A self-optimizing system pursues objectives, of which the priorities can be changed at runtime, in turn changing the system behavior. When including system reliability as an objective of the system, it becomes possible to change the system based on the current reliability as well. This capability can be used to control the reliability of the system throughout its operation period in order to achieve a pre-defined or user-selectable system lifetime. This way, optimal planning of maintenance intervals is possible while also using the system capabilities to their full extent. Our proposed control system makes it possible to react to changed degradation behavior by selecting objectives of the self-optimizing system and in turn changing the operating parameters in a closed loop. A two-stage controller is designed which is used to select the currently required priorities of the objectives in order to fulfill the desired usable lifetime. Investigations using a model of an automotive clutch system serve to demonstrate the feasibility of our controller.

To do so, they generally select among several pre-defined working points. A common method to determine working points for a mechatronic system is to use model-based multiobjective optimization. It allows finding compromises among conflicting objectives, called objective functions, by adapting parameters. To evaluate the system behavior for different parameter sets, a model of the system behavior is included in the objective functions and is evaluated during each function call. Intelligent mechatronic systems also have the ability to adapt their behavior based on their current reliability, thus increasing their availability, or on changed safety requirements; all of which are summed up by the common term dependability. To allow this adaptation, dependability can be considered in multiobjective optimization by including dependability-related objective functions. However, whereas performance-related objective functions are easily found, formulation of dependability-related objective functions is highly system-specific and not intuitive, making it complex and error-prone. Since each mechatronic system is different, individual failure modes have to be taken into account, which need to be found using common methods such as Failure-Modes and Effects Analysis or Fault Tree Analysis. Using component degradation models, which again are specific to the system at hand, the main loading factors can be determined. By including these in the model of the system behavior, the relation between working point and dependability can be formulated as an objective function. In our work, this approach is presented in more detail. It is exemplified using an actively actuated single plate dry clutch system. Results show that this approach is suitable for formulating dependability-related objective functions and that these can be used to extend system lifetime by adapting system behavior.","lang":"eng"}],"date_created":"2019-05-20T13:19:37Z","keyword":["Self-optimization","multiobjective optimization","objective function","dependability","intelligent system","behavior adaptation"],"type":"journal_article","department":[{"_id":"151"}]},{"publication":"Proceedings of the 5th International Conference on Computational Methods","citation":{"apa":"Neuhaus, J., &#38; Sextro, W.

Within the power module package wire bonding is used as an interconnection technology. In recent years, aluminum wire has been used preferably, but an ever-growing market of powerful and efficient power modules requires a material with better mechanical and electrical properties. For this reason, a technology change from aluminum to copper is indispensable. However, the copper wire bonding process reacts more sensitive to parameter changes. This makes manufacturing reliable copper bond connections a challenging task. The aim of the BMBF funded project Itsowl-InCuB is the development of self-optimizing techniques to enable the reliable production of copper bond connections under varying conditions. A model of the process is essential to achieve this aim. This model needs to include the dynamic elasto-plastic deformation, the ultrasonic softening effect and the proceeding adhesion between wire and substrate. This paper focusses on the pre-deformation process. In the touchdown phase, the wire is pressed into the V-groove of the tool and a small initial contact area between wire and substrate arise. The local characteristics of the material change abruptly because of the cold forming. Consequently, the pre-deformation has a strong effect on the joining process. In [1], a pre-cleaning effect during the touchdown process of aluminum wires by cracking of oxide layers was presented. These interactions of the process parameters are still largely unknown for copper. In a first step, this paper validates the importance of modeling the pre-deformation by showing its impact on the wire deformation characteristic experimentally. Creating cross-section views of pre-deformed copper wires has shown a low deformation degree compared to aluminum. By using a digital microscope and a scanning confocal microscope an analysis about the contact areas and penetration depths after touchdown has been made. Additionally, it has to be taken into account that the dynamical touchdown force depends on the touchdown speed and the touchdown