Digital Image Steganography
Kolarčík, Tomáš ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This bachelor thesis deals with digital image steganography and implements some of the available methods. This thesis describes steganography on a general level, it's history and it's current form. It also shows it's classification according to the type of carrier, the classification of the methods according to the style of hiding data and the influence of the hidden information. The primary subject of this thesis is image steganography, where facts that allow imperceptibly hide data inside image are described. A great part of this thesis is dedicated to the characteristics of the methods, which we observe and to the methods themselves. All of the methods described are implemented in a graphical and console application. The created application provides multiple image formats for hiding. In the last part, testing is performed in terms of capacity, imperceptibility and robustness.

Performance Testing of Linux Kernel Scheduler
Vozár, Jiří ; Rogalewicz, Adam (referee) ; Malík, Viktor (advisor)
Výkon plánovače procesů v jádře operačního systému značně ovlivňuje rychlost a odezvu všech aplikací, které na něm běží. Jakýkoli propad výkonu pak může mít kritické důsledky na běhu aplikací. S příchodem každé nové technologie (např. symetrický multiprocesing) se kód plánovače vyvíjí a rozšiřuje. Proto jsou potřeba regresní testy nejen na jeho fukčnost, ale i výkon. Tato práce mapuje metody testování plánovače operačního systému Linux ve firmě Red Hat. Popisuje způsoby měření výkonu plánovače, sbírání informací o jeho chování, ukládání sesbíraných dat a jejich vizualizaci. Hlavním cílem práce je pak návrh a implementace nového způsobu vizualizace dlouhodobých měření a využití strojového učení pro automatické rozpoznání degradace výkonu mezi dvěma výsledky.

Testing Framework for Automatic Tests of MCUXpresso Config Tools
Dubovský, Tomáš ; Strnadel, Josef (referee) ; Crha, Adam (advisor)
The aim of this thesis was to analyze the existing solution of the MCUXpresso Config Tools testing framework, to design and implement various optimization options that will lead to increased testing efficiency. Three ways of optimization have been designed and implemented based on profiling of the existing solution. The first is to unify the launch of external applications under the new module runner. The second is implementing concurrency in Python using multiprocessing, multithreading, and asyncio, then comparing each method and selecting the most appropriate one. The third is the implementation of support for chained entry of commands in commands line interface in MCUXpresso Config Tools.

HIL test stand for universal electronic control units
Zouhar, Štěpán ; Musil, Filip (referee) ; Brablc, Martin (advisor)
This diploma thesis is focused on testing of Electronic Control Units, especially functional testing in which hardware and software is verified and also Model in the Loop, Software in the Loop, Processor in the Loop and Hardware in the Loop testing methods. Within practical part of this thesis testing stand for functional test of the ECU was developed and manufactured. It is connected to PC via Input/Output card, testing is controlled by MATLAB script. Whole process of testing is automated from initial upload of testing firmware to tested ECU over all phases of test up to bootloader flashing. Hardware in the Loop test was also created, in which ECU works as controller and DC motor is simulated in real time with PC in MATLAB environment.

Development and evaluation of computer application for teaching and determination of natural species
PECHAR, Luboš
Available e-learning applications for teaching and recognition of natural species and testing the level of achieved knowledge were evaluated in this thesis. Problems and limits of these tools were identified. Based on the evaluation the unique tool for test developing was designed which can be used for self-learning as well as for testing within the school program. The outcome of the theses is a new application "Poznávačka". New application allows teachers to create lists of species which are available as a study material for their students.

Evaluation of motor abilities and basic somatometric indicators of children in the project ''Děti na Startu''
Benešová, Barbora ; Hájková, Jana (advisor) ; Svobodová, Irena (referee)
The aim of this thesis is to evaluate the level of motor abilities and to find out basic somatometric indicators of children in the project ''Děti na startu''. The theoretical part will be processed in the form of literary research, the practical part will describe and evaluate selected motor tests in relation to age and basic somatometric indicators. In total, five tests of motoric abilities and one assessment of somatometric indicator were evaluated and used in the practical part. The first test evaluated was a standing broad jump where the vast majority of children achieved a below-average score. The next test evaluated was sit-ups (60 sec), in this test the children achieved mostly average results. The third test was an endurance shuttle run, in which the most often evaluated result was significantly below average. The fourth test was a shuttle run of 4x10 meters, in this test more than half of the children came off average or better. The last exercise test was a modified standing forward bend test, with 22 children achieving normal and better values. The BMI values, that we calculated were between 14,3 and 18,5. Keywords: Evaluation, motorics, motor abilities, project "Děti na startu", somatometric indicators, unifittest, testing.

The impact of static and dynamic stretching on coordination and flexibility in children in primary school
Plachá, Tereza ; Kainová, Lucie (advisor) ; Jahodová, Gabriela (referee)
TITLE: The impact of static and dynamic stretching on coordination and flexibility in children in primary school AUTHOR: Tereza Plachá DEPARTMENT: Katedra tělesné výchovy SUPERVISOR: Mgr. Lucie Kainová ABSTRACT: In my final thesis I want to deal with two types of warm-up - static stretching and dynamic stretching. Warming up is an important part not only of the sport performance, but also at the beginning of the physical education lesson. In schools, this phase is often neglected. With the help of selected tests, I will observe primary school pupils at primary school to get better results after static or dynamic stretching. I will watch them in coordination and flexibility. I compiled two types of stretching, which I will try in grades 1, 3 and 5. In the first lesson, I will do static stretching with the pupils after the proper warm-up. In the second lesson, I will include dynamic stretching along the busy part. In the main part of the lesson, the pupils then pass three tests for coordination - flamingo, crossing the bench and running with the roll; and three for flexibility - standing forward bend, shoulder joint range, and hip joint range. After dynamic stretching, the children are warmed up, reaching the necessary temperature for further activities. They have a greater range of motion and therefore...

Motor abilities of younger school age children in floorball
Dubová, Kristýna ; Hájková, Jana (advisor) ; Pádivý, Martin (referee)
The target of my thesis is to find out the level of physical abilities of younger school boys who are active in floorball. I tested the level of motor abilities using the Unifittest (6-60) and the Holistic Motor Test. I did the testing in the floorball club called Start 98 Prague, where I tested 62 players. I compared the level of motor abilities with the general population. I also wanted to find out how big the differences will be with the players who are divided by performance. The research section shows that the players have achieved the best results in their strengths tests. Furthermore, it turned out that the worst achievements were obtained by the players in agility tests. Average results were obtained by the players during their speed skills tests. KEYWORDS younger school, age, motor abilities, floorball, testing, motor abilities tests
