This bachelor thesis deals with ways for emission reduction of passenger cars with an ignition engine. The introduction describes the principle of combustion, the methods of preparation of the ignition mixture and pollutants that arise during the combustion. In the main part of the work, the individual specific provisions for reducing emissions used in modern vehicles are analyzed in detail. Further the examples of current emission systems for several selected cars are presented. All the findings are summarized in the following chapter. In the next part, own configuration of the emission system is described in detail, which is designed with the regard to maximum efficiency in reducing emissions. The summary together with the evaluation of the current situation and the outline of the possible direction for further development in this area are in the last part of this work.

Production of supporting plate
Filip, Jiří ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of technology for production of supporting plate, which is a top part of a service trolley, serving for manipulation with switch of high voltage. The supporting plate is manufactured of low carbon, deep drawing steel DX51D+ZM thickness 2 mm and quality according to EN 10346. Annual serie was set for 200 pieces. In evaluation of production possibilities were chosen technologies of punching and bending. There was designed unfolded shape of the sheet metal with dimensions 1068 x 900 mm and created cutting plan. As was found, from one metal board is possible to cut out 2 pieces of the supporting plate, while 70% of material use. In the next step, punching tools were chosen and manufacturing process was made. The highest achieved cutting force was 122,8 kN. The chosen machine is hydraulic CNC press TruPunch 5000. For bending there was created a bending plan, according to which bends will be made in thirteen steps. Used bending tools are punch OW209/S and two types of matrix EV005 + FWZ and EV006 + FWZ. Maximal achieved bending force is, according to the calculation, 259,8 kN. Bending operations will be made on CNC press TruBend 5130. In a technical and economical evaluation was determined cost for the material, which is 57 337,5 Kč.

Virtual commissioning of the automatic assembly of the stepper motor
Filip, Jakub ; Vetiška, Jan (referee) ; Szabari, Mikuláš (advisor)
The diploma thesis deals with the virtual commissioning of a robotic workplace designed for the assembly of parts of NEMA stepper motors 14, 17 and 23. The theoretical part is devoted to research in the field of industrial robotics and virtual commissioning. Furthermore, an analysis of the problem is performed, on the basis of which variants of the robotic workplace are proposed. Then, these are subjected to multi-criteria analysis, which is used to select the resulting concept. This concept is processed as a 3D model and virtually put into operation, thanks to the resulting line cycle is determined.

Boďa, Michal ; Filip, Ježek (referee) ; Pásek, Jan (advisor)
The main object of my semestral work is to diagnose communication of devices on the network Profibus DP. Consequently to signalize potential failures such as disconnected device or partially wrong connection of device. Signalization will be running on touch screen of operating panel. In the first part of my work there are the networks described, in which the system will communicate and also summary description of equipments which will be diagnosed. In the next part of my work there is description of diagnosed program and flowchart. In the last part, my semestral work is talking about visualization of diagnostic program, collocation of windows and of entire design.

Design and implementation of control program for mobile robot platform Turtlebot3 Burger
Filip, Jakub ; Lacko, Branislav (referee) ; Parák, Roman (advisor)
The aim of the bachelor thesis is the design and implementation of a control program for the mobile robotic platform TurtleBot3 Burger. The theoretical part of the bachelor's thesis defines the issue of mobile robotics, with a closer look at the various possibilities of locomotion, including examples from industrial practice. The TurtleBot3 mobile robot series belongs to the robotic platforms distributed by ROBOTIS, where their main feature is compatibility with the Robotic Operating System (ROS). The core of this system is licensed under the BSD, which guarantees open source code. The integration of ROS with the TurtleBot3 Burger model provides freely accessible robust libraries, which form the basis for understanding the control of a differentially controlled robot through ROS. In the practical part, the assembly and configuration of the robotic kit TurtleBot3 Burger is performed, including the introduction of key functionalities of this mobile platform, and the design of your own solution. The conclusion contains the justification of the mentioned proposal and the output after its implementation on a real robot.

Tooth Detection on Jaw 3D Computer Polygonal Model
Filip, Jan ; Šiler, Ondřej (referee) ; Kršek, Přemysl (advisor)
Aim of this bachelor thesis is a proposal and an implementation of a tool for the tooth detection on a 3D computer polygonal jaw model, which will allow to a user to obtain the shape of teeth on the jaw. This tool should to help in the stomatology. In the event of any inaccurary in the detection it will be possible to change certain parameters and methods, by which will be possible to influence the accuracy of detection. Program will import models in the STL format and subsequently will allow to the user to see the result of the detection in a browser. Teeth detection models will be possible to export single or together, in the STL format. The implementation language will be C++, compiler GNU C in distribution MinGW, toolkit to work with the 3D model will MDSTk and primarily its part VectorEntity. For imaging of thr 3D scene will be used OpenSceneGraph toolkit. Application will be developed primarily for MS Windows operating system but thanks to using GNU tools should be portable at the level of source codes to anothers operating systems.

Effect of cutting inserts surface treatment on turning durability of stainless steel
Filip, Jiří ; Vítek, Jiří (referee) ; Sedlák, Josef (advisor)
The diploma thesis deals with the testing of coated carbide inserts with different types of surface treatments. The testing was conducted using longitudinal turning technology under constant cutting conditions, and the workpiece material used was austenitic corrosion-resistant steel. The aim was to analyze the wear progress of the cutting edges after predetermined time intervals and to determine the resulting durability of the tested inserts. During the testing, the cutting edges of the tools broke off and the required durability was not achieved. After a thorough examination of the workpiece material, a significant amount of unevenly distributed inclusions was found in the steel structure, which proved to be the main cause of the insert breakage. Therefore, it was decided to perform a replacement test using material from a new supplier. Material analysis of the newly delivered steel showed a significantly better purity of the structure, which was positively reflected in the results of the second test, in which there was no brittle fracture of the edge in any case and the tested samples reached the required durability. The best results were obtained with samples treated on flanks using a new surface treatment method developed by Dormer Pramet s.r.o. After completing the tests, an adhesion test of the coating to the tool substrate was performed using the Rockwell method. Based on microscopic images that revealed partial delamination of the coating, it was evaluated that the quality of the deposited layer was not quite optimal. In a technical and economical evaluation were determined the potentially saved costs when using the experimental cutting insert compared to the reference plate A.
