Infrastructure as interface. Thinking the urban and the high -speed station: italian case-studies.
2011
This presentation will document some results of an ongoing research focusing on the role of infrastructure in contemporary design practice. The methodology is based on critical design theory and combines theoretical aspects with a case-study approach, at the junction of infrastructure, urban design and architecture. It is already well documented that 19th and 20th century infrastructure have deeply affected their programs in order to face new challenges over the last 30 decades. Railway stations are leading examples in this fields: they have gradually implemented their design, that already integrated commercial spaces and facilities, until involving in public space transformation. Instead, …
LYON PART DIEU, HUB METROPOLITANO CONTEMPORANEO
2014
Lyon Part Dieu, contemporary metropolitan hub. By François Decoster, Djamel Klouche and Caroline Poulin. This article introduces a series of concepts developed by the AUC in its research on the theme of mobility, transportation, and stations in contemporary cities. The “inexorable station” in fact debates the need, for contemporary stations and more in general transportation venues, to evolve as projects for open spaces, to be porous with respect to the city while establishing with it an organic relationship. Stations are not just specialized venues dedicated to transportation, but more than ever they are becoming “initiators”, essential levers for urban development and regeneration in toda…
Modelling Airlines Competition on Fares and Frequencies of Service by Bi-level Optimization
2011
Abstract The research aims to understand how airlines make operative decisions on fares and frequencies of service in a competitive envi-ronment. A game approach has been developed to model the airlines’ choices in a duopolistic market. In particular, the short haul market for intercity linkages has been investigated. In this segment the air mode is in competition with other ground modes (i.e. road and high speed rail). A bi-level optimization program has been realized. The variables of model are: fares and frequencies of airlines.
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…
L'Alta Velocità in Cina. Politiche, strategie, territori
2014
High Speed railways in China. Policies, strategies and territories. by Marc Guigon The history of High-Speed railways in China is not a linear one, traced in the course of a rigorous planning process. It has on the contrary experienced moments of rapid surge, only to be followed by periods of slower growth. Fervid action, decision-making and euphoria have been accompanied by scathing failures, against a background of corruption and complex relations with the foreign providers of fundamental technology. The ! nal result is noteworthy however, because China currently has the largest High-Speed railroad network in the world, with a very high level of customer satisfaction, though the cost has …
LA CITTÁ DOPO IL PROGRESSO: LA STAZIONE DI STOCCARDA E L’AEROPORTO DI BERLINO
2014
The city post-progress: the station in Stuttgart and the airport in Berlin. by Florian Hertweck. In 2012 the Biennale di Venezia dedicated an entire room to the Hamburg Philharmonic. This was a tribute to the project by Herzog and De Meuron, but not for its splendid architecture, rather for the disaster represented by its construction. In a country which has built its identity around its faith in progress and growth, as much as its capacity for developing, on the national scale, a complex of technical, social and cultural infrastructures that is among the most competitive in the world, the inability to bring projects of this scope to term reveals a change in paradigm. In fact, the failure o…
STAZIONI DELL’ALTA VELOCITÁ IN GIAPPONE. TIPOLOGIA ARCHITETTONICA E URBANA DI UN MODELLO PRAGMATICO
2014
High-Speed railway stations in Japan. The architectural and urban typology of a pragmatic model. By Corinne Tiry-Ono The Japanese high-speed railway service was launched in 1964, during a time of rapid economic and demographic growth. It gave birth to a new, standardized generation of railway stations, and embodied the Tokaido Megalopolis. Originally centred on the capital city, its network now stretches across the entire country, seeking a better balance in terms of regional economic development and the revitalization of peripheral areas. Topographical constraints, natural risks and technical choices (elevated tracks, frequent tunnels, and speci! c rail gauge) led to a physically and techn…
New mobility strategies for the development of tourism in Sicily
2012
Tourism and Transport is a well established and inseparable pair. An areas can increase the tourism in potentially own economy. This requires suitable accommodation and adequate transportation system. A positive synergy effects are induced to increase of the site. Transport is an important growth area for tourism and as a result. A better functioning of transport facilitates access to sites, decreases the cost of transport and increases tourist flows. In Sicily there are a wealth of artistic, archaeological and natural sites, generating a tourist flows during the year. Despite this, the network of connections and services is precarious. Residents and visitors are inaccessible to certain geo…
AN INEXPENSIVE ULTRA-HIGH-SPEED PHOTOGRAPHIC TECHNIQUE
1968
Commercial Ultra-High-Speed Cameras for framing rates over 50,000 f.p.s. are very expensive and yield a small number of frames (8 to 24) per run. The single-flash technique with increasing delays gives photographs at a high framing rate over a comparatively long time and, as described here, requires no special electronic equipment except a good flash unit and a general-purpose oscilloscope.
Stretched fibre based dispersion compensating module for ultra high-speed telecommunication systems
2008
International audience; In this work, the potential efficiency of a low-loss, tunable second-and third-order dispersion compensating module based on a stretched optical fibre for ultra high-speed telecommunication systems is analysed. Experimental results at a repetition rate of 640 GHz show that precise dispersion compensation could be achieved in the range of +0.038 ps/nm by means of an 11.3 cm maximum stretching of a 48 m long dispersion compensating.
