GPS for Teaching HW/SW Platform
Pajgrt, Ondřej ; Bidlo, Michal (referee) ; Fučík, Otto (advisor)
The work deals with a connection between HW/SW platform FITkit and GPS device. Introduces GPS systems from theoretical and practical view desribes FITkit teaching platform and its common use and shows in detail the connection of those two systems into a cooperative unit. Work also analyses communication interfaces and protocols used for that connection. Finally it provides a description of tho whole system data flow from the very beginning in GPS unit to the final displaying on the screen and description of implementation and application usage.

System for Virtual Server Administration
Karban, David ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
There is coming trend of virtualization on modern computers. One computer may act like host for several guest virtualized computers. This has many advantages, like for kernel development, software testing, virus behaviour testing, saving HW resources. On the other hand, complexity of computer maintenance is growing too. This bachelor thesis describes a system, that can be used for management of many virtual servers and lower the manageability overhead. This work will create a generic control interface for virtualized computers. Interface will be adaptable and extendible. The development of this system is described from specification through analysis to concept and implementation of application.

An Application Utilizing esmska Plugins for Sending SMS Messages via Web Gateways
Marton, Dominik ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This thesis describes the design and implementation of a console application, that utilizes esmska JavaScript modules to enable sending SMS messages from inside of user scripts via web gateways without CAPTCHA security plugin, and of a web service with REST interface making this application accessible remotely. Both are primarily made with the purpose of running on network devices with OpenWrt operating system while trying to minimise memory consumption. The whole solution is written in C with the help of libcurl library, embedded JavaScript interpreter Duktape and standard C library uClibc.

Arithmetic Circuit Generator
Bolješik, Michal ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
The goal of this thesis is to design and implement a tool that would be able to generate a description of various types of arithmetic circuits, such as adders and multipliers, that are involved in more complex systems (filters, transformations, etc.). The first part of the thesis deals with analysis of different types of adders and multipliers on either theoretical or practical level. In the second part there is a description of the design and implementation of the tool created in Python language. On base of parameters, the tool is able to generate hierarchical or flattened description of various circuits in formats aimed for visualization, simulation and validation. In the end, the tool is used to compare different designs of adders and multipliers.

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.

Time-Based Account Policies in FreeIPA
Láznička, Stanislav ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
Tato práce se zabývá běžnými problémy časových politik, které jsou využívány v rámci procesu přihlašování uživatelů. Jsou rozebrána řešení v některých jiných současných systémech. Dále je čtenáři představen projekt pro správu identit FreeIPA, autor se zaměřuje hlavně na správu uživatelů a politiky pro jejich autorizaci. Je také představen projekt SSSD se zaměřením na jeho propojení se systémem FreeIPA. Po vytvoření návrhu řešení problému časových politik je tento návrh implementován do systémů FreeIPA a SSSD.

A frequency inverter based on Texas Instruments DSP
Vašíček, Adam ; Macho, Tomáš (referee) ; Valach, Soběslav (advisor)
This bachelor thesis is focused on control algorithms optimization, especially using the Texas Instruments c2000 digital signal controllers family. The first part roughly describes an AC induction motor controlling and regulation techniques. Later on the control software optimization basics are covered. Particular attention is payed for trigonometric functions which are mandatory for such software. Next part shows practical use of the previously described optimization techniques using an example of the scalar frequency inverter control even going down to the assembly instructions level. At the end the results themselves as well as facing the invested price of optimization are discussed.

Meassuring system for building constructions
Vladař, Martin ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with the measurement of physical quantities in building using decentralized system for data collecting. The system consists of Raspberry Pi as a master device of the system. There are three branches connected to this master device. Each branch consists of up to 32 modules for data-concentration from sensors of physical quantities. The Raspberry Pi has implemented web interface for displaying measured values and system administration.
