Realistic Model of the Sky
Kussior, Zdeněk ; Bílek, Václav (referee) ; Drahanský, Martin (advisor)
The paper describes a theoretical base and realization of realistic volumetric clouds visualization in an environment of real-time simulator. The first part is concerned with a meteorological background of this problem. I show international classification of ten basic cloud types including a short description and cases of occurence. The following part is concerned with an interaction between cloudiness and simulation core, which is based on the fact, that each cloud acts as a mechanical or an electromagnetic obstacle. This should be considered on some way in simulation. The next part describes technologies and practical implementations of visualization and evaluates their characteristics. Finally, the last chapter describes my implementation and tries to outline project advancement.

Complex design of the overhead line section of the transmission system
Reiskup, Filip ; Valiga, Matěj (referee) ; Ptáček, Michal (advisor)
The aim of thesis is a design of overhead lines of transmission system under specific weather conditions in given area. Furthermore, it gives a summary about the transmission and distribution systems and describes basics of overhead lines, used conductors and pylons in Czech Republic. It also presents the issue of climate conditions having a eminent influence on overhead lines. Moreover, theoretical part of thesis contains conductor mechanics and also mentions asymmetric state of overhead lines. Practical part deals with a design of specific part of overhead lines at voltage level of 400 kV and generally evaluates area where lines would be operated. In this area the new power energy source is hypothetically planned and therefore thesis analyzes possible variants of connection this source to transmission system. For one of these variants there are the calculations of two sections of the overhead lines under different weather conditions in more detail. The results bring longitudinal profile and assembling table for each section and they demonstrate the major impact of icing on the overhead lines.

Steel Structure of Observation Tower
Virág, Patrik ; Pilgr, Milan (referee) ; Hron, Lukáš (advisor)
The subject of the diploma thesis is design and structural analysis of loadbearing steel structure of observation tower, which is located southeast of Černá Hora, township Blansko. The design is processed in two options. Parts of the thesis are engineering report, structural design report for both of the options and graphical documentation in specified range. The structure’s height is 25.3 m and maximal ground plan dimension is 6 x 6 m. Steel grade S355 was chosen as main material. The sub-objectives of the structural analysis are load effects calculations (permanent load, imposed load and climatic load), entering of loads to the calculation model and calculation of internal forces and deformations. An assessment of the supporting elements and selected joints is also included. There are dynamic design features considered in the calculation. All calculations were performed in accordance with valid ČSN EN standards.

Aircraft de-icing systems
Smékal, Aleš ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
The bachelor´s thesis is familiarization of me with icing on aircrafts. It includes the distribution systems for anti-icing and de-icing, energy intensity and efficiency are also included. It contains icing situations, which are very dangerous for aircrafts. Thesis shows possibilities, how to prevent ice formation, detect icing and keep pilot informed. And finally remove ice.

Aircraft de-icing systems
Fazekaš, Slavomír ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
The aim of my bachelor thesis is to make the acquaintance of the danger of ice coating on airplanes, it s creation and the way of removing. The study involves the description of particular systems designed to protect airplanes against the ice coating and their dividing into deicing and anti-icing systems. The systems are divided by the exploited energy and by the place of installing. The emphasis is centred on the efficiency and the energy intensity of these systems. A part of my study also deals with the removing of ice coating arised on ground and with the description of basic parameters, which must be fulfilled by these systems according to the flying rules.
