Summary The vastly growing complexity of software enabled functionality – especially in the automotive industry where it is usually distributed over a network – requires also a steadily increasing number of test cases to ensure a high product quality. The automatic generation of test cases can ease this situation, but suffers from the well-known state space explosion problem, which is caused by the...
A well-founded testing theory encourages the practical application of test case generation techniques. This aims at overcoming the ever increasing complexity of software-enabled systems in the automotive industry. In this article we report on transforming UML Statecharts to the formal language LOTOS. The successful usage of UML Statecharts in our industrial setting and the availability of mature research...
Electrical capacitance tomography is targeted on estimating the spatial permittivity distribution of an inhomogeneous medium from measurements of trans-capacitance of a multi-electrode assembly outside the boundary of the medium. Since small changes in the measured data cause large or unbounded changes in recovered parameters, the problem is an ill-posed inverse problem. In this article, special focus...
