The aim of this contribution is to refresh my studies on Gaspare Beretta, published in the 90's. At the service of three kings, Philip IV, Charles II, Philip V, thanks to his memory of 1696 we know a lot about his life: from the first enrollment 1639-51, to his election as State's First Engineer in 1657, up to being designated as Engineer of Factories, from 1651 to 1703. The documents analyzed, which are often autograph, are locate in: Biblioteche Trivulziana e Ambrosiana, Civica Raccolta «Bertarelli», Archivi di Stato di Milano e Torino; Archivo General de Simancas, and Osterreichisches Staatsarchiv, Kriegsarchiv, Vienna. The accurate drawings, of great skill, often with captions, reveal a mature awareness in the theories and techniques of representation of cities, fortresses and territory, especially when compared to the previous generation. The new grammar of the bastioned front is characterized by bulwarks of larger sizes, multiple levels of artillery in casemates and open pit, greater use of advanced works - ravelins, crescents, counterguards, lunettes, arrows, batten - with ditches, covered roads and feasting divided by gabions, paradoxes, bearers stands, with border squares, hub, supportive. The drawings will be cross evaluated with various documents and compared with drawing schools, geometry and military strategies. Beretta, therefore, has a strong profile in European defense context. If the predecessors are Baldovino, Prestino e Richino, his collaborators Formenti, Sesti, Joseph Chafrion Serena, the new masters - strangers to Italy - Pagan, Vauban, Frenchs; van Rusensteen, van Coehoorn, Storf de Belleville, Dutch; de Verboom, Flemish.

The share of distributed energy generation is growing at a rapid pace. The dropping cost of photovoltaic panels and Governments' incentives are making more and more convenient the installation of photovoltaic panels for privates all around the world. In this thesis, data from 18 houses in the Netherlands is collected and analyzed to verify the effect of a large concentration of photovoltaic energy generation on the distribution grid. The study reveals that during Spring and Summer problems for the grid may arise due to the large amount of current injected into the grid. Distributed storage, through the installation of batteries, and load shifting are simulated to test their effectiveness in the reduction of the over-injection problem. The results of the physical model are then studied from the economic perspective to verify which option is the most profitable. Finally, different machine learning algorithms are implemented to predict the load consumption and photovoltaic energy generation one-day ahead.
