Building Advanced Mechatronic Systems

Abstract
Mechatronics is the engineering discipline concerned with the construction of systems incorporating mechanical, electronical and information technology components. Typical examples of mechatronic systems are automotive applications, e.g. advanced braking systems, fly/steer-by-wire or active suspension techniques, but also DVD-players or washing machines. Mechatronic systems are characterised by a combination of basic mechanical devices with a processing unit monitoring and controlling it via a number of actuators and sensors. This leads to massive improvements in product performance and flexibility. The introduction of mechatronics as a tight integration of mechanical, electronical and information-driven units allowed for turning conventionally designed mechanical components into smart devices.
Today we see the first steps in the emergence of the next generation of mechatronic systems. While ''intelligence'' in the behaviour has so far always been achieved by gathering information (and reacting to it) from the one single machine, the usage and retrieval of information in the future will be characterised by an exchange of information between different machines. This can for instance already be seen in the automotive and rail domain:
Intelligent lighting systems combine information about their environment obtained from their own sensors with those collected by other cars. In the Paderborn rail system shuttles autonomously form convoys as to reduce air resistance and optimise energy consumption.
In the talk we survey current state of the art in the development of mechatronic systems from a software engineering point of view. Based on identified weaknesses of existing approaches we present our own approach called Mechatronic UML. Mechatronic UML supports model-driven development of mechatronic systems addressing complex coordination between system components under hard real-time constraints and reconfiguration of control algorithms at runtime to adjust the system behaviour to changing system goals as well as target platform specific code generation. Modelling is based on a syntactically and semantically rigorously defined and partially refined subset of UML. It uses a slightly refined version of component diagrams, coordination patterns, and a refined version of state charts including the notion of time which are called Real time state charts. Verification of safety properties is based on a special kind of compositional model checking to make it scalable. Model checking exploits an underlying unifying semantics which is formally defined using graph transformation systems. The last part of the talk is devoted to pointing out future developments and research challenges which we believe characterise advanced mechatronic systems of the future.

ELI-ALPS - The Ultrafast Challenges in Hungary
Gábor Szabó
University of Szeged, Hungary
Abstract
The ELI – Extreme Light Infrastructure – or as it is commonly referred to: the SUPERLASER will be one of the large research facilities of the European Union. ELI will be built with a joint international effort to form an integrated infrastructure comprised of three branches. The ELI Beamline Facility (Prague, Czech Republic) will mainly focus on particle acceleration and X-ray generation, while the ELI Nuclear Physics Facility (Magurele, Romania) will be dealing with laser-based nuclear physics as well as high field physics. In the talk we introduce the ELI Attosecond Light Pulse Source (ELI-ALPS) to be built in Szeged, Hungary.
The primary mission of the ELI-ALPS Research Infrastructure is to provide the international scientific community with a broad range of ultrafast light sources, especially with coherent XUV and X-ray radiation, including single attosecond pulses. Thanks to this combination of parameters never achieved before, energetic attosecond X-ray pulses of ELI-ALPS will enable recording freeze-frame images of the dynamical electronic-structural behaviour of complex atomic, molecular and condensed matter systems, with attosecond-picometer resolution. The secondary purpose is to contribute to the scientific and technological development towards generating 200 PW pulses, being the ultimate goal of the ELI project. ELI-ALPS will be operated also as a user facility and hence serve basic and applied research in physical, chemical, material and biomedical sciences as well as industrial applications.
The Facility will be built by the end of 2015 from a budget exceeding 240M€. The building and the IT infrastructure, from high speed internal networking, remote controlled system alignment, targetry and data aquisition through laser and radiation safety tools until security systems, will challenge the state of the art of similar research facilities.

Software Architecture: Reflections on an Evolving Discipline

Abstract
Software Architecture emerged in the 1990’s as an important sub-field of software engineering. While good architectural design had long been recognized as critical to the success of any complex software system, before then the practice of architecting had relied largely on ad hoc, uncodified, and idiosyncratic techniques and knowledge. By the 2000’s the field had matured to the point where there were widely-recognized taxonomies of architectural patterns, techniques for formally representing and analyzing architectures, methods for reviewing an architectural design, widespread adoption of architectural product lines and composition frameworks, and techniques for ensuring conformance between an architecture and an implementation of it. In this talk we reflect on the key enablers of a discipline of software architecture that led to these advances, the central ideas that form its core, and its enduring principles that continue to shape the field of software engineering. We consider both the important concepts on which it builds, as well as those that have built on top of it. Finally, we examine some of the important new trends and challenges that are likely to have an impact on how software architecture will evolve in the future.
