Developing intelligent tools for the integration of information extracted from multiple heterogeneous sources is a challenging issue to eeec-tively exploit the numerous sources available on-line in global information systems. In this paper, we propose intelligent, tool-supported techniques to information extraction and integration which take into account both struc-tured and semistructured data...

Scenarios are widely used in industry to support requirements elicitation and validation. Tool support is a prerequisite for effective use and management of scenarios. In this paper we propose to integrate two scenario-based techniques developed in the ESPRIT Project CREWS. One supports the elicitation of a goal model from real-world scenarios. The other allows to validate a formal system speci...

We recently presented a framework for virtual reality integration into modern computational research techniques. We developed an environment in which one could theoretically view simulations of electron transfer in cytochrome proteins. Here, we actually implemented the simulation using the kinetic Monte Carlo method into the Unity Game Engine, allowing for immersive real-time rendering and mani...

The credibility of the scientific methodology of numerical models and their adequacy to form the basis of public policy decisions have been frequently challenged. The first part of this chapter aims to address the issue of model reliability by evaluating the current state of aquatic biogeochemical modeling. We provide evidence that there is still considerable controversy among modelers and the ...

In this paper we discuss issues concerning the development of interactive virtual reality (VR) environments. We argue that the integration of such type of environments with database technology has the potential of providing on one side much flexibility and on the other hand of resulting in enhanced interfaces for accessing contents from digital archives. The paper also describes a project deali...

Commercial computer-aided software engineering (CASE) tool technology has emerged as an important component of practical software development environments. Issues of CASE tool integration have received heightened attention in recent years, with various commercial products and technical approaches promising to make inroads into this difficult problem. One aspect of CASE integration that has not ...

The Borobudur temple (Indonesia) is one of the greatest Buddhist monuments in the world, now listed as an UNESCO World Heritage Site. The present state of the temple is the result of restorations after being exposed to natural disasters several times. Today there is still a growing rate of deterioration of the building stones whose causes need further researches. Monitoring programs, supported ...

In the context of model-based tool integration, model transformation languages are the first choice for realizing model exchange between heterogenous tools. However, the lack of a conceptual view on the integration problem and appropriate reuse mechanisms for already existing integration knowledge forces the developer to define model transformation code again and again for certain recurring int...
