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.

In this paper a method is presented that allows an operator to hand-guide a robot along a predefined geometric path. This is a common use case in robot assisted surgery, which often has high demands on precision. In order to ensure the path accuracy of the robot, joint velocity and joint acceleration constraints are enforced to prevent undesired saturation effects of the actuators. Furthermore, necessary optimization steps are calculated in an offline phase and utilized during runtime to ensure realtime capabilities. The functionality of the method is evaluated using simulated sensor readings, controlling a kinematic model of the robot. While the focus is on surgical applications, the method can be useful in other domains as well, e.g. rehabilitation robotics or industrial applications.

This work is concerned with the implementation of an Adaptive Fault Diagnoser (AFD) for a system modeled by Timed Continuous Petri Nets under infinite server semantics, where the set of potential faults is a priori known, however their presence during system evolution, type, location, occurrence time, magnitude and behavior over time are unknown. There exist previous works reported in literature, where this problem has been solved, unfortunately the number of diagnosers used to detect, isolate and identify the fault is too large. Now, this work proposes a single diagnoser model where its structure is known and some of its parameters are updated depending on the fault occurrence. Considering this model, identification algorithms, based on heuristic optimization methods, are used to identify these unknown fault parameters. The analysis of the diagnoser parameters allows the faults detection, isolation and identification. The effectiveness of the proposed diagnoser is shown through two examples with different fault behaviors.

New production paradigms have been proposed along the industrial evolution in the attempt to solve problems like product customization, industrial manufacture of low quantities, and high variety of products in the same production plant (or even production line). Diverse architectures and devices have been used in order to achieve an optimum solution. Notably, the Evolvable Production Systems (EPS) proven to be an interesting alternative to deal with issues of mass customization. These systems make use of mechatronic and software agents to construct manufacturing plants, where the former may be associated to the systems' muscles (actuators and other mechanical devices), while the later are the systems' intelligence (software). Although such systems are becoming popular among many research groups all over the world, the construction of simulation plants capable of implementing the main EPS properties are not that easy. This paper describes a purpose of a Didactic Evolvable Production System, based on an open architecture, constructed purpose at the Federal University of Amazonas in Manaus - Brazil.

Equipment usually consists of many components arranged in hierarchical structure. In order to achieve efficient maintenance strategy, the system hierarchy should be taken into account. In this paper, we first give a nomenclature to describe a system composed of multiple non-identical components in a hierarchical structure, the system for an age-based and an opportunistic preventive maintenance strategies is modeled by using a Markov Decision Process (MDP). Then, near-optimal policies are found through the SARSA(λ) algorithm from Reinforcement Learning (RL), where the expected discounted cost is minimized. Simulation experiments to compare near-optimal policies obtained by SARSA(λ) are performed for both strategies with corrective maintenance and with age-based preventive maintenance policy obtained from renewal reward theory. We show that the proposed opportunistic preventive maintenance outperforms other strategies.

The control of low power systems, which include renewable energy sources, a local network, an electrochemical storage subsystem and a grid connection, is inherently hierarchical. The lower level consists on the control systems of wind sources (power limitation at rated value in full load regime and energy optimization in partial load regime) and photovoltaic (energy conversion optimization). The control problem at the higher level is treated in this paper and aims at generating the control solution for the energetic transfer between the system components, given that the powers of the renewable energy sources and the power in the local network are random variables. For the higher level, the paper proposes a mixed performance criterion, which includes an energy sub-criterion concerning the costs of electricity supplied to local consumers, and a sub-criterion related to the lifetime of the battery. It was defined an algorithm to control the energy transfer in the system, implemented by using fuzzy techniques and a deficit/surplus prediction of energy in the system.

Eboracum is an extensible modeling simulation framework for evaluation of reactive and adaptable wireless sensor networks (WSN), which provides high-level primitives for modeling platform and application aspects of WSNs. Combining application to environment-generated workload and computing/communication infrastructure, this framework allows to evaluate the efficiency of WSN configurations with regards to metrics that are meaningful to specific application domains and respective end-users. In this work, we demonstrate that Eboracum can be easily extended to support different types of nodes, events, as well as dynamic adaptability strategies. Moreover, this work discusses how to employ Eboracum to evaluate load balancing strategies and describe two different realistic scenarios, extending its primitives, for instance, to support mobile nodes and trigger events.

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.
