Automatic Image Analysis for Production Quality Control of Textile
Sýkorová, Tereza ; Dobeš, Petr (referee) ; Zemčík, Pavel (advisor)
This work deals with the classification of defects that occur in the production of nonwovens. The defect classification task is part of a system for automatic production quality control. The goal is to implement a method that will classify problematic defect classes with sufficient accuracy. That was achieved using convolutional neural networks (CNN). The best results were achieved by the EfficientNet network, which had an accuracy of 81% when evaluated by cross-validation on an available dataset. Within the work, a number of experiments are performed, which are focused on the modification of input data. The influence of the shape and composition of the input images on the final classification is examined. A CNN model was also implemented, which uses additional information for classification in addition to the image.

Geological and geotechnical characterisation of the mining environment - URF Bukov II - Interim report II
Bukovská, Z. ; Rukavičková, L. ; Chabr, T. ; Morávek, R. ; Levý, O. ; Sosna, K. ; Souček, Kamil ; Vavro, Martin ; Zelinková, T. ; Dobeš, P. ; Švagera, O. ; Kryl, J. ; Soejono, I. ; Řihošek, J. ; Holeček, J. ; Hanák, J. ; Čermák, F. ; Kašpar, R. ; Mareček, L. ; Nedvěd, J. ; Vavro, Leona ; Waclawik, Petr ; Staš, Lubomír ; Myška, O.
This report describes the work carried out in the second year of the public contract Geological and geotechnical characterisation of the rock environment – PVP Bukov II. The\ncharacterisation and descriptive works are directly related to the excavation of the premises for the future underground laboratory. These include in particular: geological and geotechnical documentation of the faces and walls of the workings, petrographic, mineralogical and structural geological documentation, hydrogeological characterisation of the environment, as well as determination of the physical and mechanical properties of the rock mass in situ and in the laboratory, geophysical characterisation and monitoring of the seismic effects of blasting and hydrogeological monitoring. An important part of this report is preparation of the classification system used to describe the rock mass. The report also includes a brief overview of the work planned for the third year of the project.

Generative Neural Networks for Handwritten Text
Ševčík, Pavel ; Dobeš, Petr (referee) ; Hradiš, Michal (advisor)
The aim of this study was to create a generative neural network for handwritten text lines. The model produces variable-sized images of handwritten text lines based on the expected style. The proposed method exceeds existing models in the image quality and can be used to generate both individual words and entire lines of handwritten text. It combines the use of the attention mechanism to extract the features for each character from the text query and their arranging on the line by inserting spaces between them. The new approach allows more granular control of the symbol positions on the line, which leads to smoother style interpolations. In contrast to the previous approach, the proposed method uses the Gaussian filter to spread the individual symbols features to the surrounding area. This approach also allows to train the model for symbols position predictions using the adversarial loss (GAN). In addition, annotations of symbol horizontal positions on the lines of the IAM dataset of handwritten text have been created.

Effectiveness and utilisation of the European Structural funds
Dobeš, Pavel ; Rovná, Lenka (advisor) ; Perlín, Radim (referee)
Diploma work "Effectiveness and utilisation of the European Structural funds in Czech Republic on case study of Single Programming Document objective 3" is divided into three main parts. I have used comparative method of primary and secondary sources. This thesis should answer the question whether the Czech Republic is prepared for getting money that is offered from the EU. If not, what is the purpose of this status and what are the recommendations? As a conclusion of this work is that Czech Republic, at least in respect of Single Programming document that is used only in Prague, is quite ready and there are some problems that should be solved before the next programming term 2007-2013. Among these problems belong publicity, n+2 rule and monitoring system. At the end of the work is list of recommendation that should be changed for better effectiveness of Single programming document that is transforming into Operation Program Prague Adaptability.

Consequences of NAFTA Trade Agreement for the Car Industry in North America
Dobeš, Petr ; Kozák, Kryštof (advisor) ; Fiřtová, Magdalena (referee)
The subject of this thesis is the North American Free Trade Agreement (NAFTA), signed between the United States of America, Canada and Mexico and its impact on the automotive industry in North America between the years 1994, when NAFTA came into force, and 2009, when two major American car manufacturers, General Motors and Chrysler, went bankrupt during the global-scale recession and the industry changed significantly. The thesis is based on the theory of comparative advantages, as it was described by a British economist David Ricardo in the 19th century. It subscribes to the general principle that a free trade is beneficial to all engaged parties, because it enables more effective allocation of resources and provides for more specialization of production. The thesis argues NAFTA was a complex and ambitious international trade deal that had profound impact on the evolution of this branch of industry in the United States, Canada and Mexico, however its impact on the economy as a whole was limited and many of the changes, attributed to NAFTA, would likely have happened even without its passage due to the natural process of evolution of the industry and modernization. The creation of a continent-wide zone of free trade enabled local and foreign car makers to establish international supply chains that...
