Security measures are designed, operated and maintained by different roles along product and production system lifecycles. Defense-in-Depth as a paradigm builds upon the assumption that breaches are unavoidable. The paper at hand provides an analysis of roles, corresponding Human Factors and their relevance for data theft and sabotage attacks. The resulting taxonomy is reflected by an example related to Additive Manufacturing. The results assist in both designing and redesigning Industrial Control System as part of an entire production system so that Defense-in-Depth with regard to Human Factors is built in by design.","lang":"eng"}],"date_created":"2023-08-15T12:21:05Z","publisher":"IEEE","title":"Re-Envisioning Industrial Control Systems Security by Considering Human Factors as a Core Element of Defense-in-Depth","quality_controlled":"1","year":"2023","user_id":"58331","department":[{"_id":"34"},{"_id":"152"},{"_id":"76"},{"_id":"632"},{"_id":"858"}],"_id":"46500","file_date_updated":"2024-09-05T13:00:09Z","type":"conference","status":"public","author":[{"first_name":"Jens","full_name":"Pottebaum, Jens","id":"405","last_name":"Pottebaum","orcid":"http://orcid.org/0000-0001-8778-2989"},{"first_name":"Jost","full_name":"Rossel, Jost","id":"58331","orcid":"0000-0002-3182-4059","last_name":"Rossel"},{"full_name":"Somorovsky, Juraj","id":"83504","orcid":"0000-0002-3593-7720","last_name":"Somorovsky","first_name":"Juraj"},{"full_name":"Acar, Yasemin","id":"94636","last_name":"Acar","first_name":"Yasemin"},{"id":"111","full_name":"Fahr, René","last_name":"Fahr","first_name":"René"},{"first_name":"Patricia","last_name":"Arias Cabarcos","full_name":"Arias Cabarcos, Patricia","id":"92804"},{"orcid":"0000-0003-3470-3647","last_name":"Bodden","id":"59256","full_name":"Bodden, Eric","first_name":"Eric"},{"first_name":"Iris","full_name":"Gräßler, Iris","id":"47565","orcid":"0000-0001-5765-971X","last_name":"Gräßler"}],"date_updated":"2025-07-16T11:06:47Z","main_file_link":[{"url":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10190647"}],"conference":{"end_date":"2023-07-07","location":"Delft, Netherlands","name":"2023 IEEE European Symposium on Security and Privacy Workshops (EuroS&PW)","start_date":"2023-07-03"},"doi":"10.1109/eurospw59978.2023.00048","publication_status":"published","has_accepted_license":"1","citation":{"mla":"Pottebaum, Jens, et al. “Re-Envisioning Industrial Control Systems Security by Considering Human Factors as a Core Element of Defense-in-Depth.” <i>2023 IEEE European Symposium on Security and Privacy Workshops (EuroS&#38;PW)</i>, IEEE, 2023, pp. 379–85, doi:<a href=\"https://doi.org/10.1109/eurospw59978.2023.00048\">10.1109/eurospw59978.2023.00048</a>.","short":"J.

Based on interpreting the identified concepts vis-à-vis the extant research and considering a temporal perspective on the concepts’ application, we present a lexicon of platform concepts, to guide further research on platforms in the IS discipline.

Due to the numerous physical influencing factors, it is very difficult to accurately capture\r\nthis process in a model. Therefore, our goal is to determine a suitable feed-forward control strategy for the\r\nbonding process even without detailed model knowledge. We propose the use of batch constrained Bayesian\r\noptimization for the control design. Hence, Bayesian optimization is precisely adapted to the application of\r\nbonding: the constraint is used to check one quality feature of the process and the use of batches leads to\r\nmore efficient experiments. Our approach is suitable to determine a feed-forward control for the bonding\r\nprocess that provides very high quality bonds without using a physical model. We also show that the quality\r\nof the Bayesian optimization based control outperforms random search as well as manual search by a user.\r\nUsing a simple prior knowledge model derived from data further improves the quality of the connection.\r\nThe Bayesian optimization approach offers the possibility to perform a sensitivity analysis of the control\r\nparameters, which allows to evaluate the influence of each control parameter on the bond quality.

