In industry, testing is commonly performed under severe pressure due to limited resources. Therefore, risk-based testing, which uses predicted risks to guide the test process, is employed to select test cases. To this end, risks have so far mainly been estimated ad hoc, but not systematically predicted on the basis of the defect history and defect costs. In this paper, we present a novel approach...
We present status and results of AstroGrid-D, a joint effort of astrophysicists and computer scientists to employ grid technology for scientific applications. AstroGrid-D provides access to a network of distributed machines with a set of commands as well as software interfaces. It allows simple use of computer and storage facilities and to schedule or monitor compute tasks and data management. It...
The field of e-science currently faces many challenges. Among the most important ones are the analysis of huge volumes of scientific data and the connection of various sciences and communities, thus enabling scientists to share scientific interests, data, and research results. These issues can be addressed by processing large data volumes on-thefly in the form of data streams and by combining multiple...
