Transfer and interpretation. Expatriation of Czechoslovak citizens of German birth 1945-1947 and its accounts in daily newspaper
Klimeš, David ; Bednařík, Petr (referee) ; Kubů, Eduard (advisor)
The aim of my thesis is to analyze the transfer of the Gennan people as covered by the daily press, which was both partisian and officially considered not to be under the influence of the political parties. Among such newspapers were Právo lidu, Svobodné Slovo, Rudé právo, Lidová demokracie, Svobodné noviny, Práce, Zemědělsé noviny, Svobodné československo (Obrana lidu), Mladá fronta and Národní osvobození. In fact, most of these "independent" newspapers were under control of the Communist Party. Resettlement of the Germans was one of the most important issues discussed by the Czech cabinet after the W orld War II. The transfer of the Gennans was obviousl y a genuine wish of the maj ority of the Czech people. However, following the first revolutionary months, a variety of opinions was being expressed on this issue. The Communists wanted to use the resettlement as a political instrument. Naturally, they were in favor of a total transfer of the Germans. On the other hand, other political powers expressed more moderate views, such as the catholic People's Party. The debate was broadly covered by the newspapaers. The media offered greater variety of perspective. There was a strong censorship by the establishment as well as by the journalists themselves, and no one dared to stand against the Košický program...

Design of an application for educational model of a manipulator with three degrees of freedom
Youssef, Daniel ; Křivánek, Václav (referee) ; Klimeš, David (advisor)
Tato práce popisuje další vývoj výukového sériového manipulátoru se třemi stupni volnosti. Práce se zabývá jednoduchou mechanickou úpravou manipulátoru, ale především pak softwarovou částí. Výsledkem je pak hra piškvorky, kdy manipulátor umožňuje hru proti lidskému protějšku. První část práce je věnována zlepšení inicializačního procesu manipulátoru a následně pak i návrhem vhodné polohové regulace. V další části je manipulátor rozšířen o jeden stupeň volnosti. Součástí je i návrh koncového efektoru vhodného pro psaní. Z takto upraveného manipulátoru je sestaven kinematický model vhodný pro real-time řízení. Dalším krokem v práci je návrh samotné aplikace hry piškvorky. Je navržen vhodný hrací algoritmus, včetně detekce a rozpoznání znaků v hracím poli pomocí kamery. Následně je vše implementováno do real-time aplikace, kde komunikaci s uživatelem zajišťuje navržené uživatelské rozhraní.

Computer vision and stereo vision
Bubák, Martin ; Klimeš, David (referee) ; Vejlupek, Josef (advisor)
This dissertation work is describing the usage of the software tool Computer Vision System Toolbox to create applications in computer vision. At the beginning of the work is performed background research of image scanning and its representation by using colour models. It is followed by a description of epipolar geometry and lastly is stated a description of the Computer Vision System Toolbox. In the next section of the work we deal with setting of used Basler cameras and processing of the scanned image. The following is a description how to create applications for object detection and after this description, we get to know applications for creation of depth maps area.

Extending the functionality of educational robotic manipulator
Nejedlík, Tomáš ; Šubrt, Kamil (referee) ; Klimeš, David (advisor)
This thesis deals with extending the functionality of robotic manipulator. The main objective is the implementation of control algorithms into microcontroller dsPIC. In the first part, realizable modifications on the manipulator are described. Touch end sensors are replaced by touch less Hall sensors. End effector, which is used for writing, is replaced by gripper for moving items. Another section deals with design PCB with microcontroller and it describes the final program. The last part deals with connection intelligent touch display, which is used for controlling the manipulator. Demonstration application is created to show the use of the display and new end effector.

Design of control unit for two-wheeled self-balancing vehicle
Bastl, Michal ; Klimeš, David (referee) ; Chalupa, Jan (advisor)
This diploma thesis is a part of a project of two students. The aim of the project is to design safer electronics for the unstable balancing vehicle HUMMER and implementation of advanced diagnostics and fault detection. In the first part of the project we analysed the original vehicle using the FMEA analyse and created a new concept of the vehicle. The second part of the project describes a new hardware. I designed and tested the power electronics, control unit and supplies. The outputs of the work are prototypes which allow testing a new concept.

Hardware and software solution for diagnostics and safety operation for robotic manipulator
Klimeš, David ; Kubela, Tomáš (referee) ; Grepl, Robert (advisor)
This thesis deals with design and use of manipuilator with three degrees of freedom. The main objective is to develop appropriate educational platform. Firstly, it deals with definition of the goals and design method based on kinematic and dynamic models. Another section is dedicated to the design and implementation of the electronics needed for the safe and reliable operation of the manipulator as a educational platform. The last part deals with the use of manipulator together with additional sensors as well as vision system. The result is a demonstration of tasks use of manipulator. Example of use of this educational platform is implemented in a few demonstration tasks.

Testing parameters of stepper motors at different microstepping mode
Műller, Jakub ; Chalupa, Jan (referee) ; Klimeš, David (advisor)
This thesis deals with design and construction of test equipment that allows measurements of basic parameters of stepper motors. The first part is devoted to the search about the principle of operation of the hybrid stepper motor. For the analysis engine has been used a mathematical simulation model with real parameters in Matlab/Simulink. The next section is the design of mechanical and electronic form of the test facility with a description of the components used. The last part of this work is focused on measuring the excitation currents and measuring loss of steps at various control modes and microstepping.
