The objective of this paper is to describe an ongoing work that we are carrying out in the frame of an educational innovation project supported by the Education Advisory Service of the Vicerectorship for Teaching Quality and Innovation (University of the Basque Country, Spain). The project is driven by means of the subject of Industrial Informatics of the degree of Industrial Electronic Engineering and automatics (University College of Engineering of Vitoria, Basque Country University, Spain). The design of the project is based on the development of a collaborative work distributed among all the students of the subject, grouped in several teams or working groups. The work developed by each of those groups is complementary, and when all these parts of work are finished, all of them will fit together. The conclusion reached until this moment through the continuous tracking of the students is that there is an increased and more active attendance. Besides, the results reached by the students in different evaluations have improved those reached by means of the traditional paradigm of learning.

The distributed computer systems applied in industry are usually of the real-time type. In those systems the maximal system response time has to be always well known in order to ensure the functional as well as the safety parameters of the system. However, the system response time may be subject to change as a result of system development during its life cycle. As the given system grows, the response time lengthens. So it happens that in order to satisfy the real-time constraints, the response time T RES has to be reduced after the system development. One of the factors that have an influence on the T RES time, is the automata cycle of the communication system nodes. The shorter the automata cycle is, the more frequent is the data exchange between the CPU module and the communication module of the given system node, which improves the T RES value. However, having the node's application well implemented, shortening of the automata cycle may seldom be done by the application optimization. Then, the only solution would be to temporary shorten the automata cycle by execution of some of the most crucial parts of the user application. In this paper, a method for shortening the automata cycle is described.

The nonlinear nature of bioprocesses often leads to the occurrence of the self-sustained oscillations of the biomass concentration in continuous flow bioreactors. For some practical reasons, sometimes it is necessary to control the oscillatory behaviour, which is usually achieved by changing the dilution rate, but this is not always the best option. Hence, the main idea of this paper is to introduce an additional substrate, which has been previously diluted. Based on the numerical analysis of an unstructured mathematical model, it is shown that by mixing two various substrates (the main and the diluted one), it is possible to induce or eliminate the sustained oscillations. As a result, the contribution of both substrates to the mixture and the degree of dilution of the additional substrate can be treated as new control variables.

The paper proposes a new paradigm for the enterprise of the future, with respect to the requirements and the constraints it will be forced to face in order to progress and evolve. It is a paradigm which will take into account not only the complex relations between enterprise components - human, material and informational, but also the integration enterprise-society will all its aspects. There are presented some of the main trends in the control and management of manufacturing systems, in order to enlighten the evolution of the concepts towards that of Cyber-Physical Systems, which is the core of the proposed paradigm. A generic model of the next generation of Manufacturing Systems will be introduced, based on the paradigm of Intelligent Cyber-Enterprise.

This paper proposes a combined power quality-optimal control of the three-phase grid connected power converter. By using the technique of decoupling control, the mathematical model of the three-phase power converter is developed in the dq rotating reference frame and it is linearized around the operating point. The optimal control problem is with free-end point, infinite time horizon, and without constraints. The proposed optimal control is obtained as a solution of the Algebraic Riccati Equation. The numerical simulations based on the Matlab/Simulink software show the validity of the proposed solution.

Developing algorithms for Ambient Intelligence (AmI) environments involves testing algorithms using both simulated environments and user data. This has been traditionally done with simulators. While there are several datasets for Ambient Intelligence most of them have do not have an open format and a way to use them easily afterwards. We implement a software framework on top of an existing hardware platform for writing AmI applications that can also export a data dump consisting of heterogeneous sensor data matching several criteria from an AmI lab. Researchers using this framework can easily write AmI applications on top of shared datasets and easily test several algorithms against each other using real-world-data, a previously impossible endeavour.

This study presents a broad selection of methods and techniques for data transfers, starting with the TCP/IP protocol, its main enhancements, new non TCP protocols, and the class of applications and libraries able to sustain massive bulk transfers in HBDP networks. Distinctive features and comparison based on performance, effectiveness, efficiency and fairness are emphasized in each case. As a result, a new research direction has been identified, regarding generalization of the pipeline inter-process communication mechanism at networking level, by making fast interconnections between pairs of data producer/consumer processes distributed over the Internet.
