When we are confronted with performance issues in a general-purpose language, like Java, it is a given to us that we have various tools and techniques at our disposal to help us. But is such support also needed when using model transformation languages? To address this question, we conducted a quantitative online survey ...

This work has been published as a full paper at SEAMS'21. In the context of self-adaptive systems, there are situations where human involvement in the adaptation process is beneficial or even necessary. For such ''human-in-the-loop'' adaptive systems, two major challenges, namely transparency, and controllability must ...

In this talk, we present our contribution ''Orthogonal Uncertainty Modeling in the Engineering of Cyber-Physical Systems'' published in IEEE Transactions on Automation Science and Engineering in July 2020 [Ba20]. We have proposed a modeling language for ''Orthogonal Uncertainty Models'' (OUMs). OUMs constitute a dedicated, ...

This work has been published as a full paper at the MODELS'21 conference. Through collaborative modeling, end-users and experts can create a shared understanding of a system representation. While the Unified Modeling Language (UML) is one of the major conceptual modeling languages in object-oriented software engineering, ...

Isolation, autonomy, and loose coupling are critical success factors of microservice architectures, but unfortunately, systems tend to become strongly coupled over time and sometimes even exhibiting cyclic communication chains. These cycles can even manifest on a conceptual or domain level, making them hard to track for ...

We examine how the behavior of software developers changes in response to removing gamification elements from GitHub, an online platform for collaborative programming. We find that the unannounced removal of daily activity streak counters from the user profile pages was followed by significant changes in behavior. ...

This workshop focuses on Software Engineering in Cyber-Physical Production Systems (SECPPS). SECPPS is an interactive workshop opened by keynotes and lightning talks, followed by project showcase presentations, and concluded by extensive discussions in break-out groups. The main output of SECPPS 2022 is an updated research ...

Model transformations are one key concept of model-driven engineering, and model transformation languages (MTLs) emerged with its popularity about 15 to 20 years ago. MTLs claim to ease model transformation development by abstracting from recurring transformation aspects and hiding complex semantics behind simple and ...

In this work, we report about recent research on Feature Trace Recording, originally published at the Joint European Software Engineering Conference and Symposium on the Foundations of Software Engineering (ESEC/FSE) 2021. Tracing requirements to their implementation is crucial to all stakeholders of a software development ...

This summary refers to the paper ''Model-based resource analysis and synthesis of service-oriented automotive software architectures.'' This paper has been published in the Journal on Software and Systems Modeling (SoSyM) in September 2021. Context: One drawback of today's automotive software architectures is their strong ...
