The Media Oriented Systems Transport (MOST) network, the current de-facto standard for in-vehicle multimedia and infotainment, does not provide support for the stream priority and serves bandwidth allocation requests based on their arrival order, irrespective of the stream importance. This work proposes a novel bandwidth allocation approach for multimedia streams on MOST150 networks that introduces...
An RFID reader collecting neural data from implanted electrodes of an electro-corticography ECoG system is proposed. The system also is able to power an implant using a class E power amplifier (PA) while it receives data by an asynchronous demodulation. A standard 65nm CMOS TSMC technology is used. Simulations reveal an average power consumption of the overall system of 19 mW with on a 1.2V supply...
This paper contributes a framework that helps to fulfill the requirements of the standards DIN EN 16247 and ISO 50001 by combining (i) a synchronized data acquisition, (ii) data integration, (iii) learning of normal behavior models and (iv) a implementation of an anomaly detection as prototype. Both standards require a reliable data acquisition and energy consumption analysis for implementing a certified...
The complexity of modern embedded systems is ever increasing and the selection of target platforms is shifting from homogeneous to more heterogeneous and powerful configurations. In our previous works, we exploited the power of model-driven techniques to deal with such complexity by enabling the automatic generation of full-fledged functional code from UML models enriched with ALF action code. Nevertheless,...
Flexible Time-Triggered communication (FTT) allows a distributed embedded system (DES) to adapt to changing real-time requirements at runtime. This facilitates the continuous operation of the DES under dynamic environments that change over time. However, for continuous operation, high reliability in the nodes of the DES is also crucial. This can be achieved using node replication, as long as failure...
Large industrial environments are inherently complex systems to be monitored and controlled, given the presence of vehicles, people and industrial plants. In a context dominated by strict regulations for workplace safety, systems for monitoring and preventing workplace risks can have a particular importance. This paper describes the work in progress on designing and implementing an RFID-based sensor...
This paper describes an application that was developed for the semantic alarm correlation with the objective of making inferences about alarm correlation. In order to do that we structured the knowledge about industrial processes through the development of a domain ontology, allowing better development of advanced functionality linked to its operation, alarm management, and anomaly diagnosis. The...
ROS (Robot Operating System) is a framework for the development of robotic applications widely used throughout research community due to its modular architecture and distributed nature. Using this framework a robot application consists of several nodes that exchange data over a common middle-ware. Programming new nodes is done by using a ROS API (application programming interface) on one of the available...
It is well known that modern factory automation applications must be able to adapt to changes in the production requirements. Since most manufacturing applications are distributed, it may be necessary to reconfigure several devices simultaneously. Unfortunately, dealing with reconfiguration is a complex issue for the developers of the applications, especially when applications are time-sensitive or...
This paper presents a model-based design approach for description of mechatronic systems using System Modeling Language (SysML) in order to facilitate modification and customization of existing intelligent mechatronic components and their use in new applications. This approach enables re-use and integration of the existing mechatronic software components to meet system design requirements and minimize...
In this paper, a nanorobotic system containing a custom-made nanohandling robot, atomic force microscope, scanning electron microscope and focused ion beam is presented. The nanorobotic atomic force microscope system facilitates the analysis of nanostructured surfaces as well as the handling of nanoobjects. Furthermore, a gas injection system is available that enables particle beam-based structuring...
Injection molding is a very complicated process to monitor and control. With its high complexity and many process parameters, the optimization of these systems is a very challenging problem. To meet the requirements and costs demanded by the market, there has been an intense development and research with the aim to maintain the process under control. This paper outlines the latest advances in algorithms...
Automation systems comprise often huge and complex communication networks which save resources such as energy, time, capital and effort for humans. Design of automation systems is often a highly complex problem. For creation of optimal building automation system design, if component variety on the market is considered, there emerge many trade-off design solutions. In our previous work high quality...
Standards conformance and integrated development are key features of modern automation systems. This paper introduces an integrated development environment (IDE) that enables high-speed EtherCAT communication and standardized motion programming. On the basis of our previous work, we extended and customized open-source software components to provide a completely open architecture IDE, that is compliant...
Following the increasing complexity of production systems and increasing consideration of engineering costs engineering processes have to be efficient and should generate fault free results. As different engineering disciplines, engineering tools and humans are involved in the engineering process information exchange is a crucial factor calling for standardized and lossless technological solutions...
This paper provides a strategy for supervising the motion of some mobile robots that evolve in the same environment. Some regions of the environment are assumed to have a limited capacity in terms of the number of robots that can simultaneously occupy them, and a set of possible trajectories is available for each robot. The solution comprises the construction of a specific Petri net model for the...
The fuzzy rule sets, which have been derived from the hybrid neural network model, called the O-EGART-PR-FIS, is an integration of the Adaptive Resonance Theory (ART) into Generalized Regression Neural Network (GRNN), display substantial redundancy and low interpretability that leads to time-consuming prediction process. The O-EGART-PR-FIS approach can achieve the highest accuracy rate among all,...
A call graph of a program represents the information which executable program element calls which other executable program elements. Based on the call graph, points-to sets can be computed, which represent the memory locations a reference variable can possibly point to. Call graph and points-to sets provide important information for static program analysis. This is especially true for PLC programs...
The general class of linear singular neutral multi delay systems is introduced. The controller is of the general proportional multi delay measurement output feedback type. For the case of regularizable linear singular multi delay systems the design problem of Exact Model Matching (EMM) is solved under the assumption that the ideal model is left invertible. The necessary and sufficient conditions for...
For several years many applications are using wireless communication in industrial automation, although wireless solutions (WS) are not yet fully integrated into the life cycle (LC) process of automation systems. Since several wireless technologies are candidates to fulfill given automation communication requirements, it is almost impossible for automation engineers to select the appropriate solution,...
