In this paper we present a proof-of-concept implementation to demonstrate advantages of applying software-defined networking (SDN) to real-time Ethernet (RTE) networks. Potential advantages include the support of arbitrary network topologies, central and dynamic network (re-)configurations, the efficient use of bandwidth, and fast failover mechanisms at network level. To illustrate the advantages we implemented small proof-of-concept setups that demonstrate the features based on OpenFlow and openPowerlink. Finally, we built a practical showcase. Based on our results we believe the concept of a software-defined real-time Ethernet is worth pursuing as it may lay the groundwork for more advanced real-time networks.

There has been an increase of video surveillance systems in operation in public areas. The classical systems simply send the images to monitors. Nevertheless, there is a demand on giving more intelligence on these systems and asking them to automatically track objects or recognise people. One of the basic low-level tasks that these systems have to face with is the accurate deduction of the cameras' poses. We present a method that deducts these poses in an interactive way when the automatic method fails or generates a large error. The user is asked for mapping some points between the images from these cameras when the alignment between them fails in a completely automatic way. Experimental validation has demonstrated that with really few interactions, the reduction of the pose error is considerable.

The shift towards massively distributed energy generation demands more decentralized flexibility to meet strict power quality constraints of the electric grid. A cyber-physical system such as a smart grid can provide increased flexibility by utilizing additional information and communication technologies to better monitor the medium and low voltage distribution networks and to actively control grid-connected resources, ranging from loads to distributed generation, to electric mobility but at the cost of increased complexity. Essential future functionalities such as dynamic management of line use, fault detection and fast service restoration are only possible with appropriate sensors and actuators in place. These missing sensors and actuators on the distribution level are being developed today. This paper presents a standards based, low cost, open source, ICT emulation platform setup to test necessary networking concepts of these smart grid component prototypes already in various stages of development. Preliminary development results of the first example applications chosen: Customer Energy Management System, Smart Breaker, and Smart Meter, are shown in this work in progress paper.

Time Synchronized Channel Hopping protocol (TSCH) belongs to the new low-power MAC protocols included in IEEE 802.15.4e with better properties as a multihop network in industrial applications. An open issue in the standard is how to build and maintain the communication schedule. In this paper we have implemented a minimal recommended configuration and tested it against one proposed centralized scheduling optimization mechanism in a real WSN application.

District heating grids are complex systems where energy production has to match the consumption load while key system parameters like temperatures and pressures through the grid have to be kept within limits. The choice of a control strategy for the grid depends on the selected key performance indicators. The scientific contribution of this paper is a methodology for controlling the supply water temperature setpoint of a heat power plant using heat consumption predictions. The proposed algorithm aims to provide more heat energy to the difficult consumers when they need it the most. The required input information are the short term weather forecast, the supply hot water temperature propagation delays of the district heating grid as a function of the grid load level and consumption profiles based on historical data or heat consumption models. The methodology is applied on a simplified case study of a 120MW district heating grid. The results showed that within a specific supply water temperature range the performance of the grid in terms of minimum pressure difference at the consumers over a year was significantly better using the proposed proactive algorithm compared to simple reactive and constant temperature control strategies.

Diagnostic facility is one of the most important critical resources in the hospital. Patient scheduling plays an important role in managing these facilities, especially when they are shared between regular and emergency patients. Due to the non-stationary emergency arrival and waiting time targets of emergency patients, it is challenging for hospital managers to make appointment scheduling decision and real time scheduling decisions, i.e., how many regular patients could reserve the service and how to coordinate the service of both types of patients. To deal with this problem, this paper proposes a stochastic integer programming model by considering the uncertainty of emergency patients and their waiting time requirement. The objective is to minimize the weighted idle time, overtime, and patients' waiting time. Monte Carlo optimization is used to solve this model. Numerical experiments are proposed to show the usefulness of the proposed model for investigation of the influence of different parameters.

In this paper a flexible robot system for assembly operations in a semi structured environment is proposed. The system uses a moveable robot equipped with an arbitrarily mounted 3D camera and a 2D camera on the robot gripper for accurate object detection. The system is developed based on the Robot Operating System (ROS) and uses the state of the art trajectory planner MoveIt for collision free robot motion planning. The object recognition for the system is performed using a combination of the two camera's and robot end effector and the deviation of objects in the robot workspace is found to be in the range of 2.2 mm along X and Y axes. Furthermore, an implementation procedure of the proposed system for assembly task is explained.

Industrie 4.0 as one of the leading research and development initiatives for factory automation systems envisions a hierarchy of Industrie 4.0 components that exhibit a generic structure and behavior related to its utilization within production system life cycles. Each component is equipped with an administration shell containing a virtual representation of its characteristics. However, it is still unclear what kind of information the administration shell must contain. The granularity and the explicit information type must be determined. This paper provides an answer to this question by establishing a theoretical framework classifying Industrie 4.0 components. Criteria will be identified that make it possible to assign any Industrie 4.0 component to a specific production system hierarchy level and serve as meaningful administration shell descriptors.

Augmented Reality (AR) applications gain more and more relevance in various industrial applications, e. g. for product presentations, education, engineering, etc. In the industrial domain, especially in process supervision applications, a number of standards and guidelines have been established to ensure that the design of user interfaces meets the safety requirements of plants or factories. Hence, we seek an evaluation if these guidelines can be applied to AR applications. In this paper, we present the first preliminary results of a case study on the application of those standards to a visual AR application for in-field inspection and servicing scenarios.

A novel autotuning procedure is presented through application to an industrial in-line pH control system. The procedure has three advantages over classical relay auto-tuners: experiment duration is very short (no need for limit-cycle convergence); all data is used for identification (instead of only peaks and switch instances); a parameter uncertainty model is identified and utilized for robust controller synthesis.
