Means augmented reality - research study
Trentin, Tomáš ; Andrš, Ondřej (referee) ; Kovář, Jiří (advisor)
The goal of this bachelor thesis is to create a summary of accesible information about the most widespread means of virtual and augmented reality. First section defines the difference between the virtual and augmented reality, the two subsequent chapters describe particular headsets and smartglasses, and the goal of the last section is familiarization of the software means for creating VR/AR applications and games.

Virtual prototyping for machine tools
Klement, Roman ; Kovář, Jiří (referee) ; Hermanský, Dominik (advisor)
This bachelor thesis explores the possibilities of creating a virtual prototype, which is to be understood as an advantageous approach of designing new machine tools. Different approaches regarding the afromrentioned proces are described in the research part. Following the research, a simple virtual prototype for kinematics optimisation was made.

Temperature measurement of a machine tool
Sloboda, Tomáš ; Kovář, Jiří (referee) ; Hermanský, Dominik (advisor)
The aim of this thesis is to get acquainted with the theory of temperature measurement, various kinds of contact and non-contact gauges, their construction and accuracy. It also tries to explain the basic knowledge of machine tools and their thermal load. Part of the work is to test this knowledge with experiments in the company Intemac Solutions s.r.o. and Faculty of Mechanical Engineering at Brno University of Technology. The obtained results are further evaluated and compared with the help of graphs and tables. To process the obtained data from the sensors, program Labview was used and FLIR Tools was used for thermal pictures taken with thermal camera. During evaluation, it was also necessary to consider measurement errors caused by the factors resulting from the physical laws described in this work.

Optimization of the DC motor state space controller for FPGA
Maliszewski, Michal ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
This thesis deals with the optimization of state space controller of DC motor on FPGA in LabVIEW environment on NI cRIO platform. In the first part, the state space model of the given DC motor is presented in Matlab/Simulink and then the position feedback controller with steady-state error elimination and with state observer with error compen-sation using LQR method is designed. The thesis continues with transforming the con-troller to LabVIEW environment where the code is edited for FPGA use. Next, the fo-cus on FPGA hardware resources consumption optimization leads to careful work with fixed-point data type. After successful code compilation on target hardware, the real given DC motor is connected and the series of tests are performed. The output of the thesis is working state space controller running on FPGA and the graphical user inter-face on real-time host cRIO, which enables the user to control the plant and save the data on the disk.

Character of Luboš Fišer's Work and Style of Composing, Taking into Account the Nature of Solo Piano Pieces
Kovár, Jiří ; Gregor, Vít (advisor) ; Tichá, Libuše (referee)
Title : The character of Lubos Fiser's work and his style of composing, taking into account the nature of solo piano pieces. Abstract : This paper "The character of Lubos Fiser's work and his style of composing, taking into account the nature of solo piano pieces", is focused on all of his pieces. The first part of Fiser's work falls within the artificial character and the second part focuses on the film, hence the incidental music. The main purpose of this thesis is to update and clarify Fiser's review of his complete achievements and composition style into the typological classification and the individual development throughout various creative stages. Consideration will be also given to the creation of solo piano pieces that illustrate and highlight specific features of Fiser's creative development. Characteristics of these pieces will be linked to their structure in the form and tectonics, with regard to the styling tools and related interpretive issues.

Magnetické pole v jádru Galaxie
Hamerský, Jaroslav ; Karas, Vladimír (advisor) ; Kovář, Jiří (referee)
In the present work we study the properties of accretion tori orbiting black hole. Our approach to this problem comes from the solving of general relativistic magnetohydrodynamic equations, which follow from conservation of the energy-momentum tensor, the particle number and from Maxwell's equations. We solve these equations by numerical methods which are described in Chapter 1. The formalism of tori which we consider here is described in Chapter 2. We are interested in tori with constant density of angular momentum and Fishbone-Moncrief tori mainly. We study accretion rates in these tori when the mass of black hole is increased suddenly and so the equilibrium in the torus is corrupted. For tori with constant density of angular momentum we study the influence of the presence of toroidal magnetic field on accretion rates.

Automatic control system for the cooling water circuit in the laboratory
KOVÁŘ, Jiří
The bachelor thesis focuses on problematics of feed-back working automatic detection systems. The main aim of the work is development of an automatic detection system, equipped with the water sensors, that should prevent damages caused by unwanted water leak. The system is equipped by sensors, control units, communication module and output switches that enable to activate the alarm, to send the information SMS, close the water pipe and to deactivate water-cooled devices to prevent their overheating. The written part of the bachelor work consists not only of the theoretical background of used components but also describes electrical circuits, schemas and functionality of the system.
