Assessment of body composition and physical fitness using the ALPHA test battery
Husovská, Andrea ; Jandová, Soňa (advisor) ; Bunc, Václav (referee)
The present thesis deals with the influence of body composition on physical fitness. The thesis deals with the issue of increasing prevalence of obesity in children and adolescents. The aim of the thesis is to assess physical fitness in older school-aged children using a validated test battery and to determine the association of physical fitness in these children with their body composition. A total of 52 pupils aged 12-14 years were tested, of whom 34 were girls and 18 were boys. We used a modified Assessing levels of physical activity (ALPHA) test battery to determine the physical fitness of the children and adolescents. We also used a questionnaire survey to determine anthropometric parameters relevant to body composition. For the actual measurement, we used three skinfold measurements, dynamometry, Unifittest (6-60). F-test was used to calculate statistical significance of differences and Cohen's d was calculated to calculate substantive significance. The results showed that girls had higher amount of subcutaneous fat than boys. There was no difference in body weight and body height between girls and boys. Compared to boys, girls had a lower mean time spent in physical activity outside physical education. In conclusion, body composition has a great influence on physical fitness in older...

Influence of athletics training on physical ability of 13 years old pupils
Holcová, Tereza ; Kašpar, Ladislav (advisor) ; Teplý, Lukáš (referee)
The aim of the practical part of this baccalaureat thesis is to find out, if athletic training has and impact on physical ability of athletes at the age of 13, in comparison with the standards set by the Manual for manual and computerized assessment of basic motor performance and selected characteristics of the body structure of youth and adults in the Czech Republic, but also towards pupils who are attending other sport events or do no not play any sports at all. The UNIFITTEST test batery was used. It tests children in foru disciplines. The collected data were tabulated and then evaluated based on the above objectives. The theoretical part is devoted to the characteristics of physical fitness and ist components. It also touches on body composition, obesity and underweight. It characterizes the older school age and brings us closer to the athletics training of this age group.

Network interface card performance testing
Karabelly, Jozef ; Nagy, Peter (referee) ; Grégr, Matěj (advisor)
Táto práca sa zaoberá významom testovania výkonnosti sieťových kariet (NIC) v inžinierstve sietí, najmä pre systémy používajúce moderné jadro Linuxu, v dôsledku rastúcej priepustnosti sietí a expanzie viacjadrových procesorov. Vyvíja škálovateľné a prispôsobiteľné testovacie scenáre pre testovanie NIC, ktoré zohľadňujú zložitosť rýchlo sa vyvíjajúceho hardvéru a softvéru a smerujú k stabilným, reprodukovateľným výsledkom v rôznych scenároch. Výskum zahŕňa analýzu akcelerácie sieťových mechanizmov jadra Linuxu, použitie nástrojov kontinuálnej integrácie pri objemnom testovaní a dôkladné preskúmanie hardvérových konfigurácií. Účinnosť testovacích scenárov je validovaná rozsiahlým testovaním na presne definovanom testovacom prostredí, čo zlepšuje pochopenie a optimalizáciu výkonnosti NIC v komplexných sieťových systémoch založených na Linuxe.

Practical Aspects of Reducing Technical Debt in Software Products
Hricovová, Alžbeta ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This thesis focuses on practical aspects of reducing technical debt in software products, focusing on testing, refactoring, and continuous integration. Technical debt arises from compromises made during software development and, if unaddressed, can negatively impact the product and the company developing it. One of the solutions to reduce technical debt is continuous refactoring and code maintenance. This work describes identified violations of good object-oriented programming principles in the selected product and procedures applied to the product to mitigate the impact of its technical debt.

