Educational tasks for teaching of geometric tolerances
Hanáček, Lukáš ; Foltýnová, Dana (referee) ; Svoboda, Petr (advisor)
The bachelor’s thesis is divided into two main parts. The first one is a theoretical part and it clarifies the basics of geometric tolerancing. The second one is practical and it uses the knowledge gained from the first part to show how geometric tolerances are measured and evaluated. It is demonstrated on a part made especially for the thesis. The measurement uses a device available at the faculty. The purpose of this work is to educatively illustrate the measurement and evaluation of the specifications to students.

Tunable ARC frequency filter
Kufa, Martin ; Murina, Milan (referee) ; Sedláček, Jiří (advisor)
This bachelor thesis deals with ARC frequency tunable filters. The introductory chapter generally focuses on the basic terms of the frequency filters, such as the mathematical expression of the transfer function, types of selective filters, tolerant field, etc. The next section describes the actual higher-order ARC filters and cascade sequencing, especially ARC band reject and possibilities of its implementation. Following is a concrete realization of the ARC filter to band reject with suggestions for tuning the frequency components in the frequency range 10 kHz to 100 kHz and retuning quality factor. Finally, this work contains the printed circuit board (PCB) design of the ARC frequency analog and digital filter section for tuning F0 frequency and quality factor Q setting using digital potentiometers. Furthermore, it also outlines the flowchart of the program for digital control.

Tolerance zone measurement on polarization multiplex
Soktueva, Galsana ; Grenar, David (referee) ; Filka, Miloslav (advisor)
The thesis deals with the measurement of tolerance zone of a polarization multiplex. The theoretical part deals with polarization of light, mathematical description using Stokes and Jones vectors and the representation of the instantaneous state of polarized light using a Poincaré sphere. It also deals with optical transmission and multiplexing. The final part of the thesis describes the design of the measuring workplace and its implementation.

Creation of educational animation for teaching geometric tolerances
Doležalová, Denisa ; Koutecký, Tomáš (referee) ; Foltýnová, Dana (advisor)
This bachelor’s thesis is made out of two parts. First part consists of overview of basic geometrical tolerances, which include their markings, principles and other aspects including basic concepts which fall under norm ČSN EN ISO 1101. Second part is practical, it describes five tasks created for education of geometrical tolerances. Attachment of this thesis includes educational task in form of videos displayed in 3D. Animations show marking of modeled geometrical tolerations, explaining their basic principles and in some cases show ways of their evaluations.
