Design of desktop applications using the workflow library
Zeman, Kryštof ; Číka, Petr (referee) ; Lattenberg, Ivo (advisor)
The theoretical part of the thesis generally focuses on history and development of work- flow library, briefly describing most important features and options, which gives the reader basics needed to understand and orientation in the topic. In practical part of the thesis is detailly analized prime example, which is showing options, flexibility and advantages of connecting WF and WPF libraries. Primarily the thesis uses the most widely used model and shows how to pass information between workflow and WPF.

Modelling of mmWave Propagation Channel for Off-body Communication Scenarios
Zeman, Kryštof ; Vozňák, Miroslav (referee) ; Gaydamaka, Yulia (referee) ; Hošek, Jiří (advisor)
Předkládaná disertační práce je zaměřena na \uv{Modelování propagačního kanálu pro off-body komunikaci v oblasti milimetrových vln}. Navzdory pokrokům v rámci bezdrátových sítí v přímé blízkosti člověka stále systémy 5. generace postrádají dostatečnou šířku pásma a dostatečně nízkou odezvu. To je způsobeno neefektivním využíváním rádiového spektra. Tento nedostatek je potřeba co nejdříve odstranit a právě z tohoto důvodu je hlavním cílem této práce navrhnout vylepšený model rádiového kanálů pro off-body komunikaci. Úkolem tohoto modelu je umožnit uživatelům efektivněji a přesněji simulovat propagaci signálu v rámci daného prostředí. Navržený model je dále optimalizován a ověřen vůči nejnovějším měřením, získaným z literatury. Nakonec je tento model implementován do simulačního nástroje NS-3, pomocí kterého je následně využit k simulaci množství scénářů. Hlavním výstupem této práce je ověřený model přenosového kanálu pro off-body komunikaci v rámci milimetrových vln, společně s jeho implementací do simulačního nástroje NS-3, díky čemuž je dostupný pro širokou veřejnost.

Sensing Device based on Windows 10 IoT Core
Vaľuš, Dávid ; Zeman, Kryštof (referee) ; Hošek, Jiří (advisor)
This bachelor thesis focuses on installation of system Windows 10 IoT Core on microcomputer Raspberry Pi 2 and creating AllJoyn application for measuring temperature, humidity and brightness via bluetooth interface. In theoretics part technologies like M2M (Machine To Machine) and IoT (Internet of Things) are described, actuall trends and the future and AllJoyn platform. There is also a comparsion of operating systems available for Raspberry Pi 2. Practical part focuses on the installation of system Windows 10 IoT Core on Raspberry Pi 2 board. It also deals with verification of the functionality of the system via testing aplication for temperature measurement via SPI interface and bluetooth. In practical part we joined the AllJoyn network and via this network we shared data from a Bluetooth sensor.

Server application to process data from a MySQL database and their interpretation
Gardian, Ján ; Zeman, Kryštof (referee) ; Červenák, Rastislav (advisor)
Diploma thesis is about creating server application that process and interprets data from the database. Main aim of such application is able to process a large number of database requests in real-time environment. Provided database contains records of measuring download speed and quality of mobile connection via different radio technology from various providers. Those measured data are sent from users all around the world and amount of data collected is still growing. Therefore created server application can adapt to increasing size of database thanks to aggregation. This method of aggregation and use of index in database tables are further discussed in the theoretical part. Mainly putting indexes in tables produce significant acceleration of processing database requests. Final product of this thesis is an application that consist of three components: a server application running aggregation, website that interprets measured data and back-end interface providing measured data as well. Data at the website are presented in form of graphs for different countries and used radio technologies. Web address and user manual for finished applications are provided in the fourth chapter of diploma thesis. In the last part of thesis are performed various speed tests of programmed application that confirm the effectiveness of selected and described methods to accelerate work with the database.

Management and Monitoring System for Computer Lab
Kudláček, Marek ; Zeman, Kryštof (referee) ; Mašek, Pavel (advisor)
This master's thesis deals with a system for PC mass management and monitoring. There is a brief description of Puppet, Chef and Ansible, which are tools enabling this functionality. The overall system issues are solved by Ansible. This thesis also includes a script created for a classroom’s remote management according to a beforehand fixed assignment. The system enables remote installation and configuration of applications, creation of users, editing the files, update of the system and many more. A web application was created for this system. Through this application, the system can be controlled via web browser, both from local and public network. Practical examples of the issue dealt with is also part of the thesis.

Application for Wearables Running Apple WatchOS
Singh, Kevin ; Zeman, Kryštof (referee) ; Mašek, Pavel (advisor)
Bachelor work „Application for wearable electronics with Apple WatchOS system“ deals with theoretical analysis of M2M (Machine-to-Machine), H2H (Human-to-Human) and D2D (Device-to-Device) communication and wearable electronics. Later in the theoretical part, smart watch Apple Watch is described, which contains required WatchOS system. During compilation of this bachelor work were created two applications. One was made for iPhone and a second for Apple Watch. Both applications are able to show information about Internet connection and the user s location. The application for iPhone is also able to store data in the local and server s database.

Virtualization of ARM architecture and development of a universal control platform for embedded systems
Páleník, Luděk ; Mašek, Pavel (referee) ; Zeman, Kryštof (advisor)
Bachelor thesis "Virtualization of ARM architecture and development of a universal control platform for embedded systems" deals with theoretical analysis of IoT devices, M2M communications and virtualization techniques -- especially emulation of different processor architectures. The practical part is implementation of the modified emulated image for CM-T43 module from Texas Instruments manufacturer. QEMU emulation tool installed on Linux operating system is used for emulation. Another part of this work is to develop an application that allows reading and writing of data from / to each sensor based on a serial line (RS-232, RS-485) and Ethernet. The application is written in language C and uses the MODBUS protocol.

Audio Amplifier with Network Streaming and Sound Equalization
Liska, Matej ; Zeman, Kryštof (referee) ; Štůsek, Martin (advisor)
Diploma thesis contains the theory for the design and realization of a prototype audio amplifier device with the possibilities of digital or analog input content. It approach the features of D/A converter, analog filtering, volume control and amplification. Besides others, it describes the regulation of supply power voltages for individual active parts of device and approaches the software audio platform for acquisition and processing of audio data, including equalization. The thesis contains an general schematic design, created placement of individual components on board, including their table of descriptions and evaluation of the achieved results, including measured values and graphs.
