To reduce this effort, we have developed a widely automated method for deriving test plans from requirements that are expressed in natural language. It consists of three stages: annotation, clustering, and test plan specification. The general idea is to exploit redundancies and implicit relationships in requirements specifications. Multi-viewpoint techniques based on RM-ODP (Reference Model for Open Distributed Processing) are employed for specifying the requirements. We then use linguistic analysis techniques, requirements clustering algorithms, and pattern-based requirements collection to reduce the total effort of testing against the requirements specification. In particular, we use linguistic analysis for extracting and annotating the actor, process and object of a requirements statement. During clustering, a similarity function is computed as a measure for the overlap of requirements. In the test plan specification stage, our approach provides capabilities for semi-automatically deriving test plans and acceptance criteria from the clustered informal textual requirements. Two patterns are applied to compute a suitable order of test activities. The generated test plans consist of a sequence of test steps and asserts that are executed or checked in the given order. We also present the supporting prototype tool TORC, which is available open source. For the evaluation of the approach, we have conducted a case study in the field of acceptance testing of a national electronic identification system. In summary, we report on lessons learned how linguistic analysis and clustering techniques can help testers in understanding the relations between requirements and for improving test planning."}],"volume":19,"date_created":"2019-01-31T13:00:53Z","status":"public","publication":"Software Quality Journal","author":[{"first_name":"Baris","full_name":"Güldali, Baris","last_name":"Güldali"},{"last_name":"Funke","first_name":"Holger","full_name":"Funke, Holger"},{"full_name":"Sauer, Stefan","first_name":"Stefan","id":"447","last_name":"Sauer"},{"last_name":"Engels","id":"107","first_name":"Gregor","full_name":"Engels, Gregor"}],"publisher":"Springer Nature","issue":"4","intvolume":" 19","_id":"7354","page":"771-799","type":"journal_article","year":"2011","citation":{"bibtex":"@article{Güldali_Funke_Sauer_Engels_2011, title={TORC: test plan optimization by requirements clustering}, volume={19}, DOI={10.1007/s11219-011-9149-4}, number={4}, journal={Software Quality Journal}, publisher={Springer Nature}, author={Güldali, Baris and Funke, Holger and Sauer, Stefan and Engels, Gregor}, year={2011}, pages={771–799} }","mla":"Güldali, Baris, et al. “TORC: Test Plan Optimization by Requirements Clustering.” Software Quality Journal, vol. 19, no. 4, Springer Nature, 2011, pp. 771–99, doi:10.1007/s11219-011-9149-4.","chicago":"Güldali, Baris, Holger Funke, Stefan Sauer, and Gregor Engels. “TORC: Test Plan Optimization by Requirements Clustering.” Software Quality Journal 19, no. 4 (2011): 771–99. https://doi.org/10.1007/s11219-011-9149-4.","ama":"Güldali B, Funke H, Sauer S, Engels G.

A DMM specification consists of a runtime metamodel and operational rules which describe how instances of the runtime metamodel change over time. A known deficiency of the DMM approach is that it does not support the refinement of a DMM specification, e.g., in the case of defining the semantics for a refined and extended domain-specific language (DSL). Up to now, DMM specifications could only be reused by adding or removing DMM rules. In this paper, we enhance DMM such that DMM rules can override other DMM rules, similar to a method being overridden in a subclass, and we show how rule overriding can be realized with the graph transformation tool GROOVE. We argue that rule overriding does not only have positive impact on reusability, but also improves the intuitive understandability of DMM semantics specifications."}],"language":[{"iso":"eng"}],"doi":"10.1016/j.jvlc.2010.12.005","date_updated":"2022-01-06T07:03:35Z","publication_identifier":{"issn":["1045-926X"]},"publication_status":"published","department":[{"_id":"66"}],"title":"Using rule overriding to improve reusability and understandability of Dynamic Meta Modeling specifications"},{"author":[{"full_name":"Kremer, H.-Hugo","first_name":"H.-Hugo","id":"15280","last_name":"Kremer"},{"first_name":"Petra","full_name":"Frehe, Petra","last_name":"Frehe","id":"5994"}],"department":[{"_id":"211"}],"publication":"Beilage Schule NRW","status":"public","date_created":"2019-02-04T13:34:00Z","user_id":"74378","title":"Individuelle Förderung - aber wie?

