Charger for small accumulators
Dvořák, Pavel ; Zeman, Václav (referee) ; Kolka, Zdeněk (advisor)
Work will address the characteristics of small batteries. They are described types of charging process, charging time and charging currents, depending on their effectiveness. Great attention will be directed to draft Chargers, working in the area of continuous or discontinuous modes. Furthermore, the calculation of individual components and their influence on the running drive. The charger will be simulated by PSpice program and powered photovoltaic. Work will focus on the maximum efficiency when the incident light intensity. With related setting maximum efficiency and maximum power tracking using microprocessor-controlled detention. The charger will detect the input voltage, battery voltage and current. Depending on these values will be changed duty cycle PWM.

Object Description in Images
Dvořák, Pavel ; Šmirg, Ondřej (referee) ; Zukal, Martin (advisor)
This thesis consider description of segments identified in image. At first there are described main methods of segmentation because it is a process contiguous before describing of objects. Next chapter is devoted to methods which focus on description identified regions. There are studied algorithms used for characterizing of different features. There are parts devoted to color, location, size, orientation, shape and topology. The end of this chapter is devoted to moments. Next chapters are focused on designing fit algorithms for segments description and XML files creating according to MPEG-7 standards and their implementation into RapidMiner. In the last chapter there are described results of the implementation.

Small apartment house
Dvořák, Pavel ; Vacenovská, Veronika (referee) ; Utíkalová, Ivana (advisor)
The aim of this bachelor thesis is to elaborate the project documentation of a new-built small apartment building in Litohor. The apartment building is partially basement with three above-ground floors and one main entrance to the building. A total of eight residentail units and common areas for the residents of the building. The vertical loadbearing structures are made of ceramic masonry units. The horizontal loadbearing structures and staircase are made of reinforced monolithic concrete slab. The roof consists of a cut roof. Windows and doors are made of aluminium. The building will be heated by the heat pump. There are sixteen parking spaces in the ground.

Perfusion image processing
Dolníček, Petr ; Dvořák, Pavel (referee) ; Mikulka, Jan (advisor)
The goal of this diploma thesis was to create a script in MATLAB, which is capable to load DICOM pictures, read the data in their headers and then select the right series for perfusion analysis. This analysis is based on detection of contrast fluid in bloodstream and tissue and right interpretation of concentration changes of this fluid in time. This work is trying to describe a way of building an ultimate system capable of autonomous tumor analysis and classification. In the end, there is an analysis of DICOM sample performed by created script.

Segmentation of MR images using machine learning algorithms
Dorazil, Jan ; Mikulka, Jan (referee) ; Dvořák, Pavel (advisor)
This thesis concerns with magnetic resonance image segmentation using Random Forests algorithm. Employed technologies accomplishing the specified task include C++ progra- mming language with libraries ITK and OpenCV. This work descibes the technique of processing images from loading through preprocessing to the actual segmentation. The outcome from this work is a programme that automatically segmentates MR images of mouse’s head to the brain and the surroundings.

Chess Program with Various Chess Variations with Various Initial Arrangement
Dvořák, Pavel ; Žák, Jakub (referee) ; Rozman, Jaroslav (advisor)
This thesis focuses on describing required components in the process of creation of modern chess application. Goal is to create chess program with several chess variations using structures and algorithms based on professional chess programs. Thesis describes principles of chessboard representation and various factors of chessboard state evaluation used in classic chess and implemented variants. Finally thesis describes game-tree search algorithms and enhancements and compares their effect.

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.

Multifunctional building
Dvořák, Pavel ; Šobrová, Zdena (referee) ; Utíkalová, Ivana (advisor)
The aim of the diploma thesis is to elaborate project documentation of a new-build mixed-use building in Moravske Budejovice, in the cadastral area of Moravske Budejovice. The mixed-use building comprises a partial cellar and three floors above the ground. In the cellar, technical facilities and storage space for the residental part of the building can be found. The ground floor and the part of the first floor are designed for commercial premises, a hairdresser's, a florist's, a bookshop and a café. Residental unit consisting of three flats is located on the first and second floor. the building is made from 300 mm thick ceramic construction blocks with the external thermal insulation system. Ceiling construction is made of 250 mm thick concrete monolithic panels. Furthermore, the documentation deals with potable water, electric power and gas couplers, sewerage system, rainwater sewer and paved surface for pedestrians and motor vehicles. The thesis is elaborated as documentation for the building execution.
