Wireless temperature sensor with high temperature warning indicator
Dvořák, Petr ; Petržela, Jiří (referee) ; Hruboš, Zdeněk (advisor)
This thesis deals with a proposal of a wireless temperature-sensitive element at high temperature. It analyses some different variants of the temperature sensors. Furthermore, the thesis describes the Industry Science Medical (ISM) bands, in which it will be possible to communicate with the wireless communication modules. These wireless modules are discussed and described. By the devices „the transmitter and the receiver" it is focused on the communication of the microcontroller Atmel with the wireless modules, with the temperature sensors, microswitches on the control and display unit (LCD).

The effect of the blue light on the human body
Dvořák, Petr ; Krbal, Michal (referee) ; Štěpánek, Jaroslav (advisor)
This thesis explains the term „blue light“. It deals with the sources of blue light and the effects of this type of electromagnetic radiance on human body. The focus is concentrate especially on problems, which are evocated of blue light. The biggest danger is the desynchronization of circadian rhythm and photochemical damage of retina – photoretinitis („blue light hazard“). The basic principles of biological processes and the visual system are described here. These processes are controlled by properties of incident light onto the retina of eye. The basic information about artificial sources of blue light commonly used in households and in industry are mentioned in the second half of work. These light sources were measured and elaborated. The electromagnetic spectrums of sources are portrayed and there is a comparison of sources due circadian effect too.

Frequency analysis with using optical system
Chlebounová, Klára ; Dvořák, Petr (referee) ; Jebáček, Ivo (advisor)
The goal of this thesis is to create a methodology for measuring vibration on the aircraft construction with using optical system and perform basic frequency analysis. Work shortly discusses the theoretical foundations of aeroelastic phenomenon and methods of solving its own deflection shapes and frequencies. In the practical part is measurement methodology designed for simple vibration of clamped rods and then is applied to a frequency analysis of the wing.

Google Gadgets in Ext JS Environment
Dvořák, Petr ; Schmidt, Marek (referee) ; Dytrych, Jaroslav (advisor)
This thesis aims to analyse the Google Gadgets platform and an existing system of a page layout manager of the KiWi project. It provides a brief description of both platforms and focuses on a design and an implementation of the Google Gadgets support inside the page layout manager. Finally it compares the original with the modified solution in terms of page loading speed.

ITIL Simulator
Dvořák, Petr ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This master's thesis presents analysis, design and implementation of an information system for supporting studying and practicing of selected methods described by Information Technology Infrastructure Library (ITIL) with focus on service design and service operation. In the form of a web application the thesis presents an uncommon approach to e-learning system development by extending the standard lecture part by game elements and interactive scenarios. Developed system allows creators to define services and tasks, such as incidents and problems caused by their operation, and evaluate reactions of responsible users. The application can be used by IT administrators or Service Desk managers to train new IT engineers or Service Desk operators.

Network Application Chess Learning
Dvořák, Petr ; Rozman, Jaroslav (referee) ; Zbořil, František (advisor)
The work deals with creating of application for teaching chess. Teaching methods include not only play against the computer, but also a network play against the player or computer. It is also created the support to use chess diagrams. The program support existing playing games in standard PGN format. A chess engine is responsible for analysis of these games and it communicates via standard Win / XBoard. The Chess engine generates alternative moves in a given position and provides the player to think about. The application also supports standard FEN. In the opening chapters of this work are discussed used tools, the basics of chess and more detail existing types of chess notation. In other parts of the work I analyze an existing individual chess standards, theirs design and theirs implementation in my program. In the rest of the work I describe designed and implemented parts of the program, such as its graphic design and supporting side panels. In the last chapter I describe the server that connects all the current players.

Study of elektrode materials based on manganese dioxide
Kos, Lukáš ; Dvořák, Petr (referee) ; Novák, Vítězslav (advisor)
This work deals with the production and use of catalytic materials in fuel cells. The basic focus of work is the production of samples of catalytic materials based on manganese dioxide-enriched mixtures of different dopants. Samples subsequently made to measure, compare with other samples and determine whether the samples are enriched with dopants better than samples without dopant. According to information received, then determine whether they are suitable for use in fuel cells.
