This thesis deals with problems of recognition of an electrometer´s state from sensing image. It is tangibly about electrometer´s scanning by a mobile phone´s camera. There is a surface with an electrometer´s dial which is detected and on this surface the particular numbers are detected consequently. The numbers are recognized via neural network. For more information from this image there are used some techniques of image segmentation to check the status. For the classification of the segmentation´s outputs are used classification tools, especially a support vector machine (SVM) and neural networks. Problems of image segmentations are solved by using OpenCV library. OpenCV is used for the implementation of the vector machine either. Application is on Android platform. Part of the thesis is concerned in a creation of a desktop application which is instrumental towards testing of neural network. The thesis also describes how to save the necessary data gathering in the course of the recognition which are used for working with neural network. The part of the thesis also deals with running web which will be evolved for the opportunity to participate in the further development of the system. There is available a public repository with source codes created during implementation.

This thesis deals with the means of mechanization for maintenance of permanent grassland by mowing without collection or mulching. The means of mechanization belongs to category of the one axle tool carrier and the zero turn mower. The aim of the study is practical comparison of the means of mechanization and their suitability for different grassland. The practical part of study deals of functional and operational aspects. Futher, the machines were compared in terms of operating cost. The machines are assigned to suitable operators, on the basis of this analysis.

In present diploma thesis called The Problem of Communication between Man and Machine in Contemporary Visual Culture I will analyse the movie by Spike Jonze called Her (2013), in which the topic of interconnection between Artificial Intelligence and real human world is presented. I will deal mostly with the themes of virtual reality and communication between man and computer. The thesis is divided into two parts. The first is based on the analysis of chosen theories of new media in order to reveal the theoretical foundation of the theme of interaction between the man (as human body) and machine (as computer); also I will analyse the development in the fiedl of AI to describe various forms of human-computer communication. The second part of the thesis is based on the case study/analysis of the movie Her, in which the theme of communication between human and computer is presented. In the first part of the thesis I will follows ideas of Lev Manovich, Marshall McLuhan, Pierre Lévy, Paul Virilio, John Searle, Jakub Macek and Mark B. N. Hansen. Keywords Machine, artificial intelligence, virtual reality, new media, computers, internet

Theme of this thesis is the passing nature of things or ``impermanence{\crqq}. The theoretical part of thesis, it covers the philosophy of the theme and give personal view on the theme of impermanence, using quotes from experts in the field of philosophy. It discusses the sections chosen for the practical part of the thesis. The practical part of this thesis is divided in five basic sections {--} man, animal, tree, machine and rock. The next theoretical parts are devoted to colours, textures of material, action painting and gestical abstraction. The application of the techniques and processes in teaching is discussed. In conclusion, I give my personal interpretation of the theory and apply it to this thesis. The practical part of this thesis consists of a cycle of 10 paintings (60 x 80 cm) in acrylic. The cycle is devoted to man, animal, tree, machine and rock in relation to the central theme.

The dissertation analyzes the work technology in the processing of fast growing poplar trees and similar trees. In the experimental section were described two different methods of processing the lines of fast-growing poplar trees. It was further verified by the performance and suitability of use Doppstadt AK 450 shredder processing fast-growing poplars and similar trees.

This master’s thesis is focused on design of stepper conveyor, that is used for transport od round bars of lengths from 3 m to 12 m and diameters from 20 mm to 100 mm between chamfering machines. It is a machinery assembled from chain conveyors and roller conveyors, which allows transverse and lengthwise movement of bars. The main goal was reduction of energetic demands compared to present solution of conveyor.

Tato práce řeší návrh komplexního modelu asynchronního stroje, pomocí něhož se dá stroj analyzovat. Model se skládá z dílčích modelů, které popisují asynchronní stroj z hlediska elektro-magnetického, elektrického a tepelného. Elektromagnetický model je řešen pomocí metody koneč-ných prvků v programu zvaném FEMM. Další výpočty jsou provedeny pomocí Matlabu. Tepelný model počítá s ustáleným stavem stroje v požadovaném pracovním bodě. Elektrický model je řešen pomocí náhradního schématu, ze kterého jsou odvozeny vztahy pro elektrické veličiny. Výsledný propojený model je naprogramován v Matlabu a slouží jako nástroj pro analyzování asynchronního stroje.

This diploma thesis describes realization and testing on-the-fly measurement using tracking interferometer. This measurement enables to achieve higher amount of measured points and decrease time of machine tool calibration. Calibration and verification values of machine parameters, as well as time of measurement and other details of this method are compared with results of conventional method called trigger. To evaluate the quality of volumetric compensation created from calibration values, we use verification measurement of circular interpolation.

This thesis is dealing with determining of technical and economical limits of axis X of portal milling machine driven by gear rack and pinion. And designing drive of axis like this. In chapter overview of the current state of knowledge are researched options of drive systems of linear axis, primarily of using ball screw and couple of pinion and gear rack. Basic parameters of axis X portal milling machines, options of measuring, guiding of axis and electric motors. Then the limit suitability of using pinion and gear rack is determined. In next chapters is designed few variations of arrangements of drives and selected the best one. This arrangement is then designed.

The aim of this work is to determine the influence of noise on determination of own frequen-cies for machine tool by operational modal analysis. For the assigned machine tool operation-al analysis is performed using Data-Driven and Covariance-Driven method for multiple exci-tation variants. Based on the results are created stabilization diagrams used to determine ma-chine tool own frequencies. The results for each excitation variant are compared to each oth-er and the effect of noise influence on the results is determined.