Performance Comparison of Libraries for Homomorphic Cryptography
Babjak, Pavol ; Perešíni, Martin (referee) ; Malinka, Kamil (advisor)
Kryptografia je neoddeliteľnou súčasťou oblasti počítačovej bezpečnosti. Pri využívaní bežných kryptografických metód a operáciách nad nimi však nie sú jednotlivé dáta nijako chránené proti neoprávnenému prístupu alebo krádeži tretími stranami. Homomorfná kryp- tografia rieši presne daný problém, teda dokáže pracovať s dátami, ktorých obsah nepozná a súčasne dokáže vykonávať jednotlivé operácie nad nimi. Cieľom práce je nájsť jednoduché prípady užitia pre praktické využitie homomorfnej kryptografie, implementovať ich pomo- cou jednotlivých prostredí ktoré pre svoje fungovanie využívajú túto technológiu a zmerať ich výkonnosť a ďalšie dôležité aspekty pri výbere najvýhodnejšieho prostredia a šifrovacej schémy pre danú praktickú aplikáciu.

Generate ICMPv6 and IPv6 packets for load testing using JMeter tool
Šulka, Samuel ; Člupek, Vlastimil (referee) ; Dvořák, Jan (advisor)
The Bachelor Thesis deals with flood attacks using generating of ICMPv6 packets in an environment without IPv4 protocol. A Trafgen configuration file was created, which had the task of sending ICMPv6 packets. For other attacks was used Scapy in Python. A plug-in modul for software Apache JMeter was created for each scenario. Scenarios were tested on real device and the results were documented in write and visual form.

Comparator of Test Results
Čerbák, Patrik ; Kozák, David (referee) ; Smrčka, Aleš (advisor)
Tato bakalářská práce se zaobírá tématem testování OpenJDK ve firmě Red Hat a jak toto testování zefektivnit. Jeden z hlavních problémů při testování je porovnání, zda určitý test spadl pouze na jedné variantě testovací sady nebo na více variantách (jedna testovací sada se stejnými testy má mnoho variant – liší se například v operačních systémech, běhové architektuře, atd.). Kvůli tomuto je v této práci navrhnut a implementován nástroj pro porovnávání výsledků testů právě na odlišných varintách jedné testovací sady. Tento nástroj je implementován v programovacím jazyce Java a může běžet samostatně jako CLI program nebo ve speciálním webovém prostředí. Tento komparátor je zároveň součástí takzvaného Jtreg pluginu, což je open source rozšíření do nástroje Jenkins, které se používá v OpenJDK QA týmu firmy Red Hat. Samotný nástroj umožňuje spoustu věcí, například filtrování testovacích sad pro porovnání, vytvoření porovnávací tabulky spadlých testů, tabulky s podobností stack trace spadlých testů nebo třeba tabulky porovnávající výsledek sestavení jednotlivých testovacích sad.

Testing of aeration elements
Špunarová, Kateřina ; Úterský, Michal (referee) ; Hluštík, Petr (advisor)
In the bachelor thesis entitled testing of aeration elements, research is carried out on aeration systems and aeration elements used at wastewater treatment plants. The practical part describes the methodology of measurement and evaluation of data from the testing of specific aeration elements. The aim of the work is the comparison of certain parameters such as oxygenation capacity, opening pressures and energy consumption. These parameters can have a significant impact on the efficiency and operating costs of wastewater treatment plants.

A Tool for Generating Test Paths Based on a Given Criterion
Bíl, Jan ; Rogalewicz, Adam (referee) ; Smrčka, Aleš (advisor)
The automatic generation of test inputs according to a specified coverage criterion has the potential to significantly reduce costs in the development of critical applications. This work focuses on designing and implementing a tool that systematically generates paths in the control flow graph generated from function of such application, that meet the specified coverage criterion targets. These paths are then transformed into the corresponding SMT (Satisfiability Modulo Theories) format, and their feasibility is verified using the Z3 SMT solver. For paths that are feasible, a set of input valuations for which the formula holds is simultaneously generated. This collection of valuations formes a set of test inputs that effectively meet the desired coverage criterion. Final test inputs are tested function parameters and state of global parameters.
