Using repeaters to enhance cellular communication signals
Kubásek, Ondřej ; Kubánek, David (referee) ; Koutný, Martin (advisor)
This thesis examines possibile applications of RF repeaters to improve the mobile networks signal coverage. An overview of various types of repeaters is given, while advantages and disadvantages of particular types are discussed. The questions of antenna isolation and resulting repeater gain settings are solved here as well. The thesis also considers a proposal of repeater system to improve the signal coverage in the trains of the České dráhy, a.s. company. This proposal analyses the questions of signal penetration and propagation in trains, possibilities of implementing repeaters into carriages, system diagnostics and the financial issues. The proposal is supported by the results of a trial measurement taken out in the cooperation among T-Mobile Czech Republic a.s., Vodafone Czech Republic a.s., Telefónica O2 Czech Republic a.s., České dráhy a.s. (Czech Railways Company) a ČD-Telematika a.s. on the Prague – Ostrava line.

CNV detection in the sequencing data
Pleskačová, Barbora ; Škutková, Helena (referee) ; Jugas, Robin (advisor)
Copy number variation detection in prokaryotic organisms is currently receiving more and more attention, mainly due to the association of CNV with pathogenicity and antibiotic resistance in bacteria. The algorithm designed in this thesis uses peak detection in sequencing coverage to detect CNV segments. Read coverage is commonly obtained by mapping sequencing reads of one individual to an already known reference of another individual of the same species. However, two individuals will always differ in a certain number of genes, resulting in unmapped reads that are unnecessarily discarded. Therefore, this work assumes that the biological accuracy of CNV detection can be increased by using a new reference that is created from the same set of reads as the reads mapped to this reference. Sequencing reads of Klebsiella pneumoniae individuals are used to verify this assertion.

Applications Based on Generator of Test Cases
Leonteva, Valeriia ; Bardonek, Petr (referee) ; Strnadel, Josef (advisor)
The aim of this bachelor's thesis is to create an overview of the current state of tools that allow automatic generation of test cases and select one tool to show how it works and its ability to generate executable tests. The UPPAAL program was chosen for the following work. Tool allows to create a model of the selected system using timed automata, verify and simulate its operation and create a test case for the system. In the results, the tool generates a path through the system, which can be saved in the form of executable test cases in any programming language. Three different systems were chosen for testing: a light switch system implemented in Java; 2-bit multiplier, which behavior is described by Verilog language; and a simplified elevator system, which working process is introduced in C language. As a result, executable test cases were obtained for selected systems along with their features such as system coverage, number of steps to achieve goals, and quality of generated paths.

Software for cameras configuration design of the panoramic system
Jílek, Michal ; Grenar, David (referee) ; Kříž, Petr (advisor)
This work deals with software design in C ++ language and with graphical output using OpenGL for scanning tribune lenses of cameras with different parameters so that the user lens configurations are known beforehand in order to create panoramic coverage of the stadium stadium. The principle of image capture, lens parameters, and formulas for calculating their appropriate layout on the stadium to collect a panoramic image together is discussed. These are: focal length, viewing angles, coverage calculations, image resolution. Furthermore, a draft program implementing the issue.

Tiling problems in combinatorics
Dvořáková, Tereza ; Slavík, Antonín (advisor) ; Halas, Zdeněk (referee)
The thesis represents a collection of solved problems concerned with covering planar shapes (mostly rectangles with integer sides) by tiles known as polyominoes (e.g., domi- noes, trominoes, tetrominoes, etc.). In most cases, the goal is to find a tiling or to prove that no such tiling exists. In more difficult problems, the task is to deduce conditions for the rectangle to be tileable by specified polyominoes. The last chapter is devoted to calcu- lating the number of all possible tilings of the specified rectangle.
