A critical issue of the design of process-based software development tools and methodologies is the need to balance the desire for innovation with knowledge of past experiences and best practices. This tension between past knowledge and creating new knowledge is particularly acute in the software industry, which involves the development of a highly variable product that dictates the need for co...

Model-Driven Engineering has emerged as a software development paradigm that can assist in separating the issues of the problem space of a software system from the complexities of implementation in the solution space. As software systems have become more complex, a need for multiple abstractions to describe a single system has emerged. The development teams of these massive systems are also oft...

The definition or redesign of Public Administration (PA) procedures is particularly challenging. This is, for example, due to the requirement of cooperation of different organizational units and actors, different laws and procedures for the production of several artifacts, and maintaining traceability while integrating processes with new laws. We are interested in business process modeling and ...

Until recent times, most studies on supporting simulation-based scientific discovery learning adopted the ad hoc strategies-oriented approach. This paper makes a systematic analysis of the internal conditions of scientific discovery learning to propose a triple scheme for learning support design that includes interpretative support (IS), experimental support (ES), and reflective support (RS). T...

The Web is widely considered as a reliable and promising approach to design new information systems in various application areas such as geographical information systems. A flexible and interactive control of user actions and interactions must be implemented to ensure system consistency and make its evolution easier. The Web environment does not provide such a control. Combining both works from...

The report presents an architecture deenition language and various mappings to diierent programming languages. In addition, a major new idea is that the language contains features which are exploited to deene a concept to support cooperative distributed development of architectural descriptions. Besides the language and group-ware concepts the paper sketches functionality and implementation of ...

Virtual Reality (VR) is gaining in popularity and its added value for learning is being recognized. However, its richness in representation and manipulation possibilities may also become one of its weaknesses, as some learners may be overwhelmed and be easily lost in a virtual world. Therefore, being able to dynamically adapt the virtual world to the personal preferences, knowledge, skills and ...

Information technology tools associated with various educational activities often rely on different models of the needed information, support different cooperative styles, and are based on different media and technologies. The architecture of an open software platform which supports educational activities is presented in this paper. The architecture, which is based on a unifying data model, off...

Currently, popular operating systems are unable to support the end-toend real-time requirements of distributed continuous media. Furthermore, the integration of continuous media communications software into such systems poses significant challenges. This paper describes a design for distributed multimedia support in the Chorus micro-kernel operating system environment which provides the necessa...

The ROBOCARE project is aimed at creating an instance of integrated environment with software and robotic agents to actively assist an elderly person at home. In particular the project has synthesized a proactive environment for continuous daily activity monitoring in which an autonomous robot acts as a main interactor with the person. This paper accounts for the combination of features that cr...
