Scripts for automated editing of fonts in PDF files
Gmitter, Jakub ; Zeman, Kryštof (referee) ; Hanák, Pavel (advisor)
Master's thesis deals with the issue of font encoding in PDF documents. Proper font encoding is necessary for searching and copying text from such documents. Thesis includes a description of the internal structure of PDF documents, page representation, font types and their encoding, and important objects needed for proper font representation. Understanding of these areas was necessary for development of scripts that are able to repair incorrect font encoding. Two Python scripts were developed as part of the thesis. The first one verifies the integrity of repaired PDF files using SHA-256 hashes computed from their contents. The second script repairs corrupted font encodings in the documents. The necessary information for the functionality of both scripts has been stored in the corresponding JSON structures. The repair script targets PostScipt fonts of type 1. Core function of the repair script is the generation of a ToUnicode object that correctly maps glyphs to Unicode codes within the font. The script has been tested on approximately 200 electronic issues of a Czech magazine that have been provided as sample data. From these sample files, only those that had completely corrupted font encodings were chosen for further work. Other sample magazines only had corrupt encoding of characters with diacritical marks. These magazines were analyzed, but the script is unable to repair them. Commented Python source code, compiled Windows executables and a user guide are available in the electronic attachment and in the author's GitHub repository.

Analysis and Aggregation of Czech Parliament Data
Talašová, Irena ; Burget, Radek (referee) ; Očenášek, Pavel (advisor)
The aim of this work is to create a variety of statistics and reports on the functioning of Parliament of Czech Republic. Data for these statistics are gathered from the pages of the Czech Parliament and stored in to a database. Results are presented mainly in the form of tables, graphs and other methods on a publicly accessible Web site. Results should be as clear as possible, comprehensible and provide interesting and unusual information.

Management of Exhibition Sites for a Festival
Duchoň, Radek ; Klobučníková, Dominika (referee) ; Křivka, Zbyněk (advisor)
The aim of this work is to create a new information system for the management of exhibition spaces at the festival called Animefest. The web application is implemented in Python using the Django application framework. The system uses a vector map in SVG format for the definition and representation of spaces. The created solution also provides its own system for recording the history of changes in the database. The system will allow festival organizers to catalog spaces and preserve the history of cooperation with various partners.

System for Automatic Calibration of a Robotic Tool
Šála, David ; Chromý, Adam (referee) ; Žalud, Luděk (advisor)
This Master's thesis describes the design and implementation of an experimental sample for automatic calibration of a robotic tool using machine vision methods under the auspices of the company SANEZOO EUROPE s.r.o. It deals with the analysis of all used methods of performing TCP calibration, on the basis of which it is implemented. The application is based on the Point-counterpoint method, where the robot is guided against the calibration point from three different directions, all perpendicular to each other. The calibration point is set using the ArUco marker. In order to detect the endpoint are used images from two cameras that are at the right angles to each other. Using conventional computer vision methods and an HSV filter, the endpoint of the instrument is found in the images and is guided to the calibration point. From the obtained coordinates, the searched endpoint of the robotic tool in the robot coordinates is found using the optimization method Particle Swarm Optimization. This application, therefore, performs TCP calibration in a fast time, thus reducing production downtime almost without human intervention.

Detectors of Structured Data for Generating Test Data
Znojil, Ondřej ; Turoňová, Lenka (referee) ; Smrčka, Aleš (advisor)
This works is focused on design and implementation of utility for analysis of structured data of often used formats as JSON or XML. Utility is one of many components of Testos platform, which is set of testing utilities, communicating with each other. Primary goal of this thesis is creation of analysator for the prupose of testing. Utility is used to aggregate input data, determine occurence of each data entity and abstraction of its scalar values.

Using of Data Mining Method for Analysis of Social Networks
Novosad, Andrej ; Očenášek, Pavel (referee) ; Bartík, Vladimír (advisor)
Thesis discusses data mining the social media. It gives an introduction about the topic of data mining and possible mining methods. Thesis also explores social media and social networks, what are they able to offer and what problems do they bring. Three different APIs of three social networking sites are examined with their opportunities they provide for data mining. Techniques of text mining and document classification are explored. An implementation of a web application that mines data from social site Twitter using the algorithm SVM is being described. Implemented application is classifying tweets based on their text where classes represent tweets' continents of origin. Several experiments executed both in RapidMiner software and in implemented web application are then proposed and their results examined.

A Tool for Robustness Testing of Web-Services
Zelinka, Tomáš ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This project deals with testing of web services. The result of this work will be a tool for load testing of web services using fault injection in their communication. The first part of the project discusses the basic aspects of testing web services. The second part of the work is more focused on testing high loads in combination with fault injection. The tool will allow automated run of the tests. The distributed model of the tool was designed to simulate real loads. In the last chapter are summarized achieved results.
