Materials of football shoes
Ponížil, Ondřej ; Doležal, Pavel (referee) ; Molliková, Eva (advisor)
This thesis is about materials of football boots and possibilities of their technological process. The thesis is divided into three main parts. The introduction part contains the basic facts about football and there is also a description of historical development of the football boots which includes advantages and disadvantages of the structure at that time. The second part presents permeable, flexible and durable materials which can be used to produce the upper part of the boots. In this part there are described attributes of the most common technological process which produces synthetic leathers. The final part is about polyamides and thermoplastics elastomers from which the football soles are made.

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.

The fundamental analysis of the company Pegas Nonwovens
Hladík, Josef ; Kábrt, Tomáš (advisor) ; Cibulka, Jakub (referee)
This bachelor thesis is dedicated to the fundamental analysis of the company Pegas Nonwovens. The purpose was to execute global, industrial and company fundamental analysis and to determine intrinsic value of the stock. Based on the previous, the aim was to suggest an investment recommendation. On global level I analyzed the relationship between the development of significant macroeconomic factors and the stock value. In the industrial part of the analysis I examined the characteristics of nonwovens industry, such as market structure or influence of regulatory authorities. In part dedicated to company fundamental analysis I dealt with calculation of intrinsic value by various methods. Based on the whole analysis and calculated intrinsic value I suggested an investment recommendation, according to which is the stock of Pegas Nonwovens underestimated and suitable for buying.

World production and trade in nonwovens
Strnad, Jiří ; Štěrbová, Ludmila (advisor) ; Tomíček, Luboš (referee)
In the first chapter the diploma work describes the use and production of nonwovens. It proofs the importance and significance of this industry in world economy. In the second chapter there are described barriers of international trade in nonwovens and the need of tariff elimination. Chapter 3 shows consumption, production and foreign trade in nonwovens - globally focused on European Union. In the final chapter the diploma work is focused on the use of nonwovens in the selected sector of hygiene absorbent products.
