The Tool for a Radial Expanding of Tubes by Liquid
Horák, Michal ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
The submitted diploma thesis is focused on problematic of a radial expanding of tubes. In the first part of thesis, there is a summary of possible theoretical formulas for determining the stress-strain material parameters for biaxial bulging test of tube by liquid. Also there are showed several options for testing tools used in research abroad. The work also contains technological and control calculations for the selected test sample from the tube of steel 17 240 (1.4301). At the end of thesis, there are key points for tool design and there is also presented the proposed the test tool for a radial expanding of test sample of tube to the free space and with firmly fixed the ends of tube in the tool.

Demonstration of Marked Graphs Features
Horák, Michal ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This thesis presents Petri nets as a modelling tool, defines their features and subclasses, including marked graphs. The goal of this paper is to inspect the features of Petri nets by analyzing their state space. As the output of this thesis, a tool for analyzing the features will be designed and implemented, with potential to extend the usability of Petri nets.

Study of the electron optical systems with broken rotational symmetry
Horák, Michal ; Radlička, Tomáš (referee) ; Zlámal, Jakub (advisor)
This thesis deals with computing of the magnetic lens with a perturbed pole piece due to manufacturing imperfections. Two possible ways of calculation are discussed - the perturbation theory and 3D computing. Three methods for evaluating axial multipole field functions from 3D fields are introduced. Beam spots in the image plane and aberration coefficients are computed and results obtained by the application of perturbation theory are compared to results evaluated from 3D simulations. Consequently, a suitability of using the perturbation theory is discussed.

Design of General Service Crane, used for manipulation on the deck of the vessel
Dlužanský, Tomáš ; Horák, Michal (referee) ; Pokorný, Přemysl (advisor)
This master's thesis makes a brief comparison of design variants of cranes for general use on the deck of a vessel. Further, this thesis deals with a design of a crane with a telescopic jib and a single knuckle. An important part of the crane’s design is its kinematic solution, which was modified in the design phase. The last step of a simplified analytical calculation of the jib for design steel construction is given. This preliminary calculation is the starting point for a FEM model and for the following FEM analysis. A stress control is made according to the Lloyd's Register of Shipping agency’s standard for lifting appliances in marine environment and also according to the recommendations of Huisman company. A part of the proposed solution is a selection of main components of the crane. The master’s thesis contains a summary of some operational and other information which characterize possibilities of the crane’s use. This thesis also includes source materials for drawing documentation.

Design of truss jib offshore crane
Palatinus, Peter ; Horák, Michal (referee) ; Pokorný, Přemysl (advisor)
This master`s thesis deals with the design of an offshore crane jib with maximal safe working load 80 tons and maximal radius 45 meters. The design consists of a design solution of the steel construction and a stress analysis of its FEM model, which was performed using NX I-deas software according to the requirements and specifications of the Huisman company. This thesis includes source materials for drawing documentation.

Static and dynamic properties of current sources
Čech, Vojtěch ; Boušek, Jaroslav (referee) ; Horák, Michal (advisor)
The goal of this thesis is to describe the main attributes of current sources and their use as current mirrors. It is focused on the most common variations, and is specially targeted the principles and features of the Wilson-current-mirror, which is composed of bipolar and unipolar transistors. The goal is to compare them, on the basis of the analysis.
