The speed of information technology development is ever increasing. The appropriate information can be easily provided for and often it can be visually presented. The access to relative information, documents, etc., takes advantage of Hyperlinks, often supported by the Internet of things. The paper deals with a technology that makes data interpretation much easier for the users. It is of no consequence for them, where and in what form the information is stored. The user's access to information does not imply knowledge of a specific program, X, or knowledge that his piece of information is in file, Y. All such knowledge is Hyperlink comprised by unified GUI (Graphic User Interface) with the final goal of VRE (Virtual Reality Environment) interpretation. The Internet of Things implies new possibilities to designing and implementing of distributed and hierarchical information systems.

The paper is devoted to 3-axis positioning of a CNC machine model. This desktop CNC machine is used here as a tool for circuit board holes drilling, designed using the EAGLE software. Connection between the EAGLE software and the CNC machine model is provided by monitoring and visualization application, created in the visualization system Control Web 6. This application receives exported data from the EAGLE software via a DDE communication protocol and using suitable algorithms transfers these data to desirable drilling points coordinates. These coordinates are then sent to a PLC controller which controls the CNC machine via the OPC communication protocol.

The paper deals with the issue of the drift of residual methane release from the extracted seams of the underground coal mines. Methane is a hazardous gas, which, thanks to its density, tends to gather under the ceilings of mine shafts or rooms where it is present. When mixed with air, it is explosive within the 5 - 15 % range and that is the reason for the highly hazardous nature of the given gas despite the fact that under normal conditions, it is not dangerous for people. The objective of the present paper is to examine, using numerical gas glow modelling a potential building protection design for buildings located in areas with terminated mining activity and thus exposed to the risk of methane ingress and, as the case may be, causing in estimable losses of property or even human lives. The exclusiveness of our approach involves the effort at visualising and showing how the gas will behave in a porous environment in the model situations we put to the test. Unless numerical flow technology, generally referred to as CFD (Computational Fluid Dynamics) software, is used, the situation in the underground may practically never be identified and it is specifically thanks to the use of the Fluent software that we can theoretically model and subsequently realise how the surrounding conditions may change and affect flow from the underground to the surface and change the immediate conditions there. The Gambit software tool was used when creating the geometrical model of the working area; the CFD Fluent software by ANSYS, Inc. was used to model gas flow.

For fitting the measured data, a new approach is suggested, which is based on using the Mittag-Leffler function and which means that the data are fitted by a solution of an initial-value problem for a two-term fractional differential equation.

At the Technical university of Košice was developed and designed equipment for static tests of pipe conveyer belts. The article deals with using of new Computer Integrated System for the automatized measuring of strength in the conveyer belt of pipe conveyor. Measuring system, measuring process and form of record results and their interpretation are presented in this paper. Values from 24 pieces of strain gauges are recorded simultaneously. The valuation of measurements was performed by statistical characteristics, Shapiro-Wilk normality test, test for the Weibull distribution and test of casualness. We also created mathematical description from measured variations of compressive forces by using non-linear dependence.

In general, heat transfer is expressed by heat flux which depends on thermal resistance and temperature difference. Thermal resistance is determined by heat transfer area and coefficient of heat transfer. In case of convection heat transfer are considered heat transfer more often between liquids or liquid and grain material what is specific for area of raw materials processing. The values of convection heat transfer coefficient are normally gained from the experimental measurement. The contribution deal with software support for calculation of convection heat transfer coefficient, dimensionless criteria and elementary thermo-physical properties of gas media from area processing of raw materials with known composition and temperature. Functions were created in MATLAB. In article coefficient of convection heat transfer for every type of convection are expressed by dimensionless criteria where elementary thermophysical properties are proposed. According to the expressed relations was proposed general form of relation for coefficient of convection heat transfer calculation. Dependencies of convection heat transfer coefficient on different factors are showed.

Mining production in underground spaces will be in the near future realized by autonomous systems without human presence. As the production is connected to natural raw materials deposits, where the process environment models and activities cannot be fully determined, the human supervision will be still necessary. Classical process control, with the external system description of the dynamic behavior, uses the transformation of input actions to output reactions for the model design. Similarly for the process visualization the classical methods - SCADA (Supervisory Control and Data Acquisition) systems are used. Modern control theory is based on state representation of systems, caused by the necessity to obtain more information to understand and describe the dynamics of complex system in the control process. Resulting state space model represents the dynamic properties of the system. The behavior of system in the state space is then represented by the state trajectory - given by the values of state variables in the observed time period. The problem is that the state variables, in many cases, do not have the physical dimension and do not describe surrounding environment. The Virtual Reality tools provide the possibility for visualization of such a virtual and complex systems description in special artificial space.
