- Developing Cyber-Physical Systems requires methods and tools to support simulation and verification of hybrid (both continuous and discrete) models. The Acumen modeling and simulation language is an open source testbed for exploring the design space of what rigorous-but-practical next-generation tools can deliver to developers of Cyber-Physical Systems. Like verification tools, a design goal for Acumen is to provide rigorous results. Like simulation tools, it aims to be intuitive, practical, and scalable. However, it is far from evident whether these two goals can be achieved simultaneously.This paper explains the primary design goals for Acumen, the core challenges that must be addressed in order to achieve these goals, the "agile research method" taken by the project, the steps taken to realize these goals, the key lessons learned, and the emerging language design. © ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2016.

Developing a first course on cyber-physical systems

Journal article (peer-reviewed)abstract
- Effective and creative Cyber-Physical Systems (CPS) development requires expertise in disparate fields that have traditionally been taught in several distinct disciplines. At the same time, students seeking a CPS education generally come from diverse educational backgrounds. In this paper, we report on our recent experience of developing and teaching a course on CPS. The course addresses the following three questions: What are the core elements of CPS? How should these core concepts be integrated in the CPS design process? What types of modeling tools can assist in the design of Cyber-Physical Systems? Our experience with the first four offerings of the course has been positive overall. We also discuss the lessons we learned from some issues that were not handled well. All material including lecture notes and software used for the course are openly available online.

Conference paper (peer-reviewed)abstract
- The flipped classroom format involves swapping activities traditionally performed inside and outside the classroom. The expected effects from this swap include increased student engagement and peer-to-peer interaction in the classroom, as well as more flexible access to learning materials. Key criteria for successful outcomes from these effects include improved test scores and enhanced student satisfaction. Unfortunately, while many researchers have reported positive outcomes from the approach, some instructors can still encounter difficulties in reproducing this success.In this paper we report our experiences with flipping a first course on Cyber-Physical Systems at Halmstad University. The course is required for a Masters level program and is available as an elective for undergraduates. The focus of this report is on three separate editions of the course taught over three years. In the first year, lectures were recorded. In the second, the same instructor taught the course using the flipped format. In the third, new instructors taught it using the flipped classroom format.Our experience suggests that flipping a classroom can lead to improved student performance and satisfaction from the first edition. It can also enable new instructors to take over the course and perform at a level comparable to an experienced instructor. On the other hand, it also suggests that the format may require more effort to prepare for, and to teach, than the traditional format, and that a higher level of attention to detail is needed to execute it with positive outcomes. Thus, the format can be demanding for instructors. It is also the case that not all students preferred this format.