force set in the bonding machine. In order to measure the overshoot in the force signals, a strain gauge sensor has been used. Subsequently, the affecting factors have been interpreted independently Furthermore, the material properties of copper wire have been investigated with tensile tests and hardness measurements. In a second step, the paper presents finite element models of the touchdown process for source and destination bonds. These models take the measured overshoot in the touchdown forces into account. A multi-linear, isotropic material model has been selected to map the material properties of the copper. A validation of the model with the experimental determined contact areas, normal pressures and penetration depths reveals the high model quality. Thus, the simulation is able to calculate and visualize the three dimensional pre-deformation with an integrated material parameter of the wire if the touchdown parameters of the bonding machine are known. Based on the calculated deformation degrees of wire and substrate, it is probably possible to investigate the effect of the pre-deformation on the pre-cleaning phase in the copper wire bonding.","lang":"eng"}],"project":[{"name":"Intelligente Herstellung zuverlässiger Kupferbondverbindungen","_id":"92","grant_number":"02 PQ2210"}],"page":"289-294","language":[{"iso":"eng"}],"_id":"9895","user_id":"210","title":"Experimental and Numerical Simulation Study of Pre-Deformed Heavy Copper Wire Wedge Bonds","year":"2014","status":"public","author":[{"full_name":"Unger, Andreas","first_name":"Andreas","last_name":"Unger"},{"full_name":"Sextro, Walter","first_name":"Walter","last_name":"Sextro","id":"21220"},{"full_name":"Althoff, Simon","first_name":"Simon","last_name":"Althoff"},{"first_name":"Paul","last_name":"Eichwald","full_name":"Eichwald, Paul"},{"last_name":"Meyer","first_name":"Tobias","full_name":"Meyer, Tobias"},{"full_name":"Eacock, Florian","last_name":"Eacock","first_name":"Florian"},{"last_name":"Brökelmann","first_name":"Michael","full_name":"Brökelmann, Michael"}],"date_updated":"2020-05-07T05:33:47Z"},{"publication":"Proceedings of 8th International Conference on Integrated Power Electronic Systems","citation":{"apa":"Unger, A., Sextro, W., Althoff, S., Meyer, T., Brökelmann, M., Neumann, K., … Bolowski, D.

To implement a self-optimization technique for ultrasonic wire bonding machines, a model of the process is essential. This model needs to include the so called ultrasonic softening effect. It is a key effect within the wire bonding process primarily enabling the robust interconnection between the wire and a substrate. However, the physical modeling of the ultrasonic softening effect is notoriously difficult because of its highly non-linear character and the absence of a proper measurement method. In a first step, this paper validates the importance of modeling the ultrasonic softening by showing its impact on the wire deformation characteristic experimentally. In a second step, the paper presents a data-driven model of the ultrasonic softening effect which is constructed from data using machine learning techniques. A typical caveat of data-driven modeling is the need for training data that cover the considered domain of process parameters in order to achieve accurate generalization of the trained model to new process configurations. In practice, however, the space of process parameters can only be sampled sparsely. In this paper, a novel technique is applied which enables the integration of prior knowledge about the process into the datadriven modeling process. It turns out that this approach results in accurate generalization of the data-driven model to unseen process parameters from sparse data."}],"project":[{"name":"Intelligente Herstellung zuverlässiger Kupferbondverbindungen","grant_number":"02 PQ2210","_id":"92"}],"date_created":"2019-05-20T13:38:10Z","type":"conference","department":[{"_id":"151"}],"status":"public","title":"Data-driven Modeling of the Ultrasonic Softening Effect for Robust Copper Wire Bonding","year":"2014","author":[{"first_name":"Andreas","last_name":"Unger","full_name":"Unger, Andreas"},{"id":"21220","full_name":"Sextro, Walter","last_name":"Sextro","first_name":"Walter"},{"full_name":"Althoff, Simon","first_name":"Simon","last_name":"Althoff"},{"first_name":"Tobias","last_name":"Meyer","full_name":"Meyer, Tobias"},{"full_name":"Brökelmann, Michael","last_name":"Brökelmann","first_name":"Michael"},{"first_name":"Klaus","last_name":"Neumann","full_name":"Neumann, Klaus"},{"first_name":"René Felix","last_name":"Reimann","full_name":"Reimann, René Felix"},{"first_name":"Karsten","last_name":"Guth","full_name":"Guth, Karsten"},{"full_name":"Bolowski, Daniel","first_name":"Daniel","last_name":"Bolowski"}],"date_updated":"2020-05-07T05:33:47Z","intvolume":"       141","page":"175-180","_id":"9896","language":[{"iso":"eng"}],"user_id":"210","volume":141},{"year":"2014","status":"public","title":"On the Relation between Innovation and Competion: The Case of Energy Industry","author":[{"full_name":"Brummel, NinaMadeleine","first_name":"NinaMadeleine","last_name":"Brummel"}],"date_updated":"2022-01-06T06:59:54Z","_id":"392","publisher":"Universität Paderborn","user_id":"42447","citation":{"mla":"Brummel, NinaMadeleine. <i>On the Relation between Innovation and Competion: The Case of Energy Industry</i>.

