Mechanical design of mobile camera system via electric drive
Bosák, Dalibor ; Brandejs, Jan (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with an overview of accessories for a camera movement and mechanical design of a mobile camera crane via electric drive. In the construction part of the thesis are primarily brought conception designs of a camera crane including stress analysis in each places of the crane and then the proposal itself according to the chosen concept. There are shown solutions of individual parts of the camera crane with their description and views. In the end of the thesis are resumed the advantages of the design and economical analysis including the prices of each components and the whole crane.

Inclinometers and Gyroscopes
Hývnarová, Irena ; Beneš, Petr (referee) ; Havránek, Zdeněk (advisor)
This study deals with tilt sensors. Besides others methods, accelerometers and gyroscopes are also convenient to solve this problem. Tilt sensors which are described in this thesis are working with capacitive, piezoresistive and thermal method. Capacitive accelerometers from producer Analog Devices, STmicro and Freescale, piezoresistive accelerometers from producer Panasonic Matsushita and gyroscope ADXRS300 are tested by practical measurement. Parameters of these accelerometers are found and they are compared with parameters from producer. Measurement reliability in this study is analysed as well. This thesis is divided in chapters theoretically describing principles of particular accelerometers and the chapters containing measured data evaluation.

Tetris 3D - made of array LED diode
Paták, Pavel ; Pust, Radim (referee) ; Šebela, Radek (advisor)
This thesis deals with suggestion of device for playing tetris game in 3D. There is used 3D LED display – the ashlar where the LED are situated in its volume. Thesis describes possibilities of display connection with a view to minimal number of control pins. It also describes display mechanical construction. Motion of blocks in the game is controled by tilt of device, thesis describes way of tilt measuring. It also decribes in details possibilities of connection of the microcontroller and the display, comparison of connection ways, sellection of one of these solution and sellection of the microcontroller. There is also noted the structure of control software.

Evaluation of pulse wave velocity in the human body
Mezuláníková, Radka ; Viščor,, Ivo (referee) ; Jurák, Pavel (advisor)
This Mater's thesis deals with the evaluation of pulse wave velocity using multi-channel whole-body impedance cardiography. Data were taken from the group of healthy volunteers whose impedance changes were measured during rest, respiratory maneuvers, tilt and stress exercise. The result of this measurement are values of peaks of pulse wave time shifts towards R-wave. The velocity values towards the thorax electrodes were recalculated on the basis of knowledge about the pulse wave time shifts and the distances from the heart to the scanned locations, which were measured using the arterial segment's lengths.

Proposal control system motorcycle to suppress riding errors leading to accidents
Přibyl, Tomáš ; Liška, Jiří (referee) ; Zuth, Daniel (advisor)
Work tackles the general design systems of automatic control of engine power and braking effects so that avoid any unnecessary dangerous situations and to improve the driving characteristics and suppression causes of accident due to bad decisions of driver. Is required to propose a general system based on the draft sensors and control circuits, their relationships, design control processor, which will be without the knowledge of the driver intervene in driving motorcycle.

Controlling of camera
Tylš, Ladislav ; Valach, Soběslav (referee) ; Richter, Miloslav (advisor)
This thesis describes the principles of making application which is able to set and control camera. The first part describes basic camera connections and it explains definition and specification of camera’s features. The second part of my thesis describes implementation of application, which can use more cameras to image preview, image acquisition and to simply set of camera’s features. To implement the applications we can use MATLAB and C++BUILDER uses opencv libraries.

Fast Re-Calibration of PTZ Camera for Traffic Analysis
Dřevo, Aleš ; Juránek, Roman (referee) ; Sochor, Jakub (advisor)
This thesis deals with problematics of PTZ-camera re-calibration during movement. The objective of this work is to keep the camera in calibration mode from default status when the known positions of Vanishing Points are in the image. With their use during movement, which is changing with motion of the camera, their positions are kept with help of two implemented methods. The first method is based on the principle of homography, the second on the principle of cross ratio. The results show that both of these methods work especially for keeping the positions of First Vanishing Points. In the case of the Second Vanishing Points there appear various problems and the results are often quite inaccurate.

Body part tilt monitoring system
Bilík, Jan ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
The goal of my master thesis is to do hardware design and software debug of a battery-powered device, which is able to measure angle change relative to the starting position for three days. When tilting out of adjustable bounds, the device is able to alert via sound and vibrations. Additionally, it is able to save tilt data to its memory and then transmit them to the computer via USB.

Plan curved pedestrian bridge
Lachová, Alžběta ; Jurík,, Michal (referee) ; Koláček, Jan (advisor)
The subject of this master thesis is the elaboration of a study of a curved footbridge leading over the Svratka River. Two variants were created, from which a suspended structure was selected for subsequent modelling and assessment. The footbridge consists of a monolithic bridge deck made of prestressed concrete. The cross section of the bridge deck is designed as an asymmetrical box girder, suspended on one side by a pylon. The pylon is located on the inner side of the bridge deck at the junction of the apex and the centre of the circle and is anchored by hinges to the subgrade.
