Life-Time Management of Process Devices in Industrial Practice
Lošák, Pavel ; Klemeš,, Jiří (referee) ; Ing. Zdeněk Jůza, Ph.D. MBA (referee) ; Vejvoda, Stanislav (advisor)
This dissertation examines life-time management of process and energetic devices in industrial practice, mainly in the area of steam power plants. Furthermore, it focuses on frequent damage mechanisms occurring in this area. It summarizes basics of damaging mechanisms occurring in the process industry area, their monitoring, evaluation and prediction. In the area of steam power plants, the main emphasize was placed on cumulative damage mechanisms. Within the dissertation, mechanisms of creep, fatigue, and their combinations were assessed. Major European standards were examined in order to discuss the amount of contained conservatism and their usability. Subsequently, attention was paid to the methods applicable for creep and fatigue combination evaluation. In the next step life-time monitoring and evaluation standard was discussed. The diagnostic software was created which includes creep, fatigue and creep-fatigue combination evaluation according to valid standards. For online life-time evaluation was proposed refined analytical solution for stress and strain calculation. To further extend the life-time management, the dissertation describes oxide scale damaging together with its evaluation and implementation into diagnostic software. The proposed software is extended by the material module which on the basis of defined materials allows easy and effective usage of material characteristics. For the purpose of refining life-time prediction accuracy, experimental device was schematically described. In addition, the device should be also able to verify used equations. Furthermore, the dissertation includes solution to industrially oriented cases. Firstly, a steam generator with damaged pipes was analyzed, afterwards damaged transferring pipeline. Further analyses deal with U-tube heat exchanger and its damaging. The causes of damage were discovered and corrective measures were proposed. The dissertation concludes with the summarization of potential activities for subsequent research in examined area.

Secure Transport of NetFlow and IPFIX Records
Štěpánek, Adam ; Grégr, Matěj (referee) ; Podermański, Tomáš (advisor)
This bachelor thesis deals with an IP flow based data network monitoring system. It presents the architecture of the NetFlow based monitoring, explains the basic terms, the NetFlow protocol and its alternatives. Further, weak spots of the monitoring systems are determined and a conceptual solution is proposed. This solution is implemented and described in detail. Finally, testing methods and results are discussed and the possibilities of further development and optimization are proposed.

A Tool for Automatic Generation of SQL Database Content for Software Testing
Minářová, Alice ; Charvát, Lukáš (referee) ; Smrčka, Aleš (advisor)
This thesis follows up a design and implementation of a set of two tools for testing data generating. The first tool analyzes PostgreSQL databse text output and creates a configuration file in a newly designed language that describes how the database content should be generated. Based on this file the second tool generates a SQL script to fill the target database. User can adjust the generated data to their own requirements by modifying the configuration file written in a domain-specific language. The language was designed to make possible adjustments quick and intuitive. The thesis also describes how this language should be handled. The two tools were tested on several artificially created databases and also on a real system database of Drupal. The tools are both operated via the command line which makes them suitable for usage in automation.

A Tool for Evaluation of Quality of Contribution to Open-Source Projects
Špigel, Radim ; Müller, Petr (referee) ; Smrčka, Aleš (advisor)
The aim of this work is an examination of contributions quality in development of open-source projects written in programming language Pytho. Detection of this quality is being probed by static analysis tools and hypotethical algorithm which is based on duration of curent contribution changlessness. In this work there is a basic description of revision control systems and distributed system Git. There is also a mention about basic software metrics and D3 library.

Dictionary for Mobile Devices with OS Android
Damborský, Tomáš ; Kouřil, Jan (referee) ; Smrž, Pavel (advisor)
This thesis deals with design and implementation of dictionary application for mobile device with an Android OS. The key feature of application is ability to perform fulltext search. This is achieved by using the SQLite database with Full Text Search extension. SQLite databases are generated from source lexical data in Lexical Markup Framework format.

Administration of DNS Servers for FreenetIS Project
Raška, David ; Janoušek, Vladimír (referee) ; Malčík, Dominik (advisor)
The goal of this bachelor's thesis is to introduce an alternative option of DNS servers management using graphical interface. In this thesis it is implemented a graphic user interface for DNS servers, zones and records management and connection of a DNS server to a network management system. ISC BIND 9 software is used as a DNS server and management interface is implemented to open-source project FreenetIS. Connection of both parts is made by a script, which continuously updates DNS configuration on a server.

Semantic Similarity of Articles
Veselovský, Martin ; Otrusina, Lubomír (referee) ; Kouřil, Jan (advisor)
This bachelor's thesis deals with modelling of structure of semantic relationships among articles in English language. There are introduced existing methods of articles representation and computation of similarity. The base method is vector space model, which represents document as vector of words. There are given weights of importance to these words using TF-IDF method. Next, there are described advanced methods of modelling, Latent semantic analysis (LSA) and Latent Dirichlet allocation (LDA). This thesis also deals with articles, which are semantically annotated, while weights of annotation words are computed by Stochastic Gradient Descent method. Evaluation of results takes place on the prepared test corpus of documents to which there is reference similarity evaluation.
