In this work, we compare nine methods of experimental identification (polynomial models, artificial neural networks and deterministic methods). We use measured data from the small turbojet engine iSTC-21v to create experimental models through programming environment MATLAB/Simulink. Comparing the output of these calculated models with the real measured data, we get the amount of the mean absolute...
This paper presents an event-driven approach for handling variable rate sensor feedback. Such systems are challenging as most discrete-time modeling techniques are based on constant sampling rate. Existing methods include oversampling, which is rather resource-intensive and linearization or linearizing feedback, which requires calculations for each operating point of the system. As an alternative...
For a small gas turbine engine test cell newly developed and built at the University of Defence in Brno a system for automated measurement and engine test control was designed. The system is based on National Instruments Compact RIO hardware and LabVIEW software and is implementing supervisory control and data acquisition (SCADA) architecture. This paper describes the requirements that drove the decision...
The purpose of this invited plenary paper is to present authors' ideas of the actual state of the smart transport and trends of its potential further development, including a brief outline of visions going up to both short-time and long-time horizons. The aim is to create a framework for another wide domain where machine intelligence and informatics (the main topics of the SAMI 2016 conference) could...
We show in this paper our experiences and results in teaching different user interface technologies. Our focus is one of the biggest ERP solutions, which offers several UI possibilities. We have recognized that different technologies require different knowledge from programming, design, fantasy and robustness aspects as well. On the other hand the students' age, educational environment, graduate level...
This paper deals with stochastic weight update methods for neural networks learning. We will study two methods, stochastic weights selection and stochastic neurons selection. These methods have to allow better parallelization of the backpropagation algorithm, although in this paper we will use only the conventional serial implementation. We will use meteorological data for experimentation with neural...
The aim of this study is to improve a fuzzy rule based system that helps to manage heart failure patients in home telemonitoring. The system is intended to give notifications to a decision-making support system and medical experts when there is a possibility of death for a telemonitored patient. The improvement consists in inclusion of a formulated dissimilarity measure into the algorithm for creation...
In this paper we presented a simplified solution of an artificial neural network which matches the patterns of fingerprints. As universal approximator, the artificial neural networks (ANNs) are able to bridge the non linear outcome of the superposition of elementary failures. We built up a multilayer feedforward network, and used the back-propagation on a medium size sample, to reach better accuracy...
In this paper we provide modification of approaches for extraction of keyphrases from single textual document (without external information) based on the hierarchical concepts created upon the text of particular document. For the creation of hierarchical concepts method from area of Formal Concept Analysis (FCA) is used, which organizes objects into concept lattice (structure of hierarchically organized...
This paper presents a heuristic solution for the inverse kinematics problem. The heuristic consists on combining the distance between the actual position and the desired position of the gripper with the direction of the best manipulability of the robot. Theoretical results are validated by digital simulations resolute.
Vortex ring state, or settling with power condition, of tail rotor of helicopter Mi-17 is investigated by numerical methods of Computational Fluid Dynamics (CFD). Distinct shape of inflow-thrust curves is described and various flow patterns at different locations of the curve are identified. The shape of the curve is identified as a feature responsible for uncontrolled rotation of helicopter at the...
In the information technology more and more computing devices have several sensors which can provide lot of data we can use for specific purposes. The newest mobile phones or the Internet of Things (IoT) devices can have many kinds of sensors like temperature, barometric, light, magnetic, acceleration. The sensors of these popular devices are in lack of expensive calibration and provide useful but...
With the development of the Internet and the increasing amount of opinion-based data, an ordinary person is not able to process them all. Therefore the importance of automated processing of this data grows. Processing of text data is very difficult. The presented approach is designed to help with the classification of posts in which the author describes his opinion. We focused on the possibility of...
One of the main challenges at definition methodology, planning, and configuration of an engineering course is recent dramatic change of engineering methodology at leading industrial industries. Engineering systems are applied to integrate all engineering activities for entire lifecycle of industrial products. At the same time, engineering was tailored to multidisciplinary structure of recent product...
The MANETs (Mobile Ad Hoc Networks) are increasing on popularity due to their dynamic nature, minimal infrastructure requirements, deployment cost and their self-configuring attributes. Advances in low power computing and communications and increase of transfer rates makes MANETs even more desired in different real world applications. These properties make them ideal for employment in tactical military...
A complex algorithm development progress for mobile robot (MR) usually requires a priori simulation of the whole dynamic environment before it is applied on a real-world robot. In order to reduce the development time and avoid programming mistakes it is recommended to use the same language for both simulation and real-word testing. The paper presents a certain use case for the simulation-based approach...
Linked Data resources are identified by Uniform Resource Identifiers. It is an important step in any Linked Data project to define the conventions for URI assignments. In some cases resources already have their natural identifiers, or they can be inherited from previous databases. However, there are cases when frequent insertions of triple sets occur without any convenient way for identification and...
There are many optimization algorithms that can be used for the purpose of optimization. Those algorithms are searching the so called candidate space. Those candidates are possible solutions. We are trying to find the one that represents the best solution as possible. It is possible to use parallelization to speed up the search. We introduce in this paper an approach how to use parallelization, where...
