Integration of 3D modelling with photogrammetry applied on historical images for cultural heritage
2023
The recovery of past architecture through 3D modelling is an important challenge today to the preservation of heritage. Decisive support for the interpretation of architecture can certainly come from historical images and old photographs that fix a portion of space at a specific time, keeping it unchanged over the years. This acquisition is decisive for studying architectures of the past that can be reinterpreted and analysed. Photos, in fact, capture the advance of time and the life of a building at a precise historical moment, becoming essential documents for the study and knowledge of heritage. An additional advantage is when these old images can be processed through Structure for Motion…
Experimental analysis of a thermoactive underground railway station
2022
Little is known about the real energy potential of thermoactive underground infrastructures, such as railway stations, that can act as a heating/cooling provider for the built environment. This study presents the results of thermomechanical full-scale in situ testing and numerical analysis of a thermoactive underground train station. The thermal performance and related geostructural impact of a portion of the new underground energy infrastructure (UEI) installed at the Lancy-Bachet train station in Geneva (Switzerland) are analyzed. Heating and cooling tests simulating real operative geothermal conditions are considered. Particular attention is given to ((i) the monitored wall-tunnel hydrot…
Nuove stazioni, periferie e città
2016
L’infrastruttura contemporanea amplia e fa slittare il proprio campo semantico, trasformandosi definitivamente da artefatto tecnico di carattere titanico ed epico ad elemento riparatore dei tessuti urbani, flessibile, trasformabile. In questo quadro in mutazione, numerose esperienze negli ultimi trent’anni hanno affermato in Europa occidentale il ruolo dei grandi progetti ferroviari come vettori di trasformazione urbana. A quindici anni dall’avvio della prima stagione di concorsi internazionali banditi per le nuove stazioni dell’Alta Velocità in Italia, è possibile un bilancio volto non solo al semplice confronto dei risultati direttamente pertinenti la realizzazione e l’esercizio dell’oper…
A Logic Fuzzy Model for Evaluation of the Railway Station’s Practice Capacity in Safety Operating Conditions
2013
Abstract The practice capacity of a railway junction depends, in addition to the effective operation’s conditions, by the potential risk factors related to the design plan of the railway station. With the aim of an approach based on the “fuzzy sets” it is possible to determine the numeric value of the practice capacity by the logic - qualitative relations between the features of the railway junction and the potential risk factors. This methodology permits to try out the absolute value of a suitable vector β, (less then the unit) for the utilization of the theoretic capacity in conditions of maximum reliability of the system related to the aspect of safety (technique “fail safe”).
