These so called self-optimizing systems adapt their objectives and behavior autonomously and flexibly to changing operating conditions. On the one hand, securing the dependability of such systems is challenging due to their complexity and non-deterministic behavior. On the other hand, self-optimization can be used to increase the dependability of the system during its operation. However, it has to be ensured, that the self-optimization works dependable itself. To cope with these challenges, the multi-level dependability concept was developed. It enables predictive condition monitoring, influences the objectives of the system and determines suitable means to improve the system's dependability during its operation. In this contribution we introduce a procedure for the conceptual design of an advanced condition monitoring based on the system's principle solution. The principle solution describes the principal operation mode of the system and its desired behavior. It is modeled using the specification technique for the domain-spanning description of the principle solution of a self-optimizing system and consists of a coherent system of eight partial models (e.g. requirements, active structure, system of objectives, behavior, etc.). The partial models are analyzed separately in order to derive the components of the multi-level dependability concept. In particular, the reliability analysis of the partial model active structure is performed to identify the system elements to be monitored and parameters to be measured. The principle solution is extended accordingly: e.g. with system elements required for the realization of the dependability concept. The advantages of the method are shown on the self-optimizing guidance module of a railroad vehicle.","lang":"eng"}],"place":"Helsinki, Finland","date_created":"2019-05-13T13:41:34Z","status":"public","keyword":["Mechatronic Systems","Principle Solution","Condition Monitoring","Conceptual Design"],"department":[{"_id":"151"}],"publication":"Proceedings of the 11th International Probabilistic Safety Assessment and Management Conference (PSAM11) and The Annual European Safety and Reliability Conference (ESREL2012)","author":[{"last_name":"Sondermann-Wölke ","full_name":"Sondermann-Wölke , Christoph","first_name":"Christoph"},{"last_name":"Meyer","first_name":"Tobias","full_name":"Meyer, Tobias"},{"last_name":"Dorociak","full_name":"Dorociak, Rafal","first_name":"Rafal"},{"last_name":"Gausemeier","first_name":"Jürgen","full_name":"Gausemeier, Jürgen"},{"full_name":"Sextro, Walter","first_name":"Walter","id":"21220","last_name":"Sextro"}],"quality_controlled":"1"},{"language":[{"iso":"eng"}],"year":"2012","citation":{"short":"M.

While these steps normally involve stiction and sliding, the motors can also operate in ``slip-slip'' mode without any phase of static friction. In this contribution, a one degree of freedom model of an inertia motor driven by an ideal actuator is analysed. Start-up and constant velocity operation of the motor are investigated and appropriate quantities to compare ``stick-slip'' and ``slip-slip'' operation are determined. Different aspects such as velocity, uniformity of motion, load capacity, robustness, efficiency, and wear are considered. The analysis allows both modes to be applied advantageously in different applications and can widen the field of application of piezoelectric inertia motors. Motor designers are enabled to choose the appropriate mode of operation and the best drive parameters for their individual applications.","lang":"eng"}]},{"volume":178,"has_accepted_license":"1","status":"public","date_created":"2018-08-23T12:37:40Z","author":[{"first_name":"J.","full_name":"Achtelik, J.","last_name":"Achtelik"},{"last_name":"Sievers","full_name":"Sievers, W.","first_name":"W."},{"full_name":"Lindner, Jörg","first_name":"Jörg","id":"20797","last_name":"Lindner"}],"publisher":"Elsevier BV","file_date_updated":"2018-08-23T12:39:27Z","publication":"Materials Science and Engineering: B","file":[{"date_updated":"2018-08-23T12:39:27Z","content_type":"application/pdf","relation":"main_file","success":1,"file_size":729276,"creator":"hclaudia","file_id":"4096","access_level":"closed","date_created":"2018-08-23T12:39:27Z","file_name":"Biomimetic approaches to create anti-reflection glass surfaces for solar cells using self-organizing techniques.pdf"}],"ddc":["530"],"user_id":"55706","article_type":"original","abstract":[{"lang":"eng","text":"Aiming to diminish the reflection losses of glass covered light harvesting devices, the optical reflectivity\r\nof nanostructured glass surfaces is studied theoretically and experimentally.