Automated approximate accelerator synthesis involves a great deal of complexity on the size of design space which exponentially grows with the number of possible approximations. Design space exploration of approximate accelerator synthesis is usually targeted via heuristic-based search methods. The majority of existing frameworks prune a large part of the design space using a greedy-based approach to keep the problem tractable. Therefore, they result in inferior solutions since many potential solutions are neglected in the pruning process without the possibility of backtracking of removed approximate instances. In this paper, we address the aforementioned issue by adopting Monte Carlo Tree Search (MCTS), as an efficient stochastic learning-based search algorithm, in the context of automated synthesis of approximate accelerators. This enables the synthesis frameworks to deeply subsamples the design space of approximate accelerator synthesis toward most promising approximate instances based on the required performance goals, i.e., power consumption, area, or/and delay. We investigated the challenges of providing an efficient open-source framework that benefits analytical and search-based approximation techniques simultaneously to both speed up the synthesis runtime and improve the quality of obtained results. Besides, we studied the utilization of machine learning algorithms to improve the performance of several critical steps, i.e., accelerator quality testing, in the synthesis framework. The proposed framework can help the community to rapidly generate efficient approximate accelerators in a reasonable runtime."}],"publication":"Proceedings of IEEE Computer Society Annual Symposium on VLSI","type":"conference"},{"abstract":[{"lang":"eng","text":"Platform-based business models underlie the success of many of today’s largest, fastest-growing, and most disruptive companies.

Plattformanbieter müssen auf ad-hoc Entscheidungen zurückgreifen. Dies kann dann zu Problemen im Betrieb der Software-Plattformen führen, zu erhöhten Ausfallrisiken und Mehrkosten.\r\n\r\nDer Mangel an Architekturwissen manifestiert sich konkret in zwei Gruppen von Herausforderungen: Erstens fehlt eine Wissensbasis zu Architekturalternativen und zweitens fehlt es an methodischem Wissen zu Entwicklung und Betrieb von Software-Ökosystemen. Eine Architekturwissensbasis würde Orientierungshilfen zu den Bestandteilen von Software-Ökosystemen und deren Abhängigkeiten geben, während methodisches Wissen die Erstellung dieser Systeme erleichtern würde.\r\n\r\nIn der Dissertation werden diese Herausforderungen durch die Entwicklung des Frameworks SecoArc für die Modellierung von Software-Ökosystemen angegangen. Der Beitrag der Dissertation ist zweifach: \r\n1.\tDas SecoArc-Framework umfasst eine Architekturwissensbasis, die wiederverwendbare Architekturentwurfsentscheidungen\r\nvon Software-Ökosystemen enthält. Die Wissensbasis wurde entwickelt, indem das Architekturwissen bestehender Ökosysteme sowie aus existierender Fachliteratur ermittelt wurde und in einer Produktlinie für Software-Ökosysteme konsolidiert wurde. Die Produktlinie umfasst architektonische Gemeinsamkeiten und Variabilitäten von Software-Ökosystemen. \r\n2.\tDas SecoArc-Framework liefert methodisches Wissen, um die Ökosystemarchitektur in Modellen zu entwerfen und zu analysieren. Dieses Wissen wurde entwickelt, indem drei Architekturmuster identifiziert wurden. Jedes Muster erfasst unterschiedliche Beziehungen zwischen architektonischen Entwurfsentscheidungen zu den Qualitätsmerkmalen einer Ökosystemgesundheit und der Erreichung von Geschäftszielen. \r\n\r\nDie Architekturmuster und die Produktlinie wurden dazu genutzt, ein Modellierungsframework zu entwickeln und in Form eines Prototypen umzusetzen, welches einen Entwurfsprozess, eine Modellierungssprache und eine Architekturanalysetechnik umfasst. Es erleichtert das Modellieren, Analysieren und Vergleichen von Ökosystemarchitekturen.\r\n\r\nDie Ergebnisse der Dissertation wurden im Rahmen von zwei Studien evaluiert. In der ersten Validierungsstudie wurden das Framework sowie der Prototyp verwendet, um zwei alternative Ökosystemarchitekturen zu entwerfen und zu analysieren. In der zweiten Studie wurde eine Analyse von existierenden Ökosystemen basierend auf den architektonischen Variabilitäten des Frameworks durchgeführt.","lang":"ger"}]},{"language":[{"iso":"eng"}],"keyword":["Ultrasonic heavy wire bonding","Co-simulation","ANSYS","MATLAB","Process optimization","Friction coefficient","Copper-copper","Aluminium-copper"],"user_id":"210","department":[{"_id":"151"}],"_id":"21436","status":"public","abstract":[{"text":"Ultrasonic wire bonding is a solid-state joining process, used in the electronics industry to form electrical connections, e.g. to connect electrical terminals within semiconductor modules. Many process parameters affect the bond strength, such like the bond normal force, ultrasonic power, wire material and bonding frequency. Today, process design, development, and optimization is most likely based on the knowledge of process engineers and is mainly performed by experimental testing. In this contribution, a newly developed simulation tool is presented, to reduce time and costs and efficiently determine optimized process parameter. Based on a co-simulation of MATLAB and ANSYS, the different physical phenomena of the wire bonding process are considered using finite element simulation for the complex plastic deformation of the wire and reduced order models for the transient dynamics of the transducer, wire, substrate and bond formation. The model parameters such as the coefficients of friction between bond tool and wire and between wire and substrate were determined for aluminium and copper wire in experiments with a test rig specially developed for the requirements of heavy wire bonding. To reduce simulation time, for the finite element simulation a restart analysis and high performance computing is utilized. Detailed analysis of the bond formation showed, that the normal pressure distribution in the contact between wire and substrate has high impact on bond formation and distribution of welded areas in the contact area.","lang":"eng"}],"type":"journal_article","publication":"Microelectronics Reliability","doi":"https://doi.org/10.1016/j.microrel.2021.114077","title":"Co-simulation of MATLAB and ANSYS for ultrasonic wire bonding process optimization","author":[{"full_name":"Schemmel, Reinhard","id":"28647","last_name":"Schemmel","first_name":"Reinhard"},{"first_name":"Viktor","last_name":"Krieger","full_name":"Krieger, Viktor"},{"last_name":"Hemsel","id":"210","full_name":"Hemsel, Tobias","first_name":"Tobias"},{"last_name":"Sextro","full_name":"Sextro, Walter","id":"21220","first_name":"Walter"}],"date_created":"2021-03-10T09:37:02Z","volume":119,"date_updated":"2023-09-21T14:15:33Z","citation":{"mla":"Schemmel, Reinhard, et al. “Co-Simulation of MATLAB and ANSYS for Ultrasonic Wire Bonding Process Optimization.” <i>Microelectronics Reliability</i>, vol. 119, 2021, p. 114077, doi:<a href=\"https://doi.org/10.1016/j.microrel.2021.114077\">https://doi.org/10.1016/j.microrel.2021.114077</a>.","short":"R.

