Expertise

Prof. Weidlich is a professor at the Department of Computer Science, where he leads the Process-Driven Architectures research group. The goal of his team is to support and improve the design and the analysis of process-oriented information systems (POIS) and event-driven systems (ES). POIS are software systems that help to automate, monitor, and control processes. These systems are established in various domains, from logistics, through healthcare, to infrastructure monitoring. The team’s research focuses on formal methods for behavioural modelling and verification, event-driven approaches to monitor and control processes, as well as questions related to process-driven data integration. The group further works on techniques that optimise the run-time behaviour of event-driven systems. In particular, the evaluation of event queries over streams can be designed more efficiently once regularities within event streams have been detected. In 2016, Prof. Weidlich was named Junior Fellow of the German Informatics Society (Gesellschaft für Informatik, GI) and awarded with the Berlin Research Prize (Young Scientist) by the Governing Mayor of Berlin.

Expertise

Our daily life more and more depends on computational systems embedded in common appliances. Just think of advanced driver assistance systems in cars, medical devices, or indsutrial supervisory control and data acquisition systems. Since such systems also realise safety-critical tasks, it is all the more important to provide effective and efficient quality assurance for them. The specification, verification and testing theory group researches methods for model-based development and model checking, logical verification, and automated testing of safety-critical software. Prog. Schlingloff is chief scientist of the system quality center at Fraunhofer FOKUS, Berlin, and chairman of the boards of GFaI e.V. and ZeSys e.V.

Expertise

With his Computer Engineering research group, Prof. Scheuermann develops technologies for application-specific communication and computer systems that are efficient, secure, and reliable. The topics range from tailored communication protocols and application-specific digital circuits all the way to different aspects of online anonymity and privacy-preserving technologies. For instance, Prof. Scheuermann aims to interconnect automobiles to make best possible use of the available road network resources. Furthermore, he develops specialised circuitry for firewalls, so that within nanoseconds the firewall can decide what communication should be permitted. The research team models flow control and congestion control mechanisms for Internet anonymity systems, which for example allow political activists in totalitarian regimes to bypass Internet censorship. They design privacy compliant data collection algorithms, which grant detailed Internet traffic statistics without revealing information about individual users. His team’s expertise encompasses the set-up of wireless communication in between manufacturing machines in factories, so as to optimize the production process. In the field of warehouse logistics, Prof. Scheuermann combines measurements from various types of sensors to allow for a more accurate positioning of goods. In all fields of operation, tailored solutions for communication protocols and circuitry are necessary. The challenges are rooted in the particular application area: for instance, very fast or particularly reliable communication may be needed. Or data exchange is limited due to inherent technical limitations, yet the respective application must function reliably. It could be the case that IT security requirements need to be taken into account in new application fields where standard solutions fail. There may be a trade-off between data protection requirements or user privacy concerns, and communication requirements for data transmission. In all mentioned examples, it is necessary to look beyond common solution strategies and to keep the whole picture in mind. This systems perspective characterises the Computer Engineering group and its projects.

Expertise

Model-driven engineering raises the level of abstraction in software engineering by using models as primary development artifacts. In particular, domain-specific modelling languages can ease the transition between informally sketched requirements or designs and implementations by supporting high-level yet formal representations as a starting point for automation. Moreover, using a model-based development approach, critical system properties can be analyzed, validated and verified even before the system is actually built. Model-driven development thus leads to an increase in both productivity and quality. To some extent, model-driven engineering has made its way into industrial practice, most notably for the development of embedded systems in various domains. However, model-driven engineering does not suffice to successfully manage all challenges of modern software engineering, and actually creates new problems. Research conducted at the Chair of Model-driven Software Engineering is particularly driven by relevant challenges and problems arising from the adoption of the model-driven engineering paradigm in industrial practice.

Expertise Many IT systems are (for good reasons) technologically, administratively, or spatially seperate. It is the goal of middleware to integrate these systems, without merging them too itricately. Experience shows that this is not a trivial task. The chair of Systems Architecture investigates key issues that come up repeatedly: reliability/dependability, data security (and privacy), consitency of replicated data, performance and scalability. Autonomous subsystems should be able to auto-configurate but also support coordination by an external operator. Currently, home automation is our premier application domain for studying the aforementioned research questions and to evaluate proposed solutions in practice.
