Integrazione dei dati acquisiti con sistemi image-based e range-based per una rappresentazione 3D efficiente
No full textLe tecnologie digitali hanno rappresentato un’occasione di innovazione e sviluppo in ambito rappre-sentativo durante i mesi di pandemia quando la comunicazione scientifica si è forzatamente costretta nei canali di comunicazione digitale.
Il rilievo digitale, con l’integrazione di tecniche image-based e range-based consente di ottimizzare le misure sviluppate sul modello 3D e le relative rappresentazioni in ambito tecnico. Questo studio presenta l’analisi di una pipeline innovativa per integrare un dataset laser scanner direttamente all’in-terno della pipeline fotogrammetrica in un unico ambiente software. L’obiettivo principale è testare diverse procedure per l’allineamento e l’integrazione di nuvole di punti da sensori attivi (Terristrial Laser Scanner) e passivi (Fotogrammetria close-range). In particolare, sono state analizzati tre approcci: scala e roto-traslazione con Ground Control Point sfruttando il self-calibration bundle adjustment foto-grammetrico; integrazione dei panorami sferici delle singole stazioni laser nel flusso fotogrammetrico; script in Python per allineare la nuvola densa fotogrammetrica nel sistema di riferimento del TLS con una procedura ICP (Iterative Closest Point).
Lo studio presenta i primi risultati ottenuti per un caso studio a scala architettonica: il Mulino del Can-tone, lungo il fiume Lambro nel Parco di Monza (MB). L’approccio integrato apre nuove opportunità per realizzare un rilievo 3D efficiente e una rappresentazione grafica completa
Arco Felice Vecchio, Cuma, Italia
No full text"Among them Euboici mountains in the middle of a narrow valley, Is there erected a majestic monument called Arco Felice, beneath which ran the Via Domiziana, branch of the Via Appia, which even now there are observed leftovers in the long clips from whence Mondragone stretched unto Cuma. Cuma then branching out from one side came in Baja, and on the other side passing under Arco Felice came in Pozzuoli, as mentioned above. Good portion of this road was built where Domitiana the forest of Ami was cut by Agrippa". In Campania the ancient Via Appia did not crossed or lapped the shoreline of the city and did not reach Cuma, therefore, the maritime colonies, increasing their importance commercial and military more and more, imposed a link to the Appia towns along the coast, passing through Cuma and finally arrive at Puteoli and then to Naples. This connection, willed by the emperor Domitiano to shorten the communication between Rome and the ports of Pozzuoli and Miseno, avoided the long detour imposed by Appia, which from Sinuessa penetrated into the interior of Capua, and then the Via Campana, from Capua to Pozzuoli. The work was realized in a short time and present a new way of communication later called "Via Domitiana". Overcoming issues was achieved depending on the case, or with deep vertical incisions performed by cutting the hill or through tunnels ( Cryptae ) carved into the rock, depending on the orography and the texture of the soil. Among the most significant works of this type may include the cut made along the Via Campana, at the Montagna Spaccata near Quarto to connect Pozzuoli and Capua, and the opening of the tunnel called Grotta di Cocceio, from the name of the manufacturer, which put in communication port Iulius across the lake Averno, with Cuma passing mount Grillo and yet the crypta Neapolitana and the Grotta di Seiano in Posilippo, located between the Gaiola and Coroglio. These interventions were carried out considerable technical difficulties to allow the passage of a new road, straight as much as possible, in a region characterized by rugged extremely irregular due to the presence of volcanic craters in the Campi Flegrei. To allow the passage of the road Domitiana through the mountain Grillo, was made an arch called Arco Felice, road engineering work performed by the Roman builders. For its implementation was extended a passage in the mountain probably already existed in Greek period, through a cut high and tight, then defining a deep section, at the same time, the same built a majestic arch on the pass, topped with other arches clad structure cementicia brick.
