Since a sensor node consists of a microphone array with known intra-array geometry, we are able to obtain an absolute geometry estimate, including angles and distances.

We use a sample of 1,949 small private firms operating in the period 2006-2010 with optional financial statement audit. High quality data allows us to construct a more precise interest rate measure than existing studies employ. After controlling for obvious sources of demand for voluntary audits (ownership complexity, subsidiary status, bank relations), we find a robust central result that voluntary audits increase rather than decrease the cost of debt financing, contrary to several existing studies. This finding indicates that voluntary audits are generally treated as “adopting a label” and penalised by creditors, regardless of the perceived auditor quality as a result of the lemon problem in the audit market. Even Big-4 audits increase the cost of debt, likely as a result due to the lemon problem in the audit market, although the increase is smaller than for non-Big-4 audits. The results are sensitive to the estimation method used (OLS, Heckman’s two-step, PSM) and (sub-)sample selection. We show that disregarding the underlying assumptions of these estimation methods may lead to incorrect inferences. Additional analyses show that audited firms’ reported earnings are less informative about future operating performance than earnings of their unaudited counterparts. Our results also indicate that results are sensitive to cost of debt definition and this might have affected the results reported in the existing literature.","lang":"eng"}]},{"publication":"{Proceedings of the 8th International ACM SIGSOFT Conference on Quality of Software Architectures (QoSA)}","type":"conference","status":"public","_id":"22737","user_id":"4870","keyword":["model-driven performance engineering","self-*","Self-adaptation","software performance"],"publication_identifier":{"isbn":["978-1-4503-1346-9"]},"year":"2012","place":"New York, NY, USA","page":"117-122","citation":{"ama":"Becker M, Luckey M, Becker S.

To detect such changes during operation, process monitoring is desired. Labor intensive processes, that might be carried out for several hours, also require process monitoring to increase their reliability by detection of changes or malfunctions during operation. In some applications cavitation detection and monitoring can be achieved by the application of sensors in the sound field. Though the application of sensors is possible, this necessitates modifications on the system and the sensor might disturb the sound field. In other applications harsh, process conditions prohibit the application of sensors in the sound field. Therefore alternative techniques for cavitation detection and monitoring are desired.

Unforeseen influences could lead to dependability-critical behavior of the system. Methods are required which secure self-optimizing systems during operation. These methods to increase the dependability of the system should already be taken into consideration in the design process. This paper presents a guideline for the dependability-oriented design of self-optimizing systems, which integrates established classical methods like failure mode and effects analysis as well as methods based on self-optimization. On the one hand self-optimization is used to increase the dependability of the system by integrating objectives like safety, availability, and reliability to the objectives of the system. On the other hand methods are required to ensure the self-optimization itself. As basis for this guideline serves the principle solution of the system. The six phases of the guideline extend the design process and lead to an enhanced principle solution. Additionally, the guideline illustrates phases to implement and validate the self-optimizing system. The proposed guideline is applied to an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing function modules.","lang":"eng"}],"publication":"Industrial Informatics (INDIN), 2010 8th IEEE International Conference on","type":"conference","doi":"10.1109/INDIN.2010.5549490","title":"Guideline for the dependability-oriented design of self-optimizing systems","date_created":"2019-05-13T10:25:26Z","author":[{"first_name":"Christoph","full_name":"Sondermann-Wölke, Christoph","last_name":"Sondermann-Wölke"},{"id":"210","full_name":"Hemsel, Tobias","last_name":"Hemsel","first_name":"Tobias"},{"first_name":"Walter","full_name":"Sextro, Walter","id":"21220","last_name":"Sextro"},{"last_name":"Gausemeier","full_name":"Gausemeier, Jürgen","first_name":"Jürgen"},{"first_name":"Sebastian","full_name":"Pook, Sebastian","last_name":"Pook"}],"date_updated":"2022-01-06T07:04:19Z","page":"739 -744","citation":{"chicago":"Sondermann-Wölke, Christoph, Tobias Hemsel, Walter Sextro, Jürgen Gausemeier, and Sebastian Pook. “Guideline for the Dependability-Oriented Design of Self-Optimizing Systems.” In <i>Industrial Informatics (INDIN), 2010 8th IEEE International Conference On</i>, 739–44, 2010. <a href=\"https://doi.org/10.1109/INDIN.2010.5549490\">https://doi.org/10.1109/INDIN.2010.5549490</a>.","ieee":"C.

In contrary, self-optimization could be used to increase the dependability by pursuing objectives like reliability and availability. In our preceding publications we introduced the so called multi-level dependability concept to cope with this new kind of systems (cf. [6]). This concept comprises the monitoring of the system behavior, the classification of the current situation, and the selection of the appropriate measure, if reliability limits are exceeded. In this paper we present for the first time experimental results. The dependability concept is implemented in the self-optimizing active guidance system of a railway vehicle.

Self-optimizing systems are complex and due to their non-deterministic behavior comprise hidden risks, which cannot be foreseen in the design phase of the system. Therefore, this paper presents modifications of the current condition monitoring policy, to be able to cope with this new kind of systems. Beside avoiding critical situations evoked by self-optimization, the proposed concept uses self-optimization to increase the dependability of the system. In this case, the concept is applied to the active guidance module of an innovative rail-bound vehicle.","lang":"eng"}],"status":"public","date_updated":"2022-01-06T07:04:19Z","date_created":"2019-05-13T09:31:52Z","author":[{"first_name":"Christoph","full_name":"Sondermann-Wölke, Christoph","last_name":"Sondermann-Wölke"},{"first_name":"Walter","last_name":"Sextro","full_name":"Sextro, Walter","id":"21220"}],"title":"Towards the Integration of Condition Monitoring in Self-Optimizing Function Modules","doi":"10.1109/ComputationWorld.2009.47","year":"2009","page":"15 -20","citation":{"ama":"Sondermann-Wölke C, Sextro W.
