Due to the convergence of various mobile access technologies like UMTS, WLAN, and WiMax the need for a new supporting infrastructure arises. This infrastructure should be able to support more efficient ways to authenticate users and devices, potentially enabling novel services based on the security provided by the infrastructure. In this paper we exhibit some usage scenarios from the mobile dom...

In evaluating an ongoing project to realise transaction services in the city state of Hamburg (Germany), this paper identifies the essential elements of an infrastructure for an e-government process portal and discusses how the findings could be generalised. Besides pressing ahead with standardisation and out-of-the-box approaches, research can make use of actornetwork theory to learn more abou...

Environment Climate Data Sweden (ECDS) is a new Swedish research infrastructure, furthering the reuse of scientific data in the domains of environment and climate. ECDS consists of a technical infrastructure and a service organization, supporting the management, exchange, and re-use of scientific data. The technical components of ECDS include a portal and an underlying data catalogue with infor...

The strength of the TISDAG (Technical Infrastructure for Swedish Directory Access Gateways) project’s DAG proposal is that it defines the necessary technical infrastructure to provide a single-accesspoint service for information on Swedish Internet users. The resulting service will provide uniform access for all information -the same level of access to information (7x24 service), and the same i...

This paper estimates a stochastic production frontier using time-series data for the aggregate Korean economy in 1977-2005 to examine whether public infrastructure stock reduces aggregate technical inefficiency in the gross domestic product. A stochastic production frontier is estimated in first-differenced form, and the one-sided residuals are regressed against the stock of public infrastructu...

Having regard to the necessity of maintaining the technical infrastructure in a proper condition that ensures production continuity, companies decide to implement modern methods of technological machines park management. These methods include TPM, RCM and outsourcing. Large companies, in particular, are ready to invest in the implementation of these methods because of a great number of machines...