The work has so varied justifications: to ensure communication between the two sections of the ridge and at the same time, counter pressures, in order to prevent landslides from the flanks of the mountain, intensively cultivated since ancient times, as well as, represent the monumental entrance to the city of Cuma along the eastern side. However, contrary to what was believed, no trace of the aqueduct can be seen above the arches and along the edge of the hillside. The Arco Felice was built in 95 A.D. in the place where maybe was already opened in Greek, in a higher position, the door of the walls of Cuma. It originally was built in brickwork and tiled in marble, surmounted by two rows of arches lighter in texture cementicia covered with brick. Its piers had, on both sides, three niches where statues were placed. As reported in Palatine "There are niches adorned with others at the top, so it seemed to Capaccio, then even the Father Paoli, above which there was raised the Temple of Apollo Cumano : but, however, on the arch there is not be space to have been a temple, and even observes that there is no vestige monument". The Arco Felice as it can be seen from the graphs of survey, consists of a fornix of length m 17.65, width m 6.30 and height in m key. 17.50 surmounted by arches that reach a total height of m 32.00 the share of the paving of the ancient Via Domitiana. The walls of the monument are made of masonry curtain of tuff stones blocks the size of 25-30 cm wide, 8 cm to 9 cm in height and depth. The barrel vault that covers the lower fornix is made of square bricks called bipedales measurement of 59 cm from the side arranged radially, according to three rows of concentric arches to all sixth. Once the central arch, located immediately above the lower fornix, presents, in the facade toward Pozzuoli, an arch shot with a single row of bipedales. The walls erected on the sides of the arch for the containment of the soil are made of mixed masonry, consisting of regular appeals tufelli, interspersed, at a distance of about 1.20 m, curbs chaining performed with rows of bricks on the length of 25-30 cm and a top row of bipedales. The arch rests on a base of blocks piperno aligned, which measure each m 0.85 x 0.85 and protrude from 0.85 m from the walls of the arch, reducing the road to about m 4.50. The base probably served as protection in transit pedestrian sidewalks. The paving of the original Roman road, the old road Domitiana through the arch, is sufficiently intact and in good condition. Of this roadway, paved and lined with treatment still wayside stone, arranged alternately along the sidewalks, there are some features in sight. Examples are visible in Cuma at Masseria Poerio and, later, as beyond the casino Licola.
More news can be inferred from a reading of former reliefs, as the structural scheme adopted and the manner of performance of the construction of the building.
The facade toward Cuma, above the central arch, a single row of arches, the central one, lacking the time today collapsed, is wider than the lateral and presents, with respect to them, the walking surface to a lower altitude. All three arches are, however, aligned to the height of the keystone, evidently for the need to allow the original road link between the two ridges hilly interrupted. The statement potioned toward Pozzuoli reveals, however, a structural diagram substantially different. The arches above the central arch are, in fact, made on two orders.
Some news about the probable changes made may be revealed by the views of the travelers of the eighteenth century and played in numerous guides on the antiquities of the Campi Flegrei. This refers in particular to the views reproduced in Avanzi delle antichità esistenti a Pozzuoli, Cuma e Baja, by Antonio Paoli, published in Naples in 1768 where the arch is seen coming from Cuma and on the of a lithograph by Philippe Benoist, where the arch is seen coming from Pozzuoli. Therefore, it is evident that the structure lost the series of niches, having had over the centuries a long series of changes that have profoundly changed the original appearance of the arch, as the loss of the marble cladding, the closure of the upper arches walled up in the first half of the eighteenth century, the variation of the eastern facade, which completely has been restored during the last decade of the eighteenth century. Structure of the original Roman remains only inside and part of the western facade.
"Beyond the Arco Felice covers the suburbs of Cuma: remains of tombs and Roman villas lining the road to the foot of the hill of rock on which alone, in view of the sea and a long stretch of sandy beach, rises the acropolis of Cumae"
Complex composite technology investigation: Simulations and experimental results
No full textThe paper deals with discussion of research activities within ITEMB (InTEgrated Full Composite Main landing gear Bay Concept) framework, an EU Clean Sky 2 program coordinated by Airbus. The driving motivation for the investigation on such a technology was found in the opportunity to design a main landing gear bay in a full composite configuration: Rational approaches have been implemented in an efficient testing stage providing the necessary database for the static qualification of the conceived design. Advanced and innovative solutions for a "more integrated" system were duly analysed and experimentally validated thus proving the overall device compliance with industrial standards and applicable airworthiness requirements

Design and prototyping of a novel composite architecture for a widebody landing gear bay
