisfaction and also future intentions. To know the future intentions of customers of any service is a key objective to develop service improvement and retention strategies. This need has also become apparent to professional sports clubs. In this study, the relationship between quality, perceived value, emotions, satisfaction and future intentions of spectators are analyzed for a sporting event. Using a sample of 563 spectators and modeling with structural equations, results indicate that perceived value is the best predictor of the satisfaction and future intentions of spectators, while quality and emoti…
Performance improvement of a Savonius water rotor with novel blade shapes
2021
Abstract Savonius water rotor is a prominent drag based turbine able to extract energy available in flowing water with low velocity like river streams, tidal currents or other man made water canals. However, in view of its low performance, an enhanced design of the rotor blades is necessary to better its efficiency. Therefore, the present study aims to improve the efficiency of Savonius rotor by changing the blade design. Different blade shapes were investigated numerically using computational fluid dynamics (CFD). Using conventional design, the peak power coefficient was found to be 0.166 at tip-speed ratio of 0.78. However, the peak power coefficient reaches 0.184 using the optimal blade …
Network Dynamics of an Energy Supply Chain: Applicability of the Network Approach to Analysing the Industrial Ecology Practices of Companies
2006
Currently firms face environmental challenges, which require more emphasis on inter-organisational environmental improvement efforts. A field of study of industrial ecology offers some novel approaches for inter-organisational environmental management. It emphasises symbiotic linkages between firms or other organisations in which waste of one actor is used as raw material by others. The industrial network approach has been suggested as a possible framework for developing managerial implications for industrial ecology. This study analyses an example of an industrial ecosystem with notions of the network theory, and concludes that the industrial network approach is useful in analysing and des…
