Modelovací úlohy - Role strategií při procesu transformace mentální představy do formální reprezentace
GEYER, Jakub
Modeling tasks, consisting in the transformation of a mental image into the formal representation, very often occur in the study of computer science, mathematics, but also in other technical and non-technical fields. From the didactic point of view, it is interesting in modeling tasks (among others), which methods/procedures solvers (students) use to manage more demanding complex tasks. It is often possible to encounter students, who have significant problems solving complex tasks (or they are not able to solve them satisfactorily at all), even though they did not have any problems with similar simpler tasks before during the course. A possible explanation can be seen in the suboptimal use of modeling strategies (e.g. divide&conquer, iterative approach, etc.) or their total absence. This research is focused on the analysis of the role of strategies in modeling tasks, the possibilities of their support/development and teaching methods. The study is conducted, which aimed to analyze the possible impact of strategies in the procedures of university students in solving modeling tasks in the areas of 3D modeling and databases. The goal of the research was also to analyze the possibility of generalization of modeling strategies and their transferability between domains with different type of model.

Design of a 3D print head for mixing additives into cement mixtures
Vícha, Daniel ; Dočkal, Aleš (referee) ; Škaroupka, David (advisor)
The subject of the thesis is the design of a 3D printing head for cement-composite mixtures (concretes). The device enables the addition of the basic component of the mixture by using a liquid solidification accelerator, followed by active homogenization of the mixture and dosing at the printing site. 3D printing of cementitious mixtures often leads to a loss of buckling stability of the printout. Therefore, it is necessary for the printed material to contain additives that accelerate the solidification of the mixture. However, these additives can cause clogging of the hoses when the mixture is pumped into the print head due to premature solidification. Hence, a more suitable solution is to mix these additives in the print head itself. The objective was to develop a 3D print head that allows for homogeneous mixing of the additives in the mixture, thereby eliminating complications associated with pumping. A working prototype of the print head was designed, which consists of a mixing and extrusion chamber. The mixing efficiency of this prototype was verified through numerical simulations using Particleworks. Subsequently, the prototype underwent a mixture experiment without a solidification accelerator to investigate pumpability through the printhead. Based on the numerical simulations, it was determined that the proposed prototype provides sufficient homogeneity of the solidification accelerator with the cement mixture, which should resolve the issues associated with pumping the accelerated mixture. By having a separate mixing chamber, the mixing efficiency can be controlled by adjusting the speed of the motor that drives the mixing shaft. The print head was designed to allow extrusion to be interrupted during print head passes. This was achieved by extruding the mixture into the open space of the chamber using a screw feeder. Therefore, based on the conducted experiments and numerical simulations, it can be concluded that the developed print head has the potential to enhance the quality of 3D printing of cement mixtures and eliminate the problems associated with pumping.

View-dependent Game Mechanics
Zdeněk, Jan ; Polášek, Tomáš (referee) ; Milet, Tomáš (advisor)
The aim of this bachelor thesis is to create a simple computer game in Unity that is based on a change of perspective. Furthermore, this solution includes procedural level generation, which is implemented using the cellular automaton and the marching squares algorithm. The result is thus a game that falls into the roguelike genre, providing the user with the possibility to change perspective from a top-down view to a profile view. The main task of the player is to reach the highest level and, by gradually upgrading the character, gain an advantage for the next run.

3D printing with silver and its use in jewellery
Thomas, Marek ; Langerová, Petra (referee) ; Sučková, Magda (advisor)
Hlavním cílem této práce je najít vhodný typ aditivní tiskárny, která by byla schopna kvalitního 3D tisku stříbrných šperků. Práce seznámí čtenáře s několika typy aditivních tiskáren (FDM, SLA, DMLS a dalších), jejich využitím v praxi a fyzikálním a chemickým chováním stříbra při aditivním tisku. Důraz bude kladen na praktické uplatnění těchto speciálních 3D tiskáren, a to především ve šperkařství. Poslední část práce se pokusí zodpovědět otázku, zda je technicky a ekonomicky proveditelné sestavit a bezpečně provozovat danou 3D tiskárnu v menších firmách či v domácím prostředí.

Implementation of a computer game with themes of board and card games
Haraším, Richard ; Strouhal, Jonáš (referee) ; Vaněk, Vojtěch (advisor)
Thesis presents the design and implementation of a demo version of a roguelite-style computer game that combines elements of board and card games. The thematic focus is on the treatment of purgatory and the phenomenon of mutations. The author explores the possibilities of adapting the genre to new approaches. In particular, issues of automation and procedural environments. Based on his previous work, the author focuses on working with 2D graphics and specific game mechanics. The visuals will work with a dark to horror atmosphere and aesthetic. The goal is to present the complete process of creating a computer game and present a working demo. Part of the overall vision of the project is to design the marketing strategy, business model and how to complete the game into a full version.

3D reconstruction
Vít, Luboš ; Honec, Peter (referee) ; Richter, Miloslav (advisor)
The thesis focuses on 3D measurement using line scan cameras. In response to the emphasis on quality and automatization of production nowadays, the line scan cameras are the appropriate devices providing accuracy for a belt product inspection. The first part of the thesis discusses the desing theory of optics, sensoring and image processing. The realisation of designing a mathematic instrument for evaluation of 3D shape, designing a test workspace and the main sensoring of the scene with processing with basic measuring algorithms is a content of the second part of the thesis.

Performance Evaluation of Graphics Accelerator
Vanek, Juraj ; Drábek, Vladimír (referee) ; Herout, Adam (advisor)
My work is about performance evaluation of graphics accelerator by 3D scenes rendering. It focuses on how to test the performance of the accelerator from every point of view during the performance critical operations in 3D graphics. It deals with implementation problems of individual measures, their influence on total results and evaluation of the measurements. The final output of the application is a score, by which is possible to judge what performance is giving the accelerator in comparison with others. For this comparison is available an on-line results database.
