The number of multi-sourced heterogeneous spatial datasets continues to grow and the fragmentation of organizational arrangements has caused much technical and non-technical heterogeneity. Spatial Data Infrastructures aim to facilitate spatial data use and sharing, and can be an effective platform to aid in data integration. This paper discusses the technical and non-technical heterogeneities o...

Variable renewable power sources are being integrated into power systems across the world. This restructuring process requires extensions of most parts of the power system infrastructure: generation, transmission, as well as storage capacity. Joint optimization of infrastructure extension and operation is a powerful method to identify technical solutions with minimal economic costs. This optimi...

Knowledge management solutions relying on central repositories sometimes have not met expectations, since users often create knowledge ad-hoc using their individual vocabulary and using their own individual IT infrastructure (e.g., their laptop). To improve knowledge management for such decentralized and individualized knowledge work, it is necessary to, first, provide a corresponding decentral...

This paper describes the technical approach behind our open, standards based infrastructure, how content providers can connect to it, and the value they can derive from doing so. A...

This paper discusses various approaches to risk analysis of infrastructure systems. The discussion is applied to electric power delivery systems, i.e. transmission and distribution of electric power, with an emphasis on the electric power grid in Sweden. In reviewing a number of the methods of risk analysis, it is concluded that methods from the systems safety and reliability discipline can to ...

A mediaspace is an audio, video and computing environment that supports distributed groups in their daily tasks by providing awareness, communication and collaboration services. Building on previous work on the social and technical issues of mediaspaces, we have identified three important design principles: integrability, flexibility and privacy. In this paper, we show how Web standards and pro...

The hydrological scienti c and operational communities are faced with new challenges. There is a demand for detailed water information for large regions and new environmental issues to deal with, which request advanced technical infrastructure merged with up-dated hydrological knowledge. Traditionally, the hydrological community is disaggregated. In this paper we suggest a collaborative approac...
