The Public-Key-Infrastructure of the Radiological Society of Germany.

2005

Pretty Good Privacy (PGP) encoding is based on the Public-Key-Procedure and permits the safe transmission of medical data. Furthermore it allows the use of an electronic signature provided that keys used belong to the key owner and that the key owner's identity is guaranteed by a trusted third party. Under the auspices of the Radiological Society of Germany (Deutsche Rontgengesellschaft, DRG) its IT-Working Group (Arbeitsgemeinschaft fur Informationstechnik, @GIT) built up an appropriate Certification Authority including the required Public-Key-Infrastructure. These @GIT certified PGP keys allow the legal use of telemedicine in Germany. Digital signatures based to those certified keys corre…

Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali

2019

I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…

The projects prepared for "Palermo South-East" are the result of a Graduate Laboratory structured through meetings seminars specialist communications critical exhibitions which - in a shared strategy - saw each student elaborate their work in comparison with others actors of the same Laboratory. The research on "urban projects" was set so that each graduating student was made aware of the projects carried out in the same geographical area by the colleagues who had preceded it so as to be able to operate in continuity and contribute to formulating a unitary reasoning in which each project constituted continuation verification or even variant of the previous ones. These coordinated works have pursued two fundamental objectives: the strengthening of infrastructures and the establishment of specialized public buildings with superior functions aimed at requalifying and regenerating various critical situations with particular attention to the relationship between context and life scenarios. Thus each designer while dealing with a main functional program simultaneously deals with various issues such as the rationalization of the road system the redevelopment of existing buildings the design and refunctionalization of urban services (for example the transformed Central Station in the hotel or the project of a great Mosque)several degree theses have addressed as the main theme or as a question in the background the design of a new bed for the Oreto river and the relative establishment of a park facing it. In this desire to "patch up the wounds" in the different areas of "Palermo South-East" in close relationship with the vicissitudes of the place there is a continuous reference to architectures of all time and some questions involving the functional program are suggested - that identifies the character (or perhaps "type") of what is to be inserted in a given context - and the qualities of living reality as a pivotal material in the design process.Settore ICAR/14 - Composizione Architettonica E Urbana

Productivity, Infrastructures and Convergence: Panel Data Evidence on Italian Regions

2008

The paper first employs the Growth Accounting methodology in order to calculate the annual levels of Total Factor Productivity (TFP) in Italian regions for the period 1970-2001. The main result of this initial analysis is that the well-known gap in labour productivity among Italian regions depends mostly on the differences in TFP. The paper then investigates on the presence (or absence) of regional convergence in TFP over the period considered. To this end, physical and social infrastructures are taken into account as factors that influence the process of convergence. Finally, the paper finds a significant effect of both types of infrastructure on regional convergence in TFP, which is estim…

Traffic fundamentals for A22 Brenner freeway by microsimulation models.

La tesi di dottorato ha avuto come tema lo studio e l’applicazione di un modello di micro-simulazione del traffico in ambito autostradale. Essa si compone di quattro capitoli, con ognuno dei quali si è voluto sintetizzare e descrivere il lavoro di studio e ricerca svolto durante il suddetto corso di Dottorato di Ricerca. L’obiettivo principale del presente lavoro di tesi è stato quello di mettere a punto una metodologia finalizzata all’ottenimento delle relazioni fondamentali di deflusso in ambito autostradale attraverso il software di microsimulazione del traffico Aimsun. Come risulta infatti noto dalla letteratura scientifica, le relazioni fondamentali del deflusso sono utilizzate nel cam…

Infrastructure as Interface: Thinking the Urban and the High-speed Railway Station: Italian Case-studies

2013

The recent launching in Italy of a number of large scale urban operations centered around High Speed Railway (HSR) stations has added a wealth of examples and themes to the overall European picture; these go to make up a global point of reference for other countries that are, in this period, undertaking the construction of their own HSR networks. Above and beyond the territorial questions often linked to the issue, further research investigating the architectural aspect of these operations would be highly relevant, but is rather lacking. Instead, we shall be focusing on current HSR stations in Italy, such as Turin Porta Susa, Florence Belfiore and Rome Tiburtina, and comparing them briefly,…

Development of International Freight Transit in Latvia

2013

Abstract International freight transit is transportation of goods through third countries which are neither senders or consumers of the transported freight. International freight transit provides the use of transport infrastructure capacities and the development of transport infrastructure in Latvia, especially in seaports and railways. In Latvia approximately 97% of all transported freight carried by railway is international freight transit. The turnover of Latvia's seaports is approximately 90% international freight transit transport. This paper describes comparative position of Latvia in Logistics Performance Index and assesses international competitiveness of Latvia's international frei…

In the rail sector, France needs to do more to connect its regional networks to the European network

2023

In an article for "Le Monde" newspaper, the legal expert Martial Pernet notes that, despite the texts in force, which he urges to be applied, efforts must be made to achieve the unification of the European rail network.

The effect of cooperative infrastructure fees on high-speed rail and airline competition

2021

Abstract This paper explores the effects of cooperation between rail and air infrastructures in setting per-passenger fees prior to competition among airlines and high-speed rail (HSR) in a transport network. It is shown that, for a sufficiently low degree of substitution, cooperation results in lower fees and greater HSR traffic than under competition. Besides, it leads to more connecting passengers. An empirical application allows for a quantitative assessment of cooperation. Gains to passengers and operators are sizeable when cooperation either involves all infrastructure managers or the rail and the hub airport managers. Welfare gains are in the range of 10.4–11.1%. Our contribution off…
