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.

Speech Recognition (digit)
Kantar, Martin ; Minář, Petr (referee) ; Matoušek, Radomil (advisor)
The aim of this diploma thesis is to explain what speech is and what are its constituents. I mention commonly used methods which are used for preparation of signals which we use for recognition. Schematic examples show principles of current recognizers of speech, their advantages and disadvantages. I made speech recognition program for 0-9 numerals in Matlab for neural nets learning.

London Eye
Hušek, Martin ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
Performance of static analysis of the London Eye structure is the subject of this diploma thesis. First chapters of the thesis analyses overview of realized structures of the Ferris wheel. The main part of the thesis analyses the London Eye structure itself. Specifically are described response analyses, sensitivity analyses, analyses of ultimate limit state and serviceability, stress analyses, analyses of fatigue stress and lifetime analyses. The thesis describes among static analysis also a design of dynamic vibration absorbers. The results of each analysis are evaluated in the final chapters.

Automatic Documentation Generation through Product Parameterization
Slechan, Martin ; Hedrlín, Petr (referee) ; Videcká, Zdeňka (advisor)
This bachelor thesis solved the implementation of automatic document generation using product model parameterization. The theoretical and analytical part is followed by a suggestion for process optimization, where it was monitored what positive and negative impacts in the possible implementation of automatic generation in the company's internal processes may arise. The evaluation was based on calculations and the results show that the implementation of automatic document generation can optimize and automate the process, reduce possible errors and costs. In the end, all types of licenses of the used program were compared and the most suitable for the analyzed process was selected.

Parametrical analysis of sound
Matuštík, Daniel ; Sigmund, Milan (referee) ; Zelinka, Petr (advisor)
This bachelor's thesis deals with the processing of acoustic signal. The work includes theoretical models for the processing and classification and shows the spectrogram fuss and cans in different surroundings. Propose here a general procedure for creating a system that includes parametric analysis of the acoustic signal.The Theoretical part of work serves as a preliminary to a recognizer in the programming environment MATLAB.

Library for Python used for dysarthric speech parameterization
Koutný, Tomáš ; Galáž, Zoltán (referee) ; Mucha, Ján (advisor)
Bachelor thesis is focused on parameterization of dysartoric speech. Attention is paid to methods of Speech Signal Analysis for Parkinson's disease, modern parametrization techniques, which are designed to quantify the damage of motoric aspects of speech and implementation of selected parameters in Python. The main goal of this work was to create a parameter library that is realized in the PyCharm development environment.

Commands for 2D plotter
Maštera, Martin ; Foukal, Roman (referee) ; Štohl, Radek (advisor)
This work deals with parameterized 2D plotter, which function is to draw arbitrary shapes, which are loaded from a PostScript file generated from AutoCAD. From that file are gained data, which are converted into shapes parameters. Communication between PC and PLC is provided via an OPC server from Rockwell Automation. In RSLogic 5000 application, which is used to program PLC from Rockwell Automation, is created program to draw individual shapes on paper.

Parametrizace rozdělení škod v neživotním pojištení
Špaková, Mária ; Pešta, Michal (advisor) ; Cipra, Tomáš (referee)
Title: Parameterization of claims distribution in non-life insurance Author: Bc. Mária Špaková Department: Department of Probability and Mathematical Statistics Supervisor: RNDr. Michal Pešta Ph.D., MFF UK Abstract: This paper deals with the parameterization of claim size distributions in non-life insurance. It consists of the theoretical and the practical part. In the first part we discuss the usual distributions of claims and their properties. One section is devoted to extreme values distributions. Consequently, we mention the most known methods for parameter estimation - the maximum likelihood method, the method of moments and the method of weighted moments. The last theoretical chapter is focused on some validation techniques and goodness-of-fit tests. In the practical part we apply some of the discussed approaches on real data. However, we concentrate mainly on the large claims modeling - firstly, we select a reasonable threshold for our data and then we fit the claims by the generalized Pareto distribution together with the introduced parameterization procedures. Based on the results of the applied validation methods we will choose appropriate models for the biggest claims. Keywords: parameterization, non-life insurance, claims distribution.
