This paper presents the design of an active flow control (AFC) system for commercial aircraft based on a dense wired/wireless sensor and actuator network. The goal is to track gradients of pressure across the surface of the fuselage of commercial aircraft. This collected information will be used to activate a set of actuators that will attempt to reduce the skin drag effect produced by the separation between laminar and turbulent flows. This will be translated into increased lift-off forces, higher speeds, longer ranges and reduced fuel consumption. The paper describes the architecture of the system in the context of the European research project DEWI (dependable embedded wireless infrastructure) using the concept of the DEWI Bubble. A simulator architecture is also proposed to model each process of the AFC system and the DEWI Bubble. To the best of our knowledge this is the first approach towards the use of wireless sensor technologies in the field of active flow control.

Industrial control system is a general term that addresses several types of control systems, including supervisory control and data acquisition systems, distributed control systems, Programmable Logic Controllers and etc. There is no doubt that protecting PLCs from cyber-attacks is very important as they directly control industrial processes. In critical infrastructure, any successful attack on PLC could be as serious problem particularly in DCS. In this paper we approach an authentication solution based on cryptography to avoid unauthorized accesses in ICS.

Commercial-of-the-shelf based multi-core systems present timing anomalies that cannot be ignored by the real-time systems community due to their unpredictable behaviour. These timing anomalies, often caused by applications' uncontrolled accesses to shared resources such as the components in the memory hierarchy or in the I/O subsystem, introduce interference that may lead to deadline misses if the problem is neglected. The Acquisition Execution Restitution (AER) execution model was previously proposed to circumvent this problem and, therefore, mitigate inter-task interference. In this model, applications decouple communication (acquisition and restitution phases) from the actual execution in a way that at most one acquisition or restitution phase is in execution at any instant of time while the execution phase of different tasks can progress in parallel on multiple cores. Thus, keeping each task's derived worst-case execution time closer to the one measured in isolation. In this paper, we study the AER execution model and compare it against a global Earliest Deadline First (EDF) approach where interferences are considered. Our results show that a priority assignment heuristic which assigns the priorities based on the tasks' periods dominates all the other proposed heuristics and that due to interference it can also schedule task sets which are not schedulable by using the global EDF approach.

Industrial control systems rely more and more on digital technologies. Although the cyber risk such technologies induce is widely judged as serious, especially for critical infrastructures, these systems have generally not been designed to serve cybersecurity purposes. Instead they were thought first for serving operational efficiency. It thus becomes critical to study cyber threats in industrial environments and experimental test beds are needed to evaluate risks, physical consequences of cyber incidents, and performance of countermeasures. The test bed we present here focuses on studying cyber risks and their mitigation in IEC 61850 power utility automation systems. The operational part is composed of engineering computers, supervision software, off-the-shelf intelligent relays (Intelligent Electronic Device - IED), a hardware-in-the-loop process simulation, and the cybersecurity tools include an attack generation station and a network analyzer. In this paper, we present the operational part, giving details on the power grid hardware-in-the-loop simulation and its importance in the understanding of cyber consequences on the global system. The article concludes giving preliminary experimental results showing consequences of a false data injection attack on a simple electrical architecture.

A practical method for the design of an in-vehicle wireless sensor network operating in a truck is presented. The network has been dimensioned using promising candidate sensor applications that were chosen based on a set of key criteria including safety, security, and timing-criticality and commercial viability. An extensive set of experiments were carried out to determine characteristics, feasibility and ease of integration of such a network into the vehicle electrical system. A network of 10 node positions and 3 possible gateway positions was used as a reference platform. Initial results indicate that for truck variants with up to 5 axles, there is near universal coverage using 2.4 GHz IEEE 802.15.4 radios with link budgets above 100 dB. Links between sensors and all gateway positions have been found to support above 90% packet reception rates at received signal strengths of about -70 dBm, with gateway positions in the central and rear chassis areas performing best. Current estimates are that such a network is robust enough to support sensors of low safety, security and timing criticality.

Within the multi-disciplinary engineering process of a cyber-physical production system, the information about the plant is increasing steadily. Different departments work on separate domain-specific models and tools allowing a specialized view of the same system. However, data exchange and linking the heterogeneous information across domains is a critical issue. This paper investigates behavior modeling of automation components out of interdependencies coming from different disciplines such as mechanics, electrics, and software engineering. By this, the interlinking of the domain-specific models, as an enabling step towards early cross-domain validation and facilitated system evolution, allows a common understanding of the correct functionality of the system. The concept will be explained through the example of a pneumatic stopper and evaluated in AutomationML, an emerging standard in automation, to store and exchange artifacts between domain-specific engineering tools.

A major aspect of Cyber-physical production systems is to increase adaptability regarding the physical structure of manufacturing components as well as of the applied software systems. This is motivated by the increasing engineering efforts of manufacturing systems due to changing requirements, varying product variants and also malfunctions. In context of the method plug and produce physical adaptability, the customization of the plant layout of a production system, is an integral part. Physical adaptions become necessary when e.g. the production process is changed, the process performance requires to be optimized or manufacturing components need to be replaced. Consequently, a technique for determining appropriate manufacturing modules for a given production process is needed. In contrast to current methods this paper presents a novel approach for physical adaptability especially respecting the discrete system behavior of manufacturing modules. For this purpose, subgraph isomorphism is combined with a semantic matching filter together with additional matching criteria. Both, matching filter and matching criteria are tailored to the use case of plug and produce. Based on a case-study the proposed method is evaluated. The matching quality is assessed using macro-averaged precision and the normalized discounted cumulative gain.

This work presents the concept and methodology as well as the architecture and physical implementation of an integrated node for smart-city applications. The presented integrated node lies on active RFID technology whereas the use case illustrated, with results from a small-scale verification of the presented node, refers to common-type waste-bins. The sensing units deployed for the use case are ultrasonic sensors that provide ranging information which is translated to fill-level estimations; however the use of a versatile active RFID tag within the node is able to afford multiple sensors for a variety of smart-city applications. The most important benefits of the presented node are power minimization, utilization of low-cost components and accurate fill-level estimation with a tiny data-load fingerprint, regarding the specific use case on waste-bins, whereas the node has to be deployed on public means of transportation or similar standard route vehicles within an urban or suburban context.

The increasing complexity of software in production systems leads to a growing relevance of testing. This trend will continue due to the flexibilization, and IT networking of production systems. This paper proposes a discussion about the requirements of future production systems which will be reconfigurable, decentralized controlled and will consist of autonomous components. From these predicted requirements, new challenges for functional testing are derived. To elucidate these challenges, three use cases illustrate when testing measures will be necessary within the operation phase of production systems.
