Although marginalities may not affect the functionality of a circuit immediately after manufacturing, they can degrade into hard failures and must be screened out during manufacturing test to prevent early life failures. Furthermore, their evolution in the field must be proactively monitored by periodic tests before actual failures occur. In recent years small delay faults have gained increasing attention as possible indicators of marginal hardware. However, small delay faults on short paths may be undetectable even with advanced timing aware ATPG. Faster-than-at-speed test (FAST) can detect such hidden delay faults, but so far FAST has mainly been restricted to manufacturing test.}}, author = {{Kampmann, Matthias and A.

Second, we analyze two students' actual learning process based on Peircean semiotics. The analysis shows that the actual learning process diverges from the hypothesized learning process in that the students do not relate the different levels of the diagrams in a way that allows them to extrapolate the rule for the subtraction of negative numbers.

Accordingly, new types of applications take an advantage of the processing and flexibility provided by the wireless network. A common property between these applications is that the processing is not running on only one single node, but it is broken-down into smaller tasks that can run over multiple nodes, i.e., exploiting the in-network processing. We study a special variant of in-network processing, where the application is given by a graph; the processing tasks have predefined connections to be executed in a predefined sequence. The problem of embedding an application graph into a network is commonly known as Virtual Network Embedding (VNE). In this paper, we present a Genetic Algorithm (GA) solution to solve this wireless VNE problem, where we take into account the interference and multi-cast properties.

During the development process, many developers focus on the multitude of product functions but neglect the business model as an equally important part. As a result, developers often fail to meet customer needs, leading to unnecessary development costs and poor market penetration. This, in turn, raises the question of how we intertwine the business model and product functions during the development process to ensure a better alignment between the two. In this paper, we show this intertwined development by adapting the concept of Twin Peaks to the business model and product functions. Based on feature modeling as an abstraction layer, we introduce the concept of a Business Model Decision Line (BMDL) to structure the business model decisions and their relation to product functions structured in a Software Product Line (SPL). The basis of our feature models is the analysis of top listed applications in the app stores of Apple and Google. To create and modify both models, we provide an incremental feature structuring and iterative feature selection process. This combination of abstraction layer and development process supports third-party developers to build successful applications both from a business and a product perspective. }}, author = {{Gottschalk, Sebastian and Rittmeier, Florian and Engels, Gregor}}, booktitle = {{Software Business}}, editor = {{Hyrynsalmi, Sami and Suoranta, Mari and Nguyen-Duc, Anh and Tyrväinen, Pasi and Abrahamsson, Pekka}}, keywords = {{Intertwined Development, Twin Peaks, Feature Model, Business Model, Product Functions}}, location = {{ Jyväskylä}}, number = {{1}}, pages = {{192--207}}, publisher = {{Springer International Publishing}}, title = {{{Intertwined Development of Business Model and Product Functions for Mobile Applications: A Twin Peak Feature Modeling Approach}}}, doi = {{10.1007/978-3-030-33742-1_16}}, volume = {{370}}, year = {{2019}}, } @book{13139, editor = {{Rezat, Sebastian and Fan, Lianghuo and Hattermann, Mathias and Schumacher, Jan and Wuschke, Holger}}, location = {{Paderborn}}, pages = {{392}}, publisher = {{Universitätsbibliothek Paderborn}}, title = {{{Proceedings of the Third International Conference on Mathematics Textbook Research and Development: 16-19 September 2019 Paderborn, Germany}}}, doi = {{10.17619/UNIPB/1-768}}, year = {{2019}}, } @inproceedings{13140, author = {{Weidmann, Nils and Anjorin, Anthony and Stolte, Florian and Kraus, Florian}}, booktitle = {{Proceedings of the 12th International Conference on Graph Transformation, ICGT 2019, Held as Part of STAF 2019}}, editor = {{Guerra, Esther and Orejas, Fernando}}, location = {{Eindhoven, The Netherlands}}, pages = {{195--211}}, publisher = {{Springer}}, title = {{{From Pattern Invocation Networks to Rule Preconditions}}}, doi = {{10.1007/978-3-030-23611-3\_12}}, year = {{2019}}, } @inproceedings{13141, author = {{Weidmann, Nils and Anjorin, Anthony and Robrecht, Patrick and Varró, Gergely}}, booktitle = {{Proceedings of the 12th International Conference on Graph Transformation, ICGT 2019, Held as Part of STAF 2019}}, editor = {{Guerra, Esther and Orejas, Fernando}}, location = {{Eindhoven, The Netherlands}}, pages = {{131--140}}, publisher = {{Springer}}, title = {{{Incremental (Unidirectional) Model Transformation with eMoflon::IBeX}}}, doi = {{10.1007/978-3-030-23611-3\_8}}, year = {{2019}}, } @inproceedings{13142, author = {{Weidmann, Nils and Anjorin, Anthony and Fritsche, Lars and Varró, Gergely and Schürr, Andy and Leblebici, Erhan}}, booktitle = {{Proceedings of the 8th International Workshop on Bidirectional Transformations co-located with the Philadelphia Logic Week, Bx@PLW 2019}}, editor = {{Cheney, James and Ko, Hsiang-Shang}}, location = {{Philadelphia, PA, USA}}, pages = {{45--55}}, publisher = {{CEUR-WS.org}}, title = {{{Incremental Bidirectional Model Transformation with eMoflon::IBeX}}}, year = {{2019}}, } @article{13143, author = {{Claes, Leander and Hülskämper, Lars Moritz and Baumhögger, Elmar and Feldmann, Nadine and Chatwell, René Spencer and Vrabec, Jadran and Henning, Bernd}}, issn = {{2196-7113}}, journal = {{tm - Technisches Messen}}, pages = {{2--6}}, title = {{{Acoustic absorption measurement for the determination of the volume viscosity of pure fluids / Messverfahren für die akustischen Absorption zur Bestimmung der Volumenviskosität reiner Fluide}}}, doi = {{10.1515/teme-2019-0038}}, year = {{2019}}, } @inproceedings{13144, author = {{El Baff, Roxanne and Wachsmuth, Henning and Al-Khatib, Khalid and Stede, Manfred and Stein, Benno}}, booktitle = {{Proceedings of the 12th International Conference on Natural Language Generation}}, location = {{Tokyo, Japan}}, pages = {{54--64}}, publisher = {{Association for Computational Linguistics}}, title = {{{Computational Argumentation Synthesis as a Language Modeling Task}}}, year = {{2019}}, }
