1 The AES has launched a new opportunity to recognize student members who author technical papers. The Student Paper Award Competition is based on the preprint manuscripts accepted for the AES convention. Twenty-seven student-authored papers were nominated. The excellent quality of the submissions has made the selection process both challenging and(More)
The level of automation in factories and plants, and the need for their fast design and customization, increases steadily. These systems are often designed with various means, and controlled by heterogeneous embedded hard- and software. These circumstances raise the problem complexity and the time to be invested. The state-of-the art and the trends in(More)
The standard IEC 61499 claims to be a standard for a distributed control environment consisting of a set of heterogeneous control devices from different vendors. Previous research work on the implementation of IEC 61499 pointed out so-called loopholes in the definitions of the standard resulting in different execution behaviour on different control devices.(More)
The semantic loopholes of the standard IEC 61499 have been pointed out in different recent publications with focus on some details. This paper investigates especially on the execution models for composite function blocks and subapplications. Of course this is closely related to the execution of basic function blocks and function block networks. Therefore,(More)
This paper presents a new execution model and a concrete application of the IEC 61499 standard in the larger context of a currently running European project, which seeks to preserve shoe-manufacturing activities in Europe through the development of advanced production systems. The present work summarizes an analysis of current practices and research(More)
The aim of this paper is to describe a research roadmap for a multi-domain model-driven embedded systems design approach and the corresponding meta-model which is applicable to the domain of complex Industrial Automation and Control Systems (IACS). The special requirements of the industrial automation sector are taken into account by this novel approach,(More)
Support for evolutionary design approaches is not a very much investigated topic in the automation domain. Advanced facilities for semantic validation, refactoring and model transformations, which are necessary for rapid prototyping of control applications, are seldom found in design tools. Implementing such facilities is even more difficult when using the(More)
The increasing complexity of automation systems and the great variety of platforms and languages favor an abstract approach to the design of control applications,approach to the design of control applications, which should also integrate mechanical, electrical and process information. A European project tackled this problem, and for achieving the goal of(More)
The IEC 61499 standard has been recently adopted to promote a more flexible development process in the control and automation domain. The standard mainly deals with modeling issues leaving a lot of model execution details open. Different research groups are already working for the development of execution environments for the defined component model,(More)
To optimize real-time stream-processing applications for chip-level multi processors, several challenges have to be met. Poor scalability and poor internal data pressure may result from serial dependencies within or between the algorithms. Load imbalances introduced by the parallel-processing hardware and execution environment may also limit performance. To(More)
