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.

Combined Global Navigation Satellite System Module
Jurajda, David ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
The thesis objective is design of methodology focused on accuracy measurement in field of GPS/GLONASS receivers. Text is devided into five main parts. The first one is focused on GNSS technology. Second one deals with used coordinate systems and map projections (ETRS89, WGS84, UTM, Gauss-Krüger). Next part discusses statistical methods. Part four is focused on hardware. Then the final part describes experiment realization and obtained data analysis.

State of the art speech features used during the Parkinson disease diagnosis
Bílý, Ondřej ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
This work deals with the diagnosis of Parkinson's disease by analyzing the speech signal. At the beginning of this work there is described speech signal production. The following is a description of the speech signal analysis, its preparation and subsequent feature extraction. Next there is described Parkinson's disease and change of the speech signal by this disability. The following describes the symptoms, which are used for the diagnosis of Parkinson's disease (FCR, VSA, VOT, etc.). Another part of the work deals with the selection and reduction symptoms using the learning algorithms (SVM, ANN, k-NN) and their subsequent evaluation. In the last part of the thesis is described a program to count symptoms. Further is described selection and the end evaluated all the result.

Band Gap - accurate voltage reference
Bubla, Jiří ; Petržela, Jiří (referee) ; Kolka, Zdeněk (advisor)
This diploma thesis is specialized on a design of a high accuracy voltage reference Bandgap. A very low temperature coefficient and output voltage approx. 1,205V are the main features of this circuit. The paper contains a derivation of the Bandgap principle, examples of realizations of the circuits and methods of compensation temperature dependence and manufacture process, design of Brokaw and Gilbert reference, design of a testchip and measurement results.