When a tester has spotted a performance error, the error is passed to the software developers to fix it. However, in component-based software development the tester has to do blame analysis first, i. e. the tester has to decide, which party is responsible to fix the error. If the error is a design or deployment issue, it can be assigned to the software architect or the system deployer. If the error is specific to a component, it needs to be assigned to the corresponding component developer. An accurate blame analysis is important, because wrong assignments of errors will cause a loss of time and money. Our approach aims at doing blame analysis for performance errors by comparing performance metrics obtained in performance testing and performance prediction. We use performance prediction values as expected values for individual components. For performance prediction we use the Palladio approach. By this means, our approach evaluates each component’s performance in a certain test case. If the component performs poorly, its component developer needs to fix the component or the architect replaces the component with a faster one. If no omponent performs poorly, we can deduce that there is a design or deployment issue and the architecture needs to be changed. In this paper, we present an exemplary blame analysis based on a web shop system. The example shows the feasibility of our approach.","lang":"eng"}],"title":"Palladio-based performance blame analysis","user_id":"52534"},{"title":"Semi-automatische Ableitung externer Anpassungsmechanismen für selbst-adaptive Systeme","user_id":"52534","place":"Bonn","date_created":"2019-03-08T09:38:16Z","status":"public","publication":"Proceedings of the Software Engineering 2011 (SE 2011), Karlsruhe (Germany)","department":[{"_id":"66"}],"author":[{"full_name":"Nagel, Benjamin ","first_name":"Benjamin ","last_name":"Nagel"}],"publisher":"Gesellschaft für Informatik (GI)","_id":"8472","date_updated":"2022-01-06T07:03:55Z","year":"2011","type":"conference","citation":{"short":"B.

The design of actuator based on a hollow piezoelectric cylinder mounted on a metal rod. The piezoceramic cylinder has a radial polarization and special configuration of the electrodes that cover inner and outer surface of the cylinder. The main advantage of actuator's design is that solid metallic rod operates as a part of inner electrode of the cylinder and a stator of actuator. The geometry of piezoelectric actuator was adopted to reach resonance of oscillations for the first longitudinal mode and the third flexural mode at same frequency. The actuator is designed to move positioned object through contact point which is located on the top of the rod. The optimal topology of electrodes was found to achieve longitudinal and flexural oscillations of the actuator in two perpendicular planes. Three degrees of freedom of the positioning object can be achieved and control of the system can be implemented by applying different excitation schemes and regimes. The numerical simulation and experimental study of piezoelectric actuator was performed. Impedance of actuator was analyzed under different excitation regimes.

Therefore, a neutralization was conducted in the powder washing process. Using this powder, a solid solution of (K,Na)NbO$_{3}$ceramics was synthesized.

Often these systems are applied in safety critical environments like in cars or aircrafts. This requires systems that function correctly and do not cause hazardous situations. However, random errors due to wear or external influences cannot be completely excluded. Consequently, we have to perform a hazard analysis for the system. Further, the union of four disciplines in one system requires the development and analysis of the system as a whole. We present a component-based hazard analysis that considers the entire mechatronic system including hardware, i.e. mechanical and electrical components, and software components. Our approach considers the physical properties of different types of flow in mechatronic systems. We have identified reusable patterns for the failure behavior which can be generated automatically. This reduces the effort for the developer. As cycles, e.g. control cycles, are an internal part of every mechatronic system our approach is able to handle cycles.

A multitude of wheel--rail contact models exists, however, traction--creepage curves obtained from measurements show quantitative and qualitative deviations. There are several phenomena which influence the traction--creepage characteristics: Mechanisms resulting from surface roughness, frictional heating or the presence of interfacial fluids can have a dominating influence on friction. In this paper, a new wheel--rail contact model, accounting for these influential parameters, will be presented. The presented model accounts for the interaction of an interfacial fluid model for combined boundary and mixed lubrication of rough surfaces with a wheel--rail contact model that additionally accounts for frictional heating. A quantitative comparison with measurements found in the literature is not conducted, since the exact conditions of the measurements are mostly unknown and parameters can easily be adjusted to fit the measurements. Emphasis is placed on the qualitative behavior of the model with respect to the measurements and good agreement is found. The dependence of the maximum traction coefficient on rolling velocity, surface roughness and normal load is studied under dry and water lubricated conditions."}],"user_id":"55222"},{"user_id":"55222","title":"High temperature tolerant transducer for Ultrasonic Assisted Hydrothermal Method","author":[{"full_name":"Isobe, Gaku","first_name":"Gaku","last_name":"Isobe"},{"last_name":"Bornmann","first_name":"Peter","full_name":"Bornmann, Peter"},{"id":"210","last_name":"Hemsel","full_name":"Hemsel, Tobias","first_name":"Tobias"},{"last_name":"Morita","full_name":"Morita, Takeshi","first_name":"Takeshi"}],"publisher":"Trans Tech Publ","quality_controlled":"1","department":[{"_id":"151"}],"publication":"Proceedings of Symposium on Ultrasonic Electronics","status":"public","date_created":"2019-05-20T13:09:04Z","volume":32,"_id":"9877","intvolume":" 32","date_updated":"2019-09-16T11:31:38Z","language":[{"iso":"eng"}],"type":"journal_article","year":"2011","citation":{"short":"G.

