RedirFS - Application on Directory Merging
Holášek, Petr ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
Main purpose of this work is to explore history and methods of directory unions, to make a proposal of design and finally to implement Linux kernel module that merges content of directories using RedirFS framework. We will discuss and solve related problems like namespace overlapping or underlying directories changes.

Rootkit for MS Windows
Trutman, Michal ; Tomec, Martin (referee) ; Procházka, Boris (advisor)
This bachelor's thesis deals with methods of attack on MS Windows operating system and maps techniques of resources hiding used by existing rootkits. The thesis consists of a theoretical and a practical part. The first part covers classification of the rootkits, introduces the structure of the system kernel and then describes various techniques of attacking the system. In the practical part is described implementation and testing of my own rootkit.

Porting of RedirFS on Other OS
Czerner, Lukáš ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
This thesis describes preparation for porting as well aw porting itself of RedirFS Linux kernel module to FreeBSD. Basic differences between Linux and FreeBSD kernels are described as well as differences in implementation of the Virtual Filesystem, crucial part for RedirFS. Further there are described possibilities and different approaches to implementation RedirFS functionality to FreeBSD. Then, the possibilities are evaluated and ideal approach is proposed. Next chapters introduces required functionality of the new module as well as its solutions. Then the implementation details are described so the reader can very well understand how the new module works and how the required functionality is implemented into the module.

Software for Microscope Image Processing and Analysis
Pavlišta, Libor ; Odstrčilík, Jan (referee) ; Čmiel, Vratislav (advisor)
This project informs about the basic image processing on grayscale and binary images. The project deals with analyzing the data obtained. Acquaints with terms such as morphology and image segmentation. Acquired knowledge is applied to create a program to complete the processing of microscopic images in LabView programming environment with subsequent analysis and plotting of results into image. For a better idea supporting data about operation in progress are continuous images.

Kernel module definition and networking server configuration for Linux operating system
Pecho, Ladislav ; Matocha, Tomáš (referee) ; Komosný, Dan (advisor)
The goal of my work is to create two computer labs lessons. The first one is a guide in writing a simple Linux kernel module, and in making a file inside the procfs filesystem. The content of the file can be decided as late as at the moment of reading. The second lesson describes the configuration of a server which allows a computer to boot over network. DHCP server is used with a TFTP server for file transfers which are both handled by the dnsmasq program. The example configuration will display a menu on the client station. It is possible to select to boot either a Linux kernel, floppy disk image, Linux network installer, diagnostic tool Memtest, or a text mode game Grub Invaders. The chosen bootloader is pxelinux from the syslinux project.

Automatic code processing for GNU/Linux cores
Doktor, Lukáš ; Horák, Karel (referee) ; Honec, Jozef (advisor)
Solves an automatic getting of profilation informations of the GNU/Linux's kernel. Solution is based on an interconnection of existing project gcov-kernel, Red Hat Test System and optional test suit. Red Hat Test system helps with an installation and setting up an computer. Modificated kernel by gcov-kernel provides profillations data of the running system. After all job is done, those informations are proceed into human readable form.

Linux port for DaVinci DSP family
Šujak, Marek ; Petyovský, Petr (referee) ; Valach, Soběslav (advisor)
The main subject of this thesis is implementation of operating system based on Linux kernel. The thesis demonstrates ARM architecture and the programming model of this architecture very briefly. Then it explains initialization process of most significant peripherals including serial interfaces and memory controllers and describes booting process form NAND, NOR memory and UART interface. At the end it shows compiling procedures necessary for building u-boot and kernel.

Experimental testing of bus peripherals on single-board computer Beagleboard.
Hladík, René ; Zuth, Daniel (referee) ; Věchet, Stanislav (advisor)
This bachelor’s thesis obtains a kind and possibility of communication, which single board computer offers. Check range of communications using mobile robotics and summary for this system. The result of this work provides a configuration all peripherals for Beagleboard system using. The introductory part of work is focuses on the definition and summary single board computer systems. Description main differences single board systems. Next point is competition and summary single board computers from the world's leading manufacturers and hardware differences. The next part is making complete description and summary of using single board computer Beagleboard xm Rev C. Practical realization obtains the most important interface of communication, which we can use in case of prototypes mobile systems. Realization of USB camera, multifunctional interface GPIO, serial communication of CMUcam3 camera module and in conclusion I2C communication using GPIO SRF08 ultrasonic sensor. Demonstration of Beagleboard system diversity, what can use all users of embedding systems in mobile robotics. Modern mobile robotics systems are complex analog and digital devices like different kind of sensors, sensing elements, cams and else. Bachelor work describe basic configuration some possibility communication with using cameras, sensors and systems elements.

Term Structure of Interest Rates: Macro-Finance Approach
Štork, Zbyněk ; Mandel, Martin (advisor) ; Kodera, Jan (referee) ; Vejmělek, Jan (referee)
Thesis focus on derivation of macro-finance model for analysis of yield curve and its dynamics using macroeconomic factors. Underlying model is based on basic Dynamic Stochastic General Equilibrium DSGE approach that stems from Real Business Cycle theory and New Keynesian Macroeconomics. The model includes four main building blocks: households, firms, government and central bank. Log-linearized solution of the model serves as an input for derivation of yield curve and its main determinants -- pricing kernel, price of risk and affine term structure of interest rates -- based on no-arbitrage assumption. The Thesis shows a possible way of consistent derivation of structural macro-finance model, with reasonable computational burden that allows for time varying term premia. A simple VAR model, widely used in macro-finance literature, serves as a benchmark. The paper also presents a brief comparison and shows an ability of both models to fit an average yield curve observed from the data. Lastly, the importance of term structure analysis is demonstrated using case of Central Bank deciding about policy rate and Government conducting debt management.
