The Body as an Interface
Kučerák, Michal ; Fulka, Josef (advisor) ; Češka, Jakub (referee)
MK: Telo ako rozhranie bakalárska esej Abstract: This bachelor thesis discusses the topic of body in video games in philosophical perspective. The main issues are: What is happening with the body of player during the play? How does this "works"? The essay itself contains definition of game as well, definition of video game provided by Juul and roots of video game itself as cyber culture (Levy) and technical image (Flusser). It shows the history and present of video gaming. The question whether the body will or will not play important role in the future of gaming is being discussed in Hansen's, Virilio's and Deleuze and Guattari's definition of body itself. The essay claims there are two ways of playing the video games through our body: active playing and passive playing. Key words: video game, body, active/passive, visual semiotics

Property record based on RFID technology
Černý, Jakub ; Dydowicz,, Petr (referee) ; Kříž, Jiří (advisor)
This bachelor work focuses on the study of the modern technology of RFID tags and its application at Faculty of Business and Management in Brno. The main subject of this work is to use this technology as a replacement of barcode technology with the intention of raising processing speed, effectiveness and protection against stealing.

Design and Simulation of Single Phase Active Rectifier
Bareš, Jiří ; Huták, Petr (referee) ; Klíma, Bohumil (advisor)
This thesis deals with single-phase active rectifier, strategy of control and simulation of its model. In the beginning of this work a principle of rectifier is described along with transistor switching system, which has impact on shape of input current. Dimensioning of rectifier for assembling model and designing of control, including phase-locked loop and regulators follows. In the end assembled model and its simulation is described.

Active Compensation of Tool Deflection
Zarboch, Jaromír ; Marek, Jiří (referee) ; Březina, Tomáš (advisor)
This paper deals with design of tool deflection compensation system for milling spindle C1, provided by company TOSHULIN, a.s. A simplified simulation model of the spindle supplemented by compensatory elements was built by using programs ANSYS, MD ADAMS, Matlab/Simulink. As action elements there were use three piezoactuators each controled by PID controler. Efficiency of this compensation system was verified based on performed simulations.

The Active Bonnet Hinge
Galda, Michal ; Růžička, Bronislav (referee) ; Brandejs, Jan (advisor)
This thesis deals with designing the construction of an active bonnet hinge, tuning the kinematics and appropriate proportioning of individual parts of the hinge. The thesis consists of two main parts – the first part is an analysis of the current state of knowledge and the second part presents a designing the construction. The active hinge should serve as a safety element in automobiles to minimize consequences of head injury suffered during the collision of a pedestrian with an automobile.

Analysis of potential active damping for vehicles
Svoboda, Jakub ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
Diploma thesis deals with the issue of active and semi-active damping and its possible applications in the context of vehicles. The beginning of the document is focused on the actual state, major applications and patents in the field. As each of the individual ways of usage is relatively specific, the next part is aimed particularly at the damping unit of bicycle. Given the choice, real measurements and simulations were made in order to verify the applicability of such a device in practice.

Sensitivity analysis of frequency filters with current active elements
Kupčík, Petr ; Koton, Jaroslav (referee) ; Kubánek, David (advisor)
This bachelor´s thesis is about sensitivity analysis of frequency filters with current active elements. Includes theory of sensitivity analysis and sensitivity function. There are two second order multifunction frequency filters analysed. The first one is filter with Current Mirrors and Inverters (CMI). The second one is filter with Current Operational Amplifiers (COA). Conclusion is description how tolerances of passive and active elements affects frequency characteristics of filters and comparison of these filters in light of sensitivity. Next chapters are occupied by another two analyses: Parametric Sweep and Monte-Carlo. These analyses are applied on two fourth order frequency filters with Differential Input / Output Current Followers (DIOCF) and also on two previous second order filters (only low-pass filters). Parametric Sweep is applied on internal parameters of active filter elements (not in case COA). During Monte-Carlo analysis passive elements have tolerance 5% and active elements are considered ideal. Conclusion is description how tolerances of passive elements (Monte-Carlo) and parametres of active elements (Parametric Sweep) affects frequency characteristics of filters.

Machine Tool Spindle Units: Active Tool Deflection Compensation
Zarboch, Jaromír ; Vetiška, Jan (referee) ; Březina, Tomáš (advisor)
Cutting forces during milling process cause tool deflection. There are several methods for compensation of this deflection. This paper is focused on the active method of tool deflection compensation which angles adaptronic spindle by piezoactuators to compensate the tool deflection. For this method the simulation model was built in programe Matlab / Simulink. The effectiveness of this model was validated by search simulations.
