Data Concentrator for Smart Grids
Franek, Lešek ; Beneš, Bedřich (referee) ; Kučera, Pavel (advisor)
The goal is to design data concentrator for Smart Grids. Data Concentrator provides the interface between the server systems of distribution companies and end devices, which are electricity meters, water meters, gas meters and other equipment. There are hardware and software design solutions and there is also discussed creating its own distribution of Linux.

Design and implementation of a universal data logger
Vokál, Tomáš ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
Subject of this thesis is to design universal datalogger while using .NET Micro Framewrok. The design was tested on a developing kit EMX produced by GHI Electronics. At the beginning a problematic of .NET Micro Framework is introduced to a reader. After that architecture of project and mechanism of controlling device are described.

Lightweight cryptography for embedded devices
Nekuža, Karel ; Fujdiak, Radek (referee) ; Martinásek, Zdeněk (advisor)
This bachelor thesis focuses on lightweight cryptography. The main focus is on block ciphers PRESENT and LBLOCK and hash function PHOTON. The theoretical basis of cryptographic primitives are presented with devices which are commonly used for them, cryptanalysis attacks and their success rate. The primitives are implemented on microcontroller separately and in cryptographic protocol. There was measured time and usage of memories of the implementations. The results were used for comparison of ciphers, hash function and selection of two versions of the protocol for testing. Each version was tested and compared to the other.

Multichannel Audio Signal Transmission Over Local Area Network
Kotouček, Filip ; Frenštátský, Petr (referee) ; Schimmel, Jiří (advisor)
This thesis deals with design and implementation of multi-channel audio signal streaming via local network. The aim was to choose suitable processor for the transmission of up to 32 channels of audio signal, which will be used for implementation. Also the low-latency ASIO driver was studied and was used to provide timestamps for synchronization. The transmission protocol was designed for signaling and for the real time stream. The actual transmission is provided by TCP protocol. In conclusion, I created the application for development board with choosen MCU. Finally whole solution was tested with real data.

Measuring of Electricity Consumption Utilizing Current Transformer and Arduino Platform
Pokorný, Rostislav ; Pokorný, Jiří (referee) ; Štůsek, Martin (advisor)
The aim of this bachelor thesis is implementation of non-invasive platform for measuring the consumption and production of electrical power. Developed device enables visualization of measured data on display. Electric current is measured by non-invasive current sensor equipped with split core made of ferrite. Measured data are processed on single board microcomputer called Arduino. The device enables wireless communication with a server platform that allows visualization of measured data in a simple graphical user interface based on the ThingSpeak platform. Created device can measure consumption or production of electrical power on appliance with maximum current up to 30 A without need of any changes in electric circuit.

Autonomous generator of test scripts
Horký, Stanislav ; Šimek, Václav (referee) ; Kolouch, Jaromír (advisor)
The subject of this master thesis are state machines and their testing. To this purpose, an application is described, which is able to test these state machines autonomously. Application have two parts, first generator and editor of data is built and second part is testing procedure, which is able to test state machines in question and to give corresponding test report.

The Progress run-time architecture
Pop, Tomáš
This thesis is a part of a bigger research vision called Progress which aims at providing component based techniques for the development of real-time embedded systems. Progress introduces the concept of a virtual node in order to increase the effectiveness of constructed systems and improve hardware abstraction. The thesis starts research of the runtime structures of the Progress component model. The thesis aims at identifying necessary questions about the runtime internal structure of virtual nodes and about the supporting mechanisms needed to run virtual nodes on destination hardware. A part of this thesis is also a sample implementation of the virtual node runtime environment covering local and Ethernet communication, event driven and timer driven tasks, and multiple computational nodes.
