Adaptable digital labs - motivation and vision of the CrossLab project. - In: IEEE Xplore digital library, ISSN 2473-2001, (2022), insges. 6 S.
The flexibility and performance of digital laboratory elements such as remote labs, VR/AR or simulations summarized under the term cross-reality labs (CrossLabs), can be seen with the development in last and has been proven under the pandemic situation. Even though the potential of cross-reality labs is obvious referring to availability and flexibility for the students, these didactic solutions remain isolated at universities as well as for individual users. The implementations are mostly so rigid that the individual didactic objectives are not interchangeable between different universities and disciplines, hence there is a lack of interoperability. The CrossLab project seeks to design didactical, technical, and organizational solutions for open digital lab objects linking student-centered teaching and a cross-university learning environment. Of importance thereby is the fact that teaching is not adaptable to the digital laboratory, but the laboratories are adaptable to the requirements of the teaching-learning setting. The four project partners are working on a cross-type and cross-element mixture of diverse types of laboratories for cross-disciplinary use in a cross-universities settings. Thereby, the project leans on existing digital laboratories in various disciplines to create an open teaching and learning environment which can be adapted to the needs of students and to provide students with the skills necessary for future working scenarios.
On the development of a unified online laboratory framework. - In: Online engineering and society 4.0, (2022), S. 10-22
This work focuses on the requirements analysis of a modular framework to simplify developing and integrating new or existing remote experiments and laboratories. Besides this technical view, this paper also gives an organizational view on developing such a framework and managing the corresponding modules, which can also be developed by a third party. On a technical side, we provide the requirements to ultimately define the interface between different modules, enabling easy integration on different abstraction levels.The work's basis is the review of individual remote laboratories and existing systems of the past two decades and the author's collective experience. In the spirit of uniting the remote laboratory community, we will follow the IEEE 1876 standard wherever possible and extend it to make our vision of an easy to use, integrable, and extendable framework possible.

Simulating the printed circuit board assembly process for image generation. - In: 2020 IEEE 44th Annual Computers, Software, and Applications Conference, (2020), S. 245-254
The inspection of printed circuit board assemblies gradually incorporates deep-learning-based classifiers. However, such classifiers require a vast dataset. To our knowledge, such a dataset is not available. This paper proposes a method to simulate the assembly process aiming at generating such a dataset. The simulation of the solder joint shape forming during reflow and the creation of a photorealistic rendering of the assembled board have the most significant impact on the visual appearance of the results. Therefore, this paper focuses on the simulation of these steps. The calculation of the solder joint shape requires minimizing the surface tension energy. For this, the algorithm discretizes the energy equations over a heightmap. The proposed software architecture for the simulation is highly extendable and facilitate future development. Experiments with the simulation of solder joints of a chip resistor show a remarkable similarity to real images from an automatic optical inspection machine.
