Design of automatic multichannel pipetting head
Suchý, Adam ; Holoubek, Tomáš (referee) ; Cejpek, Zdeněk (advisor)
The goal of the diploma thesis is to make a multi-channel pipetting end effector , which could be used with a collaborative robot YuMi IRB 14000 from ABB company. The main task is to ensure the precise dosing of the liquid medium by using the pneumatic piston approach. The next phase of the thesis requires the production of a functioning prototype with a control system for the proposed device with the help of a 3D printer , whose functionality needs to be tested along with the cooperative robot YuMi.

Machine Vision: Support for Lab Applications
Starý, Vojtěch ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
This diploma thesis deals with machine vision problematics and its use for laboratory applications. Machine vision is basically the substitution of human vision for machines using a video camera and a computer. The essence of this thesis is a brief review of machine vision and the issues associated with machine vision systems and brief description of hardware, software and algorithms used for this work. Implementation of machine vision on Raspberry Pi and Cognex platform. Connection of the Raspberry Pi platform with a parent platform (automaton, robot) and subsequent evaluation of the solution.

PetNetSim Library Computation Performace Optimization
Dražka, Vojtěch ; Holoubek, Tomáš (referee) ; Dobrovský, Ladislav (advisor)
The aim of the thesis was to optimize the computation speed of the PetNetSim library, which is currently implemented in Python. The purpose of the thesis was to approach the optimization from a broader perspective and try to speed up Python using various techniques. The thesis explores the solutions available in the form of alternative interpreters, extending modules, trans-compilation methods and the possibility of developing the computational core as a module written in the system language. The practical part describes efforts to implement these methods and their comparison. Furthermore, the multiprocessing method is implemented and the procedure for developing the computational core as an extending module is outlined.

Legal regulation of the status of political parties in the Czech Republic
Holoubek, Tomáš ; Jirásková, Věra (advisor) ; Hřebejk, Jiří (referee)
1 Abstract The aim of the thesis is to present a comprehensive picture of the legal regulation governing the status and activities of political parties in the Czech Republic, to point out its weaknesses and, where appropriate, to present de lege ferenda proposals. The thesis is divided into four parts. The first part deals with the general development of modern political parties and the reasons that led to their institutionalization. Then, it presents the development of the legal regulation of political parties in the Czech lands, starting with the revolutionary events of 1848 and 1849 and ending with the establishment of the independent Czech Republic. The quasi-institution of political movements, whose presence in the legal system cannot be defended in any way, is also presented. The second part deals with the constitutional incorporation of political parties. At the constitutional level, the privileged role of political parties in the political system is explicitly recognised. Safeguards for the free development of political parties are enshrined here, but also their obligation to respect fundamental democratic principles. The third part deals with the legal regulation of the most important aspects of the life of political parties - the issues of their formation and dissolution, the regulation of...

VISUAL INSPECTION OF WELDING OF PLASTIC SQUEEZE TUBES
Furik, Pavel ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
Bachelor’s thesis deals with machine vision systems in order to inspect plastic squeeze tube seals. Principle and options for choice of vision systems are summarized in theoretical part of the thesis. Based on this summary, a selection of vision system and inspection application design was to be created that would inspect selected parameters of plastic tube seals. This design was to be tested and evaluated by behavior of system with varying contrast.

Machin vision-based inspection of embossed texts and patterns on tubes
Záhorský, Patrik ; Holoubek, Tomáš (referee) ; Škrabánek, Pavel (advisor)
Bachelor thesis deals with the inspection of embossed text and patterns on plastic tubes using machine vision. Part of the work is a research part, which deals with the composition of machine vision systems and its tasks in industry, the method of digital imaging, properties, technology and use of individual system components, including a description of technical and software tools for data processing. Subsequently, the solved tasks are specified and the monitored objects are described. The design of the system consists of a description of the hardware components, their interconnection, selection of a suitable geometry and implementation into a complete assembly. The following is a proposal for solutions for specified tasks, which describes the selection of individual algorithms and the setting of their parameters. Finally, the implemented solution is tested on two different sets of samples and the results are accordingly evaluated.

Ninepin Bowling Automata – elevator and ball thrower
Robota, Jakub ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
The goal of this master’s thesis was to design and construct ninepin ball elevator for automated pin setter machine and ninepin ball launcher to simulate load and to verify correct function of the setter machine. Also, a ball track was designed as a means of transport for the ball from elevator to launcher. Theoretical part of thesis contains research into ninepin bowling, its rules and analysis of different applicable solutions found on the market that deal with automated pin setters and their ball elevators. Furthermore, a separate research into ball launchers was conducted. Practical part of thesis was comprised of own solution to design and construction of elevator, which extended already designed pin setter machine. After this, track for ball was designed and constructed together with ball launcher which imitates load that would the machine experience during usual game.
