Building Heating System Controller Using Zigbee
Mičulka, Lukáš ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This thesis is focused on the design and implementation of heating controller system of the model house. In terms of design is the emphasis on simplicity, efficiency and scalability. Implemented heating controller system includes a central controller unit and modules that are placed around the model house and can perform several functions - temperature measurement, control actuators or remote parts of the wireless link. This thesis describes the complete development from the initial system design through assembly of all elements of hardware, firmware implementations for each module type and a control program running in the control unit. It also describes the communication between system elements. Suitably chosen solution combines wired and wireless connections, depending on how it is ideal in terms of the model house. The whole system of functional prototypes was tested and the results were summarized in the conclusion.

GameBoy Advance Emulator for Mobile Platforms
Vilímek, Hynek ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
The GameBoy Advance console was released by Nintendo in 2001 and it has experienced phenomenal success during its existence. It used to control the majority of the market at one time and partly due to this it has become synonymous with portable gaming consoles. This popularity was gained especially thanks to the games developed for it. They have become so popular that even today there is a demand for them. These games, however, are not played on the original consoles but on today's mobile devices. And since current mobile devices are technologically very different from the console, it is necessary to run these games via an emulator.

Intelligent Access Terminal Using ESP32 Platform
Pomykal, Šimon ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to design cheap intelligent access control system based on esp32. This system is designed for use in family houses, flats, garages, gardens etc. The designed system is composed of access control terminal module which uses fingerprint reader to authenticate people and of camera modules which monitor the area of entry These modules are connected to cloud using AWS IoT Core. Another part of the system is a cloud application which evaluates data from the system. The acces control system is meant to be part of a home security system, but can be used independently to some extent.

Design of Sensor Modules for ZigBee Wireless Network
Tichý, Andrej ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The purpose of this study is to contribute to spreading of the global phenomenon IoT and to create a sensory network. In my study I focused on the development of active and passive modules using the IEEE802.15.4 standard based on the ZigBee protocol. When creating my modules I was using the micro-controller CC2530 by Texas Instruments having the processor platform 8051. To implement the communication firmware for sensory modules I used the Z-Stack 3.0 implementation. The main communicator uses the CC2530 micro-controller as ZigBee network preprocessor and miniPC raspberry pi as ZigBee application processor. As a part of this study I created an active module that enables to control the relay; an RGB led strap using the PWM modulation and also the electric current measurement using noninvasive sensors. I also created a passive module including sensors BME280, TSL2561 and DHT11 to measure the air pressure, temperature, humidity and light intensity. Furthermore I created an universal module that makes easier the creation of new prototypes. Not least I created all-purpose raspberry mini-module. The relevance of this study is given by creation of module prototypes using the ZigBee protocol. Special value within this study has the the mini-module for Raspberry Pi which can be used in various roles within the ZigBee topology.

Home Security and Monitoring System
Valach, Lukáš ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The thesis elaborates on an implementation of wireless home security system. The wireless communication utilizes IEEE 802.15.4 radios and ZigBee communication protocol. The beginning of the thesis provides specification of the intended system followed by an evaluation of usable energy harvesting solutions and later by consideration of single board computer systems suitable for implementation of the control node of the sensor network. The rest of the thesis describes design, implementation and testing of particular components of the security system. Conclusion evaluates the achieved goals and offers suggestions for future work. The end products of the thesis are physical devices implementing wireless sensor nodes, control unit of the security system as well as a graphical user interface for the system management.

Acceleration of Data Compression with Parallel Architectures
Juránek, Luboš ; Tříska, Vít (referee) ; Šimek, Václav (advisor)
This bachelor thesis deals with the use of parallel architectures, in particular the GPU, for acceleration of selected lossless compression algorithms, based on a statistical method, and transformations, which change the entropy of the input data to achieve better compression ratio. In this work there are in theory summarized general information about parallel architectures and programming options for them, mainly using NVIDIA CUDA and OpenCL.

Design and Analysis of Systems for Advanced Guarding and Securing Objects and Areas
Komínek, Petr ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This diploma thesis deals with design, realization and analysis of security and surveillance systems for buildings and spaces containing advanced components. One of the main design's parts is dedicated to intruder alarm system, access system, attendance and CCTV systems with the possibility of automatic motion tracking. Controlling and monitoring of particular subsystems is possible both locally and remotely from a computer via a web interface or by means of a software. The access to camera system from a mobile phone is also possible. IAS/ACS systems also enable controlling and transferring information about their state via SMS. The designed system was realized completely and its operating was demonstrated. The realization is described in detail including illustration of configuration of particular components. A security analysis and a possible future development of the project is summarized in the conclusion.
