Model transformation languages are crucial for the success of Model-Driven Engineering (MDE), being comparable to the importance of compilers for high-level programming languages. The support of large transformation scenarios, however, is still in its infancy since the development of transformations currently takes place on a low-level of abstraction, lacking appropriate reuse mechanisms. We pr...

1. Introduction Modern automobiles, featuring increased convenience, safety, and energy savings, have become more and more reliant on the outcomes of the IT industry. Existing services such as vehicle tracking, navigation and emergency notification envision a promising future of more powerful computing-assisted automobile systems. Some examples include remote vehicle controllers, short range br...

Developers of distributed embedded systems face challenges of high demands on reliability and performance, requirements on lowered product cost, and supporting many configurations, variants and suppliers. Component-based development is a promising software engineering approach to cost efficiently deal with software variability, reusability and maintainability. However, we claim that existing to...

Despite the variety of tools to support the development of multi-agent systems (MAS), the implementation of such systems remains expensive and adhoc. This is caused by the difficulty or, in some cases, impossibility, of tailoring and successfully applying these tools due to their lack of flexibility. In this paper we propose object-oriented frameworks as a technique to build tailorable and reus...

Intelligent mobile systems such as Deep Map, a mobile tourist guide, require a range of intelligent components in order to actually go beyond classical systems. These components cover smart user interfaces, designed for mobile use and incorporating the use of natural language. They also include services that are location dependent, make use of context information and that allow access to a vari...

Clocks with a bounded drift rate are an important tool in the construction of dependable applications. However, the drift rates of clocks provided by operating systems on some computing platforms are not always bounded, e.g. due to lost interrupts. We show how one can build clocks with a bounded drift rate from components off-the-shelf (COTS). Our approach can be used to achieve a tight synchro...

In this paper we present results on the systematic reuse of components in a number of large scale applications. The applications have been developed in CHIP, a Prolog based constraint logic programming system. We show that even though the applications solve very different problems, we can reuse large parts of the data model and graphical user interfaces. We describe several very high level comp...

The primary aim of the Integrative Biology (IB) project is to develop a second generation ”Hybrid Grid” to support post-genomic research in integrative biology. The requirements for the grid and applications middleware were determined by considering the needs of two vitally important clinical areas, cardiovascular disease and cancer. Component services of the IB grid have been in use by the sci...
