The master work is focused on the design and implementation of two parts of the system for measuring temperature and relative humidity. The system for measuring temperature and relative humidity consists of a network of wireless sensors, a ISM/Wifi converter and application which will collect, analyze and archive data. The design and implementation of ISM/Wifi converter as well as the design and implementation of application are described in this work. ISM/Wifi converter will be able to communicate with the network of wireless sensors through ISM/Wifi protocol and end device (the device with Android operating system) by means of IEEE 802.11 protocol. The application will be able to evaluate, to save and to present user the received data very clearly.

The theme of this thesis is the design and optimization of algorithms for controlling stepper motors with feedback by measuring the BEMF. The emphasis was on self-management stepper motor current depending on the load. To verify the algorithm was designed and built sample devices with integrated circuit NCV70514 from ON Semiconductor. The result is a sample device, the control program and algorithm to control a stepper motor.

První část práce je zaměřena na měření QT intervalu. QT interval může být použit k hodnocení kardiovaskulárního zdraví pacientů a detekovat potenciální abnormality. QT interval je měřen od začátku QRS komplexu až po konec T vlny. Nicméně, měření konce T vlny je často vysoce subjektivní a jeho verifikace je obtížná. Představujeme dvě metody měření QT intervalu - vlnkovou a šablonovou metodu. Metody byly porovnány mezi sebou a testovány na QT databázi. Druhá část práce je zaměřena na modelování arytmických signálů McSharryho modelem následována klasifikací s použitím umělých neuronových sítí. Metoda používá předzpracování signálů lineární aproximací a shlukování lineárních segmentů pro stanovení počátečních parametrů McSharryho modelu. Byly použity EKG signály standardní MIT/BIH Arrhythmia Databáze. Modelování bylo testováno na celé databázi a svodu MLII (modifikovaný svod II). Všechny signály mohou být modelovány 10 Gaussovými funkcemi bez významného zkreslení. Třetí část práce představuje klasifikaci EKG do dvou tříd. Předčasné komorové kontrakce (PVC) mají vysoký význam při hodnocení a predikci život ohrožujících ventrikulárních arytmií. Představujeme algoritmus pro detekci předčasných komorových kontrakcí s použitím McSharryho modelu a neuronových sítí. Signály modelované 30 Gaussovými parametry byly předloženy na vstup umělé neuronové sítě. Použitý vícevrstvý perceptron dosáhl klasifikační úspěšnosti 93,10% pro předčasné komorové kontrakce (PVC) a 96,43% pro normální stahy.

This diploma thesis is concerned with machine identification and verification of speaker, it's theory and applications. It evaluates existing implementation of the subject by the Speech@FIT group. It also considers plugins for the Skype program. Then a functioning plugin is proposed which makes possible identification of the speaker. It is implemented and evaluated here. Towards the end of this thesis suggestions of future development are presented.

This master's project focuses on basic techniques of creating shadows in 3D computer graphics. Two basic techniques are compared. Those are shadow maps and shadow volumes. Another technique combining previouse two is proposed.

Coloured Petri nets (CPN) are an extension of a standard place-transition Petri nets (P/T PN). Every token and place have its type (and eventually a value) and various inscriptions can be inserted into the net. CPN excel with great readibility and expresivity. At the same time, they carry a well-defined formal basis, which eases its computer simulation and allows limited verification of certain attributes to be performed. Motivation for doing this project is the simple fact that currently only one public software tool is available for CPN creation and simulation - CPNTools developed on the Aarhus university. The program, however, is quite complicated and hard to handle for an unexperienced user. The goal is to research capabilities and properties of both CPNs and CPNTools and on this basis design and implement a didactic application with swift and intuitive interface that helps users without deeper theoretical insight to get a grasp of the problematics.

This thesis describes the design and implementation of an client-server application. This application is used to remote access to models of systems, which are saved on the server. Application also provides editation of the models and their simulation. In the thesis there is a design of Communication Protocol between the client and server too. For the implementation of the client and prototype of the server was used Qt library. Server is realized as a part of existing simulation core (SmallDEVS), which is implemented by Smalltalk.

The aim of work is conversion of a photographed Braille into ordinary text. On the beginning, there are described Braille specification and principles. In the next part are mentioned types of sensors for taking photos. The main part describes phases of image processing and their implementation in C++. At the end, there are listed possibilities of future development.

The work contains presentation of the Geocaching game, mainly from the view of an information system. It contains study of existing applications with their advantages and disadvantages. There is a specification of new application, that should solve major disadvantages of existing products in second part of the work. Design of such application, that meets the requirements, follows. The application is implemented, which is described in following chapters, with the aim to target specific problems that were solved during the implementation. There is summary and future plans cotained in the closing chapter.

The purpose of this thesis is to introduce a reader with existed commercial applications and control the FITkit using QDevKit. The main goal of the thesis is proposed and implemeted modul for application QDevKit which makes easy proposal and progress applications for platform FITkit.