There are a number of studies for safe node exclusion if the overlay is in a well-defined state initially. Surprisingly, the problem is not formally studied yet for the case in which the overlay network is in an arbitrary initial state, i.e., when looking for a self-stabilizing solution for excluding leaving nodes. We study this problem in two variants: the Finite Departure Problem (FDP) ) and the Finite Sleep Problem (FSP). In the FDP the leaving nodes have to irrevocably decide when it is safe to leave the network, whereas in the FSP, this leaving decision does not have to be final: the nodes may resume computation if necessary. We show that there is no self-stabilizing distributed algorithm for the FDP, even in a synchronous message passing model. To allow a solution, we introduce an oracle called NIDEC and show that it is sufficient even for the asynchronous message passing model by proposing an algorithm that can solve the FDP using NIDEC. We also show that a solution to the FSP does not require an oracle.","lang":"eng"}],"language":[{"iso":"eng"}],"series_title":"LNCS","doi":"10.1007/978-3-319-11764-5_4","year":"2014","title":"On Stabilizing Departures in Overlay Networks","author":[{"full_name":"Foreback, Dianne","first_name":"Dianne","last_name":"Foreback"},{"first_name":"Andreas","last_name":"Koutsopoulos","full_name":"Koutsopoulos, Andreas"},{"full_name":"Nesterenko, Mikhail","first_name":"Mikhail","last_name":"Nesterenko"},{"last_name":"Scheideler","first_name":"Christian","full_name":"Scheideler, Christian","id":"20792"},{"id":"11319","first_name":"Thim Frederik","last_name":"Strothmann","full_name":"Strothmann, Thim Frederik"}],"date_updated":"2022-01-06T06:59:56Z"},{"citation":{"ieee":"H.

To benefit from the growing plethora of available services, sophisticated service discovery approaches are needed that bring service requests and offers together. Such approaches rely on rich service descriptions, which specify also the behavior of provided/requested services, e.g., by pre- and postconditions of operations. As a base for the specification a data schema is used, which specifies the used data types and their relations. However, data schemas are typically heterogeneous wrt. their structure and terminology, since they are created individually in their diverse application contexts. As a consequence the behavioral models that are typed over the heterogeneous data schemas, cannot be compared directly. In this paper, we present an holistic approach to normalize rich service description models to enable behavior-aware service discovery. The approach consists of a matching algorithm that helps to resolve structural and terminological heterogeneity in data schemas by exploiting domain-specific background ontologies. The resulting data schema mappings are represented in terms of Query View Transformation (QVT) relations that even reflect complex n:m correspondences. By executing the transformation, behavioral models are automatically normalized, which is a prerequisite for a behavior-aware operation matching.","lang":"eng"}],"file":[{"date_created":"2018-03-20T06:59:55Z","creator":"florida","file_id":"1383","success":1,"content_type":"application/pdf","file_name":"394-SGHE14.pdf","access_level":"closed","file_size":1107805,"relation":"main_file","date_updated":"2018-03-20T06:59:55Z"}],"date_created":"2017-10-17T12:42:08Z","type":"conference","department":[{"_id":"66"}]},{"date_updated":"2022-01-06T06:59:58Z","publication_status":"published","author":[{"full_name":"Declair, Stefan","first_name":"Stefan","last_name":"Declair"},{"id":"158","last_name":"Förstner","first_name":"Jens","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens"}],"publication_identifier":{"eisbn":["978-981-4463-25-6"]},"title":"Simulation