The paper deals with the description of the possibilities how chaos can be used for cognitive tests using virtual reality technologies. In the first part is description of relation between virtual reality, cognitive testing and chaos. N ext chapter deals about chaos and possibilities of its usage. In the final are mentioned three ways of possible chaos use in cognitive testing and also proposal of chaos implementation into environment of virtual CAVE is here. This is main idea for better result obtaining for cognitive testing in this case.

There are many active intermediary devices in computer networks. The network has to be verified whether it functions as it should - i.e. whether some intermediary device in not misconfigured. It is a difficult task, because various scenarios must be tested, which takes time. Fortunately, there are tools that help to automate this process. However, the existing tools are mostly oriented towards generation of specific periodic traffic for network performance analysis, and it is difficult to use them for functional verification of the network. Therefore, we propose in this paper a new method, along with the corresponding tool, which is targeted towards generation of certain traffic and analysis of the network response to verify its function. The primary focus of the method is for testing of local area networks, which usually consists of switch devices. The experimental results proved that the proposed tool is usable to verify specific functional aspects of the switched networks. The tool can be used in education to verify students-configured local networks or to test software switches implemented by students.

In this paper, a digital calibration method for analog integrated circuits in nanotechnologies is proposed. Calibration was applied to a variable-gain amplifier (VGA), and it was aimed at the input offset voltage. The first part of the paper brings motivation for our research. Consequently, fundamentals of the proposed method and its implementation in 130 nm CMOS technology node are explained. The whole system operates with the supply voltage of 0.6 V. Then, verification results obtained mainly by simulations and partly obtained by the measurement of prototype chips. In all simulations, Monte Carlo analysis was used in the temperature range from −20°C to 60°C. With the use of calibration, the input offset voltage distribution mean value ranges between $299mu V$to $413mu V$, and standard deviation ranges between $356mu V$ - to $802mu V$. The measurement results of the VGA without calibration shows, that input offset voltage distribution over 60 samples reaches mean value of $403mu V$ and standard deviation of 3.45 mV.

Proposed paper deals with the turn-taking mechanisms in the dyadic human-human interactions in Slovak language. Described research aims to bring an initial analysis of the turn-taking behavior. We decided mainly to focus on overlapping speech segments. Human-human dyadic interactions were analyzed on the small corpus of interactions, to identify intention of taking a floor by the listener before speaker's turn end.

In Internet of Things network connects a big amount of different devices. These devices can gather or send data and they are used in many areas e.g. Education, Environment, Health security and others. In order to build an effective network with a great communication ability it is necessary to know what communication in Internet of Things offers. With communication capability knowledge we can build effective Internet of Thing networks. In this paper, we examine different protocols, technologies, routings, quality of communication and some negative impacts on communication. We research these things to better understand, where the potential for improvement is.

This paper presents an embedded height above ground level (AGL) control of quadcopter employing popular Arduino microcontroller. The goal was to enable pilot to turn on the automatic AGL by a switch on the remote control, but to be able to take over the throttle control without a need of switching it off.

A group of fuzzy rules is a human-interpretable knowledge representation which is used in various fields of study such as control and knowledge discovery in databases, e.g. for inferring on output based on input variables. It makes use of the notions of fuzzy logic such as fuzzy sets, membership functions and membership degrees. Truth values represented by membership degrees may be any real number between 0 and 1. Effective definition of membership degrees through membership functions for particular applications requires a tool able to set membership functions and to generate inputs for various knowledge discovery algorithms. Similarly, various algorithms for making fuzzy rules and validating are required as well. In addition, modifications have to be possible as research in this scientific area is active. Since many fuzzy rule related algorithms and their modifications are not available for development of programs, software library Fuzzy Rule Miner is presented in this paper. This software library is written in Java and it can be used for helping students with fuzzy logic related calculations, fuzzy rule discovery and the use of fuzzy rules. It can also serve as a support library for complex software programs working with fuzzy rules.

This paper presents possible ways to solve the questions: How to drag the young people and kids in to the World of Science and Technology? What is the right time to start working with children to motivate them towards these fields? The answers are verified by more than ten years of author's experiences in developing of education e-learning projects, organization of popularization and education activities such as “Days of experiments”, courses and competitions about robots and electronics. The attention is focused on courses called “Build a Robot”, “Electronics as a game”, and “Building and programming robots” for the target groups of elementary and primary school pupils. The experiences confirmed that the optimal age for pupils of elementary schools to start a systematic co-work is between 8 and 9 years (3rd and 4th grades elementary school).
