Testing is an important and cost-intensive part of the software development life cycle. Defect prediction models try to identify error-prone components, so that these can be tested earlier or more in-depth, and thus improve the cost-effectiveness during testing. Such models have been researched extensively, but whether and when they are applicable in practice is still debated. The applicability depends...
The hybrid low-level framework HL3 is a generic compilation target for high-level specification formalisms for hybrid systems. It is designed to support and validate the transformation of high-level specifications into executable code. We present a formal operational semantics for the execution of HL3 models, which assigns formal meaning to the high-level specification within a transformational approach...
Therapy of hypertension is still more or less empirical. Several classes of antihypertensive medications are known, the effect of which is based on different mechanisms. The efficacy of the treatment is not always a reliable indication of the appropriate selection as a good therapeutical response can sometimes be achieved at the expense of humoral simulation. This can lead to harmful increased synthesis...
