Adaptive formations for virtual agents
Švagerka, Michal ; Plch, Tomáš (advisor) ; Čermák, Miroslav (referee)
There is a growing number of virtual agents in today's virtual worlds. This is directly related to the need of coordinating their behavior and movement. In this work we design algorithms to maintain desired formation of agents while moving through difficult terrain. The methods we study should maintain the requirements of the formation as well as traverse along various obstacles. We then use an arbitrary fitness function to compare the performance of these methods on typical scenarios.

The European Commission as an actor during the crises solutions
Čermák, Miroslav ; Kasáková, Zuzana (advisor) ; Šlosarčík, Ivo (referee)
More than ten years after the largest economic crisis, which stroke the European Union in 2008 and thoroughly tested its readiness and ability to act, Europe was hit by a global pandemic of COVID-19. Because of this crisis, the European Union and its institutions faced a number of challenges, stemming from unprecedented measures imposed to tackle it. In contrast with the economic crisis, it was not only the European industrial and financial sectors but also more segments, essential to the functioning of the European Union itself, which were affected by the recent crisis. The aim of this thesis is to point out the differences of impacts of the two crisis and to find out the role played by the European Commission during the process of dealing with them.

SPARQL compiler for Bobox
Čermák, Miroslav
The goal of the work is to design and implement a SPARQL compiler for the Bobox system. In addition to lexical and syntactic analysis corresponding to W3C standard for SPARQL language, it performs semantic analysis and optimization of queries. Compiler will constuct an appropriate model for execution in Bobox, that depends on the physical database schema.

Analysis of the 2014 European Parliamentary election in Great Britain
Čermák, Miroslav ; Kasáková, Zuzana (advisor) ; Váška, Jan (referee)
Bachelor thesis Analysis of European Parliament Elections 2014 focuses on topic of the theory of second-order elections which is put into context of the United Kingdom's political system. At first the theory of second-order elections is introduced for using on the examples of British politics. Thesis tries to answer the question whether the European Parliament Elections 2014 could be find as a second-order elections. Text analyzes turnout and results of single british political parties in past European Parliament Elections and compares these statistics to results of European Parliament Elections 2009 and General Elections 2010. Thesis works with three component research criteria which analyzes single hypotheses in way of theory of second- order elections. The results of every single criterion that tend to be used correctly. So thesis leads to conclusion that the European Parliament Elections 2014 could be find as a second order elections.

Simulation of Multi-UAV Cooperative Surveillance Using Pogamut and USARSim
Dufek, Jan ; Plch, Tomáš (advisor) ; Čermák, Miroslav (referee)
The main objective of this thesis is to introduce a simulation platform, which has been developed utilizing Pogamut and USARSim, for cooperative aerial surveillance using multiple unmanned aerial vehicles (UAVs). The graphical user interface (GUI) of the simulator contains the automatically created bird's eye view of a 3D virtual environment. This is used to enter locations and parameters of objects (UAVs, charging stations and areas) and also to visualize the process of a simulation. The thesis proposes a system for the analysis of the quality of surveillance, whose results are presented in the GUI in the form of a time graph and a heat map. Part of the proposed platform is a UAV objective-based control system including charging stations scheduling. A total of seven algorithms for cooperative surveillance has been implemented, tested in three different scenarios and analyzed for coverage quality. Powered by TCPDF (www.tcpdf.org)

Model-driven Pretty Printer for Xtext Framework
Novotný, Marek ; Malohlava, Michal (advisor) ; Čermák, Miroslav (referee)
The domain-specific language allows for describing problems of a concrete domain, for which the language is created. This fact implies that a number of languages of this kind grows with a number of problem domains. The use of domain-specific languages brings a necessity to pretty-print these languages, where the concept of pretty-printing consists of code formatting and syntax highlighting. One of tools that allow for creating domain-specific languages is the Xtext framework, which offers only a limited range of tools that are able to define a configuration for pretty-printing. Moreover, these tools are hardly understandable because they are confusing and requires knowledge of Xtext's internals. Thus this thesis introduces a new way of pretty-printing domain-specific languages. The way is based on declarative definition of formatting rules. Furthermore, this thesis helps a user to create formatting rules by utilizing nontrivial heuristics.

Web server attack analyzer
Mižišin, Michal ; Novotný, Miroslav (advisor) ; Čermák, Miroslav (referee)
Web server attack analyzer - Abstract The goal of this work was to create prototype of analyzer of injection flaws attacks on web server. Proposed solution combines capabilities of web application firewall and web server log analyzer. Analysis is based on configurable signatures defined by regular expressions. This paper begins with summary of web attacks, followed by detection techniques analysis on web servers, description and justification of selected implementation. In the end are characterized possibilities of further development in area of better results of false positives. Implemented detection of all proposed attacks did slow down server response time by 10% and was able to detect more than 99% SQL injection, Path traversal and SSI injection attacks contained in web application security scanners.

Voice Communication System
Stránský, Martin ; Ježek, Pavel (advisor) ; Čermák, Miroslav (referee)
This text is aimed at solving problems that are associated with communication over IP networks, problems that are primarily related to real-time voice communication. Outcome of this thesis is program with voice communication as main feature. Other features include administration of communications using given permissions system. This application allows multiple concurrent separate communications of two or more participants, while ensuring correct functionality over unreliable protocol. Program can be extended using third party plug-ins without any modifications to the program itself. Application is targeted at Windows operation system with .NET installed.
