This paper presents a framework for real-time database design that is able to support real-time database requirements such as time-constrained data and time-constrained transactions. It is based upon a real-timeobject-oriented data model in which each object encapsulates time-constrained data, time-constrained methods and concurrency control mechanisms. Our framework is composed of an UML profile for real-time database, a translator to object-relational model, and an UML CASE Tool.

As the automotive industry moves towards reduced physical prototyping it is becoming more dependent on distributed simulations. However, the current technologies do not fully enable real-timedistributed simulations which involve both virtual and physical components. This paper considers the current approaches to real-timedistributed simulation and proposes the use of service-orientation. The highlights and current shortfalls of current research in real-timeservice orientation are then identified. Finally a key area of research is focused upon requiring a fundamental change of the understanding of quality of service and capability that is necessary to enable dependable real-timeservice orientated architectures.

Java is a programming technology which has been extended in order to provide the timeliness required by real-time systems (e.g., RTSJ). There are two RTSJ-based profiles: DRTSJ supporting distributedreal-time Java systems and SCJS supporting the development of programs that must be certified. However neither of them considers dynamics characteristics allowing the system to be adapted to the changing environment. distributed safety-critical systems that must provide continuous service (e.g., air-traffic control systems or enterprise and financial applications) require dynamic updates. Dynamic software modification is a useful capability because the application is able to update itself to fix bugs and add new features without requiring a stop and a restart. In this paper, we overview Java solutions considering real-time requirements in service-orientedcomponent models allowing dynamics updates (e.g., OSGi).
The increasing interest in the Internet of Things (IoT) has brought lots of opportunities and challenges to researchers. Cyber-space and physical world are more and more amalgamated by smart devices with networking ca...

This panel discusses two different approaches to overcome the embedded software crisis. On one hand, model-driven design is an approach to build software by using a hierarchy of models and automatic transformation between these models. Organic computing is building systems inspired by nature. A main purpose of this panel is to answer the question if these approaches are contradictory or can be combined in a synergetic way.

Autonomic Systems on Chip provision VLSI systems with the capabilities of self-organization, self-healing and self-optimization, thereby allowing them to adapt to their environment and improve their functionality through run-time learning. This paper presents our current status of work on autonomic SoC architectures, beginning with a robust, self-correcting processor data path architecture and progressing to reinforcement machine learning techniques for self-optimization and self-organization at run time. An outlook of our future work and upcoming challenges in regard to autonomic systems on chip is then presented as a basis for discussion at the SORT workshop, and with the organic computing community in general.
