Neural Network Based Edge Detection
Janda, Miloš ; Žák, Pavel (referee) ; Švub, Miroslav (advisor)
Aim of this thesis is description of neural network based edge detection methods that are substitute for classic methods of detection using edge operators. First chapters generally discussed the issues of image processing, edge detection and neural networks. The objective of the main part is to show process of generating synthetic images, extracting training datasets and discussing variants of suitable topologies of neural networks for purpose of edge detection. The last part of the thesis is dedicated to evaluating and measuring accuracy values of neural network.

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.

Comparison of measurement accuracy of optical and 3D kinematic system
Surkoš, Ondřej ; Adamík, Richard (referee) ; Kundera, Václav (advisor)
The bachelor thesis deals with the comparison of the accuracy of two instruments for measuring the vertical jump, using a different measuring principle, namely "Optojump next" and "BTS Smart DX". In the theoretical part, the individual devices are discussed, on what principle they work and are compared with each other. In the practical part we deal with the methodology, processing of measured data and evaluation of the results of measurements.

Historical development of the selected parcels in the cadastral unit of Slatina
Klinčík, Radoslav ; Zvolská, Hana (referee) ; Berková, Alena (advisor)
The task of the bachelor thesis was to survey the current state of planimetry in cadastral area of Slatina and to compare the planimetric survey with the valid state of the cadastral map. The bachelor thesis also deals with the historical development of assigned plots from 1968 to the present state of the cadastral map. The survey of historical development utilized the results of surveying activities based on survey documentation of the Cadastral Office of the City of Brno. Reconstruction of the historical development took place by means of graphic processing, testing of accuracy and transformation according to point 13 of the Annex to the Cadastral Decree No. 357/2013 Coll. On historical development we can see that the boundaries of the plots in the current cadastral map are determined correctly. The result of the work can be used by the owners to help resolve the mistakes, which they find on their land.

The Machines and Tools for the Fineblanking Technology
Šindelka, Marek ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This work provides a brief overview of the used machines and tools designed for fineblanking. Fineblanking is a technology from the field of the surface forming, suitable especially for mass production, which can be used to make a functional component in a single operation. This work also lists the various methods of precision cutting, and describes the tools, that are the main reason for the quality of the product. Furthermore, in this work are listed some examples from today in practice used machines and their planting into the entire complex of production lines.

Control of linear drives HIWIN
Roman, Jan ; Kaván, Martin (referee) ; Houška, Pavel (advisor)
The diploma thesis deals with three phase linear synchronous electric motors mounted on linear drive, its system of sensors and control. The analysis of working principle and classification of linear motor was done in the beginning part; analysis of the drives sensors system was made in the following chapter. The thesis also deals with the driver from the automation point of view, its tuning and behavior according to high dynamics and precise positioning. The last chapter discusses the issue of controlling two linear drives. Whole thesis was realized on a borrowed linear motor with driver from HIWIN corp.
