Modeling and animation of biological structures
Matulík, Martin ; Bílek, Michal (referee) ; Maxa, Jiří (advisor)
Following work deals with subject matter of digital modelling and animation of biological structures. Software tools for computer generated images (CGI), well proven in common practice, are evaluated, as well as tools for specific activities, available inside chosen software environment. Among vast pool of modelling approaches are discussed tools suitable for creation and representation of selected structures, along with tools essential for their consequent animation. Possible rendering approaches and their parameters in relation to qualities of resulting computer-generated images are discussed as well. Above-mentioned approaches will be consequently utilized for modelling, physical simulation and animation of erythrocyte’s flow throughout blood vessel in following project. Resulting output of that work will be based on series of digital images, suitable for creating video-sequence containing abovementioned animation in end-user digestible form.

Analysis of supersonic flow in experimental chamber by insertion of pressure and temperature probes
Šabacká, Pavla ; Bílek, Michal (referee) ; Maxa, Jiří (advisor)
For the supersonic flow mode, which occurs in the internal flow behind the aperture separating two spaces with a large pressure drop, the critical flow is a characteristic phenomenon. In the case of critical flow behind the aperture, a supersonic flow area with reduced pressure ending with a shock wave with a step change in state variables is created. When diagnosing velocities, which are obtained from the values of static and total pressure, due to the changes caused by the shock wave passage, correction of the diagnostic quantities obtained by measuring by means of mathematical relations taking into account the physical phenomena is necessary.

Wireless communication between remote PLC and lab model
Bílek, Michal ; Šír, Michal (referee) ; Štohl, Radek (advisor)
The main goal of this bachelor thesis was to get familiarised with programmable devices from the Rockwell Automation company and with radio modems from the Satel company. The aim of the thesis was to control a model of a fractionating column situated in a distant laboratory. The device, designed to be controlled inside the lab, assessed the data which it received from the fractionating column model and sent the data by which it controlled the column. For wireless communication between the devices a radio modem Satel 3ASD was chosen. The thesis describes the visualisation and communication of the controlling of the fractionating column model. In the final phase the functionality of the designed visualization and communication was tested.
