Application of HS camera to problems of fluid mechanics
Bolcek, Adam ; Elcner, Jakub (referee) ; Jedelský, Jan (advisor)
The main subject of this bachelor thesis is visualization of liquids and gases and their recor-ding with the help of a high-speed camera. The first part deals with types of the high-speed cameras. Also, it is concerned with the description of the Olympus i-SPEED 2 camera which was used for the experiment. Finally, the thesis investigates fundamental parameters of the high-speed cameras and their influence on the recording. The second part describes different methods of visualisation of liquids and gases and also consequent advantages and disadvantages of using each particular method. The last part is dedicated to the creation of my own recording of the visualisation of flowing of gas and its analysis and also to the finding of an optimal setting of the camera and of the lighting of the scene of the recording.

Analysis of chip forming mechanism with a high-speed digital camera
Kopřiva, Antonín ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
The aim of the diploma thesis is to present the main theory concerning high-speed cameras, their usefullness in industry and to present the cameras available at the market. A few experiments have been done focused on the right choice of an objective, lighting of the scene or setting of the cameras. A special equipment has been invented for a better process of measuring followed by experiment aimed at boring a cutter in materials chosen beforehand. The speed and the acceleration of the cutter was ana-lyzed by means of MotionMeasure software in another experiment.

Switching mechanism in the molded case circuit breaker
Mejzlík, Tomáš ; Valenta, Jiří (referee) ; Dostál, Lukáš (advisor)
This paper deals with mechanical switch in circuit breaker designed for low voltage. The goal of this thesis was to analyze switching mechanism both theoretically and practically. Theoretical analysis consist of study different types of switching mechanism and analytical calculations of acceleration speed and trajectory. Practical analysis has been made taking a video with high speed camera of real switching mechanism of a circuit breaker and software analysis of the data. The next part of a thesis is about 3D modeling, animating and simulating of a switchgear switching mechanism.

Use of Video in Physics Education
MASOPUST, Jiří
This thesis deals with the use of the video as a didactic tool in the education of the physics. Introductory part is theoretic and focuses on classification of didactic tools which can be used for physics teaching. Second part analyses the possibility of capturing physical effects, especially effects with very long or very short duration which cannot be captured by conventional devices. This part is focused on the right selection of physical effects, selecting and setting of suitable devices for capturing and further processing of the recorded video. The next section is based on the previous analysis of physical effects, which are recorded and processed into the form of educational movie. The main result of this thesis is the collection of educational movies of fast and very slow physical effects useful as the didactic tool for the teaching of physics.
