The development of systems comprising hardware and software components has been a demanding and complex problem. To manage the informational and architectural complexity inherent to these systems novel approaches are taken. In this chapter we present an approach that is based on the concepts of model driven architecture, platform based design, and hardware/software codesign.

The Internet paradigm implies the potential for infinite informational interconnectivity. In practice, it fast approaches a level of intensity, complexity etcetera where dedicated, say one-to-one, ad-hoc solutions hamper responsible usage and also further development. Generic technical solutions have of course been developed and made available as infrastructure. Being an informational infrastru...

Development of effective measures for the complexity of human–computer interface design based on a proper model is desirable in order to improve the human performance and to facilitate the system development. In this paper, the authors propose the task-to-action (TTA) model which can describe the task-performing procedure of human operators. Quantitative interface design complexity measures usi...

Increasingly, studies of genes and genomes are indicating that considerable horizontal transfer has occurred between prokaryotes. Extensive horizontal transfer has occurred for operational genes (those involved in housekeeping), whereas informational genes (those involved in transcription, translation, and related processes) are seldomly horizontally transferred. Through phylogenetic analysis o...

on, translation e horizontally . A. (1999) Proc. thesis. The underlying idea is that informational genes belong to large, complex systems of coevolving genes. Consequently, the likelihood of the successful horizontal transfer low. Here, this ode of ing to complex systems are relatively less likely to be under adaptive evolution. To evaluate this “extended complexity hypothesis”, 2,428 families ...

This study aimed at investigating the potential of collaborative and e-collaborative writing modalities in developing interactional complexity, utilization of interactional demonstrators and density of interaction. To this end, 66 Iranian intermediate female English as foreign language learners (EFL) were selected to participate in this study according to their scores on Oxford Placement Test (...
