Performance testing of networks with Mikrotik components
Kaláb, Vojtěch ; Kubánková, Anna (referee) ; Mašek, Pavel (advisor)
The goal of the thesis is to develop and describe application for Mikrotik Network stress testing. The aplication is developed in high-level scripting programming language Python. The aplication allowed us to configure and display in diagram our connected routers and network stress testing. Theoretical part is focused on Mikrotik company, their development and products. Next part is about theory of network stress testing and graph theory. The last part is about aplications development, programming language Python and used tools and libraries.

Programmable IR receiver
Géze, Daniel ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
The aim of this bachelor thesis is design and realization of solutions for hardware and software programmable IR receiver. IR receiver is actually a logic programmable automat, which responds to commands from the remote broadcast communications protocol RC6 designed by Philips. Codes of these commands can be assigned to different actions. Using the configuration application in PC by any code of buttons it is possible to order firmly programmed codes in a flexible management processor Cypress (CY8C29466). Configuration software for the PC has been created by using the python programming language. The main purpose of this device is helping for the handicapped people.

Analysis of geolocation databases
Zima, Štefan ; Červenka, Vladimír (referee) ; Komosný, Dan (advisor)
This thesis is focused on collecting data from commercial geolocation databases and its analysis. The theoretical part discusses techniques of IP geolocation, briefly describes commercial geolocation databases and mechanisms for accessing their geolocation services. The practical part of this thesis involves implementation of scripts for collecting and modification data retrieved from commercial geolocation databases for further analysis. First script collects the data and store them in output files in specified format. Second script modifies gathered data to achieve better accuracy. Detailed analysis is performed afterwards. Analysis is performed at several levels. This includes country, region and city accuracy as well as accuracy on latitude and longitude parameters. Output of this analysis will be conclusive, and will also display accuracy of tested geolocation services. The aim of this thesis is to analyze currently available commercial geolocation services and to prove their accuracy. Used scripts are implemented in Python programming language in version 3 using modules urllib, re and json. Scripts are test on commodity hardware with Linux operating system.

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.