Rivets for self-piercing riveting differ in their geometry, the material used, the condition of the material and their surface condition. To shorten the manufacturing process by omitting the heat treatment and the coating process, the authors have elaborated a concept for the use of stainless steel with high strain hardening as a rivet material. The focus of the present investigation is on the evaluation of the influences of the rivet’s geometry and material on its deformation behaviour. Conventional rivets of types P and HD2, a rivet with an improved geometry made of treatable steel 38B2, and rivets made of the stainless steels 1.3815 and 1.4541 are examined. The analysis is conducted by means of multi-step joining tests for two material combinations comprising high-strength steel HCT70X and aluminium EN AW-5083. The joints are cut to provide a cross-section and the deformation behaviour of the different rivets is analysed on the basis of the measured changes in geometry and hardness. In parallel, an examination of the force-stroke curves provides further insights. It can be demonstrated that, besides the geometry, the material strength, in particular, has a significant influence on the deformation behaviour of the rivet. The strength of steel 1.4541 is seen to be too low for the joining task, while the strength of steel 1.3815 is sufficient, and hence the investigation confirms the capability of rivets made of 1.3815 for joining even challenging material combinations."}],"status":"public","_id":"22930","user_id":"53912","department":[{"_id":"157"}],"keyword":["Self-piercing riveting","Lightweight design","Deformation behaviour","Stainless steel","High nitrogen steel"],"language":[{"iso":"eng"}],"publication_status":"published","quality_controlled":"1","place":"Cham","year":"2021","citation":{"short":"B.

