HelenOS VFS-FUSE connector
Bouška, Zdeněk ; Děcký, Martin (advisor) ; Kofroň, Jan (referee)
This master thesis deals with the implementation of a connector between FUSE file system drivers and HelenOS native VFS interface. The thesis first describes the way of finding the best solution and the potential possibilities. The low level layer solution is described as the best one. Further the thesis describes the real implementation of the connector. As the implementation of the connector was successful the thesis then describes in detail the parts of the fully functional solution in real-life HelenOS system. With this solution in place almost no changes are necessary to be done neither in FUSE nor in Helenos VFS. The connector implementation is demonstrated on a real-life FUSE file system exFAT ported to HelenOS. Powered by TCPDF (www.tcpdf.org)

HelenOS VFS-FUSE connector
Bouška, Zdeněk ; Děcký, Martin (advisor) ; Yaghob, Jakub (referee)
This master thesis deals with the implementation of a connector between FUSE filelesystem drivers and HelenOS native VFS interface. The thesis first describes the way of finding the best solution and the potential possibilities. The low level layer solution is described as the best. Then the concern is focused on the real implementation of the connector. The implementation was successful, so the thesis describes in detail the parts of the fully functional solution in real-life HelenOS system. The solution enables almost no need of changes to be made in both FUSE and Helenos VFS. The connector implementation is demonstrated on a real-life FUSE filesystem Exfat ported to HelenOS.

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.

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.

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.

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.

A File System Implementing Storage for Gentoo Portage Based on a Relational Database
Štulpa, Adam ; Weiss, Petr (referee) ; Rychlý, Marek (advisor)
The thesis deals with an implementation of a program, which can make the data in relational database available as the standard storage Gentoo Portage with the assistance of FUSE library. The reader is initially familiarised with its structure. There is an analysis of the requirements on the program and the database described in the work. Furthermore, their proposal is given and in the penultimate chapter, there is described the implementation of the program. In the conclusion, there are all the outcomes evaluated including the comparison with the standard file system and further development possibilities of the project are also described.

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.

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.

A Hidden GNU/Linux File System
Pavlásek, Martin ; Smrčka, Aleš (referee) ; Lengál, Ondřej (advisor)
Some sensitive data need such a way of hiding that hides not only the content of the data but its preserve itself. The goal of this Bachelor's thesis is to create a file system that enables hiding of files with sensitive data to other files. This text contains an overview of principles used in current file systems and a description of the structure and use of the FUSE technology. Further, the work describes the design of a filesystem that hides files into ID3 tags of MP3 music files and it's implementation in C++. The created filesystem is experimentally assessed and evaluated.
