The Urban Landscape in the Graphic Representation of the Cathedral of Palermo
2018
This study proposes some reflections on the relationship between the Cathedral of Palermo and the urban portion where it is placed, in relation to the indissoluble connection with the landscape that in the history offered a variety of perceptive suggestions marked by the passage and the coexistence of different cultural and social domination. To this end, the multiscale historical-urban planning analysis puts in place the role that territorial and urban morphology has had over time in relation to the Cathedral of Palermo. In this sense, the relationship between the architectural artefacts, such as the Royal Palace and the Town Hall, and the urban context is studied according to its access r…

The new boundaries of digitization: from bim to parametric modelling
2022
The theme of digitization and documentation, which inevitably affects the fields of surveying and designing architecture and urban areas, is constantly innovated by the new digital technologies and new multimedia communication systems that allow us to acquire, analyze and disseminate the value of our historical heritage. Research in this field pushes us to overcome the limits imposed by tested technologies in order to extend the field of application in the surveying and representation of the increasingly complex challenges imposed by the needs of conservation and maintenance. This volume, which follows on from the three previous conferences of the “Digital & Documentation” cycle that to…
Simultaneità e alterazione. Forme e immagini di luce in narrazione visuale
2018
Questo studio fornisce una modalità di lettura dell’immagine basata sul riconoscimento dei termini grafici relativi alla didattica dei Vchutemas e del Bauhaus: la struttura, la texture e la costruzione. L’obiettivo è quello di esplorare il disegno delle avanguardie artistiche attraverso uno spazio digitale tridimensionale restituendo nuove immagini prodotte dalla molteplicità dei punti di vista dei modelli (proiezioni ortogonali, assonometrie, esplosi). Si tratta di una narrazione grafica che dalla geometria delle forme si configura nelle ombre e nelle trasparenze dei volumi attraverso i materiali relativi al linguaggio visuale e alla rappresentazione dell’architettura. The article gives a …
Gustavo Pulitzer Finali. Interpretazioni grafiche di una Villa sul mare, 1930.
2017
Questo studio riguarda la lettura grafica di un progetto mai realizzato di Gustavo Pulitzer Finali, una ‘Villa sul mare’, presentato alla Triennale di Monza nel 1930. Il ridisegno del progetto, necessario per la comprensione del pensiero architettonico, mostra come l’architetto triestino sia riuscito a sintetizzare l’architettura navale e quella di terra in un unico organismo plastico. Il modello digitale, strumento di indagine di spazi, ad oggi, non esplorati, fornisce alla letteratura scientifica immagini inedite del progetto di Pulitzer Finali. This study concerns the graphic reading of an unbuilt project by Gustavo Pulitzer Finali, a ‘Villa by the sea’, presented at the Triennial in Mon…
Computational modelling of brittle failure in polycrystalline materials using cohesive-frictional grain-boundary elements
2014
A 3D grain-level formulation for the study of brittle failure in polycrystalline microstructures is presented. The microstructure is represented as a Voronoi tessellation and the boundary element method is used to model each crystal of the aggregate. The continuity of the aggregate is enforced through suitable conditions at the intergranular interfaces. The grain-boundary model takes into account the onset and evolution of damage by means of an irreversible linear cohesive law, able to address mixed-mode failure conditions. Upon interface failure, a non-linear frictional contact analysis is introduced for addressing the contact between micro-crack surfaces. An incremental-iterative algorith…
Dynamic Preisach hystersis model for magnetostrictive materials for energy application
2013
Recently Magnetostrictive materials have been proposed as active materials to be used in several energy harvesting technology [1]. In this kind of application, the working condition of the material is highly dynamic and non linear. As a result static models of magnetostrictive materials are usually not very accurate and can be not reliable to develop a sufficiently accurate designof the energy harvesting devices. The presence of hysteresis requires accurate mathematical modeling in order to correctly foresee the behavior of real materials (ferromagnetic or magnetostrictive) used in control systems or in electrical machines and thus simplifying the design of such controllers or predicting wi…
Dynamic simulation of a 4th Generation District Heating network with the presence of prosumers
2022
District Heating Network is identified as a promising technology for the decarbonization of urban areas. Thanks to the surplus of heat available from distributed renewable energy plants, a typical heat consumer of the network could become an energy producer during the day (typically referred to as “prosumer”). Models for thermal grids developed during the years usually assumed a centralized heat production. The increasing presence of prosumers will require accurate dynamic modeling to monitor the changes induced in the thermohydraulic variables of the network. To fill this knowledge gap, this paper aims at developing a model of a thermal grid with prosumers in TRNSYS environment. The model …
A Chemical Approach to the Modelling of Band Gap of Passive Films for Corrosion Studies
2015
Photocurrent Spectroscopy (PCS) has gained a large consideration in the last decades as in situ technique for the characterization of semiconductors and photoconducting passive film/electrolyte junctions being able to provide information on the location of characteristic energy levels like: flat band potential (Ufb), internal photoemission threshold (Eth) and band gap value (Eg)
