Fitness Map Application
Hrůza, Tomáš ; Drga, Jozef (referee) ; Rozman, Jaroslav (advisor)
As the world continues to evolve and expand, the need for modern solutions rapidly grows. Large portion of the population tends to keep track of their lifestyle which in turn provides an opportunity for companies to create many different fitness devices and applications. The goal of this bachelor's thesis is to provide a new kind of motivation to get out into the world, provided by yet another web application. However this application provides its user with motivation in the form of a minigame - the user travels through the world and the application then calculates the area he captures using a Voronoi diagram based on his route. Another feature the application provides is viewing your routes in a merged, averaged form. This comes in handy when the user would like to approximate his actual route over several different activities. The first part of this bachelor's thesis collects information about different commonly used fitness applications. Out of all those a web application called Strava was chosen as a base for collecting user data. The resulting web application connects to Strava using OAuth and retrieves routes the user has collected using the Strava mobile application. One of the last chapters focuses on describing the implementation details about used and created algorithms. It additionally contains description of scripts which were used to extract data out of OpenStreetMap database and calculate Voronoi regions based on them. To store and search through calculated regions, a MySQL database is used. The application is developed using modern frameworks and is heavily oriented around a comfortable user interface and responsive web design.

The Call of the Wild
Serbousková, Lucie ; Sedláčková, Kateřina (referee) ; Kratochvíl, Jan (advisor)
Recreation is undergoing great changes nowadays, people are again longing for nature, which gives them peace and rest from everyday worries. However, recreational areas in the Czech Republic often do not meet the requirements of today. One such requirement is that the area should be barrier-free and provide facilities for cyclists. The work focuses on the Elbe Trail, which is popular not only in the Czech Republic but also attracts a large number of foreign cyclists. However, there is not a sufficient network of campsites to provide sufficient facilities for them. The design of the new site in Bílá Třemešná corresponds to all these aspects and with its modern nature-inspired appearance provides attractive facilities not only for cyclists, but also for visitors to the Královédvorská Zoo and all those looking for a quiet place for a break from today‘s hectic times.

Procedural Generation of Voxel Models
Hypeš, Tomáš ; Matýšek, Michal (referee) ; Milet, Tomáš (advisor)
This thesis deals with procedural generation techniques and its use in the creation of voxel models. The techniques that have been used are Perlin Noise, Voronoi diagram, L-systems etc. This knowledge is then used to create a world generator for computer game with open world. This game provides players with the ability to modify this world and use its creativity, for example, in building construction. The game, however, will not give to the player all options for free, but for example for build, he or she will first have to find and mine the material. The game has been written in programming language C++ with the use of libraries Boost, SDL and OpenGL.

Computational analysis of the influence of initial defects on the ceramic foam failure upon mechanical loading
Papšík, Roman ; Majer, Zdeněk (referee) ; Ševeček, Oldřich (advisor)
The thesis deals with computational modelling of ceramic foams and analysis of influence of structural manufacturing defects (like broken struts, closed pores and material clumps) have on foam strength. Model of foam geometry was discretized using beam elements in order to decrease computational cost. In place where several struct join, rigid beam element was used so that the increased stiffness is better modelled. Closed walls of pores were modelled and discretised by shell elements. Influence of loading direction was analysed on foams containing no defects and then influence of amount of defects in foam on strength was further analysed. Highest strength show foams created by cells whose structs are oriented in direction of loading. These were losing strength most rapidly. Foam with structure of rhombic dodecahedral cell was least influenced by presence of closed pore defects but it also showed lowest strength even without defects. Cells with struts oriented in direction of loading experienced biggest drop in strength. Kelvin cell is a compromise. It was shown that difference in strength of strut with constant and varying cross-section is tenths of percent.

Advanced simulation methods for reliability analysis of structures
Gerasimov, Aleksei ; Lehký, David (referee) ; Vořechovský, Miroslav (advisor)
The thesis apply to reliability problems approach of Voronoi tessellation, typically used in the field of samples designs evaluation and for Monte Carlo samples reweighing. It is shown, this general technique estimation converges to that of Importance Sampling method despite it does not rely on Importance Sampling's auxiliary density. Consequently, reliability analysis could be divided into sampling itself and assessment of simulation results. As an extension of this idea, adaptive statistical sampling using QHull library was attempted.

Modelling of the randomly formed ceramic foam structure for FEM simulations
Papšík, Roman ; Navrátil, Petr (referee) ; Ševeček, Oldřich (advisor)
This bachelor thesis deals with construction of ceramic foam model with various levels of (ir)regularity for finite element simulations in Ansys. The main objective is to substitute the complex structure of the open cell foam using the beam elements, enabling to perform FE analysis on much larger volumes of foams than the realistic foam models composed of solid elements. In this work, the technique of the model creation is based on the Voronoi tessellation and enables choice of arbitrary (ir)regularity of the modelled structure. The created source codes generate the model data directly in the syntax of APDL language for FEM system Ansys. The first part of the work describes several methods of the space partitioning and methods for substitution of the real foam structure by simplified “wire” model. The second part defines the Voronoi tessellation (diagram) as a key technique for creation of the foam model and describes its algorithms. The next part of the work deals with possibilities and utilizations of various software and libraries, describes creation of the own code in mathematical software Matlab and way how to transfer the model data into the system Ansys. The last part of the work demonstrates functionality of the created model on several FEM simulations, studying response of the ceramic foam on the external mechanical loading, upon consideration of various levels of the foam structure irregularity.
