Realistic Visualisation of Alcoholic Beverages Using Distributed Raytracing
Fabík, Jiří ; Maršík, Lukáš (referee) ; Polok, Lukáš (advisor)
This work is about a realistic visualization technique called raytracing. It studies its original form, its extensions and optimizations. Raytracing casts rays through pixels and follows their propagation in the scene, according to the physical laws. It enables rendering of correct shadows, reflections and refractions. Distributed raytracing serves for better visualization and advanced effects. One ray is replaced with a beam of rays that allows soft shadows, fuzzy translucency, depth of field and antialiasing. With the increasing number of rays, the render time rises as well, so it is needed to use some optimization techniques and tools. A way of using this rendering method for visualization of alcoholic beverages is also described.

Plastic optical fibres and their application in practice
Bubela, Ondřej ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
The intention of this essay is familiarize readers with polymer optical fibers knowed as POF. Listing the losses factors (attenuation, dispersion) and transmition properties (bandwidth, index profiles). Describes production POF (suitable materials and methods), connecting with detachable and not detachable joints. Discuss and compares diference between GOF and POF. By measuring demostrates the complexity of compilation POF and GOF physical layers. Define the facts affecting transmission parameters. Trying to inform about economical possibilities.
