Biometric fingerprint identification
Dašek, Filip ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
In biometrics we use distinctive physical features for identification and verification of identity. The most famous technique is identification by fingerprints. This technique use unique structure created by papillary lines for unambiguous identification. Thesis contains methods which were created throughout the years for analysis and adjustments of fingerprint. The algorithm is based on compairng two pairs of minitua and calculating transform matrix for correct alignment

Linux Keylogger
Pivarník, Jozef ; Hájek, Josef (referee) ; Procházka, Boris (advisor)
This bachelor's thesis collaborates on methods of logging key strokes in linux kernel in order to reveal secret passwords. Two methods are presented, both of which are useful for specific purpose. While the first one is effective in catching passwords typed in linux terminal environment, the other one intercepts every key stroke, even in a graphical user interface, and is designed to be working on the lowest level.

Custom Compiled Fedora
Blažek, Jan ; Rogalewicz, Adam (referee) ; Smrčka, Aleš (advisor)
This thesis is focused on design and implementation of toolchain for compilation and installation of RPM packages from SRPM packages in Fedora Linux distribution. Tools can be set up to modify compiler options and rpm macros. A tool for custom compilation of Linux kernel was also implemented. This tool builds the kernel with default options or according to configuration supplied by user. The toolchain was used to create customized distribution. Resulting distribution contains these tools for compilation and installation of additional software.

Production Comparison of High Voltage Winding of Dry Transformers
Mrajca, Miroslav ; Bulín, Tomáš (referee) ; Ondrůšek, Čestmír (advisor)
This bachelor thesis deals with the history, importance, usage, construction and principle of the operation of transformers. The thesis also focuses on the detailed description of the parts which the dry power transformer is composed from, as well as the description of their manufactory and following assembly into one unit. The thesis contains the comparison of different technologies of manufactory of higher voltage winding and magnetic circuit. The thesis contains a process of design of the dry transformer with an example of calculation. The output is a comparison of different high voltage winding technologies in terms of production costs and winding factor.

AVR microprocessor implementation on FPGA
Hájek, Radek ; Dvořák, Vojtěch (referee) ; Pristach, Marián (advisor)
This bachelor‘s thesis deals with FPGA implementation of Atmel AVR core described using VHDL language. Basic architecture concepts and processor addressing modes are summarized in this thesis. The core including several peripherals was designed to be compatible with ATtiny26 architecture and instruction set. The microprocessor was described in VHDL and verified in several types of tests.

RedirFS - Application on Data Compression
Podroužek, Jan ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
This thesis in its first part examines the problems of developing linux kernel modules, specifically modules implementig RedirFS filters. In the next part it considers different types of copression algorithms and the implementation specifics on the CryptoAPI framework in the linux kernel. Finally it describes the design and operation of the CompFLT module that implements a RedirFS compression filter. Benchmarks done using the CompFLT module are presented in the last section.

Linux-Based Drivers for Embedded Systems
Kopáček, Jaroslav ; Strnadel, Josef (referee) ; Dobai, Roland (advisor)
Issues of design and writing device drivers is wide-ranging and therefore in this thesis we focus on the design of drivers for devices with field-programmable gate array (FPGA). Compared to the application-specific integrated circuit processors, where functionality is immutable, it is necessary for each new FPGA configuration to write a new driver for the required behavior. This thesis deals with the analysis of requirements and possible solutions of designing and implementation of device drivers for embedded systems based on OS Linux and the possibility of development automation. This thesis includes the design and implementation a driver generator which can generate Linux-based drivers for embedded systems. The driver generator is modular so the final driver can contain only the required functionality and no unnecessary functionality. Designed driver generator has been tested on the task of controlling light-emitting diodes which are used for diagnostics of the embedded system.

History of Materials for Production of Cross-country skis
Ptáček, Ondřej ; Němec, Karel (referee) ; Molliková, Eva (advisor)
The present bachelor thesis is of a retrieval type. The first part deals with the development of cross-country skiing and the development of materials and technologies used in the production of cross-country skis from the mid-20th century to the present. It also explains important concepts in terms of design, shape and types of cross-country skis. Additionally, materials for cross-country ski poles are outlined and their differences are discussed. The second part refers to some of the materials used in the manufacture of cross-country skis, or cross-country ski poles. The emphasis is mainly laid on composite materials and matrices. The matrix in composites is reinforced using fibre or other type of filler.
