HMSIW linearly polarized slot antenna array
Horák, Lukáš ; Pítra, Kamil (referee) ; Hubka, Patrik (advisor)
In this work is proposed a HMSIW linearly polarized slot antenna arrays. The first antenna array is composed of four U-shape slots and the second antenna array is composed of four U-shape slots with three patches placed near the magnetic wall of HMSIW. The patches improve radiating parametrs of the proposed antenna array. The proposed antenna arrays are manufactured a measured.

Možnosti optimalizace kabelových svazků traktorů a způsoby jejich testování
Horák, Lukáš
The diploma thesis aims to follow up on the bachelor's thesis "Conduction of electric current and signals in agricultural tractors" and expand the reader's insight into the possibility of cable harness design using software tools and 3D software to visualize it on the overall machine model. At the beginning of the diploma thesis, the reader is acquainted with new trends in the management of electricity and communications in agricultural machinery, including trends in the management of cable harnesses. The next part deals with software tools for the creation and visualization of cable harnesses focused on agricultural technology and their use in practice. On this basis, cable harnesses for agricultural tractors from the production of Zetor Tractors a.s. are designed and implemented. Furthermore, testing of conductors in the protective material of bundles (protective hoses) for vibration resistance will be performed due to their internal filling with conductors. On this basis, cable harnesses will then be designed according to new trends and test results. These cable harnesses will then be part of the new production of Zetor Tractors a.s.

Academic dishonesty and its relationship to work ethics
Horák, Lukáš ; Preiss, Marek (advisor) ; Krámský, David (referee)
The thesis is concerned with possible relationship between the rate and kinds of academic dishonesty and work ethics. In the first segment of the theoretical section of the thesis, the extent of present research concerned with the reciprocal relationship of breaking of the rules in the context of school and work and the possibility of predicting aspects of work ethics on the basis of having knowledge about the rate of academic dishonesty of a given individual, is summarized. The second theoretical segment is a descripitiona and discussion of research of factors which affect both dishonesty in the school context and aspects of work ethics. On the basis of identification of these factors are in the empirical section analysed data, which were acquired through surveying of university level and high school students. Significant difference betwen the rates of dishonesty in high school and university level context, which is contradictory to some of the previous research literature.Relationship of the students to their grades and to some extent, gender, were shown to be significant influence on rate of academic dishonesty. The analysis of the direczt relationship between academic dishonesty and work ethics has yielded mixed results, suggesting, that the relationship si more complex than previously suspected

Using of ISA 95 for part of the production line
Horák, Lukáš ; Knobloch, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis deals with the design and implementation of the ISA-95 standard on a newly created production line. The standard and its models are described in the theoretical part, following with the individual selected software solutions, which were used for the standard’s application. Subsequently, a description of the construction and program tools of both devices, which by physical arrangement and their connection create the production line, is provided. The next part of the thesis deals with the design and application of a batch control process. This is the basis for an ISA-95 standard implementation, which uses specific software resources for data acquisition and visualization. A functional verification of the production line and realized design was done within the last part. The conclusion presents an evaluation of production based on analyzed data from the test production.

Vedení elektrického proudu a signálů u zemědělských traktorů
Horák, Lukáš
The aim of this bachelor thesis is to introdukce the possibility of modernizing part of the wiring installation in the mass-produced Zetor tractor to the reader. At the beginning of the work, the reader is acquainted with the basic principles of the elect-ric current itself, its flow, specifically in the design and construction of cable harness. Here are also described the most common requirements for the construction of the harness itself, from the design of the conductor and its insulation to the creation of cable harness. Also included is a section dedicated to the actual production of a par-ticular cable harness in a specialized company, including its testing during produ-ction and before its shipment to the customer. The conclusion deals with the imple-mentation of the newly designed cable harness, including its comparison with the previous version and the economic balance.

Industry 40 Testbed Autonomous “Ice Crusher“ Cell
Horák, Lukáš
This article describes design and creating an autonomous cell called „ice crusher“ designed to be used as a part of Industry 4.0 testbed. The testbed is supposed to simulate a small factory and is used to demonstrate parts of Industry 4.0. The main task was to design the mechanical part of the cell and equip it with sensors. In the first part of the article is to describe the mechanical part that is designed in NX software. In the next part suitable electronics is selected. The electronics was selected so that it provides safe and reliable cell control, while being as simple and cheap as possible. The control unit fot the cell is PLC 1200 and as for visualisation a HMI touch panel made by Siemens was chosen. The control unit was programmed using LAD and SCL languages.

Design of mechanical, electrical construction and software equipment of autonomous cell "Ice crusher" for Industry 4.0 testbed.
Horák, Lukáš ; Benešl, Tomáš (referee) ; Pásek, Jan (advisor)
The goal of this bachelor thesis is design and construction of an autonomous cell on a production line with the purpose of being an „ice crusher“. The purpose of this cell is to be part of a Testbed. The cell will be controlled using a HMI touch panel and PLC 1200. Information about how much ice the cell should pour into a glass is stored in an NFC chip on the bottom of the glass. The first part of the thesis comprises of brief introduction to Industry 4.0 alongside with description of the default and current state of Industry 4.0 testbed. Another part describes mechanical and electrical design of the cell. Last part of the cell describes software of the cell alongside with description of testing and installing the cell to the testbed.

Microstructure of carbon black nanomaterials studied by X-ray scattering
Machovec, Petr ; Dopita, Milan (advisor) ; Horák, Lukáš (referee)
Název práce: Studium mikrostruktury uhlíkových nanomateriálů pomocí rentgenové difrakce Autor: Petr Machovec Katedra: Katedra fyziky kondenzovaných látek Vedoucí bakalářské práce: RNDr. Milan Dopita, Ph.D., Katedra fyziky kondenzovaných látek Abstrakt: Předkládaná práce se zabývá studiem mikrostruktury, struktury a reálné struktury turbostratického uhlíku a uhlíkových nanotrubic pomocí metod rozptylu rentgenového záření. Klastry turbostratického uhlíku jsou popsány pomocí sady fyzikálních parametrů. Pomocí počítačových simulací je popsán vliv těchto parametrů na výslednou rozptylovou křivku. Dále je předkládán popis dvou typů uhlíkových nanotrubic a je popsán vliv typu a rozměrů uhlíkových nanotrubic na výslednou rozptylovou křivku. Pro experimentální část práce byla připravena série vzorků turbostratického uhlíku žíhaného při teplotách 300℃, 600℃, 800℃, 1000℃, 1200℃, 1400℃ a 1800℃. Pomocí maloúhlového rozptylu rentgenového záření byla určena velikost nanočástic a jejich rozdělení, velikost mikropórů, specifický povrch a dimenze povrchového fraktálu. Další fyzikální parametry jako velikosti a rozdělení velikostí klastrů La a Lc turbostratické uhlíku, mřížové parametry a a c a střední kvadratické výchylky atomů ve směru grafenových vrstev a ve směru kolmém byly určeny z širokoúhlových rentgenografických...
