Validization of diagnostic methods in PTSD
Vágnerová, Anna ; Preiss, Marek (advisor) ; Heider, David (referee)
With this work, I became involved in an ongoing project of tool validation for measuring psychological trauma within the activities of the National Institute of Mental Health - Validation of tools for measuring psychological trauma. The aim of this thesis was to collect data from a clinical population with posttraumatic stress disorder (PTSD) and compare it with the results of diagnostic methods in the general population (N=303). The research clinical sample consisted of 31 respondents who, based on diagnostic criteria for PTSD diagnosis according to DSM-5, were divided into two research groups - with a probable PTSD diagnosis (N=17) and without a probable PTSD diagnosis (N=14). In this work, the results of three research groups were compared using the PTSD Checklist 5 method, which assesses the level of traumatization, and the Life Events Checklist-5 method, which examines the frequency of experienced traumatic events. At the same time, measurement of depressive and anxious symptoms of all participants was conducted to assess convergent validity. The results of statistical analysis showed that the PCL-5 method proved to be valid. The group with a probable PTSD diagnosis achieved statistically significantly higher values than the general population group, even in the results of methods measuring...

Test Planning Tool Extension for Distributed Systems
Mészáros, Filip ; Ráb, Jaroslav (referee) ; Ščuglík, František (advisor)
This bachelor thesis is about automatical software testing using the testing scheduler. It describes creation of the extension for the existing testing scheduler, so it will be possible to split effectively a group of tests to segments, that will be executed independently on each other. Tests are splitted according to the common characteristics of the enviroment, that need to be prepared for each test, and according to the dependencies between the tests. Furthermore, it describes what optimizations are used for splitting of the tests to subsets. Each subset of the tests runs on a standalone testing system, so the time needed for succesful completion of testing with the given set of tests is reduced. Created tool is succesfully used during everyday testing of the several products in the Acision company, to which was this tool made.

Determination of selected mycotoxins in tea
Pustka, Václav ; Maleček, Miroslav (referee) ; Kuchyňa, Jaroslav (advisor)
This diploma thesis deals with the development and validation of an analytical method using high performance liquid chromatography method with fluorescence detection for the simultaneous determination of aflatoxins and ochratoxin A in herbal and fruit tea. The theoretical part describes the most common groups of mycotoxins and the most important methods for their determination in food. The great attention is devoted to HPLC method and the overview of the derivatization techniques for aflatoxins B1 and G1 fluorescence response enhancement. The practical part of this study focuses on the optimization of sample extraction and purification, the settings of the instrumental analysis and the photochemical reactor assembly. The thesis also involves the determination of the basic performance characteristics for the successful method validation.

Front Wing for Formula Student
Vrubel, Vít ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
This work deals with the verification of the design of the front wing on the Formula Student car. The work is divided into three parts. In the first, a search of the wings used in the Formula Student competition is performed. The second part is devoted to the experiment and the last part is devoted to CFD calculations and comparisons with measured values. Computations were done on computational resources supplied by the project „e-Infrastruktura CZ“ (e-INFRA LM2018140) provided within the program Projects of Large Research, Development and Innovations Infrastructures. Computational resources were provided by the ELIXIR-CZ project (LM2015047), part of the international ELIXIR infrastructure.

Online DNSSEC Records Validation
Bachtík, Martin ; Čejka, Rudolf (referee) ; Lampa, Petr (advisor)
Master's Thesis is studying an extension that secures the domain name system by introducing the verifiability of authenticity of data, known as DNSSEC. Productive output is proposal of application and its subsequent implementation that at each stage of browse the namespace to the selected domain name checks the appropriatenesses of this extension and in detail reports the trusted chain.

Generator of Analysers of Documents Defined by RELAX NG
Šimonek, Jan ; Janoušek, Vladimír (referee) ; Martinek, David (advisor)
This bachelor's thesis deals with automatization of XML loading. This is accomplished by a generator of XML analyser. The generator (translator) takes a XML scheme in RELAX NG and it produces analyser in C++. The generated analyser is capable of unmarshalling and validating data from XML, providing access to the data and marshalling the data back to XML. Usability of this process is demonstrated on examples. Theory of the XML, XML schema languages and validation is also discussed.

Automatic Testing of Software
Mrázik, Matej ; Tisovčík, Peter (referee) ; Korček, Pavol (advisor)
The main goal of the bachelor thesis is to automate the testing of IQRF Gateway Daemon software. The practical output is a tool capable of testing the IQRF Gateway Daemon through an emulated virtual network of intelligent devices. In the theoretical part, the work outlines the issues of software testing to the reader. These principles are then applied in testing the IQRF GW Daemon. The reader will get acquainted with the resulting tool and its functionality, which will be able to further expand if necessary.
