Effect of volcanic ash to Air Transport
Soukop, Robin ; Šplíchal, Miroslav (referee) ; Chlebek, Jiří (advisor)
This master's thesis deals with the issue of volcanic ash as a complex and its impact on aviation, including the volcanic activity itself (conditions for its existence, for existence of eruptions and their basic products). In addition, the thesis also deals with effect of volcanic ash on aircraft and airports, possibilities of its detection or monitoring as well as mechanism of its spreading in airspace. The emphasis is laid mainly on air incidents related to volcanic ash and on danger it poses to the airspace of the Czech Republic.

Composite electrode materials for lithium-ion batteries based on LiFePO4 prepared using GAC method
Vilhelm, Ondřej ; Neoral, Jiří (referee) ; Čech, Ondřej (advisor)
Presented work investigates the problem of secondary lithium-ion cells and the different available cathode materials. We have prepared samples of LiFePO4 with the addition of different kinds of carbon materials such as Super P, Vulcan and expanded graphite. We have always created the sample with and without surfactant. Developed samples were compared by measuring electrochemical methods (cyclic voltammetry, charge and discharge cycles and impedance spectroscopy). We also modeled the three-point cell for measuring electrochemical electrode materials.

Easy Vulkan
Halás, Timotej ; Chlubna, Tomáš (referee) ; Milet, Tomáš (advisor)
Zatiaľ čo staršie grafické API (Application Programming Interface) ako OpenGL alebo DirectX verzie 11 a nižšej sa v súčasnosti stále bežne používajú, novšie rozhrania API, najmä DirectX 12 a Vulkan, prinášajú mnohé vylepšenia, ako je lepší výkon, natívny Ray-tracing na podporovanom hardvéri a efektívnejšie využitie CPU a GPU. Vylepšenia výkonu a efektívnosti sú výsledkom povahy rozhraní DirectX 12 a Vulkan API. Obidve sú pomerne nízkoúrovňové API. To znamená, že GPU je možné ovládať na oveľa nižšej úrovni, čo má za následok oveľa viac kódu potrebného, aby boli dosiahlnuté podobné výsledky ako pri použití staršieho rozhrania API. Táto práca predstavuje nový framework, vkEasy, ktorý zapuzdruje Vulkan API takým spôsobom, že väčšina jeho funkcií zostáva použiteľná, ale výrazne uľahčuje používanie Vulkan API na vkresľovacie alebo výpočtové operácie. Zdrojový kód obsahuje príklady, ktoré boli implementované pomocou vkEasy, aby ukázali jednoduchosť vkEasy a porovnali ho s kódom napísaným v čistom Vulkane. Bolo pozorované priemerne 94% zníženie potrebných riadkov kódu.

Mobile Robot with Telepresence Control
Svědiroh, Stanislav ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This thesis deals with the proposal and implementation of a robotic platform for the purpose of visual telepresence. The aim of the work is to create a robotic platform remotely controlled by a virtual reality headset, being capable of moving on a flat surface and rotating the camera plaform in two degrees of freedom independently. This work provides a complete solution - both in terms of software and hardware.

Effective C++ Binding for Vulkan API
Ruža, Adam ; Karas, Matej (referee) ; Pečiva, Jan (advisor)
Many 3D graphics applications are developed using Vulkan in C++ language. The major drawback of Vulkan C++ API is slow compilation time. Aim of this thesis is to create Vulkan C++ API with improved compilation time. A custom API generator was implemented for this purpose. This generator allows advanced customization of Vulkan C++ API. Using automated script, compilation times were measured in detail. By reducing unneccesary parts of code for a specific application, we measured improvement of about 50% to 60% in terms of Vulkan C++ API comilation time.

Real-Time Photorealistic Rendering of Voxel Scenes
Flajšingr, Petr ; Matýšek, Michal (referee) ; Milet, Tomáš (advisor)
The subject of this thesis is an implementation of realistic rendering of voxel scenes using a graphics card. This work explains the fundamentals of realistic rendering and voxel representation of visual data. It also presents selected hierarchical structures usable for acceleration and describes the desing of a solution focusing on the representation of voxel data and their rendering. The thesis describes libraries created as part of the project and algorithms. It also evaluates time and memory requirements of the application along with graphical output.
