Multi-core real-time systems process tasks in parallel on two or more cores. Tasks in our contribution may preempt other tasks, block tasks with semaphores to access global shared resources, or migrate to another core. The depicted task behavior is random. The shape of collected response times of a task within a processing time is multimodal. Extreme Value approaches need unimodal response time distributions to estimate the Worst Case Response Time of tasks. The new proposed method derives a set of three task set shapes from the source task set. It is used to minimize the uncertainty of random task behavior by maximizing the coverage of possible Worst Case Response Times. The case study evaluates the new proposed estimation method by the use of dynamically generated random tasks with varying task properties.}, language = {en} } @article{FuhrmannMottok, author = {Fuhrmann, Thomas and Mottok, J{\"u}rgen}, title = {Ethical, intercultural and professional impulses integrated into a transmission systems lecture}, series = {2017 IEEE Global Engineering Education Conference (EDUCON), 25-28 April 2017, Athens, Greece}, journal = {2017 IEEE Global Engineering Education Conference (EDUCON), 25-28 April 2017, Athens, Greece}, publisher = {IEEE}, doi = {10.1109/EDUCON.2017.7942829}, pages = {92 -- 95}, abstract = {In the sixth semester of the bachelor study course "Electrical Engineering and Information Technology", a lecture "Transmission Systems" is given. It explains basic principles, circuits and systems of electrical and optical transmission systems. Short intellectual impulses, which address professional, intercultural and ethical issues of engineers' working life are integrated into this regular lecture. In each lecture unit, an impulse with one specific topic is given approximately in the middle of the lecture hour. An evaluation was done at the end of the semester, which shows that most of the students remember the discussed topics and state high interest due to high importance for their professional life. Due to these encouraging results, this concept will be developed further.}, language = {en} } @inproceedings{HaasMottok, author = {Haas, Kerstin and Mottok, J{\"u}rgen}, title = {Evaluation of the Research-oriented Learning Environment in a Research Association}, series = {9th International Conference on Education and New Learning Technologies, EDULEARN2017, 3-5 July 2017, Barcelona, Spain, Proceedings}, booktitle = {9th International Conference on Education and New Learning Technologies, EDULEARN2017, 3-5 July 2017, Barcelona, Spain, Proceedings}, doi = {10.21125/edulearn.2017.0872}, language = {en} } @inproceedings{HaasMottok, author = {Haas, Kerstin and Mottok, J{\"u}rgen}, title = {Research oriented learning in a research association - Evaluated in a maturity model}, series = {Teaching and Learning in a Digital World, Proceedings of the 20th International Conference on Interactive Collaborative Learning (ICL), September 27 to 29, 2017, in Budapest, Hungary - Volume 1}, booktitle = {Teaching and Learning in a Digital World, Proceedings of the 20th International Conference on Interactive Collaborative Learning (ICL), September 27 to 29, 2017, in Budapest, Hungary - Volume 1}, doi = {10.1007/978-3-319-73210-7_81}, pages = {695 -- 701}, abstract = {Research-oriented learning provides students the opportunity to develop their research competences by experiencing research practice, this often happens in the surrounding of research associations with different universities and companies. This paper introduces a two-step approach to evaluate the research-oriented learning within a research association. First we conduct the evaluation of the research environment with the instrument of the adapted Collaboration Maturity Model (Col-MM) to see whether the collaboration network and the management is able to support the students in their learning process. Additionally, we take into account the evaluation of the students' research competence. This approach targets the assessment of the starting conditions of the students and to compare their performance level until the end of the research association project phase. These two evaluation phases provide the potential to create an ideal research environment and consequently enable the students to develop and improve their research competence.}, language = {en} } @inproceedings{SailerDeubzerLuettgenetal., author = {Sailer, Andreas and Deubzer, Michael and L{\"u}ttgen, Gerald and Mottok, J{\"u}rgen}, title = {Comparing Trace Recordings of Automotive Realtime Software}, series = {RTNS '17: Proceedings of the 25th International Conference on Real-Time Networks and Systems, Grenoble, France, IEEE}, booktitle = {RTNS '17: Proceedings of the 25th International Conference on Real-Time Networks and Systems, Grenoble, France, IEEE}, doi = {10.1145/3139258.3139265}, pages = {118 -- 127}, abstract = {The process of engineering models of existing real-time system components is often difficult and time consuming, especially when legacy code has to be re-used or information about the exact timing behaviour is needed. In order to tackle this reverse engineering problem, we have developed the tool CoreTAna. CoreTAna derives an AUTOSAR compliant model of a real-time system by conducting dynamic analysis using trace recordings. Motivated by the challenge of assessing the quality of reverse engineered models of real-time software, we present a novel mathematical measure for comparing trace recordings from embedded real-time systems regarding their temporal behaviour. We also introduce a benchmark framework based on this measure, for evaluating reverse engineering tools such as CoreTAna. This considers common system architectures and also includes randomly generated systems and three systems of industrial automotive projects. Finally, an industrial case study demonstrates other use cases of our measure, such as impact analysis.}, language = {en} } @inproceedings{HauserReissNivalaetal., author = {Hauser, Florian and Reiß, Markus and Nivala, Markus and Mottok, J{\"u}rgen and Gruber, Hans}, title = {Eye tracking applied: Visual expertise in code reviews}, series = {9th International Conference on Education and New Learning Technologies, EDULEARN17, 3-5 July, 2017, Barcelona, Spain, Proceedings}, booktitle = {9th International Conference on Education and New Learning Technologies, EDULEARN17, 3-5 July, 2017, Barcelona, Spain, Proceedings}, doi = {10.21125/edulearn.2017.1084}, pages = {379 -- 389}, language = {en} } @inproceedings{NivalaHauserJossbergeretal., author = {Nivala, Markus and Hauser, Florian and Jossberger, Helen and Reiß, Markus and Mottok, J{\"u}rgen and Gruber, Hans}, title = {Detecting errors in program flow diagrams: Comparing novices and advanced programmers}, series = {EARLI Biennial Conference 2017, 17th European Association for Research on Learning and Instruction, 29 August - 2 September, 2017 - University of Tampere, Finland}, booktitle = {EARLI Biennial Conference 2017, 17th European Association for Research on Learning and Instruction, 29 August - 2 September, 2017 - University of Tampere, Finland}, language = {en} } @inproceedings{SoskaReuterHauseretal., author = {Soska, Alexander and Reuter, Rebecca and Hauser, Florian and Reiß, Markus and Mottok, J{\"u}rgen}, title = {Scaffolding in der Lehre von Design Pattern.
