Large systems-of-systems are developed by integrating several smaller systems that have been developed independently. System integration often requires adaptation mechanisms for bridging any technical incompatibilities between the systems. In order to develop adapters in a faster way, we study ways to generate adapters from a model-based specification.

There is a constant pressure on developers of embedded systems to simultaneously increase system functionality and to decrease development costs. Aviable way to obtain a better system performance with the same physical hardware is adaptivity: a system should be able to adapt itself to dynamically changing circumstances.

Adaptive systems engineering comprises two individual themes, adaptive systems and systems engineering, and their interaction. In the Octopus project, some challenges that arise from these themes have been addressed in the realm of professional printers. This chapter serves to place these challenges in a common context, which is done along the BAPO structuring principle (Business, Architecture, Process, Organisation).

Full flexible use of inkjet printhead units in printing systems requires consistent generation of drops with any given volume and velocity at any moment and place desired. True drop-on-demand is currently hampered by physical phenomena in the printhead. These are residual vibrations and crosstalk resulting from conventional jets.

How to develop adaptive high-tech embedded systems? This question has motivated this book. Adaptivity provides a wider operational envelope of systems and enables new market opportunities. Effective development of such systems requires a systematic approach that enables to include the adaptive capabilities at various system levels.

Context: Large software systems are usually developed by integrating several smaller systems, which may have been developed independently. The integration of such systems often requires the development of a custom adapter (sometimes called mediator or glue logic) for bridging any technical incompatibilities between the systems.

Much, if not most, information needed to assess a crisis situation originates these days from cooperative sources such as the Internet and social networks. Public safety authorities face the challenge to compile this information of uncertain origin and quality in their situation understanding and response planning.

This paper presents an approach to construct execution views, which are views that describe what the software of a software-intensive system does at runtime and how it does it. The approach represents an architecture reconstruction solution based on a metamodel, a set of viewpoints, and a dynamic analysis technique.

Wireless Sensor Networks (WSNs) are commonly deployed in dynamic environments where events, such as moving sensor nodes and changing external interference, impact the performance, or Quality-of-Service (QoS), of the network. QoS is expressed by the values of multiple, possibly conflicting, network quality metrics, such as network lifetime and maximum latency of communicating a packet to the sink.
