A system for orders management in a restaurant
Vašina, Martin ; Hnětynka, Petr (advisor) ; Kofroň, Jan (referee)
The work is about the implementation of a system for orders management in a re- staurant, and is focused primarily on companies such as teahouse/cafe, ie facilities that are not divided into kitchen and bar, but have only one preparation room. The system, which enables fast and clear registration of orders and sales, helps to keep track of the company's finances and customer requirements. In addition, a suitable system is the key to better business services. There are already many order management softwares on the market, but due to the great variability of the properties of these systems, it is difficult to find just one that will meet the exact requirements of the company. Within this work was designed and implemented a system Orsy. The work was created for requirements of a specific tea house, where it is now used with satisfaction. In addition, the system contributes to innovation in the area of information systems for restaurants. 1

DiaSynth - Diagram Audio Synthesizer and Analyser
Strýček, Radek ; Kofroň, Jan (advisor) ; Ježek, Pavel (referee)
The main goal of this bachelor's thesis was to create user friendly audio software with graphical user interface. The program contains analyser, audio player in the style of Audacity and sound synthesizer, which is using diagrams to generate audio. Diagram consists of wave generators, operators and connections between them. The result of this work is functional program written in Java programming language. On top of that each part of program can be extended by plugins. To be more specific, it means that there is possibility for user to write own audio analysis algorithms for analyser, own operations for modification of audio tracks loaded in audio player and in case of synthesizer, it means that the user can implement own operators and generators and use them in diagram for sound synthesis. 1

Use of legacy and wireless protocols in modern IoT
Hraško, Andrej ; Bureš, Tomáš (advisor) ; Kofroň, Jan (referee)
Use of legacy and wireless protocols in modern IoT The main goals of this work is implementation of an extension into Inthouse system which will allow remote control of widespread Modbus-enabled devices and creation of an in-house-made simple controller controllable via Bluetooth using simplified JSON RPC protocol and addition of its control support into Inthouse. The next step is to summarize each implementation focusing on its technical complexity and a business potential. This work uncovers interesting details from the implementation and explain causes why such implementation was used in a commercial environment.

Application of Genetic Algorithms and Data Mining in Noise-based Testing of Concurrent Software
Šimková, Hana ; Kofroň, Jan (referee) ; Lourenco, Joao (referee) ; Vojnar, Tomáš (advisor)
Tato práce navrhuje zlepšení výkonu testování programů použitím technik dolování z dat a genetických algoritmů při testování paralelních programů. Paralelní programování se v posledních letech stává velmi populárním i přesto, že toto programování je mnohem náročnějsí než jednodušší sekvenční a proto jeho zvýšené používání vede k podstatně vyššímu počtu chyb. Tyto chyby se vyskytují v důsledku chyb v synchronizaci jednotlivých procesů programu. Nalezení takových chyb tradičním způsobem je složité a navíc opakované spouštění těchto testů ve stejném prostředí typicky vede pouze k prohledávání stejných prokládání. V práci se využívá metody vstřikování šumu, která vystresuje program tak, že se mohou objevit některá nová chování. Pro účinnost této metody je nutné zvolit vhodné heuristiky a též i hodnoty jejich parametrů, což není snadné. V práci se využívá metod dolování z dat, genetických algoritmů a jejich kombinace pro nalezení těchto heuristik a hodnot parametrů. V práci je vedle výsledků výzkumu uveden stručný přehled dalších Technik testování paralelních programů.
