Portraits of Leonardo da Vinci
No full textUsing an iterative method, applied to image processing, a portrait of a young man, probably a self-portrait of Leonardo da Vinci, is restored. Merging this portrait with the self-portrait in red chalk, we can have the features of a middle-aged Leonardo. This digital portrait can be compared with the image of Plato, depicted by Raphael in the Scuola di Atene, generally considered as a portrait of Leonardo. The iterative method used for the image processing had been developed by the author on previous iterative calculations used to solve the Boltzmann equatio

Why (and how) to regulate Power Exchanges in the EU market integration context?
No full textPower Exchanges (PXs) are key market institutions in open and market-based electricity industries. This paper aims at contributing to the ongoing debate on why and how to regulate Power Exchanges in the EU market integration context. . The paper starts by stating that two different types of PXs have to be distinguished, i.e. "Merchant" PXs and the "Cost of Service Regulated" PXs. The paper continues by comparing the typical incentives of these two types of PXs to perform the basic PX tasks in an isolated national market and in a market integration context. The paper concludes by deriving from this analytical frame the most relevant regulatory actions..Regulation, Exchanges, Grid access, Power Markets.
La Roma di Mussolini: una costruzione del cinema
No full textThe paper offer to the readers the treatment and the text the author prepared to realize the documentary film, La Roma di Mussolini, produced in 2003 by the Istituto Luce. It opens with a discussion of fascist newsreels and their relationship with the public. Then in an examination of the entire production of the period, the author propose the thesis that fascist newsreels on the items of modernization of city have had in Italy a similar rule than in the rest of Europe: the building of a new social and urban culture.

Recensione dell'articolo: (Miyazawa, Masakiyo - " Light tail asymptotics in multidimensional reflecting processes for queueing network " - TOP 19 (2011), no.2, 233–299.)
No full textIn this paper the author studies the stationary distribution of a class of discrete time reflecting processes which are defined on a multidimensional nonnegative space. The focus is on studying performance evaluation of queuing network models subject to specific conditions such as the so-called heavy traffic condition. In this context the author also offers a wide overview that describes the current approaches. Leonardo Pasin
Recensione dell'articolo:(Barron, Yonit - "A threshold policy in a Markov-modulated production system with server vacation: the case of continuous and batch supplies." Adv. in Appl. Probab. 50 (2018), no. 4, 1246-274.) MR3881118 MathSciNet ISSN 2167-5163
No full textIn this paper, the author defines a production-inventory fluid model with an in-
nite buffer, where the inputs and outputs are controlled by a background irreducible
continuous-time Markov chain representing the environment. As soon as the fluid in the
storage reaches level zero, the machine becomes idle until the total fluid exceeds level
D with D > 0. The author assumes that switches from idle periods and busy periods
take no time and studies two separate types of models with different supply process patterns:
fluid-type models and Markov additive process-type models. Leonardo Pasin
