Preparation of the company project for financing by the help of funds EU
Svoboda, Petr ; Mucha, Jan (referee) ; Mandelík, Petr (advisor)
Preparation of the company project for financing by help of Structural funds EU One of a few centrally administrated possibilities of how to help a domestic company stand very tough fight on the market is to make use of financial resources provided by EU budget as a help in development of the entering members. These are variant sources that can be obtained despite the very complicated system of administration and that can be used to replace (or to replenish) primary financing e.g. loans or one’s own resources. Within the framework of published appeals for bringing forward the projects, conditions related to supplying these financial means and according to the purpose of these supporting programmes there are several possibilities of financing of our company. This thesis concerns the financial preparation of a project of a small company based on EU structural funds and their proclaimed appeals of Ministry of Industry and Trade. A detailed analysis of the company’s situation as a general base for entrepreneurial projects is accomplished. This analysis is followed by the project appropriate for the application to the administrator.

Antennas for milimeter-wave bands
Pítra, Kamil ; Svoboda, Petr (referee) ; Raida, Zbyněk (advisor)
This thesis describes design and experimental verification of three types of the wideband antenna Bow-tie antenna, Vivaldi antenna and Spiral antenna. The tracked parameters are bandwidth, input impedance, gain and directivity patterns. Next step is design of millimeter-wave horn antennas. Attention is turned to the proper construction of a wideband feeder of the horn. For the final antenna structure, a bow-tie dipole and a Vivaldi antenna were chosen. The antenna construction is aimed to provide a wide bandwidth on one hand and a high gain on the other hand.

Design of clamping device for mass production on CNC milling machine
Blahuta, Jiří ; Foltýn, Jan (referee) ; Svoboda, Petr (advisor)
This bachelor thesis deals with a design of a milling fixture and a fixture for broaching on a press. The fixtures enable progressive production on a CNC machine with a high efficiency and minimal downtime. The fixtures are designed for a serial production of a specific component in automotive industry with quantity of 250 000 units per year. The main goal and partial goals of the thesis were accomplished. The designed milling fixture uses wedge clamps and hydraulic cylinders for clamping. The broaching fixture uses springs to position the workpiece. The design of proposed fixtures was verified by production capacity calculations, which prove that the series will be produced in a required time. To further increase productivity, it was suggested based on calculations to use five milling fixtures in the milling machine. The design of the broaching fixture was verified by FEM simulation, which showed that the device is sufficiently rigid and strong. The result of the work is a design of two fixtures in the form of 3D models and drawings. The work includes, among other things, research of three-axis CNC milling machines, broaching machines, and wrought aluminium alloys.

Effect of Noise on Image Compression
Pavlík, Jiří ; Svoboda, Pavel (referee) ; Bařina, David (advisor)
This thesis examines effect of different types of noise on performance of significant image compression formats. Three different types of noise are examined, Gaussian noise, Gaussian noise with bigger granularity and shot noise. Two older loosy image compression formats JPEG and JPEG 2000 are compared with newer format WebP. This examination is based on results of experiments with images, which are intentionally degraded by noise, then compressed to examined formats and compared with result of experiments for original images without noise. The effect of noise on performance of comparised formats is based on image quality metric SSIM. From results of experiments, Gaussian noise with bigger granularity seems to be the least distruptive from all types of noises. The other two types of noise have much more dwindling effect on quality of images.

Film thickness distribution during the start-up of smooth surfaces.
Manga, Martin ; Křupka, Ivan (referee) ; Svoboda, Petr (advisor)
Bachelor thesis is engaged in experimental study of start-up of smooth surfaces under the conditions of mixed and elastohydrodynamic lubrication. Start-up is non-stationary process, whereat the surface doesn’t need to completely separated with lubrication film. Therefore it exists a real risk of failure. Study summaries all present studies and extends with own experiment on the equipment of tribological laboratory. The evaluation of the experiment was made by chromatic interferometry. This method is used to measure thin lubrication films. Experiment for miscellaneous values of acceleration confirms the findings of previously studies.

Weldet constructions in technical documentacion
Bartošek, Daniel ; Brandejs, Jan (referee) ; Svoboda, Pavel (advisor)
The presented bachelor´s thesis deals with design documentation of welded con-structions. It provides an overview of weldment design types, basic usage principles and formal prerequisits. The thesis should serve for education of weldment design documentation, for which purpose the set of tasks included in the annex was also created.

Design of surface texturing experimental rig
Bouma, Adam ; Svoboda, Petr (referee) ; Šamánek, Otakar (advisor)
The aim of this thesis is mechanical indenter design, mainly two basic parts of this apparatus. The introductory section describes the basic techniques of mechanical surface texturing of engineering surfaces. The second part deals with the particular design of the device. It also describes the strength control of loaded components. The economic evaluation is given at the end.