The calculations aim at a comprehensive,microscopic understanding of the\r\nprecipitation mechanism in the context of controversial discussions in the literature. For the quantum-mechanical\r\ntreatment, basic processes assumed in the precipitation process are calculated in feasible systems of small\r\nsize. The migration mechanism of a carbon \u0002100\u0003 interstitial and silicon \u000211 0\u0003 self-interstitial in otherwise\r\ndefect-free silicon are investigated using density functional theory calculations. The influence of a nearby\r\nvacancy, another carbon interstitial and a substitutional defect as well as a silicon self-interstitial has been\r\ninvestigated systematically. Interactions of various combinations of defects have been characterized including a\r\ncouple of selected migration pathways within these configurations. Most of the investigated pairs of defects tend\r\nto agglomerate allowing for a reduction in strain. The formation of structures involving strong carbon–carbon\r\nbonds turns out to be very unlikely. In contrast, substitutional carbon occurs in all probability. A long range\r\ncapture radius has been observed for pairs of interstitial carbon as well as interstitial carbon and vacancies. A\r\nrather small capture radius is predicted for substitutional carbon and silicon self-interstitials. Initial assumptions\r\nregarding the precipitation mechanism of silicon carbide in bulk silicon are established and conformability to\r\nexperimental findings is discussed. Furthermore, results of the accurate first-principles calculations on defects\r\nand carbon diffusion in silicon are compared to results of classical potential simulations revealing significant\r\nlimitations of the latter method. An approach to work around this problem is proposed. Finally, results of the\r\nclassical potential molecular dynamics simulations of large systems are examined, which reinforce previous\r\nassumptions and give further insight into basic processes involved in the silicon carbide transition."}],"volume":84,"status":"public","has_accepted_license":"1","date_created":"2018-08-27T13:17:45Z","publisher":"American Physical Society (APS)","author":[{"last_name":"Zirkelbach","full_name":"Zirkelbach, F.","first_name":"F."},{"last_name":"Stritzker","first_name":"B.","full_name":"Stritzker, B."},{"last_name":"Nordlund","first_name":"K.","full_name":"Nordlund, K."},{"last_name":"Lindner","id":"20797","first_name":"Jörg","full_name":"Lindner, Jörg"},{"full_name":"Schmidt, W.

