Electrical installations in apartment building
Novotný, Jan ; Formánek, Marian (referee) ; Doležalová, Jana (advisor)
This bachelor's thesis deals with electrical wiring in apartment building. The aim is to describe the types of distribution networks, implementation possibilities of service lines, describe the individual parts of the wiring in the building and the principles of their implementation. Further describe basic electrical materials and to explain the design of artificial lighting. In the practical part the information applied to a particular apartment building, together with the calculation of the estimated annual energy consumption of flats. For the apartment building project is created in the form of engineering report and drawings.

A fuse heating measurement using IR camera
Belák, Michal ; Valenta, Jiří (referee) ; Aubrecht, Vladimír (advisor)
Bachelor's thesis deals with various principles of contactless temperature measuring and comparison of these principles. Different kinds of detectors, which are used in pyrometers and thermovision systems are presented, together with description of various kinds of the contactless thermometers, their division according to many different criteria. Next it is intended on the description of thermovision exploitation in different areas of practice. An example of practical fuse heating measuring and its analysis is also presented.

Current distribution and heat losses in the low voltage circuit breakers
Musil, Pavel ; Janda, Marcel (referee) ; Makki, Zbyněk (advisor)
The work is focused on the calculation of decomposing the current and the thermal loss in circuit breakers of low voltage. In the work´s first half, there is a summary of the most frequently used circuit breaker elements with a focus on their constructional layout. The biggest attention is devoted to the circuit breaker marked LPN-16B by the company OEZ. A model of the under current trajectory of this specific element is created in a program Inventor on which the following calculation of decomposing the current and thermal loss was accomplished in a program Ansys. The obtained results are assessed in the conclusion of this work.

A File System Implementing Storage for Gentoo Portage Based on a Relational Database
Štulpa, Adam ; Mlích, Jozef (referee) ; Rychlý, Marek (advisor)
The thesis deals with implementation of a program which can, through the use of FUSE library, make data accessible in the relational database like the classical Gentoo Portage storage. First, the reader of the thesis becomes familiar with FUSE library itself. After that, the new data model is built based on the analysis of the Portage structure. The new model emphasizes especially dependencies of packages. The key implementation issues are also described in the next part. Finally, the thesis assesses outcomes achieved including comparison with standard Portage implementation and classical file system. The other possibilities of the project development are considered as well.

Bootloader for Sci-Trace
Novák, Lukáš ; Novotný, Jan (referee) ; Šteffan, Pavel (advisor)
In this thesis analyze in detail issue Bootloader for microcontrollers AVR and made proposal for implementation to the device Sci-Trace. Modification electronics part deal with patch board, where used connect between others module and control board. Control Board handle with computer and individually module. Example others module are control optics or control stepper motors. From user interface is resolve choice information display for show temperature inside the device. From mechanical part is resolve store electronic part to the rack section. From programming part is create firmware for control board and others module. For users operation is create program for operation system for upgrade application firmware to microcontroller.

Design the Transformer Station for the Outgoing Power of Cogeneration Unit
Pastorek, Jaroslav ; Procházka, Aleš (referee) ; Orságová, Jaroslava (advisor)
The thesis deals with the design of a transformer station for the outgoing power of cogeneration unit with an electric capacity of up to 1 MW. The thesis describes the design procedure of individual devices such as a transformer with a nominal ratio 22/0,4 kV, high voltage switchgears and low voltage switchgears. With the proper selection of the transformer, along with the technical parameters, the economic benefits that come from its purchasing and operating costs with the transformer operation are also considered. Based on this, the economic comparison of selected types of oil transformers during 20 years is also developed. Another part of the thesis deals with HV and LV switchgears, which are dimensioned according to shortcircuit conditions in the transformer station. In conclusion this work deals with the grounding of a transformer station and design protection in accordance PPDS.

Design of electrical installations in industrial buildings
Cabal, Jan ; Bátora, Branislav (referee) ; Toman, Petr (advisor)
The thesis deals with planning and proportioning of electrical installations within industrial objects. The theoretical part of the thesis looks into electrical installation planning and proportioning for all kinds of buildings. Basic terms related to projecting, project requirements, as well as the requirements on the designer, project documentation composition, and project documentation grades, are descibed. Furthermore, the text covers implementations of protection against electrical injuries, related legislative regulations and requirements, and finishes with the issues of electrical installations proportioning and protection. The practical part of the thesis contains a design of electrical installations for an industrial object involving high power wiring for a mechanical – technological part of the Zaječí water treatment plant. In addition to wiring proportioning and protection, the design involves a technical report, layout drawing and distributor RM1 plan.

Virtual Filesystem to Access Contents of Archive Files
Samek, Michal ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This bachelors's thesis describes design and implementation of a console application, which could be used for creation of virtual filesystems from archive files. These virtual filesystems are managed by the means of the FUSE library. Application supports several types of archive files, for some of them even write support is implemented. Support for additional types could be easily integrated via designed interface.
