No full textPhotovoltaic (PV) plants in Italy are presently subject to a rapid increase due to recent government incentives dedicated to grid connected PV plants. Incentives are given on the basis of the energy actually delivered to the grid, so that it becomes fundamental for the owner to produce as much energy as possible in order to reduce the payback time. In this framework, PV system efficiency plays a fundamental role. This paper focuses on medium and large size PV power systems, for which plant efficiency becomes a key design issue. In particular, the choice between centralized or distributed ("string") architecture is analyzed in terms of plant efficiency, considering the following basic issues: (1) losses in the power electronic conditioning system; (2) losses due to cable dissipation; (3) losses due to possible maximum power point mismatch
The Photovoltaic Laboratory at the University of Trieste, Italy
No full textThis work deals with the description of the Photovoltaic Laboratory at the Department of Engineering and Architecture of the University of Trieste. The description of the main facilities involved, such as three grid-connected photovoltaic plants and a test facility for the characterization of photovoltaic modules, is being proposed. Moreover, an overview of the recent and future research activities is given
Il contributo di Sergio Torsello alla renaissance salentina del primo quindicennio del 2000
No full textQuesto contributo mira a descrivere le tre “anime” di Sergio Torsello – Direttore Artistico del Festival La Notte della Taranta, Consulente Scientifico dell’Istituto Diego Carpitella, e Mediatore Culturale tra e per i talenti artistici del suo territorio. Il punto di partenza della narrazione è un articolo di Sergio Torsello, pubblicato nel 2011 in un volume di cui l’autore della narrazione è stato curatore. L’autore sottolinea la stretta connessione tra le tre anime di Sergio Torsello, che emerge non solo dal suo articolo del 2011 ma anche dalle numerose interazioni avvenute tra Sergio Torsello e l’autore. La descrizione del rilievo scientifico della figura di Sergio Torsello è sicuramente parziale, circoscritta nel tempo (gli 8 anni, dal 2007 al 2015 in cui ha interagito con l’autore) e nello spazio (inteso come insieme di argomenti delle loro conversazioni scientifiche e culturali). Ma rende merito del cruciale contributo di Sergio Torsello alla renaissance culturale salentina degli anni dal 2001 al 2015.This contribution aims to describe the three “souls” of Sergio Torsello – Artistic Director of “La Notte della Taranta” Festival, Scientific Consultant of “Diego Carpitella” Institute, and Cultural Mediator
between and for the artistic talents of his territory. The starting point of the description is an article by Sergio Torsello, published in 2011 in a book of which the author of the description was the editor. The author highlights the close connection between the three souls of Sergio Torsello, which emerges not only from the above-mentioned article, but also from the numerous interactions between Sergio Torsello and the author. The description of the scientific significance of Sergio Torsello’s figure is certainly partial, limited in time (the 8 years, from 2007 to 2015, in which he interacted with the author) and in space (in terms of set of topics of their scientific and cultural conversations). But it gives merit to Sergio Torsello’s key contribution to the cultural renaissance of Salento in the years from 2001 to 2015
Stochastic Generalized Nash Equilibrium-Seeking in Merely Monotone Games
No full textWe solve the stochastic generalized Nash equilibrium (SGNE) problem in merely monotone games with expected value cost functions. Specifically, we present the first distributed SGNE-seeking algorithm for monotone games that require one proximal computation (e.g., one projection step) and one pseudogradient evaluation per iteration. Our main contribution is to extend the relaxed forward–backward operator splitting by the Malitsky (Mathematical Programming, 2019) to the stochastic case and in turn to show almost sure convergence to an SGNE when the expected value of the pseudogradient is approximated by the average over a number of random samples.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Sergio GrammaticoTeam Bart De Schutte
Sergio Bettini e la critica d’arte
No full textOn the occasion of the publication of two books about Sergio Bettini’s works (unpublished studies, conference proceedings and critical apparatus) the author analyzes the scientific production of this scholar during his life (1930-1986). Furtherly this essay analyzes the great scholar’s relationship with the School of Wien and first of all his deep connection with all European different critical and comparative points of view
