Final machining technology of a special bearing ring using a grinder on the holes
Růžička, Daniel ; Kalivoda, Milan (referee) ; Chladil, Josef (advisor)
The main goal of this thesis is to compare 5 chosen grinding wheels, that vary by the material and structure. The testing is done in the company SLB, spol. s r.o., using a grinder on the holes BDU 80, which is set to 6 different settings of the grinding cycle, defined by the letters A´, A, B, C, D and E. These settings vary by the cutting conditions and enable to compare the tested grinding wheels by 8 measured parameters of the surface quality of the grinded bearing orbits of outer rings of the SLB 84-74 bearings, that are described by the drawing documentation.

Measurement and analysis of the blood flow in peripheral vessels by ultrasound Doppler methods
Lepš, Milan ; Sedlář, Martin (referee) ; Vlk, Daniel (advisor)
Nowadays, the Doppler ultrasonography is an essential part in medicine. With it, we can observe acoustic showoff some tissue associated with Doppler measurement of blood flow parameters. It is still using Doppler devices with a continuous signal which are although structurally and technically simpler, but they are suitable for measuring the speed and volume of blood flow in peripheral blood vessels of the upper and lower limbs. There are calculated physiological parameters from the flow curves that are clinically used for assessing the state of blood supply to the body part. We can determine many values from the flow curves, like peripheral resistance, blood flow in systole and diastole, medium speed, etc. Study group of people are male and female students from 18 to 20 years. Doppler measurements have been performed before physical exercise and after physical exercise.

Driven chaotic oscillators
Pšeno, Daniel ; Guzan,, Milan (referee) ; Petržela, Jiří (advisor)
The theme of this masters thesis are driven chaotic oscillators. The aim of this project is show the various types of driven chaotic oscillator and propose mathematical model solutions using numerical methods. In the first part of this thesis are shown theory of chaos, history of chaos theory, chaotic systems and chaos quantifiers. Next is numerical analysis of differential equations second order by Runge-Kutta fourth order method. Next part contains circuit blocks and synthesis of oscillators. In next part are defined all types of oscillators. Parameters of analysis, equations, circuits and simulations are defined for each type of driven chaotic oscillators. In each subchapter is design electrical circuit. This circuit is simulated and some of them realized.

Pigment
Roudnická, Michaela ; Pitín, Daniel (referee) ; Houser, Milan (advisor)
In my bachelor's thesis I want to explore the possibilities of a painting medium through figural themes of albinism. In a missing pigment I see some king of analogy to painting, which I tried to apply into the medium.

The Multipurpose Sport Hall
Makiš, Daniel ; Pilgr, Milan (referee) ; Buchta, Stanislav (advisor)
The content of this bachelor thesis is design and report the steel roof structure of multipurpose sport hall. The building is located near the city Olomouc. Load-bearing system is made of arch shaped truss girders. The dimensions of the floor plan are 50 x 80 m with the height of the building 10,26 m. There are detailed structural report and drawing made. ČSN EN standards were used for this design and report.

Antialiasing frequency filter
Kocián, Daniel ; Murina, Milan (referee) ; Sedláček, Jiří (advisor)
The bachelor´s work deals with a project of the connecting of the antialiasing electronically turnable ARC filter of the low pass of the fifth order with the Butterworth approximation with the adjustable limited frequency FM in the extent 10 kHz – 100 kHz. The theoretical part includes a short summary and a description of constituent blocks of the complete device. Then the problems of the frequency filters are analyzed there. The practical part consists the project of the printed circuilts of all constituent blocks, then the calculation of all circuited components of ARC filter of the type of low pass for all limit frequencies of the filter. The result of the all work is a device which consists of five blocks and its core is the microcotroler ATmega16. For the electronic turnabling of the filter there are used digital potenciometers. The inseparable part is the enclosed CD-ROM which includes all made materials.
