Design systems used in the field of electrical apparatuses
Stejskal, Jiří ; Krejčí, Jan (referee) ; Valenta, Jiří (advisor)
Bachelor´s thesis is engaged on the base of submitter´s requests company OEZ, s.r.o. and is divided into two parts. The first part of work deals with the most often used 2D CAD systems that are used by designers according to their answers in the area of suggestion of electric switchboards low voltage. In the work are described main possibilities of these systems, then what kinds of data format are supported by them. In the second part of the work are described programs established on calculation of warming switchboards. It goes about programs, which supply concrete producer of switchboard case, and further programs based on method of final elements and method of final volume, which enable graphic representation of results.

Creating an Accounting Procedure for Fixed Assets
Stejskal, Jakub ; Svirák, Pavel (referee) ; Pěta, Jan (advisor)
The bachelor thesis is focused on internal guidelines of the company BZCompany international s. r. o. The first part is focused on internal guidelines, accounting, accounting and tax depreciation and legislative aspect of the matter. The second part is introduce BZCompany international s. r. o. and examines the optimal solution for internal guidelines with regard to problematice with long-term tangible assets. In the last part of the bachelor thesis indicate optimal design for internal guidelines.

Possibilities of usage of computational systems for switchgear assembly design
Stejskal, Lukáš ; Ing. Jan Krejčí (ext.) (referee) ; Valenta, Jiří (advisor)
The main goal of my bachelor's thesis is to descriebe the CAD systems that are used by engineers to design the electric switchboard and the electric network. In my thesis I descriebed the main options of these systems. The other thing is which data formats are supported for data export and import. In the second part of my thesis I'm dealing with designing the electric switchboard and his type-testing. I'm only interested in the thermal and short circuit endurance during the designing part and during the switchboards testing part as well.

Reaction synthesis of bulk intermetallic materials from kinetic spraying deposits
Stejskal, Pavel ; Roupcová, Pavla (referee) ; Jan, Vít (advisor)
This work deals with issues of preparation of intermetallics based on iron, nickel and titanium aluminides. It works with an idea of preparation of bulk material by reaction synthe-sis from kinetic spraying deposits by cold spray. Theoretical part is concerned with phases and compounds of these aluminides for structural applications, their characteristics and present fabrication. In experimental part there are studied microstructures created by annealing of deposits.

Measuring of Velocity Profiles in Liquids by Using of UVP
Kárník, Jan ; Stejskal, Jiří (referee) ; Štigler, Jaroslav (advisor)
The following bachelor's thesis deals with one possible way of determination velocity profiles in liquids. Content of the thesis is focused mainly on the method of the UVP (Ultrasound Velocity Profile), on the ways and principles of measuring, on its pluses and cons and it´s comparison with the other conventional methods, like for the example the PIV (Particle Image Velocimetry) and LDA (Laser Doppler Anemometry). There is also the possible placement of the transducers to the measuring system discussed. Furthermore the thesis deals with trouble in the test measurement. At the beginning this work deals with familiarization with principle and function of the measuring device and with the device for the method UVP itself. Apart from the UVP measuring method the thesis also deals with short description of the competitive methods – PIV, LDA, which are used to measure the velocity profiles nowadays. Particular attention is given to the PIV method, which significance is currently growing. In conclusion, there is comparison of different methods with the UVP method made and there are the future steps to realize the successful measurement with UVP method also discussed.

Breathing simulator
Stejskal, David ; Jedelský, Jan (referee) ; Lízal, František (advisor)
The purpose of this thesis was to create realistic breathing cycles for breathing simulator and than to verify the functionality of the simulator. The first section of this thesis was conceived as an general introduction to problematics of breathing. This section describes the construction of the lungs, the breathing mechanism and lung volumes. The subject of this study were also important factors that affect human respiration. Processing of acquired data and creation of breathing cycles for breathing simulator is described in the second section of this thesis. Five specific breathing patterns were created. The experimental verification of the breathing simulator functionality is part of the second section.

Hough Transform and its Variants
Stejskal, Jan ; Přinosil, Jiří (referee) ; Říha, Kamil (advisor)
This thesis focuses on basic principles of Hough transform for the detection of lines, circles and arbitrary shapes, their algorithms, computational complexity and preparation of a picture for detection. The description of implementation of individual algorithms and creation of an aplication that demonstrates their properties. Implementation has been done in programming language MS Visual C++ with the help of open source library OpenCV and user interface has been created using IDE Qt Creator 4.13.2 (Community).

Test of Vibration Power Generator with Longitudinal Coil
Stejskal, Jan ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with activation and testing of Vibration Power Generator with Longitudinal Coil which was designed at Brno University of Technology. One of goals of the thesis is to compile simulating model of this device and to compare its results with data gained from measuring device used while testing on the vibration stand. This Vibration Power Generator could be theoretically used in aerospace industry as well as in other branches of industry. It´s important to minimalize its dimensions and weight as much as possible. On the other hand, there are some parameters which should stay unchanged with respect to troublefree work of the device. According to those facts, some changes of construction were proposed within this thesis.
