Data Mining with Python
Šenovský, Jakub ; Bartík, Vladimír (referee) ; Zendulka, Jaroslav (advisor)
The main goal of this thesis was to get acquainted with the phases of data mining, with the support of the programming languages Python and R in the field of data mining and demonstration of their use in two case studies. The comparison of these languages in the field of data mining is also included. The data preprocessing phase and the mining algorithms for classification, prediction and clustering are described here. There are illustrated the most significant libraries for Python and R. In the first case study, work with time series was demonstrated using the ARIMA model and Neural Networks with precision verification using a Mean Square Error. In the second case study, the results of football matches are classificated using the K - Nearest Neighbors, Bayes Classifier, Random Forest and Logical Regression. The precision of the classification is displayed using Accuracy Score and Confusion Matrix. The work is concluded with the evaluation of the achived results and suggestions for the future improvement of the individual models.

Cold spray technology as a tool for repairing of worn parts
Hevessy, Zoltán ; Heczko, Martin (referee) ; Doubrava, Marek (advisor)
Cold spray (CS), also known as cold dynamic gas spraying, is a state-of-the-art process from the thermal spray family, characterized by a combination of low temperature and high velocity of the particles, which makes coatings of sufficient quality for applications in many industries where other processes cannot be used, including repairs of civil and military aircraft and helicopters. The bachelor thesis presents a detailed description of this process, the influence of its parameters on the quality of the coatings, examples of repairs and evaluation of the mechanical and corrosion properties of the repaired parts.
