Attacks on active network elements
Ščepko, Richard ; Kacálek, Jan (referee) ; Polívka, Michal (advisor)
The bachelor thesis deals with the topic of the security of computer networks. The tasks of the bachelor thesis are the attacks on active network elements with the aim of the catching of data between two users. In the created structure with a stellate topology, the user stations have connect to the active element (switch). In the thesis, the individual ways of attacks and the significance of ARP proceedings to MAC addresses have describ. Several programmes have use in order to take control over the device. Due to a big amount of these active elements the source code of the programmes had to be alter. The work with the programmes ARPtool and ARPoison demanded the operational system Linux, in our case the distribution of Ubunt. The programme WinArpAttacker could be set off under the system Windows XP as well. The achieved results and the description of the practical part are discuss in detail in the summary of the thesis. The result is the catching communication with the help of the programme WireShark.

Orienteering club support system
Buk, Jindřich ; Vojíř, Stanislav (advisor) ; Sklenák, Vilém (referee)
Nowadays, an increasing number of processes and life situations is getting IT support. Often the use of the Internet aims to accelerate and simplify existing processes. In addition, there is a big area of social networking that can be complementary. This thesis deals with the possibilities of using web technologies to support the running of a club and its subsequent development. Indeed, the club has the potential to simplify and automate many processes which previously have been carried out by someone in person. It has also a potential to use social networks for its publicity and development. The aim is to first determine what areas of the clubs operations are the most appropriate to be supported by any information system. Another objective is to find out how other clubs already integrate any information systems. The final objective is to design and create a specific application. The first two objectives are addressed through a survey among the leaders of the biggest Czech clubs. Indeed in these clubs, the use of automation and simplification of existing processes could have a great potential. The proposal for a specific application is then based on the previous survey and the field experience of the author. While serving many existing processes in running the club, the proposed application adds many elements of social networking.

Case study on utilizing of heat from the nuclear power plant Dukovany in the district heating system
Kozel, David ; Drbošal, Jan (referee) ; Pospíšil, Jiří (advisor)
In this thesis, I was solved assessment of nuclear power plant Dukovany, conection to the hot water network to city Brno. For determine the size needful enforcement was necessary to establish the heat balance of needs of the city of Brno and the size of the heat supply options. After that it was possible to determine the dimensions of pipes and optimize his routes of due to the current state of land along the route of thermal power supply. Power supply parameters were chosen with regard to the possibilities of technology used for transmission of the media and the status quo for distribution of the city Brno. After pushing the power supply ahead of the city Brno into the pumping station Bosonohy, and second part of the solution was the connection to the backbone wiring SCZT heat to individual customers. The last point was elaborated design management system of heat from nuclear power plant and urban local based resources on current management of heat supply system using consumption diagrams SCZT.

Classification Mining Modules of Data Mining System on NetBeans Platform
Kuzma, Norbert ; Šuška, Boris (referee) ; Šebek, Michal (advisor)
This bachelor thesis deals with the data mining and the creation of data mining unit for data mining system, which is beeing developed at FIT. This is a client application consisting of a kernel and its graphical user interface and independent mining modules. The data mining system is implemented in Java language and its graphical user interface is built on NetBeans platform. The content of this work will be the introduction into the issue of knowledge discovery and then the presentation of neural networks, for which there will subsequently be implemented the stand-alone data mining module. Furthermore, the implementation of this modulewill be described.

Collection of laboratory works for demonstration of computer attacks
Plašil, Matouš ; Ležák, Petr (referee) ; Burda, Karel (advisor)
Diploma thesis describes published attacks on computers and computer networks. Principles of footprinting such as availability check, OS detection, port scanning were described. Next part explains attacks on confidentiality, integrity and availability. In the practical part were created four laboratory tasks and a virtual environment which allowed testing of ARP spoofing, DNS spoofing, SSL strip, Cross-site scripting, SQL injection, flooding attacks (TCP, ICMP, UDP), TCP reset and attack on operating system using backdoor with Metasploit framework. In practical part were also created video samples with attacks and documentation for teachers.

Robot vision with industrial robots Kuka
Krutílek, Jan ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
Diploma thesis deals with a robot vision and its application to the problem of manipulation of coincidentally placed objects. There is mentioned an overview of current principles of the most frequently used vision systems on the market. With regard to the required task to be solved, there are mentioned various possibilities of using basic softsensors during the recognition of different objects. The objective of this Diploma thesis is also programming and realization of a demonstration application applying knowledge of PLC programming, knowledge of expert programming KRL language (for KUKA robots), knowledge of designing scripts for smart camera in Spectation software and knowledge of network communication among all devices used in this case.

Primary School Teacher - the Relationship Between Theory and Practice in the Professional Training
Urbanová, Radka ; Štech, Stanislav (advisor) ; Smetáčková, Irena (referee)
This work deals with permanent and yet actual subject of the relationship of theory and practise in education of teachers. The main subject is connected closely to professional identity of primary school teachers, as well. First of all, the theoretical part of this work focuses on the relationship of theory and practise. It's based on works of both Czech and foreign authors, specifically German and Swiss ones. Because there are different systems of teacher-preparation in these countries, the view on theory-practise relationship is different in many points, as well. Theoretical part is divided into five chapters. First one presents primary school teacher and shows his typical features which differentiate him from teachers in another levels of education. The second chapter describes a concept of pedagogical education of teachers. The third chapter deals with how differently may concept "practise" be percieved in context of their mutual relationship. The fourth chapter describes the relationship of theory and practise in pedagogy and the last, fifth one is the most comprehensive one and is further divided into three chapters.
