Control Electronics for Electromagnetic Ball Accelerator
Dočkal, Tomáš ; Harvánek, Michal (referee) ; Král, Jan (advisor)
The goal of this bachelor's thesis was the design and implementation of an electromagnetic accelerator for a steel ball in a closed circular track. Electromagnetic accelerator serves as a demonstrator of particle accelerator functionality and as a game with the aim of engaging students in the study of electrical engineering. The work includes designing the coil using an algorithm in Matlab, which optimizes parameters to achieve maximum magnetic field intensity while considering limited power loss and voltage. The power electronics were designed and the functionality of the circuit concept was verified through simulation. The printed circuit board (PCB) for the power electronics, which also includes the control unit, was designed in KiCad. The system incorporates both passive and active cooling and is equipped with temperature sensors to ensure safe operation. The control part of the system was designed using the ESP-WROOM-32 development module, which allows for remote control and monitoring via a web interface. Optical sensors were designed to enable precise detection of the ball's position and speed. The mechanical part includes the fabrication of the coil frame and the mounts for the optical sensors using 3D printing. The PCB, along with the power supply, was mounted in a casing.

Control system for assembly and test automatic machine for electronics of car seats
Dočkal, Tomáš ; Zemánek, Pavel (referee) ; Pásek, Jan (advisor)
The thesis deals with definition of safety, traceability systems, creation of PLC programs for testing device control system and creation of Operator panel software. The thesis is divided into the machine specification and description, OP function description including function keys and the description of the control system with samples of the completed PLC program. The PLC program is written in STL and FBD language in STEP7. The conclusion describes functionality of the device.

Automatic control of watering system
Voda, Petr ; Dočkal, Tomáš (referee) ; Pásek, Jan (advisor)
This work deals an automatic watering control system for a total of 12 sections of the garden. The main requirements for the system, is the variability adjustment watering and the possibility service control. Watering control will provide PLC with distributed inputs and outputs, control and visualization will be realized HMI. I designed a sophisticated system that allows user to adjust watering in particular days of the week and the required times with an optional length watering for each section separately. There is the service mode that it possible to control the individual actuators without any restrictions and conditions. The main advantage of the system is variability watering, which allows reuse without greater changes of the program.

Receivables Management in Corporation
Dočkal, Tomáš ; Apko, Martin (referee) ; Pěta, Jan (advisor)
This bachelor thesis is focused on the issue of management of trade receivables in a business corporation, especially on receivables after the due date. There are described methods how to prevent these claims and how to solve them in case of their origin. Theoretical knowledge is applied on the example of a real capital trading corporation.

Solidarity in legal obligations
Dočkal, Tomáš ; Švestka, Jiří (advisor) ; Salač, Josef (referee)
Summary. In this thesis there is treated legal institute solidary obligation relationship. It is one of that legal institutes which are not in the limelight of as many specialized works as they should be for their frequency of their use in practice. Although it could seem at first sight that the solidary obligation relationship is formed enough that there cannot arise any faintnesses there, but the opposite is true. There is not a one united theoretical view of solidary obligation relationship; the solidary obligation relationship can be understand as a one obligation relationship by the first view called theory of unity, but it can be understand as more obligation relationships which exist between creditor and every solidary debtors (in case of passive pluralism) or between debtor and every solidary creditor (in case of active pluralism) by the other view called theory of plurality. The most of specialized literature which take heed of solidary obligation relationship and which were written in recent time understand the solidary obligation relationship in accordance with the theory of plurality. This thesis in opposite to that specialized works understands solidary obligation relationship as a one obligation relationship in accordance with the theory of unity which is preffered in practice although it is...
