Over the last decade, efforts from industries and research communities have been made in addressing the security of Supervisory Control and Data Acquisition (SCADA) systems. However, the SCADA security deployed for critical infrastructures is still a challenging issue today. This paper gives an overview of the complexity of SCADA security. Products and applications in control network security are reviewed. Furthermore, new developments in SCADA security, especially the trend in technical and theoretical studies are presented. Some important topics on SCADA security are identified and highlighted and this can be served as the guide for future works in this area.

Compared with relying on the efforts of various enterprises collaborating on product lifecycle activities, such as coordination, communication and control, the ability to effectively share product information and knowledge is more important. Therefore, how to best integrate such heterogeneous product knowledge distributed among various cooperating enterprises has become an extremely important knowledge management subjects associated with collaborative product lifecycle. This study develops a novel mechanism for integrating ontology-based product lifecycle knowledge to effectively integrate the heterogeneous product knowledge distributed among different enterprises during a productpsilas lifecycle, thereby facilitating sharing of this product knowledge.

Based on hierarchical-detection model, combined with the existing fault isolation strategies and the entropy theory, the essential of fault isolation process is expounded in this paper. It is concluded that the diagnostic strategies optimizing process is a dynamic test choice process, in order to get optimized fault isolation strategies, dynamic system entropy reduction should be considered, which is consists of failure candidates components variation and test selection. Then, based on this, a dynamic-entropy algorithm for the fault isolation is proposed. By the examination and analysis, the method is simple and could perform effective and fast fault isolation.

This paper deals with the temporal verification and assignment into the execution environment of reconfigurable control systems following the component based international industrial standard IEC61499. A function block (denoted by FB) is an event triggered component owning data and a reconfigurable control application is specified by different FB networks such as each one has to be automatically loaded in memory when a particular reconfiguration scenario is followed. To verify the whole temporal behavior of the system, we check the feasibility of each FB network corresponding to a possible reconfiguration scenario by exploring reachability graphs which will be transformed into OS tasks of the execution environment. Therefore, the reconfigurable system is assigned into different sets of OS tasks such as each set corresponds to a particular reconfiguration scenario. We developed the tool X-Reconfig supporting the paper contribution that we apply on the FESTO production system available in our laboratory at the Martin Luther University.

In view of the environment uncertainty of mobile robot navigating under the unknown and dynamic environments, the paper adopts hierarchical path planning ways which is two layers of global and the local optimization have been combined to implement autonomous mobile robot navigating. The genetic algorithm and the fuzzy theory were applied in the two layers separately, the genetic annealing algorithm is used to global path planning, and the hierarchical fuzzy coordinated strategy is used to local optimization procedure. It results in fewer rules, as well as much simplified and flexible design where new behaviors can be added easily. The simulation experiments indicate the effectiveness of the proposed methods.

In this paper, a wavelet network for the Electrocardiograph (ECG) data compression and the selection of its wavelet neuron are presented. The methods of the frequency-domain matching and the orthogonal least square (OLS) algorithm in selecting the wavelet basis and its quantity were discussed. We choose Morlet wavelet as the mother wavelet, and use the ECG signal for simulation. The result demonstrates that the number of Morlet wavelets whose spectrums locating at the ECG is up to 152. But after filtrated by the OLS algorithm, it reduces sharply. This method can make the size of the wavelet network driving to optimum and reduce the training time of the wavelet network significantly. The algorithm also can reconstruct the ECG signal very well. The results of simulation indicate that it can reflect the location and intensity of all waves correctly. Consequently, the algorithm has higher compression ratio and fidelity.

Optimizing the energy system is vital for supply safety and efficient operation. One part of such optimization efforts are demand side measures. This article discusses a simulation platform for automated demand side management, i.e. automated load management. Up to now, the strategies and algorithms that decided where and when to take influence on the loads were very primitive. The complexity of the system did not allow for intuitively designing smarter algorithms. As the energy system is a wide area distributed system, questions about system stability, SCADA (supervisory control and data acquisition), reaction times or the relation to the wider environment (customer processes, energy market, etc.) are very difficult to research. The presented prototype is intended to offer a research platform for evaluating potential algorithms for their real-world usage. All relevant parts of the overall process ldquointelligent gridrdquo are modeled into the world of discrete event simulation and first implementation results are discussed.

Automation and control systems provide their own programming and modeling paradigms in parallel to theory well known from computer science. Especially the concepts of component-based software engineering highly influence the design of embedded systems, which include automation and control systems. This work analyses what is and is not a ldquosoftware componentrdquo in the context of the two standards IEC 61131-3 and IEC 61499. Utilizing the definition of component frameworks and component system architectures, the potentials and problems of an integrative approach in order to utilize both standards within the same platform was discussed.
