This work includes brief overview of the theory behind two-dimentional languages which was the main theme examined in previous work. Based upon this theory there are next chapters introducing a new concept of three-dimentional and multi-dimentional languages. For each type of language there is a definition of corresponding type of strings and string operations. Finally, for each type of language there are definitions of developed formal gramatics and automata. Along with theory, in work there is an demonstration of developed program, which provides simulation of introduced multidimensional automata.

Thesis is aimed at the possibility of utilization of extreme learning machines and echo state networks for time series forecasting with possibility of utilizing GPU acceleration. Such predictions are part of nearly everyone’s daily lives through utilization in weather forecasting, prediction of regular and stock market, power consumption predictions and many more. Thesis is meant to familiarize reader firstly with theoretical basis of extreme learning machines and echo state networks, taking advantage of randomly generating majority of neural networks parameters and avoiding iterative processes. Secondly thesis demonstrates use of programing tools, such as ND4J and CUDA toolkit, to create very own programs. Finally, prediction capability and convenience of GPU acceleration is tested.

The thesis Diagnostics of rotating electric machines deals with the theory of diagnostics of rotating machines, focusing especially on the diagnosis of asynchronous motors of high power. Due to the importance of maintaining the trouble-free condition of these machines with regard to serviceability, the importance of their diagnosis is growing. Due to inappropriate working conditions or for many other reasons, different types of malfunctions may occur in the machine. The list and the way of occurrence of possible failures are included and explained in this thesis. With the growing age of the machine, it is important to check the insulation status through insulation testing. These tests are performed in the practical part of the thesis and the results are presented. In the case of asynchronous machines, each anomaly leaves a signature in the form of an electrical, magnetic or vibrational signal. These signals are analyzed and evaluated using a specific measuring equipment with the intention of deciding on the current state of the machine. Motor current signature analysis (MCSA) is considered to be the main diagnostic method of asynchronous machines in this thesis. This method is described in detail in this paper and is being applied in electrical engineering.

Thesis solves an issue of application unconventional materials used in horizontal boring machine design. Chosen problem is solved step by step from general selection of suitable material for supporting structure. The selected material is applicated on WFT 13 CNC machine design from production of Fermat and it is created 9 conceptual options of machine’s frame. Finite element method is used for analysis of conceptual options. Based on data from analyses, the best option is selected for constructional part with use of multi-criteria PATTERN method. Constructional part of thesis elaborates on the design of selected conceptual option and gives recommendation for essential processes used in development and production of sandwich structures. The master’s thesis comes with new construction solution for supporting structure of selected machine and especially insight in development and production of new unconventional materials in horizontal boring machines design.

This master thesis deals with the importance of testing of plastic parts in the automotive industry. It defines the basic principles and concepts of project management within product validation, specifies the principles in the corporate environment of ATEK s.r.o. Part of the thesis is the creation of a validation plan and a schedule of labory tests for the selected product from the BMW AG G20 project. The work defines the conditions and the execution of selected tests, eg the climate change test according to the BMW standard PR303.5. The tests are then evaluated. The output from the evaluation is a product optimization proposal.

This thesis deals with safety of the CNC grinding machines. The first part of this thesis is focusing on legislative requirements of EU and Czech Republic, which concern with topic of this thesis. The second part of the thesis is focusing on the safety of the chosen grinding machine. The main parts of the machine which are important for safety are described and then the checklists for verification of the safety requirements are made.

This diploma thesis deals with the design of linear axis for heavy machine tool. The thesis describes the definition of heavy machine tool and its basic construction nodes. The next chapter describes the components of the linear feed assemblages, the basic principles of use and their advantages and disadvantages. On the basis of this research part there are selected variants of the solution and in the last part of the thesis there is a design of the axis X of the gantry machine tool. Part of the work is a 3D model of the proposed feed assemblages and part of the drawing documentation.

Diploma thesis is focused on design and optimalization of log splitter. Thesis consists of search of log splitter types and common used technologies, mechanical design, optimalization, design of propultion system, risk analysis and financial overview. Log splitter is designed to meet needs of automatization. Safety, industrial design and ergonomy has been considered in the design.

The diploma thesis consists of a new design of a controlling procedure for a plastic component of a tank. Its theoretical part deals with the potential sources of errors and uncertainties arising from the measuring itself. It also deals with the characteristics of available CMM devices and includes an analysis of the methods assessing the acceptability of the measurement plan. The practical part analyses systematically the current state and proposes a new solution using a program created using a coordinate machine. A comparison of both variants is presented as an output of the thesis.
