Simulation of a Golf Ball Trajectory from Video
Hlobil, Marek ; Ševcovic, Jiří (referee) ; Chmelař, Petr (advisor)
This work deals with the golf ball flight simulation based on video recordings. The way how to determine the trajectory of a golf ball using several initial points is described here. For the ball recognition there are used computer vision techniques, particulary pattern recognition. The work covers physics of the golf ball, it deals with physical influences that occurs during the ball flight and it tries to describe the trajectory approximation.

Information System for the Support of the Trainig Activities
Smékalová, Pavlína ; Chmelař, Petr (referee) ; Očenášek, Pavel (advisor)
This Diploma thesis describes the process of analysis and design of an information system supporting training activities. The system is based on the web pages. It is creating an information system, that would allow monitoring the nutritional plan, strength training and sports activities of an athlete. The system allows each athlete to be assigned a dietitian and a coach, who take care of his/her nutritional plan and training. The athlete has immediate feedback atd of his success and has better conditions to meet his ambitions.

Software Support for PLC Automation Systems
Kříž, Karel ; Ševcovic, Jiří (referee) ; Chmelař, Petr (advisor)
This thesis mainly deals with the study of communication protocols between process control systems of company Siemens and their superstructural systems (SCADA/HMI) the Ethernet interface. This is a management systems, which are mainly used by Aucon s.r.o. in practice. It also deals with OPC servers, and their use with client applications. Emphasis is placed on the theoretical analysis of certain types of inter-processcommunication in Windows. From the simple one to the model COM, which is the basis of the OPC technology. Practical part realize implementation of a simple programming interface, providing communications with equipment Siemens Simatic S7. This is realized by C++ with using WinSock2 a IPHlpApi libraries. This interface can be used at programming client application.

Semantic Web - Tutorial and Examples
Hanyáš, Petr ; Chmelař, Petr (referee) ; Očenášek, Pavel (advisor)
This thesis deals with design and realization of interactive presentation consists of tutorial which topic is "Semantic Web" and related demonstration examples with comments. Thesis is also consists of users' and commentaries' administration, testing system with random generation of questions, fulltext search engine and description of ontology editors. The aim of whole thesis is to create educational materials with a possibility of checking reached level of knowledge. Motivation for making this thesis was lack of complete materials in Czech language dealing with this problem. My aim was to create these kinds of materials so it can be intelligible to wide range of readers.

Program Suport for Fair Trade
Krivosudský, Juraj ; Stryka, Lukáš (referee) ; Chmelař, Petr (advisor)
This work has been created as a support for non-profit NGO Society for Fair Trade and Development Education. It's aimed to build a base of an information system, that will be able to integrate and simplify the organisation's running. In the actual version it's foremost about stock control system unifying the management of commodities on several affiliates and synchronization of book entries for accounting purposal. To make the further development easier, several modular components are introduced. The system is based on technologies of PHP and MySQL with additional functionality of JavaScript which is, for the sake of widest compatibility possible, minimalised and substituted with alternative solutions if possible.

Interactive Visualization of XML
Kubíček, Daniel ; Stryka, Lukáš (referee) ; Chmelař, Petr (advisor)
This bachelor's thesis is engaged in problem of visualization XML. In the first part, there is described XML language in brief and his basic characterization. There is resumed the possibility of XML usage, his advantage, XML syntax and logical structure. Bachelor's thesis also describes the problematic of reading XML in Java. The thesis is engaged in problems of XML visualization. There are summarized XML properties, advantages and disadvantages of available visualization tools in short. The Implementation chapter describes choosing of suitable programming language and development system. It briefly defines available modeling tools with individual reasons why they couldn't be used. The developed application contains two types of displaying XML elements, the basic type and the aggregation type. The program output is supposed to be practical and usable visualization tool, although many extensions can be made.

Radiography image preprocessing tools
Chmelař, Petr ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
This thesis deals with design and realization of methods of preprocessing of X-ray images and its storage. In the first part of this thesis, there were designed and implemented methods for preprocessing of series of X-ray images such as averaging after image registration or merging of images to a HDR image using Debevec method. In the following part of the thesis, there was done a literary research of data formats based on which was implemented a library for x-ray images storage. Both implemented methods allow to reduce a random noise by merging a series of images. Application of the Debevec method also allow to increase a dynamic range of image.
