Weighting System Program Support
Meisl, Milan ; Straka, Martin (referee) ; Chmelař, Petr (advisor)
Topic of the bachelor's thesis is the weighting system programme support. The main aim of the thesis is to create an application that is able to record data on weighted elements quickly and effectively. Partial aim of the thesis is to programme a communicative module of a programme for communication between the scale and the personal computer. In order to make the weighting process quick enough, it is necessary to ensure its automatic running. The application is programmed by means of modern programming technologies.

Information Retrieval
Šabatka, Pavel ; Bartík, Vladimír (referee) ; Chmelař, Petr (advisor)
The purpose of this thesis is a summary of theoretical knowledge in the field of information retrieval. This document contains mathematical models that can be used for information retrieval algorithms, including how to rank them. There are also examined the specifics of image and text data. The practical part is then an implementation of the algorithm in video shots of the TRECVid 2009 dataset based on high-level features. The uniqueness of this algorithm is to use internet search engines to obtain terms similarity. The work contains a detailed description of the implemented algorithm including the process of tuning and conclusions of its testing.

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.

Knowledge Discovery in Object Relational Databases
Chytka, Karel ; Vrážel, Dušan (referee) ; Chmelař, Petr (advisor)
The goal of this master's thesis is to acquaint with a problem of a knowledge discovery and objectrelational data classification. It summarizes problems which are connected with mining spatiotemporal data. There is described data mining kernel algorithm SVM. The second part solves classification method implementation. This method solves data mining in a Caretaker trajectory database. This thesis contains application's implementation for spatio-temporal data preprocessing, their organization in database and presentation too.

Network Attack Capture Using Honeyd Tool
Bláha, Lukáš ; Chmelař, Petr (referee) ; Drozd, Michal (advisor)
The bachelor thesis deals with Honeyd tool and its effectivity in capturing network attacks. At the beginning, there is a description of honeypots and its utilization in network security. An important part of the thesis is constituted by a practical implementation of network attacks and their analysis. The main goal is to create an extension for Honeyd tool which can emulate file sharing in operation systems Microsoft Windows XP, especially its free accessible part called null session. As results there are tests evaluating the level of detection of computer attacks by the created tool.

Evidence Database System of Health Implantable Devices
Dluhoš, Ondřej ; Chmelař, Petr (referee) ; Jaša, Petr (advisor)
This bachelor thesis creates a new database system for the company Timplant, which produces and delivers dental surgical implants and their accessories. The task of the project is to analyze the original system design and to create a new database system with use of a freeware. The database will be designed in accordance with the demands of the company and will archive all the data as required by the current government regulations.

Multiple Document Type Diff
Zemko, Michal ; Jirák, Ota (referee) ; Chmelař, Petr (advisor)
During the work on important projects, we have to backup current versions periodically. But sometimes we want to know what changes between two versions has been made. To recognize these changes, we can use the diff program that compares two text files line by line and can show differencies in various formats. A problem occurs, if we want to compare other than text files. The purpose of this bachelor thesis is to create one tool that can compare different types of files, for example images, Open Office files, DTP system LaTeX files, config files and, of course, standard text files. Each of listed types is specific and demands unique approach. This thesis deals with theoretical analysis of the problem and also with realization of the program which executes the comparision.

XML Transformation and Persistence in Relational Database
Hernych, Radim ; Rychlý, Marek (referee) ; Chmelař, Petr (advisor)
This master's thesis deals with problems of effective storage and querying of XML documents in A relational database. In the first part of this thesis XML and related technologies are described, with emphasis on languages for XML Schema definition and it's querying. Then an XML mapping method based on Hybrid method and XML Schema is described here. Hereafter the design and implementation of a native XML database front-end for object-relational database is described. Designed front-end allows storing and querying of XML documents into the underlying database. The last part contains results and evaluation of performance tests of the implemented system.

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.
