As the technical infrastructure to support Grid environments matures, attention must be focused on integrating such technical infrastructure with technologies to support more dynamic access to services, and ensuring that such access is appropriately monitored and secured. Current approaches for securing organisations thorugh conventional firewalls are insufficient; access is either enabled or d...

This paper presents strategic visions, scenarios and action plans for enhancing Tanzania Power Systems towards next generation Smart Power Grid. It first introduces the present Tanzanian power grid and the challenges ahead in terms of generation capacity, financial aspect, technical and non-technical losses, revenue loss, high tariff, aging infrastructure, environmental impact and the interconn...

Delivery of electronic services requires a service infrastructure including organisational solutions for logistics and client-organisation interactions. We report a study covering three years of efforts by nine cities in eight European countries in developing such solutions. We found twelve distinct “crises”, situations where goals, environment, and actors changed, and the process was found in ...

BABS is an acronym for Library Archiving and Access System (Bibliothekarisches Archivierungsund Bereitstellungssystem), which constitutes the infrastructure for digital long-term preservation at the Bavarian State Library (BSB). During the two-year project BABS2 funded by German Research Association (DFG) BSB focuses together with the LeibnizSupercomputing Centre (LRZ) on advancing its organiza...

The notion of information infrastructures, introduced in the 1990s and refined during the past ten years, has proven quite fruitful to the IS field. It changed the perspective from organizations to networks and from systems to infrastructures, allowing for a global and emergent perspective on information systems. However, something is missing in this theory. What is an information infrastructur...

SAP HANA started as one of the best-performing database engines for OLAP workloads strictly pursuing a main-memory centric architecture and exploiting hardware developments like large number of cores and main memories in the TByte range. Within this paper, we outline the steps from a traditional relational database engine to a Big Data infrastructure comprising different methods to handle data ...

The KIM platform provides a novel Knowledge and Information Management infrastructure and services for automatic semantic annotation, indexing, and retrieval of documents. It provides mature infrastructure for scaleable and customizable information extraction (IE1) as well as annotation and document management, based on GATE2. In order to provide basic level of performance and allow easy bootst...

In 1993 the interconnection of three local ATM-based networks in Berlin was initiated by DeTeBerkom , the Gesellschaft für Mathematik und Datenverarbeitung (GMD) and the Technical University of Berlin (TUB). This paper describes the goals of this Berlin ATM LAN Interconnection (BALI) [Hartenthaler 94] and presents first results. Section 1 introduces the infrastructure of the BALI network in its...

The technical details of Internet architecture affect social debates about privacy and autonomy, intellectual property, cybersecurity, and the basic performance and reliability of Internet services. This paper explores one method for practicing anticipatory ethics in order to understand how a new infrastructure for the Internet might impact these social debates. This paper systematically examin...

For the distributed control of an electricity infrastructure incorporating clusters of residential combined heat and power units (micro-CHP or μCHP) a Multi-Agent System approach is considered. The network formed by households generating electricity with μCHP units and the facilitating energy supplier can be regarded as an electricity production system, analogous to a (flexible) manufacturing s...
