Measurement of the vibrations
Diblík, Jan ; Kolouch, Jaromír (referee) ; Biolková, Viera (advisor)
Diploma thesis is focused on principles of measuring the vibrations using accelerometers and using them for making vibration measuring instrument with focus on modern integrated digital accelerometers. In the first part are described ways to measure acceleration and vibrations with available technical supplies with respecting place and purpose of measuring. In practical part are measured characteristics of used sensor, instrument for measuring vibrations is designed and built and for few experimental object vibrations or acceleration are measured and graphical interpreted.

Digital pendulous inclinometer
Famfulík, Lukáš ; Kolka, Zdeněk (referee) ; Biolková, Viera (advisor)
The aim of the bachelor’s project is an analysis of functional and technical requirements as digital deck device. The construction and the functional sample of measuring device was realized on the basis of analysis. The device can communicate with PC via USB. The measure sensor is manufactured with the use of MEMS technology.

Design of a pressure monitor for biomedical applications
Tenora, Jan ; Kolka, Zdeněk (referee) ; Biolková, Viera (advisor)
The goal of this bachelor’s thesis was to gather requirements for the realization and functional features of the proposed pressure monitor. Based on the collected requirements, the block diagram and also the complete schematic were proposed. Then the printed circuit board was designed, made and fitted. This board was placed into prepared box together with other components. Finished equipment was tested, set and also precision was checked by its measurement. Finally, user guide and also service manual were written.

Model of Properties of Dynamic Systems
Sztefek, Jan ; Kolka, Zdeněk (referee) ; Biolková, Viera (advisor)
The thesis deals with modeling algorithm for mathematical description of dynamical system written in status description, which makes it possible to changing coefficients status array A, B. Algorithm is programmed in MATLAB-SIMULINK environment. Dynamical system in this thesis is side movement of plane in space. Created program don’t deal with changing coefficients of status array A, B only, but it deals with automatic change this coefficients when surveyed output function exceed requested limit too. Among others the thesis is focused on dynamical properties of plane, inference of theorems, linearization and derived side movement. Last but not least this thesis deals with analysis and approximation of side movement. This all is made for possibility of derive final status movement of plane. The thesis is supplemented for detail description created program and user guide for work with program, which make it possible to easier usage for ignorant peoples. The end of thesis is supplemented for tested simulations of side movement of plane in space with usage real data. All this simulations are real so it’s possible to claim that program works correctly.

Wireless transfer of the sensor data
Kičina, Andrej ; Maršálek, Roman (referee) ; Biolková, Viera (advisor)
Thesys is focused on wireless transfer of the sensor data. It describes different wireless standards for potential use and realization of interface between sensor's data and their transfer. Crux of the matter is in detailed description of whole system with created utility programs. In the end it is summarized acquiered features of the realization.

Laboratory Model of the Vortex Speed Indicator
Kazda, Ondřej ; Kolka, Zdeněk (referee) ; Biolková, Viera (advisor)
This work is concerned with posibility of measuring a wind flow by Von Karman vortex sheed structure. The bluff body is situated in the way of air flow propagation and consequentally vortexes will be appeared. Important part of speedmeter design is measurment chamber must allow to vortex sheed propagation. The transient and the reciever are situated vertically to propagation of flow.The Ultrasonic carrier is transmitted and modulated by freqency of vortex sheeding in measurment chamber.Demodulator uses PLL to “focusing“ detection of the ultrasonic beam. This can be indicated like lock and unlock phase loop. From known value of sheed frequency can be directly calculated speed of flow.

Frequency filters controlled via microprocessors
Bronec, David ; Kincl, Zdeněk (referee) ; Biolková, Viera (advisor)
This thesis is focused on the microprocessor-controlled frequency filter project. The main goal of the thesis is to present basic terms and principles of frequency filters and active frequency filters for cascading synthesis. Furthermore, the work contains information on digital potentiometers. The thesis includes circuit simulations and a project of connecting with a printed circuit board. The last chapter contains the results of the measurements.