This approach involves so-called Huygens' box as an efficient radiation model inside an electromagnetic (EM) simulation tool and then transforms the scanned NF measured data into the FF. For this, the basic idea of the Huygens'box principle and the NF-to-FF transformation are briefly presented. The NF is measured on the Huygens' box around a device under test using anNF scanner, recording the magnitude and phase of the site-related magnetic and electric components. A comparison between a fullwave simulation and the measurement results shows a good similarity in both the NF and the simulated and transformed FF.Thus, this method is applicable to predict the FF behaviour of any electronic system by measuring the NF. With this knowledge, the RF design can be improved due to allowing a significant reduction of EM compatibility failure at the end of the development flow. In addition, the very efficient FF radiation model can be used for detailed investigations in various environments and the impact of such an equivalent radiation source on other electronic systems can be assessed."}],"keyword":["Huygens' box","NF-to-FF transformation","efficient FF radiation model","FF behaviour","EMI assessment","PCB","near-field measurements","efficient radiation model","far-field behaviour","RF design process","far-field prediction","Huygens'box principle","fullwave simulation","electronic system radiation","equivalent radiation source","electromagnetic simulation tool","near-field scan data","EM compatibility failure reduction"],"language":[{"iso":"eng"}],"edition":"1","year":"2020","publisher":" The Institution of Engineering and Technology (IET)","date_created":"2021-03-18T13:49:49Z","title":"Far-field prediction combining simulations with near-field measurements for EMI assessment of PCBs"},{"publication":"28th European Conference on Information Systems (ECIS 2020)","type":"conference","abstract":[{"lang":"eng","text":"Understanding a new literature corpus can be a grueling experience for junior scholars.

From the perspective of potential students, these programmes are highly attractive because they combine types of learning that used to be largely separate at an institutional level: vocational and academic learning. In training-integrated dual study programmes, different institutional contexts, governance regimes, teaching styles and learning environments make bridging these two worlds of learning a challenge for both educators and learners. However, these programmes also allow leeway for didactic innovation, through the cooperation of different types of educational institutions and through new ways of using available didactic methods, and for establishing a new relationship between higher education (HE) and vocational education and training (VET). This paper positions training-integrated dual study programmes as an object of design-based research (DBR). By developing and using an extended model for the pedagogic development of HEIs, “pädagogische Hochschulentwicklung” (Brahm, Jenert, &amp; Euler, 2016a, p. 19; Euler, 2013, p. 360), the paper systematically identifies generic educational problems in these hybrids. Based on a literature review, this paper classifies and explains the design challenges at the level of the learning environment, the study programme and the organisation. The challenges revolve mainly around the cooperation and integration of HE and VET. The paper concludes with an outlook on future DBR projects designing dual studies."}],"status":"public","_id":"48366","user_id":"81839","article_number":"24","article_type":"original","keyword":["Dual study programmes","Design challenges","Pedagogic development of HEIs","Literature review","Study programme development","DBR cycle"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2511-0667"]},"issue":"1","year":"2020","citation":{"apa":"Mordhorst, L., &#38; Gössling, B.

The key design principle of SMBO is a substitution of the true objective function by a surrogate, which is used to propose the point(s) to be evaluated next. SMBO algorithms are intrinsically modular, leaving the user with many important design choices. Significant research efforts go into understanding which settings perform best for which type of problems. Most works, however, focus on the choice of the model, the acquisition function, and the strategy used to optimize the latter. The choice of the initial sampling strategy, however, receives much less attention. Not surprisingly, quite diverging recommendations can be found in the literature. We analyze in this work how the size and the distribution of the initial sample influences the overall quality of the efficient global optimization (EGO) algorithm, a well-known SMBO approach. While, overall, small initial budgets using Halton sampling seem preferable, we also observe that the performance landscape is rather unstructured. We furthermore identify several situations in which EGO performs unfavorably against random sampling. Both observations indicate that an adaptive SMBO design could be beneficial, making SMBO an interesting test-bed for automated algorithm design.","lang":"eng"}],"date_created":"2023-11-14T15:58:53Z","publisher":"Association for Computing Machinery","title":"Initial Design Strategies and Their Effects on Sequential Model-Based Optimization: An Exploratory Case Study Based on BBOB","year":"2020"},{"date_updated":"2026-02-27T10:43:48Z","volume":50,"date_created":"2020-10-12T08:30:08Z","title":"Process design for the forming of semi-tubular self-piercing rivets made of high nitrogen steel","doi":"10.1016/j.promfg.2020.08.052","quality_controlled":"1","publication_status":"published","year":"2020","intvolume":"        50","page":"280-285","citation":{"ieee":"C.-M.

