Engineers have severe requirements concerning: security of design data, quality of net connections, easiness of collaboration, etc. This article presents visions and middleware architecture to establish pan-European col- laborative engineering infrastructure and its application in the field of Electronic Design Automation (EDA). We present a transparent infrastructure to engineers to enable their Internet-based collaboration during the de- sign of complex electronic systems. In thi s context, we introduce an advanced collaborative infrastructure (ACI) for distance spanning, tool integration, and administration as well as open interfaces for XML-based data exchange. ACI constitutes a backbone for our collaborative research and engineering studies by fostering a combination of most recent plug-and-play technologies and secure, peer-to-peer data transfer with XML- based tool integration.

Currently, mobile computing devices cannot be seamlessly and flexibly obtain information about the context in which computing takes place. This requires dedicated personalization and localization in combination with advanced autocustomization techniques in order to adapt them to the needs of the current context. For natural interaction, for instance, many devices offer different input and output modalities, which enable different modes of operation to perform the same task. Auto-customization of modalities and devices in range can be obtained, if the system has sufficient information on the user’s preferences, abilities, the current situation, and the device that performs a specific task. To aid the system’s decision, we propose a set of interrelated and expandable profiles, which are prepared for automated adaptation, what will play a central part in making the technology to become invisible.}}, author = {{Schäfer, Robbie and Müller, Wolfgang}}, booktitle = {{Proceedings of the Joint Workshop IJCAI Workshop on Artificial Intelligence, Information Access, and Mobile Computing}}, title = {{{Adaptive profiles for Multi-Modal Interaction in Intelligent Frameworks}}}, year = {{2003}}, } @inproceedings{39364, abstract = {{The textual Object Constraint Language (OCL) is an of- ficial part of the Unified Modeling Language (UML).

We have therefore developed a temporal extension of OCL that enables modelers to specify behavioral state-oriented constraints. That work provides an alternative to the rather cryptic temporal logic formulae that are commonly used to specify behavioral system prop- erties. This article now illustrates that our OCL extension al- lows for specifying all kinds of properties that are regarded as relevant in practice.
