AbstractWith the current tendency of mass production towards customer-oriented serial production, blanking processes are facing new challenges. They require an increase in knowledge about faulty process conditions and their influence on the quality of a component as well as an instruction for a target-oriented adaptation of the process. The aim of this study is therefore to identify property deviations based on force-displacement curves and to establish correlations between the quality of the component and features of force-displacement curves. For this purpose, parameter variations are carried out on a high-speed press and features are extracted from these measured time series. Afterwards, the correlation between varying process parameters and features is carried out to obtain a conclusion about the condition of the component. The results of these studies for a regression analysis form the basis for a decision support system to identify deviations of the component as well as faulty process conditions. The paper shows that a reliable correlation between the quality of the component and force-displacement curves is possibly based on the feature engineering approach even under industrial boundary conditions. This also applies to the simultaneous modification and variations within a limited range of several process parameters.

In order to identify the existence of   an ontology of dependability, we conducted a bibliographic review. However, we encountered a real problem while researching and selecting articles that address this issue.  Indeed the research process in various scientific databases with standard techniques involve the application of a number of manual and duplicative steps. This makes it a fairly costly and faulty process. To surmount these challenges, we offer a solution that automates search and selection items. The proposed solution is essentially derived from the popular method called systematic mapping. In this article, we suggest a Web Service as an implementation of our proposed approach. This Web Service will allow users to query scientific databases to obtain the metadata of selected articles. Our proposal will make the selection of scientific articles easier and faster.

The terms we use in putting forward arguments may be ambiguous. When this is the case, our reasoning, however strictly we adhere to formal syllogistic rules, is apt to be fallacious. Here is a familiar text–book example of such a faulty process of thought.