of Planar Photonic Resonators","year":"2014","language":[{"iso":"eng"}],"publication":"Handbook of Optical Microcavities","department":[{"_id":"15"}],"type":"book_chapter","keyword":["tet_topic_phc"],"date_created":"2018-08-20T10:33:51Z","file":[{"date_created":"2018-08-20T10:27:50Z","creator":"hclaudia","success":1,"content_type":"application/pdf","file_id":"3942","file_size":4806196,"access_level":"closed","file_name":"2013-04  Declair,Förstner_Simulation of Planar Photonic Resonators_Handbook-of-Optical-Microcavities.pdf","date_updated":"2018-08-20T10:27:50Z","relation":"main_file"}],"has_accepted_license":"1","status":"public","editor":[{"full_name":"Choi, Anthony H.W.","last_name":"Choi","first_name":"Anthony H.W."}],"volume":"Kapitel 2","ddc":["530"],"user_id":"55706","_id":"3941","publisher":"Pan Stanford Publishing Pte.

The goalof a node v is to minimize its private costs, i.e., the sum (SUM-game) ormaximum (MAX-game) of communication distances from v to all othernodes plus a fixed price α > 0 if it decides to be a gateway. Between gatewaysthe communication distance is 0, and gateways also improve othernodes’ distances by behaving as shortcuts. For the SUM-game, we showthat for α ≤ n − 1, the price of anarchy is Θ (n/√α) and in this rangeequilibria always exist. In range α ∈ (n−1, n(n−1)) the price of anarchyis Θ(√α), and for α ≥ n(n − 1) it is constant. For the MAX-game, weshow that the price of anarchy is either Θ (1 + n/√α), for α ≥ 1, orelse 1. Given a graph with girth of at least 4α, equilibria always exist.Concerning the dynamics, both games are not potential games. For theSUM-game, we even show that it is not weakly acyclic."}],"date_created":"2017-10-17T12:42:09Z","file":[{"date_created":"2018-03-20T06:59:20Z","creator":"florida","success":1,"content_type":"application/pdf","file_id":"1382","date_updated":"2018-03-20T06:59:20Z","relation":"main_file","file_size":161479,"access_level":"closed","file_name":"395-WINE2014ACJS.pdf"}],"department":[{"_id":"63"},{"_id":"541"}],"type":"conference","author":[{"first_name":"Sebastian","last_name":"Abshoff","full_name":"Abshoff, Sebastian"},{"first_name":"Andreas","last_name":"Cord-Landwehr","full_name":"Cord-Landwehr, Andreas"},{"id":"37827","last_name":"Jung","first_name":"Daniel","full_name":"Jung, Daniel"},{"id":"40384","last_name":"Skopalik","first_name":"Alexander","full_name":"Skopalik, Alexander"}],"title":"Multilevel Network Games","year":"2014","date_updated":"2022-01-06T06:59:59Z","series_title":"LNCS","language":[{"iso":"eng"}],"doi":"10.1007/978-3-319-13129-0_36","citation":{"bibtex":"@inproceedings{Abshoff_Cord-Landwehr_Jung_Skopalik_2014, series={LNCS}, title={Multilevel Network Games}, DOI={<a href=\"https://doi.org/10.1007/978-3-319-13129-0_36\">10.1007/978-3-319-13129-0_36</a>}, booktitle={Proceedings of the 10th International Conference on Web and Internet Economics (WINE)}, author={Abshoff, Sebastian and Cord-Landwehr, Andreas and Jung, Daniel and Skopalik, Alexander}, year={2014}, pages={435–440}, collection={LNCS} }","ama":"Abshoff S, Cord-Landwehr A, Jung D, Skopalik A.
