This work is deals with processing and analysis of ECG waves, namely with recognition of ECG samples with diagnosis of myocardial infarct and arrhythmia from samples. As a base concept for comparing the ECG wave to the typical wave,Template matching method is used, which can find the best similarity between the test sample and ECG templates. With respect to the metrics it calculates their relative similarity, too. Input data were obtained from the project PhysioNet, gathered at the Institute of Cardiology at the University Clinic Benjamin Franklin in Berlin and digitalized in the National Metrology Institute, Germany under the name PTB ECG database. The outputs are the similarity coefficients of the twelve conventional ECG leads and the six basic parameters of waves. The results of our proposal with used methods for data preprocessing and implemented algorithm are comparable with the results obtained by systems based on neural networks classification. It has the potential to help physicians in the initial analysis and identification of the patient's condition.

This paper introduces a new modeling method for improved engineering processes in product modeling. The proposed modeling is intended to be implemented in current product lifecycle management (PLM) systems. It is relied upon the information content based product modeling as proposed earlier by the authors. In this modeling, human intent based engineering objective and contextual connection definitions are applied at the generation of adaptive actions in order to control parameters of engineering objects at engineering decisions. In this paper, methodical elements of information content based product modeling are introduced and discussed. Activities connecting levels of the content structure and developing human intent into decision level-by-level are explained. Following this, human intent definition based definition of engineering objectives is explained as one of the main content processes. Next, spaces are defined where intent, behavior, and decision entities are paired with engineering object entities. As key elements of the proposed modeling, decision process and consequence analysis for a change defined by an adaptive action as a result of a decision are outlined. Finally, basic issues for implementation of the proposed product modeling are discussed.

This paper presents educational content of the vocational education and education at all as a broad information system. The authors point out the absence of formalization in educational content notation analysis and design on the contrary of other fields, where modeling plays irreplaceable role. For modeling this information system they use Unified Modeling Language UML, which is specialized language for system specification primarily in object-oriented manner. The paper further refers to a parallel between object-oriented analysis and design OOAN and object-oriented didactical transformation OODT. Modeling in OODT context leads to models with zero redundancy in educational content which represents so called basic curriculum. Identifying that basic curriculum is still unresolved and discussed because the pedagogical theory hasn't defined methodology for explicit expression of the basic curriculum yet.

A novel aspect of human-robot interaction (HRI) can be put on the basis, that the robot side is implemented on a state-machine (fuzzy automaton), which reacts the human intervention as a function of the robot state and the human action. This platform is suitable for implementing quite complicated action-reaction sequences, like the interaction of human and an animal, e.g. a behaviour of an animal companion to the human. According to this paradigm the robot can follow the existing biological examples and form inter-species interaction. The 20,000 year old human-dog relationship is a good example for this paradigm of the HRI, as interaction of different species. In this paper, for ethologically inspired HRI model implementation, a fuzzy model structure built upon the framework of low computational demand fuzzy rule interpolation (FRI) methods and fuzzy automaton is suggested. For demonstrating the applicability of the proposed structure, some components of a human-dog interaction FRI model, which also suitable for HRI, will be briefly introduced in this paper.

This article is describing protocol implementation for real-time voice transfer from Windows based Operation system to embedded system based on Linux Open Source OS. There is presented implementation of A-law based algorithm as codec, which is usually used in digital telecommunication signals mostly in Europe. For real-time voice transfer we are used RTP protocol. Presented Solution works both direction but only in half duplex mode. Main applications can be security systems and robotics or mobile robotics solutions with interactive features.

Semantic Web has reached the point where basic research is supposed to be replaced (at least partially) by research aiming at practical aspects of using the Semantic Web. Ontologies, as the essential technology in this area, have been under the spot light which produced some results, e.g. the Semantic Web Search engines like Watson, Swoogle etc. These help in finding and locating semantic information on the Web. However, they do not support users to quickly understand what an ontology is about, what information it contains. We argue in this paper that vector description, as a snapshot of data comprised by ontologies, may help while understanding of particular ontology. In other words, instead of depicting a whole ontology all together, we prefer reduction of information given and therefore avoid users being overwhelmed and thus help with orienting in a wide offering of ontologies on the web.

Recent investigations in the field of complex networks include the analysis of distributions of connections in particular networks and the clustering properties of networks. In the first part of this presentation we analyse a network: the dependency network of the software packages of the Ubuntu distribution of GNU/Linux. It is a directed network, and we analyse the degree distribution of the network for in-degrees (connections directed into a node, the dependent packages), out-degrees (connections directed away from a node) and plain degrees. We also analyse the clustering properties of the network. In the second part, we discuss the teaching of these topics at the college level. Using the NetworkX modul for the Python programming language students can easily investigate these properties of the package dependency network.

The case study presents modern robust control methods of the Bergman minimal model of Type I diabetic patients under intensive care using computer algebra: the disturbance rejection LQ control or minimax control (as extension of the classical LQ control) and the robust H¿ control. It is shown the minimax control has limitations in practice, but employing reduced Gro¿bner basis on rational field, it is possible to approximate the theoretical solution and so getting a better solution than LQ does. The symbolic and numeric computations were carried out with Mathematica 5.2 and with its CSPS Application, as well as with MATLAB 6.5. In case of H¿ control, the graphical method in frequency domain- implemented under Mathematica by-is extended with a disturbance rejection constraint and the robustness of the resulted highorder linear controller is demonstrated by nonlinear closed loop simulation in state-space, in case of standard meal disturbances.
