Using Architectural Runtime Verification for Offline Data Analysis

Lars Stockmann, Sven Laux, Eric Bodden
Analyzing runtime behavior as part of debugging complex component-based systems used in the vehicle industry is an important aspect of the integration process. It is a laborious task that involves many manual steps. One reason for this is that, as of today, the analysis is usually not performed on the...

How to Make the Right Diagnosis in Neutropenia

Elena E. Solomou, Christina Salamaliki, Maria Lagadinou
Isolated neutropenia without anemia or thrombocytopenia is a common clinical problem. The etiology of neutropenia may vary from transient bone marrow suppression, caused by self-limited viral illnesses, to previously undiagnosed congenital syndromes or serious systemic diseases. Consequently, determining...