As a consequence of the resulting need for multi-material design, mechanical joining technologies become increasingly important. Mechanical joining allows for the combination of dissimilar materials, while thermic joining techniques reach their limits. Self-piercing riveting enables the joining of dissimilar materials by using semi-tubular rivets as mechanical fasteners. The rivet production, however, is costly and time-consuming, as the rivets generally have to be hardened, tempered and coated after forming, in order to achieve an adequate strength and corrosion resistance. A promising approach to improve the efficiency of the rivet manufacturing is the use of high-strength high nitrogen steel as rivet material because these additional process steps would not be necessary anymore. As a result of the comparatively high nitrogen content, such steels have various beneficial properties like higher strength, good ductility and improved corrosion resistance. By cold bulk forming of high nitrogen steels high-strength parts can be manufactured due to the strengthening which is caused by the high strain hardening. However, high tool loads thereby have to be expected and are a major challenge during the production process. Consequently, there is a need for appropriate forming strategies. This paper presents key aspects concerning the process design for the manufacturing of semi-tubular self-piercing rivets made of high-strength steel. The aim is to produce the rivets in several forming stages without intermediate heat treatment between the single stages. Due to the high strain hardening of the material, a two stage forming concept will be investigated. Cup-backward extrusion is chosen as the first process step in order to form the rivet shank without forming the rivet foot. Thus, the strain hardening effects in the area of the rivet foot are minimized and the tool loads during the following process step can be reduced. During the second and final forming stage the detailed geometry of the rivet foot and the rivet head is formed. In this context, the effect of different variations, for example concerning the final geometry of the rivet foot, on the tool load is investigated using multistage numerical analysis. Furthermore, the influence of the process temperature on occurring stresses is analysed. Based on the results of the investigations, an adequate forming strategy and a tool concept for the manufacturing of semi-tubular self-piercing rivets made of high-strength steel are presented.","lang":"eng"}],"editor":[{"last_name":"Kuball","full_name":"Kuball, Clara-Maria","first_name":"Clara-Maria"},{"full_name":"Uhe, Benedikt","id":"38131","last_name":"Uhe","first_name":"Benedikt"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson"},{"last_name":"Merklein","full_name":"Merklein, Marion","first_name":"Marion"}],"status":"public"},{"department":[{"_id":"157"}],"user_id":"53912","_id":"19973","language":[{"iso":"eng"}],"keyword":["Self-piercing riveting","Joining technology","Rivet geometry","Multi-material design","High-strength steel","Aluminium"],"article_type":"original","publication":"Production Engineering","type":"journal_article","status":"public","abstract":[{"text":"As a result of lightweight design, increased use is being made of high-strength steel and aluminium in car bodies.

In the present investigation, an improved rivet geometry is developed, which permits the reliable joining of two material combinations that could only be joined by two different rivet geometries up until now. Material combination 1 consists of high-strength steel on both sides, while material combination 2 comprises aluminium on the punch side and high-strength steel on the die side. The material flow and the stress and strain conditions prevailing during the joining process are analysed by means of numerical simulation. The rivet geometry is then improved step-by-step on the basis of this analysis. Finally, the improved rivet geometry is manufactured and the findings of the investigation are verified in experimental joining tests.","lang":"eng"}],"volume":14,"date_created":"2020-10-12T08:14:13Z","author":[{"last_name":"Uhe","full_name":"Uhe, Benedikt","id":"38131","first_name":"Benedikt"},{"first_name":"Clara-Maria","full_name":"Kuball, Clara-Maria","last_name":"Kuball"},{"first_name":"Marion","last_name":"Merklein","full_name":"Merklein, Marion"},{"first_name":"Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","id":"32056","full_name":"Meschut, Gerson"}],"date_updated":"2026-02-27T10:41:55Z","doi":"10.1007/s11740-020-00973-w","title":"Improvement of a rivet geometry for the self-piercing riveting of high-strength steel and multi-material joints","quality_controlled":"1","publication_status":"published","intvolume":"        14","page":"417-423","citation":{"bibtex":"@article{Uhe_Kuball_Merklein_Meschut_2020, title={Improvement of a rivet geometry for the self-piercing riveting of high-strength steel and multi-material joints}, volume={14}, DOI={<a href=\"https://doi.org/10.1007/s11740-020-00973-w\">10.1007/s11740-020-00973-w</a>}, journal={Production Engineering}, author={Uhe, Benedikt and Kuball, Clara-Maria and Merklein, Marion and Meschut, Gerson}, year={2020}, pages={417–423} }","short":"B.
