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.

Chess Program with Various Chess Variations with Various Initial Arrangement
Dvořák, Pavel ; Žák, Jakub (referee) ; Rozman, Jaroslav (advisor)
This thesis focuses on describing required components in the process of creation of modern chess application. Goal is to create chess program with several chess variations using structures and algorithms based on professional chess programs. Thesis describes principles of chessboard representation and various factors of chessboard state evaluation used in classic chess and implemented variants. Finally thesis describes game-tree search algorithms and enhancements and compares their effect.

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.

Content Based Photo Search
Dvořák, Pavel ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This thesis covers design and practical realization of a tool for quick search in large image databases, containing from tens to hundreds of thousands photos, based on image similarity. The proposed technique uses various methods of descriptor extraction, creation of Bag of Words dictionaries and methods of storing image data in PostgreSQL database. Further, experiments with the implemented software were carried out to evaluate the search time effectivity and scaling possibilities of the design solution.

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.

Detection of Train Axles and Their Numbering According to International Union of Railways
Dvořák, Petr ; Zamba, Martin (referee) ; Strnadel, Josef (advisor)
The diploma thesis deals with design and development of the system which detects and numbers train carriages in compliance with International Union of Railways. Firstly, methods for correct detection of passing wheel including time records are analysed. Also, the summary of detection sensors used in railway industry is referred. I analyse meaning of each digit in numbering according to the UIC. The system solution is designed and the interaction and communication with other sub-systems is discussed. I put emphasis on the kind of solution that returns as accurate record as possible under any circumstances. The system operates in real time. Further, the results of measuring program are back-tested in order to verify low-deviation of measuring system component. The following section describes program prototype, which processes the recorded data. The algorithms which I used for the detection of wheel and train carriages are described. In the following chapter I discuss the usage of an external camera detecting the numbers in accordance to the UIC. In the last chapter, I describe the test environment in which the solution has been tested, and summarize the results of tests on a real life railway.
