Location Estimation of Objects in WiFi Communication Network
Kohoutek, Jan ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The purpose of the thesis is to design and physically implement a system for location of devices in a Wi-Fi based networks deployed in the interior of small and medium-sized enterprises. First of all, the attention is given to the survey of commonly available technologies suitable for determination of the object position. Then, based on these findings, architecture of a location system comprising an array of sensor nodes and central processing unit is proposed. In conclusion, the results are presented and the fulfillment of the requirements is evaluated.
Software Tool for Visual Specification of Laboratory Experiments Execution Flow
Truhlář, Jan ; Zbořil, František (referee) ; Šimek, Václav (advisor)
Aim of this work is to design and create a software tool, which will allow visual specification of laboratory experiments flow on device called GOLEM. This device was created by research group from Department of Chemical Drugs, University of Veterinary and Pharmaceutical Sciences Brno. This software was based on modern web technologies, tools for their design and implementation. The software created in this work offers ergonomic and the highly modular user interface which can be easily extended in case of upgrade. Main benefit of this work is providing research group with a new software tool which will help them perform experiments more effectively.

Mobile Application for Remote Measurement Support Using Sigfox Communication Network
Bulawa, David ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The purpose of this project is the implementation of a mobile application for the operation system Android.  The application supports remote metering via the Sigfox network and local metering via Bluetooth Low Energy. I implemented it natively in the Kotlin programming language using the Model-View-ViewModel design pattern. Measured values are collected remotely using the Sigfox REST API and locally using the Android Bluetooth library. The collected data are persisted in the local database on the mobile device. Then, the data is interpreted and visualized into graphs that the user can customize.  The created solution provides a possibility to acquire, monitor and visualize data from sensors, including their historical values. The application is easy to use, but also allows configuring data interpretation and supports several different incoming message formats.
Strategic Game with Uncertainity
Tulušák, Adrián ; Šimek, Václav (referee) ; Zbořil, František (advisor)
The thesis focuses on creating an autonomous functional system for the game Scotland Yard by using artificial intelligence methods for game theory and machine learning. The problem is solved by algorithm of game theory - Alpha Beta. There was an attempt to use machine learning, but it proved to be unsuccessful due to the large number of states for expansion and insufficient computational recourses. The solution using Alpha Beta algorithm was tested on human players and it proved the ability of artificial intelligence to fully compete against real players. The resulting system is functional, autonomous and capable of playing the game Scotland Yard on simplified game area. Based on these experiments, the thesis also introduces some improvements that could utilize machine learning and extend the existing solution.
Wireless Bicycle Speedometer
Ročkár, Martin ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Main goal of this bachelor thesis is practical design and implementation of a digital wireless cyclocomputer. This document can be divided into two parts, theoretical part which describes history of cyclocomputers, basic principle of cyclocomputer functions, overview of cyclocomputers on today's market, motion sensors and design of hardware. Second part is concerned about practical realisation and implementation of a wireless digital cyclocomputer.
Wireless Localization Module with Low-Power Firmware Based on RTOS
Lipka, Radim ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
This thesis focuses on the design and implementation of the wireless localization module, using UWB technology with emphases on low-power firmwre based on RTOS. Wireless localization is based on TDoA algorithm.  The resulting HW module is designed as a four layer PCB, based on MCU crf52832 (ARM Cortex M4) and UWB module DevaWave DW1000. Firmware is implemented using FreeRTOS with emphasis on low power consumption. For hardware implementation, Eagle CAD was used. Firmware is implemented in C and Assembly programming languages.
Quality Monitoring Device for Electrical Power Networks
Bartoň, Jan ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
The diploma thesis deals with the parameters of electricity quality. The aim of this work is to design and implement a prototype device that will allow remote measurement of power quality. The proposed system uses NB-IoT technology for data transmission. The system enables remote measurement of important parameters of electrical energy, such as the magnitude of the supply voltage or the frequency of the electric network. The device can measure electric current, average voltage values and detect dip / swell voltage events. The device reads a sampled electrical signal suitable for harmonic analysis. The device has started to meet the requirements for measuring device of class S according to EN 61000-3-40.
Embedded Control Unit for Instrumentation of Laboratory Appliance
Voda, Zbyšek ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Aim of this thesis is modular design of control system for Golem device, which is used for drug research. Several modules with specified controlled area were designed. They communicate using CAN bus and are controlled by Raspberry Pi computer. The thesis includes PCB design and control firmware for modules, backend application for Raspberry Pi, which provides application interface, and simple protocol used for communication between modules. Designed system was tested in simulated environment.
