High Cycle Fatigue Modelling in ANSYS Workbench
Zoubek, Vojtěch ; Řehák, Kamil (referee) ; Dlugoš, Jozef (advisor)
This diploma thesis deals with the extension of the solution of high-cycle material fatigue in Ansys program. The goal of the thesis is creation own algorithm for evaluation of FEA results and overcoming the existing built-in tool. Thesis is divided into theoretical and practical part. In theoretical part, there was created literary research about material fatigue and current solution options. Practical part introduces own algorithm of evaluation.

Parallel Deep Learning
Šlampa, Ondřej ; Sochor, Jakub (referee) ; Hradiš, Michal (advisor)
Aim of this thesis is to propose how to evaluate favourableness of parallel deep learning. In this thesis I analyze parallel deep learning and I focus on its length. I take into account gradient computation length and weight transportation length. Result of this thesis is proposal of equations, which can estimate the speedup on multiple workers. These equations can be used to determine ideal number of workers for training.

Kinematics of a robotic arm by means of geometric algebras
Křápek, Michal ; Hrdina, Jaroslav (referee) ; Vašík, Petr (advisor)
In this thesis we are dealing with forward and inverse kinematics of a robotic arm using a model of two dimensional space in conformal geometric algebra. Goal of this thesis is a proposal of algorithms for dealing with inverse kinematics problem and their implementaion. Five algorithms were constructed and implemented in python language. One for computing a position of a robotic arm and four for calculating the trajectory of the gripper. In this thesis, the problem was solved using a theorem about orientation of the line segment normal and with the triangle signature. Because of that, the cumputing load was reduced in implementation of the most complex algorithm which is combining the motion of the gripper along a polygonal chain and motion of the gripper along circular trajectory. The benefit of this thesis is a new approach to solving inverse kinematics problem.

Systems that Combine Automata and Grammars
Petřík, Patrik ; Křivka, Zbyněk (referee) ; Meduna, Alexandr (advisor)
This work deals with Systems that combine automata and grammars. We investigate their properties compared with grammar systems and automaton systems. Work is focused on systems, which components are finite state automata, right linear grammars, pushdown automata or context free grammars. We also investigate usage of these systems in compilers.

THE CONTROL OF CHAOS: METHODS AND APPLICATIONS
Kořenek, Miroslav ; Dvořák, Jiří (referee) ; Matoušek, Radomil (advisor)
This thesis deals with methods of stabilizing deterministic chaos. The first part provides a brief overview of the problem of deterministic chaos, including the framework used to describe and analyze chaotic systems. Furthermore, the most well-known chaotic systems are described in detail, with the logistic map and the Hénon map selected for experimental stabilization. The description of conventional methods for chaos stabilization, namely TDAS and ETDAS, follows. The principle of their optimization is also explained. Next chapter is dedicated to describing genetic programming and its potential use in chaos stabilization. In the practical part of the thesis, conventional methods and various implementations of genetic programming were applied to stabilize the selected systems. The utilization and experimentation with genetic programming to find stabilizing sequences are the most significant contributions of this work.

Software for modeling concentration profiles during the process of ion implantation and thermal diffusion
Nespěchal, Marek ; Vaněk, Jiří (referee) ; Chladil, Ladislav (advisor)
This thesis deals with the design and development of the CPCalc application used for the visualization of concentration profiles during the process of thermal diffusion and ion implantation. The application was designed with regard to its planned use in the laboratory teaching of material-oriented subjects at the UETE. The theoretical part of the thesis summarizes the technological process of semiconductor manufacturing and deals in detail with the technological processes for doping semiconductors – diffusion and ion implantation. The thesis presents the basic functioning and individual blocks of the CPCalc application, which is developed in the Python programming language in combination with the Tkinter library, a brief characterization of which is also included in this text.

Application for Controlled Access to Remote Documents for Microsoft Windows
Feranec, Adam ; Bartík, Vladimír (referee) ; Rychlý, Marek (advisor)
Cieľom tejto práce je navrhnúť, implementovať a otestovať klientskú aplikáciu pre Microsoft Windows, ktorá bude zabezpečovať prístup k vzdialeným dokumentom pre projekt VDU. Aplikácia je naprogramovaná v jazyku C++ s použitím objektovo orientovanej knižnice MFC, rozhrania WinFsp pre integráciu virtuálneho súborového systému a rozhrania Windows API. Aplikácia k serveru pristupuje cez REST API a je testovaná s využitím vytvoreného simulovaného serveru a testovacieho skriptu, napísaných v programovacom jazyku Python.

Raspberry Pi - Video Control
Bock, Pavol ; Nosko, Svetozár (referee) ; Zemčík, Pavel (advisor)
The goal of this project was to design and implement a video playback controller for the Kodi player. First, existing solutions and products are described and analysed. Based on the analysis a technical product specification is created. Finally, an application is implemented according to this specification. The outcome of the project is a functional application that can be used to control video playback.
