New methods for super-resolution imaging
Kučera, Ondřej ; Rajmic, Pavel (referee) ; Špiřík, Jan (advisor)
This master's thesis deals with methods of increasing the image resolution. It contens as a description of theoretical principles and description of calculations which are wellknown nowdays and are usually used for increasing image resolution both description of new methods which are used in this area of image procesing. It also contens a method which I suggested myself. There is also a description of methods for an evaluation of image similarity and a comparation of results from methods which are described in this thesis. This thesis includes implementations of selected methods in programming language MATLAB. It was created an application, which realizes some methods of increasing image and evaluate their results relation to the original image using PSNR and SSIM index.
Colour image histogram processing
Kučera, Ondřej ; Číka, Petr (referee) ; Říha, Kamil (advisor)
This bachelor thesis deals with processing of colour image histogram. To better undestanding of this problem it describes individual methods which edit colour image and its histogram. The thesis suggests a program implementation which allows processing of colour image and its histogram.
Business Plan - Establishment of a New Company
Kučera, Ondřej ; Novák, Zdeněk (referee) ; Rompotl, Jaroslav (advisor)
This thesis focuses on drafting a business plan to establish a tailoring business. The work includes basic theoretical knowledge which is then transferred and applied into practice. In this work we can find multiple analysis of the enterprise environment or even an economic evaluation.
Fuel Properties: Proximate Analysis of Solid Fuels
Kučera, Ondřej ; Elbl, Patrik (referee) ; Musilová, Petra (advisor)
The bachelor thesis deals with the use of biomass as an alternative energy source and proximate analysis of solid fuels. In the theoretical part there is a research on energy utilization of biomass and a proximate analysis of solid fuels. Individual methods of determination of proximate analysis are described in detail, namely determination of water, ash and volatile combustible content and determination of gross calorific value. The practical part presents results of analysis of selected locally available plant biofuels. The methods of proximate fuel analysis have been successfully applied.
Residential complex Brno Holasky, V Aleji locality
Kučera, Ondřej ; Kopáčik, Gabriel (referee) ; Sátora, Josef (advisor)
The diploma project topic is development of the area "V Aleji" in Brno. The project designs housing in city, which should reflex current needs of city residents.
Analysis of welded joints after fatigue tests
Kučera, Ondřej ; Doubrava, Marek (referee) ; Havlík, Petr (advisor)
This bachelor thesis deals with analysis of welded joints after fatigue tests . The first part of this thesis, literary research, discusses weldability of carbon steels and low-alloy steels and effect of chemical composition on weldability of materials. Further there are zones of welded joints, their microstructure and mechanisms applied described in this thesis. There are defects occurring in welded joints and their common causes and remedies described in the part of literary research dealing with defects. And the final part of the literary research deals with material fatigue, fatigue of welded joints and effect of defects, fusion zone and heat-affected zone on the fatigue of welded joints. In the experimetal part of bachelor thesis there is described experimental material, results obtain process and discussion of results.
Realization of educational problems based on experimental apparatuses with oil and air lubricated bearings
Kučera, Ondřej ; Veselý, Oldřich (referee) ; Vaverka, Michal (advisor)
This master thesis is focused to make education exercise on simulation equipment, tilting pad apparatus and air bearing apparatus. Exercise are, for better understanding problems, completed about exercise measurement viscosity. Were to be proposed three separate exercise for exercising, which were to be well – tried. Measured data from stations for sliding bearing will students confront with computed data. To every exercise are created instructions for exercising, educational presentation and poster to arrangement.
Creation of GUI Designer for iTP (iNELS Touch Panels)
Kučera, Ondřej ; Šála, Jakub (referee) ; Drahanský, Martin (advisor)
This thesis is concerned with creation of designer for graphical user interface used in mobile devices. The application for these devices will be used for controlling system of intelligent electroinstallation. The thesis describes an existing solution of an intelligent electroinstallation provided by ELKO EP, s.r.o. It also contains detailed design of a prototype of an application to be used on mobile device and a desktop application used for graphical design.
L-band antenna and low noise amplifier
Kučera, Ondřej ; Lukeš, Zbyněk (referee) ; Záplata, Filip (advisor)
This master thesis is dealing with a system for receiving meteorological images from satellites placed on lower orbit. Furthermore it gives basic information about satellites NOAA, METOP and FY. It also includes derivations of equations, that define minimal requirements for receiving antenna and LNA. From reached parametres, energetic balance for connection of the satellite and Earth is calculated. The main part of the master thesis is designing of low-noise amplifier for L band. LNA is implemented on the substrate FR4 and Arlon DiClad 870, circuit is designed with elements of parametres, which are spread out or concentrated. The last part of the thesis describes design of antenna for reception of meteorological images.
Four-cylinder in-line gasoline aircraft engine
Kučera, Ondřej ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The thesis deals with the structural design of a steel connecting rod for the aircraft engine Walter Mikron III, which is currently still manufactured and developed by company PARMA-TECHNIK, s.r.o. The proposed connecting rod would replace the current duralumin connecting rod. The work also contains a strength analysis of the designed component, in which it was aimed to verify the stress on the connecting rod, based on which the fatigue safety factor was performed. This is crucial for dynamically stressed parts of internal combustion engines. Furthermore, was investigated the effect of the change of the connecting rod on the torsional vibration of the crank mechanism. For this purpose, was built a discrete torsion model. The output of the whole work is the drawing documentation of the new connecting rod, meeting the requirements for application in an aircraft engine.