No full textComposite materials may reduce the final weight of the aircraft structural components, in addition to improve fatigue performance and corrosion resistance. In order to achieve the optimization of air transport systems, making them increasingly sustainable, the structural design must be surely reviewed, starting to follow the "composite thinking" philosophy. The present research provides some relevant outcomes concerning the design of a composite sample for the main landing gear bay of a large commercial airplane (EASA CS25 category), within ITEMB (InTEgrated Full Composite Main landing gear Bay Concept) project, a program of Clean Sky 2 EU research framework. The most ambitious goal is to develop a new generation of Lower Center Fuselage (LCF) with an innovative integrated landing system in the fuselage, which is considered the next frontier in the development of landing systems for medium-haul aircraft, such as the Airbus A320 aircraft family. The development of a different architecture, with the landing gear integrated within the related fuselage bay, could lead to a simplification of the whole sub-assembly with potential advantage in terms of construction and assembly times. Final target of the project is the manufacturing of an innovative monolithic composite structure that will replace the actual configuration (a mixed structure of metal and composite sub-assemblies) reducing or actually removing all the cost of assembly and increasing the production rate. This paper presents the main results of the work, introducing the main processing steps and prototype results; in the last part of the work, also some experimental test on significant element are introduced as first assessment of the technology readiness level that has been achieved
Progettisti a fumetti: quando la nona arte parla di progetto
No full textNonostante il fumetto rappresenti ancora un genere per alcuni aspetti di nicchia, negli ultimi anni si assiste a un momento di estrema vivacità editoriale che sottolinea le connessioni tra questi linguaggi narrativi e il mondo del design e dell’architettura. Quest’influenza, mai a senso unico, affonda le sue radici nella storia dell’architettura stessa, che a partire dagli anni ’60 con gli Archigram e prima con Le Corbusier, si confronta con il tema dell’ibridazione linguistica dando vita ad archi-fumetti e fumetti in- fografici. Nell’eterogenea produzione editoriale attuale risultano di particolare interesse dal punto di vista della rappresentazione le ‘biografie a fumetti’; un sottogenere in forte espansione che coinvolge principalmente il mondo della musica e dell’arte, ma che grazie alla recente collana proposta dalla casa editrice Centauria mostra negli ultimi dieci anni interesse anche verso l’area del progetto. Opere dedicate al lavoro e alla vita di progettisti come Le Corbusier, Sottsass, van der Rohe consentono in- teressanti riflessioni sulla modalità di comunicazione del processo progettuale e di rappresentazione delle opere.Tra queste, la presente ricerca si concentra su tre biografie edite nel 2019, dedicate ad altrettante progettiste: Eileen Gray, Lina Bo Bardi e Charlotte Perriand. Questi volumi indagano vita e lavoro di queste donne, dando il giusto spazio al loro ruolo nella storia e interpretando, in modi differenti, il loro apporto attraverso il disegno e il colore.In these years the comics are living, despite the fact that they are still a niche genre in some aspects, a moment of extreme editorial vivacity that underlines the connections between these narrative languages and the world of design and architecture.
This never one-way influence has its roots in the history of architecture itself, which, starting in the 60s with Archigram and before that with Le Corbusier, faces the theme of linguistic hybridization and gives life to archi-comics and infographic comics. ‘Comics biographies’ are, in the heterogeneous current editorial production, of particular interest from the representational point of view.This is a sub-genre in strong expansion, which mainly involves the world of music and art, the latter thanks to the recent series proposed by the publishing house Centauria, and which in the last ten years has also shown interest in the project sector. Graphic novels dedicated to the work and life of designers such as Le Corbusier, Sottsass, Mies allow interesting reflections on the way of communication and representation of the design process and of their works. Among them, the present research focuses on three biographies published in 2019 and dedicated to three female designers: Eileen Gray, Lina Bo Bardi and Charlotte Perriand.These volumes investigate the lives and work of these women, giving due space to their role in history and interpreting, in different ways, their contribution through drawing and color
Life for industrial sites End of Life
No full textIn the last decade, the decline in industrial settlements has emerged as an increasingly relevant and complex phenomenon, unveiling the limitations of the management models that are traditionally applied to these situations. This crucial problem is here addressed by adopting a conceptual framework, built to exploit a systemic perspective that moves from the recognition of the centrality of the company that used to inhabit the site. Specifically, operational guidelines are proposed and tested through their application to the case of enel’s power plant in Porto Tolle, being part of the Futur-e project. The results show how the conceptual model enables the identification of site-specific guidelines for the End Of Life (eol) strategy definition, and for the generation of opportunities for the entire area. If more traditional approaches were used, these opportunities would have remained undiscovered
Three-dimensional modeling of container cranes with deformable boom
No full textA three-dimensional model of container cranes accounting for the elastic interaction between the crane boom and the container dynamics is proposed. The container is modeled as a rigid body elastically suspended from the trolley moving on top of the crane boom. The Euler-Bernoulli beam model is adopted to describe the boom elasticity. The governing equations of motion are obtained employing the Euler-Lagrange equations whereby the boom kinetic and stored energies are introduced through a Galerkin discretization based on the mode shapes of the two-span crane boom taken as trial functions. Numerical investigations are carried out to evaluate the influence of the crane boom deformability on the dynamic response of the hoisted container especially when the response is nonlinearly excited by internal resonances. Comparisons with results obtained in a previous work where the boom dynamics were neglected are discussed
