JSON Schema Maker
Fujaček, Martin ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
JSON Schema predstavuje spôsob určovania ako majú vyzerať dáta formátu JSON. Táto práca má za cieľ zjednodušiť definovanie schém pre existujúce dáta formátu JSON. Popisuje návrh a implementáciu jednostránkovej aplikácie pre generovanie JSON schém podľa vzoriek JSON dokumentov. Výstup aplikácie môže pomôcť užívateľom s tvorbou kostry schémy. Prínos tejto práce spočíva v možnosti generovania výslednej schémy nad viacerými vzorkami JSON dokumentov bez nutnosti opakovaného používania aplikácie a následného zlučovania jednotlivých schém do výslednej schémy. Okrem toho poskytuje automatickú validáciu pri manipulácii či už so vstupom, alebo schémou, pričom poskytuje dodatočné informácie o prípadných chybách.

Order Processing from the Information Systems View
Dostál, Jaroslav ; Mihalisko,, Marek (referee) ; Videcká, Zdeňka (advisor)
In the first part of bachelor’s thesis is described the firm, its position on a market and action internal and external effects on ongoing processes in the firm. Next is compiled theory of management, like hierarchy of controlling positions, or like effects modern controlling systems for the support of decision. Order processing is analyzed from the sections like customer service, material planning, production planning, production and store. Next is construction the chart of this order processing and described the most important software on those sections, e.g. SAP R/3 or IBM HOST, which are used for elaboration of orders. The worst problems on the sections are described in the next part and than are designed options for their correction. Proposed solution is: remove system IBM HOST and implementation a new module APO of the system SAP R/3 from SAP corporation. In the end are summarized benefits, which can firm reach by its implementation.

Git Reporting Tool
Nečas, Vojtěch ; Hruška, Martin (referee) ; Vojnar, Tomáš (advisor)
This bachelor thesis is about an implementation of the software tool dedicated for creation and visualization of statistical information files work. It also refers about Git version control system. System Git does not have any functions to display graphical statistics (graph or chart), therefore the output of the changes of the files is available in command line only. Such data, especially in a large amount of specific files, are not easy to analyze without using other existing statistic tools. There are couple of tools available which are capable of getting information of changes in Git, classify the statistics and display the results. The main disadvantage of such tools is a very long time needed to obtain the results. These tools support only very brief statistics and the user interface does not provide sufficient comfort either. The tool elaborated in this paper is offering more effective access to the changes information from Git using the saved data database. This database, compare to a single command line, is offering quick access to all information and timeline while there is only one time demanding operation - setting up the database. User-friendly interface is enabling an easy operation of the tool itself using window based interface. As a result there are various statistics (graphs and charts) which are user-editable. On the top of that the tool is equipped with an approximate estimation of the project work trends (mathematical-statistical method of the least squares).

The technological stage of the underground construction of the New Mill - Fatra
Wiesner, Jan ; Brandtner, Michal (referee) ; Kantová, Radka (advisor)
The content of this bachelor thesis is the technological stage of the rough substructure of the industrial building Nová Válcovna - Fatra. The work deals with the technological regulation for foundation structures, which will be drawn up control and test plan, time schedule, itemized budget. It also includes a coordination situation, a drawing of the construction site equipment, a design of the machine assembly, a drawing of the construction site equipment, and the safety of the technological stage. In addition, several schemes for the execution of individual structures and an energy performance certificate have been developed for this technological stage.

Active studio speakers
Bartoš, Adam ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
This bachelor's thesis deals with problematics of low frequency amplifiers in D class and their usage in active bi-amp speaker systems. It also deals with construction of so called band crossovers, made using digital signal processors (DSP) that are used as high and low pass filters, and with construction of speaker boxes itself. This work contains simulations of power supply, preamplifier with crossover and volume regulation and power amplifier in app PSpice and simulation of speakers in app Amplion. The draft of an overall diagram can be seen in block scheme and further in schematics of separate modules.

Frequency filters controlled via microprocessors
Bronec, David ; Kincl, Zdeněk (referee) ; Biolková, Viera (advisor)
This thesis is focused on the microprocessor-controlled frequency filter project. The main goal of the thesis is to present basic terms and principles of frequency filters and active frequency filters for cascading synthesis. Furthermore, the work contains information on digital potentiometers. The thesis includes circuit simulations and a project of connecting with a printed circuit board. The last chapter contains the results of the measurements.

Powering through USB Type-C Power Delivery technology
Golian, Igor ; Sklenář, Jaroslav (referee) ; Krajsa, Ondřej (advisor)
This thesis deals with fast charging using USB Type-C Power Delivery technology. The aim of the work was to compare individual technologies with USB-C Power Delivery technology. The necessity of the work was also to design and implement the device in the function of a source and appliance. The design of the printed circuit board itself was carried out in the EAGLE program. The work also too describes the design of the printed circuit board to the final device.

Implementation of printed circuit board with high-speed data lines
Čunderlík, Dávid ; Hanák, Pavel (referee) ; Krajsa, Ondřej (advisor)
This master’s thesis covers the design of PCBs with high-speed buses and signal paths. Theoretically describes the causes of problems associated with the design of these systems and their general solutions. Emphasis is placed on recommendations for system designs with DDR3 / 4 memories and PCIe interface. The work describes the recommendation for each critical point of the design and an example of these recommendations is designed PCB with ARM processor TI AM6526 on an 8-layer printed circuit board in the format "System on module" with a size of 80x60 \, mm. The connection of this "SoM" to the expansion boards is solved via a pair of DF40-100DS connectors and the "SoM" itself contains 4 memory modules DDR4 interface for Micro-SD cards, 16GB eMMC memory.
