Free Software and Cooperation as a Course for Development of Czech Librarianship
Jansa, Václav ; Nič, Miloslav (advisor) ; Dvořák, Jan (referee) ; Sklenák, Vilém (referee)
The dissertation focuses on the use of free software in Czech libraries. Both real practice and librarians' attitudes to this type of software are analyzed. The main goal of the dissertation has been to evaluate the attitudes of Czech libraries to free software, to analyze its use in practice, to design information and communications strategy for free software project and to implement it using Evergreen as an example project. In order to achieve the goals, both qualitative and quantitative research methods have been used. These included a survey, web data gathering and analysis and also case studies. The devised and implemented information and communications strategy consists of eight main parts (setting up a local community, creating communication tools, organizing seminars, Czech localization, the creation of first common catalogues, making documentation publicly available, active involvement in the international community and establishing a legal entity to improve awareness about free software among librarians) which are complemented with a SWOT analysis evaluating the strategy implementation.

Evolutionary Design of Boolean Functions for Cryptography
Dvořák, Jan ; Vašíček, Zdeněk (referee) ; Husa, Jakub (advisor)
The goal of this bachelor's thesis is to compare various selection methods used in cartesian genetic programming applied to a problem of various types of cryptographically significant boolean functions. I focused on these selection methods: evolutionary strategies (1+lambda) and (1,lambda), tournament selection and roulette selection. The chosen problem was solved by an implementation of CGP with the above-mentioned selection methods and by a statistical evaluation of data acquired from conducted experiments. Evaluation of mentioned data has shown that the best results in case of bent functions were achieved while using (1+lambda) evolutionary strategy. The roulette selection performed the best in case of balanced functions with high nonlinearity.

Aerial platform for flight time measurements
Schneider, Tibor ; Dvořák, Jan (referee) ; Pokorný, Jiří (advisor)
The bachelor thesis elaborates on creating a mathematical model and realisation of a flying platform. Consequently, it compares results from the mathematical model which simulates flight duration with results which were measured with constructed flying platform. In the first part of the thesis, flying platforms are introduced and also the usability range and what types exist. Matlab was chosen as a language to create the script. In the second part, principle of the matematical model is explained, graphs which explain power influence in UAV movement are presented. There are time dependences of hovering time on different UAV weight, flight distance or outside environment temperature. In the end, there is final comparison of theoretical calculations with measured time values. According to the calculations and measurments, it is more optimal to fly with a speed of 4m/s rather than 1m/s. According to the calculations, distance of 1000m was on the limit, therefore, the measurments were conducted within the range of 600m.
