Analysis of Classification Methods
Juríček, Jakub ; Zendulka, Jaroslav (referee) ; Burgetová, Ivana (advisor)
This work deals with the classification methods used in the knowledge discovery from data process and discusses the possibilities of their validation and comparison. Through experiments, the work focuses on the analysis of four selected methods: Naive Bayes classificator, decision tree, neural network and SVM. Factors influencing basic characteristics such as training speed, classification speed, accuracy are examined. A part of the thesis is a desktop application, which is a tool for training, testing and validation of individual methods. Eleven reference data sets are selected for experimental purposes. At the end of this work experimental results of comparison and observed characteristics of classification methods are summarized.

Contactless temperature measurement
Závodný, Ondřej ; Bejček, Ludvík (referee) ; Beneš, Petr (advisor)
In this bachelor thesis I outlined the problems of non-contact measurement and practical verification of the basic parameters thermo camera Fluke Ti20. It is especially on the experimental measurement of the source of the reference temperature and the product to demonstrate the impact of emissivity. The aim of this work is a practical verification thermo cameras parameters, the determination of uncertainties and to explore the effects of parasitic repeated measurements. The basic part is a brief recorded history, the general relations and principles of the non-contact measurement, as well as their own use and typical parameters. In the next chapter you more acquainted with itself thermo camera, properties and basic parameters. The practical part is about the measurement itself. The main objective then was to verify the accuracy of reported thermo camera and examining the impact of emissivity.

Flow measurement
Schoř, Zdeněk ; Boček, Petr (referee) ; Beneš, Petr (advisor)
This bachelor thesis deals with flow measurement of liquids. The first part is a theoretical analysis with an overview of the most important parameters of flow sensors, the main parasitic influences and methods for calibration of flow sensors. The second part is the design and realization of the laboratory apparatus for measuring the flow of water, which is intended for the teaching of students. The apparatus is designed to test four flow sensors using weighing reference. The result of the practical part is the measurement of the basic characteristics of the flow sensors used and comparison of the obtained values with the data from a manufacturer. Further parasitic influences are added during the measurement and is determined to what extent they affect accuracy of the measurement.
