MR imaging of somatic embryos
Chovanec, Ján ; Kubásek, Radek (referee) ; Bartušek, Karel (advisor)
The aim of this bachelor thesis is measuring of tissue cultures of spruce MR imaging methods. Was measured set of samples, where was found contain of cluster in each cuts. To obtain the image, the magnetic resonance was used, specifically spin echo sequence. Method called spin echo is based on two pulses 90° and 180°. Selected method from the beginning of the work is than used to measure the diffusion and processing of cultures. In last part the work is devoted to data processing in Matlab and Marevisi.

Feasibility Study of Project
Šimko, Vladimír ; Chovanec, Ján (referee) ; Koleňák, Jiří (advisor)
The Master’s Thesis deals with project management issues in the field of energetic, specifically diversification of fuel base with usage of renewable resources. The thesis is divided into two parts, from which the first part is focused on theoretical background of project, project management and feasibility study issues. In the second part particular feasibility study is elaborated. The goal of this thesis is to create feasibility study, which is one of the requested appendixes of grant application.

Multiparametric segmentation of MR images
Chovanec, Ján ; Šmirg, Ondřej (referee) ; Dvořák, Pavel (advisor)
The aim of the thesis was familiarity of segmentation methods for automatic segmentation of MR images, using multiparametrical display. The theoretical part focuses on the description of methods of segmentation techniques. In the practical part are implemented K-means and level-set method. The methods are tested on the images of the brain obtained by different sequences (T1, T1c, T2, FLAIR). Segmentation methods are implemented in the program MATLAB. Implemented segmentation accuracy is demonstrated on data which there are reports reference results. Evaluation methods is performed using different classifiers decision. The K-means method is tested different metrics and different combinations of the input image. Finally, both methods are compared with one another and visually evaluated against the reference image.

Weather measurement
Chovanec, Jan ; Havránek, Zdeněk (referee) ; Bejček, Ludvík (advisor)
The achievement of this thesis is to design functional equipment which is able to measure the basic meteorological variables as air temperature, humidity and barometric pressure. In order to measure relative humidity completed with temperature, an intelligent sensor manufactured by Intersema Inc., MS5534B, was chosen. Relative humidity is measured by a capacitance sensor Humirel HS1101LF. The measured data are stored in anon-volatile memory. Data can be downloaded to a computer file via serial port or they can be online displayed on the computer screen via the wireless Bluetooth connection. Because the equipment is supposed to be used for the external measurement without the connection to electricity, low power consumption was considered as a most important parameter as well as good weather protection.

Laboratory railway model control
Šimík, Vladislav ; Chovanec, Jan (referee) ; Zezulka, František (advisor)
This work deals with possibilities of operating signals under the power supply voltage and using of this technology in guidance of a model of railway. Firstly there is an analysis of analogous and digital guidance of the model of railway. There is also a description of theory of three kinds of used modulations such as ASK, FSK and OFDM modulation. There are described only principles of those modulations because the problematic of the modulation is going to be solved by integrated circuit. The next part of this work is going to deal with a market research and with description integrated circuits, which ensure the modulation of operating signals of power supply voltage. There is also going to be noticed a description of others circuits that are needed for the correct function of the whole furnishing. Then I will continue with a project of scheme and single PCB for a guidance of the model of the railway. The last part of this work is concerned with activation and a proof of those proposed linkage.

Analýza možností energetického využití odpadů ve vybraném regionu
Chovanec, Jan
This thesis examines the possibility of using the energy potential of waste produced in Ostrava and its surroundings. The aim of this work is to determine whether it makes sense to build a waste incineration plant with energy usage. The thesis also deals with possibilities of heat utilisation, which is produced by the combustion of municipal waste. In the first part is evaluated quantity and composition of the produced waste. The methods of deliveries and the amounts of thermal energy in the selected area are described next. On the base of this information, the facility is designed. Finally, the possible contributions to the region are evaluated.

The development of "Blue Ocean" strategy concept
Šimek, Bohuslav ; Doucek, Petr (advisor) ; Chovanec, Jan (referee)
The strategic concept of "blue oceans" is currently undoubtedly one of the most interesting and most often talked strategic concepts. The thesis is therefore deals with the development of this strategic concept at the time and on the basis of previous papers of the authors in which were introduced tools and frameworks that later became part of the blue ocean strategy concept. The thesis also deals with other publications that the idea of the concept uses in own frames or in some way continues to build upon it. Further a description of the whole strategic concept is presented with each of analytical framework and tool with emphasis on additional context and findings of the section on the recent development of the concept. A key part of the thesis is the application of the concept to the three services - Knihovnička.cz Prezi and the Steam and evavulation of these tools with emphasis to the conclusions that have been made in the recent development of the strategic concept of "blue oceans" and its application.
