This document covers the logical and process architectures of provenance systems. The logical architecture identifies key roles and their interactions, whereas the process architecture discusses distribution and security. A fundamental aspect of our presentation is its technology-independent nature, which makes it reusable: the principles that are exposed in this document may be applied to diff...

Our group is involved in the European funded Webocracy project in which an e-government system called Webocrat has been designed and implemented. Our responsibility is to provide mechanisms guaranteeing secure and reliable access to Webocrat. According to the security requirements from the city councils involved in the project we have implemented a generic and extensible security architecture c...

An approach that simplifies software development of the model based decision support systems for environmental management has been introduced. The approach is based on definition and management of metadata and data related to computational model without losing data semantics and proposed methods of integration of the new modules 5 into the information system and their management. An architectur...

Since the late 80s there are a growing need of the machine tool builders and the end users to have open architecture controllers. Different levels of openness can be defined analyzing the available research results and products. The main initiatives leading the current research in these efforts are the European OSACA, the American OMAC and the OSEC from Japan. A complex comparison of these proj...

This work aims to the use of remotely web-based experiments to improve the learning process of automation and control systems theory courses. An architecture combining virtual learning environments, remote experiments, students guide and experiments analysis is proposed based on a wide state of art study. The validation of the architecture uses state of art technologies and new simple developed...

Given that acceptance of systems within the healthcare domain multiple papers highlighted the importance of integrating tools with the clinical workflow. This paper analyse how clinical context management could be deployed in order to promote the adoption of cloud advanced services and within the clinical workflow. This deployment will be able to be integrated with the eHealth European Interope...

+ IASTED International Conference on Applied Informatics, Innsbruck, Austria, February 2001 Abstract The next generation experiments in High Energy Physics are the driving force for setting up an International Data Grid at CERN, the European Organization for Nuclear Research. Hundreds of Petabytes of data will be distributed and replicated all over the globe starting from 2005. In order to anal...

Information management in disaster situations is challenging, yet critical for efficient response and recovery. Today information flows are difficult to establish, partial, redundant, overly complex or insecure, besides the interoperability between heterogeneous organisations is limited. This paper presents a novel system architecture that enables combining of several communication technologies...

An innovative approach is proposed for aligning the different layers of the enterprise architecture of a European institution. The main objective of the alignment targets the definition and the assignment of the access rights needed by the employees according to business specifications. This alignment is realized by considering the responsibility and the accountabilities (doing, deciding and ad...

Norm-enforcement models applied in human societies may serve as an inspiration for the design of multi-agent systems. Models for normenforcement in multi-agent systems often focus either on the intraor interagent level. We propose a combined approach to identify objectives for an architecture for self-regulating agents. In this paper we assess how changes on the inter-agent level affect the int...
