LOD for GPUEngine
Staněk, Jan ; Milet, Tomáš (referee) ; Starka, Tomáš (advisor)
The representation of 3D polygonal model on several levels of available detail is a problem inherent in the process of rendering a scene. Highly-detailed models, if placed far from the camera, suffer from spatial aliasing that results from inadequate sampling of their surface, and require disproportionately large amount of time to render. Low-detailed models on the other hand reduce the visual quality of the scene when placed too near to the camera. This report delves in both the theory and the practical techniques used for solving these problems. It describes various published solutions and the principles behind them, and presents a design and an implementation of selected techniques for the GPUEngine library.

Study of chemical cleaning of surfaces by LEIS method
Staněk, Jan ; Polčák, Josef (referee) ; Bábor, Petr (advisor)
This thesis deal with studying chemical etched surfaces of cadmium telluride crystals (CdTe crystals) by low-energy ion scattering spectroscopy (LEIS method). In the theoretical part, there is description of physical essence of LEIS method, including experimental arrangement of Qtac100 instrument, on which the experiment is measured. The LEIS method is also compared with X-ray photoelectron spectroscopy (XPS). There is summary of properties and structure of CdTe crystals including principle of X-ray detectors, which are the primary use of the crystals. In experimental part there is a description of measuring process, starting with a calibration measurement, ongoing with a chemical etching and ending with a surface analysis. There are examples of LEIS spectra with comments and interpretation including comparison with XPS data.

DoS a DDoS útoky na SIP protokol
Staněk, Jan ; Peterka, Jiří (advisor) ; Vozňák, Miroslav (referee)
The aim of this diploma thesis is to get accustomed with the SIP protocol and with the problematics of attacks targeting this protocol, with the emphasis on DoS and DDoS attacks. The thesis focuses on detailed classification of the attacks, possibilities and forms of generation of the attacks and methodics of defense against them. The attacks of the flood type are especially stressed because they are easily generated and the SIP components are very prone to these attacks. Prototype implementations of the most important ideas concerning attack generation and protection against these attacks are also part of this thesis. Practical tests of the implementations performed in a simulated SIP environment are also included. 1

Analysis of Pardubice micro-region's transport service
Staněk, Jan ; Marada, Miroslav (advisor) ; Květoň, Viktor (referee)
Diploma thesis provides a comprehensive viewpoint at transport services in the Pardubice region, both in terms of public transport supply and demand from people at it. One of the key objectives of this work is to find the influence of characteristics on the selection of mode of transport used by the people to get to work and school at the municipal level. In addition to analysis based on secondary data there is a part of this thesis, which evaluates questionnaire study, particularly in relation to the previous analysis. This comparison of two views, first based on objective statistics data and second based on the subjective view of the reference population of the region, is one of the main values of this study.

Pattern recognition by moments method
Staněk, Jan ; Pangrác, Ondřej (referee) ; Bálek, Martin (advisor)
This bachelor thesis and computer program are focused on the moments method which is used in pattern recognition. The text contains basic information about the method, its advantages, constraints, modifications, and extensions. The thesis focuses mainly on the last step in the process of pattern recognition which is the computation of the moments of an image and construction of a decision tree based on a known set of patterns. The accent is put on the variability of the construction of a decision tree and on the subsequent analysis and comparison of results gained by different settings of process conditions. Program is created in Java programming language.

Danish TV System
Staněk, Jan ; KALLISTA, Jaromír (advisor) ; Badač, Peter (referee)
The author of this thesis is dealing with danish TV system. He is focusing on it´s historical developement, structure, regulation, way of financing and on it´s most important players. He analyses the literature works of danish professional authors and primary sources, like websites and presentations of included institutions. The author creates current and broad picture of danish TV in 2016, of it´s mechanisms and elements. Then, he compares his findings with system of czech TV´s, which may seem same functional as danish from an external point of view , but it´s nation and international succeeds are imcomparable.

Software Tool for Investment Project Evaluation
Pokorný, Michal ; Staněk, Jan (referee) ; Režňáková, Mária (advisor)
This bachelor thesis engages in design and creation of software tool for supporting decision making in comparison of success between potential investment projects. The tool is capable of evaluating recovery of investment by using The Net present value method and Internal rate of return. The risk exposure is taken into account by the Modified net present value and modeling by Monte Carlo method implemented using Microsoft Visual Basic for Application.
