Audio D/A converter with external control using microcontroller
Špaček, Jan ; Stifter,, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This diploma thesis deals with the design of a laboratory measurement tool with ADC converter for audio and low frequency signals. In the introduction part a theoretical background of the ADC and DAC conversions are outlined. In the next chapters the technical solution of the laboratory converter is presented, including DAC with integrated circuit AD1852 and completed with digital audio receiver CS8416. This circuit secures compatibility with external audio devices with digital interfaces, like SPDIF or AES3. The digital receiver and audio DAC are added with serial communication interface for setup of the most audio and input parameters. This setup is operated by external microcontroller ATmega32 and original firmware. The thesis contains block diagram and schematic layout of the laboratory converter, including complete technical documentation for the construction and design.

Design of pneumobil driven by pneumatic motor
Podhorský, Petr ; Robenek, Dětřich (referee) ; Nevrlý, Josef (advisor)
Master thesis deals with design of "student" pneumatic car equipped by pneumatic elements of a chosen firm. The introductory part is devoted to mapping the Hungarian competition. The idea of designing such vehicles comes from this competition. Next step is analysis of vehicles that are present in this competition. The main part describes the development of vehicle from the initial design, through analysis of main components, through to the production and presentation. The work contains a strain-stress analysis of the frame which is made by using the finite element method. The work ends with the conclusion which assesses the results.

Translation of C Expressions to DIMACS Format
Grim, Pavel ; Charvát, Lukáš (referee) ; Smrčka, Aleš (advisor)
This work focuses on proposition of transfer of the expressions entered in the C programming language into DIMACS format and creation of program in programming language C++ making this transfer. This work contains a description of the C programming language and its operators. It also contains a description of the conjunctive normal form and a description of the DIMACS format. Following is a proposal for a program for the transfer of expression in the C programming language to the DIMACS format and description of realization of program performing this transfer.

Color-to-Grayscale Conversions
Pospíšil, Petr ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
Grayscale pictures were never replaced by color ones and will probably never be, because they are indispensable in many areas. In this thesis was chosen three methods for color-to-gray conversion. These methods was implemented afterwards. Within this thesis was also made test set of 24 HDR pictures, which was together with existing set of 24 LDR pictures used to test and evaluate features of implemented methods. These methods were also compared from the point of accurancy and preference using questionnaire.

Continuous vertical conveyor for transport the goods
Zálešák, Martin ; Bukovský, Radim (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis deals with the existing of transportation unit products and designing of a better conceptual solution of continuous elevator with fixed section of a gravity and roller conveyor. This type of conveyor is specified mainly for the transport of boxed products from the lower floor to the another. The diploma thesis is substantiate by the proposal of assemblies machines. It includes a complete 3D design, engineering and functional solution that is supported by basic strength and the check calculations. The attachments consist of the drawings of the proposed facility.

Transformation of Equation Editor Expressions to LaTeX
Šimek, Jiří ; Jirák, Ota (referee) ; Křivka, Zbyněk (advisor)
The bachelor thesis deals with the problem of transformation of Equation editor expressions to LaTeX. It presents description of Equation editor expressions in Word 2007, it subsequently focuses on the syntax of particular expressions and it suggests the ways of their transformation into LaTeX. The grammar, which was used for the implementation of the converter, is designed on the basis of the syntax of expressions.
