Real-world activity is complex and increasingly involves use of multiple computer applications and communication devices over extended periods of time. To understand activity at the level of detail required to provide natural and comprehensive support for it necessitates appreciating both its richness and dynamically changing context. In this article, we (1) summarize field work in which we rec...

Visualization of multiscale data is becoming increasingly important in all biomedical research projects. Huge amounts of data are being collected worldwide at all scale levels (from genes to body level). However, there is a clear lack of software tools to support the interactive inspection of these large data collections. A research consortium has been established to identify the challenges ass...

This paper presents MoSS-CC (Model-based Simulation System for Cost Calculation in wastewater treatment plants), a software tool to optimise wastewater treatment plant design and operation by means of simulation and cost analysis. The scenario analysis procedure is encoded in the software as a VPL (Virtual Product Lifecycle). Roughly, the scenario consists of two phases: the design phase and th...

E-learning at the workplace might be accomplished by synchronous cooperative learning sessions of small groups using net-based communication. This form of learning is suitable both for course-based e-learning as well as for knowledge transfer within the company. The small groups learn self-regulated, i.e. without the guidance of an instructor. However, the learning tasks are pre-defined and a s...