Überwachung von Finanzinstitutionen nicht ausreichend ist. Sowohl in den USA als auch in der Europäischen Union wird deshalb intensiv über ein neues System zur Regulierung von Finanzinstituten nachgedacht. Es ist zwar offen-sichtlich, dass eine wesentliche Ursache der Finanzkrise in den USA die Ermunterung der Finanzinstitute durch den Staat zur Vergabe von Immobilienkrediten an nicht ausreichend solvente Konsumenten war. Die vorhandenen Regulierungsinstrumente konnten die Krise jedoch nicht verhindern bzw. ausreichen abmildern. Das vorliegende Papier setzt sich zum Ziel, die Vorschläge zur Reform der Bankenregulierung zu evaluieren und insbesondere auf ihre potenziellen Wirkungen im Hinblick auf den Wettbewerb im Bankensektor zu überprüfen.\r\n\r\nIm Zuge der Diskussion über mögliche Lösungen existieren verschiedenste Vorschläge, die von Änderungen in Rechnungslegungsvorschriften über die Neuordnung der nationalen bzw. internationalen Finanzaufsicht bis hin zu einer stärkeren Berücksichtigung systemischer Risiken gehen. Die Auswirkungen der Finanzkrise haben gezeigt, dass die Abkehr von herkömmlichen Rechnungslegungssystemen hin zu Regeln der internationalen Rechnungslegung unter dem Schlagwort „Fair Value Accounting“ durchaus Gefahren in sich bergen kann. Die Debatte dreht sich insbesondere um die Frage, ob die neuen Rechnungslegungsvorschriften maßgeblich dazu beitragen, das regulatorische Eigenkapital einer Bank in Boomphasen zu erhöhen und in konjunkturellen Schwächephasen dagegen zu senken. In der Literatur ist in Hinblick auf diese Frage bislang keine einhellige Auffassung zu identifizieren. Pellens et al. (2009) gelangen zu dem Ergebnis, dass bankenaufsichtsrechtliche Normen an das IFRS-Zahlenwerk gebunden sind und dies für regulatorische Entscheidungen als besonders kritisch zu sehen ist. Durch das Konzept des Fair-Value-Accounting wurde das regulatorische Eigenkapital im Zeitraum von 2003 bis 2007 systematisch erhöht, woraus ein gestiegener Kreditvergabespielraum resultierte. Demgegenüber kommen Laux und Leuz (2009) im Rahmen einer empirischen Studie anhand von Mikrodaten aus den USA zu dem Ergebnis, dass Fair-Value-Accounting nur zum geringen Teil zu den Problemen der US Banken beigetragen hat und es im Rahmen ihrer Studie keine Evidenz für wesentliche Effekte dieses Rechnungslegungsverfahrens auf die massiven Abschreibungen der US Banken gibt.\r\n\r\nBeide Studien betonen aber auch, dass weitere empirische Forschung notwendig ist, bevor diese Frage abschließend geklärt werden kann. Die Frage des adäquaten Rechnungslegungssystems zeigt, wie vielfältig die Ursachen der gegenwärtigen Finanzkrise sind und wie schwer tatsächliche kausale Effekte zu identifizieren sind. Im folgenden Abschnitt werden zunächst die ordnungspolitischen Rahmenbedingungen einer angemessenen Bankenregulierung dargestellt. Der dritte Abschnitt umfasst einen kurzen Überblick über den Verlauf der Finanzkrise. In Abschnitt 4 diskutieren wir die wesentlichen Vorschläge zur Optimierung der Regulierung von Finanzinstituten. Abschnitt 5 evaluiert diese Vorschläge auch aus einer wettbewerbsökonomischen Perspektive. Diese Perspektive ist aus unserer Sicht vor allen Dingen notwendig, weil eine großer Teil der Reformdebatte aus Sicht der Finanzmarktstabilität geführt wird und infolgedessen Wettbewerbseffekte vernachlässigt werden. Das Fazit in Abschnitt 6 fasst unsere Ergebnisse zusammen und gibt einen Ausblick auf weiteren Forschungsbedarf aus Sicht der Wettbewerbsökonomie."}]},{"publication_status":"published","volume":55,"status":"public","date_created":"2018-10-31T11:37:11Z","author":[{"first_name":"Carsten","full_name":"Homburg, Carsten","last_name":"Homburg"},{"full_name":"Lorenz, Michael","first_name":"Michael","last_name":"Lorenz"},{"first_name":"Sönke","full_name":"Sievers, Sönke","last_name":"Sievers"}],"publisher":"Springer","publication":"Controlling \\& Management","department":[{"_id":"275"}],"title":"Unternehmensbewertung in Deutschland: Verfahren, Finanzplanung und Kapitalkostenermittlung","user_id":"64756","citation":{"mla":"Homburg, Carsten, et al. “Unternehmensbewertung in Deutschland: Verfahren, Finanzplanung und Kapitalkostenermittlung.” Controlling \\& Management, vol. 55, no. 2, Springer, 2011, pp. 119–30.","bibtex":"@article{Homburg_Lorenz_Sievers_2011, title={Unternehmensbewertung in Deutschland: Verfahren, Finanzplanung und Kapitalkostenermittlung}, volume={55}, number={2}, journal={Controlling \\& Management}, publisher={Springer}, author={Homburg, Carsten and Lorenz, Michael and Sievers, Sönke}, year={2011}, pages={119–130} }","chicago":"Homburg, Carsten, Michael Lorenz, and Sönke Sievers. “Unternehmensbewertung in Deutschland: Verfahren, Finanzplanung und Kapitalkostenermittlung.” Controlling \\& Management 55, no. 2 (2011): 119–30.","apa":"Homburg, C., Lorenz, M., & Sievers, S.

We find that a broad array of financial instruments is used, covering straight equity, mezzanine and debt‐like securities. Based on the chosen financial securities’ upside potential and downside protection characteristics, we provide an explanation for the differing use of these securities. Our results show that investors’ deal experience, adverse selection risks and economic prospects in the public equity market influence the selection of financial securities.
