Finding the network architecture for alarm transmission system LAN-RING
Mikšíček, Pavel ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This master’s thesis deals with a complex solution for the visualization of network topology. The first part of thesis describes the operation principle of LLDP protocol, which was chosen as a tool for retrieving informations from network traffic based on the requirement of the assignment. There is a detailed description of the LLDP protocol implementation in C language to METEL s.r.o. network products. The second part deals with possibilities of graphical interface in software SIMULand intended for managing network devices. It describes tools expansion process for the visualization of the network topology. In conclusion, the results of testing final solution are introduced.

Visualization of air jet from ventilation outlet of a passenger car dashboard
Bečica, Radek ; Bělka, Miloslav (referee) ; Lízal, František (advisor)
Goal of this master´s thesis is to experimentally analyse air jet from ventilation outlet of a passenger car dashboard using smoke visualization and to describe this air jet. Air flow was set at 30 m3/h according to requirements from Škoda Auto s.r.o. from previous experiments on a similar ventilation outlet. First type of measuring rig which was developed for previous experiments was disassembled and replaced with a new modern measuring rig which is supposed to be used for next visualizations and experiments. Visualization was performed using smoke method and laser light plane. Air jet was photographed for five defined ventilation outlet adjustments and that for a jet to free space and for a jet flowing along a wall. The wall represented a front left door of a car. Results were processed by computer and presented as pictures and tables. Resulting angles were transformed to the main coordinate system of a car. Ventilation outlet functionality with respect to the air distribution in a car was evaluated afterwards.

Detection of spatial objects in a point cloud
Venený, Petr ; Machotka, Radovan (referee) ; Volařík, Tomáš (advisor)
The diploma thesis deals with processing of a point cloud that was collected via mobile mapping system. The first part sets a theoretical background, starting with mapping in general moving to mobile mapping systems and their particular parts. The practical part describes the whole process of data collecting, testing the automatic detection of spatial objects based on a point cloud and its visualisation. The results of the diploma thesis are GIS data layers and an evaluation of the process.

Attribute based authentication
Chwastková, Šárka ; Hajný, Jan (referee) ; Dzurenda, Petr (advisor)
This thesis deals with attribute based credentials. It describes attribute systems, their entities and properties generally. The work concentrates specifically on the attribute system Identity Mixer. The process of communication of the attribute system Identity Mixer is implemented in the language of JavaScript. Application is the web visualization, which describes protocols, entities and generally computes protocols of Identity Mixer with inputs of small numbers or predefined large numbers.

eGovernment: Processing of Information About Economic Subjects
Konvalinka, Petr ; Burgetová, Ivana (referee) ; Očenášek, Pavel (advisor)
This bachelor's thesis deals with eGovernment of the Czech Republic, as in terms of information technology, as well as legislative. The thesis describes selected registers of eGovernment of the Czech Republic, especially ARES information system, which is used in proposition of practical part of the thesis. The outcome of the thesis is the aplication that retriever data from multiple registers. Data are combined are visually interpreted to user. The aplication is created with assistance of QT Libraries of language C++.

User-Friendly Animated Communication with OLAP System
Kupčík, Jaroslav ; Šuška, Boris (referee) ; Hruška, Tomáš (advisor)
Complexity of multidimensional data models and its usage does not have positive influence on quality of user-friendliness of application working with them. The option of solution of negative influence of this fact on laic end-user is usage of visualisation technics for upgrade of user interface of the system. Nowadays there are powerful tools usable for impressive manipulation of originally static document on the client side. By using them, interface of the system can be enhanced with an interactive help. Usability of this modul has to satisfy maximal portability requirements. Important aspect is also range and methods of configurability of result of practical part of thesis.

Application for Data Presentation and Modification in Mobile Devices
Kučera, Pavel ; Ryšavý, Ondřej (referee) ; Trchalík, Roman (advisor)
This thesis is aimed to study the possibility of usage of mobile devices in the sphere of automation. One automation company needed to have in hand some PDA-based tool for a remote control of the technological process. There is analysis of ability of contemporary portable devices to run a application software. According to the specified requirements there is designed and implemented the client-server system based on the VNC technology. The server is a Linux-based PC server implemented using Xinetd daemon and the Xvnc. The two standard VNC clients were made. A free software available under the GPL license was modified to implement them. One runs on Windows Mobile operating system and the other one is a Java MIDlet.

Controling the dust exhaust of smeltery for recyclation of aluminum waste
Jakubský, Ondřej ; Nadrchal, Zdeněk (referee) ; Trnka, Vladislav (advisor)
The work deals with controlling and visualizing technology of dust exhaust of smeltery for recyclation of aluminum waste. In the first part of the work are analyzed the different ways of automatic control. Based on the analysis is proposed control system configuration, algorithm of control, communication interfaces and sensors of alarm, measurement and regulation. The second part deals with visualization and remote administration of control system. On the basis of selection for the visualization software is designed and implemented a system that provides visualization of technology, the archiving of measured operating values, events and errors.
