BioAnalysis: A Framework for Structural and Functional Robustness Analysis of Metabolic Networks
2010
The main objective of this work is to analyze metabolic networks evolution in terms of their robustness and fault tolerance capabilities. In metabolic networks, errors can be seen as random removal of network nodes, while attacks are high-connectivity-degree node deletion aimed at compromising network activity. This paper proposes a software framework, namely BioAnalysis, used to test the robustness and the fault tolerance capabilities of real metabolic networks, when mutations and node deletions affect the network structure. The performed simulations are related to the central metabolic network of the well-known E. coli single-celled bacterium and involve either hub nodes or non-hub nodes,…
Fixed-size Quadruples for a New, Hardware-Oriented Representation of the 4D Clifford Algebra
2010
Clifford algebra (geometric algebra) offers a natural and intuitive way to model geometry in fields as robotics, machine vision and computer graphics. This paper proposes a new representation based on fixed-size elements (quadruples) of 4D Clifford algebra and demonstrates that this choice leads to an algorithmic simplification which in turn leads to a simpler and more compact hardware implementation of the algebraic operations. In order to prove the advantages of the new, quadruple-based representation over the classical representation based on homogeneous elements, a coprocessing core supporting the new fixed-size Clifford operands, namely Quad-CliffoSor (Quadruple-based Clifford coproces…
Piecewise planar underwater mosaicing
2015
A commonly ignored problem in planar mosaics, yet often present in practice, is the selection of a reference homography reprojection frame where to attach the successive image frames of the mosaic. A bad choice for the reference frame can lead to severe distortions in the mosaic and can degenerate in incorrect configurations after some sequential frame concatenations. This problem is accentuated in uncontrolled underwater acquisition setups as those provided by AUVs or ROVs due to both the noisy trajectory of the acquisition vehicle — with roll and pitch shakes — and to the non-flat nature of the seabed which tends to break the planarity assumption implicit in the mosaic construction. These…
L'avvertenza sull'inadeguatezza dell'operazione di investimento e i rimedi a tutela del risparmiatore
2016
Il commento analizza la sentenza della Corte di Cassazione che, in ragione dell’inadempimento da parte dell’intermediario finanziario del dovere di informazione completa e corretta sull’inadeguatezza dell’operazione di investimento, ha pronunziato la risoluzione del contratto di compravendita dei titoli di debito dello Stato argentino intercorso tra cliente e banca. Mossi una serie di rilievi critici, nel metodo e nel merito, alla esegesi operata dalla Supr. Corte, si propongono gli argomenti a sostegno di una diversa lettura dell’art. 29 reg. intermediari n. 11522/1998, in tema di ‘‘operazioni non adeguate’’, specie in punto di ricadute nella individuazione dei rimedi più appropriati alla …
Norma ed azione nell'internazionalizzazione del territorio
2008
Pensare ed operare in prospettiva d’azione internazionale è un’esigenza concreta oggi ineludibile tra comunità e aree locali, per chiunque voglia operare in maniera opportuna in un mondo sempre più aperto ed in cambiamento. Nasce la necessità di “internazionalizzare” il proprio territorio, che non significa annullare o omologare le peculiarità territoriali, ma, visto nella sua complessità, tale processo è un fenomeno multidimensionale e pluridirezionale che, pertanto, è difficile possa riguardare solo alcuni ambiti della vita di una collettività. L’internazionalizzazione del territorio è una materia investita dal processo di decentramento amministrativo, ma, in attesa della concreta definiz…
Il Patto sulle migrazioni e l’asilo della Commissione europea del 23 settembre 2020 e il dovere di soccorso in mare
2021
The pact on asylum and migration, presented by the European Commission on 23 September 2020, addresses some of the problems related to search and rescue operations and the following disembarkations. The present paper is skeptical about the real capacity of the pact to reduce the existing tensions among Member States in this field; it also underlines the ambiguities of the pact concerning Member States’ cooperation with NGOs engaged in SAR activities
Archeologia e scenografia nel teatro musicale del primo Ottocento: le immagini di Roma antica
2010
Le consuetudini più in voga nella rievocazione del mondo antico nell’opera lirica italiana del XIX secolo sono rivelate dai bozzetti conservati delle scenografie. In questo lavoro sono analizzate in particolare scenografie raffiguranti vedute di Roma antica.
The Eighteenth-century Opera and the Search for a Meeting Point between Music and Declamation
2019
The article is the result of some researches about the ideas on the operatic reform appeared in Italy and France from 1740s onwards. On the basis of acting, some treatises written by actors, philosophers and musicographers claim the dramatic superiority of recitativo secco or obbligato, and the beauty of aria parlante. (e.g., L. Riccoboni, Dell’arte rappresentativa, 1728, G. Manfredi, L’attore in scena, 1734, G. R. Carli, L’indole del teatro tragico, 1746, and Osservazioni sulla musica antica e moderna, 1744-1786, G. Tartini, Trattato di musica secondo la vera scienza dell’armonia, 1754, F. Algarotti, Saggio sopra l’opera in musica, 1755). Owing to its particular speaking tone linked to dec…
La 'riforma' a Napoli: materiali per un capitolo di storia della ricezione
2009
From 1774 to 1785, Naples hosted six different productions of Gluck's 'reform' operas: two of "Orfeo ed Euridice" (both in 1774, but in two different versions and venues), two of "Alceste" (in 1779 and 1785) and two of "Paride ed Elena" (in 1777 and 1779). In the first part, the article collects and discusses all the extant documents about these performances. The second part is a detailed study of the ideas of the Neapolitan theorists about Calzabigi and Gluck. The article demostrates that, even if some authors appreciated specific features of the 'reform', the Neapolitan musical culture was dominated by a more traditional operatic taste.
The Italian “National Opera” Imagined from a Southern Slavic Viewpoint: Franjo Ks. Kuhač and Josip Mandić
2019
The national awakening after the revolutions of 1848, and the related phenomenon of new operatic grammar disseminated from Russia and Bohemia to other countries of Central Europe, were the main factors in promoting a quest of musical autonomy either in Slovenia or in Croatia. In the light of the Southern Slavic people revival, the criticisms on the Italian opera and the Wagnerian Musikdrama, written by the prominent musicologist Franjo Kuhač (1834-1911), and the composer Josip Mandić (1883-1959), reveal two parallel points of view, which have not been taken into account until today. The negative judgement of Kuhač on the last works of Verdi, influenced by Wagner formulae, and the praise of …
